VISTA GOLD CORP.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Dollar amounts in U.S. dollars and in thousands, except share amounts and per ounce amounts)

1. Nature of Operations and Basis of Presentation

Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) operate in the gold mining industry. We are focused on evaluation, acquisition, exploration and advancement of gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements with other mining companies, or outright sales of assets for cash and/or other consideration. We undertake programs designed to improve the value of our gold projects through exploration drilling and/or technical studies focused on optimizing previous engineering work. 

The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) in Northern Territory, Australia. Mt Todd is the largest undeveloped gold project in Australia. In January 2018, the Company received authorization for the last major environmental permit for Mt Todd. In September 2019, Vista announced the positive results of an updated preliminary feasibility study (the “2019 PFS”) for Mt Todd. Process improvements reflected in the 2019 PFS have resulted in improved estimated gold recovery and increased estimated gold production at Mt Todd.

As of September 30, 2019, the Company also holds 7.8 million common shares of Midas Gold Corp. (“Midas Gold Shares”), a non-core project in Mexico subject to a third-party option agreement, and royalty interests in the United States and Indonesia. 

The interim Condensed Consolidated Financial Statements (“interim statements”) of the Company are unaudited. In the opinion of management, all adjustments and disclosures necessary for a fair presentation of these interim statements have been included. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. These interim statements should be read in conjunction with the Company’s Consolidated Financial Statements for the year ended December 31, 2018 as filed with the United States Securities and Exchange Commission and Canadian securities regulatory authorities on Form 10-K, as amended on Form 10-K/A on August 15, 2019. The year-end balance sheet data was derived from audited financial statements and, in accordance with the instructions to Form 10-Q, certain information and footnote disclosures required by United States generally accepted accounting principles have been condensed or omitted. 

References to $ are to United States dollars and A$ are to Australian dollars.

2.  Significant Accounting Policies

Lease Accounting

In February 2016, the FASB issued ASU No. 2016-02, Leases. This new standard established a right-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The Company adopted the standard on January 1, 2019 using the modified retrospective approach. We recognized additional liabilities of $186 on adoption, with corresponding ROU assets of the same amount, based on the present value of the remaining lease payments. Adoption of the standard did not affect lease classification or expense recognition. The Company does not include short term leases in its ROU asset and lease liability calculations. As of September 30, 2019, the ROU asset was $113 and the lease liability was $113, comprised of $97 included in accrued liabilities and other, and $16 in non-current liabilities. The Company’s leases had remaining terms ranging from 0.5 to 2.5 years as of September 30, 2019.

3. Short-term and Other Investments

Short-term investments

As of September 30, 2019, and December 31, 2018, the amortized cost basis of our short-term investments was $3,111 and $6,997, respectively. The amortized cost basis approximates fair value at September  30, 2019 and December 31, 2018. Short-term investments at September 30, 2019 and December 31, 2018 were comprised of U.S. government treasury bills and/or notes, all of which had maturity dates on the date of purchase greater than 90 days but less than one year. 

Other investments - Midas Gold Shares 

The Company’s investment in Midas Gold Shares was recorded at fair value in the Condensed Consolidated Balance Sheets. Subsequent changes in fair value are recorded in the Condensed Consolidated Statements of Comprehensive Income/(Loss) in the period in which they occur. 

As of September 30, 2019, and December 31, 2018, the Company held 7,802,615 shares of Midas Gold valued at $3,511 and $5,462 respectively. The unrealized loss on these shares was $234 and $1,951 for the three and nine months ending September 30, 2019, respectively. The unrealized loss on these shares was $274 and the unrealized gain was $1,754 for the three and nine months ending September 30, 2018, respectively.

Guadalupe de los Reyes, Mexico		—		275
	$	2,146	$	2,421

During October 2017, we entered into an agreement (the “Option Agreement”) to option our interest in the Guadalupe de los Reyes gold and silver project in Sinaloa, Mexico (“Los Reyes”) to Minera Alamos Inc. and its subsidiary Minera Alamos de Sonora S.A. de C.V. (“Minera Alamos”). In June 2019, the Option Agreement was assigned from Minera Alamos to ePower Metals Inc. by way of assignment agreement (the “Assignment Agreement”), with our consent. ePower Metals Inc. subsequently changed its name to Prime Mining Corporation (“Prime Mining”). The Assignment Agreement provides that in certain circumstances, the rights under the Option Agreement will revert from Prime Mining to Minera Alamos.

