Cautionary Note to United States Investors with Respect to Mineral Resources

National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") is a rule of the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Technical disclosure contained in this AIF has been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the CIM Definition Standards). These standards differ from the requirements of the U.S. Securities and Exchange Commission ("SEC"). Accordingly, Mineral Resource and Reserve information contained in this AIF may not be comparable to similar information disclosed by domestic United States companies subject to the SEC's reporting and disclosure requirements.

Alternative performance measures in this document such as "cash cost", "AISC" and "free cash flow" are furnished to provide additional information. These non-GAAP performance measures are included in this AIF because these statistics are used as key performance measures that management uses to monitor and assess performance of the DeLamar Project, and to plan and assess the overall effectiveness and efficiency of mining operations. These performance measures do not have a standard meaning within IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS. As the Company has yet to commence production, the equivalent historical non-GAAP financial measure is $0.

Cash costs include site operating costs (mining, processing, site G&A), refinery costs and royalties. While there is no standardized meaning of the measure across the industry, the Company believes that this measure is useful to external users in assessing operating performance.

Site level AISC include cash costs (see description above) and sustaining capital, but excludes head office G&A and exploration expenses. The Company believes that this measure is useful to external users in assessing operating performance and the Company's ability to generate free cash flow from current operations.

Free cash flows are revenues net of operating costs, royalties, capital expenditures and cash taxes. The Company believes that this measure is useful to the external users in assessing the Company's ability to generate cash flows from the DeLamar Project.

Unless otherwise indicated, all references to "$" in this AIF are to U.S. dollars and all references to "C$" or "CAD$" in this AIF are to Canadian dollars.

The following table reflects the low and high rates of exchange for one United States dollar, expressed in Canadian dollars, during the periods noted, the rates of exchange at the end of such periods and the average rates of exchange during such periods, based on the Bank of Canada daily exchange rates for 2019, 2020 and 2021.

On July 9, 2020, Integra effected a 2.5 to 1 consolidation of its Common Shares (the "Consolidation").

Unless otherwise noted or inconsistent with the context, references to Integra or the Company in this AIF are references to Integra Resources Corp. and its subsidiaries.

The following diagram illustrates the intercorporate relationships among Integra and its subsidiaries, as well as the jurisdiction of incorporation of each entity.

Integra is a mineral resources company engaged in the acquisition, exploration and development of mineral properties in the Americas. The primary focus of the Company is the advancement of its DeLamar gold and silver project (the "DeLamar Project"), consisting of the neighbouring DeLamar Deposit and Florida Mountain Deposit in the heart of the historic Owyhee County mining district in south western Idaho.

The Company appointed Mr. Timothy D. Arnold as Vice President, Project Development, in January 2019. Mr. Arnold, a Reno-based, Professional Mining Engineer, came to Integra with over 30 years of experience in mine project development, mine permitting and mine operational management on various projects in the western USA. Mr. Arnold was subsequently appointed COO in November 2019.

The former Idaho Governor C.L. "Butch" Otter joined the Company's Board in September 2019. Gov. Otter is a businessman who served as the 32nd Governor of Idaho from 2007 to 2019. Gov. Otter served as Lieutenant Governor from 1987 to 2001 and in the United States Congress from 2001 to 2007. Before devoting his career full-time to serving the people of Idaho in public office, Gov. Otter spent more than 30 years as a business leader including 12 years as President of the Idaho-based Simplot International.

On August 16, 2019, the Company closed an offering of 14,490,696 special warrants (the "Special Warrants") at an issue price of C$0.86 per Special Warrant for gross proceeds of C$12,461,999. The Company filed a short form prospectus and converted the Special Warrants into 14,490,696 free trading Common Shares, for no additional consideration, in August 2019.

On November 25, 2019, the Company closed a non-brokered offering with Coeur Mining, which consisted of the issue of 5,760,236 Common Shares at an issue price of C$1.15 per Common Share for gross proceeds of approximately C$6,624,270. In connection with the investment, Coeur Mining and Integra entered into the Coeur Investor Rights Agreement. The Coeur Investor Rights Agreement provides Coeur Mining with participation rights to maintain its pro rata Common Share ownership in Integra for two years and the right to appoint two members to a newly formed technical committee of Integra so long as Coeur Mining continues to own at least 2.4% of Integra's Common Shares.

On December 4, 2019, the Company closed a brokered offering, which consisted of the issue of 21,999,500 Common Shares (including exercised over-allotment option) at an issue price of C$1.15 per Common Share for gross proceeds of approximately C$25,300,000 under a short form prospectus.

On November 5, 2019, the Company announced that it had paid the remaining C$4,500,000 owed to Kinross USA pursuant to a secured promissory note. This payment represents payment in-full for all amounts owing under the secured promissory note and all obligations under the DeLamar Purchase Agreement with Kinross USA have been fully performed. As a result, Kinross USA released its security on 25% of the shares of DeLamar Mining Company.

In June 2019, Integra completed an updated Mineral Resource estimate for the DeLamar Project, which includes the DeLamar and Florida Mountain Area deposits (the "2019 Technical Report").

The Mineral Resources update incorporated approximately 30,000m in 93 drill holes of new infill and extensional drilling completed at the DeLamar Project since Integra acquired the DeLamar Project in November 2017, along with over 250,000m of drilling conducted by Kinross and its predecessors. The updated Mineral Resource showed a substantial conversion of Inferred Mineral Resources to M&I ounces. This reflected the data added to the DeLamar Project through the successful confirmatory drilling, comprehensive relogging of historical drill holes and continued compilation of historical geological information.

Please see "DeLamar Project" section below for details on the current Mineral Resource and Reserve estimate included in the "DeLamar Report".

In September 2019, Integra announced the results of a maiden 2019 PEA on the DeLamar Project. The 2019 PEA was based on the updated Mineral Resource estimate in the 2019 Technical Report.

Please see "DeLamar Project" section below for details on the current pre-feasibility study ("PFS") included in the "DeLamar Report".

In January 2019, Integra announced that it had entered into an option agreement with Nevada Select Royalty Inc. ("Nevada Select"), a wholly owned subsidiary of Ely Gold Royalties Inc. ("Ely Gold") to acquire Nevada Select's interest in a State of Idaho Mineral Lease (the "State Lease") encompassing the War Eagle gold-silver Deposit ("War Eagle Property", "War Eagle Mountain" or "War Eagle") situated in the DeLamar District, southwestern Idaho. The War Eagle Property has a history of high-grade mining in the late 1800s/early 1900s as well as high-grade exploration drilling in the late 1980's. Upon exercise of the option, Nevada Select will transfer its right, title and interest in the State Lease, subject to a 1.0% NSR royalty on future production from the deposit payable to Ely Gold, to the DeLamar Mining Company ("DMC"). Under the option agreement, Integra will pay Nevada Select $200,000 over a period of four years in annual payments.

In February 2019, Integra announced the acquisition of a highly prospective trend of multiple epithermal centers 6km to the northwest of the DeLamar Project, a trend now referred to as the "BlackSheep District", "BlackSheep Area" or "BlackSheep". The BlackSheep District to the northwest of the DeLamar Project is comparable in geographical size to both the DeLamar and Florida Mountain Area deposits combined. As a result of its findings in the BlackSheep District, and in advance of a more substantial district scale exploration program, the Company staked approximately 15 square km of additional claims.

The Company drilled approximately 22,250m from January 2019 through December 2019 at the DeLamar and Florida Mountain Area deposits and the War Eagle Property. Most of this drilling involved extracting core to support metallurgical testing, the results of which were used in the 2019 PEA. The Company's exploration program shifted to Mineral Resource expansion at the Florida Mountain Deposit Area adjacent to the known Mineral Resource envelope as well as testing of the north-south mineralized trend. The Company also initiated an exploration program at the War Eagle Property. In addition to the drill program, the Company completed extensive geochemistry, geophysics, soil sampling and historical data review to delineate potential drill targets for Mineral Resource expansion and discovery at the DeLamar Project.

The Company continued to proactively engage local stakeholders with a series of formal and informal meetings focused primarily in Owyhee and Malheur Counties. The Company's goal with these meetings was to promote a long-lasting relationship built on clear and comprehensive disclosure between Integra and the neighbouring stakeholders, in order to maintain transparency and to encourage confidence in its business practices and ethics. Groups met included residents, businesses, ranch and landowners, elected officials and others.

Local initiatives participated in during 2019 included the Jordan Valley School Science Fair, the Owyhee County Historical Society Outpost Days, local school field trips, Owyhee Field Days, the Owyhee and Junior rodeos as well as the Spurs & Spikes Charity Fundraiser. Several site visits occurred over the course of the year, with stakeholders from Owyhee County, Malheur County and elected officials having an opportunity to observe Integra's operations and ask questions on the Company's plans for the future.

For the safety of all employees, the Company closed its corporate office (Vancouver, BC) in mid-March as a result of the COVID-19 pandemic. One of the most impacted activities at the corporate level during the COVID-19 pandemic was the ability to travel due to travel bans and safety risks. The Company, however, remained extremely active on the investor relations and marketing fronts through virtual media forums both with investors and at multiple industry conferences. The Company has since re-opened its corporate office.

On February 6, 2020, the Company announced that it had been approved for graduation from Tier 2 to Tier 1 issuer status on the TSX-V. The TSX-V classifies issuers into different tiers based on standards including historical financial performance, stage of development and financial resources. Tier 1 is the TSX-V's premier tier and is reserved for the TSX-V's most advanced issuers. As a result of the graduation to Tier 1 issuer status, the remaining 966,563 Common Shares previously held in escrow were released. The number of outstanding Common Shares did not change as a result of the escrow release.

On July 31, 2020, the Common Shares commenced trading on the NYSE American under the symbol "ITRG". The Common Shares ceased to trade on the OTCQX concurrently with the NYSE American listing. The Company continues to list on the TSX-V under the symbol "ITR".

On August 21, 2020, the Company filed a final base shelf prospectus relating to the offering for sale from time to time of up to C$100,000,000 of Common Shares, warrants, subscription receipts and units.

On September 14, 2020, the Company closed a brokered offering, which consisted of the issue of 6,785,000 Common Shares (including exercised over-allotment option) at an issue price of $3.40 per Common Share for gross proceeds of approximately $23,069,000 under a final prospectus supplement (the "2020 Public Offering"). In connection with the 2020 Public Offering, the Company entered into an underwriting agreement with the underwriters of the 2020 Public Offering (the "2020 Underwriting Agreement"). Pursuant to the 2020 Underwriting Agreement, the Company agreed to pay the underwriters 5.5% of the gross proceeds of the 2020 Public Offering, other than the issue of Common Shares to certain persons on a president's list and Coeur Mining, for which a 2.75% cash commission was paid. The 2020 Underwriting Agreement also included customary terms for transactions such as the 2020 Public Offering.

On December 30, 2020, the Company filed a prospectus supplement to qualify the distribution of up to $25,000,000 of Common Shares by way of an at-the-market offering (the "ATM"). In connection with the ATM, the Company entered into an "at-the-market equity distribution agreement dated December 30, 2020 with the agent (the "Equity Distribution Agreement"). Pursuant to the Equity Distribution Agreement, the Company agreed to pay the agent 2.75% of the gross proceeds from the sale of Common Shares under the Equity Distribution Agreement. The Equity Distribution Agreement also included customary terms for transactions such as the ATM. Proceeds from the ATM funded additional exploration drilling and provided trading liquidity to United States capital markets.

In July 2020, the Company led an effort with the Association for Mineral Exploration BC ("AMEBC") that raised over C$100,000 within the British Columbia mining community to support foodbanks that serve rural, remote, and Indigenous communities.

In December 2020, Integra organized and co-sponsored a diversity & inclusion ("D&I") workshop amongst a group of roughly 25 mining executives, with instruction led by Brooks & Nelson. The goal of this workshop was to promote D&I training amongst Integra's leadership team, as well as extend the training to a group of industry leaders.

On December 3, 2020, the Company appointed Mr. Joshua Serfass to the position of Executive Vice President, Corporate Development and Investors Relations and Mr. Mark Stockton to the position of Vice President, Corporate Affairs and Sustainability. Earlier in 2020, the Company also hired a Senior Exploration Manager, Site Controller, Permitting Manager, and Engineering Manager.

In mid-March 2020, for the safety of all employees, the Company suspended drilling and exploration activities. In mid-May 2020, the United States government declared mining an essential service; with comprehensive operational procedures in-place, which were specifically designed to mitigate the risk of disease transmission amongst essential site staff and crews, and the Company resumed drilling. The Company continues to comply with both Oregon and Idaho state government requirements regarding COVID-19. Though initially delayed due to COVID-19, all planned exploration drilling in 2020 was successfully executed.

The Company completed a total of 14,517m of exploration drilling in 2020, including 9,091m at the Florida Mountain Area, 3,674m at War Eagle, 1,083m at the DeLamar Area, and 669m at BlackSheep Area.

Integra drilled 20 drill holes at the Florida Mountain Area specifically targeting high-grade shoots. Of those 20 drill holes, 13 intersected significant high-grade gold-silver mineralization in most cases well outside of the existing Mineral Resource boundaries under the 2019 PEA.

Integra's exploration team identified 7 high-grade vein structures, with an aggregate length of 7,000m that appear similar in size and orientation to the historically productive high-grade Trade Dollar - Black Jack vein system. Most historic underground production stemmed from the Trade Dollar - Black Jack vein, while the remaining 6 veins saw limited production up until mining operations ceased with the start of World War I.

Integra refined its understanding of the controls on high-grade vein mineralization at the Florida Mountain Area in early 2020 and used this model to specifically target the higher-grade "shoots" within the several vein systems identified to date. Those higher-grade shoots are interpreted as being localized at the intersections of the North-Northwest and roughly East-West Trending fault/fracture systems. The high-grade shoots within those vein structures are localized at structural intersections, have strike length of up to 100m or more and down-dip extensions of several hundred meters, with widths of between 1m and 8m.

On February 24, 2020, the Company announced the final drill holes received from the 2019 Florida Mountain Area metallurgical sampling program, highlighting high-grade gold and silver outside of current resource boundary.

On July 29, 2020, the Company announced drilling results from its first 4 drill holes of the 2020 program at Florida Mountain. The holes intersected significant high-grade gold and silver mineralization both within and outside of the existing Mineral Resource boundary in the 2019 PEA. These drill results provided evidence that structurally-controlled high-grade veins exist below the Mineral Resource estimate in the 2019 PEA and that further drill definition could potentially be interpreted and modelled as high-grade mill feed in future economic studies. The results from the 2020 Florida Mountain Area program were incorporated in the current Mineral Resource and Reserve estimate and PFS included in the "DeLamar Report". Please see "DeLamar Project" section below.

³ Downhole thickness; true width varies depending on drill hole dip; most drill holes are aimed at intersecting the vein structures close to perpendicular therefore true widths are close to downhole widths (approximately 70% conversion ratio); Intervals reported are uncapped; Gold equivalent = g Au/t + (g Ag/t ÷ 77.70); For the intervals that were previously mined/stoped and were therefore unrecoverable and unverifiable, a grade of 0 g/t Au was inserted for compositing.

On September 24, 2020, the Company announced drilling and geophysics results from the Florida Mountain Area. 5 drill holes intersected significant high-and-low-grade gold and silver mineralization both within and below the Mineral Resource boundary in the 2019 PEA. The results from the 2020 Florida Mountain Area program were incorporated in the current Mineral Resource and Reserve estimate and PFS included in the "DeLamar Report". Please see "DeLamar Project" section below.

On December 9, 2020, the Company announced further exploration results from the 2020 Florida Mountain Area exploration program.

