• expectations regarding the Streams of Metalla;
• royalty payments to be paid to Metalla by property owners or operators of mining projects pursuant to each Royalty;

Estimates of mineral resources and mineral reserves are also forward-looking statements because they involve estimates of mineralization that will be encountered in the future, and projections regarding other matters that are uncertain, such as future costs and commodity prices.

Forward-looking statements are based on a number of material assumptions, which management of Metalla believe to be reasonable, including, but not limited to, the continuation of mining operations from which Metalla will purchase precious or other metals or in respect of which Metalla will receive Royalty payments, that commodity prices will not experience a material decline, mining operations that underlie Streams or Royalties will operate in accordance with disclosed parameters and achieve their stated production outcomes and such other assumptions as may be set out herein.

Although Metalla has attempted to identify important factors that could cause actual actions, events or results to differ materially from those contained in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that such information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such forward-looking statements. Accordingly, readers should not place undue reliance on forward-looking statements. Investors and readers of this AIF should also carefully review the risk factors set out in this AIF under the heading "Risk Factors".

Technical and Third-Party Information and Cautionary Note for United States Readers

Except where otherwise stated, the disclosure in this AIF relating to properties and operations in which Metalla holds Royalty, Stream or other interests, including the disclosure in this AIF under the heading "Material Assets" is based on information publicly disclosed by the owners or operators of these properties and information/data available in the public domain as at the date hereof, and none of this information has been independently verified by Metalla. Specifically, as a Royalty or Stream holder, Metalla has limited, if any, access to properties on which it holds Royalties, Streams, or other interests in its asset portfolio. The Company may from time to time receive operating information from the owners and operators of the mining properties, which it is not permitted to disclose to the public. Metalla is dependent on, (i) the operators of the mining properties and their qualified persons to provide information to Metalla, or (ii) on publicly available information to prepare disclosure pertaining to properties and operations on the properties on which the Company holds Royalty, Stream or other interests, and may have limited or no ability to independently verify such information. Although the Company does not have any knowledge that such information may not be accurate, there can be no assurance that such third-party information is complete or accurate. Some reported public information in respect of a mining property may relate to a larger property area than the area covered by Metalla's Royalty, Stream or other interest. Metalla's Royalty, Stream or other interests may cover less than 100% of a specific mining property and may only apply to a portion of the publicly reported mineral reserves, mineral resources and or production from a mining property.

- 4 -

As at the date of this AIF the Company considers its Royalty and Stream interests in a portion of the Côté deposit and all of the Gosselin deposit which form the Côté gold project (collectively, the "Côté Property") and in the Taca Taca copper-gold-molybdenum ‎project in Salta Province, Argentina ("Taca Taca Property" or "Taca Taca Project") to be its only material mineral properties for the purposes of National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"). Information included in this AIF with respect to the Côté Property and with respect to the Taca Taca Property has been prepared in accordance with the exemption set forth in section 9.2 of NI 43-101.

Unless otherwise noted, the disclosure contained in this AIF of a scientific or technical nature for the Côté Property is based on the technical report entitled "Technical Report on the Côté Gold Project, Ontario, Canada - Report for NI 43-101" having an effective date of June 30, 2022 which technical report was prepared for IAMGOLD Corporation ("IAMGOLD"), and filed under IAMGOLD's SEDAR+ profile on www.sedarplus.ca, and information that has been provided by IAMGOLD and/or has been sourced from their news releases with respect to the Côté Property.

Unless otherwise noted, the disclosure contained in this AIF of a scientific or technical nature for the Taca Taca Property is based on the amended and restated ‎technical report entitled "Taca Taca Project - Salta ‎Province, Argentina - Amended and Restated NI 43-101 Technical ‎Report" having an effective date of October 30, 2020, which technical ‎report was prepared for First Quantum Minerals Ltd. ("First Quantum") and filed under ‎First Quantum's SEDAR+ profile on www.sedarplus.ca, and information that has been provided by First Quantum and/or has been sourced from their news releases with respect to the Taca Taca Property.

Unless otherwise indicated, all of the mineral reserves and mineral resources disclosed in this AIF have been prepared in accordance with NI 43-101. Canadian standards for public disclosure of scientific and technical information concerning mineral projects differ significantly from the requirements adopted by the United States Securities and Exchange Commission (the "SEC").

Accordingly, the scientific and technical information contained in this AIF, including estimates of mineral reserves and mineral resources, may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.

Charles Beaudry, M.Sc., P.Geo. and géo. for Metalla and a "Qualified Person" under NI 43-101 has reviewed and approved the written scientific and technical disclosure contained in this AIF.

On July 29, 2020, Metalla announced that it had reached an agreement with Beedie Capital ("Beedie") to amend and restate (the "First Amended and Restated Beedie Loan") its existing convertible loan facility (the "Original Beedie Loan", collectively with the First Amended and Restated Beedie Loan, and as further amended from time to time, the "Beedie Loan Facility") pursuant to which (i) Beedie converted C$6.0 million of the outstanding C$7.0 million principal amount drawn under the Original Beedie Loan (the "Initial Advance") at a conversion price of C$5.56 per Common Share for a total of 1,079,136 Common Shares; (ii) the conversion price of the previously undrawn C$5.0 million tranche of the Original Beedie Loan was increased from C$5.56 to C$9.90 per Common Share; and (iii) the aggregate amount available under the Beedie Loan Facility was increased by an additional C$20 million. The second drawdown of C$5.0 million (the "Second Advance") pursuant to the Amended and Restated Beedie Loan occurred on August 6, 2020 at a conversion price of C$9.90 per Common Share.

The remaining C$1.0 million outstanding under the Initial Advance was converted by Beedie on October 30, 2020 at a conversion price of C$5.56 per Common Share, representing a 25% premium to the 30-day volume-weighted-average price ("VWAP") per Common Share as of March 15, 2019, for a total of 179,856 Common Shares.

On March 17, 2021, Metalla completed a drawdown of C$5.0 million the Beedie Loan Facility (the "Third Advance") and the Second Advance was converted by Beedie at a conversion price of C$9.90, representing a 27% premium to the 30-day VWAP per Common Share as of July 28, 2020, for a total of 505,050 Common Shares. The Third Advance may be converted by Beedie at a price of C$14.30 per Common Share, representing a 20% premium to the 30-day VWAP of the Common Shares on the TSXV calculated as of March 16, 2021, in accordance with the terms of the Beedie Loan Facility.

- 11 -

On October 1, 2021, Metalla completed a fourth drawdown of an additional C$3.0 million (the "Fourth Advance") under the Beedie Loan Facility. The Fourth Advance may be converted by Beedie at a price of C$11.16 per Common Share, representing a 20% premium to the 30-day VWAP of the Common Shares on the TSXV calculated as of September 30, 2021, in accordance with the terms of the Beedie Loan Facility.

On August 9, 2022, the Company and Beedie entered into an agreement (the "First Supplemental Loan Agreement") to extend the maturity date of the Beedie Loan Facility from April 21, 2023, to January 22, 2024 (the "Loan Extension"). In consideration for the Loan Extension the Company incurred a fee of 2.0% of the drawn amount at that time, which was C$8.0 million. The C$160,000 fee will be convertible into Common Shares at a conversion price of C$7.34 per Common Share, calculated based on a 20% premium to the 30-day VWAP of the Common Shares on the trading day immediately prior to the effective date of the Loan Extension.

Effective March 31, 2023, the Company and Beedie entered into a supplemental agreement (the "Second Supplemental Loan Agreement") to amend the Beedie Loan Facility by:

• extending the maturity ‎date to May 10, 2027;
• increasing the Beedie Loan Facility by ‎C$5.0 million from C$20.0 million to C$25.0 million;
• increasing the interest rate from ‎‎8.0% to 10.0% per annum;
• amending the conversion price of the Fourth Advance from C$11.16 to C$8.67 per Common Share, representing a 30% premium to the 30-day VWAP of the Common Shares on the TSXV calculated on the day prior to the announcement of the Second Supplemental Loan Agreement; ‎
• amending the conversion price of C$4.0 million of the Third Advance from C$14.30 to C$7.33 per Common Share, representing the 5-day VWAP of the Common Shares on the TSXV calculated on the day prior to the announcement of the Second Supplemental Loan Agreement, and converting the C$4.0 million into ‎545,702 Common Shares at the new conversion price; and
• amending the conversion price of the ‎remaining C$1.0 million of the Third Advance from C$14.30 to C$8.67 per Common Share, representing a 30% premium to the 30-day VWAP of the Common Shares on the TSXV calculated on the day prior to the announcement of the Second Supplemental Loan Agreement.

The Beedie Loan Facility is secured by certain assets of Metalla and can be repaid with no penalty at any time after the 12-month anniversary of each advance.

On October 19, 2023, Metalla and Beedie entered into an amended and restated convertible loan facility agreement (the "Second Amended and Restated Convertible Loan Agreement"), which became effective as at the closing of the Arrangement. Pursuant to the Second Amended and Restated Convertible Loan Agreement, the parties agreed:

• to increase the Beedie Loan Facility from C$25.0 million to C$50.0 million;

• to drawdown C$16.4 million (convertible at a conversion price of C$6.00 per Common Share), to refinance the C$4.2 million principal outstanding under the Beedie Loan Facility as at the time of the closing of the Arrangement, and the C$12.2 million principal outstanding under Nova's convertible loan facility with Beedie Capital (the "Nova Convertible Loan"), plus C$2.7 million, being the aggregate accrued and unpaid interest and fees outstanding under the Nova Convertible Loan and the Beedie Loan Facility as at the time of the closing of the Arrangement, with the interest convertible at a conversion price as of the date of conversion and unpaid fees shall not be convertible, plus an amendment fee of approximately C$0.1 million payable to Beedie, plus certain expenses of Beedie (collectively, the "Initial Drawdown");

• that the interest on the principal will accrue at a rate of 10.0% per annum;

- 12 -

• for an eighteen-month period from the close of the Arrangement, accrued interest will be capitalized and added to the principal amount, and thereafter, at Metalla's election, 2.0% per annum of the interest accruing on the principal will be capitalized and added to the principal amount;

• that the standby fee (1.5% per annum), the commitment fee (1.0% on any subsequent advance (not payable on the Initial Drawdown)), the make whole fee (entitling Beedie to earn a minimum of 12 months of interest on each advance made) and the default interest rate (14.0% per annum) remain the same; and

• to update existing security arrangements to reflect security provided by Nova and its subsidiary for the Beedie Loan Facility, along with updated security arrangements at Metalla to reflect developments in our business.

Concurrent with closing of the Arrangement, Metalla drew down on the Beedie Loan Facility and paid out and discharged all obligations under the Nova Convertible Loan, and the Nova Convertible Loan has been terminated.

Any future advances from the remaining C$30.9 million made available by Beedie under the Beedie Loan Facility will require a minimum drawdown of C$2.5 million by Metalla with a conversion price based on a 20% premium to the 30-day VWAP of the Common Shares on the date of such advance.

DESCRIPTION OF THE BUSINESS

Metalla is a publicly traded precious metals royalty and streaming company listed on the TSXV, NYSE and Frankfurt Exchange. Metalla's business model is focused on managing and growing its portfolio of Royalties and Streams. Metalla's long-‎term goal is to provide its shareholders with a model which provides:‎

• exposure to gold, silver, and copper price optionality;‎

• a perpetual discovery option over large areas of geologically prospective lands which it acquires at no additional ‎cost other than the initial investment;‎

• limited exposure to many of the risks associated with operating companies;‎

• free cash-flow and limited cash calls;‎

• high margins that can generate cash through the entire commodity cycle;‎

- 15 -

• diversity that is scalable, in which a large number of assets can be managed with a small stable overhead; and

• management focus on forward-looking growth opportunities rather than operational or development issues.‎

A Royalty is a non-dilutive asset level perpetual interest in an underlying mineral project that, when in production, provides topline cash relative to the percentage of the royalty. Depending on the nature of a royalty interest, the laws applicable to it and the specific project, the royalty holder is generally not responsible for, and has no obligation to contribute to operating or capital costs or environmental liabilities. An NSR Royalty is generally based on the value of production or net proceeds received by an operator from a smelter or refinery for the minerals sold. These proceeds are usually subject to deductions or charges for transportation, insurance, smelting and refining costs as set out in the agreement governing the terms of the royalty.

A Stream provides the purchaser the right to acquire all or a portion of the future metal production from a mining project at the lesser of a defined price and the market price.

Principal Product

Since inception, Metalla has deployed over $300 million, comprised of cash consideration, Common Shares and other equity related structures, issued to sellers, across 33 transactions amassing a portfolio of over 102 Royalties and Streams. Metalla's portfolio provides exposure to established counterparties, including Agnico Eagle, Pan American, Polymetals Resources Ltd. ("Polymetals"), SSR Mining Inc. ("SSR Mining"), St. Barbara Limited, Newmont, Teck, Barrick Gold, BHP, Eldorado Gold, IAMGOLD, First Majestic, First Quantum, Aura Minerals, Los Andes Copper, Anglo American, Hudbay, Transition Metals, Pacific Empire, Lundin Mining, and many more.

The principal products of Metalla are: (i) precious metals that it has agreed to purchase pursuant to Stream agreements that it has entered into with mining companies; and (ii) Royalty payments pursuant to Royalty agreements acquired by Metalla or entered into with mining companies. Metalla is focused on precious metal streams and royalties for gold, silver and copper.

The Company's sole material assets are its Royalty interests in the Côté Property and in the Taca Taca Property. See "Material Assets" below.

Project Statuses

For this AIF, Metalla introduced a new classification scheme for each royalty asset. The four stages are ‎described ‎below. Readers should note that this classification scheme is used by Metalla for purposes of ‎categorizing its ‎own portfolio of assets; however, such classification scheme and categorization may not ‎necessarily be the ‎same as, or consistent with, the classification scheme used in our financial statements ‎and management’s discussion & analysis, which is governed by the applicable financial reporting ‎standards, or any particular owner’s classification of its property:

Production: A project is considered to be in "Production" when the underlying property, or part of it, is subject to active mining to produce a payable product and the Company's Royalty is cash flowing based on this production. "Production" includes properties that are in the later stages of their lives, such as residual leaching and stockpile processing.

Development: A project is considered to be in "Development" when the project has sufficiently initiated or completed economic studies (e.g., Preliminary Economic Assessment, Pre-Feasibility Study or Feasibility Study) or where the operator has otherwise disclosed an active plan or decision to construct mine workings including a reasonable estimate with projected costs and timeline to commence development which will lead to eventual production. In most cases, the project will have a Mineral Resource estimate and in some cases, there may also be a Mineral Reserve estimate. Generally, projects in the "Development" status will be in active construction or development towards production, while others are sufficiently advanced and will be based upon sufficient confidence of the operator that construction and development towards production will occur. Developing projects also include assets which previously had cash-flow and have been placed on Care and Maintenance or assets that are currently producing but the Company's royalty does not cover the producing part of the mine.

- 16 -

Advanced Exploration: A project is considered to be in "Advanced Exploration" when exploration work has advanced sufficiently to prepare a Mineral Resource estimate or material exploration activities are occurring or are planned to occur that are designed to support a Mineral Resource estimate on the property. Projects with historical non-compliant technical studies may be included in this category. Exploration work may include enhancing geological studies, drilling programs, technical studies, and any other work including permitting activities that would de-risk the project. Advanced Exploration projects may have had study work initiated or completed to better understand economic potential on the property, but which has generally not resulted in work being approved, initiated or advanced that would substantially progress the project towards development and eventual production.

Exploration: A project is considered to be "Exploration" when there has been primarily early-stage exploration activities (such as exploration drilling, geophysics, geochemical sampling, lithological / structural mapping, etc.) or insufficient exploration work to prepare a Mineral Resource estimate. In some cases, the project may have a historical Mineral Resource estimate or an Inferred Mineral Resource estimate, but without current material exploration work being performed or proposed to further advance the project.

(12) On August 14, 2023, Silver Storm (formerly known as Golden Tag Resources Ltd.) announced that it has acquired a 100% interest in the La Parrilla property from First Majestic.

(13) The mine was previously classified as production; however, it was placed on care and maintenance. As such, ‎the Company has reclassified it as a development stage property.‎

(14) Metalla converted its 100% silver stream in the Endeavor mine into a 4.0% NSR royalty on all lead, zinc and silver ‎produced from those mining tenements.

‎(15)‎Formerly Platinex Inc. prior to a name change announced on February 26, 2024.

(16)Metalla currently expects to acquire, through Nova, approximately 16.7% of an existing 0.5% net profit interest ("NPI") Royalty on the Josemaria copper-gold-silver project in San Juan, Argentina, owned by Lundin Mining Corporation (approximately 0.08325% NPI) for ‎total aggregate consideration of $2.4 million, with a right of first refusal over an additional 16.7% of the royalty ‎‎(approximately 0.08325% NPI).‎

‎(17)‎The total royalty payable is ½ of the U.S. Government royalty, which was most recently quoted at 4.8%. The U.S. ‎government royalty is subject to change, which would change the royalty payable to Metalla. The royalty currently ‎payable to Nova is calculated in the following formula: 4.8% * ½ * 1/3 * ore mined * grade mined * applicable prices ‎of copper and nickel. The royalty is calculated on the basis of contained metal in ore by multiplying ore mined by ‎the grade of the material - and does not subtract the usual deductions due to recoveries, payabilities, TC/RCs, and ‎other applicable operating costs. The 1/3 multiplier in the royalty calculation formula is the mechanism by which ‎those usual costs are captured. In the technical report, copper reserves are calculated using recoveries of 94.0% ‎and payabilities of 76.4% and nickel reserves are calculated using recoveries of 60.8% and payabilities of 70.8%.‎

(18)The Higginsville participation royalty was for delivery of a total of 34,000 gold ounce; that threshold was reached in the fourth quarter of 2023 and as such the royalty is no longer payable to Metalla.

Further details regarding the purchase agreements entered into by Metalla in respect of certain Stream and Royalty acquisition agreements with respect to development or production properties can be found under the heading General Development of the Business‎ above.

Competitive Conditions

Metalla will compete with other companies that operate in the Stream and Royalty market segment to acquire Streams and Royalties. Metalla will also compete with companies that provide financing to mining companies. Metalla also competes with other precious metals focused companies for capital and human resources. See section "Description of the Business - Risk Factors - Competition".

Components

Metalla expects to purchase or acquire Royalties or Streams as previously described above under the heading Description of the Business.

Employees

As at the date of this AIF, but after giving effect to the departure of Drew Clark described under "General Development of the Business - Current Business of Metalla - 3 Year History", Metalla has a total of 4 full-time and 4 part-time employees. No management functions of Metalla are performed to any substantial degree by persons other than the directors and executive officers of the Company.

Foreign Operations

Metalla currently purchases or expects to purchase precious or other metals or receives or expects to receive payments under Royalties from mines or operations in Australia, Argentina, Mexico, Canada, Tanzania, Ecuador, Peru, Chile, Brazil, Venezuela and the United States. Metalla may in the future purchase precious metals or receive payments under Royalties from mines or operations in other countries. Changes in legislation, regulations or governments in such countries are beyond Metalla's control and could adversely affect the Company's business. Metalla may also be exposed to political, economic or other risks and uncertainties, including a risk of war or civil unrest. In particular, the Company's business could be materially adversely affected by the conflict in the Middle East or between Russia and Ukraine, which could in turn have potential impacts on commodity prices and negative implications on the financial markets. The effect of these factors cannot be predicted with any accuracy by Metalla or its management. See section "Description of the Business - Risk Factors - International Interests" in this AIF.

RISK FACTORS

Investing in the securities of the Company is speculative and involves a high degree of risk due to the nature of our business and the present ‎stage of its development. The following risk factors, as well as risks currently unknown to us, could materially and adversely affect ‎our future business, operations and financial condition and could cause them to differ materially from the estimates described in ‎forward-looking statements relating to the Company, or its business, property or financial results, contained herein, each of which could cause purchasers of our securities to lose part or all of their ‎investment. The risks set out below are not the only risks we face; risks and uncertainties not currently known to us or that we ‎currently deem to be immaterial may also materially and adversely affect our business, financial condition, results of operations ‎and prospects.

Investors should carefully consider all of the information disclosed in this AIF prior to investing in the securities of Metalla. In addition to the other information presented in this AIF, the following risk factors should be given special consideration when evaluating an investment in such securities. These risk factors could materially affect Metalla's future operating results and could cause actual events to differ materially from those described in forward-looking statements relating to Metalla. The risk factors described in this AIF are not the only risks that Metalla faces. Additional risks or uncertainties that Metalla does not have any knowledge of or are currently deemed as immaterial, could also materially adversely affect Metalla.

Risks Relating to Metalla

Changes in Commodity Prices that underlie Royalty, Stream or Other Interests

The price of Metalla's Common Shares may be significantly affected by declines in commodity prices. The revenue derived by ‎Metalla from its asset portfolio will be significantly affected by changes in the market price of commodities that underlie the Royalty, ‎Stream or other investments or interests of Metalla. Metalla's revenue is particularly sensitive to changes in the price of gold and ‎silver. Any future cash flow derived from silver Streams is dependent on the future price of silver. The price of gold, silver and ‎other commodities fluctuates daily and are affected by factors beyond the control of Metalla, including levels of supply and ‎demand, industrial development, inflation and interest rates, the U.S. dollar's strength and geo-political events. External economic ‎factors that affect commodity prices can be influenced by changes in international investment patterns, monetary systems and ‎political developments.‎

- 26 -

The Chinese market is a significant source of global demand for commodities. A sustained slowdown in China's growth or demand, ‎or a significant slowdown in other markets, in either case, that is not offset by reduced supply or increased demand from other regions ‎could have an adverse effect on the price and/or demand for the products in respect of which we have Streams, Royalties or other ‎interests. The COVID-19 pandemic and efforts to contain it have had a significant effect on commodity prices and demand as well ‎as broader impacts on the global economy. See also "Risk Factors - Risks Related to Mines and Mining Operations - Public Health ‎Crises, including the COVID-19 Pandemic may Significantly Impact Metalla"‎.