Pursuant to the terms of the Option Agreement and the Assignment Agreement, we granted Minera Alamos or Prime Mining, as applicable, (the “Optionholder”) an exclusive right and option right to earn a 100% interest in the Los Reyes project by:

· making payments totaling $6,000, comprised of a payment of $1,500 made at the execution of the Option Agreement (the “Option Grant Date”); two successive payments of $1,500 each to be made at the one-year and two-year anniversaries of the Option Grant Date; and a final $1,500 payment to be made before the four-year anniversary of the Option Grant Date;

· maintaining the concessions comprising the Los Reyes project in good standing;

· fulfilling all obligations to the Ejido La Tasajera (the “Ejido”) as set out in the temporary occupation contract between us and the Ejido;

· granting us a capped net smelter return royalty (“NSR”) on production from open pit mining (the “Open Pit NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz) up to an aggregate of $2,000 in royalty payments;

8

· granting us a perpetual NSR on production from underground mining (the “Underground NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz); and

· granting us the right to assume a 49% non-carried interest in an underground project if the Optionholder decides to develop an underground mine at the Los Reyes project (the “Back-in Right”).

The Option Agreement provides that all cash payments are non-refundable and optional to the Optionholder, and in the event the Optionholder fails to pay any of the required amounts as set out in the Option Agreement, or fails to comply with its other obligations, the Option Agreement will terminate and the Optionholder will have no interest in the Los Reyes project. Provided it is not in breach of the Option Agreement, the Optionholder may, at its discretion, accelerate the above payment schedule. 

Subject to the Optionholder timely making all the option payments, and fulfilling its other obligations with respect to the Option Agreement, we will transfer 100% of the shares of the Company’s 100% owned subsidiary Minera Gold Stake S.A. de C.V., the entity which owns the Los Reyes project, to the Optionholder and the Open-Pit NSR and Underground NSR will be granted to us.

If the Optionholder discovers and decides to develop an underground mine at the Los Reyes project and we exercise the Back-in Right, we and the Optionholder have agreed to form a joint venture to develop and operate the underground mine. If the joint venture is formed, the Underground NSR will terminate.

In October 2018, the Company agreed to extend the due date for the second $1,500 option payment under the Los Reyes Option Agreement by six months to April 23, 2019, at which time the payment was made. As consideration for the deferral, the Company received an additional $150 in cash, $50 paid on October 24, 2018 and $100 paid on January 23, 2019. In addition, Minera Alamos paid interest of $67 at a rate of 1.5% per month on the unpaid balance of the $1,500 payment beginning January 24, 2019.

The Company has determined that control of the Los Reyes project has not been transferred for accounting purposes. Therefore, the first option payment of $1,500 received in October 2017 and the $150 for extension of the second option payment were accounted for as a reduction to carrying value. Receipt of the second option payment of $1,500 and interest of $67 during April 2019 reduced the carrying value to zero and resulted in recognition of $1,392 as a deferred option gain. The third Los Reyes project option payment of $1,500 was received from Prime Mining in October 2019. This receipt will be recorded as additional deferred option gain. In addition, potential royalty revenue and future option payments have not been recognized for accounting purposes.

Stock-Based Compensation

Under the Company’s stock option plan (the “Plan”), we may grant options to purchase common shares in the capital of the Company (“Common Shares”) to our directors, officers, employees and consultants. The maximum number of Common Shares that may be reserved for issuance under the Plan, together with all other stock-based compensation arrangements, which include restricted share units (“RSUs”) currently outstanding under the Company’s long term equity incentive plan (“LTIP”) and deferred share units (“DSUs”) issuable pursuant to the Company’s deferred share unit plan (“DSU Plan”), is a variable number equal to 10% of the issued and outstanding Common Shares on a non-diluted basis at any one time. In 2018, the Company issued phantom units to be settled in cash. Options, RSUs, DSUs, and phantom units are granted from time to time at the discretion of the Board of Directors of the Company (the “Board”), with vesting periods and other terms as determined by the Board.