Drilling at War Eagle identified two parallel mineralized structures approximately 150m apart with strike lengths of over 500m. Those principal structures host high-grade gold and silver mineralization associated with quartz-pyrite veinlets within rhyolite breccias and brecciated volcano-sediments. The mineralization identified to date within the volcanics is considered to be within the diffuse cap which sits above the modelled high-grade veins within the underlying granite. The broad distribution of mineralization delineated by the soil geochemical anomalies indicates considerable lateral dispersion of mineralization within the permeable volcanic cap, possibly from a structure several hundred meters east of the known mineralized structures. All holes drilled in 2020 at War Eagle intersected these mineralized zones to varying degrees, highlighting the presence of high-grade gold silver concentrations in the form of 100m to 200m strike lengths in steeply plunging shoots.

⁴ Downhole thickness; true width varies depending on drill hole dip; most drill holes are aimed at intersecting the vein structures close to perpendicular therefore true widths are close to downhole widths (approximately 70% conversion ratio); Intervals reported are uncapped; Gold equivalent = g Au/t + (g Ag/t ÷ 77.70); For the intervals that were previously mined/stoped and were therefore unrecoverable and unverifiable, a grade of 0 g/t Au was inserted for compositing.

On February 6, 2020, the Company announced drilling results from War Eagle, including 5.40 g/t Au and 45.85 Ag (5.99 g/t AuEq) over 3.05m at War Eagle in 150m step-out.

On November 19, 2020, the Company announced that it had intersected high-grade mineralization 400m north of 2019 drilling results in step-out drilling at War Eagle Mountain. This zone was first identified by soil geochemistry and confirmed by drilling in 2020. The structure is largely untested and extends at least 500m in a south-southeast direction.

Exploration drilling began at BlackSheep in late 2020. Two shallow drill holes were completed at the Georgianna target in 2020 to better define the structures controlling mineralization.

On February 18, 2021, the Company announced that the initial 4 drill holes (including 3 drill holes from the 2020 exploration program) from Georgianna, Milestone and Lucky Days targets within the BlackSheep District, intersected thick sections of low-sulphidation epithermal gold-silver mineralization, including several high-grade intercepts.

Drill highlights from the Georgianna targets, in the BlackSheep District, included:

> 0.66 g/t Au and 117.25 g/t Ag (2.17 g/t AuEq) over 10.67m, including 1.48 g/t Au and 351.00 g/t Ag (5.99 g/t AuEq) over 3.05m

> Broader low-grade intercepts include 0.30 g/t Au and 10.87 g/t Ag (0.44 g/t AuEq) over 41.76m

The Company intersected one of the highest-grade intercepts to date from the Milestone Deposit situated at the base of the existing resource and interpreted as indicating the location of the postulated higher-grade 'feeder zone' below, highlights included:

A large geophysical anomaly to the west of the Florida Mountain Area was defined with the 2020 IP geophysical surveys in an area that had seen very limited historic drill testing. IP has proven to be a very effective tool for target generation in the DeLamar Area district because of the association of disseminated sulfide alteration with gold and silver mineralization. The IP data provided in the Company's September 24, 2020 news release delineated an anomaly 1,200m in length to the west of the Mineral Resource estimate at the Florida Mountain Area in the 2019 PEA in an area known as Blue Gulch. This strong geophysical anomaly coincides with an arsenic ("As") and Au soil geochemistry anomaly. The results of exploration at Blue Gulch are not incorporated in the current Mineral Resource and Reserve estimate and PFS included in the "DeLamar Report".

The BlackSheep IP survey was completed in July 2020. The data delineated two linear zones of chargeability and coincident resistivity at Georgianna, one of those features coincides with an outcropping vein in the Georgianna Pit. At Lucky Days, the IP delineated an extensive (300 x 200m) zone of chargeability coincident with outcropping stock-work vein mineralization similar in appearance to the mineralization at DeLamar.

On February 6, 2020, the Company announced that soil geochemical surveys at the Florida Mountain Area delineated a 1,400m x 600m high intensity Au, Ag, As and Molybdenum ("Mo") anomaly directly to the east of the existing Florida Mountain Area Mineral Resource included in the 2019 PEA. The size of this anomaly is comparable to the main anomaly covering the existing Mineral Resource at the Florida Mountain Area in the 2019 PEA and the area has limited historic drilling which together with the presence of historic workings indicate potential for both low-grade stockwork and high-grade veins in this area.

At War Eagle, a 1,000m x 200m Au and As anomaly was delineated approximately 300m east of the area drill tested in late 2019. A large complex Au/As soil anomaly, approximately the size of the footprint over the DeLamar Area, was outlined in the BlackSheep Area.

A rock chip sampling program was completed over the outcropping vein zone at Georgianna and Lucky Days areas in the southern half of BlackSheep. The sampling delineated a 300m x 100m zone of intense stockwork vein mineralization at the Lucky Days target also in BlackSheep. Please refer to the Company's news release dated September 24, 2020 for rock sampling results.

Other than metallurgical drilling, the development activities in 2020 were not greatly impacted by the COVID-19 pandemic. The metallurgical drilling was eventually successfully completed in the calendar year 2020.

The 2020 metallurgical drill program was designed to characterize gold and silver recovery variability within the oxide and transitional mineralization at the DeLamar Project. The program sought to further optimize processing options at the DeLamar and Florida Mountain Area, and to advance the Company's metallurgical knowledge in connection with the DeLamar Report on both deposits in 2022.

On August 20, 2020, the Company announced that it had signed a Memorandum of Understanding ("MOU") with the United States Bureau of Land Management ("BLM") to facilitate the hiring of a dedicated mineral specialist in the Marsing, Idaho BLM office that will oversee future permitting work for the DeLamar Project. In accordance with the MOU, Integra will reimburse the BLM for the costs of a dedicated mineral specialist project manager in the Marsing BLM office, who shall remain at all times independent of the Company. This BLM project manager responsible for the DeLamar Project permitting work will help the BLM manage increased workloads from current and anticipated future applications for mineral notices, operations plans/amendment approvals and environmental analyses resulting from the DeLamar Project. This funding effort is intended to increase the capacity of the local BLM office to work on DeLamar Project related applications and project requests on a priority basis, while not burdening the BLM with the cost of this increased workload.

2020 saw significant efforts with respect to advancing the permitting process at the DeLamar Project. To enhance the process, Integra has maintained a focus from the outset on establishing positive partnerships with a wide selection of stakeholders. By focusing on these partnerships well in advance of submitting actionable documents to regulatory agencies, the Company intends to position itself in the best possible scenario to facilitate the permitting process in an efficient manner. Paramount to this process has been working with the BLM, the lead federal agency that the Company will engage with regarding permitting, in addition to Idaho state regulators. The MOU announced on August 20, 2020 streamlines the iterative permitting process, with the agreement allowing for an efficient communication framework between the Company and the BLM moving forward.

The ability to have initial plans reviewed for accuracy and conditionally approved by various regulatory agencies up front can add meaningful efficiencies in the permitting timeline. Being committed to transparent, straightforward, and accountable communication with stakeholders, Integra intends to facilitate a process in which the prospective mine plan being developed receives the appropriate acceptance from those stakeholders that any future development plans may impact. To this extent, actions in 2020 involving stakeholders at the regulator/agency level included:

Surface water and existing groundwater well sampling was collected in the 2^nd and 3^rd quarter of 2020. The first party air monitoring program contractor was selected and the site meteorological monitoring station became operational in early August, 2020.

The 2020 engineering plans advanced steadily, building upon the concise plans outlined in the 2019 PEA. Importantly, efforts were focussed on adding Mineral Resources included in the Mineral Resource estimate in the 2019 PEA, but had yet to be included into the mine plan provided in the 2019 PEA. While the mainstay of the 2019 PEA focussed on heap-leaching (DeLamar and Florida Mountain Area oxide and transitional mineralization) and milling (Florida Mountain Area sulfide mineralization), much of the 2020 efforts were centered in the metallurgical properties of the DeLamar Area sulfide material and high-grade transitional material. Metallurgical test work on the DeLamar Area mineralization included:

Over the course of 2020, the Company undertook several pre-feasibility and environmental baseline studies at the DeLamar Project, including geotechnical drilling and test work for pit slope design and stability.

On December 3, 2020, the Company announced the engagement of Mine Development Associates, a division of RESPEC ("MDA") as the lead consultant for the PFS at the DeLamar Project.

In response to the unprecedented circumstances surrounding the COVID-19 pandemic, several initiatives were undertaken in Idaho to support the local community during these extraordinary times. In partnership with the Jordan Valley Lions Club, Integra staff conducted weekly grocery supply trips to the Boise Valley, allowing the community's elderly and at-risk population the opportunity to stay home and avoid travelling to more populated centers. In addition, and in cooperation with several Idaho companies through an initiative titled Curds & Kindness, Integra collaborated with Idaho's dairy farmers in redirecting their excess supply of dairy products to Idaho and Oregon food banks. The excess supply stems from the lack of demand in the restaurant industry, one of the many sectors that have been severely impacted by COVID-19.

Integra implemented strict operational measures in response to the COVID-19 pandemic, which restricted contact between employees and limited non-essential access to the DeLamar Project site. When deemed necessary, particularly following periods of higher travel within the community such as following breaks and holidays, site-wide testing of the entire employee-base allowed the Company to limit COVID-19 transmission on site.

Stakeholder meetings continued throughout the year where possible, either by video conference or in socially distanced settings as the Company continued to build relationships with surrounding communities that future operations may touch.

As part as its local initiatives, the Company extended a secured $140,000 loan to a local business owner in August 2020 to complete the construction of a restaurant in Jordan Valley, the closest community to the DeLamar Project. This restaurant is the sole restaurant serving the local community and the Company's employees and contractors.

As part of Integra's Environment, Social, Governance ("ESG") commitment to prioritizing environmental stewardship at every stage of the project life cycle, the Company engaged Warm Springs Consulting of Boise, Idaho, as the consulting/engineering firm to evaluate several sustainability-driven option studies that were incorporated into the PFS.

Water treatment operations followed their regular course at the DeLamar Project, with system updates to the water treatment facility completed and in operation, allowing for more efficient water filtration and less bi-product waste creation in the process.

As a result of the COVID-19 pandemic, all corporate employees continued to work remotely from home in 2021, with some employees working periodically at the corporate head office under safe COVID-19 protection protocols. Travel bans and safety risks continued to have an impact in 2021. However, the Company was able to remain extremely active on the investor relations and marketing fronts through virtual media forums both with investors and at multiple industry conferences. Regular site visit activities in Idaho resumed in the second half of 2021 by various senior staff members.

On February 25, 2021, the Company announced the appointment of Carolyn Clark Loder to the Board.

The Company held its Annual General Meeting of shareholders on June 29, 2021. A total of 22,225,932 Common Shares were voted, representing 40.5% of the Company's then outstanding Common Shares. All of the directors were elected, and all other resolutions were approved by the Company's shareholders.

On August 11, 2021, the Company approved a revised Code of Business Conduct and Ethics ("Code").

On September 17, 2021, the Company closed a brokered offering, which consisted of the issue of 6,785,000 Common Shares (including exercised over-allotment option) at an issue price of $2.55 per Common Share for gross proceeds of approximately $17,301,750 under a final prospectus supplement (the "2021 Public Offering"). In connection with the 2021 Public Offering, the Company entered into an underwriting agreement with the underwriters of the 2021 Public Offering (the "2021 Underwriting Agreement"). Pursuant to the 2021 Underwriting Agreement, the Company agreed to pay the underwriters 5.5% of the gross proceeds of the 2021 Public Offering, other than the issue of Common Shares to certain persons on a president's list and Coeur Mining, for which a 2.75% cash commission was paid. The 2021 Underwriting Agreement also included customary terms for transactions such as the 2021 Public Offering.

Pursuant to the Equity Distribution Agreement Integra entered into in December 2020, the Company made the following sales under its ATM in 2021:

On November 10, 2021, the Company released its first ESG report. See "Social and Environmental" section below for further details on the ESG report and ESG initiatives in 2021.

The Company announced on February 9, 2022 the results from its PFS. See "Pre-Feasibility Study" section below for PFS highlights and "DeLamar Project" section for further details.

The Company changed its presentation currency as of December 31, 2021 from the Canadian dollar to the US dollar to better reflect that the Company's business activities and most of the Company's assets and liabilities are held in its US subsidiaries hence denominated in US dollars.

Some of Integra's contractors, namely the drilling contractors and assay laboratory, experienced labour shortages as a result of the COVID-19 pandemic. This impacted drilling productivity in 2021 and greatly delayed assay result turnaround from the assay laboratories.

The Company completed a total of 28,109m of core drilling in 2021, including 18,177m at the Florida Mountain Area, 4,537m at the DeLamar Area, 2,227m at BlackSheep District and 3,167m at War Eagle.

The Company also completed a total of 2,377m of RC drilling in 2021, including 1,524m at BlackSheep, 594m at the DeLamar Area, and 259 m at Milestone target (DeLamar Area).

The 2021 drilling program was not included in the current Mineral Resource and Reserve estimates included in the DeLamar Report. Please see "DeLamar Project" section below.

Drilling at the Florida Mountain Area in 2021 was dual-focused, including follow-up exploration on the high-grade shoots and structures below the existing Mineral Resource and expanding the existing low-grade Mineral Resource through drilling geochemical and geophysical anomalies to the east and west of the existing Mineral Resource.

To further define the high-grade resource potential at the Florida Mountain Area, the Company decided to initially focus on three of the seven known high-grade vein structures. By focusing on these three structures, which include the Alpine Vein, Stone Cabin-Tip Top Vein and the remnant Trade Dollar - Black Jack vein. The 2021 drilling program demonstrated the continuity of grade within the deeper high-grade vein systems which could become the focus of a concerted underground drill program if warranted in the future.

Drilling also took place in the Florida Keys area, a large geochemical anomaly located immediately to the east of the Mineral Resource that has seen limited drilling. The Florida Keys geochemical anomaly is of similar strength and size to the existing Mineral Resource estimate footprint at the Florida Mountain Area.

On August 31, 2021, the Company announced drilling results from the Florida Mountain Area covering a strike length of 400m in the north-south direction and further display the strong vein continuity present at the Florida Mountain Area.

On November 4, 2021, the Company announced drilling results from the Florida Mountain Area. The results included multiple high-grade drill results at the Florida Mountain Area as well as long widths of mineralization within the existing Mineral Resource envelope at the Florida Mountain Area that exceed the current grade of the Florida Mountain Area Mineral Resource.

On February 24, 2022, the Company announced drilling results from the Florida Mountain Area outside of the current Mineral Resource and Reserve estimate included in the DeLamar Report.

The goal of the 2021 drilling program at War Eagle was to test the northern extensions of the structures identified during the 2019 and 2020 drill programs.

The core drill campaign at BlackSheep focused on the Georgianna, Milestone and Lucky Days targets. BlackSheep is host to extensive areas of sinter and opaline silica cut by high-level epithermal veining and brecciation. Due to the shallow level of erosion at BlackSheep, very limited exploration drilling completed by previous operators was shown to be too shallow to properly evaluate the potential for high-grade vein style mineralization.

Drilling at Lucky Days in 2021 indicated the presence of a potentially extensive zone of shallow low-grade mineralization, further drilling in this area is planned for 2022.

On October 21, 2021, the Company announced drilling results from the ongoing metallurgical program at Sullivan Gulch located east-southeast of the DeLamar Area.

On March 17, 2022, the Company announced drilling results from an exploration drill program at Sullivan Gulch located east-southeast of the DeLamar Area.

Thorough QA/QC protocols are followed on the DeLamar Project, including insertion of duplicate, blank and standard samples in the assay stream for all drill holes. The samples are submitted directly to AAL in Reno, Nevada for preparation and analysis. Analysis of gold is performed using fire assay method with atomic absorption ("AA") finish on a 1 assay ton aliquot. Gold results over 5 g/t are re-run using a gravimetric finish. Silver analysis is performed using ICP for results up to 100 g/t on a 5 acid digestion, with a fire assay, gravimetric finish for results over 100 g/t silver.