All commodities, by their nature, are subject to wide price fluctuations and future material price declines will result in a decrease in ‎revenue and may cause a suspension or termination of production by relevant operators, which would result in a complete cessation ‎of revenue from applicable Royalties, Streams or working interests. Even if Metalla works to ensure a diversification of commodities ‎that underlie its Royalties, Streams and other interests, the commodity market trends are cyclical in nature and a general downturn in ‎commodity prices could result in a significant decrease in overall revenue.‎

Metalla Has No Control Over Mining Operations

Metalla is not directly involved in the operation of mines. The revenue Metalla may derive from its portfolio of Royalty and Stream ‎assets and other interests is based entirely on production from third-party mine owners and operators. Metalla is party to precious metal ‎purchase agreements to purchase a certain percentage of precious metals or other metals produced by certain mines and operations ‎and Metalla expects to receive payments under Royalty agreements based on production from certain mines and operations, ‎however, Metalla will not have a direct interest in the operation or ownership of those mines and projects. The owners and operators ‎generally will have the power to determine the manner in which the properties are exploited, including decisions to expand and ‎continue or reduce, suspend or discontinue production from a property, to make decisions about the marketing of products extracted ‎from the property and to make decisions to advance exploration efforts and conduct development of non producing properties. The ‎interests of third-party owners and operators and those of Metalla in respect of a relevant project or property may not always be ‎aligned. The inability of Metalla to control the operations for the properties in which it has a Royalty, Stream or other interest may ‎result in a material adverse effect on the profitability of Metalla, the results of operations of Metalla and its financial condition. ‎Except in a limited set of circumstances as may be specified in respect of a specific Stream, Royalty or other interest, Metalla will not ‎receive compensation if a specific mine or operation fails to achieve or maintain production or if the specific mine or operation is ‎closed or discontinued. In addition, a number Mining Operations (as defined below) are currently in exploration stage and may not commence commercial production and there can be no ‎assurance that if such operations do commence production that they will achieve profitable and continued production levels. In ‎addition, the owners or operators may take action contrary to policies or objectives of Metalla; be unable or unwilling to fulfill their ‎obligations under their agreements with Metalla; have difficulty obtaining or be unable to obtain the financing necessary to move ‎projects forward; or experience financial, operational or other difficulties, including insolvency, which could limit the owner or ‎operator's ability to perform its obligations under arrangements with Metalla. Metalla is also subject to the risk that a specific mine or ‎project may be put on care and maintenance or have its operations suspended, on both a temporary or permanent basis.‎

The owners or operators of the projects or properties in which Metalla holds a Royalty, Stream or other interest may from time to ‎time announce transactions, including the sale or transfer of the projects or of the operator itself, over which Metalla has little or no ‎control. If such transactions are completed it may result in a new operator controlling the project, who may or may not operate the ‎project in a similar manner to the current operator which may positively or negatively impact Metalla. If any such transaction is ‎announced, there is no certainty that any such transaction will be completed, or completed as announced, and any consequences of ‎such non completion on Metalla may be difficult or impossible to predict.‎

- 27 -

Metalla is subject to the risk that Mining Operations may shut down on a temporary or permanent basis due to issues including but ‎not limited to economic conditions, lack of financial capital, flooding, fire, pandemics (including the COVID-19 pandemic), weather ‎related events, mechanical malfunctions, community or social related issues, social unrest, the failure to receive permits or having ‎existing permits revoked, collapse of mining infrastructure including tailings ponds, expropriation and other risks. ‎These issues are common in the mining industry and can occur ‎frequently. There is a risk that the carrying values of Metalla's assets may not be recoverable if the mining companies operating the ‎Mining Operations cannot raise additional finances to continue to develop those assets. The exact effect of these factors cannot be ‎accurately predicted, but the combination of these factors may result in the Mining Operations becoming uneconomic resulting in ‎their shutdown and closure. Metalla is not entitled to purchase gold, silver or other commodities, receive royalties or other economic ‎benefit from the Mining Operations if no gold, silver or other commodities are produced from the Mining Operations.‎

Variations in Foreign Exchange Rates

Foreign exchange rates have seen significant fluctuation in recent years. Effective September 1, 2020, Metalla's ‎presentation currency is the United States dollar. However, Metalla maintains an office and employees in ‎Canada, a material portion of its expenditures are incurred in Canadian dollars and it has outstanding ‎indebtedness denominated in Canadian dollars. In addition, certain of Metalla's Royalties require or permit ‎payment in, or are based on calculations using, currencies other than United States dollars. For example, the ‎Royalty on the Cap-Oeste Sur East ("COSE") mine provides that payment may be made in either Argentinian Pesos or United States ‎dollars at the option of the payor. As a result, Metalla is subject to foreign currency exchange risk. Metalla has not ‎hedged its exposure to currency fluctuations. A depreciation in the value of the United States dollar against ‎the ‎Canadian dollar or one or more of the currencies in which Metalla receives payments under the Royalties and ‎Streams could have a material adverse ‎effect on the profitability of Metalla, its results of operations and ‎financial condition. ‎

Delay Receiving or Failure to Receive Payments

Metalla is dependent to a large extent upon the financial viability and operational effectiveness of owners and operators of the ‎relevant mines and mineral properties underlying Metalla's Streams and Royalties. Payments from production generally flow through ‎the operator and there is a risk of delay and additional expense in receiving such revenues. Payments may be delayed by restrictions ‎imposed by lenders, delays in the sale or delivery of products, the ability or willingness of smelters and refiners to process mine ‎products, recovery by the operators of expenses incurred in the operation of the Royalty or Stream properties, the establishment by ‎the operators of reserves for such expenses or the insolvency of the operator. Metalla's rights to payment under the Royalties and ‎Streams must, in most cases, be enforced by contract without the protection of the ability to liquidate a property. This inhibits ‎Metalla's ability to collect amounts owing under its Royalties and Streams upon a default. Additionally, some agreements may ‎provide limited recourse in particular circumstances which may further inhibit Metalla's ability to recover or obtain equitable relief in ‎the event of a default under such agreements. In the event of a bankruptcy of an operator or owner, it is possible that an operator ‎may claim that Metalla should be treated as an unsecured creditor and, therefore, have a limited prospect for full recovery of revenue ‎and a possibility that a creditor or the operator may claim that the Royalty or Stream agreement should be terminated in the ‎insolvency proceeding. Failure to receive payments from the owners and operators of the relevant properties or termination of ‎Metalla's rights may result in a material and adverse effect on Metalla's profitability, results of operations and financial condition.‎

Reliance on Third-Party Reporting

Metalla relies on public disclosure and other information regarding specific mines or projects that is received from the owners or ‎operators of the mines or other independent experts, and certain of such information is included in this AIF. The information received may be susceptible to being imprecise as a result of it ‎being compiled by certain third parties. The disclosure created by Metalla may be inaccurate if the information received contains ‎inaccuracies or omissions, which could create a material adverse effect on Metalla. Further, Metalla must rely on the accuracy and ‎timeliness of the public disclosure and other information it receives from the owners and operators of the Mining Operations, and uses ‎such information in its analyses, forecasts and assessments relating to its own business and to prepare its disclosure with respect to the ‎Streams and Royalties. If the information provided by such third parties to Metalla contains material inaccuracies or omissions, the ‎Company's disclosure may be inaccurate and its ability to accurately forecast or achieve its stated objectives may be materially ‎impaired, which may have a material adverse effect on Metalla.‎

- 28 -

In addition, a Royalty or Stream agreement may require an owner or operator to provide Metalla with production and operating ‎information that may, depending on the completeness and accuracy of such information, enable Metalla to detect errors in the ‎calculation of Royalty or Stream payments that it receives. As a result, the ability of Metalla to detect payment errors through its ‎associated internal controls and procedures is limited, and the possibility exists that Metalla will need to make retroactive revenue ‎adjustments. Of the Royalty or Stream agreements that Metalla enters into, some may provide Metalla the right to audit the ‎operational calculations and production data for associated payments; however, such audits may occur many months following the ‎recognition by Metalla of the applicable revenue and may require Metalla to adjust its revenue in later periods.‎

As a holder of an interest in a Royalty or Stream, Metalla will have limited access to data on the operations or to the actual properties ‎underlying the Royalty or Stream. This limited access to data or disclosure regarding operations could affect the ability of Metalla to ‎assess the performance of the Royalty or Stream. This could result in delays in cash flow from that which is anticipated by Metalla ‎based on the stage of development of the properties covered by the assets within the portfolio of Metalla.‎

If ESG information provided to the Company by third parties (before and/or after entering into a transaction to ‎acquire a Mining Operation) contained or contains material inaccuracies or omissions, the Company's ‎conclusions in this regard may be inaccurate.‎

Disclosure Regarding Operations

Some Royalties or Streams may be subject to confidentiality arrangements which govern the disclosure of information regarding ‎the Royalty or Stream and, as such, Metalla may not be in a position to publicly disclose non-public information with respect to ‎certain Royalties or Streams. The limited access to data and disclosure regarding the operations of the properties in which Metalla has ‎an interest, may restrict the ability of Metalla to enhance its performance which may result in a material and adverse effect on the ‎profitability of Metalla, results of operations for Metalla and financial condition. There can be no assurance that Metalla will be ‎successful in obtaining these rights when negotiating the acquisition of Royalties or Streams.‎

Strategy for Acquisitions

As Metalla executes on its business plan, it intends to seek to purchase additional Royalties and Streams from third parties. Metalla ‎cannot offer any assurance that it can complete any other acquisition or proposed business transactions on ‎favourable terms or at all, or that any completed acquisitions or proposed transactions will benefit Metalla.

At any given time Metalla ‎may have various types of transactions and acquisition opportunities in various stages of review, including submission of indications ‎of interest and participation in discussions or negotiations in respect of such transactions. This process also involves the engagement ‎of consultants and advisors to assist in analyzing particular opportunities. Any such acquisition or transaction could be material to ‎Metalla and may involve the issuance of securities by Metalla to fund any such acquisition. Any such issuance of securities may ‎result in substantial dilution to existing shareholders and may result in the creation of new control positions. In addition, any such ‎acquisition or other Royalty or Stream transaction may have other transaction specific risks associated with it, including risks related ‎to the completion of the transaction, the project operators or the jurisdictions in which assets may be acquired.‎

- 29 -

Additionally, Metalla may consider opportunities to restructure its Royalties or Streams where it believes such a restructuring may ‎provide a long-term benefit to Metalla, even if such restructuring may reduce near term revenues or result in Metalla incurring ‎transaction-related costs. Metalla may enter into one or more acquisitions, restructurings or other Royalty and Stream transactions ‎at any time.‎

Metalla Cash Flow Risk

Metalla is not directly involved in the ownership or operation of mines. Metalla's Royalty, Stream and other interests in properties or ‎projects are subject to most of the significant risks of the operating mining company. Metalla's cash flow is dependent on the ‎activities of third parties which could create risk that those third parties may have targets inconsistent to Metalla's targets, take action ‎contrary to Metalla's goals, policies or objectives, be unwilling or unable to fulfill their contractual obligations owed to Metalla, or ‎experience financial, operational or other difficulties or setbacks, including bankruptcy or insolvency proceedings, which could limit a ‎third-party's ability to perform under a specific third-party arrangement. Specifically, Metalla could be negatively impacted by an ‎operator's ability to continue its mining operations as a going concern and have access to capital. A lack of access to capital could ‎result in a third-party entering a bankruptcy proceeding, which would result in Metalla being unable to realize any value for its ‎Stream, Royalty or other interest.‎

Negative Cash Flow from Operations

During the fiscal year ended December 31, 2023, the Company had negative cash flow from operating activities. To the extent that the Company has negative cash flow in any future period, unallocated funds may be used to fund such negative cash flow from operating activities, if any.

Rights of other Interest-Holders

Some Royalty and Stream interests are subject to: (i) buy-down right provisions pursuant to which an operator may buy back all or a ‎portion of the Royalty or Stream, (ii) pre-emptive rights pursuant to which certain parties have the right of first refusal or first offer ‎with respect to a proposed sale or assignment of a Royalty or Stream to Metalla, or (iii) claw back rights pursuant to which the seller ‎of a Royalty or Stream to Metalla has the right to re acquire the Royalty or Stream. Holders may exercise these rights such that ‎certain Royalty and Stream interests would no longer be held by Metalla or would become difficult for Metalla to acquire. Any ‎compensation received as a result may be significantly less than Metalla had budgeted receiving for the applicable Royalty or Stream ‎and may have a material adverse effect on Metalla's income and business.‎

Defects in Royalties and Streams

A defect in the Royalties and Streams and/or the underlying contract may arise to defeat or impair the claim of Metalla to such Royalty or Stream.

Such defects in a Royalty or Stream may result in a material and adverse effect on Metalla's profitability, ‎results ‎of operations, financial condition and the trading price of Metalla securities.‎

Change in Material Assets

Metalla holds a 1.35% net smelter return Royalty on the Côté Property (the "Côté Property Royalty") ‎and a 0.42% net smelter return Royalty (the "Taca Taca Royalty") on the Taca Taca Property. The Company holds the Taca Taca Royalty through its wholly-owned subsidiary, Nova.

- 30 -

As at the date of this AIF, the Côté Property Royalty and the Taca Taca Royalty are the only material assets ‎of Metalla, although as new assets are acquired or existing assets move into production, the materiality of each of the assets of Metalla will be ‎reconsidered. Any adverse development affecting the operation of, production from or recoverability of mineral reserves from the Côté Property Royalty and the Taca Taca Royalty or any other significant property in the asset portfolio from time to time, ‎such as, but not limited to, unusual and unexpected geologic formations, seismic activity, rock bursts, cave ins, flooding and other ‎conditions involved in the drilling and removal of material, any of which could result in damage to, or destruction of, mines and other ‎producing facilities, damage to life or property, environmental damage, or the inability to hire suitable personnel and engineering ‎contractors or secure supply agreements on commercially suitable terms, may have a material adverse effect on the profitability of ‎Metalla, the financial condition of Metalla and results of its operations.‎

Global Financial Conditions

Global financial conditions have been characterized by ongoing volatility. Global financial conditions could suddenly and rapidly destabilize in response to future events, as government authorities may have limited resources to respond to future crises. Global capital markets have continued to display increased volatility in response to global events. In particular, the conflicts in the Middle East and between Russia and Ukraine and any restrictive actions that are or may be taken by Canada, the U.S., and other countries in response thereto, such as sanctions or export controls, could have potential negative implications to the global capital markets. Future crises may be precipitated by any number of causes, including natural disasters, pandemics (including the COVID-19 pandemic), geopolitical instability, changes to energy prices or sovereign defaults.

Market events and conditions, including the COVID-19 pandemic, significant fluctuations in fuel and energy costs and prices, inflation and rising interest rates, political instability in the Middle East and Russia and international trade tension have resulted in commodity prices remaining volatile. These conditions have also caused a loss of confidence in global financial markets, causing consumer spending to decrease, employment rates to reach historic lows and consumer debt levels to increase. Notwithstanding various actions by governments, concerns about the general condition of the capital markets have caused these markets to be volatile. These events are illustrative of the effect that events beyond the Company's control may have on commodity prices, demand for metals, including gold, silver, copper, lead and zinc, availability of credit, investor confidence, and general financial market liquidity, all of which may adversely affect the Company's business. Global financial conditions have always been subject to volatility. Access to public financing has been negatively impacted by the COVID-19 pandemic, the effects of high interest rates and instability in the banking sector and the associated decreases in consumer spending and employment levels, as well as concerns over global growth rates and conditions.

Any sudden or rapid destabilization of global economic conditions or crisis in the credit market could negatively impact Metalla's ability, or the ability of the operators of the properties in which Metalla holds Royalties, Streams or other interests, to obtain equity or debt financing or make other suitable arrangements to finance their projects. Additionally, increased levels of volatility and market turmoil can adversely impact the operations of Metalla and the value and the price of the Common Shares of the Company could be adversely affected.

The Impact of Pandemics and Public Health Emergencies in the Future May Significantly Impact Metalla

The COVID-19 global health pandemic had a significant impact on the global economy and commodity and financial markets. Many of these impacts are still being experienced in various ways around the world. The impact of the pandemic included extreme volatility in financial markets, elevated inflation, extreme volatility in commodity prices (including gold, silver, lead, zinc, copper, molybdenum, nickel, and platinum), raised the prospect of an extended global recession and the temporary suspension of many mining operations. If the operation or development of one or more of the properties in which Metalla holds a Royalty, Stream or other interest and from which it receives or expects to receive significant revenue is suspended as a result of future pandemics or other public health emergencies, it may have a material adverse impact on the Company's profitability, results of operations, financial condition and the trading price of the Company's securities. The broader impact of future pandemics or similar public health emergencies on investors, businesses, the global economy or financial and commodity markets may also have a material adverse impact on the Company's profitability, results of operations, financial condition and the trading price of the Company's securities.

- 31 -

Dependence on Key Personnel

Metalla is dependent on the services of a small number of key management personnel. The ability of Metalla to manage its activities ‎and its business will depend in large part on the efforts of these individuals. There can be no assurance that Metalla will be successful ‎in engaging or retaining key personnel. The loss of the services of a member of the management of Metalla could have a material ‎adverse effect on the Company. From time to time, Metalla may also need to identify and retain additional skilled management and ‎specialized technical personnel to efficiently operate its business. The number of persons skilled in the acquisition of Royalties and or ‎Streams is limited and competition for such persons is intense. Recruiting and retaining qualified personnel is critical to the success of ‎Metalla and there can be no assurance that Metalla will be successful in recruiting and retaining the personnel it needs to successfully ‎operate its business. If Metalla is not successful in attracting and retaining qualified personnel, the ability of Metalla to execute on its ‎business model and strategy could be affected, which could have a material and adverse impact on its profitability, results of ‎operations and financial condition.‎

Limitations of Controls and Procedures‎

No assurances can be made that Metalla's internal controls will be effective or that Metalla will be able to maintain effective controls in the future. In addition, the Company's internal control over financial ‎reporting may not prevent or detect misstatements because of the inherent limitations of internal controls, including ‎the possibility of human error, the circumvention or overriding of controls, poorly designed or ineffective controls, or ‎fraud. As an "emerging growth company", Metalla is not currently required to obtain an auditor attestation of its ‎internal control over financial reporting. Failure to maintain effective controls, or a failure of the Company's ‎internal controls, could cause the Company to be required to amend its financial statements, subject the Company ‎to additional costs, adversely affect the Company's stock price if shareholders or other third parties have less ‎confidence in the Company, or subject the Company to potential regulatory actions. In addition, any failure to ‎implement required new or improved controls, or difficulties encountered in their implementation, could harm the ‎Company's operating results or cause it to fail to meet its reporting obligations.‎

Dividends

Payment of dividends on Metalla's securities is within the discretion of Metalla's board of directors and will depend upon Metalla's ‎future earnings, cash flows, acquisition capital requirements and financial condition, and other relevant factors. Metalla's long-term dividend policy is to pay out a target rate of 50% of the annualized operating cash flow of the Company. The board of ‎directors of the Company will continue to assess the ‎Company's ability to pay dividends in respect of a particular quarter during the 2024 financial year, but there can be no assurance that it will be in ‎a position to declare dividends in the future due to the occurrence of one or more of the risks described herein. See "Dividends" section below for additional information.‎

Competition

Metalla will compete with other companies for Streams and Royalties. Other companies may have greater resources than Metalla. ‎Any such competition may prevent Metalla from being able to secure new Streams or acquire new Royalties. Future competition in ‎the royalty and streaming sector could materially adversely affect Metalla's ability to conduct its business. There can be no ‎assurance that Metalla will be able to compete successfully against other companies in acquiring new Royalty and/or Stream ‎interests. In addition, Metalla may be unable to acquire Royalties or Streams at acceptable valuations which may result in a material ‎and adverse effect on Metalla's profitability, results of operations and financial condition.‎

- 32 -

Project Operators may not Respect Contractual Obligations

Royalty, Stream and other interests in properties or projects are contractual in nature. Parties to contracts do not always honour contractual terms and contracts themselves may be subject to interpretation or technical defects. To the extent grantors of Royalties, Stream and other interests do not abide by their contractual obligations, Metalla may be forced to take legal action to enforce its contractual rights. Such litigation may be time consuming and costly and there is no guarantee of success. Further, any such litigation may also be required to be pursued in foreign jurisdictions. Any pending proceedings or actions or any decisions determined adversely to Metalla, may have a material and adverse effect on Metalla's profitability, results of operations, financial condition and the trading price of the Common Shares.

Enforceability

The status of Royalties at law can be uncertain and varies from jurisdiction to jurisdiction and in certain jurisdictions a Royalty may ‎not be a registrable interest which is an interest land. As a result, it may be difficult for Metalla to enforce its rights with respect to ‎Royalties against a third party. Such a failure may result in the loss of the Company's rights to such a Royalty in the event a third ‎party assigns title to the underlying property.‎

Conflicts of Interest

Certain directors and officers of Metalla also serve as directors, officers and/or advisors of other companies that are involved in natural ‎resource explorations, development and mining operations, including Galena Mining Limited, Azarga Metals ‎Corp., Enduro Metals Corporation, Silver Hammer Mining Corp., MTB Metals Corp., GT Resources Inc., ‎Comet Resources Limited, Tempus Resources ‎Limited, K92 Mining Inc., Nova Royalty Corp., Osisko Mining Inc., and Clover Leaf Capital Corp. and, consequently, ‎there exists the possibility for such directors and officers to be in a position where there is a conflict of interest. Any decision made by ‎any such directors and officers will be made in accordance with their duties and obligations to deal in good faith and in the best ‎interests of Metalla and its shareholders. Each director that is in a conflict of interest is required to declare such conflict and abstain ‎from voting on a matter in which that director is conflicted in accordance with applicable law.‎

Future Financing Requirements

Metalla expects that it will require additional financing in the future, to fund new acquisitions, to make required installment, milestone and contingent payments under prior acquisition agreements, for general corporate purposes and, unless indebtedness is converted to equity, for debt repayment. There can be no assurance that Metalla will be able to obtain adequate financing in the future, that it will satisfy ‎the requirements to draw additional funds under the Beedie Loan Facility, that it will raise additional capital through any financing or that the terms of any financing ‎will be favourable. Failure to obtain such additional financing or satisfy the requirement for additional draws ‎under the Beedie Loan Facility could impede the funding obligations of Metalla or result in delay or ‎postponement of further business activities which may result in a material and adverse effect on Metalla's ‎profitability, results of operations and financial condition. Metalla may require new capital to continue to grow its ‎business and there are no assurances that capital will be available when needed, if at all. It is likely that, at least ‎to some extent, such additional capital will be raised through the issuance of additional equity or convertible ‎debt, which could result in dilution to shareholders.‎

See "Risk Factors - Dilution".

Compliance with Terms and Repayment of Credit Facilities

There can be no assurance that the Beedie Loan Facility, or any other credit facilities or financing ‎agreements that Metalla may enter into, will be renewed or refinanced, ‎or if renewed or refinanced, that ‎the renewal or refinancing will occur on equally favourable terms to Metalla, that Metalla will be able to comply with the covenants and other obligations under these agreements, that the indebtedness thereunder will be converted to Common Shares by the holder thereof, or that Metalla will be able to raise sufficient capital to repay such indebtedness when required. Metalla's ability to ‎continue ‎operating may be adversely affected if Beedie does not convert the loans outstanding under the Beedie ‎Loan Facility into equity of Metalla, if Metalla is not able to renew the Beedie Loan Facility or any other ‎credit facilities or arrange refinancing, or if such ‎renewal or refinancing, as the case may be, occurs on ‎terms materially less favorable to Metalla than at present. The Beedie Loan Facility is secured by a ‎substantial portion of Metalla's assets, and imposes covenants and obligations on Metalla. There is a ‎risk that this and any other such facilities or loans may go into ‎default if there is a breach in complying ‎with covenants and obligations, which could result in the lenders realizing on their ‎security and causing ‎the shareholders to lose some or all of their investment.‎

- 33 -

Depending on Metalla's future business plans, Metalla may require additional debt financing that may not be available or, if available, may not be available on favourable terms. The level of Metalla's indebtedness from time to time could impair its ability to obtain additional financing on a timely basis to take advantage of business opportunities that may arise.

Litigation affecting Properties

Potential litigation may arise on a property on which Metalla holds or has a Royalty or Stream interest (for example, litigation ‎between joint venture partners or between operators and original property owners or neighbouring property owners). Metalla will not ‎generally have any influence on the litigation and will not generally have access to data. Any such litigation that results in the ‎cessation or reduction of production from a property (whether temporary or permanent) could have a material and adverse effect on ‎Metalla's profitability, results of operations, financial condition and the trading price of the Common Shares.‎

Application and Interpretation of Tax Laws

We are subject to direct and indirect taxes in various global jurisdictions. The amount of tax we pay, directly or indirectly, is subject to our interpretation of applicable tax laws in the jurisdictions in which we file, and the applicable tax laws in the jurisdictions of operations in which Metalla has interests including those from which we receive Royalties, Streams and other income.

We have taken and will continue to take tax positions based on our interpretation of tax laws, but tax accounting often involves complex matters and judgment is required in determining our worldwide provision for taxes and other tax liabilities. There can be no assurance that a taxing authority will not have a different interpretation of the law and assess us, or the operations in which Metalla has interests, with additional taxes.

While to our knowledge we are not currently the subject of any tax audits or under reassessment, tax authorities may in the future disagree with our judgment and the presentation of our tax position. We regularly assess the likely outcomes of tax audits or reassessments to determine the appropriateness of our tax liabilities. However, our judgment on tax matters might not be sustained as a result of audits or reassessments, and the amounts ultimately paid could be different from the amounts previously recorded or expected. In addition, our effective tax rate in the future could be adversely affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities and changes in tax laws. Tax rates in the jurisdictions in which we operate or in which we have interests may change as a result of macroeconomic, political or other factors. Increases in the tax rate in any of the jurisdictions in which Metalla has interests could have a negative impact on our profitability.

Changes in Tax Laws Impacting Metalla

There can be no assurance that new tax laws, regulations, policies or interpretations will not be enacted or brought into being in the ‎jurisdictions where Metalla has interests that could have a material adverse effect on Metalla. Any such change or implementation of ‎new tax laws or regulations could adversely affect Metalla's ability to conduct its business. No assurance can be given that new ‎taxation rules or accounting policies will not be enacted or that existing rules will not be applied in a manner which could result in the ‎profits of Metalla being subject to additional taxation or which could otherwise have a material adverse effect on the profitability of ‎Metalla, Metalla's results of operations, financial condition and the trading price of the Common Shares. In addition, the ‎introduction of new tax rules or accounting policies, or changes to, or differing interpretations of, or application of, existing tax rules ‎or accounting policies could make Royalties, Streams or other investments by Metalla less attractive to counterparties. Such changes ‎could adversely affect the ability of Metalla to acquire new assets or make future investments.

- 34 -

‎Anti-Bribery and Anti-Corruption Laws

Metalla is subject to certain anti-bribery and anti-corruption laws, including the Corruption of Foreign Public Officials Act (Canada) and the Foreign Corruption Practices Act (United States). Failure to comply with all such applicable laws could subject Metalla to, among other things, reputational damage, civil or criminal penalties, other remedial measures and legal expenses, which may have a material adverse effect on Metalla's business, results of operations and financial condition. It may not be possible for Metalla to ensure compliance with anti-bribery and anti-corruption laws in every jurisdiction to which it is subject.