Stock-based compensation expense for the three and nine months ended September 30, 2019 and 2018 is as follows: 

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018

As of September 30, 2019, unrecognized compensation expense for stock options, RSUs, and phantom units was $88, $463, and $96,  respectively, which is expected to be recognized over weighted average periods of 0.8, 1.3, and 1.3 years, respectively.

A portion of the RSU awards vest on a fixed future date provided the recipient continues to be affiliated with Vista on that date. Other RSU awards vest subject to certain performance and market criteria, including the accomplishment of certain corporate objectives and the Company’s share price performance. The minimum vesting period for RSUs is one year.  

During the nine months ended September 30, 2019 and 2018, the Company withheld Common Shares with an equivalent value to meet the employee withholding tax obligations which resulted from RSUs that vested in the period. Common Shares withheld are considered cancelled/forfeited.

Deferred Share Units

In May 2019, the Company’s shareholders approved the DSU Plan. The DSU Plan provides for granting of DSUs to non-employee directors. DSUs vest immediately, however the Company will issue one Common Share for each DSU only after the non-employee director has ceased to be a director of the Company. Additionally, in May 2019, the Company’s shareholders approved an amendment to the LTIP such that non-employee directors are excluded from future grants under the LTIP. At the time the DSU Plan was approved, the Board granted 366,000 DSUs and the Company recognized $209 in DSU expense.

The following table summarizes the DSUs outstanding as of September 30, 2019:

		Weighted average

Phantom Units

In 2018, the Company granted a total of 265,000 phantom units to certain employees. The value of each unit is equal to the Company’s share price on the vesting date and is payable in cash. The phantom units vest on fixed future dates provided the recipient continues to be affiliated with Vista on those dates. The Company accounts for these units as awards classified as liabilities with $14 included in current liabilities as of September 30, 2019. The Company recognized $28 and $72 of compensation expense for these phantom units in the three and nine months ended September 30, 2019, respectively.  

A summary of unvested phantom units as of September 30, 2019 is set forth in the following table:

7.  Commitments and Contingencies

Our exploration and development activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. As such, future expenditures that may be required for compliance with these laws and regulations cannot be predicted. We conduct our operations in an effort to minimize effects on the environment and believe our operations are in compliance with applicable laws and regulations in all material respects.

Under our agreement with the Jawoyn Association Aboriginal Corporation (the “JAAC”), the JAAC will be entitled to an annual cash payment, or payment in kind, equal to 1% of the value of the annual gold production from the current mining licenses, and a 1% NSR on other metals, subject to a minimum payment of A$50 per year. In addition, we have agreed to offer the JAAC the opportunity to establish a joint venture with Vista holding a 90% participating interest and the JAAC holding a 10% participating interest in Mt Todd.

8.  Fair Value Accounting

The following table sets forth the Company’s assets measured at fair value by level within the fair value hierarchy. As required by accounting guidance, assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. 

	Fair value at September 30, 2019
	Total		Level 1		Level 3
Other investments (Midas Gold Shares)	$	3,511	$	3,511	$	—

	Fair value at December 31, 2018
	Total		Level 1		Level 3
Other investments (Midas Gold Shares)	$	5,462	$	5,462	$	—
Used mill equipment (non-recurring)	$	5,500	$	—	$	5,500

Our investment in Midas Gold Shares is classified as Level 1 of the fair value hierarchy as it is valued at quoted market prices in an active market.

The used mill equipment is classified as Level 3 of the fair value hierarchy as its value at December 31, 2018 was based on an independent third-party valuation. As of September 30, 2019,  management had not identified sufficient changes in conditions to require an update to the independent third-party evaluation. The mill equipment is included in plant and equipment on the Condensed Consolidated Balance Sheets for each period presented. There have been no transfers between levels in 2019, nor have there been any changes in valuation techniques.