See "DeLamar Project - Sampling, Analysis and Data Verification" below with respect to the DeLamar Report.

The development activities in 2021 were not materially impacted by the COVID-19 pandemic.

The Company commenced its condemnation drilling program in 2021 and drilled a total of 1,122m in the year.

The Company commenced its metallurgical drilling program in 2021 and drilled a total of 1,197m in the year.

Metallurgical drilling at Sullivan Gulch has been designed to further optimize and potentially include additional mineralized non-oxide material from Sullivan Gulch in future studies.

Integra submitted and received approval on plans of study required to conduct baseline surveys for the following resources: aquatic resources, cultural resources, wildlife, vegetation, wetlands seeps and springs, soils, surface and groundwater, and geochemical characterization. Baseline surveys were conducted on all of these resources, except geochemical characterization. Geochemical samples were selected to initiate geochemical characterization of mine features as well as installation of a PM 10 monitor to provide site-specific baseline air conditions. Baseline survey reports have been submitted to the agencies and are under review. These baseline reports will serve as the basis for the forthcoming draft Environmental Impact Statement that will be developed subsequent to the submittal of the Mine Plan of Operations and Notice of Intent.

Integra completed the installation of the groundwater monitoring well network in order to initiate the collection of baseline data to support the Point of Compliance necessary for the operation of the mine. Initial coordination with the following agencies has occurred: BLM, Idaho Department of Lands ("IDL"), IDEQ, Idaho Department of Fish and Game ("IDFG"), IDWR, U.S. Army Corps of Engineers, Office of Energy and Mineral Resources ("OEMR"), as well as outreach to the following tribes: Fort McDermitt Paiute and Shoshone Tribes of the Fort McDermitt Indian Reservation, Nevada and Oregon, Shoshone-Paiute Tribes of the Duck Valley Indian Reservation, Shoshone-Bannock Tribes of the Fort Hall Reservation, and Burns Paiute Tribe. Coordination with the Office of Species Conservation has initiated to begin early discussions on potential concerns regarding greater sage grouse.

On February 24, 2022, the Company announced that it received positive approval from the BLM through an environmental assessment authorizing an underground development and exploration drill program at the Florida Mountain Area.

Integra's engineering team continued from the 2020 metallurgical test program on both heap leach and mill ores. Numerous bottle roll and column leach tests, including load/permeability tests, were conducted on Heap Leach materials from both the Florida Mountain and DeLamar Area. Many milling tests were also completed including grind size and flotation work, comminution testing, high pressure griding rolls ("HPGR") test work, regrinding and leaching optimization, and solid liquid separation tests. Basic minerology was also completed to look at clay species in the heap leach feeds, and to better understand the non-oxide mill ores. Several metallurgical holes were drilled to provide non-oxide material from Sullivan Gulch for Albion testing and engineering, based on promising results from a scoping level study. Further Albion testing will start in early 2022.

Several trade off studies were completed in 2021 to determine best processing methods for higher grade heap leach ores, and mill ores. Various throughputs were also investigated. Gravity concentration and leaching of the flotation tailing were both examined for the Florida Mountain Area non-oxide ore. It was determined equivalent ultimate recoveries could be achieve by flotation only, so the gravity circuit was eliminated from the design. Leaching of the flotation tailing proved to be uneconomic. Mining planning, heap leach pad and stacking plan design, process and tailing facilities design all progressed in 2021 for the PFS. The PFS contemplates a combined stage 1 and 2 35,000 metric tonnes per day ("mtpd") heap leach process at 80% passing 12.7mm (0.5 inch) in stage 1 that will process oxide and mixed ore from both the Florida Mountain and DeLamar Area, and a 6,000 mtpd mill to be constructed in stage 2 to process non-oxide ore from both deposits utilizing conventional grind, flotation, re-grinding and cyanidation of the concentrate. The PFS contemplates separate facilities to be used for the flotation tailing and the leached concentrate.

Site support initiatives included setting up the RV camp in Jordan Valley, various water management upgrades and water treatment sludge management, initiating a site safety participation card, and the design of the upgraded fuel storage systems.

On February 9, 2022, the Company announced the results of its PFS and Mineral Resource and Reserve statement on the DeLamar Project.

The PFS contemplates an open pit mine with on-site treatment of oxide and mixed ores from both the Florida Mountain and DeLamar Area via a 35,000 mtpd heap leach facility at 80% passing 12.7 mm (0.5 inch), and treatment of a portion of the non-oxide mineralization through a 6,000 mtpd mill utilizing conventional grind, flotation, re-grinding and cyanidation of the concentrate. In year 1, heap leaching of the Florida Mountain Area ore will commence, with mill construction beginning in year 1 and production starting in year 3. In year 2, oxide and mixed ore from the DeLamar Area will be mined with the non-oxide ore being accessed from the DeLamar and Florida Mountain Areas starting in year 3. In total, the DeLamar Project will process 123,483,000 tonnes of ore over a 16-year mine life producing an estimated 1,154,000 oz Au and an estimated 49,995,640 oz Ag (1,786,729 oz AuEq). The strip ratio over LOM, waste-to-ore, is 2.21.

The PFS is derived from the Company's pit-constrained Mineral Reserve estimate with an effective date of January 24, 2022 and does not include results from drilling completed in 2021. The effective date of the PFS is January 24, 2022.

The PFS includes multiple sustainability-driven initiatives to decrease the environmental footprint of the DeLamar Project, including:

The incorporation of these plans is not only crucial to lowering the DeLamar Project's greenhouse gas emissions, but they also importantly drive stronger economics for the DeLamar Project, demonstrating how mining projects can benefit economically from taking steps towards sustainability.

See "DeLamar Project" below with respect to the DeLamar Report and further details related to the PFS and Mineral Resource and Mineral Reserve statement.

In early March 2021, the Company hired a Community Affairs Manager, Ms. Emily Hendrickson. Ms. Hendrickson brings significant experience in mining-specific community relations and is playing a critical role in the Company's community outreach and in maintaining relationships with the Company's key stakeholders.

Extensive stakeholder outreach continued in 2021, and COVID-19 safety protocols were adhered to as appropriate. In 2021, the Company engaged with local residents, educators, local non-profits, conservation groups, local city & community councils and chambers of commerce, state government representatives and specific interest groups. The Company continues to build relationships with surrounding communities that future operations may touch. The Company's focus to date has been in both holding project-specific meetings, as well as attending regular community dialogue meetings where we participate as members of the community. In August 2021, the Company held its first annual "DeLamar Day" held outdoors in Jordan Valley, with roughly 180 stakeholders in attendance.

Integra began communications with Tribal Nations with current and historic ties to the lands surrounding the DeLamar Project, as well as Tribal foundations. These meetings are in addition to the important meetings between governmental agencies and Tribes, held throughout the permitting process.

On June 29, 2021, the Company announced that it had signed a memorandum of understanding with Trout Unlimited to evaluate potential future habitat reclamation projects within the Jordan Creek watershed where the DeLamar Project is located. Integra also joined the CleanTech Alliance, a Seattle-based group with over 1,100 member organizations that facilitates the generation and growth of cleantech companies and jobs across the Pacific northwest. As a member, Integra will both benefit from collaborations with companies pushing the envelope of responsible environmental practice, and also represent an important voice as a potential future producer of silver and gold, two metals critical to clean technologies. Mark Stockton, Integra's VP of Corporate Affairs & Sustainability, will serve on the board of directors for the CleanTech Alliance.

The Company completed in the third quarter of 2021 a several month-long process to identify, align, develop and create Integra's core values of "Integrity, Care, and Innovation". The process obtained 100% employee involvement across Integra and its subsidiaries, and a focus group with representation proportionate to all Integra locations held a series of meetings to finalize the process. The Company continues to work on plans that will operationalize the values in our everyday activities across our entire employee-base.

On November 10, 2021, the Company released its first ESG report, which provides a comprehensive overview of the Company's commitments, practices and performance in the areas of ESG for the year 2020. The report marks an important milestone for the Company as it seeks to establish itself as a leader in ESG in the mineral exploration and development sector.

The Company will continue its dual track strategy for 2022, consisting of exploration drilling designed to expand the Mineral Resource and Reserve base and development study and permitting work designed to de-risk the DeLamar Project.

The Company will also continue metallurgical test work and detailed engineering throughout 2022.

On the permitting front, surface, groundwater, geochemistry, wetlands, wildlife, aquatic, cultural and associated baseline studies, along with the management of these efforts, will extend throughout 2022.

The 2022 exploration program will include core and RC drilling to expand the Mineral Resource and Reserve along with soil sampling, geological mapping and prospecting. The Company anticipates the drill program to primarily focus on zones of immediate upside resource expansion potential in proximity to planned mining operations per the PFS. Some early-stage reconnaissance level exploration drilling will also be conducted.

The primary focus of the Company is the advancement of its DeLamar Project, consisting of the neighboring DeLamar Area and Florida Mountain Area in the heart of the historic Owyhee County mining district in southwestern Idaho. The management team comprises the former executive team from Integra Gold Corp. ("Integra Gold").

Integra owns no producing properties and, consequently, has no current operating income or cash flow from the properties it holds, nor has it had any income from operations in the past three financial years. As a consequence, operations of Integra are primarily funded by equity financings.

Please see "General Development of the Business - Three Year History" and "General Development of the Business - Trends and Outlook" sections above and "DeLamar Project" section below for further details on the DeLamar Project and development thereof.

Integra's business requires specialized skills and knowledge in the areas of geology, drilling, planning, implementation of exploration programs, compliance, engineering, metallurgy, economic studies, project development and permitting. To date, Integra has been able to locate and retain such professionals in Canada and the United States, and believes it will be able to continue to do so.

Integra operates in a very competitive industry and competes with other companies, many of which have greater technical and financial facilities for the acquisition and development of mineral properties, as well as for the recruitment and retention of qualified employees and consultants.

The precious metals sector is very volatile and cyclical. The sector specifically suffered significant declines from 2011 to 2019. During the same period the financial markets for mining in general, and mineral exploration and development in particular, were relatively weak. However, 2020 was a much stronger year for prices of gold and silver and for mining equities, as the price of gold reached a high, mostly fueled by the uncertainty created by the COVID-19 pandemic. Financial markets for mining have softened since, despite robust gold and silver prices. Fundamentals that have traditionally supported a strong gold price are present, but there is no certainty that the prices of gold and silver will remain high and that the financial markets for mining will remain strong.

In addition to commodity price cycles and recessionary periods, exploration activity may also be affected by seasonal and irregular weather conditions in Idaho.

Integra's operations are subject to environmental regulations promulgated by government agencies from time to time. Environmental legislation provides for restrictions and prohibitions on spills, releases or emissions of various substances produced in association with certain mining industry operations, such as seepage from tailings disposal areas, and the use of cyanide which would result in environmental pollution. A breach of such legislation may result in imposition of fines and penalties. Certain types of operations may also require the submission and approval of environmental impact assessments.

Environmental legislation is evolving in a manner that means stricter standards, and enforcement, fines and penalties for non-compliance are more stringent. Environmental assessments of proposed projects carry a heightened degree of responsibility for companies including its directors, officers and employees.

The cost of compliance with changes in governmental regulations has the potential to reduce the profitability of operations.

As of December 31, 2021, Integra had forty-eight (48) full-time employees and six (6) part-time employees.

The DeLamar Project is located in Idaho. Mineral exploration and mining activities in the United States may be affected in varying degrees by government regulations relating to the mining industry. Any changes in regulations or shifts in political conditions may adversely affect Integra's business. Operations may be affected in varying degrees by government regulations with respect to restrictions on permitting, production, price controls, income taxes, expropriation of property, environmental legislation and mine safety.

Integra has adopted a Code that is intended to document the principles of conduct and ethics to be followed by employees, consultants, officers and directors of Integra. Its purpose is to:

Integra expects all of its employees, officers and directors to comply at all times with the principles in the Code.

The Company also adopted a Safety, Environmental and Social Responsibility Policy to be followed by employees, consultants, officers and directors of Integra. Its purpose is to outline how Integra, together with its directors, officers, employees, consultants and contractors, will conduct its business in a safe and environmentally friendly manner and to the highest standards of corporate social responsibility.

The Company is subject to a number of risks and uncertainties due to the nature of its business. The Company's exploration activities expose it to various financial and operational risks that could have a significant impact on its level of operating cash flows in the future. Readers are advised to study and consider risk factors stressed below. While the Company considers the risks set out below to be the most significant to potential investors, they are not the only ones facing the Company. Additional risks and uncertainties not currently known to the Company, or that the Company currently deems immaterial, may also materially adversely affect the Company's business, financial condition, results of operations, cash flows or prospects. If any of these risks materialize into actual events or circumstances, the Company's assets, liabilities, financial condition, results of operations (including future results of operations), business and business prospects, are likely to be materially and adversely affected. In such circumstances, the price of the Common Shares could decline and investors may lose all or part of their investment. Accordingly, potential investors should carefully consider the risks set out below and elsewhere in the Company's public disclosure record before purchasing Common Shares.

The COVID-19 pandemic and efforts to contain it may have an impact on the Company's business. The Company continues to monitor the situation and the impact the virus may have on the DeLamar Project. Should the virus spread, travel bans continue, as applicable, or should one of the Company's team members or consultants become infected, the Company's ability to advance the DeLamar Project may be impacted. Similarly, the Company's ability to obtain financing and the ability of the Company's vendors, suppliers, consultants and partners to meet obligations may be impacted as a result of COVID-19 and efforts to contain the virus.

Resource exploration and development is a speculative business and involves a high degree of risk. There is no certainty that the expenditures to be made by Integra in the exploration of the DeLamar Project or otherwise will result in discoveries of commercial quantities of minerals. The marketability of natural resources which may be acquired or discovered by Integra will be affected by numerous factors beyond the control of Integra, including, but not limited to, the COVID-19 pandemic. These factors include market fluctuations, the proximity and capacity of natural resource markets and processing equipment, government regulations, including regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of minerals and environmental protection. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may result in Integra not receiving an adequate return on invested capital.

Integra will require additional funding to conduct future exploration programs on the DeLamar Project and to conduct other exploration programs. If Integra's current exploration programs are successful, additional funds will be required for the development of an economic mineral body and to place it into commercial production. In addition, Integra has fixed payment obligations but no source of revenue. The DeLamar Project requires reclamation work of approximately $2,000,000 per year for the foreseeable future, though this number is expected to decrease over time, all of which will need to be funded by Integra from available cash. The Company has limited financial resources and no operating revenue. The only sources of future funds presently available to Integra are the sale of equity capital, or the offering by Integra of an interest in its properties. There is no assurance that any such funds will be available to Integra on acceptable terms, on a timely basis or at all. Failure to obtain additional financing on a timely basis could cause Integra to reduce or terminate its proposed operations and otherwise could have a material adverse effect on its business.

The Company's ability to continue as a going concern is dependent upon, among other things, the Company continuing to establish commercial quantities of Mineral Reserves on its properties and obtaining the necessary financing to develop and profitably produce such minerals or, alternatively, disposing of its interests on a profitable basis. Any unexpected costs, problems or delays could severely impact the Company's ability to continue exploration and, if applicable, development activities. Should the Company be unable to continue as a going concern, realization of assets and settlement of liabilities in other than the normal course of business may be at amounts materially different than the Company's estimates. The amounts attributed to the DeLamar Project in the Company's financial statements represent acquisition and exploration costs and should not be taken to represent realizable value. The Company will require additional financing for the upcoming financial year in order to maintain its operations and exploration activities. These material uncertainties raise substantial doubt on the Company's ability to continue as a going concern.