In recent years, there has been a general increase in both the frequency of enforcement and the severity of penalties under anti-bribery and anti-corruption laws, resulting in greater scrutiny and punishment of companies convicted of violating such laws. Furthermore, a company may be found liable for violations by not only its employees, but also by its contractors and third-party agents. Metalla cannot guarantee that its employees, contractors, third-party agents and business partners have not in the past or will not in the future engage in such violations. If Metalla is the subject of an enforcement action or is otherwise in violation of such laws, it may result in significant penalties, fines and/or sanctions imposed on Metalla, which may have a material adverse effect on Metalla's business, results of operations and financial condition.

Credit and Liquidity Risk

Metalla is exposed to counterparty risks and liquidity risks including, but not limited to: (i) through the companies with which Metalla ‎has Streams and Royalty agreements with; (ii) through financial institutions that hold Metalla's cash and cash equivalents; ‎‎(iii) through companies that have payables to Metalla; (iv) through Metalla's insurance providers; and (v) through Metalla's lenders. ‎Metalla is also exposed to liquidity risks in meeting its operating expenditure requirements in instances where cash positions are ‎unable to be maintained or appropriate financing is unavailable. These factors may impact the ability of Metalla to obtain loans and ‎other credit facilities in the future and, if obtained, on terms favourable to Metalla. Also, if these risks materialize, the Company's ‎operations could be adversely impacted and the trading price of its securities could be adversely affected.‎

Information Systems and Cyber Security

Metalla's information systems, and those of its counterparties under the Streams and Royalties agreements and vendors, are ‎vulnerable to an increasing threat of continually evolving cybersecurity risks. Unauthorized parties may attempt to gain access to ‎these systems or Metalla's information through fraud or other means of deceiving Metalla's counterparties. Metalla's operations ‎depend, in part, on how well Metalla and its suppliers, as well as counterparties under the Streams and Royalties agreements, protect ‎networks, equipment, information technology systems and software against damage from a number of threats. The failure of ‎information systems or a component of information systems could, depending on the nature of any such failure, adversely impact ‎Metalla's reputation and results of operations. Although to date Metalla has not experienced any material losses relating to ‎cyber attacks or other information security breaches, there can be no assurance that Metalla will not incur such losses in the future. ‎Metalla's risk and exposure to these matters cannot be fully mitigated because of, among other things, the evolving nature of these ‎threats. As a result, cyber security and the continued development and enhancement of controls, processes and practices designed to ‎protect systems, computers, software, data and networks from attack, damage or unauthorized access remain an area of attention.

- 35 -

Activist Shareholders

Publicly traded companies are often subject to demands or publicity campaigns from activist shareholders advocating for changes to ‎corporate governance practices, such as executive compensation practices, social issues, or for certain corporate actions or ‎reorganizations. There can be no assurance that Metalla will not be subject to any such campaign, including proxy contests, media ‎campaigns or other activities. Responding to challenges from activist shareholders can be costly and time consuming and may have ‎an adverse effect on Metalla's reputation. In addition, responding to such campaigns would likely divert the attention and resources ‎of Metalla's management and board of directors, which could have an adverse effect on Metalla's business and results of operations. ‎Even if Metalla were to undertake changes or actions in response to activism, activist shareholders may continue to promote or ‎attempt to effect further changes and may attempt to acquire control of Metalla. If shareholder activists are ultimately elected to the ‎board of directors, this could adversely affect Metalla's business and future operations. This type of activism can also create ‎uncertainty about Metalla's future strategic direction, resulting in loss of future business opportunities, which could adversely affect ‎Metalla's business, future operations, profitability and Metalla's ability to attract and retain qualified personnel.‎

Reputational Damage

Reputational damage can be the result of the actual or perceived occurrence of any number of events, and could include any ‎negative publicity, whether true or not. While Metalla does not ultimately have direct control over how it is perceived by others, ‎reputational loss could have a material adverse impact on our financial performance, financial condition, cash flows and growth ‎prospects.‎

Expansion of Business Model

Metalla's operations and expertise have been focused on the acquisition and management of Royalty and Stream interests. Metalla ‎may pursue acquisitions outside this area, including acquiring and/or investing in and/or developing resource projects. Expansion of ‎Metalla's activities into new areas would present challenges and risks that it has not faced in the past, including many of the risks ‎described under the section Risks Related to Mines and Mining Operations. The failure to manage these challenges and risks ‎successfully may result in a material and adverse effect on Metalla's profitability, results of operations, financial condition and the ‎trading price of Metalla securities.‎

Risks Related to Mines and Mining Operations

Risk Factors applicable to Owners and Operators of Properties in which Metalla holds an Interest

To the extent that they relate to the production of minerals from or the continued operation of, properties in which Metalla holds a ‎Royalty or Stream interest, Metalla will be subject to the risk factors applicable to the owners and operators of such mines or projects.‎

Exploration, Development and Operating Risks

Mining involves a high degree of risk. Mines and projects in which Metalla has or may enter into a precious metal purchase ‎agreement or Royalty agreement are subject to all of the hazards and risks normally encountered in the exploration, development ‎and production of metals, including weather related events, unusual and unexpected geology formations, seismic activity, rock ‎bursts, cave ins, pit wall failures, flooding, environmental hazards and the discharge of toxic chemicals, explosions and other ‎conditions involved in the drilling, blasting and removal of material, any of which could result in damage to, or destruction of, mines ‎and other producing facilities, damage to property, injury or loss of life, environmental damage, work stoppages, delays in ‎production, increased production costs and possible legal liability. Any of these hazards and risks and other acts of God could shut ‎down Mining Operations temporarily or permanently. Mining Operations are subject to hazards such as equipment failure or failure ‎of retaining dams around tailings disposal areas which may result in environmental pollution and consequent liability for the owners ‎or operators of the Mining Operations.‎

- 36 -

The exploration for and development, mining and processing of mineral deposits involves significant risks which even a combination ‎of careful evaluation, experience and knowledge may not eliminate. While the discovery of an ore body may result in substantial ‎rewards, few properties which are explored are ultimately developed into producing mines. Major expenditures may be required to ‎locate and establish mineral reserves, to develop metallurgical processes and to construct mining and processing facilities at a ‎particular site. It is impossible to ensure that the exploration or development programs planned by the owners or operators of Mining ‎Operations will result in profitable commercial Mining Operations. Whether a mineral deposit will be commercially viable depends on ‎a number of factors, some of which are: cash costs associated with extraction and processing, the particular attributes of the deposit, ‎such as size, grade and proximity to infrastructure; metal prices which are highly cyclical; government regulations, including ‎regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of minerals and environmental ‎protection; and political stability. The exact effect of these factors cannot be accurately predicted, but the combination of these ‎factors may result in one or more of the Mining Operations not receiving an adequate return on invested capital. Accordingly there ‎can be no assurance the Mining Operations which are not currently in production will be brought into a state of commercial ‎production.‎

Climate Change

Governments are moving to introduce climate change legislation and treaties at the international, national, state/provincial and local levels. Regulation relating to emission levels (such as carbon taxes) and energy efficiency is becoming more stringent. The Paris climate accord was signed by 195 countries in December 2015 and marked a global shift toward a low-carbon economy.

If the current regulatory trend continues, Metalla expects that this will result in increased costs at some of the Mining Operations which could adversely impact the profitability or viability of such operations and may result in reduction or cessation of production which in turn would have an impact on the Company's revenue. In addition, the physical risks of climate change may also have an adverse effect on some of the Mining Operations. These risks include the following:

• sea level rise: changes in sea level could affect ocean transportation and shipping facilities which are used to transport supplies, equipment and workforce to some of the Mining Operations and products from those operations to world markets.

• extreme weather events: extreme weather events (such as increased frequency or intensity of hurricanes, increased snow pack, prolonged drought) have the potential to disrupt some of the Mining Operations. Extended disruptions to supply lines could result in interruption to production.

• resource shortages: some of the Mining Operations depend on regular supplies of consumables (diesel, tires, sodium cyanide, et cetera) and reagents to operate efficiently. In the event that the effects of climate change or extreme weather events cause prolonged disruption to the delivery of essential commodities, production efficiency at some of the Mining Operations is likely to be reduced.

There is no assurance that efforts to mitigate the risks of climate changes will be effective and that the physical risk of climate change will not have an adverse effect on the Mining Operations and their profitability.

Environmental Risks

All phases of mine operation or development are subject to governmental regulation including environmental regulation in the ‎various jurisdictions in which they operate. Environmental legislation is evolving in a manner which will require stricter standards and ‎enforcement, increased fines and penalties for non compliance, more stringent environmental assessments of proposed projects and ‎heightened responsibility for companies and their officers, directors and employees. There is no assurance that future changes in ‎environmental regulation, if any, will not adversely affect the mines and projects in which Metalla has an interest. Also, unknown ‎environmental hazards may exist on the properties at present which were caused by previous or existing owners or operators of the ‎properties and which could impair the commercial success, levels of production and continued feasibility and project development ‎and mining operations on these properties. One or more of the mining companies may become liable for such environmental hazards ‎caused by previous owners or operators of the properties.‎

- 37 -

Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions thereunder, ‎including orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective ‎measures requiring capital expenditures, installation of additional equipment or remedial actions. Parties engaged in mining ‎operations or in the exploration or development of mineral properties may be required to compensate those suffering loss or damage ‎by reason of the mining activities and may have civil or criminal fines or penalties imposed for violations of applicable laws or ‎regulations.‎

Government Regulation, Permits and Authorizations

The exploration and development activities related to mine operations are subject to extensive laws and regulations governing ‎exploration, development, production, exports, taxes, labour standards, waste disposal, protection and remediation of the ‎environment, reclamation, historic and cultural resources preservation, mine safety and occupational health, handling, storage and ‎transportation of hazardous substances and other matters.‎

The costs of discovering, evaluating, planning, designing, developing, constructing, operating and closing specific mine operations in ‎compliance with such laws and regulations are significant. It is possible that the costs and delays associated with compliance with ‎such laws and regulations could become such that the owners or operators of mines or projects would not proceed with the ‎development of, or continue to operate, a mine. Moreover, it is possible that future regulatory developments, such as increasingly ‎strict environmental protection laws, regulations and enforcement policies thereunder and claims for damages to property and ‎persons resulting from mining operations could result in substantial costs and liabilities for the owners or operators of mines or ‎projects in the future such that they would not proceed with the development of, or continue to operate, a mine.‎

Government approvals, licences and permits are currently, and will in the future be, required in connection with Mining Operations. To ‎the extent such approvals are required and not obtained, Mining Operations may be curtailed or prohibited from proceeding with ‎planned operations, which could have an impact on the business and financial condition of Metalla. Failure to comply with ‎applicable laws, regulations and permitting requirements may result in enforcement actions thereunder, including orders issued by ‎regulatory or judicial authorities causing operations to cease or be curtailed.‎

Amendments to current laws, regulations and permits governing operations and activities of mining companies, or more stringent ‎implementation thereof, could have a material adverse impact on Mining Operations, resulting in increased capital expenditures or ‎production costs, reduced levels of production at producing properties or abandonment or delays in development of properties.‎

Permitting and Access

The operation of a mine or project is subject to receipt and maintenance of permits from appropriate governmental authorities. The owners and operators of the mines and projects in which Metalla has an interest may be subject to delays in connection with obtaining access to the property and all necessary renewals of permits for existing operations, additional permits for any possible future changes to operations, or additional permits associated with new legislation. Prior to any development on any of the properties, permits from appropriate governmental authorities may be required. There can be no assurance that the owners or operators of the mines or projects will continue to hold all permits necessary to develop or continue operating at any particular property.

- 38 -

See "Risk Factors - Permitting, Construction and Development" for additional permitting risks associated with developmental projects.

Infrastructure

Natural resource exploration, development and mining activities are dependent on the availability of mining, drilling and related equipment in the particular areas where such activities are conducted. A limited supply of such equipment or access restrictions may affect the availability of such equipment to the owners and operators of mines or projects and may delay exploration, development or extraction activities. Certain equipment may not be immediately available or may require long lead time orders. The lack of availability on acceptable terms or the delay in the availability of any one or more of these items could prevent or delay exploration, development or production at a mine or project. Mining, processing, development and exploration activities depend, to one degree or another, on adequate infrastructure. Reliable roads, bridges, power sources and water supply are important determinants which affect capital and operating costs. Unusual or infrequent weather phenomena, sabotage, government or other interference in the maintenance or provision of such infrastructure could adversely affect operations at a mine or project.

Dependence on Operator's Employees

Production from the properties in which Metalla holds an interest depends on the efforts of operators' employees. There is competition for persons with mining expertise. The ability of the owners and operators of such properties to hire and retain geologists and persons with mining expertise is key to those operations. Further, relations with employees may be affected by changes in the scheme of labour relations that may be introduced by the relevant governmental authorities in the jurisdictions in which those operations are conducted. Changes in such legislation or otherwise in the relationships of the owners and operators of such properties with their employees may result in strikes, lockouts or other work stoppages, any of which could have a material adverse effect on such operations, results of operations and financial condition of Metalla. If these factors cause the owners and operators of such properties to decide to cease production at one or more of the properties, such decision could have a material adverse effect on the business and financial condition of Metalla.

Mineral Resource and Mineral Reserve Estimates

Mineral reserve and or mineral resource estimates for a specific mine or project may not be correct. The figures for mineral resources ‎and mineral reserves contained in this AIF are estimates only and ‎were obtained from public disclosure by the respective operators in respect of the Côté ‎Property, the Taca Taca Property and other properties, as ‎applicable. There can be no assurance that estimated mineral reserves and mineral resources will ever be recovered or recovered at ‎the rates as estimated. Mineral reserve and mineral resource estimates are based on sampling and geological interpretation, and, are ‎uncertain because samples used may not be representative. Mineral reserve and mineral resource estimates require revision (either to ‎demonstrate an increase or decrease) based on production from the mine or project. The fluctuations of commodity prices and ‎production costs, as well as changes in recovery rates, may render certain mineral reserves and mineral resources uneconomic and ‎may result in a restatement of estimated reserves and/or mineral resources.

Mineral resources that are not mineral reserves do not ‎have demonstrated economic viability. Due to the uncertainty of inferred mineral resources, there is no assurance that inferred ‎mineral resources will be upgraded to proven and probable mineral reserves as a result of continued exploration.‎

Depleted Mineral Reserve Replacement

Mines have a limited time of operation as a result of the proven and probable mineral reserves attributed to a specific mine. A mining ‎company operating a specific mine will be required to replace and expand mineral reserves depleted by a mine's production to ‎maintain production levels over a long term. It is possible to replace depleted mineral reserves by expanding known ore bodies ‎through exploration, locating new deposits or acquiring new mines or projects. Mineral exploration is highly speculative in nature. It ‎can take several years to develop a potential site of mineralization. There is no assurance that current or future exploration programs ‎conducted by mining companies will be successful. There is a risk that the depletion of mineral reserves by mining companies that ‎Metalla has contracted with will not be replenished by discoveries or acquisitions which could reduce the income Metalla would have ‎expected to receive from a particular Royalty or Stream.‎

- 39 -

Uninsured Risks

The mining industry is subject to significant risks that could result in damage to, or destruction of, mineral properties or producing facilities, personal injury or death, environmental damage, delays in mining, monetary losses and possible legal liability. Mining companies may or may not maintain insurance in adequate amounts, including insurance for workers' compensation, theft, general liability, all risk property, automobile, directors and officers liability and fiduciary liability and others. Such insurance, however, contains exclusions and limitations on coverage. Accordingly, a mining company's insurance policies may not provide coverage for all losses related to their business (and may not cover environmental liabilities and losses). The occurrence of losses, liabilities or damage not covered by such insurance policies could have a material adverse effect on the mining companies' profitability, results of operations and financial condition.

Land Title

Although title to specific mines or projects has been or will be reviewed by or on behalf of Metalla, no assurances can be given that there are no title defects affecting the properties and mineral claims owned or used by specific mines or projects. Companies may not have conducted surveys of the claims in which they hold direct or indirect interests; therefore, the precise area and location of such claims may be in doubt. It is possible that a specific mine or project may be subject to prior unregistered liens, agreements, transfers or claims, including native land claims, and title may be affected by, among other things, undetected defects. In addition, mining companies may be unable to operate the specific mine or project as permitted or to enforce their rights with respect to that specific mine or project which may ultimately impair the ability of these owners and operators to fulfill their obligations under their agreements with Metalla.

International Interests

Certain operations that underlie Metalla's Streams and Royalties are conducted, or will be conducted, outside of Canada, including in ‎Australia, the United States, Argentina, Mexico, Tanzania, Ecuador, Peru, Chile, Brazil and Venezuela and could be exposed to political, ‎economic or other risks or uncertainties. These types of risks or uncertainties may differ between countries and can include but are ‎not limited to, terrorism, hostage taking, military repression, crime, political instability, currency controls, fluctuations in currency ‎exchange rates, inflation rates, labour unrest, risk of war or civil unrest, expropriation and nationalization, renegotiation or ‎nullification of mining or mineral concessions, licenses, permits, authorizations and contracts, illegal mining or mineral exploration, ‎taxation changes, modifications, amendments or changes to mining and mineral laws, regulations, policies, and changes to ‎government regulations in respect of foreign investment and mining.‎

Changes, if any, in mining or investment policies or shifts in political attitude may adversely affect the operations or profitability of ‎the Mining Operations in these countries. Operations may be affected in varying degrees by government regulations with respect to, ‎but not limited to, restrictions on production, price controls, export controls, currency remittance, income taxes, expropriation of ‎property, foreign investment, maintenance of claims, environmental legislation, land use, land claims of local people, water use, mine ‎safety and the rewarding of contracts to local contractors or requiring foreign contractors to employ citizens of, or purchase supplies ‎from, a particular jurisdiction or the imposition of additional local or foreign parties as joint venture partners with carried or other ‎interests. Failure to comply strictly with applicable laws, regulations and local practices relating to mineral right applications and ‎tenure, could result in loss, reduction or expropriation, cancellation or dispute of licenses or entitlements which could result in ‎substantial costs, losses and liabilities in the future. ‎

- 40 -

The occurrence of these various factors and uncertainties related to the economic and political risks for operations in foreign ‎jurisdictions cannot be accurately predicted and could have an adverse effect on the Mining Operations resulting in substantial costs, ‎losses and liabilities in the future.‎

Developing Economies

Certain operators are subject to risks normally associated with the conduct of business in developing economies. Risks may include, among others, problems relating to power supply, labour disputes, delays or invalidation of governmental orders and permits, corruption, uncertain political and economic environments, civil disturbances and crime, arbitrary changes in laws or policies, foreign taxation and exchange controls, nationalization of assets, opposition to mining from environmental or other non-governmental organizations or changes in the political attitude towards mining, empowerment of previously disadvantaged people, local ownership requirements, limitations on foreign ownership, power supply issues, limitations on repatriation of earnings, infrastructure limitations and increased financing costs. The above risks may limit, disrupt or negatively impact the operator's business activities.

Permitting, Construction and Development

Metalla may hold Royalties or Streams over mines and projects that may be in various stages of permitting, construction, development and expansion. Construction, development and expansion of such mines or projects is subject to numerous risks, including, but not limited to: delays in obtaining equipment, materials, and services essential to completing construction of such projects in a timely manner; delays or inability to obtain all required permits; changes in environmental or other government regulations; currency exchange rates; labour shortages; and fluctuation in metal prices. There can be no assurance that the owners or operators of such mines or projects will have the financial, technical and operational resources to complete the permitting, construction, development and expansion of such mines or projects in accordance with current expectations or at all.

Indigenous Peoples

Various international and national laws, codes, resolutions, conventions, guidelines, and other materials relate to the rights of indigenous peoples. Metalla holds Royalty or Stream interests on operations located in some areas presently or previously inhabited or used by indigenous peoples. Many of these materials impose obligations on government to respect the rights of indigenous people. Some mandate that government consult with indigenous people regarding government actions which may affect indigenous people, including actions to approve or grant mining rights or permits. The obligations of government and private parties under the various international and national materials pertaining to indigenous people continue to evolve and be defined. The mining companies' current or future operations are subject to a risk that one or more groups of indigenous people may oppose continued operation, further development, or new development on those projects or operations on which Metalla holds a Royalty or Stream interest. Such opposition may be directed through legal or administrative proceedings or protests, roadblocks or other forms of public expression against the Company or the owner/operators' activities. Opposition by indigenous people to such activities may require modification of or preclude operation or development of projects or may require the entering into of agreements with indigenous people. Claims and protests of indigenous people may disrupt or delay activities of the owners/operators of Metalla's Royalty or Stream assets.

Nominal Third-Party Interests in Subsidiaries

In certain jurisdictions in which we operate, including Australia, Argentina and Mexico, laws require that ‎our subsidiaries in those jurisdictions have more than one shareholder. In such jurisdictions, a nominal ‎interest may be held by an individual or an affiliate of Metalla which is not represented on organization ‎charts or other disclosure in this AIF.‎

- 41 -

Risks Related to the Securities of Metalla

Securities of Metalla are subject to Price Volatility

Capital and securities markets have a high level of price and volume volatility, and the market price of securities of many companies ‎have experienced wide fluctuations in price which have not necessarily been related to the operating performance, underlying asset ‎values or prospects of such companies. Factors unrelated to the financial performance or prospects of Metalla include ‎macroeconomic developments in North America and globally, and market perceptions of the attractiveness of particular industries or ‎asset classes. There can be no assurance that continued fluctuations in mineral or commodity prices will not occur. As a result of any ‎of these factors, the market price of the Common Shares at any given time may not accurately reflect the long-term value ‎of Metalla.‎

In the past, following periods of volatility in the market price of a company's securities, shareholders have instituted class action ‎securities litigation against them. Such litigation, if instituted, could result in substantial cost and diversion of management attention ‎and resources, which could significantly harm profitability and the reputation of Metalla.‎

Dilution

Metalla may issue additional securities in the future in connection with acquisitions, strategic transactions, debt repayment, financings or for other ‎purposes. To the extent additional securities are issued, Metalla's existing securityholders could be diluted and some or all of ‎Metalla's financial measures could be reduced on a per share basis. Additionally, Metalla securities issued in connection with a ‎transaction may not be subject to resale restrictions and, as such, the market price of Metalla's securities may decline if certain large ‎holders of Metalla securities or recipients of Metalla securities in connection with an acquisition, sell all or a significant portion of such ‎securities or are perceived by the market as intending to sell such securities. In addition, such issuances of securities may impede ‎Metalla's ability to raise capital through the sale of additional equity securities in the future.‎

Evolving Corporate Governance and Public Disclosure Regulations

Metalla is subject to changing rules and regulations promulgated by a number of United States and Canadian governmental and ‎self regulated organizations, including the SEC, the Canadian Securities ‎Administrators, the exchanges listing Metalla's securities, and the Financial Accounting Standards Board. These rules and regulations ‎continue to evolve in scope and complexity making compliance more difficult and uncertain. Metalla's efforts to comply with these ‎and other new and existing rules and regulations have resulted in, and are likely to continue to result in, increased general and ‎administrative expenses and a diversion of management time and attention from revenue generating activities to compliance ‎activities.‎

Future Sales or Issuances of Debt or Equity Securities ‎

We may sell or issue additional debt or equity securities in offerings to finance our operations, exploration, ‎development, acquisitions, debt repayment or other projects. Our significant shareholders may also sell the Common Shares or other ‎securities they hold or may hold in the future.‎

We cannot predict the size of future sales and issuances of debt or equity securities or the effect, if any, that future ‎sales and issuances of debt or equity securities will have on the market price of the Common Shares.‎

Sales or issuances of a substantial number of equity securities, or the perception that such sales could occur, may ‎adversely affect prevailing market prices for the Company's Common Shares. With any additional sale or issuance ‎of equity securities, investors will suffer dilution of their voting power and may experience dilution in the ‎Company's earnings per share. Sales of our Common Shares by shareholders might also make it more difficult for ‎us to sell equity securities at a time and price that we deem appropriate.‎

- 42 -

Liquidity

Shareholders of the Company may be unable to sell significant quantities of Common Shares into the public ‎trading markets without a significant reduction in the price of their Common Shares, or at all. There can be no ‎assurance that there will be sufficient liquidity of the Company's Common Shares on the trading market, and that ‎the Company will continue to meet the listing requirements of the TSXV, the NYSE or the Frankfurt ‎Exchange, or achieve listing on any other public listing exchange.‎

Market for Securities

There can be no assurance that an active trading market for the Common Shares will be sustained.‎