9.  Geographic and Segment Information

The Company has one reportable operating segment. We evaluate, acquire, explore and advance gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions.  These activities are currently focused principally in Australia. We reported no revenues during the three and nine months ended September 30, 2019 and 2018.  Geographic location of mineral properties and plant and equipment is provided in Notes 4 and 5, respectively.

ITEM 2.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion and analysis should be read in conjunction with our unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2019, and the related notes thereto, which have been prepared in accordance with generally accepted accounting principles in the United States. This discussion and analysis contains forward-looking statements and forward-looking information that involve risks, uncertainties and assumptions.  Our actual results may differ materially from those anticipated in these forward-looking statements and information as a result of many factors.  See section heading “Note Regarding Forward-Looking Statements” below.

All dollar amounts stated herein are in U.S. dollars in thousands, except per share and per ounce amounts and currency exchange rates unless specified otherwise. References to $ are to United States dollars and to A$ are to Australian dollars.

Overview

Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) operate in the gold mining industry. We are focused on the evaluation, acquisition, exploration and advancement of gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements with other mining companies, or outright sales of assets for cash and/or other consideration.  We undertake programs designed to improve the value of our gold projects through exploration drilling and/or technical studies focused on optimizing previous engineering work. We do not currently generate cash flows from mining operations.

The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) in the Northern Territory (“NT”) Australia.  Mt Todd is the largest undeveloped gold project in Australia. The Company has invested substantial amounts to evaluate, engineer, permit and de-risk the Project, and we believe these efforts have added to the underlying value of the Project. In January 2018, the Company received authorization for the last major environmental permit for Mt Todd and announced the positive results of an updated preliminary feasibility study for Mt Todd (the “2018 PFS”). Subsequently, we announced additional metallurgical testing results that demonstrated improved gold recovery compared to the 2018 PFS. These results and other findings were incorporated into a preliminary feasibility study, which was announced in September 2019 (the “2019 PFS”). The 2019 PFS successfully confirmed the efficiency of ore sorting across a broad range of head grades, the natural concentration of gold in the screen undersize material prior to sorting, the economics of fine grinding and the resulting improved gold recoveries, and the selection of FLSmidth's VXP mill as the preferred fine grinding mill. 

As of September 30, 2019, the Company also holds 7.8 million common shares in the capital of Midas Gold Corp. (“Midas Gold Shares”), a non-core project in Mexico subject to a third-party option agreement, and royalty interests in the United States and Indonesia.

Results from Operations

Summary

Consolidated net loss for the three months ended September 30, 2019 and 2018 was $2,498 and $2,062 or $0.02 and $0.02 per share, respectively. Consolidated net loss for the nine months ended September 30, 2019 and 2018 was $8,194 and $4,933 or $0.08 and $0.05 per share, respectively. The principal components of these year-over-year changes are discussed below.

The Company had $7,179 of working capital and no debt as of September 30, 2019.

Exploration, property evaluation and holding costs

Exploration, property evaluation and holding costs were $1,401 and $960 during the three months ended September 30, 2019 and 2018, respectively; and $3,294 and $3,560 for the nine months ended September 30, 2019 and 2018, respectively. These costs are predominantly project holding and discretionary costs associated with Mt Todd. For the nine months ended September 30, 2019, project holding costs (which are necessary to preserve our property rights and meet our safety, regulatory, social, and environmental responsibilities) were lower compared to the same periods during 2018 as water discharge from the Batman pit decreased because of comparatively lower precipitation during the most recent wet season. This also reduced the scope of certain baseline monitoring activities. In addition, the Australian dollar was approximately 8% weaker versus the United States dollar in 2019 compared to 2018. For the three months ended September 30, 2019, project holding costs were higher than the same period in 2018 due to the costs to complete the 2019 PFS.

Discretionary costs during the three and nine months ended September 30, 2019 were also lower than the same periods during 2018.