The development of the Company's properties is dependent on the future prices of gold and silver. As well, should any of the Company's properties eventually enter commercial production, the Company's profitability will be significantly affected by changes in the market prices of gold and silver. Precious metals prices are subject to volatile price movements, which can be material and occur over short periods of time and which are affected by numerous factors, all of which are beyond the Company's control. Such factors include, but are not limited to, interest and exchange rates, inflation or deflation, fluctuations in the value of the U.S. dollar and foreign currencies, global and regional supply and demand, speculative trading, the costs of and levels of precious metals production, and political and economic conditions. Such external economic factors are in turn influenced by changes in international investment patterns, monetary systems, the strength of and confidence in the U.S. dollar (the currency in which the prices of precious metals are generally quoted) and political developments. The effect of these factors on the prices of precious metals, and therefore the economic viability of the DeLamar Project, cannot be accurately determined. The prices of gold and silver have historically fluctuated widely, and future price declines could cause the development of (and any future commercial production from) the DeLamar Project to be impracticable or uneconomic. As such, the Company may determine that it is not economically feasible to commence commercial production, which could have a material adverse impact on the Company's financial performance and results of operations. In such a circumstance, the Company may also curtail or suspend some or all of its exploration activities.

The Company's Mineral Resources and Mineral Reserves are estimates only and are based on estimates of mineral content and quantity derived from limited information acquired through drilling and other sampling methods and require judgmental interpretations of geology, structure, grade distributions and trends and other factors. The Company's Mineral Resource and Mineral Reserve estimates may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing and other factors. There are numerous uncertainties inherent in estimating Mineral Resources and Mineral Reserves, including many factors beyond the Company's control. Estimation is a subjective process, and the accuracy of the Company's Mineral Resource or Mineral Reserve estimate is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation of that data and the level of congruence with the actual size and characteristics of the Company's deposits. No assurance can be given that the estimates are accurate or that the indicated level of metal will be produced. Actual mineralization or geological formations may be different from those predicted. Further, it may take many years before production is possible, and during that time the economic feasibility of exploiting a discovery may change. These estimates may, therefore, require adjustments or downward revisions based upon further exploration or development work, drilling or actual production experience.

Fluctuations in gold and silver prices, results of drilling, metallurgical testing and production, the evaluation of mine plans after the date of any estimate, permitting requirements or unforeseen technical or operational difficulties may require revision of the Company's Mineral Resource and Mineral Reserve estimates. Prolonged declines in the market price of gold or silver may render Mineral Reserves containing relatively lower grades of mineralization uneconomical to recover and could materially reduce the Company's Mineral Reserves. Mineral Resource estimates are based on drill hole information, which is not necessarily indicative of conditions between and around the drill holes. Accordingly, such Mineral Resource estimates may require revision as more geologic and drilling information becomes available and as actual production experience is gained. Mineral Resources and Mineral Reserves should not be interpreted as assurances of LOM or of the profitability of future operations. There is a degree of uncertainty in estimating Mineral Resources and Mineral Reserves and of the grades and tonnages that are forecast to be mined and, as a result, the grade and volume of gold or silver that the Company mines, processes and recovers may not be the same as currently anticipated. Any material reductions in estimates of Mineral Resources and Mineral Reserves, or of the Company's ability to economically extract these Mineral Reserves, could have a material adverse effect on the DeLamar Project and the Company's business, financial condition, results of operations, cash flows or prospects.

Mineral Resources are not Mineral Reserves and have a greater degree of uncertainty as to their existence and feasibility. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no assurance that Mineral Resources will be upgraded to Proven or Probable Mineral Reserves. Inferred Mineral Resources have a substantial degree of uncertainty as to their existence, and economic and legal feasibility. Accordingly, there is no assurance that Inferred Mineral Resources reported herein will ever be upgraded to a higher category. Investors are cautioned not to assume that part or all of an Inferred Mineral Resource exists, or is economically or legally mineable.

The success of the Company depends to a large extent upon its abilities to retain the services of its senior management and key personnel. The loss of the services of any of these persons could have a materially adverse effect on the Company's business and prospects. There is no assurance the Company can maintain the services of its directors, officers or other qualified personnel required to operate its business.

Integra has no history of earnings or of a return on investment, and there is no assurance that the DeLamar Project or any other property or business that Integra may acquire or undertake will generate earnings, operate profitably or provide a return on investment in the future. Integra has no capacity to pay dividends at this time and no plans to pay dividends for the foreseeable future.

The Company is an exploration stage company and has not generated cash flow from operations. The Company is devoting significant resources to the development and acquisition of its properties, however there can be no assurance that it will generate positive cash flow from operations in the future. The Company expects to continue to incur negative consolidated operating cash flow and losses until such time as it achieves commercial production at a particular project. However, even in the event the Company undertakes development activity on a particular project, there is no certainty that the Company will produce revenues, operate profitably or provide a return on investment in the future. The Company currently has negative cash flow from operating activities.

Historically, capital requirements have been primarily funded through the sale of Common Shares. Factors that could affect the availability of financing include the progress and results of ongoing exploration at the Company's mineral properties, the state of international debt and equity markets, and investor perceptions and expectations of the global gold and/or silver markets. There can be no assurance that such financing will be available in the amount required at any time or for any period or, if available, that it can be obtained on terms satisfactory to the Company. Based on the amount of funding raised, the Company's planned exploration or other work programs may be postponed, or otherwise revised, as necessary.

The activities of the Company are subject to environmental regulations promulgated by government agencies from time to time. Environmental legislation generally provides for restrictions and prohibitions on spills, releases or emissions of various substances produced in association with certain mining industry operations, such as seepage from tailings disposal areas, which would result in environmental pollution. A breach of such legislation may result in imposition of fines and penalties. In addition, certain types of operations, including any proposed development of the DeLamar Project, will require the submission and approval of environmental impact assessments. Environmental legislation is evolving to stricter standards, and enforcement, fines and penalties for non-compliance are more stringent. Environmental assessments of proposed projects carry a heightened degree of responsibility for companies and directors, officers and employees. The cost of compliance with changes in governmental regulations has potential to reduce the profitability of operations.

There is the potential for substances or conditions existing on the DeLamar Project that would impose obligations on the Company under environment law arising from prior mining activities. The mine on the property has been in closure for approximately 15 years with only modest ongoing reclamation obligations remaining and Integra has no indication of any latent environmental damage. Nevertheless, the DeLamar Project was the source of historical mining activity going back over 100 years and any undiscovered issue existing on the property from those activities would likely be the responsibility of Integra.

Failure to comply with applicable environmental laws, regulations and permitting requirements may result in enforcement actions 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 may be required to compensate those suffering loss or damage by reason of such activities and may have civil or criminal fines or penalties imposed upon them for violation of applicable laws or regulations.

Amendments to current environmental laws, regulations and permits governing operations and activities of mining companies and mine reclamation and remediation activities, or more stringent implementation thereof, could have a material adverse impact on Integra and cause increases in capital expenditures or production costs or reduction in levels of production at producing properties or require abandonment or delays in the development of new mining properties.

Integra's mineral property interests are subject to receiving and maintaining permits from appropriate governmental authorities. In particular, prior to any development of the DeLamar Project, Integra will need to receive numerous permits from appropriate governmental authorities including those relating to mining operations, occupational health, toxic substances, waste disposal, safety, environmental protection, land use and others. There is no assurance that the Company will be able to obtain all necessary renewals of existing permits, additional permits for any possible future developments or changes to operations or additional permits associated with new legislation. Further, 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 activities to cease or be curtailed, and may include corrective measures requiring capital expenditures or remedial actions.

The acquisition of title to resource properties in this part of the western USA is a very detailed and time-consuming process. No assurances can be given that there are no title defects affecting the properties in which Integra has an interest, particularly on the DeLamar Project. The DeLamar Project includes areas with prospective exploration potential that lie on unpatented mining claims with a lengthy history of prior ownership and operations. The DeLamar Project may be subject to prior unregistered liens, agreements, transfers or claims, and title may be affected by, among other things, undetected defects. Other parties may dispute title to a property or the property may be subject to prior unregistered agreements and transfers or land claims by indigenous people. Title may also be affected by undetected encumbrances or defects or governmental actions. Integra has not conducted surveys of the DeLamar Project and the precise area and location of claims and other mineral rights may be challenged. Integra may not be able to register rights and interests it acquires against title to applicable mineral properties. An inability to register such rights and interests may limit or severely restrict Integra's ability to enforce such acquired rights and interests against third parties or may render certain agreements entered into by Integra invalid, unenforceable, uneconomic, unsatisfied or ambiguous, the effect of which may cause financial results yielded to differ materially from those anticipated. Although Integra believes it has taken reasonable measures to ensure proper title to the DeLamar Project, there is no guarantee that such title will not be challenged or impaired.

The DeLamar Project is also subject to annual compliance with assessment work and/or fee requirements, property taxes, lease payments and other contractual payments and obligations. Any failure to make such payments or comply with such requirements or obligations could result in the loss of all or a portion of the Company's interest in the DeLamar Project.

The mineral properties in which Integra holds an interest, or the exploration equipment and road or other means of access which Integra intends to utilize in carrying out its work programs or general business mandates, may be subject to interests or claims by third party individuals, groups or companies. In the event that such third parties assert any claims, Integra's work programs may be delayed even if such claims are not meritorious. Such claims may result in significant financial loss and loss of opportunity for Integra.

Exploration, development and production operations on mineral properties involve numerous risks, including unexpected or unusual geological operating conditions, ground or slope failures, fires, environmental occurrences and natural phenomena such as prolonged periods of inclement weather conditions, floods and earthquakes. It is not always possible to obtain insurance against all such risks and Integra may decide not to insure against certain risks because of high premiums or other reasons. Such occurrences could result in damage to, or destruction of, mineral properties or production facilities, personal injury or death, environmental damage to Integra's properties or the properties of others, delays in exploration, development or mining operations, monetary losses and possible legal liability. Integra expects to maintain insurance within ranges of coverage which it believes to be consistent with industry practice for companies of a similar stage of development. Integra expects to carry liability insurance with respect to its mineral exploration operations, but is not expected to cover any form of political risk insurance or certain forms of environmental liability insurance, since insurance against political risks and environmental risks (including liability for pollution) or other hazards resulting from exploration and development activities is prohibitively expensive. Should such liabilities arise, they could reduce or eliminate future profitability and result in increasing costs and a decline in the value of the securities of Integra. If Integra is unable to fully fund the cost of remedying an environmental problem, it might be required to suspend operations or enter into costly interim compliance measures pending completion of a permanent remedy. The lack of, or insufficiency of, insurance coverage could adversely affect Integra's future cash flow and overall profitability.

Significant and increasing competition exists for the limited number of mineral acquisition opportunities available. Integra expects to selectively seek strategic acquisitions in the future, however, there can be no assurance that suitable acquisition opportunities will be identified. As a result of this competition, some of which is with large established mining companies with substantial capabilities and greater financial and technical resources than Integra, Integra may be unable to acquire additional attractive mineral properties on terms it considers acceptable. In addition, Integra's ability to consummate and to integrate effectively any future acquisitions on terms that are favourable to Integra may be limited by the number of attractive acquisition targets, internal demands on resources, competition from other mining companies and, to the extent necessary, Integra's ability to obtain financing on satisfactory terms, if at all.

The Company's relationships with the community in which it operates are critical to ensure the future success of its existing operations and the construction and development of the DeLamar Project. While the Company is committed to operating in a socially responsible manner, there is no guarantee that its efforts will be successful, in which case interventions by third parties could have a material adverse effect on the Company's business, financial condition, results of operations, cash flows or prospects.

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 Integra including macroeconomic developments in North America and globally, and market perceptions of the attractiveness of particular industries or asset classes, can impact the price of Integra's Common Shares. 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 of Integra at any given time may not accurately reflect the long-term value of Integra.

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 Integra.

The Company's Growth, Future Profitability and Ability to Obtain Financing may be Impacted by Global Financial Conditions

In recent years, global financial markets have been characterized by extreme volatility impacting many industries, including the mining industry. Global financial conditions remain subject to sudden and rapid destabilizations in response to future economic shocks, as government authorities may have limited resources to respond to future crises. A sudden or prolonged slowdown in the financial markets or other economic conditions, including but not limited to, consumer spending, employment rates, business conditions, inflation, fuel and energy costs, consumer debt levels, lack of available credit, the state of the financial markets, interest rates and tax rates, may adversely affect the Company's growth and profitability. Future economic shocks may be precipitated by a number of causes, including, but not limited to, material changes in the price of oil and other commodities, the volatility of metal prices, governmental policies, geopolitical instability, war, terrorism, the devaluation and volatility of global stock markets, natural disasters and the current outbreak of COVID-19 and any future emergence and spread of pathogens. Any sudden or rapid destabilization of global economic conditions could impact the Company's ability to obtain equity or debt financing in the future on terms favorable to the Company or at all. In such an event, the Company's operations and financial condition could be materially adversely affected.

A Cyber Security Incident Could Adversely Affect the Company's Ability to Operate its Business

Information systems and other technologies, including those related to the Company's financial and operational management, and its technical and environmental data, are an integral part of the Company's business activities. Network and information systems related events, such as computer hacking, cyber-attacks, computer viruses, worms or other destructive or disruptive software, process breakdowns, denial of service attacks, or other malicious activities or any combination of the foregoing or power outages, natural disasters, terrorist attacks, or other similar events could result in damages to the Company's property, equipment and data. These events also could result in significant expenditures to repair or replace damaged property or information systems and/or to protect them from similar events in the future. Furthermore any security breaches such as misappropriation, misuse, leakage, falsification, accidental release or loss of information contained in the Company's information technology systems including personnel and other data that could damage its reputation and require the Company to expend significant capital and other resources to remedy any such security breach. Insurance held by the Company may mitigate losses however in any such events or security breaches may not be sufficient to cover any consequent losses or otherwise adequately compensate the Company for any disruptions to its business that may result and the occurrence of any such events or security breaches could have a material adverse effect on the business of the Company. There can be no assurance that these events and/or security breaches will not occur in the future or not have an adverse effect of the business of the Company.

Despite efforts to attract and retain qualified personnel, as well as the retention of qualified consultants, to manage Integra's interests, and even when those efforts are successful, people are fallible and human error could result in significant uninsured losses to Integra. These could include loss or forfeiture of mineral claims or other assets for non-payment of fees or taxes, significant tax liabilities in connection with any tax planning effort Integra might undertake and legal claims for errors or mistakes by Integra personnel.

Certain directors and officers of Integra are, and may continue to be, involved in the mining and mineral exploration industry through their direct and indirect participation in corporations, partnerships or joint ventures which are potential competitors of Integra. Situations may arise in connection with potential acquisitions in investments where the other interests of these directors and officers may conflict with the interests of Integra. Directors and officers of Integra with conflicts of interest will be subject to the procedures set out in applicable corporate and securities legislation, regulation, rules and policies.

Disclosure controls and procedures are designed to provide reasonable assurance that material information is gathered and reported to management, as appropriate to allow for timely decisions about public disclosure. The Company has disclosure controls and procedures in place to provide reasonable assurance that any information required to be disclosed by the Company under securities legislation is recorded, processed, summarized, and reported within the applicable time periods and that required information is accumulated and communicated to the Company's management, so that decisions can be made about the timely disclosure of that information.

Management has evaluated the effectiveness of the design and operation of the Company's disclosure controls as of December 31, 2021 and concluded that the disclosure controls and procedures were effective.