Limitations on the Enforcement of Civil Judgments

A substantial portion of the assets of Metalla are located outside of Canada. As a result, it may not be possible for ‎investors in the securities of Metalla to collect on judgments obtained in courts in Canada predicated on the civil ‎liability provisions of securities legislation of certain of the provinces and territories of Canada.‎

It may also be difficult to bring and enforce suits against us in the United States, because we exist under the laws of ‎British Columbia and are situated in the Province of British Columbia, Canada and most of our assets are located ‎outside the United States. ‎

It may be difficult for investors to effect service of process on us or our directors or officers or to realize in the ‎United States upon judgments obtained in the United States based on the civil liability provisions of the U.S. federal ‎securities laws. In addition, our U.S. shareholders should not assume that the courts of Canada (i) would enforce ‎judgments of U.S. courts obtained in actions against us, our officers or directors predicated upon the civil liability ‎provisions of the U.S. federal securities laws or other laws of the United States, or (ii) would enforce, in original ‎actions, liabilities against us, our officers or directors predicated upon the U.S. federal securities laws or other laws of ‎the United States.‎

U.S. Tax Risk Related to Potential Passive Foreign Investment Company Status

If we are a "passive foreign investment company" ("PFIC") for the current or a future tax year, certain adverse ‎U.S. federal income tax consequences may result for U.S. investors.‎

In general, we will be treated as a PFIC for any tax year during which either (i) 75% or more of our gross income is ‎passive income, or (ii) 50% or more of the average quarterly value of our assets that produce or are held for the ‎production of passive income. The determination of PFIC status is inherently factual, is subject to a number of ‎uncertainties, and can be determined only annually at the close of the tax year in question. Although the Company ‎has not made a formal determination as to whether it was a PFIC for the year ended December 31, 2023, and does ‎not plan to make such a determination for subsequent years, the Company believes there is a significant risk that it ‎was a PFIC for the year ended December 31, 2023, and anticipates that there will be a significant risk that it will be a ‎PFIC in subsequent years.‎

If we are a PFIC for any year during a U.S. taxpayer's holding period of Common Shares, then such U.S. ‎taxpayer generally will be required to treat any gain realized upon a disposition of the Common Shares or any ‎so-called "excess distribution" received on its Common Shares, as ordinary income, and to pay an interest ‎charge on a portion of such gain or distribution. In certain circumstances, the sum of the tax and the interest ‎charge may exceed the total amount of proceeds realized on the disposition, or the amount of excess ‎distribution received, by the U.S. taxpayer. Subject to certain limitations, these tax consequences may be ‎mitigated if a U.S. taxpayer makes a timely and effective "qualified electing fund" election ("QEF Election") ‎or a "mark-to-market" election ("Mark-to-Market Election"). Subject to certain limitations, such elections ‎may be made with respect to the Common Shares. A U.S. taxpayer who makes a timely and effective QEF ‎Election generally must report on a current basis its share of our net capital gain and ordinary earnings for ‎any year in which we are a PFIC, whether or not we distribute any amounts to its shareholders. Upon the written request of a U.S. shareholder, the Company will make publicly available: (a) a "PFIC Annual Information Statement" as described in Treasury Regulations section 1.1295-1(g) (or any successor Treasury Regulation) and (b) all information and documentation that a U.S. shareholder is required to obtain for U.S. federal income tax purposes in making a QEF Election with respect to the Company. A U.S. taxpayer who makes the Mark-to-Market Election generally must include as ‎ordinary income each year the excess of the fair market value of the Common Shares over the taxpayer's basis ‎therein. The PFIC rules may also apply to other securities issued by us. Each potential investor who is a U.S. taxpayer should consult its ‎own tax advisor regarding the tax consequences of the PFIC rules and the acquisition, ownership, and ‎disposition of the Common Shares or other securities issued by us.‎

Summary

Property Description, Location and Access

The Côté Gold Project is located in the Porcupine Mining Division, 20 km southwest of Gogama, Ontario and extends approximately 73 km from Esther Township in the west to Garibaldi Township in the east. The Côté Gold Project comprises a group of properties assembled through staking and option agreements covering a total area of approximately 596 km². The Côté Gold Project mining leases area forms a portion of the overall claim area.

The Côté Gold Project is bisected by Highway 144 and is approximately 175 km north of Sudbury via Highway 144 and 125 km southwest of Timmins via Highways 101 and 144.

The original Chester exploration property is located in the central portion of the mining leases area, which hosts the Côté and Gosselin deposits, as well as the Chester 1 zone and several other gold occurrences. IAMGOLD holds a significant land package which adequately covers the Côté Gold Project and area outside the Côté Gold Project mining leases. Overall, the Côté Gold Project's property package consists of 2,976 tenures covering a surface area of approximately 59,591 ha (or 595.91 km²).

On December 19, 2022, IAMGOLD announced that it had reached an agreement to further amend the amended and restated joint venture agreement with Sumitomo Metal Mining Co., Ltd. ("SMM"). Commencing in January 2023, SMM contributed $250 million of IAMGOLD's funding amounts to the Côté Gold Project. As a result of SMM funding such amounts, IAMGOLD transferred, in aggregate, a 9.7% interest in Côté to SMM as funding is made by SMM, subject to the right for IAMGOLD to repurchase the transferred interests to return to its full 70% interest in the Côté Gold Project.

- 45 -

IAMGOLD to the right to repurchase such transferred interests pursuant to the terms of the agreement. IAMGOLD agreed to pay a repurchase option fee to SMM on the terms set forth in the agreement, and IAMGOLD has the right to exercise its right to repurchase the transferred 9.7% interest on seven dates between November 30, 2023, and November 30, 2026, to return to its full 70% interest in the Côté Gold Project. IAMGOLD may exercise its option through the payment of the initial $250 million plus the aggregate amounts advanced by SMM in respect of the transferred 9.7% interest, subject to certain adjustments as set out in the amending agreement relating to the period between initial gold production and commercial production.

Please see Section 4 of the Côté Gold Report for a detailed description of the terms of any royalties and other agreements to which the Côté Gold Project is subject, as well as the tenure and expiration dates of the claims, licenses and other property tenure rights.

IAMGOLD is not aware of any environmental liabilities associated with or attributable to any of the subject property groups in the ‎Côté Gold Project area, other than those that would normally be expected as a result of historical mining ‎activities and associated mine workings‎.

Legacy diamond drill site remediation took place from 2013 to 2018 with 186 legacy drill sites remediated. This work comprised removal of historic debris, capping of drill casings, and attaching a marker flag to the casing.

A program of drill collar decommissioning took place between 2019 and 2020 in areas of planned Côté Gold Project infrastructure. These drill holes were grouted to prevent ground water flow and the casings were removed.

IAMGOLD is not aware of any other risks that could affect access, title or its ownership interests in, or ‎the right or ability to perform work on the Côté Gold Project.‎

History

Prospecting and exploration activity in the Côté Gold Project area began circa 1900 and has continued sporadically to the present, spurred on periodically from exploration in the Porcupine and Elk Lake- Gowganda-Shiningtree camps. The first discovery of note was the Lawrence copper prospect on the east shore of Mesomikenda Lake in 1910. Further interest in the area was sparked in 1930 when Alfred Gosselin found outcropping gold mineralization on the east shore of Three Duck Lakes.

Historical work on the Côté Gold Project's property package has been conducted in multiple stages:

• In the early 1940s extensive prospecting and trenching was conducted, in addition to the sinking of several shallow shafts and some minor production.

• Through to the late 1960s little or no work was performed.

• From the early 1970s to approximately 1990, extensive surface work was performed, in addition to some limited underground investigations.

• From 1990 to 2009, fragmented property ownership precluded any major programs.

• In 2009, a group of properties that became the Chester property was consolidated by Trelawney.

A significant number of gold showings have been discovered on the Côté Gold Project's property package. Please see Section 6 of the Côté Gold Report for a detailed description of the history of the exploration and development at the Côté Gold Project.

Geological Setting, Mineralization and Deposit Types

- 46 -

The Côté and Gosselin deposits are located in the Swayze greenstone belt in the southwestern extension of the Abitibi greenstone belt of the Superior Province. The Abitibi Subprovince comprises Late Archean metavolcanic rocks, related synvolcanic intrusions, and clastic metasedimentary rocks, intruded by Archean alkaline intrusions and Paleoproterozoic diabase dykes. The traditional Abitibi greenstone belt stratigraphic model envisages lithostratigraphic units deposited in autochthonous successions, with their current complex map pattern distribution developed through the interplay of multiphase folding and faulting. The Swayze greenstone belt, like the rest of the Abitibi greenstone belt, contains extrusive and intrusive rock types ranging from ultramafic through felsic in composition, as well as both chemical and clastic sedimentary rocks. All of the rock types within the Swayze belt are older than 2,680 Ma, with the oldest dating 2,748.2 Ma. Igneous lithologies predominate and include both volcanic and plutonic rocks. The latter are observed both internally in the supracrustal belts and externally, in large granitoid complexes. Sedimentary rocks occur predominantly near the top of the succession.

The Swayze greenstone belt underwent a complex and protracted structural history of polyphase folding, development of multiple foliations, ductile high strain zones, and late brittle faulting. The map pattern preserved within the Swayze greenstone belt is dominated by regional F2 folding, and anticlines and synclines with an associated S2 axial-planar foliation interpreted to have formed during orogen-wide shortening across the entire Superior Province. An important structural element is the Ridout Deformation Zone ("RDZ"), a major east-west high strain zone that is interpreted to be the western extension of the Larder Lake-Cadillac deformation zone of the Abitibi greenstone belt. The F2 Ridout Synform coincides with the RDZ wherein intense deformation is characterized by intense flattening, tight to isoclinal folding, transposition, and locally a component of dextral simple shear in east-southeast-striking zones. Metamorphic grade within the southern Abitibi greenstone belt ranges from sub-greenschist to greenschist.

The Côté and Gosselin deposits are situated within the Chester Township area, which overlies a narrow greenstone belt assemblage that extends easterly from the southeast corner of the Swayze greenstone belt to the Shining Tree area, approximately 60 km to the east. The greenstone (supracrustal) assemblage is part of the well-defined Ridout syncline that separates the Kenogamissi granitoid complex to the north from the Ramsey-Algoma granitoid complex to the south. The Kenogamissi complex, yielding ages of 2,747 Ma, consists of sheet-like dioritic and tonalitic intrusions, which are interpreted locally to be synvolcanic. The Chester Intrusive Complex ("CIC"), which hosts the Côté and Gosselin deposits, is also synvolcanic and was emplaced along what is now the southern margin of the Ridout syncline. The CIC is a crudely stratified tonalite-diorite-quartz diorite laccolith containing numerous screens and inclusions of mafic volcanic rocks.

The Côté and Gosselin deposits are located with 1.5 km of each other and are both hosted by the CIC. The deposits are similar in geological composition with a few key differences in terms of breccia rocks and alteration. Both deposits are centred on magmatic and hydrothermal breccia bodies that intrude tonalitic and dioritic rocks. The CIC intruded into the mafic volcanic rocks of the Arbutus Formation, which forms the basal formation in the Chester Group. The formation consists of low potassium tholeiitic pillow basalts, mafic flows, and sills. The intrusive host rocks formed from a number of pulses of several distinct and evolving dioritic and tonalitic magmas that display complex crosscutting relationships.

The Côté and Gosselin deposit type gold mineralization consists of low to moderate grade gold (±copper) mineralization associated with brecciated and altered tonalite and diorite rocks.

Several styles of gold mineralization are recognized within the deposit, and include disseminated, breccia hosted and vein type, all of which are co-spatial with biotite (± chlorite), sericite and for the Côté deposit silica-sodic alteration.

Disseminated mineralization in the hydrothermal matrix of the breccia is the most important style of gold (±copper) mineralization. This style consists of disseminated pyrite, chalcopyrite, pyrrhotite, magnetite, gold (often in native form), and molybdenite in the matrix of the breccia and is associated with primary hydrothermal biotite and chlorite after biotite.

- 47 -

Other mineralization styles that have been identified within the Côté Gold Project area include orogenic or structurally-hosted vein occurrences, and syenite intrusion-related gold zones. The syenite intrusion-related gold zones are considered attractive exploration targets.

The Côté Gold Project deposit is a new Archean low-grade, high tonnage gold (± copper) discovery. It is described as a synvolcanic intrusion related and stockwork disseminated gold deposit. Deposits of this type are commonly spatially associated with and/or hosted in intrusive rocks. They include porphyry copper-gold, syenite associated disseminated gold and reduced gold-bismuth-tellurium-tungsten intrusion related deposits, as well as stockwork disseminated gold.

Certain features of the Côté deposit resemble those characteristics of gold rich porphyry deposits. These include:

• Emplacement at shallow (one to two kilometres) crustal levels, frequently associated with coeval volcanic rocks.

• Localized by major fault zones, although many deposits show only relatively minor structures in their immediate vicinities.

• Hydrothermal breccias are commonly associated with the deposits and consist of early orthomagmatic as well as later phreatic and phreatomagmatic breccias.

• Gold is fine grained, commonly <20 micrometres, generally <100 micrometres, and is closely associated with iron and copper-iron sulphides (pyrite, bornite, chalcopyrite).

The Gosselin deposit, similar to the Côté deposit, is also hosted in the synvolcanic CIC and most of its mineralization lies within hydrothermal breccia, diorite breccia, and tonalite units. Both the Gosselin deposit and the Côté deposit are classified as intrusion related disseminated gold deposits. Preliminary investigations completed on host breccias of the Côté deposit and the Gosselin deposit reveal that the Gosselin breccias resulted from fracturing and infiltration of fluids via fractures and veins. It is postulated that the combination of fracturing and fluid infiltration resulted in intense alteration through extensive fluid wall rock interaction, resulting in the formation of the breccia type appearance. Observations from the Gosselin deposit drill core reveal a spatial distribution of gold grades with increasing sericite alteration and associated with narrow quartz-carbonate-biotite-chlorite-pyrrhotite ± pyrite±chalcopyrite veins. Further work is planned to assess the detailed mineralogy and petrogenesis of the Gosselin deposit.

Exploration

The Côté Gold Project area is divided into three sectors for exploration purposes: (i) South Swayze West (western area), (ii) Chester (central area), and (iii) South Swayze East (eastern area). Exploration programs to date have identified the Côté and the Gosselin deposits and have evaluated several nearby gold showings for their potential to be bulk-mineable gold deposits. Gold zones situated near the Côté and Gosselin deposits remain prospective for additional bulk-tonnage gold mineralization, and active exploration programs will continue to evaluate these targets.

Exploration programs to date have been sufficient to screen many areas for the presence of a Côté-style deposit, with grid line spacing and general traverse spacing of <200 metres (some areas <100 metres spacing for traverse/grid line density). Litho-sampling and geological mapping is representative over much of the land holdings within the Côté Gold Project, with some exceptions where glacial till and lacustrine deposits form thick mantels on the bedrock. In areas of thick overburden, IP geophysical surveys and diamond drilling has helped screen these areas.

General results and conclusions from ongoing exploration work are summarized below by target area:

- 48 -

• South Swayze West: Côté-style tonalite and diorite hosted breccia zones have not been discovered to date. Exploration for syenite intrusion or shear zone hosted gold zones continues. The presence of Timiskaming-style basin sediments cut by porphyry intrusions and broad structural deformation zones provide a good environment for gold bearing vein networks.

• Chester Area: Southwest of the Côté deposit, gold mineralization was discovered in the Clam Lake area within ‎similar host rocks and alteration styles to the Côté deposit. Sheeted sulphide veins have been ‎mapped along the shoreline of Clam Lake and more recent regional exploration drilling ‎intersected these same vein types hosted within strongly-altered tonalite. The area is ‎considered to be highly prospective for gold mineralization. Northeast of the Gosselin deposit, ‎gold mineralization occurs in narrow shear zones hosted in diorite and tonalite in the Jack ‎Rabbit area, which also remains prospective for economic gold accumulations‎.

• South Swayze East: Gold mineralization discovered and investigated to date reveals only narrow and discontinuous shear zone hosted veins. The lack of Côté-style mineralization makes this area less favorable for the discovery of a bulk-tonnage gold zone.

Drilling

Côté

Core drilling of the Côté deposit commenced in 2009 and has included various phases of exploration, infill, metallurgical and condemnation drilling. A total of 808 drill holes (327,433 metres) have been completed within the Côté Gold Project deposit area.

Core sizes have included the following: HQ (63.5-millimetre core diameter), NQ (47.6 millimetres), BQ (36.4 millimetres), and BQTW (36 millimetres). For holes drilled on land, the casing was left in place and capped. Holes drilled on lakes were cemented and the casing pulled.

Geologists checked all core boxes upon arrival at the core shack and ensured that no core was missing and any reported drill hole orientation information was provided from the drilling contractor. Technicians made meterage marks and logged rock quality designation (RQD). All core was photographed.

Geologists completed the core log, recording details of lithology, alteration, mineralization, and structure. The Côté database has core recovery measurements for 179 Trelawney drill holes and 423 IAMGOLD drill holes. Overall, the core recovery from the 2009 to 2019 programs was approximately 99%.

For oriented core, technicians drew the bottom of hole line on the core. A full line was drawn when orientation marks were perfectly aligned. Alpha and beta angles were measured for all veins and contacts when the bottom of the hole line was defined.

The collar azimuths for pre-2017 holes were established using front and back site markers located in the field with compass or GPS instruments. The collars are subsequently re-surveyed post-drilling. L. Labelle Surveys based in Timmins, Ontario has been responsible for collecting the survey measurements for Côté since 2009.

A FlexIT SmartTool instrument was used to collect down hole survey measurements for key index holes drilled between 2009 and 2013. A Reflex EZ-TRAC tool was used to collect down hole survey measurements for holes drilled between 2014 and 2019.

Drilling at Côté is typically oriented perpendicular to the strike of the mineralization. Depending on the dip of the drill hole and the dip of the mineralization, drill intercept widths are typically greater than true widths.

Gosselin

- 49 -

Exploratory diamond drilling at Gosselin was initiated in 2016 and following completion of five drill holes (2016 to 2017) resulted in a significant new discovery. Following the initial drilling period, successive drilling campaigns from 2018 to 2022 have been completed to delineate the Gosselin Mineral Resource and to complete the required in-fill drilling to support an initial Mineral Resource estimate.

Since completion of the initial Gosselin Mineral Resource estimate (effective October 4, 2021), IAMGOLD ‎has been conducting drilling programs focused on evaluating the saddle area between the Côté and ‎Gosselin resource pit shells and testing for extensions of mineralization along strike and at depth below ‎the current Gosselin resource pit shell. A total of 18,809 metres (37 holes) have been completed ‎between July 29, 2021 and November 13, 2022 and results reported by IAMGOLD. To further test the expansion ‎opportunity of the Gosselin Resource, an additional twenty-one (21) diamond drill holes totaling 16,554 ‎metres were completed between January 20 and August 24, 2023. IAMGOLD has indicated that the results are to be incorporated into ‎the Gosselin deposit model for use in future Mineral Resource estimation updates.‎

A total of 152 drill holes (73,761 metres) have been completed within the Gosselin deposit area. Land ‎and ice- based drill holes were NQ core size (47.6-millimetre core diameter), whereas barge-based drill ‎holes were BTW core size (42-millimetre core diameter). Drill rigs employed wireline systems and ‎generally oriented-core drilling techniques. For holes drilled on land, the casing was left in place and ‎capped. Holes drilled on lakes were cemented and the casing pulled.

Geologists checked all core boxes upon arrival at the core shack and ensured that no core was missing and any reported drill hole orientation information was provided from the drilling contractor. Technicians made meterage marks and logged RQD. All core was photographed.

Geologists completed the core log, recording details of lithology, alteration, mineralization, and structure. For oriented core, technicians drew the bottom of hole line on the core. A full line was drawn when orientation marks were perfectly aligned. Alpha and beta angles were measured for all veins and contacts when the bottom of hole line was defined.

The Gosselin database has core recovery measurements for all 152 IAMGOLD drill holes. IAMGOLD core recovery is generally excellent with an average recovery of 99.5%.

Both land and ice-based drill hole collars were initially positioned using a handheld Garmin 64s GPS with ± three metre accuracy. Prior to drilling on ice and barge-based platforms, Tulloch Geomatics was contracted to further correct the final collar locations using a Trimble R10 GPS receiver in Real Time Kinematic mode (vertical and horizontal accuracy of ± 0.03 metres). Land-based drill hole collars were surveyed by Tulloch Geomatics once drilling was completed.

On land and ice-based drill platforms, the collar azimuths were initially established by IAMGOLD geologists using front and back sight markers with a compass, then further refined with a Reflex North Finder APS (Azimuth Pointing System) tool. The Reflex APS is a GPS based tool that is not affected by local magnetic interference. On barge-based platforms, Tulloch Geomatics was contracted to mark the initial collar locations by placing marker buoys positioned with a Trimble R10 GPS receiver in Real Time Kinematic mode. Reflex APS was used to align the collar azimuths.

A Reflex EZ-TRAC tool was used to collect down hole survey measurements for holes drilled between 2018 and 2022.

The Gosselin deposit mineralization orientation varies in strike and dip locally. Actual core widths are estimated at approximately 60% to 95% of the core interval.

Regional Exploration Drilling

- 50 -

Outside the Côté Gold Project deposit area and the Gosselin deposit area, regional diamond drilling in the period 2009-2022 comprised a total of 560 drill holes for about 155,769 metres. Diamond drilling methods employed during regional exploration drilling programs were very similar to methods used during Côté and Gosselin drilling. Programs generally employed the following methods:

• Drill core diameters were NQ (core diameter 47 millimetres) and BQTW (core diameter 42 millimetres).

• Drills employed wireline set-ups and employed stabilization equipment such as hexagonal core barrels and long remaining shells.

• Alignment of drill rigs was completed by compass sighting, Azimuth Pointing Equipment, and rarely gyro-compass.

• For those programs that utilized drill core orientation methodology, the Reflex ACT III System was used.

• Drill collars were generally left in place following drilling and marked with casing caps and flags.

• Any drill collars in proximity to planned infrastructure were marked with wooden monuments, for easy identification should grouting be required.

All drill holes completed on ice or water bodies by barge were cemented and the casings pulled.

Sampling, Analysis and Data Verification

1.Sampling and Analysis

The Côté and Gosselin sampling intervals were established by reviewing the minimum and maximum sampling lengths based on geological and/or structural criteria. The minimum sampling length was 50 centimetres, while the maximum was 1.5 metres. The typical sample length in most of the mineralized zones is one metre.

From 2009 to 2012, density measurements for the Côté deposit were obtained using the immersion method. For 2014 and 2015, density was measured on pulps at ActLabs using a pycnometer. In 2018, additional measurements by water immersion and a comparison between the historical pycnometer and water immersion methods was completed to validate the optimum method. Lacquer sealed and uncoated water immersion pair measurements were also completed in 2018.

Côté

Sample preparation and analysis at Accurassay comprised the following procedures:

• Samples were crushed to -8 mesh after which a 1,000 gram subset of each sample was pulverized to 90% passing -150 mesh.
• Assays were completed using a standard FA with a 30 gram aliquot and an AA finish.
• For samples that returned values of 2 g/t Au to 5 g/t Au, another pulp was taken, and FA-gravimetric finish.
• Samples returning values >5 g/t Au were reanalyzed by pulp metallic analysis.
• All samples were subject to a 33 element inductively coupled plasma (ICP) scan, using Accurassay procedure ICP 580.

Sample preparation and analysis at ActLabs until 2017 comprised the following procedures:

• Samples were crushed to 10 mesh after which a 1,000 gram subset of each sample was pulverized to 85% passing 200 mesh.

• Assays were completed using a standard FA with a 30 gram aliquot and an AA finish.

• For samples that return values between 2 g/t Au to 5 g/t Au, another pulp was taken and assayed using the FA-gravimetric method.

• Samples returning values >5 g/t Au were reanalyzed by pulp screen metallic analysis.

In 2017, the ActLabs procedure changed and included:

- 52 -

• Sample preparation consisted of coarse crushing to 95% passing 2.8-millimetre screen (7 mesh screen), and then a 750 gram to 850 gram split was pulverized to 95% passing 100 mesh (150 micrometres). The entire sample had to be crushed.

• Samples were analyzed using a standard 50 grams FA (50 gram aliquot) with an AA finish.

• For samples that returned assay values >2.0 g/t Au, another cut was taken from the original pulp and subjected to FA-gravimetric analysis.

• For samples displaying VG or samples which returned values >20.0 g/t Au, a reanalysis using pulp metallic methods was undertaken. A second pulp (900 grams to 1,000 grams) was created from the reject. However, flagged VG samples still underwent the entire assay process.

Umpire analysis at ALS and AGAT consisted of:

• Initial analysis using the FA-AA method.