Exploration, property evaluation and holding costs for the three months ended September 30, 2019 and 2018 included non-cash stock-based compensation of $58 and $67, respectively; and $120 and $219 for the nine months ended September 30, 2019 and 2018, respectively.

Corporate administration

Corporate administration costs were $865 and $969 during the three months ended September 30, 2019 and 2018, respectively; and $3,079 and $3,280 during the nine months ended September 30, 2019 and 2018, respectively. Administrative expenses were lower during the three months ended September 30, 2019 compared to the same period in 2018 because of cost savings related to bringing certain investor relations costs in house that were previously outsourced.

Depreciation

Depreciation costs were $14 and $12 during the three months ended September 30, 2019 and 2018, respectively; and $40 and $252 during the nine months ended September 30, 2019 and 2018, respectively. The majority of the Company’s fixed assets were fully depreciated by December 31, 2018, resulting in lower 2019 depreciation costs.

Non-operating income and expenses

Gain/(Loss) on other investments

Gain/(Loss) on other investments was $(234) and $(274) for the three months ended September 30, 2019 and 2018, respectively and $(1,951) and $1,754 for the nine months ended September 30, 2019 and 2018, respectively.  These amounts result from changes in fair value of our Midas Gold Shares.

Financial Position, Liquidity and Capital Resources

Operating activities

Net cash used in operating activities was $5,190 and $6,347 for the nine months ended September 30, 2019 and 2018, respectively. The decreased use of cash in 2019 resulted from $1,165 less cash used for working capital items, most notably being a $1,178 reduction in accounts payable and accrued liabilities during the first nine months of 2018, after which the Company carried consistently lower balances.

Investing activities

Net cash provided by investing activities was $5,513 and $6,185 for the nine months ended September 30, 2019 and 2018, respectively. Disposition of short-term investments, net of acquisitions, decreased during 2019 by $2,229

15

compared to the same period in 2018. This reduction in net dispositions of short-term investments was possible because cash requirements for operations were lower and other sources of cash were available to us, notably the $1,667 received from Minera Alamos de Sonora S.A. de C.V. (“Minera Alamos”) under the terms of the Guadalupe de los Reyes Option Agreement (as defined below).

Financing activities

During the nine months ended September 30, 2019 and 2018, cash of $10 and $106, respectively, was used in financing activities. These amounts result from uses of cash for payment of employee withholding tax obligations arising from the vesting of RSUs, in lieu of issuing common shares of the Company, offset by proceeds received from exercise of stock options.

Liquidity and capital resources

Our cash and short-term investments as of September 30, 2019 decreased to $4,495 from $8,068 at December 31, 2018 due mainly to expenditures for operating activities, offset partially by cash received from Minera Alamos under the terms of the Guadalupe de los Reyes Option Agreement. Our net working capital decreased to $7,179 at September 30, 2019 from $13,198 at December 31, 2018 due mainly to the decrease in cash and short-term investments to fund operating activities and the reduction in fair value of our Midas Gold Shares, offset partially by receipts from Minera Alamos.

We believe our existing working capital, comprised mostly of cash, short-term investments, and our Midas Gold Shares, will be sufficient to fully fund our currently planned corporate and project holding costs and discretionary programs for more than 12 months.

Vista has other potential future sources of non-dilutive financing that may be converted to additional working capital. These sources include the sale of non-core assets such as our used mill equipment, future option payments under the Guadalupe de los Reyes Option Agreement, and monetization of royalty interests held by the Company. The Company plans to increase its focus on monetizing these other sources of working capital as existing working capital decreases.

In addition to the existing working capital and other potential sources of non-dilutive financing highlighted above, the Company has an at-the-market offering agreement (the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”) to provide additional balance sheet flexibility at a low cost. Under the ATM Agreement the Company may, but is not obligated to, issue and sell common shares in the capital of the Company through Wainwright as sales manager in an at-the-market offering under a prospectus supplement for aggregate sales proceeds of up to $10,000. The ATM Agreement will remain in full force and effect, subject to an effective registration statement under the U.S. Securities Act of 1933, as amended, until the earlier of August 31, 2020, or the date that the ATM Agreement is terminated in accordance with the terms therein.