Management is responsible for establishing and maintaining adequate internal controls over financial reporting as such term is defined in the rules of the National Instrument 52-109 - Certification of Disclosure in Issuers' Annual and Interim Filings ("NI 52-109") and Rule 13a-15(f) of the Exchange Act. The Company's internal controls over financial reporting is designed to provide reasonable assurance regarding the reliability of the Company's financial reporting for external purposes in accordance with IFRS as issued by the IASB.

Based on the criteria set forth in Internal Control - Integrated Framework (2013) by the Committee of Sponsoring Organizations of the Treadway Commission, the Company's internal controls over financial reporting include:

Management has evaluated the effectiveness of the internal controls over financial reporting as of December 31, 2021 and concluded that those controls were effective.

An independent consultant was engaged to assist management in assessing the effectiveness of internal controls over financial reporting. The independent consultant reported his opinion to management and to the Audit Committee and concluded that the Company's internal controls are effective.

Though the Company believes its internal safeguards over financial reporting are effective, the Company cannot provide absolute assurance.

Management believes that any disclosure controls and procedures or internal control over financial reporting, no matter how well designed and operated, have their inherited limitations. Due to those limitations (resulting from unrealistic or unsuitable objectives, human judgment in decision making, human errors, management overriding internal control, circumventing controls by the individual acts of some persons, by collusion of two or more people, external events beyond the entity's control), internal control can only provide reasonable assurance that the objectives of the control system are met.

The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Due to the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

There were no changes in internal controls of the Company during the year-ended December 31, 2021 that have materially affected, or are likely to materially affect, the Company's internal control over financial reporting.

Risks Relating to the Company's Status as a "Foreign Private Issuer" Under U.S. Securities Laws

The Company is a "foreign private issuer", under applicable U.S. federal securities laws, and is, therefore, not subject to the same requirements that are imposed upon U.S. domestic issuers by the SEC. Under the United States Securities Exchange Act of 1934, as amended (the "Exchange Act'), the Company is subject to reporting obligations that, in certain respects, are less detailed and less frequent than those of U.S. domestic reporting companies. As a result, the Company does not file the same reports that a U.S. domestic issuer would file with the SEC, although the Company is required to file with or furnish to the SEC the continuous disclosure documents that it is required to file in Canada under Canadian securities laws. In addition, the Company's officers, directors, and principal shareholders are exempt from the reporting and short-swing profit recovery provisions of Section 16 of the Exchange Act. Therefore, the Company's shareholders may not know on as timely a basis when the Company's officers, directors and principal shareholders purchase or sell Common Shares, as the reporting periods under the corresponding Canadian insider reporting requirements are longer.

As a foreign private issuer, the Company is exempt from the rules and regulations under the Exchange Act related to the furnishing and content of proxy statements. The Company is also exempt from Regulation FD, which prohibits issuers from making selective disclosures of material non-public information. While the Company complies with the corresponding requirements relating to proxy statements and disclosure of material non-public information under Canadian securities laws, these requirements differ from those under the Exchange Act and Regulation FD and shareholders should not expect to receive the same information at the same time as such information is provided by U.S. domestic companies. In addition, the Company may not be required under the Exchange Act to file annual and quarterly reports with the SEC as promptly as U.S. domestic companies whose securities are registered under the Exchange Act.

In addition, as a foreign private issuer, the Company has the option to follow certain Canadian corporate governance practices, except to the extent that such laws would be contrary to U.S. securities laws, and provided that the Company disclose the requirements it is not following and describe the Canadian practices it follows instead. The Company may in the future elect to follow home country practices in Canada with regard to certain corporate governance matters. As a result, the Company's shareholders may not have the same protections afforded to shareholders of U.S. domestic companies that are subject to all corporate governance requirements.

The Company May Lose its Status as a Foreign Private Issuer Under U.S. Securities Laws

In order to maintain its status as a foreign private issuer, a majority of the Company's Common Shares must be either directly or indirectly owned by non-residents of the U.S. unless the Company also satisfies one of the additional requirements necessary to preserve this status. The Company may in the future lose its foreign private issuer status if a majority of its Common Shares are held in the U.S. and if the Company fails to meet the additional requirements necessary to avoid loss of its foreign private issuer status. The regulatory and compliance costs under U.S. federal securities laws as a U.S. domestic issuer may be significantly more than the costs incurred as a Canadian foreign private issuer eligible to use the multi-jurisdictional disclosure system ("MJDS"). If the Company is not a foreign private issuer, it would not be eligible to use the MJDS or other foreign issuer forms and would be required to file periodic and current reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. In addition, the Company may lose the ability to rely upon exemptions from NYSE American corporate governance requirements that are available to foreign private issuers.

Risks Relating to the Company's Status as an "Emerging Growth Company" Under U.S. Securities Laws

The Company is an "emerging growth company" as defined in section 3(a) of the Exchange Act (as amended by the JOBS Act, enacted on April 5, 2012), and the Company will continue to qualify as an emerging growth company until the earliest to occur of: (a) the last day of the fiscal year during which the Company has total annual gross revenues of $1,070,000,000 (as such amount is indexed for inflation every five years by the SEC) or more; (b) the last day of the fiscal year of the Company following the fifth anniversary of the date of the first sale of common equity securities of the Company pursuant to an effective registration statement under the United States Securities Act of 1933, as amended; (c) the date on which the Company has, during the previous three year period, issued more than $1,000,000,000 in non-convertible debt; and (d) the date on which the Company is deemed to be a "large accelerated filer", as defined in Rule 12b-2 under the Exchange Act. The Company will qualify as a large accelerated filer (and would cease to be an emerging growth company) at such time when on the last business day of its second fiscal quarter of such year the aggregate worldwide market value of its common equity held by non-affiliates will be $700,000,000 or more.

For so long as the Company remains an emerging growth company, it is permitted to and intends to rely upon exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include not being required to comply with the auditor attestation requirements of Section 404 of the JOBS Act. The Company takes advantage of some, but not all, of the available exemptions available to emerging growth companies. The Company cannot predict whether investors will find the Common Shares less attractive because the Company relies upon certain of these exemptions. If some investors find the Common Shares less attractive as a result, there may be a less active trading market for the Common Shares and the Common Share price may be more volatile. On the other hand, if the Company no longer qualifies as an emerging growth company, the Company would be required to divert additional management time and attention from the Company's development and other business activities and incur increased legal and financial costs to comply with the additional associated reporting requirements, which could negatively impact the Company's business, financial condition, results of operations, cash flows or prospects.

The bulk of the information in this section is derived from the "Technical Report and Preliminary Feasibility Study for the DeLamar and Florida Mountain Gold - Silver Project, Owyhee County, Idaho, USA", dated March 22, 2022 with an effective date of January 24, 2022 (the "DeLamar Report"), which was filed on March 28, 2022 with Canadian securities regulatory authorities and prepared pursuant to NI 43-101. The DeLamar Report was prepared under the supervision of Thomas L. Dyer, P.E. and Senior Engineer for MDA, Michael M. Gustin, C.P.G. and Senior Geologist for MDA, Steven I. Weiss, C.P.G. and Senior Associate Geologist for MDA, Jack McPartland, Registered Member MMSA and Senior Metallurgist with McClelland Laboratories, Inc., John Welsh, P.E., of Welsh Hagen in Reno, Nevada, Matthew Sletten, P.E. and Benjamin Bermudez, P.E. of M3 Engineering in Tucson, Arizona, Art Ibrado, P.E., of Fort Lowell Consulting in Tucson, Arizona, Jay Nopola, P.E, of RESPEC in Rapid City, South Dakota, Michael Botz, P.E., of Elbow Creek Engineering in Billings, Montana, and John F. Gardner, P.E. of Warm Springs Consulting in Boise, Idaho, in accordance with the disclosure and reporting requirements set forth in NI 43-101. Mr. Dyer, Mr. Gustin, Mr. Weiss, Mr. McPartland, Mr. Welsh, Mr. Sletten, Mr. Bermudez, Mr. Ibrado, Mr. Botz, Mr. Nopola, and Mr. Gardner are QPs under NI 43-101 and have no affiliation with Integra, their subsidiaries, or Kinross except that of independent consultant/client relationships.

The DeLamar Project includes of 790 unpatented lode, placer, and millsite claims, and 16 tax parcels comprised of patented mining claims, as well as certain leasehold and easement interests, that cover approximately 8,673 hectares (21,431 acres) in southwestern Idaho, about 80km (50 miles) southwest of Boise. The property is approximately centered at 43°00′48″N, 116°47′35″W, within portions of the historical Carson (Silver City) mining district, and it includes the formerly producing DeLamar mine last operated by Kinross Gold Corporation ("Kinross"). The total annual land-holding costs are estimated to be $473,244. All mineral titles and permits are held by DMC, an indirect, 100% wholly owned subsidiary of Integra that was acquired from Kinross through the DeLamar Purchase Agreement in 2017.

Of the 284 unpatented claims acquired from Kinross, 101 are subject to a 2.0% NSR royalty payable to a predecessor owner. This royalty is not applicable to the current project Mineral Resources and Reserves. There are also eight lease agreements covering 33 patented claims and five unpatented claims that require NSR payments ranging from 2.0% to 5.0%. One of these leases covers a small portion of the DeLamar Area Mineral Resources and one covers a small portion of the Florida Mountain Area Mineral Resources and Reserves, with 5.0% and 2.5% NSRs applicable to maximums of $50,000 and $650,000 in royalty payments, respectively. The DeLamar Project includes 1,561 hectares (3,857.2 acres) under seven leases from the State of Idaho, which are subject to a 5.0% NSR production royalty plus annual payments of $27,282. The State of Idaho leases include very small portions of both the DeLamar and Florida Mountain Area Mineral Resources and Reserves.

Kinross has retained a 2.5% NSR royalty (i.e. the "Kinross Royalty") that applies to those portions of the DeLamar Area claims that are unencumbered by the royalties outlined above. The Kinross Royalty applies to more than 90% of the current DeLamar Area Mineral Resources, but this royalty will be reduced to 1.0% upon Kinross receiving total royalty payments of C$10,000,000. The Kinross Royalty was subsequently purchased by Maverix on December 19, 2019. DMC also owns mining claims and leased lands peripheral to the DeLamar Project described above. These landholdings are not part of the DeLamar Project, although some of the lands are contiguous with those of the DeLamar and Florida Mountain claims and State Leases. The DMC lands peripheral to the DeLamar Project have no Mineral Resources or Reserves.

The principal access to the DeLamar Project is from U.S. Highway 95 and the town of Jordan Valley, Oregon, proceeding east on Yturri Blvd. from Jordan Valley for 7.6km (4.7 miles) to the Trout Creek Road. It is then another 39.4km (24.5 miles) travelling east on the gravel Trout Creek Road to reach the DeLamar mine tailing facility and nearby site office building. Travel time by automobile via this route is approximately 35 minutes. Secondary access is from the town of Murphy, Idaho and State Highway 78, via the Old Stage Road and the Silver City Road. Travel time by this secondary route is estimated to be about 1.5 hours.

The 1977 - 1998 DeLamar open-pit mining operations included the DeLamar and Florida Mountain Areas. The DeLamar Area mine facilities, specifically the historical Sommercamp and North DeLamar open pits, incorporate essentially all the historical underground mining features (adits and dumps) in the vicinity. In the Florida Mountain Area, many historical underground mining features remain to the north of the historical Florida Mountain Area open pits and waste rock dump, and several of these historical underground mining features are located within the DeLamar Project, including collapsed adits, dumps, and collapsed structures. None of these features have water discharging to the environment

The DeLamar Project historical open-pit mine areas have been in closure since 2003. While a substantial amount of reclamation and closure work has been completed to date at the site, there remain ongoing water-management activities, monitoring, and reporting. A reclamation bond of $2,778,929 remains with the IDL and a reclamation bond of $100,000 remains with the IDEQ. Additional reclamation bonds in the total amount of $589,144 have been placed with the BLM for exploration activities and groundwater well installation on public lands. There are also reclamation bonds with the IDL in the total amount of $86,900 for exploration activities on IDL leased lands.

The DeLamar Project holds the following primary permits: two Plans of Operation ("PoO"), one with IDL and the BLM (PoO #248), and one with IDL (PoO #936). In addition, DMC holds a Cyanidation Permit from the IDEQ, an Air Quality Permit from IDEQ, a Dam Safety Permit from the IDWR, and a 2015 Multi-Sector General Permit, Storm Water Permit, and a Ground Water Remediation Permit from the United States Environmental Protection Agency.

As of the date of the DeLamar Report, Integra is conducting a drilling program on patented and unpatented mining claims in the DeLamar and Florida Mountain Areas. This drilling is being undertaken under a notification from IDL, as well as two notices filed with the BLM. The exploration program recommended in the DeLamar Report includes proposed drilling in the Florida Mountain Area, as well as further drilling in the DeLamar Area. This proposed work would necessitate a modification to the existing notification for drilling in the DeLamar Area, and a new notification for Florida Mountain Area drilling performed on patented claims. A notice would need to be filed with the BLM if any of the recommended drilling is undertaken on unpatented claims. Separate notices would be filed with the BLM for each of the DeLamar and Florida Mountain Areas of unpatented claims.

Please refer to "General Development of the Business - Three Year History" section above for further details on recent environmental and permitting work performed by Integra.

Total production of gold and silver from the DeLamar Project area is estimated to be approximately 1.3 million ounces of gold and 70 million ounces of silver from 1891 through 1998, with an additional but unknown quantity produced at the DeLamar mill in 1999. From 1876 to 1891, an estimated 1.025 million ounces of gold and 51 million ounces of silver were produced from the original De Lamar underground mine and the later DeLamar open-pit operations. At the Florida Mountain Area, nearly 260,000 ounces of gold and 18 million ounces of silver were produced from the historical underground mines and late 1990s open-pit mining.

Mining activity began in the area of the DeLamar Project when placer gold deposits were discovered in early 1863 in Jordan Creek, a short distance upstream from what later became the town site of De Lamar. During the summer of 1863, the first silver-gold lodes were discovered in quartz veins at War Eagle Mountain, to the east of the Florida Mountain Area, resulting in the initial settlement of Silver City. Between 1876 and 1888, significant silver-gold veins were discovered and developed in the district, including underground mines at De Lamar Mountain and the Florida Mountain Area. A total of 553,000 ounces of gold and 21.3 million ounces of silver were reportedly produced from the De Lamar and Florida Mountain Area underground mines from the late 1800s to early 1900s.

The mines in the district were closed in 1914, following which very little production took place until gold and silver prices increased in the 1930s. Placer gold was again recovered from Jordan Creek from 1934 to 1940, and in 1938 a 181 tpd flotation mill was constructed to process waste dumps from the De Lamar underground mine. The flotation mill reportedly operated until the end of 1942. Including the Florida Mountain Area, the De Lamar - Silver City area is believed to have produced about 1 million ounces of gold and 25 million ounces of silver from 1863 through 1942.

During the late 1960s, the district began to undergo exploration for near-surface bulk-mineable gold-silver deposits, and in 1977 a joint venture operated by Earth Resources Corporation ("Earth Resources") began production from an open-pit, milling and cyanide tank-leach operation at De Lamar Mountain, known as the DeLamar mine. In 1981, Earth Resources was acquired by the Mid Atlantic Petroleum Company ("MAPCO"), and in 1984 and 1985 the NERCO Mineral Company ("NERCO") successively acquired the MAPCO interest and the entire joint venture to operate the DeLamar mine with 100% ownership. NERCO was purchased by the Kennecott Copper Corporation ("Kennecott") in 1993. Two months later in 1993, Kennecott sold its 100% interest in the DeLamar mine and property to Kinross, and Kinross operated the mine, which expanded to the Florida Mountain Area in 1994. Mining ceased in 1998, milling ceased in 1999, and mine closure activities commenced in 2003. Closure and reclamation were nearly completed by 2014, as the mill and other mine buildings were removed, and drainage and cover of the tailing facility were developed.