• Overlimit assays using the FA-gravimetric method.

QA/QC insertion included SRMs, blanks and pulp duplicates as a standard procedure. IAMGOLD inserted control samples after every 12th sample interval. Over the Côté Gold Project life, about 23 different SRMs and two types of blanks have been used. The IAMGOLD QA/QC protocol includes the use of blanks inserted in the sample stream at a frequency of approximately one in 24 samples.

Gosselin

Sample preparation and analysis at ActLabs consisted of:

• Samples were coarse crushed to 80% passing 2.0-millimetre screen (10 mesh screen), riffle split (250 grams) and (mild steel) to 95% passing 105 micrometres.

• Assays were completed using a standard FA with a 30 gram aliquot and AA finish.

• For samples that returned assay values over 3.0 g/t Au, another cut was taken from the original pulp and FA-gravimetric finish.

• For samples displaying VG or samples that returned values greater than 5.0 g/t Au, these were reanalyzed by pulp metallic analysis.

• IAMGOLD inserts blanks and certified reference standards in the sample sequence for QC.

The QC protocol used during the Gosselin drilling program includes the insertion of SRMs and blanks at a rate of 1 in 12 samples each. This has amounted to a total of 3,746 QC sample insertions, including 1,755 SRMs and 1,991 blanks. This is a sufficient level of coverage, 3.8% and 4.3% respectively, to ensure the accuracy of all assay fusion batches. In addition, the remaining half of the cut core of every 20th sample was collected as a core duplicate starting at drill hole GOS19-30. This provided a total of 1,320 duplicate matched-pair assays, which is sufficient for precision evaluation.

2.Sampling Storage and Security

For Côté, pre-2017 drill hole data previously stored in a GEMS database was moved to acQuire. All new drill hole collars are provided by surveyors and imported into GEMS and subsequently transferred to acQuire. All new logging is recorded directly into a GEMS database and subsequently transferred to acQuire. All new assay results are imported directly into acQuire and subsequently transferred to the GEMS database. For Gosselin, MS Access is used with custom forms and queries for data input and management.

- 53 -

Analytical samples are transported by IAMGOLD or laboratory personnel using corporately owned vehicles. Core boxes and samples are stored in safe, controlled areas. Chain of custody procedures are followed whenever samples are moved between locations, to and from the laboratory, by filling out sample submittal forms.

Drill core is stored on the Côté Gold Project property in wooden core boxes under open sided roofed structures, arranged by year. A map of the core shack is available on site. Core boxes are labelled with the hole number, box sequence number, and the interval in metres. Almost all boxes are labelled with an aluminum tag. All rejects and pulps from the laboratory are also stored on site. Pulps are categorized by batch number and are stored inside sea containers. Rejects are stored inside plastic crates under temporary shelter.

QA/QC program results do not indicate any significant issues with the sampling and analytical programs. The quality of the analytical data is sufficiently reliable to support Mineral Resource estimation without limitations on Mineral Resource confidence categories.

3.Data Verification

Côté

The 2019 Côté drill hole database consisted of the 2018 Mineral Resource estimate data updated with files provided by IAMGOLD for the drilling performed since the 2018 Mineral Resource estimate. The drill hole information added to the data base since the 2018 Mineral Resource estimate consisted of 4,882 samples from 38 drill holes, totalling 4,854.8 metres of core.

The 2018 Côté drill hole database had previously been validated internally for the 2018 Mineral Resource estimate. In 2017, the Côté database was validated during the preparation of a Mineral Resource update.

IAMGOLD's internal validation for the 2019 Côté drill hole database included checks on collar position, down hole deviation survey, drill logging information, sampling procedures, and assay data.

The 2019 drill hole database were compared against static versions of the previously validated 2017 and 2018 versions. Assay certificates for the samples collected since the 2018 Mineral Resource estimate were compiled and compared to the 2019 data. No issues were identified.

As part of standard procedures, the 2019 database was verified using the validation tools available in Seequent's Leapfrog and Geovia Gems. Checks on minimum and maximum values for various data fields, the presence of negative or zero values, and checks for the presence of unusual symbols were performed. Visual inspection of borehole traces and comparison of collars and topographic surfaces were performed, as well as checks for gaps in the logging and interval overlaps.

A site visit to the Côté deposit was carried out on October 7 to 8, 2019. During the site visit, the work performed at Côté Gold Project was reviewed. The review included outcrop observations, collar position check with a hand-held GPS, review of core handling, logging, and sampling procedures. Core from several drill holes was reviewed, covering the main lithologies and mineralization styles. Drill logs and assay results from the selected drill holes were compared against the core.

All of the data required to conduct the data verification work was available and accessible and there are no limitations on this work.

- 54 -

The drill hole database complies with industry standards and is adequate for the purposes of Mineral Resource estimation.

Gosselin

The Gosselin deposit has been drilled by IAMGOLD since 2016. As the footprint of the mineralized zone increased, drilling proximal to Gosselin and adjacent deposits was used to complement the information collected during the Gosselin drilling campaigns. Historical drilling of the Gosselin deposit or nearby dates since 1987, with the bulk of the information collected after 2010. The Gosselin Mineral Resource estimation drill hole database has been maintained and updated by IAMGOLD personnel.

A site visit to the Gosselin deposit was carried out on July 19 to 21, 2021. During the site visit, the work performed at Gosselin was reviewed. The review included stops at various outcrops and at working drill rigs on land and lake. Collar positions were measured with a hand-held GPS. Core handling, logging, sampling, assay methodology, and QA/QC protocols were reviewed. Relevant intervals of core from various holes were examined, comparing the logged information to the core. The assay results were reviewed along with the core for the mineralized intercepts. Quartered core material was collected, from the half core witness material, as check samples to confirm the presence of mineralization in the Gosselin drilling. The selected mineralized intercepts had grades above the intended resource cut-off value and came from two recent drill holes that were also part of the drill core reviewed during the site visit. The mass of the quartered core check samples is half of that submitted for assaying original field samples and field duplicate samples, hence the assay results of the check samples were generally not expected to be fully comparable to the to the original samples. The samples preparation and assay method are similar to those used for the original samples.

The Gosselin drill hole database is maintained by IAMGOLD's exploration team in MS Access. Drill hole logs, assay certificates, deviation survey measurements, and density data are collected in data sheets, subjected to validation protocols, and then imported into the master MS Access database.

The supplied drill hole data was verified prior to commencing Mineral Resource estimation. The validation steps included checks of:

• sample length;

• maximum and minimum values;

• negative values;

• detection limit/zero values/unusual symbols;

• borehole deviations;

• interval gaps;

• interval overlaps;

• drill hole collar versus topography;

• comparison of assay certificate versus database values;

IAMGOLD provided assay certificates for database validation. Values from 202 assay certificates were compared to the Gosselin database assay table. A total of 37,797 samples were matched, representing approximatively 80% of the samples in the Gosselin database. No issues were identified. It is recommended that the unified Gosselin resource database, in addition to the currently available details, be updated with information identifying the assay laboratory file source of the final gold value. This will enhance the auditability of the database content and facilitate tracking of the relevant certificate in the case of re-assayed sample batches.

- 55 -

The data required to conduct the data verification work was accessible and available and there are no limitations on this work.

The Gosselin drill hole database complies with industry standards and is adequate for the purposes of Mineral Resource estimation.

Mineral Processing and Metallurgical Testing

Metallurgical laboratories involved with the test work programs have included: SGS facilities in Lakefield, Ontario, COREM (a consortium composed of several mining companies and the Government of Québec), in Québec City, Québec, and the University of British Columbia.

Metallurgical test work completed since 2009 has included: comminution (Bond low-impact (crusher), RWi and BWi, Ai, SMC, HPGR, piston press, and Atwal) tests, GRG tests, cyanide leaching (effect of head grade, effect of grind size, reagent usage, CIP modelling, cyanide destruction, solid-liquid separation and barren solution analysis) test work, development of recovery projections; and review of the potential for deleterious elements.

The comminution test work indicated that the material tested was very competent, and that the mineralization is well-suited to an HPGR circuit.

The mineralization is free-milling (non-refractory). A portion of the gold liberates during grinding and is amenable to gravity concentration and the response to gravity and leaching is relatively consistent across head grades. Therefore, the lower grade gold material is expected to exhibit the same level of metal extraction. Individual lithologies follow the general trends for grind size sensitivity and cyanide consumption, however, there is evidence of differences in free gold content. Silver content is consistently reported below 2 g/t Ag and the test work does not report on silver recovery.

Overall gold recovery is estimated at 91.8% for the processing at an initial rate of 35,500 tpd using the proposed flowsheet, with a later expansion to 37,200 tpd. Cyanide and lime consumption are quite low in comparison to what is typically observed in industry, however, this reflects the lack of cyanicides and other cyanide consuming elements. Lime consumption is also positively impacted by the basic nature of the ore.

Metal dissolution during cyanide leaching was found to be low, and there are no obvious concerns with deleterious elements.

Overall, metallurgical test results indicate that all the variability samples were readily amenable to gravity concentration and cyanide leach. Samples selected for metallurgical testing were representative of the various types and styles of mineralization within the different zones. Samples were selected from a range of locations within the deposit zones. Sufficient samples were taken so that tests were performed using adequate sample weights.

For the Gosselin deposit a preliminary test work program was complete in the summer of 2020. The comminution parameters and gold recovery are similar to those of the Côté Gold Project ore. Cyanide and lime consumption were slightly higher for Gosselin material, due to the higher copper and sulphur content.

A more detailed test work program needs to be undertaken for the Gosselin deposit. The program should include gravity recovery and metal dissolution characterization.

Côté

The Mineral Resources estimates for Côté can be located in the "Mineral Resources as of December 31, 2023" table in "Mineral Resources Estimates" above.

In 2019, an updated Côté Mineral Resource estimate was prepared, which included the incorporation of ‎additional drilling and updated mineralization wireframes, recognized local grade trends, eliminated the ‎fault domain, and used a new classification approach. IAMGOLD is treating the December 19, 2019, ‎estimate as the current Mineral Resource estimate for the Côté deposit‎.

IAMGOLD is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing, political, or other relevant factors that could materially affect the Mineral Resource estimate.

At the time of data handover, IAMGOLD was in the process of rebuilding the assay database for the Côté deposit. IAMGOLD provided the 2018 Mineral Resource estimate database and data for the 2019 drilling. The previously validated 2018 Côté database was merged with more recent drilling data in order to create the database for the December 2019 Mineral Resource estimate update.

The 2019 Côté database, with a data cut-off at the end of September 2019, contained 750 drill holes, for a total of 311,034 metres drilled. The assay table contained 300,768 samples, with a total length of 294,399 metres of sampled core. Down hole deviation survey, lithology, alteration, ICP analysis results, mineralization, and structural information were also present in the database.

IAMGOLD geologists prepared updated lithology, mineralization, and overburden domains incorporating the 2019 drilling information available. Wireframes were provided as separate dxf files and as a Seequent Leapfrog project. The provided Côté wireframes were reviewed and adopted. Subsequently, it was decided to consider the fault domain as a plane and to distribute the volume of the provided fault domain in the neighbouring domains. The plane of the fault, as redefined, is a break in grade along the fault intercept. This plane was then used as a boundary for lithology and interpolation domains.

The mineralization, lithology, and fault plane allowed the separation of North and South, constrained (higher-grade, more continuous) and unconstrained (lower grade, low continuity) domains, with a further subdivision based on lithology. Additional surfaces and solids were created in Leapfrog and GEMS to allow finer control for grade interpolation purposes inside the extended breccia domains. Grade trends were identified, investigated, and modelled.

Assays were back-flagged with mineralization and lithology information for descriptive statistics. It was noted that high-grade gold samples were observed in almost all of the subdomains. To reduce the influence of the erratic high-grade values, a capping analysis was performed and determined capping levels for the various domains using histograms, probability plots, decile analysis, and disintegration analysis. Following the application of capping to raw data, assay intervals were composited to six metre equal length intervals within each domain, starting at the domain wireframe piercing points. Composites shorter than two metres (one third of the nominal composite length) generated at the end of some intercepts were discarded. Similarly, composites with less than two metres of sampled core, predominantly representing overburden and diabase dike intercepts, were discarded prior to estimation.

The selected indicator gold grade shells:

• Recognized the natural mineralization break at the main fault.

- 58 -

• Confirmed the modelled Extended Breccia volume: almost all volume in the South domain and a large proportion of the North domain is filled by the 0.3 g/t Au indicator shell.

• Highlighted the main grade trends for the North area: north-northeast (NNE) and east-west (EW), generally parallel to the fault (0.4 g/t Au shell).

• Highlighted grade trends for the South area: with variable dip and gently curved, aligned east-west (0.4 g/t Au shell).

• Delineated the core of higher-grade mineralization within the grade trends by the 0.7 g/t Au shell.

The local grade trends and volumes highlighted by these three grade shells were used as a guide to define interpolation subdomains inside the Extended Breccia wireframes. During the trend analysis process, it was noticed that the thinner low angle dikes (mafic, lamprophyre) appear in discrete bands, introducing local dilution. It is recommended that the behaviour of single dikes and groups of dikes be investigated and potentially modelled in future updates as they trend differently than the mineralization.

The compartmentalization and multiple grade trends in both the North and South areas, in conjunction with vertical and horizontal higher-grade components, as highlighted by the grade shells, makes variographic analysis challenging and open to interpretation, with any global results that do not consider the local structural subdomains being less reliable.

The approximative volumes were modelled based on individual grade trends to increase the probability of obtaining better behaved experimental variograms. Two partly overlapping wireframes were modelled for the North area, capturing the better-defined NNE trend and EW trend. These wireframes were later used to separate the 1101 and 1201 grade interpolation domains. In the South domain, one wireframe was modelled in the central part of the Extended Breccia to capture the S-EW trend. The South domain trend wireframe includes a mix from three interpolation subdomains.

It was noted that for the investigated subdomains, the experimental variogram ranges observed were 90 metres to 150 metres for major and semi-major directions, while minor ranges were generally within 50 metres. The relative nugget effect was modelled as 20%. Modelled variograms reached 80% to 90% of the sill at a range of approximately 50 metres for the major and semi-major directions.

A block model was generated in GEOVIA GEMS 6.8.1 software. The block model has a block size of 10 metres wide by 10 metres deep by 12 metres high. The block model is rotated 30° (GEMS rotation convention). The block size is appropriate for the intended open pit operation planning and adequate for the drill hole spacing at Côté.

Blocks in the model were initially flagged with lithology and mineralization, with the majority rule used to determine the flagging of a block with respect to modelled wireframes. Blocks outside the modelled lithology wireframes were assumed to be tonalite and flagged accordingly in order to facilitate processing of the block model data in the pit optimization algorithm.

For estimation domains, the in-situ blocks (below the overburden) were flagged using the mineralized Extended Breccia North and South wireframes (with higher precedence) and the low-grade North and South solids. Barren dike wireframes were not used for the interpolation domains flagging. Four main volumes were separated, the 100 (N) and 200 (S) for low-grade and 1000 (N) and 2000 (S) for constrained mineralization.

This flagging was assigned to the composites. Blocks in the low-grade domain were then flagged with 101 and 202, respectively. The 1000 domain was separated into three subdomains, one reflecting the NNE grade trend (1101), one the EW trend (1201), and the remaining volume with mixed influence (1001). The 2000 domain was separated into six subdomain reflecting the local grade trends: isotropic for 3202 and 3502, dipping north for 3102 and 3402, dipping vertically for 3302, and dipping south for 3602.

- 59 -

The lithology domains were based on the diorite, diorite breccia, and hydrothermal breccia wireframes. Blocks were then reflagged as dike where this wireframe represented the majority of a block. The overburden wireframe had the highest precedence for lithology flagging. The lithology flagging, in combination with the area (North or South), were used as the basis to assign density.

After interpolation and classification, grade and classification were transferred to a final set of attributes. At this stage, blocks from assumed barren lithological domains (dike and overburden) were sterilized. This final set of parameters was used for pit optimization and resource reporting.

The Côté grade block model was interpolated in one pass. The gold grades were estimated using six metre composites and the inverse distance cubed (ID3) interpolation method (anisotropic). This method helps preserve local grades when using mineralized wireframes with occasional internal dilution and with lower grade intercepts. Additionally, the experimental variograms reach high levels of variance within relatively short distances. Alternative interpolation methods were used for block validation purposes. The Extended Breccia domains shared the composites for all the subdomains. Hard boundaries were enforced between low and high-grade domains and between the North and South areas.

A total of 2,031 bulk density measurements from core samples were available for review. Preliminary outlier identification and removal was performed by IAMGOLD, eliminating readings of less than 2.4 g/cm3 and higher than 3 g/cm3. The density data was separated by lithology, mineralization, and position with respect to the fault. The diorite average values in different subdomains exhibited contrasting values, hence the average value for each individual subdomain was used for the block model.

Drill hole spacing tests were performed for the Côté deposit using the 2018 data in order to assess the classification criteria for Measured Mineral Resources. The grade of blocks in the tightly drilled South domain were estimated repeatedly, each time reducing the number of holes available for estimation. The results obtained using drill hole spacings from actual to 90 metres were upscaled to quarterly and yearly production volumes. The average percent difference in grades for blocks above cut-off grade between volume units was plotted in conjunction with the minimum and maximum differences. While the results of this test agree with the drill spacings of 44 metres for Measured and 66 metres for Indicated categories, this test effectively tests for average grade variations in a fixed volume and does not account for volume variations that would occur if the mineralized volume were to be interpreted separately for each of the drill hole spacing scenarios. Changing the interpretation of the mineralized volume would increase the differences between spacing scenarios. This would most likely result in increasing the spread of the differences and suggests that a tighter drill hole spacing for the Measured Mineral Resource classification might be required in the future.

Definitions for resource categories used in the Côté Gold Report are consistent with CIM (2014) definitions as incorporated by reference into NI 43-101. In the CIM classification, a Mineral Resource is defined as "a concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction". Mineral Resources are classified into Measured, Indicated, and Inferred categories. A Mineral Reserve is defined as the "economically mineable part of a Measured and/or Indicated Mineral Resource" demonstrated by studies at PFS or Feasibility level as appropriate. Mineral Reserves are classified into Proven and Probable categories.

The classification uses a combination of interpreted geological continuity, expressed by the Extended Breccia wireframe, and drill hole spacing, expressed as average distance between drill holes and distance from the closest hole.

Interpolated blocks within the Extended Breccia wireframes were considered as candidates for classification in the Inferred category and higher, while blocks outside these wireframes were only considered for the Inferred category.

Extended Breccia blocks in areas with up to 44 metres drill hole spacing and within 25 metres from the closest drill hole were classified as Measured. Extended Breccia blocks in areas with drill hole spacing up to 66 metres and within 40 metres from the closest drill hole were classified as Indicated. The remaining interpolated blocks, if located in areas with drill hole spacing up to 110 metres and within 75 metres from the closest drill hole, were classified as Inferred. Average drill hole spacing for the Measured and Indicated categories was based on the average distance of a hole to the nearest five holes. For the Inferred category, the average to the nearest three holes was used, to eliminate artifacts generated by the numerical approach observed at the edges of the drilled area and at depth. A minimal manual cleanup of the scattered blocks from all classes was performed.

- 60 -

It is recommended additional block classification smoothing work be carried out in the future in order to eliminate the presence of occasional small clusters of blocks of different classes generated by the essentially numerical approach used for this estimate. It is noted that this would primarily result in upgrading a small number of Inferred blocks to Indicated and would have a negligible impact.

Metal prices used for Mineral Reserves are based on consensus, long-term forecasts from banks, financial institutions, and other sources. For Mineral Resources, metal prices used are slightly higher than those for Mineral Reserves. The Mineral Resources were reported at a cut-off grade of 0.3 g/t Au and constrained by an optimized resource shell. Only the blocks inside the resource shell were reported. This is similar to the cut-off value and approach used for the 2018 Mineral Resource estimate. In compliance with the CIM (2014) requirement that Mineral Resources demonstrate "reasonable prospects for eventual economic extraction". Preliminary Lerchs-Grossmann pit shells were prepared to constrain the Mineral Resources. The cost and parameters assumed for the Côté deposit are the same as those used in 2018.

Capping levels were established using statistical methods. In order to understand the overall influence of capping on the Côté Mineral Resource estimate, the uncapped Mineral Resources were estimated and reported. The Measured and Indicated metal lost due to capping is 19% for the current Mineral Resource estimate. It is noted that for the 2018 Mineral Resource estimate, the metal reduction due to capping was similar, while metal loss in the 2012 Mineral Resource estimate was 22% in the NE domain and 14% in the SW domain and metal loss in the 2016 Mineral Resource update was 15% in the NE and 16% in the SW domain.

Several changes have been implemented in the current Mineral Resource estimate compared to the 2018 Mineral Resource estimate:

• Incorporation of additional drilling.

• Update of the mineralization wireframes with a minor increase in volume.

• Minor variations of the density values as a result of additional measurements.

• Elimination of the fault domain.

• Subdomaining of the Extended Breccia wireframes according to observed local trends.

• Resource classification independent of alteration wireframes.

It is noted that the additional drilling, mineralization wireframe adjustments, density measurements, and grade estimation approach introduced minor changes overall. The largest changes included a firmer application of the classification criteria, resulting in a reduction of the Measured Mineral Resources, and detaching classification from the modelled alteration wireframes, resulting in the addition of significant Inferred Mineral Resources. Previously the blocks outside the modelled mineralization wireframes were considered for the Inferred classification only if they were situated inside alteration wireframes that were considered favourable for mineralization.

Gosselin

The Mineral Resources estimates for Gosselin can be located in the "Mineral Resources as of December 31, 2023" table in "Mineral Resources Estimates" above.

In 2021, an estimate of the Gosselin Mineral Resources was prepared based on an open pit mining scenario. Indicated Resources total 124.5 Mt at an average grade of 0.84 g/t Au, containing 3.35 Moz Au. An additional 72.9 Mt at an average grade of 0.73 g/t Au, containing 1.71 Moz Au are estimated in the Inferred Mineral Resource category. The Mineral Resources are estimated at a 0.3 g/t Au cut-off grade, based on a price of $1,500/oz Au, and have an effective date of October 4, 2021.

IAMGOLD is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing, political, or other relevant factors that could materially affect the Mineral Resource estimate.

A drill hole database for the Gosselin deposit was prepared and provided by IAMGOLD. The Gosselin database contains records of core drilling completed until the end of July 2021. Collar position, down hole deviation survey, gold assay, lithology, density, structural, alteration, mineralization, ICP, magnetic susceptibility, RQD, and recovery information are stored in separate tables. The Gosselin database was provided by IAMGOLD as part of a Seequent Leapfrog 2021.1 project and as separate csv files. The Gosselin Leapfrog project also contained interpreted geology wireframes and topography. The Gosselin database contains information from 163 drill holes with a total length of 54,775.4 metres.

IAMGOLD geologists prepared geological model wireframes in Leapfrog, using an implicit modelling approach with occasional manual control features. The wireframes provided were reviewed and found to be appropriate for Mineral Resource estimation purposes. The Gosselin mineralization wireframes were defined in Leapfrog with a nominal cut-off grade of 0.3 g/t Au and modelled using implicit modelling aided by modelled trend surfaces and manual control features. The Gosselin mineralization wireframes included lower grade intercepts to preserve the continuity of the solids and prevent unnecessary fragmentation, following the geometry of the lithological units where appropriate. The trend surfaces used to aid the mineralization wireframes were based on the grade trends demonstrated by gold grade shells at various cut-off values. Additional wireframes were modelled based on the grade shells to generate estimation subdomains inside the mineralization wireframe. A 200-metre wide buffer of waste material and occasional isolated mineralization intercept was defined and used as an unconstrained domain.

Data from 159 holes was used for the Gosselin Mineral Resource estimate, for a total drill length of 50,106 metres and 45,124 samples. Capping of high-grade assays prior to compositing is a practice aimed at limiting the influence of erratic high-grade assays, which otherwise have the potential to overpower surrounding lower grade samples. In the absence of production data that would allow the determination of appropriate capping levels, a number of statistical methods are used. Statistical methods were applied to establish the capping levels for Gosselin. Lithological domains were used as capping domains inside the modelled mineralization wireframe, while in the buffer wireframe all the various mineralized lithologies received the same capping value. A combination of histograms, decile analysis, probability plots, disintegration, and visual inspection of the spatial location of higher-grade assays was used to determine the capping levels for each capping domain. High-grade assays were capped prior to compositing. Resource samples were composited prior to grade estimation. A fixed interval compositing length of six metres was selected. Compositing was completed from collar to toe within mineralization wireframes, starting at the wireframe pierce-point and continuing to the point at which the hole exited the lens. Composites shorter than half the compositing length were added to the previous interval. Composites of capped assays were used for Mineral Resource estimation.