The long-term viability of Vista is dependent upon our ability to maintain our low expenditure profile, realize value from non-dilutive assets and, if necessary, issue additional equity to secure sufficient funding to advance significant value-adding programs that will focus on generating future cash flows and positive equity returns to our shareholders. The underlying value and recoverability of the amounts shown as mineral properties and plant and equipment in our Condensed Consolidated Balance Sheets are dependent on our ability to attract sufficient capital resources to execute our strategy and the ultimate success of our programs to enhance value, most importantly at Mt Todd.

Project Updates

Mt Todd Gold Project, Northern Territory, Australia

The following scientific and technical information about Mt Todd has been reviewed and approved by Mr. John Rozelle, Senior Vice President of Vista.  Mr. Rozelle is a qualified person as defined by Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

Environmental Approvals and Metallurgical Optimization Program

In January 2018, we announced that the “authorization of a controlled activity” at Mt Todd, as required under the Environment Protection and Biodiversity Act, as it relates to the Gouldian Finch, had been approved by the Australian Commonwealth Department of Environment and Energy. With this authorization, Vista has all major environmental approvals necessary to allow development of Mt Todd.

Vista initiated a second metallurgical optimization program following issuance of the 2018 PFS. The objective of this program was to determine overall gold recoveries at finer grind sizes and evaluate the efficiency of the FLSmidth VXP mills as opposed to the Glencore ISA mills, which were contemplated in the 2018 PFS. As a result of this test work and related leach recovery tests, a final grind size of 80% passing 40 microns (µm) was selected.The outcomes of our metallurgical testing and other findings were incorporated into an updated PFS (see 2019 PFS, below), which was issued in October 2019.

In support of the metallurgical test work, we completed four additional large diameter core holes and extracted approximately 6 tonnes of higher-grade material from the Batman deposit. We prepared two additional 2.5 tonne composite samples for high-pressure grinding roll (“HPGR”) crushing and sorting tests using the same equipment as previous test work. The two 2.5 tonne tests were prepared to confirm the efficiency of sorting higher-grade ores. Additional feasibility-study-level grinding tests with manufacturers of fine grinding mills were completed in order to obtain material for further metallurgical studies and specific operating data for future design and evaluation work. We also completed additional testing with an impeller manufacturer in order to achieve optimal efficiency at designed slurry densities and P80 product particle size.

17

In August 2019, we announced the results of the 2019 fine grinding tests completed on samples of various grade ranges, under the direction of Resource Development Inc. These tests confirm that the Mt Todd ore can be efficiently ground to a finer final product size with lower power consumption in the grinding circuit than estimated in the 2018 PFS. Leaching the finer final product size material reconfirmed higher recoveries at finer grind sizes.  It also demonstrated that at 40µm grind size, the tail grade is nearly constant, with minor changes easily definable within specific head-grade ranges. 

Vista’s latest metallurgic test programs have confirmed: (1) the efficiency of ore sorting across a broad range of head grades and the natural concentration of gold in the screen undersize material prior to sorting; (2) the efficiency of fine grinding and improved gold leach recoveries at an 80% passing grind size of 40 microns; and (3) the selection of FLSmidth VXP mill as the preferred fine-grinding mill.

2019 PFS

In September 2019, we announced the results of an updated preliminary feasibility study for the Mt Todd project and in October 2019 we filed a technical report entitled “NI 43-101 Technical Report Mt Todd Gold Project 50,000 tpd Preliminary Feasibility Study Northern Territory, Australia” with an effective date of September 10, 2019 and an issue date of October 7, 2019 (the “2019 PFS”).  The 2019 PFS was based on the results of metallurgical testing, a comprehensive review of the Project and the re-design of elements of the process flow sheet, and most importantly, grinding circuit design changes. Key inputs that changed in the 2019 PFS include higher gold recoveries due to the finer grind size, a higher gold price, and improved foreign exchange rates.