Total open-pit production from the DeLamar Project from 1977 through 1998, including the Florida Mountain Area operation, is estimated at approximately 750,000 ounces of gold and 47.6 million ounces of silver, with an unknown quantity produced at the DeLamar mill in 1999. From start-up in 1977 through to the end of 1998, open-pit production in the DeLamar Area totaled 625,000 ounces of gold and about 45 million ounces of silver. This production came from pits developed at the Glen Silver, Sommercamp - Regan (including North and South Wahl), and North DeLamar areas. In 1993, the DeLamar mine was operating at a mining rate of 27,216 tonnes (30,000 tons) per day, with a milling capacity of about 3,629 tonnes (4,000 tons) per day. In 1994, Kinross commenced open-pit mining at the Florida Mountain Area while continuing production from the DeLamar mine. The ore from the Florida Mountain Area, which was mined through 1998, was processed at the DeLamar facilities. Florida Mountain Area production in 1994 through 1998 totaled 124,500 ounces of gold and 2.6 million ounces of silver.

The estimates described in here are presented herein as an item of historical interest with respect to historical open-pit mining and exploration at the DeLamar Project property. The historical estimations presented below are considered relevant because they represent an "ore reserve" that formed the basis of the initial open-pit mining, "reserves" estimated at the time of Kinross' acquisition of the mining operations, and "resources" estimated at the time of closure of the open-pit mining operations. The classification terminology is presented as described in the original references, but these categories do not conform to the Measured, Indicated, and Inferred Mineral Resource classifications as set out in NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the CIM Definition Standards). There is insufficient information for the relevant author of the DeLamar Report to understand how these historical categories differ from CIM Definition Standards. In addition, the relevant author of the DeLamar Report has not completed sufficient work to classify these historical estimates as current Mineral Resources or Reserves, and Integra is not treating these historical estimates as current Mineral Resources or Reserves. The relevant author of the DeLamar Report is unaware of the key assumptions, parameters, and methods used to prepare the historical estimates. The historical estimates have been superseded by the current Mineral Resource and Reserve estimates described in the DeLamar Report and therefore they cannot be upgraded or verified as current Mineral Resources or Reserves. Accordingly, these estimates are relevant only for historical context and should not be relied upon.

The first reported historical "ore reserve" was presented in a 1974 feasibility study prepared by the Exploration Division of Earth Resources. A total of 4.124 million tonnes of "ore reserves" with average grades of 142.29 grams Ag/t and 1.58 grams Au/t, for about 18.8 million silver ounces and 210,000 gold ounces, were estimated for the Sommercamp and North DeLamar zones.

At the time of the Kinross acquisition of the DeLamar operations and properties in 1993, the end-of-year 1992 reserves for the DeLamar mine area were estimated by Elkin (1993) at approximately 9.335 million tonnes with average silver and gold grades of 55.86 grams Ag/t and 0.72 grams Au/t, respectively. Following the cessation of mining at the end of 1998 due to low metal prices, Kinross reported estimated resources and no reserves of 8.406 million tonnes with average silver and gold grades of 32.05 grams Ag/t and 1.25 grams Au/t, respectively.

In October 2017 Integra produced an initial Mineral Resource estimate on the DeLamar Project. The Company subsequently updated the Mineral Resource estimate in March 2018. In June 2019, Integra completed the 2019 Technical Report, including an updated Mineral Resource estimate for the DeLamar Project, which includes the DeLamar and Florida Mountain Area deposits. The 2019 PEA was based on the updated Mineral Resource estimate in the 2019 Technical Report. In March 2022, the Company filed the DeLamar Report including an updated Mineral Resource estimate and an initial Mineral Reserve estimate. The Mineral Resource and Reserve estimates are provided under the heading "Mineral Resources and Reserves" below and the PFS included in the DeLamar Report is based on the Mineral Reserve estimate.

The DeLamar Project is situated in the Owyhee Mountains near the east margin of the mid-Miocene Columbia River - Steens flood-basalt province and the west margin of the Snake River Plain. The Owyhee Mountains comprise a major mid-Miocene eruptive center, generally composed of mid-Miocene basalt flows intruded and overlain by mid-Miocene rhyolite dikes, domes, flows and tuffs, developed on an eroded surface of Late Cretaceous granitic rocks.

The DeLamar mine area and mineralized zones are situated within an arcuate, nearly circular array of overlapping porphyritic and flow-banded rhyolite flows and domes that overlie cogenetic, precursor pyroclastic deposits erupted as local tuff rings. Integra interprets the porphyritic and banded rhyolite flows and latites as composite flow domes and dikes emplaced along regional-scale northwest-trending structures. At the Florida Mountain Area, flow-banded rhyolite flows and domes cut through and overlie a tuff breccia unit that overlies basaltic lava flows and Late Cretaceous granitic rocks.

Gold-silver mineralization occurred as two distinct but related types: (i) relatively continuous, quartz-filled fissure veins that were the focus of late 19th and early 20th century underground mining, hosted mainly in the basalt and granodiorite and to a lesser degree in the overlying felsic volcanic units; and (ii) broader, bulk-mineable zones of closely-spaced quartz veinlets and quartz-cemented hydrothermal breccia veins that are individually continuous for only a few meters/feet laterally and vertically, and of mainly less than 1.3cm (0.5 inches) in width - predominantly hosted in the rhyolites and latites peripheral to and above the quartz-filled fissures. This second style of mineralization was mined in the open pits of the late 20th century DeLamar and Florida Mountain Area operations, hosted primarily by the felsic volcanic units.

The fissure veins mainly strike north to northwest and are filled with quartz accompanied by variable amounts of adularia, sericite or clay, ± minor calcite. Vein widths vary from a few centimeters to several meters, but the veins persist laterally and vertically for as much as several hundreds of meters. Principal silver and gold minerals are naumannite, aguilarite, argentite, ruby silver, native gold and electrum, native silver, cerargyrite, and acanthite. Variable amounts of pyrite and marcasite with very minor chalcopyrite, sphalerite, and galena occur in some veins. Gold- and silver-bearing minerals are generally very fine grained.

Based upon the styles of alteration, the nature of the veins, the alteration and vein mineralogy, and the geologic setting, the gold and silver mineralization at the DeLamar Project is best interpreted in the context of the volcanic-hosted, low-sulfidation type of epithermal model. This model has its origins in the De Lamar - Silver City district, where it was first developed by Lindgren (1900) based on his first-hand studies of the veins and altered wallrocks in the De Lamar and Florida Mountain mines. Various vein textures, mineralization, and alteration features, and the low contents of base metals in the district are typical of what are now known as low-sulfidation epithermal deposits world-wide. The host-rock setting of mineralization at the DeLamar Project is similar to the simple model shown in the figure below, with the lower basalt sequence occupying the stratigraphic position of the volcano-sedimentary rocks shown below. The Milestone portion of the district appears to be situated within and near the surficial sinter terrace in this model.

Many other deposits of this class occur within the Basin and Range province of Nevada, and elsewhere in the world. Some well-known low-sulfidation epithermal gold and silver properties with geological similarities to the DeLamar Project include the past-producing Rawhide, Sleeper, Midas, and Hog Ranch mines in Nevada. The Midas district includes selenium-rich veins similar to, but much richer in calcite, than the veins known in the DeLamar Project. At both the DeLamar Project and Midas, epithermal mineralization took place coeval with rhyolite volcanism, and shortly after basaltic volcanism, during middle Miocene time.

Exploration work other than drilling has included topographic and geophysical surveys, airborne magnetic surveys, IP/Resistivity surveys, rock and soil geochemical sampling, geologic mapping, database development and checking and cross-sectional geologic modelling. The results of this work and interpretations were applied to the estimation of Mineral Resources in the DeLamar Report.

Please refer to "General Development of the Business - Three Year History" section above for further details on recent exploration work performed by Integra.

As of the effective date of the DeLamar Report, the Mineral Resource database includes data from 2,836 holes, for a total of 337,268m (1,106,522 feet), that were drilled by Integra and various historical operators at the DeLamar and Florida Mountain Areas.

The historical drilling was completed from 1966 to 1998 and includes 2,625 holes for a total of 275,790m (904,821 feet) of drilling. Most of the historical drilling was done using RC and conventional rotary methods; a total of 106 historical holes were drilled using diamond-core ("core") methods for a total of 10,845m (35,581 feet). Approximately 74% of the historical drilling was vertical, including all historical conventional rotary holes. At DeLamar, a significant portion of the total meterage drilled historically was subsequently mined during the open-pit operations.

Integra commenced drilling in 2018. As of the end of December 2020, Integra had drilled a total of 60 RC holes, 140 core holes, and 11 holes commenced with RC and finished with core tails, for a total of 61,478 meters (201,699 feet) in the DeLamar and Florida Mountain Areas combined. All but one of the Integra holes were angled. Integra's drilling continued through 2021 but none of the 2021 drilling is included in the Mineral Resource database used to estimate the current Mineral Resources included in the DeLamar Report.

Integra commenced drilling in February 2018. Please refer to "General Development of the Business - Three Year History" section above for further details on recent drilling.

Of the historical holes for which the drilling method is known, 602 of the DeLamar Area holes were drilled by RC, 438 by conventional rotary, and 60 were core holes. 74% of the historical holes in the DeLamar Area were vertical. At the Florida Mountain Area, 961 of the historical holes were drilled by RC methods, 58 by conventional-rotary methods, and 46 by diamond core methods; less than 10% of the historical holes were vertical. None of the conventional rotary holes were angled in either area. A combined total of 106 holes were drilled using core methods for a total of 10,822m (35,505 feet), or 3.9% of the overall meterage drilled. The median down-hole depth of all historical holes in the DeLamar Area is 91m (298.6 feet), and the median depth in the Florida Mountain Area is 123m (403.5 feet).

Down-hole contamination is always a concern with holes drilled by rotary (RC or conventional) methods. Contamination occurs when material originating from the walls of the drill hole above the bottom of the hole is incorporated with the sample being extracted at the bit face at the bottom of the hole. The potential for down-hole contamination increases substantially if significant water is present during drilling, whether the water is from in-the-ground sources or injected by the drillers. Conventional rotary holes, in which the sample is returned to the surface along the space between the drill rods and the walls of the drilled hole, are particularly susceptible to down-hole contamination, although these concerns are limited at the DeLamar project due to the shallow depths and vertical orientation of the rotary holes, and the fact that a significant quantity of the rotary data was mined out during the historical mining operations.

Some of the drill-hole logs reviewed by MDA were found to have notations as to the presence of water during drilling, as well as occasional comments concerning drilling difficulties and sample sizes. Integra therefore comprehensively compiled sample quality information from the historical drill logs, and this information, which includes logged notes on intersected groundwater and/or drill-injected fluids, was used by MDA in the modeling of DeLamar Project Mineral Resources.

There is a complete lack of down-hole deviation survey data for the historical holes in the DeLamar Area database, and the Florida Mountain Area database includes deviation data for 33 RC and four core holes. While the paucity of such data is not unusual for drilling done prior to the 1990s, the lack of deviation data contributes a level of uncertainty as to the exact locations of drill samples at depth. However, in the DeLamar Area these uncertainties are mitigated to a significant extent by the vertical orientation of three-quarters of the drill holes, the generally shallow down-hole depths, and the likely open-pit nature of any potential future mining operation that is based in part on data derived from the historical holes. Such uncertainties, while still minor, are more pronounced in the Florida Mountain Area, where about 80% of the historical holes were inclined, and the holes were generally slightly longer than those in the DeLamar Area. In consideration of the fact that any potential future mining operation that would rely in part on the reliability of the historical drill data would entail open-pit methods, the potential inaccuracies in the locations of drill samples imparted by the lack of down-hole surveys is not considered to be a material issue.

Down-hole lengths of gold and silver intercepts derived from vertical holes, which were almost exclusively historical holes, can significantly exaggerate true mineralized thicknesses in cases where steeply dipping holes intersect steeply dipping mineralization, for example in portions of the Sommercamp area. This effect is entirely mitigated by the modeling techniques employed in the estimation of the current Mineral Resources, however, which constrain all intercepts to lie within explicitly interpreted domains that appropriately respect the known and inferred geologic controls and mineralized thicknesses.

The overwhelming majority of sample intervals in the DeLamar and Florida Mountain Area databases have a down-hole length of 1.52m (5.0 feet). This sample length is considered appropriate for the near-surface style of mineralization that characterizes the current Mineral Resources at both the DeLamar and Florida Mountain Areas.

Beyond the sample-quality noted above, which were identified and the affected samples removed from use in the estimation of the DeLamar Project Mineral Resources, the relevant author of the DeLamar Report is unaware of any sampling or sample-recovery factors that materially impact the accuracy and reliability of the drill-hole data, and believes that the drill samples are of sufficient quality for the purposes used in the DeLamar Report.

The relevant authors of the DeLamar Report are not aware of sample-preparation procedures or sample-security protocols employed prior to the start-up of open-pit mining operations in 1977, although further detailed reviews of historical documentation may yield such information in the future.

According to one historical report from 1993, sample preparation procedures at the mine laboratory had remained relatively constant up to the date of such ore-reserve report. Drill cuttings were split at the drill site to obtain samples weighing approximately 4.5kg (10 pounds). When received at the mine laboratory, the samples were dried and crushed to -10 mesh. Splits of 150mm (9.15 cubic inch) volumes were then pulverized to pulps with 90% passing 100 mesh. At the date of the report, one-assay-ton (30-gram) (1.06-ounce) aliquots were taken from these pulps for assaying.

The relevant authors of the DeLamar Report are unaware of any specific sample-security protocols undertaken during the various historical drilling programs at the DeLamar Project. However, approximately 75% of the drill data in the DeLamar Area database and 98% of the holes in the Florida Mountain Area are derived from drilling undertaken after the open-pit mining operations had initiated. It is very likely that the drilling and sampling completed during the mining operations were undertaken in areas of controlled access.

Until 1988, in-house assays were done by MIBK AA methods. From approximately 1988 through to the end of the open-pit mining operations, all analyses by the mine laboratory were completed using standard fire-assay methods.

Integra's RC and core samples were transported by the drilling contractor or Integra personnel from the drill sites to Integra's logging and core cutting facility at the DeLamar mine on a daily basis. The RC samples were allowed to dry for a few days at the drill sites prior to delivery to the secured logging and core-cutting facility.

The 2018, 2019 and 2020 core sample intervals were sawn lengthwise mainly into halves after logging and photography by Integra geologists and technicians in the logging and sample storage area. In some cases, the core was sawed into quarters. Sample intervals of either ½ or ¼ core were placed in numbered sample bags and the remainder of the core was returned to the core box and stored in a secure area on site. Core sample bags were closed and placed in a secure holding area awaiting dispatch to the analytical laboratory.

All of Integra's rock, soil and drilling samples were prepared and analyzed at American Assay Laboratories ("AAL") in Sparks, Nevada. AAL is an independent commercial laboratory accredited effective December 1, 2020 to the ISO/IEC Standard 17025:2017 for testing and calibration laboratories. The drilling samples were transported from the DeLamar mine logging and sample storage area to AAL by Integra's third-party trucking contractor.

The soil samples were screened to -80 mesh for multi-element analysis at AAL. MDA has no other information on the methods and procedures used for the preparation of Integra's soil and rock samples.

The same principal analytical methods were used at AAL for both soil and surface-rock samples collected by Integra. Gold was determined by fire-assay fusion of 60-gram (2.12-ounce) aliquots with an inductively coupled plasma optical-emission spectrometry ("ICP") finish. Silver and 44 major, minor and trace elements were determined by ICP and mass spectrometry ("ICP-MS") following a 5-acid digestion of 0.5-gram (0.018-ounce) aliquots. Rock samples that assayed greater than 10 g Au/t were re-analyzed by fire-assay fusion of 30-gram (1.06-ounce) aliquots with a gravimetric finish. Samples with greater than 100 g Ag/t were also re-analyzed fire-assay fusion of 30-gram aliquots with a gravimetric finish. Some rock samples were analyzed for gold using a metallic-screen fire assay procedure.