The relationship between sample gold grade and lithology was investigated for the Gosselin deposit. Assay data was flagged according to the lithological model. Initially, an apparent relationship between lithological domains and grade was observed. Subsequently, grade shells at various cut-off values indicated that lenses of better grade continuity may be separated within the modelled mineralization domain. In order to isolate more homogeneous grade domains, a set of estimation subdomains were modelled for the mineralization wireframe, capturing the local grade trends.

The available Gosselin alteration wireframe, while generally simulating the presence of mineralization and the modelled mineralization wireframe, did not appear to be consistently related to the mineralization. As a result, the focus was on lithology and grade information for the Gosselin Mineral Resource estimate. It is recommended to continue the collection of alteration data and regular updates of the modelled alteration wireframes for the Gosselin deposit. Grade shells with cut-offs of 0.4 g/t Au, 0.6 g/t Au, 0.8 g/t Au, and 1.0 g/t Au were used as a guide for subdomain estimation modelling.

The Gosselin estimation subdomains capture the local grade trends and respect breaks in the mineralization or changes in orientation. The intersection between the mineralization wireframe and estimation subdomains was used to parse the data for variographic analysis in Supervisor 8.14 and later for guiding the block grade estimation in Leapfrog.

In general, the capped composites produced variograms with erratic behaviour. In order to reduce the variance, the data for variographic analysis was capped at a lower value of 4.0 g/t Au for all the estimation domains. Overall, approximately 80% of the sill for the major and semi-major ranges was reached within 60 metres to 80 metres. 70 metres was considered as nominal drill hole spacing for classification.

A block model was generated in Seequent's Leapfrog 2021 software to support the Gosselin Mineral Resource estimate. The block model for the Gosselin deposit has a block size of 10 metres wide by 10 metres deep by 12 metres high. The block model is rotated, aligned parallel to the average strike of the Gosselin deposit. The block size is appropriate for the intended open pit operation planning and adequate for the drill hole spacing at Gosselin. The Gosselin gold grade block model was interpolated in two passes inside the mineralized wireframe, and in one pass in the buffer domain. The gold grades were estimated using six metre composites with the ID3 interpolation method. The ID3 method was favoured in order to preserve local grades in the context of using mineralized wireframes with occasional internal dilution and with lower grade intercepts. All the subdomains inside the mineralized wireframes have soft boundaries, and hard boundaries between the mineralized wireframe and the buffer domain.

The Gosselin drill hole database contained 1,249 density measurements from all the lithological unis. The data were separated by lithology and analyzed. Occasional outliers were removed prior to calculating the average bulk density value for each of the lithology domains. The average domain values were used for the Gosselin deposit. The average values were assigned to blocks in the block model flagged with lithology domains.

Definitions for resource categories used in the Côté Gold Report are consistent with CIM (2014) as incorporated by reference into NI 43-101. In the CIM classification, a Mineral Resource is defined as "a concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction". Mineral Resources are classified into Measured, Indicated, and Inferred categories. A Mineral Reserve is defined as the "economically mineable part of a Measured and/or Indicated Mineral Resource" demonstrated by studies at PFS or Feasibility level as appropriate. Mineral Reserves are classified into Proven and Probable categories.

Indicated Resources are classified where estimated blocks are situated inside the mineralized wireframe and inside the modelled estimation domains, within up to a 60 metres to 70 metres drill hole spacing, interpolated with a minimum of two drill holes. Indicated blocks are expected to be within a maximum distance of 45 metres from the closest drill hole.

Inferred Resources are classified as blocks estimated with a minimum of one hole. Inferred blocks occur inside the constrained volume of the mineralization wireframe and outside the modelled estimation domains, within maximum distance to the closest composite of 100 metres. Interpolated blocks in the buffer volume, within 75 metres from the closest drill hole were also classified in the Inferred category.

Visual and statistical methods were used to validate the block model attributes, domain flagging, and interpolated block grades at Gosselin. The checks performed included:

- 63 -

• comparison of mineralized lenses with the flagged blocks;

• spot checks for search ellipse alignment along mineralized lenses;

• spot checks for composite and estimation domain flagging;

• visual checks for interpolated grade artefacts (banding, smearing of high grades, and high grade plumes);

• visual comparison of composite and block grade in section and plan view;

• comparison of composite and block grades in swath plots; and

• comparison of interpolated block grades obtained by alternate interpolation methods;

Metal prices used for Mineral Reserves are based on consensus, long-term forecasts from banks, financial institutions, and other sources. For Mineral Resources, metal prices used are slightly higher than those for Mineral Reserves.

In compliance with the CIM (2014) requirement that Mineral Resources demonstrate "reasonable prospects for eventual economic extraction", Lerchs-Grossmann pit shells was prepared to constrain the Mineral Resources. The Mineral Resources were reported at a cut-off grade of 0.3 g/t Au and constrained by the optimized Mineral Resource shell. Only the blocks inside the Mineral Resource shell were reported.

The Gosselin deposit is located to the east of, and adjacent to, the Côté deposit. The Mineral Resource shells developed for the two deposits overlap slightly, this will benefit both deposits. It is noted that the Mineral Resource blocks reported for the Côté deposit (0.3 g/t Au and higher) were excluded from the Gosselin Mineral Resource estimate.

The Gosselin model blocks attributable to Côté total 0.13 Mt at an average grade of 0.54 g/t Au, and contained 2,260 oz Au, all in the Inferred category. These Mineral Resources were not reported in the Gosselin Mineral Resource estimate.

At the end of 2023, an updated estimate of the Gosselin Mineral Resources was prepared based on additional drilling, updated interpretation and financial parameters.

Between October 4, 2021 and October 6, 2023, 58 drill holes with a total length of 36,271.57 metres were added to the Gosselin database, for a total resource database comprising 221 drill holes for a total length of 91,046.97 metres. The drill hole database was prepared and provided by IAMGOLD. IAMGOLD geologists prepared the updated geological model in Leapfrog, and the model was found to be appropriate for Mineral Resource estimation purposes.

Similar to the 2021 mineral resource estimation, a nominal cut-off grade of 0.3 g/t Au was used to define the deposit, aided by modelled trend surfaces and manual control features. The mineralization wireframes were defined based on the grade trends, generated estimation subdomains inside the mineralization wireframes, and created an 800-metre-wide buffer of waste material.

Capping of high-grade assays prior to compositing limited the influence of erratic high-grade assays, which otherwise would have the potential to overpower surrounding lower grade samples. For the determination of appropriate capping levels, statistical methods were applied to establish the capping levels for Gosselin. Lithological domains were used as capping domains inside the modelled mineralization wireframe, while in the buffer wireframes all the various mineralized lithologies received the same capping value. High grade assays were capped prior to compositing, and samples were composited prior to grade estimation.

- 64 -

The continuity of gold grades in the Gosselin deposit was assessed by creating a series of isotropic gold grade shells at various values using Leapfrog, without constraint to the mineralized envelope. Several sub-vertical trends were discerned, typically oriented in a southwest to northeast direction (NE Trend) and a second trend orientated at approximately 300 degrees (300° Trend). The orientation of these trends played an important role during the setup of search ellipses, experimental variography, and variable orientation gold grade interpolation.

A block model was generated in Seequent's Leapfrog 2021 software to support the updated Gosselin Mineral Resource estimate. The block model for the Gosselin deposit has a block size of 10 metres wide by 10 metres deep by 12 metres high. The Gosselin gold grade block model was interpolated in two passes inside the mineralized wireframe, and in one pass in the buffer domain. The gold grades were estimated using six metre composites with the ID3 interpolation method. The ID3 method was favoured in order to preserve local grades in the context of using mineralized wireframes with occasional internal dilution and with lower grade intercepts.

A classification methodology was implemented at Gosselin, generating classification solids supported by drill hole spacing. Indicated Resources are classified where estimated blocks are situated inside the 0.3 g/t Au mineralized wireframe and inside the modelled estimation domains, within up to 70 metres drill hole spacing, and interpolated with a minimum of three drill holes. Indicated blocks are expected to be within a maximum distance of 50 metres from the closest drill hole. Inferred Resources are classified where estimated blocks are situated inside the 0.3 g/t Au mineralized wireframe and inside the modelled estimation domains, within up to 140 metres drill hole spacing, interpolated with a minimum of three drill holes. Some lower grade material and drill holes beyond the drill spacing criteria for Inferred material were included to preserve continuity.

A Lerchs-Grossmann pit shells were prepared to constrain the Mineral Resources. The Mineral Resources were reported at a cut-off grade of 0.3 g/t Au and constrained by the optimized Mineral Resource shell. Only the blocks inside the Mineral Resource shell ‎were reported.‎

1.The Côté Property Royalty covers the northern portion of the Côté reserve pit for a total coverage of less than 10% of the Côté reserve & resource estimate.

2.Mineral Reserve estimates are prepared in accordance with NI 43-101.

3.Côté Gold Mineral Reserves have been estimated as of December 31, 2023 using a $1400/oz gold price.

4.Mineral Reserves are estimated assuming open pit mining methods and are reported on a 100% Project basis.

5.Bulk density values range from 2.69 t/m3 to 2.85 t/m3.

The cut-off applied to the reserves is 0.35 g/t Au.

7.All figures have been rounded to reflect the relative accuracy of the estimates.

8.The above assumptions are based on the Côté Technical Report and may not reflect or address all of the assumptions in the ‎revised Mineral Reserves estimates as of December 31, 2023.

All currently defined Mineral Reserves at the Côté Gold Project are located in the Côté deposit. Accordingly, unless otherwise indicated, the reminder of the discussion below regarding the Côté Gold Project focuses exclusively on the Côté deposit (for which the Côté Property Royalty has a total coverage of less than 10%) and not the Gosselin deposit.

Mineral Reserves were classified in accordance with the CIM (2014) definitions. Only Mineral Resources that were classified as Measured and Indicated were given economic attributes in the mine design and when demonstrating economic viability. Mineral Reserves for the Côté deposit incorporate mining dilution and mining recovery estimations for the open pit mining method.

The Mineral Reserves estimates for the Côté Gold Project can be found in the "Mineral Reserves as of December 31, 2023" table in "Mineral Reserves Estimates" above.

The Mineral Reserve estimate for the Côté deposit is based on the resource block model estimated by IAMGOLD (May 2023).

Mineral Reserves are an estimate of the tonnage and grade of ore that can be economically mined and processed. To be considered Mineral Reserves the estimated material must pay for all costs incurred during mining. The mine plan is based on the detailed mine design derived from the optimal pit shell produced by applying the Lerchs-Grossmann (LG) algorithm. The resource model, containing gold grades, block percentages, material density, slope sectors, rock types, and NSR, was imported into the optimization software. The optimization run was carried out using only Measured and Indicated Mineral Resources to define the optimal mining limits. Inferred Mineral Resource blocks were treated as waste.‎

The optimization run included 55 pit shells defined according to different revenue factors, where a revenue factor of 1 is the base case. To select the optimal pit shell that defines the ultimate pit limit, a pit-by-pit analysis was conducted to evaluate the contribution of each incremental shell to NPV, assuming a processing plant capacity of 36,000 tpd and a discount rate of 6%. Following this analysis, the selected pit shell is usually smaller than the base case pit shell. This represents a NPV improvement of $17.9 million over the base case pit shell.

The resource model is diluted by regularizing to a standard block size of 10 metres wide by 10 metres deep by 12 metres high. Individual blocks captured within the final pit design were tagged as either ore or waste by cut-off grade, accounting for increasing mining costs with depth and varying royalties by zone. Ore losses during mining are accounted for by simulating the mixing of material from adjacent blocks. The procedure to determine ore losses during mining results in a reduction of gold grade but does not reduce tonnage.

Ore losses were estimated using the following steps:

- 66 -

• The grade of a given block will be blended using 5% of the tonnage from each of the four adjacent blocks.

• If an adjacent block is classified as an Inferred Mineral Resource, its grade is considered to be zero. If the adjacent block is Measured or Indicated, but below cut-off, dilution is taken at the grade of the adjacent block.

The estimated average ore losses using this procedure is 0.7%.

The Mineral Reserve estimate includes the tonnage and grade of ore that can be economically mined and processed. To be considered Mineral Reserves the mineralized material must pay for all costs, including mining, processing, selling, and rehandling, in addition to royalties.

Since the mining cost increases with depth and the royalty percentage varies by zone, individual blocks captured within the final pit design were tagged as either ore or waste. Using the partial block percentages within the final pit design, the ore tonnage and average grade were estimated.

The cut-off grade applied to the reserves is 0.35 g/t Au. The effective date of the Mineral Reserves estimate is December 31, 2023.

There is a reasonable expectation that all permitting required to support the Mineral Reserve-based LOM plan will be obtained.

There are no mining, metallurgical, infrastructure, permitting, or other relevant factors that could materially affect the Mineral Reserve estimate.

Note that:

• Pit optimization parameters, financial assumptions, pit-shell selection, and mining dilution and recovery factors remain unchanged from 2018.

• The current tailings management facility ("TMF") permit covers approximately 87% of the Mineral Reserves.

Mining Operations

Pit optimization parameters, financial assumptions, pit-shell selection, and mining dilution and recovery factors remain unchanged from 2018. The current Mineral Reserves are based on an updated mine design which optimizes pit phasing, ramp location, and waste stripping, resulting in negligible changes to Mineral Reserves compared to the previous estimate, and small reductions in waste.

The mine plan was updated to a feasibility level pit slope design by carrying out geomechanical logging, compilation of previous geotechnical data, geotechnical modelling, kinematic analysis, and confirmation of overall slope stability by limit equilibrium and finite element analysis. Initial pit slope design criteria were based primarily on all the compiled, reconciled, and updated geomechanical data, with reference to the prefeasibility study (PFS) pit shell geometry defined by Amec Foster Wheeler (2017). Following pit optimization, the pit geometry was compared for changes in the slope orientation that may be impacted by different kinematic influences and reviewed using limit equilibrium modelling of the potential modes of failure to determine adequacy of the bench and inter-ramp design, with recommendations for adjustments which were incorporated into the final pit design.

The pit shells that define the ultimate pit limit, as well as the internal phases, were derived using the Lerchs- Grossmann (LG) pit optimization algorithm. This process considers the information stored in the geological block model, the pit slope angles by geotechnical sector, commodity prices, cost inputs, and royalties by zone.

- 67 -

The resource model, containing gold grades, block percentages, material density, slope sectors, rock types, and net smelter return (NSR), was imported into the optimization software. The optimization run was carried out using only Measured and Indicated Mineral Resources to define the optimal mining limits.

The optimization run included 55 pit shells defined according to different revenue factors, where a revenue factor of 1 is the base case. To select the optimal pit shell that defines the ultimate pit limit, a pit-by-pit analysis was conducted to evaluate the contribution of each incremental shell to NPV, assuming a processing plant capacity of 36,000 tpd and a discount rate of 6%. In 2022, pit optimizations run with current inputs confirmed the previous pit shell selection.

The mine plan is designed as a truck-shovel operation assuming 212 tonne autonomous trucks and 34 cubic metre shovels. The pit design includes five phases to balance stripping requirements while satisfying concentrator requirements.

The design parameters include a ramp width of 36 metres, maximum road grades of 10%, bench height of 12 metres, berm height interval of 24 metres, geotechnical catch bench of 20 metres if height is greater than 150 metres, a minimum mining width of 40 metres, and variable slope angles and berm widths by sector.

The smoothed final pit design contains approximately 235 Mt of ore at 0.95 g/t Au and 575 Mt of waste for a resulting stripping ratio of 2.4:1. The total LOM mill feed is 233 Mt at 0.96 g/t Au, constrained by TMF capacity, and 2.3 Mt of low-grade ore material remaining in stockpiles at the end of mine life. These tonnages and grades were derived by following an elevated cut-off strategy in the production schedule.

The mine rock area (MRA), overburden stockpile, and ore stockpiles have been designed to ensure physical and chemical stability during and after mining activities. To achieve this, the storage facilities were designed to account for benching, drainage, geotechnical stability, and concurrent reclamation.

Pre-production commenced with contractor works in Q1 2021 consisting of overburden removal, supply of material for construction, and initial bench establishment. Contractor mining continued until Q2 2023. Owner mining commenced in Q1 2023 with a fleet of autonomous haulage trucks. Mechanical completion ‎and first gold are expected in Q1 2024 with commercial production expected in the third quarter of 2024.‎

The Côté deposit is planned to be mined in five phases included within the ultimate pit limit. The scheduling constraints establish the maximum mining capacity at 70 Mtpa and the maximum number of benches mined per year at eight in each phase. Additional constraints were used to guide the schedule and to obtain the desired results. Examples of these additional constraints include feeding lower grade material during the first months of the plant ramp up schedule, the maximum stockpile capacity, and reducing the mining capacity in later years to balance the number of trucks required per period.

The schedule produced an 18 year LOM with stockpile reclaim accounting for the final four years. The amount of re-handled mill feed is 78 Mt, which requires a maximum stockpile capacity of 55 Mt, in Year 13. The average grade is 0.96 g/t Au.

The mine is scheduled to operate 24 hours per day, seven days per week (24/7 schedule), using four rotating crews working 12 hour shifts.

Mining operations will use an autonomous truck and drill fleet, supported by a conventional manned loading fleet and a fleet of manned support equipment. The truck fleet will be diesel-powered with the capacity to mine approximately 60.0 Mtpa operating on 12 metres benches. The loading fleet will include two electricpowered hydraulic shovels, supported by three large diesel-powered front-end loaders (FELs). Primary mobile equipment will consist of:

• Loading - CAT 6060 electric/hydraulic (6060E) shovel and CAT 994K high lift FELs.

- 68 -

• Hauling - CAT 793F mechanical drive truck operated in autonomous mode.

Multiple contractors will support the mine. A maintenance and repair contract (MARC) was put in place in Q1 2023 for pre-production and the first three years of operation. Blasting will be conducted by a contract down hole service during the LOM. A tire maintenance agreement was put in place in Q3 2022 to repair and change tires at the mine site.

Processing and Recovery Operations

The process circuits will include primary crushing, secondary crushing, HPGR, ball milling, vertical milling, gravity concentration and cyanide leaching, followed by gold recovery by CIP, stripping and EW. Tailings handling will incorporate cyanide destruction and tailings thickening. Plant throughput will initially be 35,500 tpd at 92.6% utilization and it is expected that a ramp up period of 20 months will be required to reach the design throughput, however, it is expected that 90% of the design throughput will be achieved after 10 months. Preliminary test work has indicated that the Gosselin deposit is similar to the Côté deposit, however, additional test work is required to validate and confirm this.

The process plant design is conventional and uses conventional equipment. The process plant will consist of:

• primary (gyratory) crushing;

• secondary cone crushing and coarse ore screening;

• a coarse ore stockpile;

• tertiary HPGR crushing;

• fine ore screening and storage;

• two milling stages (ball mill followed by vertical stirred mills);

• gravity concentration and intensive leaching;

• pre-leach thickening;

• whole ore cyanide leaching;

• CIP recovery of precious metals from solution;

• cyanide destruction;

• tailings thickening;

• elution of precious metals from carbon;

• recovery of precious metals by ew; and

• smelting to doré.

The processing plant will have facilities for carbon regeneration, tailings thickening, and cyanide ‎destruction. The ramp-up period will be highly influenced by design considerations, especially pertaining ‎to the grinding circuit. The processing plant is expected to take 20 months to reach the initial design ‎throughput of 35,500 tpd. However, it is expected that throughputs of 90% of the design throughput will ‎be achieved after 10 months‎.

- 69 -

Water from the mine water pond will be the primary source of mill water, providing the majority of the processing plant requirements, whereas the plant site pond and other collection areas will be secondary sources of process water. Fresh water required for reagent mixing at the processing plant will be pumped from Mesomikenda Lake.

The primary reagents required will include flocculant, sodium hydroxide, cyanide, copper sulphate, liquid sulphur dioxide, anti-scalant, lime, hydrochloric acid, and oxygen. A dedicated, self-contained air service system will be provided.

The mill will require approximately 54 MW of power to operate at full capacity.

Infrastructure, Permitting and Compliance Activities

1.Infrastructure, Permitting and Compliance Activities

a.Infrastructure

Project infrastructure will include:

• open pit;

• MRA and stockpile facilities;

• TMF;

• permanent camp and a temporary construction camp;

• emulsion plant;

• process facilities;

• workshop, offices, facilities, and other services;

• watercourse realignment dams and channels;

• new lake created to compensate for the loss of Côté Lake habitat;

• storm/mine water, polishing, and tailings reclaim ponds;

• collection, surplus water discharge, and dispersion systems;

• two-lane gravel access road;

• upgraded existing transmission line from Timmins to Shining Tree Junction and a new 44 kilometre long 115 kV electrical power transmission line from Shining Tree Junction to the Côté Gold Project site; and

• electrical distribution network.

Access to the Côté Gold Project prior to construction was via a network of logging roads and local bush ‎roads accessed from Highway 144 and from the Sultan Industrial Road, which runs east-west along and ‎below the southern portion of the Côté Gold Project area. The selected route to the processing plant is ‎the existing Chester Logging Road which has already been upgraded from the Sultan Industrial Road, ‎‎4.62 kilometres, at the intersection with an existing road to the open pit area. The upgraded road is nine ‎metres wide and serves as the main access to the mine site. From the upgraded road to approximately ‎the southeast corner of the TMF, Chester Logging Road was upgraded to a 10-metre design width. At ‎the corner of the planned TMF site, the existing road continues into the footprint of the TMF, and 4.28 ‎kilometres of new road was constructed to extend the access to the construction/permanent camp ‎entrance. This section of road was constructed as part of the early works and is used as the primary ‎construction access to the processing plant site and the camp area. A mine site bypass route will use the ‎existing Yeo Road, from the Sultan Industrial Road to a point opposite the northwest corner of the TMF, ‎without upgrade. From there a new connector road of 3.94 kilometres has been constructed to tie into an ‎existing road which runs parallel to the North Dam of the TMF. This existing road requires upgrading. It ‎will permit public access to Chester Logging Road north of the TMF without passing through the mine ‎security gate and the mine site proper‎.

- 70 -

Mine development requires three major haul roads, consisting of access to the MRA, the TMF, and the topsoil/overburden stockpile. In addition, a major intersection is required on the north side of the open pit to tie together the exit from the pit with the pit bypass road, the ramps to the ore stockpiles, and the crusher and truck shop ramps. Approximately 24.7 kilometres of new six metre wide service roads are required to access all site facilities, including many shorter spurs to dam locations, and perimeter roads around the TMF and the east side of the MRA. The site layout includes three major watercourse crossings. Roads are designed with a crossfall from side to side (as opposed to a central crown), such that the runoff from the entire road surface will be discharged to another developed drainage area on one side of the road, such as the processing plant site, the reclaim water pond basin, the TMF, MRA, Polishing Pond, or the open pit itself.

The power supply for the Côté Gold Project site will be delivered at 115 kV by the new 44 kilometres overhead line from Hydro One's Shining Tree Junction. Upstream of the Shining Tree Junction is an idle 118 kilometres 115 kV line fed from Timmins Tie Station (TS) which has been refurbished and restrung. The Independent Electricity System Operator (IESO) has completed a system impact assessment (SIA) and determined that the proposed connection to its power grid is technically feasible, that the system has sufficient capacity, and that it met the in-service date of Q3 2023. The calculated electrical load for the Côté Gold Project is as follows:

• 61 MW maximum demand load.

• 54 MW average demand load.

• 98% lagging (inductive) power factor.

This calculated load is based on the current electrical load list, and includes two electric shovels, mine dewatering, all ancillary loads, and a 10% allowance for growth during detailed design. Hydro One has allocated a total of 72 MW of capacity to the Côté Gold Project. Emergency backup power will be available from four diesel standby generators, sized to provide essential power to the process and ancillary electrical equipment. The four 1 MW prime gensets will be located in the main substation area, will be 600 V rated and will be stepped up to 13.8 kV to be distributed around the site.

Environmental Considerations

An EA was completed for the Côté Gold Project under Canadian Environmental Assessment Act, 2012. An EA Decision Statement was issued by the Federal Minister of Environment and Climate Change Canada on April 13, 2016, and a Notice of Approval was issued by the MOECC on December 22, 2016. The Côté Gold Project has undergone optimizations since the 2015 environmental assessment, including:

- 71 -

• Relocation and reduction of the TMF to minimize overprinting of fish-bearing waters, reduction of the Côté Gold Project footprint, improved Project economics, reduction in the need for watercourse realignments, and the avoidance of effluent discharges to the Mesomikenda Lake watershed.