The process improvement efforts resulted in revised estimates that reflect reduced operating costs, increased gold recovery and higher gold production. In addition, we commissioned an independent benchmarking study to assess the appropriateness of capital and operating cost estimates, construction and ramp-up schedules, owner's costs and key components of the Mt Todd project. Recommendations from the study were incorporated, as appropriate, in the 2019 PFS. We also updated revenue, capital, and operating costs based on current market conditions and recent quotes from suppliers. 

The 2019 PFS evaluates two development scenarios: a 50,000 tpd project that develops more of the Mt Todd resource and generates a larger net present value (“NPV”) (the “Base Case”); and a smaller and higher-grade 33,000 tpd project (the “Alternate Case”). The Alternate Case of the 2019 PFS supersedes a similar study in the 2018 PFS, but is not deemed material. The Alternate Case is disclosed in the full technical report referenced below.

Highlights of the 2019 PFS Base Case are presented in the table below: 

	Years 1-5			Life of Mine (13 years)
Average Milled Grade (g Au/t)		0.96				0.82

Guadalupe de los Reyes Gold/Silver Project, Sinaloa, Mexico

During October 2017, we entered into an agreement (the “Option Agreement”) to option our interest in the Guadalupe de los Reyes gold and silver project in Sinaloa, Mexico (“Los Reyes”) to Minera Alamos Inc. and its subsidiary Minera Alamos. In June 2019, the Option Agreement was assigned from Minera Alamos to ePower Metals Inc. by way of assignment agreement (the “Assignment Agreement”), with our consent. ePower Metals Inc., subsequently changed its name to Prime Mining Corporation (“Prime Mining”). The Assignment Agreement provides that in certain circumstances, the rights under the Option Agreement will revert from Prime Mining to Minera Alamos.

Pursuant to the terms of the Option Agreement and the Assignment Agreement, we granted Minera Alamos or Prime Mining, as applicable, (the “Optionholder”) an exclusive right and option right to earn a 100% interest in the Los Reyes project by:

· making payments totaling $6,000, comprised of a payment of $1,500 made at the execution of the Option Agreement (the “Option Grant Date”); two successive payments of $1,500 each to be made at the one-year and two-year anniversaries of the Option Grant Date; and a final $1,500 payment to be made before the four-year anniversary of the Option Grant Date;

· maintaining the concessions comprising the Los Reyes project in good standing;

· fulfilling all obligations to the Ejido La Tasajera (the “Ejido”) as set out in the temporary occupation contract between us and the Ejido;

· granting us a capped net smelter return royalty (“NSR”) on production from open pit mining (the “Open Pit NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz) up to an aggregate of $2,000 in royalty payments;

· granting us a perpetual NSR on production from underground mining (the “Underground NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz); and

· granting us the right to assume a 49% non-carried interest in an underground project if Optionholder decides to develop an underground mine at the Los Reyes project (the “Back-in Right”).

The Option Agreement provides that all cash payments are non-refundable and optional to the Optionholder, and in the event the GdlR Optionholder fails to pay any of the required amounts as set out in the Option Agreement, or fails to comply with its other obligations, the Option Agreement will terminate and the Optionholder will have no interest in the Los Reyes project. Provided it is not in breach of the Option Agreement, the Optionholder may, at its discretion, accelerate the above payment schedule. 

Subject to the Optionholder timely making all the option payments, and fulfilling its other obligations with respect to the Option Agreement, we will transfer 100% of the shares of the Company’s 100% owned subsidiary Minera Gold Stake S.A. de C.V., the entity which owns the Los Reyes project, to the Optionholder and the Open-Pit NSR and Underground NSR will be granted to us.

If the Optionholder discovers and decides to develop an underground mine at the Los Reyes project and we exercise the Back-in Right, we and the Optionholder have agreed to form a joint venture to develop and operate the underground mine. If the joint venture is formed, the Underground NSR will terminate.