RC samples from the 2018 and 2019 drilling were dried upon arrival at AAL's Reno facility. The dry samples were crushed to a size of -6 mesh and then roll-crushed to -10 mesh. One-kilogram (2.205-pound) splits of the -10-mesh materials were pulverized to 95% passing -150 mesh. Sixty-gram aliquots of the one-kilogram pulps were analyzed at AAL for gold mainly by fire-assay fusion with an ICP finish. Silver and 44 major, minor, and trace elements were determined by ICP and ICP-MS following a 5-acid digestion of 0.5-gram aliquots. Samples that assayed greater than 10 g Au/t were re-analyzed by fire-assay fusion of 30-gram aliquots with a gravimetric finish. Samples with greater than 100 g Ag/t were also re-analyzed fire-assay fusion of 30-gram aliquots with a gravimetric finish. Selected RC samples were analyzed for gold using a metallic-screen fire assay procedure.

Integra's 2018, 2019 and 2020 core samples were prepared and assayed at AAL for gold, silver, and multi-elements using the identical methods used for Integra's RC samples.

Coarse blank material, certified reference materials ("CRMs"), and RC field duplicates were inserted into the drill-sample streams as part of Integra's quality assurance/ quality control procedures. The blank material consisted of coarse fragments of basalt that was inserted approximately every 10^th sample. Commercial CRMs were inserted as pulps at a frequency of approximately every 10^th sample.

Integra's sample preparation and analyses were performed at a well-known certified laboratory, and the sample security and assurance/quality control procedures were judged to be adequate by the relevant authors of the DeLamar Report.

The historical portions of the current resource drill-hole databases for the DeLamar and Florida Mountain Areas were created by MDA using original DeLamar mine digital database files, and this information was subjected to extensive verification measures by both MDA and Integra. The Integra portions of the drill-hole databases were directly created by MDA using original digital analytical certificates in the case of the assay tables and checking against original digital records in the case of the collar and down-hole deviation tables. Through these and numerous other verification procedures summarized in the DeLamar Report, the relevant author of the DeLamar Report has verified that the DeLamar Project data as a whole are acceptable as used in the DeLamar Report.

See "General Development of the Business - Three Year History" above for sampling and QA/QC procedure on recent drilling performed by Integra.

Useful information with respect to mineral processing of DeLamar Area gold-silver mineralization by milling and subsequent cyanide leaching is derived from mill production records from the historical open-pit mining operations from 1977 through to the end of 1992. All ore during this time period was mined from the DeLamar Area and was processed by crushing, grinding, and cyanide leaching, followed by precipitation with zinc dust and in-house smelting of the precipitate to produce silver-gold doré. After leaching, the solids were concentrated in a series of five thickening tanks and then pumped to a tailing impoundment. During mine closure the tailing were partially dewatered and capped with layers of clay and soil as part of the mine reclamation program.

The DeLamar Area produced 421,300 ounces of gold and about 26 million ounces of silver from 1977 through 1992 from 11.686 million tonnes of ore processed with average mill head grades of 1.17 grams Au/t and 87.1 grams Ag/t. The data relied upon indicated mill recoveries during the first 15 years of mine operation averaged 96.2% for gold and 79.5% for silver. It should be noted that Elkin (1993) surmised that, "Based on historical records and laboratory testing, the metallurgical recovery of gold is projected to be about 94 percent and 77 percent for silver."

Metallurgical testing by Integra, generally conducted at McClelland Laboratories during 2018 through 2021, has been used to select preferred processing methods and estimate recoveries for oxide, mixed and non-oxide mineralization from both the DeLamar and Florida Mountain Area. Samples used for this testing, primarily drill hole composites from 2018 through 2020 Integra drilling, were selected to represent the various material types contained in the current Mineral Resources from both the DeLamar and Florida Mountain Area. Composites were selected to evaluate effects of area, depth, grade, oxidation, lithology, and alteration on metallurgical response.

Bottle-roll and column-leach cyanidation testing on drill core composites from both the DeLamar and Florida Mountain Area and on bulk samples from the DeLamar Area have shown that the oxide and mixed material types from both deposits can be processed by heap-leach cyanidation. These materials generally benefit from relatively fine crushing to maximize heap-leach recoveries and a feed size of 80% -12.7mm (0.5 inches) was selected as optimum. Expected heap-leach gold recoveries for the oxide mineralization from both deposits (DeLamar and Florida Mountain Area) are consistently high (70% - 89%). Heap leach gold recoveries for the mixed mineralization are expected to average 72% for the Florida Mountain Area and to range from 45% to 63% for the DeLamar Area. Heap leach silver recoveries from the Florida Mountain Area oxide and mixed materials are expected to average 49% and 47%, respectively. Expected heap-leach silver recoveries from the DeLamar Area material are highly variable (11% to 74%), but generally low. A significant portion of the DeLamar Area oxide and mixed mineralization will require agglomeration pretreatment using cement, because of elevated clay content. None of the Florida Mountain Area heap-leach material is expected to require agglomeration.

Metallurgical testing (primarily flotation and agitated cyanidation) has shown that the DeLamar Area non-oxide materials respond well to flotation at a moderate grind size (150 microns) for recovery of gold and silver to a flotation concentrate. The resulting flotation concentrate responds well to cyanide leaching after very fine regrinding (20 microns) for recovery of contained silver. Some gold is also recovered by cyanide leaching of the reground flotation concentrate, but those recoveries generally are low. Mineralogical examination and metallurgical testing have shown that these materials contain significant amounts of gold that are locked in sulfide mineral particles, which require oxidative pretreatment of sulfide minerals (such as the Albion process) for liberation of gold before high cyanidation gold recoveries can be obtained. Expected recoveries from the DeLamar Area non-oxide mineralization in the planned mill circuit, consisting of grinding, flotation concentrate regrinding and cyanide leach, range from 28% to 39% for gold and from 64% to 87% for silver.

Metallurgical testing has shown that the non-oxide mineralization from the Florida Mountain Area responds well to upgrading by flotation at a moderate grind size (150 microns) and cyanidation gold and silver recoveries from the resulting concentrates can be maximized by very fine regrinding (20 microns). In contrast to the DeLamar Area non-oxide materials, oxidative pretreatment of contained sulfide minerals is not required to achieve high cyanidation gold recoveries from the Florida Mountain Area non-oxide feeds. Recoveries expected from the Florida Mountain Area non-oxide mineralization in the planned mill circuit vary with feed grade, but generally are high, with maximum recoveries of 87% gold and 77% silver.

The relevant author of the DeLamar Report has reviewed the historical metallurgical studies and the metallurgical studies conducted during 2018 through 2021 and concluded that the samples used during the 2018 through 2021 metallurgical studies are reasonably representative considering both the stage of the DeLamar Project development and the magnitude of the testing completed as of the effective date of the DeLamar Report. However, further testwork of samples collected from portions of the deposit, particularly those displaying high degrees of variability in metallurgical response, will be needed as the DeLamar Project advances. Other than as discussed herein and in the DeLamar Report, the relevant author of the DeLamar Report is not aware of any processing factors or deleterious elements that could have a significant effect on the potential economic extraction.

Mineral Resources have been estimated for both the Florida Mountain and DeLamar Areas of the DeLamar Project. These gold and silver resources were modeled and estimated by:

To meet the requirement of the in-pit resources having reasonable prospects for eventual economic extraction, pit optimizations for the DeLamar and Florida Mountain Areas were run using the parameters summarized in the below tables:

The DeLamar Project Mineral Resources were estimated to reflect potential open-pit extraction and processing by: crushing and heap leaching of oxide and mixed materials at both the DeLamar and Florida Mountain Areas; grinding, flotation, ultra-fine regrind of concentrates, and Albion cyanide-leach processing of the reground concentrates for the non-oxide materials at the DeLamar Area; and grinding, flotation, ultra-fine regrind of concentrates, and agitated cyanide-leaching of non-oxide materials at the Florida Mountain Area. To meet the requirement of having reasonable prospects for eventual economic extraction by open-pit methods, pit optimizations for the DeLamar and Florida Mountain Areas were run using the parameters summarized in the tables above, and the resulting pits were used to constrain the DeLamar Project Mineral Resources.

The pit shells created using these optimization parameters were applied to constrain the DeLamar Project Mineral Resources. The in-pit Mineral Resources were further constrained by the application of a gold-equivalent cutoff of 0.17 g/t to all model blocks lying within the optimized pits that are coded as oxide or mixed, a 0.3 g/t gold-equivalent cutoff for blocks coded as non-oxide at the DeLamar Area, and a 0.2 g/t cutoff for blocks coded as non-oxide at the Florida Mountain Area. Gold-equivalent grades, which were used solely for the purpose of applying the Mineral Resource cutoffs, are a function of metal prices and metal recoveries, with the recoveries varying by deposit and oxidation state (see above tables).

The total DeLamar Project Mineral Resources, including both the DeLamar and Florida Mountain Areas, are summarized in the below table. The DeLamar Project Mineral Resources are inclusive of the Mineral Reserves discussed herein. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

(3) Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

(4) Rounding may result in slight discrepancies between tonnes, grade, and contained metal content.

(5) The estimate of Mineral Resources may be materially affected by geology, environment, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

The gold and silver resources for the DeLamar and Florida Mountain Areas are reported separately in the table below.

(5) The estimate of Mineral Resources may be materially affected by geology, environment, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

Mineral Resources have been estimated for both the Florida Mountain and DeLamar Areas of the DeLamar Project. The relevant author of the DeLamar Report has used Measured and Indicated Mineral Resources as the basis to define Mineral Reserves for both the DeLamar and Florida Mountain Areas. Mineral Reserve definition was done by first identifying ultimate pit limits using economic parameters and pit optimization techniques. The resulting optimized pit shells were then used for guidance in pit design to allow access for equipment and personnel. The relevant author of the DeLamar Report then considered mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social, and governmental factors for defining the estimated Mineral Reserves.

The economic parameters and cutoff grades used in the estimation of the Mineral Reserves are shown in the table below. The overall leaching process rate is planned to be 35,000 tpd (38,581 tons) or 12,600,000 tonnes (13,889,123 tons) per year for both Florida Mountain and DeLamar Area oxide and mixed material. DeLamar Area leach processing will also include agglomeration. Initially only the oxide and mixed material will be processed, then starting in year 3, non-oxide will be processed through a plant constructed to operate at a rate of 6,000 tpd (6,614 tons) or 2,160,000 tonnes (2,380,992 tons) per year.

The cutoff grades applied reflect the cost to process material along with G&A and incremental haulage costs. Note that royalties are built into the block values and are considered in determining whether to process the material. While the DeLamar Area non-oxide breakeven cutoff grade would be $11.44/t according to the applicable costs, a cutoff of $15.00 was assigned to enhance the project's economic performance.

Total Proven and Probable Mineral Reserves for the DeLamar Project from all pit phases are 123,483,000 tonnes at an average grade of 0.45 g Au/t and 23.27 g Ag/t, for 1,787,000 ounces of gold and 92,403,000 ounces of silver. The Mineral Reserves point of reference is the point where material is fed into the crusher.

The PFS presented in the DeLamar Report considers open-pit mining of the DeLamar and Florida Mountain Areas. Mining will utilize 23-cubic meter (30-cubic yard) hydraulic shovels along with 13-cubic meter (16.7-cubic yard) loaders to load 136-tonne capacity haul trucks. The haul trucks will haul waste and ore out of the pit and to dumping locations. Due to the length of ore hauls, the ore will be stockpiled near the pits followed by loading into a Railveyor system which will convey the ore into a crusher. The Railveyor system will be supplemented with haul trucks on an as needed basis.

Waste material will be stored in waste-rock storage facilities ("WRSFs") located near each of the Florida Mountain and DeLamar Areas, as well as backfilled into pits where available. The exception is the Milestone pit, from which waste material will be fully utilized for construction material for the tailing storage facility ("TSF").

Production scheduling was completed using Geovia's MineSched™ (version 2021) software. Proven and Probable Mineral Reserves along with waste material inside pit designs were used to schedule mine production. The production schedule considers the processing of DeLamar and Florida Mountain Area oxide and mixed material by crushing and heap leaching, with some of the DeLamar Area material requiring agglomeration prior to leaching. DeLamar and Florida Mountain Area non-oxide material would be processed using flotation followed by cyanide leaching of the flotation concentrate.

An autonomous Railveyor light-rail haulage system will be used to transport ore from the open pits to the crusher facility. Utilizing the Railveyor system allows the opportunity to realize cost savings compared to typical truck haulage. This system, in conjunction with the planned solar and liquid natural gas electrical microgrid will reduce the overall fuel consumption and carbon footprint of the DeLamar Project.

The PFS has assumed owner mining instead of the more expensive contract mining. The production schedule was used along with additional efficiency factors, performance curves, and productivity rates to develop the first-principal hours required for primary mining equipment to achieve the production schedule. Primary mining equipment includes drills, loaders, hydraulic shovels, and haul trucks. Support, blasting, and mine maintenance equipment will be required in addition to the primary mining equipment.

The PFS envisions the use of two process methods for the recovery of gold and silver:

1. Lower-grade oxide and mixed materials will be processed by crushed-ore cyanide heap leaching; and

2. Non-oxide material will be processed using grinding followed by flotation, and very fine grinding of flotation concentrate for agitated cyanide leaching.

Heap-leach and milling ores will be coming from both the Florida Mountain and DeLamar Areas. Pregnant solutions from the heap-leach operation and from the milling operation will be processed by the same Merrill-Crowe zinc cementation plant. Processing will start with heap leaching in the first two years of operation. Milling of higher-grade non-oxide ore will start in the third year of operation.

Both Florida Mountain and DeLamar Area oxide and mixed ore types have been shown to be amenable to heap-leach processing following crushing. Material will be crushed in three stages to a nominal size of 80% finer than (P80) 12.7-millimeter (0.5 inches), at a rate of 35,000 tpd. About 45% of DeLamar Area ore is expected to require agglomeration.

Crushed and prepared ore will be transferred to the heap-leach pad using overland conveyors and stacked on the heap using portable or grasshopper conveyors and a radial stacking system. Pregnant leach solution will be collected at the base on the heap leach and transferred to the Merrill-Crowe processing plant for recovery of precious metals by zinc precipitation. The precipitate will be filtered, dried, and smelted to produce gold and silver doré bullion for shipment off site.

The milling process will start with primary crushing of the ore to a nominal P80 of 120 millimeter (4.72 inches), followed by grinding in a SAG mill-ball mill circuit to a P80 of 150 microns. The ball mill discharge will be pumped to hydrocyclones, with the hydrocyclone overflow advancing to flotation and the underflow returning to the ball mill. The mill will have a nominal capacity of 6,000 tpd.

The flotation circuit will produce a sulfide concentrate that will recover gold and silver from the ore. This flotation concentrate will be reground to a nominal P80 of 20 microns before being leached in agitated leach tanks. Pregnant solution will be separated using a CCD circuit that employs dewatering cyclones and thickeners. The pregnant solution is then sent to the Merrill-Crowe plant and gold smelting facility to produce gold and silver doré bullion.

The flotation tailing stream will be thickened and pumped to the tailing storage facility. The concentrate leach residue will be sent to cyanide destruction, then stored in a separate concentrate leach tailing storage facility.

Recoveries were applied based on recommendations of the relevant author of the DeLamar Report. Recoveries are shown in the table below. The oxide and mixed recoveries assume crushed heap leaching for oxide and mixed material, and flotation milling for non-oxide material. Florida Mountain Area non-oxide material uses recovery Equation and Equation to estimate the recoveries based on gold and silver grades respectively.