• Reduced open pit size.

• Modifications to the processing plant.

• Reduction in transmission line voltage and re-routing of the transmission line; a Provincial Class EA for the 115 kV transmission line was completed in 2019.

IAMGOLD has conducted additional baseline studies within the boundaries of the new TMF and topsoil/ overburden stockpile, and new transmission line alignment, to infill the physical, biological, and human environment characterizations conducted previously. These additional baseline data, together with design information for the site configuration, were used to prepare the Environmental Effects Review ("EER") for the Côté Gold Project, for submission to the Canadian Environmental Assessment Agency ("CEAA") and the Ontario Ministry of Environment, Conservation and Parks ("MECP"), thus informing the regulatory agencies of changes or improvements to the 2015 environmental assessment. On October 19, 2018, the CEAA confirmed that the proposed Côté Gold Project changes are not considered new designated physical activities and therefore a new EA is not required. On November 9, 2018, the MECP also confirmed its concurrence with the EER report conclusion that the proposed changes to the undertaking result in no new net effects.

Perimeter embankment dams, raised in stages, will be used for tailings management.

Water quality will be monitored in the process water (before and after cyanide destruction) prior to discharge to the TMF. Water quality will also be monitored in the TMF settling pond and in the seepage collection system. Groundwater quality will be monitored at wells to be installed downgradient of the TMF seepage collection system to confirm that seepage from the TMF is being captured in the seepage collection system.

Closure of the Côté Gold Project is governed by the Mining Act (Ontario) and its associated regulations and codes. IAMGOLD has a filed closure plan in accordance with the legislative requirements dated August 2021. This plan details measures for temporary suspension, care and maintenance, and closure of the Côté Gold Project, including determining financial assurance and development milestones ‎required to reclaim the Côté Gold Project in accordance with the closure plan.‎

The NDMNRF requires financial assurance for implementation of the closure plan. A closure cost ‎estimate is included in the operating cost estimate of the Côté Gold Project closure plan and is ‎reviewed and updated as required‎.

Permitting Activities

In 2022 at the Côté Gold Project, permitting efforts continued with several permits received, including an amendment to the Fisheries Act Authorization approving the removal of three fish-bearing ponds and an update of planned complementary offsetting measures, and other permits required to construct fish habitat. IAMGOLD applied to the Ontario Ministry of the Environment, Conservation and Parks for initial entry into the Emissions Performance Standards program to further compliance with its environmental obligations including establishing an emissions baseline for the Côté operation.

The estimates for restoration and closure costs are prepared by knowledgeable individuals and are subject to review and approval by government authorities where regulated. Site closure costs are charged against a provision accumulated during the production phase. As at December 31, 2023, IAMGOLD estimated these obligations at US$69.6 million for the Côté Gold Project.

Social Considerations

IAMGOLD has actively engaged Indigenous, local and regional communities, as well as other stakeholders, to gain a better understanding of their issues and interests, identify potential partnerships, and build social acceptance for the Côté Gold Project. Stakeholders involved in Project consultations to date include those with a direct interest in the Côté Gold Project, as well as local and regional communities identified‎ through the baseline studies.

The involvement of stakeholders will continue throughout the various Project stages. The range of stakeholders is expected to evolve over time, to reflect varying levels of interest and issues.

As part of the Provincial conditions of EA approval, IAMGOLD developed and submitted a Community Communication Plan to the responsible Provincial ministry, outlining its plan to communicate with stakeholders through all phases of the Côté Gold Project.

IAMGOLD worked collaboratively with the community of Gogama on the development of a socio-economic management and monitoring plan to manage potential socio-economic effects of the Côté Gold Project (both adverse and positive). The plan was developed in 2020 and implementation began in 2021.

An understanding of the Indigenous communities potentially interested in the Côté Gold Project was first developed through advice from the Province of Ontario to the previous property owner Trelawney in a letter dated August 19, 2011, and through advice from the CEAA (now the Impact Assessment Agency) based on information provided by Aboriginal Affairs and Northern Development Canada (now Indigenous and Northern Affairs Canada). IAMGOLD sought further direction from both Provincial and Federal Crown agencies on the potentially affected communities.

Based on Federal and Provincial advice and information gathered through engagement activities, IAMGOLD engaged a range of Indigenous groups during the preparation of the EA. IAMGOLD has continued to engage the identified communities through information sharing (e.g., newsletters, notices, invitations to open houses, various permit applications), and has focused on actively engaging affected communities identified in the Federal Decision Statement and ‎Provincial Conditions of Approval. The Côté Gold Project is located on Treaty 9 Territory, on the traditional lands of ‎Mattagami First Nation and Flying Post First Nation, and within the traditional harvesting area of the Métis ‎Nation of Ontario, Region 3. IAMGOLD signed Impact Benefit Agreements with the Mattagami First Nation and Flying Post First ‎Nation in April 2019 and with the Métis Nation of Ontario (Region 3) in May 2021‎.

As part of the Provincial and Federal conditions of EA approval, IAMGOLD developed and submitted an Indigenous Consultation Plan to the responsible government departments, outlining the Côté Gold Project's plan to consult with identified Indigenous groups throughout all phases of the Côté Gold Project. IAMGOLD consulted all identified Indigenous groups as part of the development of the Indigenous Consultation Plan, as required.

IAMGOLD committed to work with the communities of Mattagami First Nation and Flying Post First Nation to collaboratively develop a socio-economic management and monitoring plan to manage potential socioeconomic effects of the Côté Gold Project (both adverse and positive). This plan was developed collaboratively with the communities and implementation began in 2021. The monitoring committee, comprised of members of each community and IAMGOLD, meets quarterly.

Capital and Operating Costs

1.Capital Costs

As of December 31, 2023, construction progress at Côté Gold was estimated to be 98% complete, while ‎overall project progress was approximately 95.5% complete which includes demobilization of construction ‎teams and facilities. Since commencement of construction, $2.786 billion of project expenditures has ‎been incurred. The total estimated remaining cost to complete construction and commission the Côté ‎Gold Project up to achieving first gold is $179.0 million (± 5%) bringing the total project expenditures up ‎to first gold to $2.965 billion on an incurred basis. Post first gold, completion of certain infrastructure and ‎earthworks projects are estimated to be $40 million (± 5%).

- 73 -

The estimated capital expenditures related to operations for 2024, excluding capital waste stripping, total ‎‎$145 million (± 5%). Capitalized waste stripping is estimated to be $50 million (± 5%) for the year‎.

2.Operating Costs

Operating costs are based on the Côté Gold Report. ‎Total operating costs over the LOM are estimated to be $4,073 million. Mining (excluding CWS) and processing costs represent 35% and 46% of this total, respectively. Average operating costs are estimated at $17.48/t of processed ore.

Total Operating Costs Over the LOM IAMGOLD Corporation - Côté Gold Project
Cost Area	Total (US$ million)	Percent of Total
Mining Operating (excl CWS)	1,445	35
Processing	1,856	46
G&A	772	19
Total	4,073	100

Average Unit Operating Costs IAMGOLD Corporation - Côté Gold Project
Cost Area	US$/t of processed ore
Mining (excl CWS)	6.20 (8.49 if CWS included)
Processing	7.97
G&A	3.31
Total	17.48

Mining quantities were derived from first principles and mine phased planning to achieve the planned production rates. Mining excavation estimates were based on geological studies, mine models, drawings, and sketches. Mine costs generally increase with time as the pit increases in depth and the MRA increase in height.

Process operating costs estimates were developed from first principles, metallurgical test work, IAMGOLD's salary/benefit guidelines, and recent vendor quotations, and benchmarked against historical data for similar processing plants. The process operating costs include reagents, consumables, personnel, electrical power, and laboratory testing. The consumables accounted for in the operating costs include spare parts, grinding media, and liner and screen components. Process operating costs over the LOM are estimated to average $7.97/t of processed ore. G&A costs averaging $3.31/t of processed ore over the LOM were developed from first principles and benchmarked against similar projects.

- 74 -

Royalties, that varies depending on gold price, the amount of expenditure that can be deducted and the source of the ore within the pit, and management fees and allowances to meet commitments to stakeholders, total $483 million over the LOM or average $2.07/t processed. The amount of royalties paid are dependent on the gold price assumptions and the ability of IAMGOLD to deduct certain expenditures when calculating the royalties.

Reclamation and closure costs are estimated to total $83 million, distributed annually from early in the mine life until post-closure. This is based on a detailed closure cost estimate adjusted to include an allowance for security bond fees and a credit at the end of mine life to account for the estimated salvage value of equipment and materials. This was also adjusted for inflation to bring the estimate to 2022 dollars.

- 76 -

• OMT is levied at a rate of 10% on taxable profit in excess of C$500,000 derived from mining operations in Ontario. OMT is deductible in calculating Federal income tax and a similar resource allowance is available as a deduction in calculating Ontario income tax. OMT is not affected by harmonization, accordingly, it is administered provincially by Ontario.

• IAMGOLD's taxation model was relied on for the calculation of income and mining taxes applicable to the cash flow.

Recent Updates

In 2023, exploration activities continued to further delineate and expand the Gosselin zone located immediately to the northeast of the Côté Gold Project deposit and test selected targets along an interpreted favourable deposit corridor. Approximately 24,600 metres of DD was completed in 2023.

On February 2, 2023, IAMGOLD reported assay results from its 2022 delineation diamond drilling program at the Gosselin zone including: 342.2 metres grading 1.99 g/t Au, 313.0 metres grading 1.29 g/t Au and 181.0 metres grading 1.50 g/t Au. During the fourth quarter, IAMGOLD reported additional assay results from its 2023 drill program with highlights including: 300.8 metres grading 1.40 g/t Au in GOS23-134, 240.0 metres grading 1.53 g/t Au in GOS23-136 and 500.8 metres grading 0.72 g/t Au in GOS23-144.. Drill intercepts obtained helped to highlight a prospective corridor at depth measuring up to 850 metres in strike length that remains to be tested between the Gosselin West Breccia and the Côté deposit hydrothermal breccia.

In 2024, IAMGOLD plans additional expansion and delineation diamond drilling to expand and increase the confidence of the existing resource especially at depth and between the current Gosselin and the Côté deposits. In addition, IAMGOLD is advancing various technical studies, including a metallurgical testing sampling program, the establishment of the environmental baseline and mining optimization studies for the inclusion of Gosselin resources into the Côté Gold life-of-mine plans.

Taca Taca Royalty

The Company holds the Taca Taca Royalty through its wholly-owned subsidiary, Nova. On October 7, 2020, Nova entered into royalty purchase agreements with arm's length private parties ‎pursuant to which Nova acquired an existing 0.24% NSR Royalty on the Taca Taca Project, owned by First Quantum, for $12.75 million. Closing of the acquisition of the Original Taca Taca Royalty was effected in ‎November 2020. On January 10, ‎‎2021, Nova entered into royalty purchase agreements with existing shareholders of Nova, ‎pursuant to which Nova acquired an existing 0.18% interest in a 1.5% NSR Royalty on the Taca Taca Property ‎‎owned by First Quantum for approximately $20.0 million, increasing Nova's interest to an aggregate 0.42%.

Summary

Project Description, Location and Access

The Taca Taca Property is a porphyry copper-gold-molybdenum deposit located in the arid Puna (Altiplano) region of Salta Province, in northwest Argentina. The proposed project involves the open pit mining and flotation processing of copper ore from this deposit for a period of 32 years.

The Taca Taca Property is located approximately 230 km west of the city of Salta and 55 km east of the Chilean border. The nearest population centre is the village of Tolar Grande (population of approximately 150), which is 35 km east of the Taca Taca Project site.

The Taca Taca Property is situated at a median elevation of 3,625 metres above sea level, in an environment with sparse flora and fauna and on the edge of an expansive salt lake (salar). The climate at Taca Taca is arid, with an annual precipitation of approximately 40 mm/year and an evaporation rate of 2,500 mm per year. Temperatures range from minus 3°C to 22°C, with January being the warmest month and July being the coldest month. Wind speeds typically range from 3.8 m/s to 23.2 m/s, blowing predominantly from the northwest. Although winds are generally strong, particularly during the winter months, development and operational activities could be carried out year-round. The Taca Taca Property is located in a seismically active region.

The Taca Taca Property is 100% owned by First Quantum through its Argentinian subsidiary Corriente Argentina SA ("CASA"). The Taca Taca Property and associated areas of interest are held in a composite package of mining rights consisting of 82 concessions. Two of the mining concessions have a 50% ownership with third-party groups, though these are not over commercially material portions of the known deposit. The Taca Taca Property is subject to a 3.0% provincial government royalty and a 1.5% third-party NSR Royalty.

The proposed project has the following material components:

• a multi-phased open pit mine extending to an ultimate depth in excess of 700 m;

• surface stockpiles for marginal ore, and separately for auriferous material not in the Mineral Reserve, but which could be economically processed in the future;

• a mining waste dump, located to the east of the open pit, on the surface of the adjacent salar (the Salar de Arizaro);

• a processing plant site which is located adjacent to the open pit, in an area of relatively flat topography sheltered from the prevailing wind direction;

• a concentrator for the processing of copper mineralisation by flotation, with primary recovery of gold (and silver¹) into the concentrate;

______________________________________________________
¹ Silver (Ag) is considered immaterial to the economic value of the Taca Taca Project ‎and hence Ag grades have not been reported in the Taca Taca Project ‎mineral resource and reserve estimates, nor accounted for in the Mineral Reserve economic analysis.

- 78 -

• separation of copper and molybdenum concentrates;

• ramp-up of the processing rate from 30 Mt in the first year, to 40 Mtpa for the next five years, followed by a 50 Mtpa rate for one year, and then to an eventual rate of 60 Mtpa from Year 8;

• a nearby tailings storage facility ("TSF") located within an embayment of the Salar de Arizaro process water storage ponds;

• borefields for the supply of fresh and saline water;

• overland pipelines between the concentrator and the TSF, and between borefields and the plant site;

• surface haulage and internal access roads;

• mine services workshops and equipment wash-down facilities;

• construction offices, mine administration and accommodation facilities;

• storage space and a rail load-out facility for copper and molybdenum concentrate products;

• parts and consumables, reagent and explosives handling and storage facilities; and

• as additional infrastructure, there are roads for transporting supplies into the Taca Taca Project site, a railway for transporting concentrates and supplies, and a high voltage electric transmission line.

As the Taca Taca Project continues through the engineering phase and into the development and operations phases, production aspects may change, and components reviewed and varied to suit then current circumstances and new information.

History

The Taca Taca Property deposit was discovered in the late 1960s. Lumina Copper Corp.‎‎ ("Lumina") acquired an interest in the Taca Taca Project when shareholders of Global Copper Corporation ‎approved a corporate reorganisation in August 2008. This ultimately resulted in the acquisition by Lumina ‎of 100% of the shares of CASA and a 100% interest in the Taca Taca Project.‎

In August 2014, First Quantum acquired Lumina and its primary asset, the Taca Taca Project. Since that ‎time, First Quantum has completed detailed reviews of the deposit geology, mineralogy and ‎processing amenability, in addition to assessing development options for the Taca Taca Project. From ‎‎2015, First Quantum has conducted water exploration drilling and aquifer pump tests to confirm ‎sustainable groundwater supply sources for the Taca Taca Project and has been progressing with ‎environmental and engineering phase studies. The Taca Taca Project engineering and feasibility phase remains in ‎progress.‎

Readers should refer to the Taca Taca Report for a summary of the historical exploration and ‎associated work that has occurred with respect to the Taca Taca Project.‎

Geological Setting and Mineralisation

As further described in the Taca Taca Report, the Taca Taca Project has porphyry copper-gold-‎molybdenum mineralisation located in the southern half of a 50 km long Ordovician batholith, ‎which forms the Sierra de Taca Taca mountain range. The Taca Taca mineralisation is hosted ‎by plutonic rocks of granitic composition together with lesser dacite, dolerite, and rhyolite ‎intrusions. The porphyry is characterised by kilometre-scale zones of hydrothermally-altered ‎rocks that grade from a central potassic core to outer phyllic and argillic zones. Phyllic ‎alteration is most pervasive across the deposit and is closely associated with mineralisation.‎

- 79 -

Mineralisation is comprised of supergene (chalcocite) and hypogene (chalcopyrite) zones. A ‎sub-surface leached horizon of varying thickness overlies the supergene and hypogene ‎mineralisation. Mineralisation is disseminated and in fractures, veinlets, and quartz vein ‎stockworks.‎

The leached horizon is largely depleted of copper mineralisation except for a zone of chalcocite-‎rich ore perched within the leached material to the east of the deposit. In addition, a zone of ‎supergene gold mineralisation, close to surface, is present above the thickest portion of leached ‎material.‎

Hypogene copper sulphides are mostly chalcopyrite with lesser bornite, chalcocite, covellite, ‎and digenite. The mineralisation is broadly zoned with a chalcopyrite-bornite-molybdenite core ‎yielding to a stronger pyritic halo around the outer edges.‎

Supergene zones are mostly secondary sulphides formed by enrichment within a discontinuous ‎blanket underneath the leached cap. Supergene mineralisation is often variably mixed with ‎hypogene mineralisation and is often due to deep-seated alteration along structures and host ‎rocks. Fine-grained black chalcocite and lesser covellite are the main secondary copper ‎sulphides.‎

Mineralisation remains open at depth and around several peripheral areas of the deposit.

Exploration

Copper mineralization at Taca Taca was first reported by Fabricaciones Militares in the late 1960s. Historical exploration included multiple drill programs and geophysical surveys across the Taca Taca area under various operators.

Surface outcrop mapping was active during most of the exploration phase, supported by excavator trenching and road cuts. CASA and Riomin Exploraciones, S.A. ("Rio Tinto") also undertook comprehensive geochemical sampling of soils and rock outcrops over and peripheral to the deposit, resulting in a dataset with approximately 100 m by 100 m spatial coverage. Much of the property geological information has been derived from drill hole logging, interpretation of assay data, geophysical surveys, and the mapping of outcrop and trenches.

Following acquisition of the Taca Taca Project, First Quantum completed several small-scale data collection programmes to ensure that supporting datasets were complete and of high quality. In 2014, New-Sense Geophysics carried out a helicopter-borne magnetic and radiometric survey on behalf of First Quantum. A total of 4,424.1 survey line kilometres of data was collected at a 300 m spacing across the property. Results were used to support anomaly delineation, structural evaluation, and the identification of lithological trends. Geochemical sampling campaigns of in-situ soils at a 500 m by 500 m grid spacing were also completed around the outer extents of the concessions. In 2019, a high-resolution topographic survey was acquired.

Additional work between 2020 and 2022 continued on evaluation of extensions of the deposit and nearby targets. Additional high-resolution ground based geophysics were collected over the deposit area, and a targeted brownfield drilling campaign was completed in 2022.

Drilling

Most of the Taca Taca drilling activities were carried out prior to First Quantum's acquisition of Taca Taca. First Quantum verified the drill hole core logging data by check re-logging and check assaying. A total of 484 drill holes, for 172,031 metres, have been drilled in support of defining the mineralization extents. Of these, 44 holes were drilled outside of First Quantum owned concessions for the purpose of freshwater exploration and for collecting geotechnical data for proposed infrastructure sites.

- 80 -

Prior to acquisition by Lumina, five different companies had carried out exploratory drill campaigns on the property. Earliest drilling of the copper porphyry was by Falconbridge in 1975. Results from three diamond holes showed a relatively thick, metal depleted, leached cap. No further drilling was conducted until 1994 when Glencore plc tested for shallow gold-copper bearing veins to the north of the porphyry and remnant copper mineralization within the porphyry leached cap.

Between 1996 and 1997, BHP drilled 35 diamond holes (including two re-drills) at an approximate 400 m by 400 m grid spacing into the porphyry. Results partially delineated the supergene dominant zone of mineralization directly below the leached cap.

During 1998 and 1999, CASA drilled 14 diamond holes and 80 RC holes focusing on shallow and exotic copper mineralization peripheral to the porphyry. Rio Tinto conducted two separate campaigns in 1999 and 2008. Drilling in 1999 mainly targeted shallow oxides within the porphyry leached cap (seven RC holes) and exotic mineralization below the Salar de Arizaro (two RC holes). In 2008, Rio Tinto returned to test for deeper hypogene copper-molybdenum mineralization at the core of the porphyry with eight diamond holes (including two re-drills).

Lumina completed a total of 283 drill holes (137,671.5m) across the Taca Taca area during a 2010 to 2012 drill campaign. This comprised 155 diamond drilled (DD) holes and 128 reverse circulation (RC) holes, and included fifteen geotechnical holes and four water monitoring holes. Most drill holes targeted the deeper porphyry and were completed along a set of east-west trending sections, on a nominal 150 m by 150 m grid spacing. As standard procedure, drill core was logged for lithology, weathering, alteration, mineralization and structure. Diamond holes were also logged for geotechnical data, including core recovery, rock quality, fracture frequency and vein density, and vein angles. Samples were taken every 10 m for point load index tests and for density measurements.

During 2019, an additional four diamond holes were drilled by First Quantum as twins to Lumina drill holes to provide additional samples for metallurgical test work from material representing early plant feed. Drilling and sampling procedures for these four drill holes were aligned to those used by Lumina. Samples were analysed using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) for 48 elements, including copper and molybdenum, and fire assay with AAS finish for gold.

In 2022, First Quantum drilled a further fourteen diamond drillholes for 6,302m on rear mine brownfield targets and deposit extensions. The results are still under evaluation. In addition to this, a further nine diamond drillholes, 1800m total, were drilled during 2022 as part of an infrastructure sterilization program.

Further drilling was undertaken to explore for fresh water and to collect geotechnical data at proposed infrastructure sites.

Sampling, Analysis and Data Verification

Detailed information on sampling, analysis, and data verification for drill holes used in the Mineral Resource estimate can be found in the Taca Taca Report, available on SEDAR+ under First Quantum's profile. This includes all holes drilled between 1996 and 2019. No written record of sample preparation, analytical methods, or analytical results is available for holes drilled prior to this, by Falconbridge or Glencore.

QA/QC results indicated that adequate controls were in place and that assay results are reliable. Sample values are believed to be representative of the prevailing mineralization and thus suitable for use in the Mineral Resource estimate. Historic data with limited records mostly provides additional information to the deposit peripheries and is not considered to pose a risk to the quality of the estimate.

Mineral Processing and Metallurgical Testing

Metallurgical test work by Lumina was completed over a period of three years from April 2010. Up until 2019 there was no additional laboratory work undertaken, although technical reviews done by First Quantum in 2017 included an assessment of the potential for gold recovery during the Taca Taca Project pre-strip phase.

A primary reference document for the preparation of the Taca Taca Report was the Preliminary Economic Assessment Report ("PEA Report") dated May 24, 2013 (with an effective date of April 9, 2013). The PEA Report summarised the original test work findings as follows:

• the ore is of moderate competency and hardness, and is amenable to grinding in a conventional semiautogenous grind (SAG) - ball milling circuit, with pebble crushing and regrinding; and

• average recoveries would be approximately 90% for copper, 57% for molybdenum and 64% for gold

First Quantum's 2017 review of the available test work data highlighted several deficiencies and some uncertainty around metallurgical performance due to the variability of copper mineralisation styles, especially in relation to the extent of mixed mineralisation (i.e., oxidised, ‎and tarnished ores). In addition, most of the test work had been conducted using tap water; limited test work using brine solutions indicated reduced recoveries and lower concentrate grades.

During the course of reviewing the test work data variability, and as part of the Mineral Resource modelling by First Quantum, distinct data groupings (clusters) were identified for recovery and copper concentrate grade related to mineralogy, Cu and Fe assay grades.

During 2019, four metallurgical holes were drilled from which ten samples were selected to represent the first five years of operations. These samples along with brine solutions from the Salar de Arizaro, and brackish water from Valle de Arizaro and Valle de las Burras, were sent to the ALS laboratories in Kamloops, Canada.

The test work programme included comminution work for mill sizing, flotation work in brine and brackish water to define recoveries and concentrate grades in locked cycle test work, sedimentation and filtration test work for thickener and concentrate filter sizing, and environmental test work to determine the potential for acid generation from tailings. This test work programme was completed in 2020.

The comminution test work highlighted the toughness of the rock types at Taca Taca and indicated the need for secondary crushing to achieve the ultimate design throughput of 60 Mtpa in two milling trains.

Flotation test work indicated high mass pulls to rougher concentrates using brine solutions in rougher flotation. Brackish or fresh water would be required in the cleaner flotation circuit to enable high pH values to be achieved for pyrite depression; otherwise low concentrate grades and low recoveries would occur in this circuit. Nonetheless, copper recoveries were generally lower than obtained in the previous test work campaigns using tap water.