The infrastructure for the DeLamar Project has been developed to support mining and processing operations. This includes the access road to the facilities, power supply, Railveyor, communication, heap-leach pads, process plant, and ancillary buildings. This also includes haul roads within the mining area as well as the mine waste storage facilities.

The main access to the DeLamar Project is via gravel roads from Jordan Valley, Oregon, as used for previous mining at DeLamar. The existing DeLamar Project site access road is located on the east side of Henrietta Ridge extending from the DeLamar Road across Jordan Creek to the western side of the existing reclaimed Kinross tailing impoundment. This existing site access road is expected to become unusable due to its proximity to the proposed Milestone pit haul road and DeLamar West WRSF. Therefore, this PFS proposes relocating the site access road to the west side of Henrietta Ridge.

Haul road access between the DeLamar Area mine and Florida Mountain Area will need to be improved for use with the proposed mining equipment. This access will be utilized for delivery of all consumables, as well as any required construction materials and equipment. This will also be the primary access for all personnel working at the Florida Mountain Area.

The electrical power demand at the DeLamar Project facilities is currently estimated at 13.5 MW for initial heap-leach process operations, with an additional load of 9.8 MW for the mill circuit. The demand will vary according to the quantity of each ore type to be processed. The average load for the mine is forecast to be 11.6 MW (Table 18.1) with a peak demand of 23.4 MW. Lifetime electricity consumption is estimated to be 1.8 million MWh.

Existing electrical infrastructure on the DeLamar Project site consists of a 69 kV transmission line operated by Idaho Power Company. Significant upgrades to existing electrical infrastructure would be required to meet the anticipated load increase associated with the DeLamar Project, including construction of new 138 kV transmission lines, substations and tap station upgrades. To reduce capital expenditures of energy infrastructure, ensure power supply resilience and reduce emissions, Integra plans to power the project through an on-site microgrid with a solar electrical generation system and an LNG plant.

The DeLamar Project will utilize a Railveyor light rail haulage system to transport ore from the open pits to the crusher facility. The Railveyor system is an autonomous materials haulage system consisting of transport trains, light-rails, electrical drive stations, and materials loading and discharge stations. The system functions similar to a conveyor, but is designed to be modular and relocatable, allowing improved operational flexibility and lower cost. By leveraging the Railveyor system, the DeLamar Project has a unique opportunity to realize cost savings compared to typical truck haulage, while reducing its overall fuel consumption and carbon footprint and automating many essential functions that typically would require on-site personnel.

The heap-leach pads ("HLP" or "HLPs") will be located immediately north of the crushing facility in portions of Sections 3, 4, 9 and 10, Township 5 South, Range 4 West. The site slopes northerly toward Jordan Creek at an average gradient of 12.5 percent. The HLPs will be constructed in two phases. The phase 1 portion will be constructed on a feature locally identified as Jacobs Ridge and into an adjacent valley to the west (herein referred to as the "unnamed gulch" or the "valley"). The site is generally underlain with a basalt which is overlain with a thin veneer of colluvium derived from weathering of the basalt and interbeds of tuff. Upper portions of the HLPs are underlain with porphyritic latite lava flows. The northern extent of the Jacobs Ridge pad area is underlain by a Miocene age rhyolite dike or plug. Geotechnical drilling in the Jacobs Ridge portion of the site in 1988 identified discontinuous layers of weathered tuff that had low shear strength. An initial auger drilling program on the western side of the site did not encounter the tuffaceous material encountered on Jacobs Ridge.

Phase 2 portion of the HLP will consist of a westerly extension of the pad and tying in the area between the west side of the Jacobs Ridge pad and the east side of the phase 1 valley pad. Construction of phase 2 will begin two years ahead of when the extended pad is needed, assumed in year 3 of operation. Phase 2 construction will be performed in the same sequence of activities and will add approximately 30% to the pad footprint. The total volume of ore to be placed on the HLP is between 95 million tonnes and 100 million tonnes which may include up to 2 million tonnes placed at the southern end of the Jacobs Ridge portion of the phase 1 pad to minimize recovery time from the final ore placed on the pad.

The primary flotation TSF for the DeLamar Project will be located in Sections 30 and 31, Township 4 South, Range 4 West, and Sections 25 and 36, Township 4 South, Range 5 West, in Slaughterhouse Gulch, approximately 6.0 kilometers (3.7 miles) west of the new mill site. Slaughterhouse Gulch is a natural drainage that descends to the south primarily on State and BLM lands. The TSF will be a zoned earth and rockfill embankment that will be located where the valley narrows approximately 1km (0.6 miles) north of its confluence with Jordan Creek. The Slaughterhouse Gulch TSF will impound flotation tailing that have not been processed by cyanidation and therefore will not be lined in accordance with IDEQ Rules 58.01.013. The earth dam will be designed in accordance with Idaho dam safety regulation IDAPA 37 - DEPARTMENT OF WATER RESOURCES Water Allocations Bureau 37.03.05 - Mine Tailings Impoundment Structures.

The concentrate leach tailing storage facility ("CLTSF") will be a smaller, 26 hectare (64.2 acre) impoundment for containment of flotation concentrates from the milling process after they have been leached with cyanide to remove precious metals. To aid in settling, this fine material (P80 of 20 microns) will be blended with a small stream of coarser flotation tailing in roughly a 1:1 blend. The location of this CLTSF is immediately south of the HLP at the head of the unnamed drainage. The construction of the CLTSF in this location will involve placing fill from the Jacobs Ridge pad area to provide initial stormwater storage and then installing a liner system in year 2 that will meet the lining requirements of the IDEQ Rules 58.01.13 - Rules for Ore Processing by Cyanidation. In accordance with the regulation, the lining system will consist of 61 centimeters (24 inches) of compacted clay overlain with an 80-mil thick HDPE liner - or approved equivalent. The downstream side of the TSF will be constrained by crushed ore placed in the south end of the HLPs. A geotextile will be placed on the ore to allow drainage from the CLTSF into the ore to enhance consolidation of the tailing during operation and following closure. Excess fluids will be decanted from the surface of the impoundment and pumped back to a tank for re-introduction into the process water stream. Since this impoundment will be constructed in accordance with the IDEQ Cyanide Rules, in may also be used for temporary storage of excess fluids containing cyanide due to precipitation events on the HLP.

The proposed heap-leach facility will be located between the DeLamar and Florida Mountain Area pits. The primary crusher and process facilities will be located just south of the HLPs. Ore will be conveyed from the primary crusher to oxide or non-oxide coarse ore stockpiles accordingly.

WRSFs, along with backfill areas, have been designed for the PFS to contain the waste material mined from the different pit phases. A single WRSF design is planned for the Florida Mountain Area along with a two backfill dumps into the Florida Mountain Area phase 1 and 2 pits. Material from Florida Mountain Area phase 1 will be placed into the primary WRSF. Phase 2 waste material will also be placed into the primary WRSF except for some upper areas of the pit where some waste will be backfilled. Phase 3 waste material is planned to be placed into the backfill dump as available while the remaining waste material will be placed into the Florida Mountain Area WRSF. The total capacity of the WRSF is 32.2 million cubic meters (42.1 million cubic yards). The remaining 23.4 million cubic meters (30.6 million cubic yards) of waste material will be placed into backfill.

Three WRSF designs were created for the DeLamar Area which includes a West WRSF, East WRSF, and a North WRSF. The West and East WRSFs are intended for storage of material from the DeLamar Main phase 1 pit. Both dump designs include a roadway that will be built into the WRSFs to allow haulage through the main pit exits for both DeLamar Main and Sullivan Gulch pits. The East WRSF creates its haulage road through a valley to the south of the deeper Sullivan Gulch phase 2 pit. This road is anticipated to be in place well before the mining of Sullivan Gulch phase 2. The total West DeLamar WRSF total capacity is 5.9 million cubic meters (7.7 million cubic yards). After the roadway is completed, the East WRSF is to be expanded to the south. The total East DeLamar WRSF total capacity will be 50.0 million cubic meters (65.4 million cubic yards).

The North WRSF will be located in a valley to the north of the Main and Sullivan Gulch pits. This will be used for the Main pit phase 2 waste along with Sullivan Gulch pit waste. The designed capacity of the North WRSF is 26.4 million cubic meters (34.5 million cubic yards). As available, additional waste will be placed into the Main phase 1 pit and from the Main phase 2 pit as backfill. Additional backfill material will be placed into the Main phase 2 pit from Sullivan Gulch phase 1 mining.

Other buildings located on or near the process facilities pad include the administration/change building, a substation, assay lab, Merrill-Crowe plant, and water treatment plant.

It is anticipated that there will be several freshwater wells on-site that will provide the requirements of the DeLamar Project. Fresh water will be stored in a fresh/fire water tank that will have reserve storage dedicated for fire protection. The balance of the fresh/fire water volume will be utilized to supply the demands of the process as well as mine dust suppression.

Stormwater from the site will be managed as contact and non-contact stormwater. Non-contact stormwaters are the flows that do not come in contact with ore or mine processing facilities. Non-contact flows will be diverted and conveyed around the sites and directly discharged to existing stream channels. Contact stormwater will be utilized within the process to the greatest extent that allows the process to maintain a neutral balance. If there is excess contact water within the process, the excess will be routed to a water treatment plant. There is an existing water treatment plant at the project site. An allowance has been included for additional water treatment capacity consisting of a plant with solids separation and treatment, as required, to allow for discharge to existing stream channels or re-use in the process system.

Mine site personnel requirements are shown in the table below. This includes administrative, mining, and processing. In addition, there would be approximately 80 additional personnel working on-site during construction.

The review and approval process for the PoO by the BLM constitutes a federal action under the National Environmental Policy Act ("NEPA") and BLM regulations. Thus, for the BLM to process the PoO, the BLM is required to comply with the NEPA and prepare either an Environmental Assessment, or an Environmental Impact Statement ("EIS"). Based on discussions with the BLM, Integra anticipates an EIS will be required to comply with NEPA.

Integra has contracted qualified third parties to perform environmental adequacy reviews of all available existing environmental baseline reports and data compiled from 1979 through present. Additionally, an EA was approved in 1987 for the DeLamar Silver Mine and an EIS was approved in 1995 for the Stone Cabin Mine by previous operators for the site.

In 2020, Integra conducted a technical adequacy audit of all existing environmental information, and began the collection of surface water hydrology and quality, ground water hydrology and quality, geochemistry, water rights and geotechnical/engineering.

Baseline studies for surface water were initiated in spring of 2020 and ground water studies were initiated in the spring of 2020. Geotechnical investigations for site features commenced in 2021 and geochemical fieldwork and kinetic testing commenced in 2020 and will continue into 2022/2023.

In 2021, Integra developed certain plans of study and, working closely with the BLM and state agencies, completed the review and approval of the initial environmental baseline work plans. Baseline surveys initiated in accordance with the 2021 plans of study and baseline technical reports are underway. Additional plans of studies and collection of data will be undertaken in 2022.

The data collection and technical reports are scheduled to be completed in the second half of 2022. The entire DeLamar mining district has been studied extensively, both historically and currently; therefore, ensuring scientific integrity of the methodologies and analysis used to collect the data and ultimately a meaningful analysis would be conducted allowing for a reasonable comparative assessment of the alternatives.

The Mine Plan of Operations ("MPO") is submitted to the BLM for any surface disturbance in excess of five acres (2.02 hectares). The MPO describes the operational procedures for the construction, operation, and closure of the project. As required by the BLM, the MPO includes a waste-rock management plan, quality assurance plan, a storm water plan, a spill prevention plan, reclamation plan, a monitoring plan and an interim management plan. In addition, a reclamation report with a Reclamation Cost Estimate ("RCE") for the closure of the project is required. The content of the MPO is based on the mine plan design and the data gathered as part of the environmental baseline studies. The MPO includes all mine and processing design information and mining methods. The BLM determines the completeness of the MPO and, when the completeness letter is submitted to the proponent, the NEPA process begins. The RCE is reviewed by BLM and the bond is determined prior to the BLM issuing a decision on the MPO.

The MPO will be submitted for the DeLamar Project when operational and baseline surveys are complete and operations and design for the DeLamar Project are at a level where a MPO can be developed to the necessary level of detail. Submittal of the MPO is likely to occur in the first half of 2023.

Approval of any MPO and reclamation plan by the federal agencies for the DeLamar Project as well as accordance with Section 404 requires an environmental analysis under the NEPA. NEPA requires federal agencies study and consider the likely environmental impacts of the proposed action before taking whatever federal action is necessary for the project to proceed.

The purpose and need for the DeLamar Project would be to conduct open pit mining and ore processing, which would disturb over 809 hectares (2,000 acres) of unpatented and patented mining claims and state lands within the project area and complete reclamation and closure activities, as well as long-term water treatment, to produce silver and gold from mineralized material of the estimated mineral resources. As a result, Integra anticipates that an EIS will be required to meet agency NEPA requirements.

The BLM will be the lead federal agency for the preparation of the EIS, and other agencies will be cooperating agencies. The EIS and associated Record of Decision ("ROD") effectively drives the entire permitting process timeline.

Several other federal, state and local county authorizations and/or permits will be required.

Please refer to "General Development of the Business - Three Year History" section above for details on recent permitting activities.

The DeLamar Project is located in rural Owyhee County, close to the Oregon border. The closest substantial community is Jordan Valley, in Malheur County Oregon. This community is primarily an agricultural based economy. However, when the mine previously operated in the 1980s and 1990s many of the employees lived in Jordan Valley.

Please refer to "General Development of the Business - Three Year History" section above for details on recent social activities.

The table below summarizes the estimated capital costs for the DeLamar Project. The LOM total capital costs are estimated as $589.5 million, including $307.6 million in preproduction capital (including working capital and reclamation bond) and $281.8 million for expansion and sustaining capital. Sustaining capital includes $30.8 million in reclamation costs. The estimated capital costs are inclusive of sales tax, engineering, procurement and construction management ("EPCM") and contingency.

(3) Major mining equipment assumes financing by equipment vendor with 10% down; principal payments included under sustaining capital column and interest payments included in operating costs.

(4) Sustaining capital showed in this table includes expansion capital (non-oxide plant) and principal payment of mining equipment leases (see note 3 above).

(6) Cash deposit = 20% of bonding requirement. Released once reclamation is completed.

The table below shows the estimated LOM operating costs for the DeLamar Project. Operating costs are estimated to be $12.93 per tonne processed for the LOM. This includes mining costs, which are estimated to be $1.90 per tonne mined. The total cash cost is estimated to be $923 per ounce of AuEq¹⁰ and site level AISC are estimated to be $955 per ounce of AuEq.

Economic sensitivities of the DeLamar Project to changes in metal prices were evaluated based on constant gold to silver ratios as shown in the below table.

The after-tax sensitivity to revenues, capital, and operating costs is shown in the below figure.

Please see "General Development of the Business - Trends and Outlook" section above for further details on the Company's current and contemplated exploration and development activities.

There is the potential to lower project capital costs by foregoing mill processing and instead operate a heap-leach only project. In this scenario, a high percentage of the current heap-leach reserves would be processed at the 35,000 tpd rate envisioned in the PFS. LOM capital expenditures would decrease significantly as expansion capital, such as non-oxide plant and tailing facilities, would not be required. A decision to construct and initiate mill processing (stage 2) could be exercised at any time, providing the flexibility to respond to changing market conditions and thereby reduce project risk.

A heap-leach only approach could reduce risk and provide greater flexibility to respond to the prevailing economic environment in connection with a decision to pursue a milling scenario later.

Please see the DeLamar Report on the Company's website at www.integraresources.com for additional details on potential opportunities.