The data generated from the recent locked cycle test work was combined with the variability test work results obtained in the previous test work campaigns to estimate recoveries and concentrate grades for the distinct ore types and the different ranges of copper and pyrite present. These estimates were coded into the Mineral Resource model for adoption in future mine production scheduling and cashflow modelling.

From the test work results and mine production schedules the following average life of mine recoveries using brine solution in rougher flotation are anticipated:

• copper recovery of 85.0% to a concentrate grade of 25.3% Cu

• molybdenum recoveries of 40% to a concentrate grade of 47% to 50% Mo

• gold recoveries to the copper concentrate of 60%, with a grade of approximately 4.5 g/t Au

Mineral Resource Estimate

First Quantum produced a revised estimate in December 2019 incorporating the following improvements:

• Geological domains were identified from weathering, rock-type, alteration, and dominant mineralisation characteristics. These formed the basis of a new 3D geological model, including interpretations of an updated base of leach, a partial leach zone, and a perched copper horizon within the leached cap. Sequential copper assay data was corrected as per a rate of oxidation study and then used to guide domain classification. Domain geostatistics were also updated accordingly.

• A deposit-scale fault position was updated based on visual and core photography verification.

• The Mineral Resource estimate was reclassified based on confidence in the estimates as per kriging efficiency, regression slope, and degree of geology and slope continuity. It was constrained to within 100 m from the current design pit limits.

Data from a total of 435 diamond and reverse circulation drilled holes, for a total of 75,803 analysed samples, was included in the Mineral Resource estimate. Drill data (logging and sampling) was combined with surface geology mapping and geology modelling to provide defined zones of mineralisation.

The grade estimates were completed in the following stages:

• domains of mineralisation were defined via comprehensive data analysis

• domains were spatially represented as wireframe models and coded into a block model

• sample chemical data was geostatistically assessed for each domain and then estimated using ordinary kriging

• copper, gold, molybdenum, silver, iron and sulphur grades were estimated

Block model grade estimates were validated using summary statistics, visual validations, swath plots and comparison with previous estimates. Estimates were classified as Measured, Indicated and Inferred Mineral Resources. Mineral Resource classification was guided by confidence in the grade estimates and underlying geology model. In addition, drill grid spacing, quality assurance and quality control and an ultimate pit shell were used to guide the classification limits of mineralisation having reasonable prospects for eventual economic extraction.

The block model estimates were reported at a 0.13% copper equivalent (Cu_eq) cut-off grade, which is consistent with the Mineral Reserve estimate. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

The October 2020 Mineral Resource statement is listed in Table 1. The Mineral Resource inventory is inclusive of the Mineral Reserve inventory.

Mineral Reserve Estimate

A maiden Mineral Reserve estimate was produced for Taca Taca in Q3 2020 (Table 2). The mine plan was developed using the Measured and Indicated Mineral Resource, whilst the Inferred Mineral Resource was allocated to waste. Mining assumes conventional open pit operations using truck-and-shovel technology. The estimated Mineral Reserve was determined using metal prices of US$3.00/lb for copper, US$12.00/lb for molybdenum, and US$1,200/oz for gold, with a supporting production schedule derived from the ore and waste mining inventory within a practical pit design produced from a selected pit optimisation shell.

The actual marginal cut-off grade for the Mineral Reserve varies according to the copper recovery assigned to the various mineralogical groupings. However, the overall average marginal copper cut-off grade is in the order of 0.13% Cu_eq. An elevated cut-off grade of 0.20% Cu_eq applies to the plant feed inventory for the production schedule.

Table 2: Taca Taca Mineral Reserve statement, as at October 30, 2020

As part of the ultimate pit design for the Taca Taca Project, there is a small area in the northwest that crosses over into a joint venture concession. This encroachment amounts to approximately 1.7 Mt of ore at an average grade of 0.38% Cu.

The production schedule for the Taca Taca Project is set out in the Taca Taca Report.

Features of the mining and production schedule are as follows:

• Mining commences in Year-3 starting with the pre-strip period, whilst processing commences in Year-1. The Taca Taca Project life (processing years) is 32 years.

• 240.1 Mt of waste is mined in the three-year pre-strip period, during which time 17.4 Mt of ore is mined onto a stockpile for subsequent active and longer-term reclaim.

• The total material mined over the life of operations amounts to 4,543.0 Mt (1,737.0 Mbcm) of which:

  • 1,758.5 Mt is ore with average grades of 0.44% Cu, 0.012% Mo and 0.09g/t Au, and

  • 2,784.5 Mt is waste

• The overall life of mine strip ratio (waste tonnes: ore tonnes) is 1.6:1.

• The direct feed ore to the plant is 1,390.4 Mt at an average grade of 0.50% Cu, whilst 57.1 Mt at an average grade of 0.43% Cu is ore reclaimed from active stockpiles, and 311.0 Mt at an average grade of 0.15% Cu is ore (marginal ore) reclaimed from longer term stockpiles (mostly in Years-27 to 32).

- 84 -

• The total ore mined includes 39.0 Mt of ore grading 0.46% Cu from the near-surface "leached cap", of which over 15 Mt is mined to stockpile during the pre-strip years. Most of this ore is then processed over the following three years.

• There is a small area in the north west of the ultimate pit design that crosses over into a joint venture concession. The encroachment occurs between Years-5 and 15 and involves 1.7 Mt of ore and 47.5 Mt of waste.

• The Inferred Mineral Resource that is mined as waste amounts to 69 Mt at an average grade of 0.31% Cu (i.e., about 2.5% of the total waste mined). This material is encountered in the mining schedule after Year-6 and following completion of mining phases 1 and 2.

• The crusher feed ramps up from Year-1 at 30 Mt, to 40 Mt in Year-2, at which level it remains until Year-6. The feed rate then rises to 50 Mt in Year-7, and thereafter to 60 Mtpa until Year-32.

• In terms of total plant feed (after mining dilution/recovery):

  • the average copper grade is 0.72% Cu for the first six years when processing at up to 40 Mtpa,

  • then 0.45% Cu to Year-27 when processing at up to 60 Mtpa, and

  • finally 0.15% Cu for the remaining five years of Project life when reclaiming from longer-term stockpiles

• Before the final five years of marginal ore reclaim, the total plant feed is 1,476.3 Mt at an average grade of 0.50% Cu.

• The annual average copper metal production to Year-6 is 227.0 kt, and ranging between 97.5 kt and 275.2 kt. Thereafter, the annual average is 200.4 kt, and ranging between 72.5 kt and 271.1 kt (ignoring the final year of processing). In terms of life of Taca Taca Project totals:

  • 1,362.0 kt of copper is recovered in the first six years,

  • then 4,869.3 kt of copper to Year-27,

  • and finally 341.8 kt of copper for the remaining five years of Project life when reclaiming from longer-term stockpiles

• The annual average molybdenum metal production to Year-6 is 2,205 t, and ranging between 1,434 t and 2,912 t. Thereafter, the annual average is 2,776 t, and ranging between 1,745 t and 4,147 t (ignoring the final year of processing).

• The annual average gold recovered into concentrate to Year-6 is 106.3 koz and ranging between 90.9 koz and 134.1 koz. Thereafter, the annual average is 92.9 koz, and ranging between 45.7 koz and 156.6 koz (excluding the final year of processing).

• Of the total 6,573.1 kt of copper recovered over the Taca Taca Project life, only 5,535 tonnes (0.08% of the total) of this would be attributable to ore mined within the adjoining joint venture concession.

- 85 -

Mining Operations

The Taca Taca deposit grades, geometry, and depth make it suitable for conventional, large-scale, bulk open pit mining methods involving blasthole drills, diesel hydraulic excavators, electric shovels and off-highway haul trucks.

Open pit mining would proceed in phases from an initial starter pit, supplying pre-strip development waste for site infrastructure and construction, and ore onto stockpile for process plant commissioning. The average and maximum material movements over this three-year timeframe are 32.9 Mbcm and 43.3 Mbcm, respectively. There is a pronounced peak in material movements over the next ten years as the first three pit phases are completed and mining proceeds into the fourth phase. The average and maximum material movements over this period are 91.9 Mbcm and 95.7 Mbcm, respectively. Thereafter, the average and maximum material movements reduce to 42.3 Mbcm and 65.2 Mbcm, respectively.

Subject to infill drilling and further mine planning assessments, a small satellite pit immediately to the north of the design pit could be mined during the operations phase, although this is not currently part of the Mineral Reserve inventory.

The detailed mine planning as disclosed in the Taca Taca Report included conventional optimisation processes, phased and ultimate pit designs, surface layout planning and life of mine production scheduling. At the outset, conventional Whittle Four-X software was used to determine the optimal pit shell, operating with a sulphide flotation plant to produce separate copper and molybdenum concentrates. The copper concentrate would contain gold.

The optimisation was completed on a maximum net return basis (undiscounted) and with recoveries of copper into concentrate based on defined mineralogical groupings or clusters. Fixed (conservative) recovery values were used for molybdenum and gold. The optimisation process also considered open pit slope design criteria provided by a geotechnical consultant, in addition to mine operating costs derived from first principles and processing/G&A costs determined on a similar basis.

Processing and Recovery Operations

The Taca Taca processing feed would comprise a mix of supergene and hypogene ores with initial feed sourced mainly from supergene zones. Supergene ore is mostly secondary copper sulphide mineralisation (chalcocite) with some primary copper sulphides (chalcopyrite), and minor oxide copper minerals. Hypogene ore is comprised of more than 50% primary copper sulphides. Consequently, the plant feed will always contain significant amounts of secondary sulphides and some tarnished primary sulphides.

Supergene mixed ores would be encountered during the initial processing years, to be followed by increasing quantities of hypogene ore as the open pit deepens. The "leach" cap at surface is auriferous but is mostly barren of copper mineralisation². The auriferous material would be separately stockpiled for future evaluation of the economics of gold recovery.

The proposed processing method follows the porphyry copper-molybdenum (Cu-Mo) concentrator flowsheets typical in South America. Milling and rougher flotation would be performed in brine, sourced from the adjacent salar. Cleaner floatation would be undertaken in fresh/brackish water, sourced from offsite borefields.

The processing facilities are designed for an initial throughput of 30 Mtpa in Year-1, then 40 Mtpa in Years-2 to 6, then 50 Mt in Year-7, and finally 60 Mtpa from Year-8.

Ore will be subject to primary crushing followed by secondary crushing and SAG and ball milling to produce a milled product size of 80% passing 180 µm. Two milling trains will be installed, each comprising a 28 MW SAG mill and two x 22 MW ball mills (for 60 Mtpa).

______________________________________________________
² There are discrete zones (i.e., metallurgical domains) of "perched" copper and gold mineralisation in the near surface "leach" cap.

- 86 -

A rougher flotation circuit will produce a rougher flotation concentrate which will be dewatered by thickening, reground to 80% passing 30 µm and re-diluted with good quality water prior to cleaner flotation.

The addition of sodium hydrosulphide (NaHS) is proposed as a means of improving the recovery from the oxidised and mixed ores; it will sulphidise the oxidised and tarnished mineral surfaces and assist in flotation. Facilities will be provided for NaHS addition to the circuit; it is expected to be beneficial for approximately 22% of the ore feed.

Copper and molybdenum concentrates would be separated from the bulk cleaner concentrate, filtered and dispatched to off-site smelters.

Ore would be delivered from the mine by haul trucks and crushed in four primary crushers located on surface. Following primary crushing, the proposed processing plant would comprise:

• secondary crushing, to reduce the SAG mill feed size

• conveying to a coarse ore stockpile with a live capacity of 12 hours

• SAG and ball milling of crushed ore, with size classification by means of hydrocyclones

• a gravity recovery circuit on the ball mill cyclone underflow for coarse gold recovery

• pebble crushing on scats generated from the SAG mills

• rougher and scavenger flotation of cyclone overflow slurry with controlled sulphidisation flotation (using NaHS) for oxidised and tarnished supergene ores

• thickening of flotation tails

• pumping of thickened tailings to the TSF

• potential reclaim of decant water from the TSF for usage within the process³

• dewatering of rougher concentrates, to remove brine

• regrind of dewatered rougher concentrates in a high intensity grinding (HIG) mill, followed by dilution in fresh water

• cleaner flotation of the rougher concentrates to improve the copper grade, with cleaner tails being recycled to the rougher flotation circuit or to final tails

• Cu - Mo separation of the bulk cleaner concentrates in a molybdenum flotation circuit

• dewatering of copper concentrates by thickening and filtration, followed by bulk transportation to offsite smelters

• dewatering of molybdenum concentrates by thickening, filtration and drying, followed by bagging and transportation to off-site smelters

______________________________________________________
³ The current process plant water balance assumes that there will be no reclaim from the TSF.

- 87 -

• reagent make-up and dosage systems to support the milling and flotation operations

• water reticulation systems

• compressed air systems to support instrumentation and for automatic valve activation.

An average of 985,500 wet tonnes of copper concentrate is expected to be generated annually at an average grade of 25.3% Cu, along with 6,200 tonnes of molybdenum concentrate at a grade of 47% to 50% Mo.

Gold would be recovered to the copper concentrate through flotation. Coarse gold recovery would be enhanced by the addition of gravity concentrators.

Flotation tailings would be dewatered in thickeners and the thickened slurry pumped to a TSF located approximately 5 km from the process plant, within an embayment of the Salar de Arizaro.

A gold recovery circuit for the treatment of the auriferous leach cap is not proposed at this stage. This material would be stockpiled separately, subject to further test work during the early phases of operations and could be reclaimed and treated at a later date if deemed economic to do so.

Infrastructure, Permitting and Compliance Activities

Tailings Storage and Water Reclamation

An upstream raised TSF is planned to be located in a natural embayment of the Salar de Arizaro (i.e., the Salar de Taca Taca), located to the north of the processing plant site. The ultimate capacity is approximately 1.37 Bm³ and could be expanded through further lifts. The site is almost entirely enclosed by the natural land mass and would only require a relatively low height (25 m plus an additional 3 m of freeboard), short length embankment at the entrance to the salar.

The starter embankment would be constructed as an initial waste rock bund, and then upstream raised in continuous stages using cycloned tailings.

Flotation tailings slurry would typically be at a slurry density of 32% solids and would be discarded to tailings at a thickened density of 55% to 60% solids. Two tails lines, each with two stages of centrifugal pumps would be installed to deliver tailings to the TSF, with spigots arranged around the facility's periphery. Water runoff from the site and from sediment collection ponds would be pumped to the tailings thickener and, subject to further engineering analysis, excess water then recycled back to the plant.

Power and Water Supply

The total power demand for the Taca Taca Project is expected to be in the range of 180 MW to 240 MW at a processing rate of 60 Mtpa. A preferred power supply and transmission route has been identified involving 122.5 km of new transmission line and a new switching station to connect to an existing 345 kV line that extends through northern Argentina and into Chile. A preliminary design and estimates have been produced by a specialist consultant to support the development of the ESIA required for the power supply infrastructure.

The proposed new transmission line will connect the site to the national grid and enable the Taca Taca Project to source its entire electricity supply requirements through a long-term power supply agreement with an electricity supplier, to be determined through a competitive tender process. First Quantum has identified options to source 100% of its electrical energy requirements from renewable sources. Further alternatives exist, if required, to source a portion of the energy requirements from natural gas power plants in Salta and regionally.

- 88 -

In the arid environment characterising the Taca Taca Project site, local and regional borefields will be developed to supply a combination of high and low salinity water for the Taca Taca Project. Brine water from the adjacent salar is intended for use in milling and rougher flotation, comprising approximately 72% of the estimated 6,318 m3/hour make-up water required for processing. The balance of the processing water supply is intended to be fresh or brackish water abstracted from regional borefields.

Fresh water supply investigations to date have now focussed the search and drilling investigations to four regional basins located at 30 km to 50 km distance from the Taca Taca Project site. The water supply status of the Taca Taca Project is summarized in the Taca Taca Report.

Contemporary with the ongoing investigations, a specialist consultant has assisted with the specification of bore design and estimated numbers, bore spacing at each borefield source, and the nomination of pumping rates. A capital cost estimate for the bore pumps and pipelines has been completed by First Quantum, considering the number of bores required, the drilling depth, bore pumps, the pipeline distances and the pumping head.

Road and Rail Access

Existing public roads provide access to the Taca Taca Project site. However, a bypass of an existing road is planned to avoid a section with narrow switchbacks and another section which is subject to seasonal weather disruptions. A preferred deviation has been selected and would require an approximate 26.5 km length of new road construction. In addition, there is an 18.5 km length of existing road to be diverted around Tolar Grande, and a 31 km length of existing road to be diverted around the Taca Taca Project site.

The Taca Taca Project is located approximately 5 km from an existing railway line that connects Salta with Mejillones, Chile. First Quantum expects that this railway will be used for copper concentrate transport to a port at Mejillones Bay, for subsequent shipment to smelters globally. Construction of a new rail spur, a new maintenance and repair facility for locomotives and railcars, adjacent to the concentrate load-out facility, and rehabilitation across a significant length of the railway will be required. Engineering of the railway line is now being addressed in some detail and high-level discussions have been initiated with the owners of respective sections of the rail corridor.

First Quantum envisages that the cost of upgrading the existing railway formation would, ordinarily, be borne by the separate railway owners and that this cost would be recovered by them in the concentrate and other freight charges levied on First Quantum. In the Taca Taca Project capital cost estimates, however, it is assumed that the comprehensively itemised costs estimated for First Quantum by a specialist consultant, will be included as owner's costs. The cost of the required rolling stock and the concentrate load-out facility are similarly included in First Quantum's capital cost ledger.

Port for Concentrate Export

Potential concentrate export shipping ports in Mejillones Bay have been visited by First Quantum's representatives and preliminary discussions held with the port owners.

First Quantum envisages that the cost of upgrading and expanding one of these ports would be at the expense of the port owner, who would then recoup that cost through a concentrate handling charge levied on First Quantum. In the Taca Taca Project capital cost estimates, however, it is assumed that First Quantum would bear the estimated cost for port upgrades and/or expansion works.

Environmental and Social Summary

Detailed environmental baseline data collection began in 2016. A Project Alternatives Analysis and a separate Project Description document were completed in 2018 to complement the Taca Taca Project ESIA. The ESIA was submitted to the authorities in February 2019. First Quantum has subsequently filed documents responding to an ESIA review and observations made by the provincial Secretariat of Mining.

- 89 -

Social Capital Group has assisted First Quantum with socioeconomic studies including a socioeconomic baseline for the ESIA, as well as an identification of stakeholders.

Project Approvals

The primary permit required for the development of the Taca Taca Project is the Environmental and Social Impact Assessment (Informe de Impacto Ambiental, ESIA), to be approved by the Secretariat of Mining of the Salta Province. This ESIA must cover the main Project sites including mine, process plant, TSF, and associated facilities.

First Quantum submitted the Taca Taca Project ESIA to the authorities in 2019. A response to the submission was received from the Secretariat of Mining including observations and requests for clarification or more information. Initial responses were submitted to the authorities in 2020, and detailed supplementary studies on tailings and waste rock management were completed and submitted to the authorities in 2022. First Quantum anticipates receiving the ESIA approval in 2024 with subsequent proceedings for construction and operations permits along with necessary approvals to follow. After final approval, the ESIA must be updated and resubmitted to the authorities every two years.

A second ESIA was submitted separately in 2021 to the Energy Secretariat of Salta Province, for the 345 kV transmission line to connect the Taca Taca Project to the national electrical grid. In November 2022, the Salta Production Minister signed Resolution 191/2022, approving the environmental pre-feasibility for the transmission line development. The 345kV line still requires detailed construction permits, but the main environmental aspects have been approved. A third ESIA was submitted in 2021 to the Salta Road Administration for the proposed bypass road construction for the Taca Taca Project, and approval is underway.

The Taca Taca Project will also require approval from the Water Resources Secretariat of Salta Province of a concession for water supply development and use. The current water supply definition programme (Phase III) is intended to develop all of the detailed information that will be required to include in a water exploitation permit application. The Phase III water investigation programme was suspended in 2020 due to the COVID-19 pandemic but resumed in 2021. First Quantum reported that the Phase III groundwater exploration campaign was successfully completed during Q2 2023, with eighteen pumping wells constructed and tested, obtaining positive results. The initial water use permit applications were submitted during the second quarter of 2023 and granting of the concessions are expected to follow the ESIA approval.

Other administrative authorisations, detailed construction and operating permits will be required, particularly from the Municipality of Tolar Grande and provincial authorities in the course of development and operation of the Taca Taca Project. First Quantum has also filed updated ESIA documents and received approvals to proceed with the ongoing field activities. As part of the ESIA process First Quantum has undertaken socioeconomic studies including a socioeconomic baseline, as well as identification and engagement of stakeholders and social actors.

Capital and Operating Costs

A capital cost estimate was produced for the PEA Report, to a stated level of accuracy of between -25% and +35%. This comprehensive itemisation was reviewed by First Quantum, benchmarked where possible and adjusted accordingly. In particular, new information was included for such as the initial mining pre-strip and mining equipment purchase costs, power supply/transmission costs, water supply costs and rail infrastructure costs.

The updated capital cost estimate, at this stage of the Taca Taca Project engineering phase (Q3 2020) is:

• total initial capital spend over a three year construction phase (including an average 15% contingency) of US$3,274.8 million, split between:

  • US$2,636.7 million of direct costs

- 90 -

• US$638.1 million of indirect costs

• total expansion capital spend (including an average 15% contingency) of US$308.1 million, split between

  • US$223.9 million of direct costs

  • US$84.2 million of indirect costs.

General and administration operating costs, process operating costs and metal costs (i.e. product transport, refining charges and royalties) as set out in the PEA Report were reviewed, benchmarked and updated. Mining and process operating costs were estimated from first principles.

The overall average unit operating costs are:

• mining ore and waste = US$1.69/t

  • ore mining, excluding the pre-strip period = US$1.82/t

  • waste mining, excluding the pre-strip period = US$1.45/t

• stockpile reclaim = US$0.74/t reclaimed

• processing = US$4.69/t processed

• rail load-out infrastructure and water supply tariff = US$0.08/t processed.

An economic analysis in the form of a basic, pre-tax cashflow model was produced to support the Mineral Reserve estimate, and in order to demonstrate an overall positive cashflow for mining and processing over the life of the Taca Taca Project. The initial development capital and expansion capital costs are included in the analysis for completeness. The model is described in the Taca Taca Report.

The revenues in the cashflow model set out in the Taca Taca Report are calculated from the following metal prices:

• copper = US$3.00/lb (US$6,614/t)

• molybdenum = US$12.00/lb (US$26,455/t)

• gold = US$1,500/oz.

The Taca Taca Project is cashflow positive from Year-2 and payback on the initial development capital is in Year-9. The undiscounted cashflow for the Mineral Reserve production schedule is US$17,306.3 million, with an NPV reflecting an 8% discount rate equal to US$3,428.8 million. The internal rate of return is 17.4%.

A Monte Carlo simulation on the Mineral Reserve cashflow model was carried out to assess the discounted value of the Taca Taca Project; 10,000 iterations were simulated for a number of cashflow variables, over a specified range of values for each. Assuming an 8% discount rate, the simulation indicated a 70% probability that the NPV would be in excess of US$3,000 million and a 72% probability that the IRR would be in excess of 16%.

Exploration, Development and Production

The PEA Report describes the conceptual development of the Taca Taca Project as envisaged by its previous owners, and included technical information sufficient for First Quantum to review and assess its own options. More specifically, the detailed capital and operating costs set out in the PEA Report formed the basis for review, benchmarking and adaptation by First Quantum for its own economic analysis, to a level that First Quantum considers appropriate for the Taca Taca Project at its current stage.

- 91 -

Further to the Taca Taca Project review and assessments described above, First Quantum has identified its preferences for the scale and extents of open pit mining and ore processing, and for the location of required infrastructure items. Furthermore, technical work has progressed on power and water supply logistics, freight and product transport options, and on designing improved road access into the Taca Taca Project area.

In addition to resuming the Phase III water supply investigations and confirmation of borefield sustainability, a scope of continuing engineering phase work includes:

• additional Mineral Resource drilling, sampling and analysis, including infill, extensional and sterilisation targets

• mine and civil geotechnical investigations, in conjunction with seismicity investigations

• optimisation of the process plant layout and the concentrate load-out facilities

• further confirmatory metallurgical test work, not critical for the current processing flow sheet and plant design

• further infrastructure planning for power reticulation

• optimisation of the tailings delivery methodology and the potential for decant water return

• selection of a suitable location for the Taca Taca Project camp and related infrastructure

• review of waste landfill options and locations.

DIVIDENDS

Metalla's long-term dividend goal is to pay out a target rate of 50% of the annualized operating cash flow of the Company.