In October 2018, the Company agreed to extend the due date for the second $1,500 option payment under the Los Reyes Option Agreement by six months to April 23, 2019, at which time the payment was made. As consideration for the deferral, the Company received an additional $150 in cash, $50 paid on October 24, 2018 and $100 paid on January 23, 2019. In addition, Minera Alamos paid interest of $67 at a rate of 1.5% per month on the unpaid balance of the $1,500 payment beginning January 24, 2019. The third Los Reyes project option payment of $1,500 was received from Prime

21

Mining in October 2019. This receipt will be recorded as additional deferred option gain. In addition, potential royalty revenue and future option payments have not been recognized as income for accounting purposes.

Certain U.S. Federal Income Tax Considerations

Vista has been a “passive foreign investment company” (“PFIC”) as defined under Section 1297 of the U.S. Internal Revenue Code of 1986, as amended, in recent years and expects to continue to be a PFIC in the future. Current and prospective United States shareholders should consult their tax advisors as to the tax consequences of PFIC classification and the U.S. federal tax treatment of PFICs. Additional information on this matter is included in Vista’s Annual Report on Form 10-K for the year ended December 31, 2018, under “Part II. Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities — Certain United States Federal Income Tax Considerations for U.S. Residents.”

Cautionary Note to Investors Regarding Estimates of Mineral Reserves and Resources

Our technical report entitled “NI 43-101 Technical Report Mt Todd Gold Project 50,000 tpd Preliminary Feasibility Study Northern Territory, Australia” with an effective date of September 10, 2019 and an issue date of October 7, 2019. referenced herein uses the terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” as defined in Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Definition Standards”). These definitions differ from the definitions in the United States Securities and Exchange Commission (“SEC”) Industry Guide 7 (“SEC Industry Guide 7”) under the United States Securities Act of 1933, as amended (the “Securities Act”). Under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average metal price is used in any reserve or cash flow analysis to designate reserves, and the primary environmental analysis or report must be filed with the appropriate governmental authority.

25

In addition, the technical report uses the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” which are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that all or any part of a mineral deposit in these categories will ever be converted into reserves. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic, technical and legal feasibility. It cannot be assumed that all, or any part, of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically, technically or legally mineable. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures.

Accordingly, the technical report contains descriptions of our mineral deposits that may not be comparable to similar information made public by U.S. companies reporting under SEC Industry Guide 7.

The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC. These amendments became effective February 25, 2019 (the “SEC Modernization Rules”) and, following a two-year transition period, the SEC Modernization Rules will replace the historical property disclosure requirements for mining registrants that are included in SEC Industry Guide 7. The Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules until its fiscal year beginning January 1, 2021. Under the SEC Modernization Rules, the definitions of “proven mineral reserves” and “probable mineral reserves” have been amended to be substantially similar to the corresponding CIM Definition Standards and the SEC has added definitions to recognize “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” which are also substantially similar to the corresponding CIM Definition Standards; however there are differences in the definitions and standards under the SEC Modernization Rules and the CIM Definition Standards and therefore once the Company begins reporting under the SEC Modernization Rules there is no assurance that the Company’s mineral reserve and mineral resource estimates will be the same as those reported under CIM Definition Standards as contained in the technical report or that the economics for the Mt Todd project estimated in the technical report will be the same as those estimated in any technical report prepared by the Company under the SEC Modernization Rules in the future. 

Non-GAAP Financial Measures

In this report, we have provided information prepared or calculated according to United States generally accepted accounting principles (“U.S. GAAP”), as well as provided some non U.S. GAAP prospective financial performance measures. Because the non-GAAP performance measures do not have any standardized meaning prescribed by U.S. GAAP, they may not be comparable to similar measures presented by other companies. These measures should not be considered in isolation or as substitutes for measures of performance prepared in accordance with U.S. GAAP. There are limitations associated with the use of such non-GAAP measures. Since these measures do not incorporate revenues, changes in working capital and non-operating cash costs, they are not necessarily indicative of potential operating profit or loss, or cash flow from operations as determined in accordance with U.S. GAAP.

The non-GAAP measures Total Cash Costs, Cash Costs per ounce and All-in Sustaining Costs (AISC) per ounce are not, and are not intended to be, presentations in accordance with U.S. GAAP. As referenced in the 2019 PFS, these measures represent, respectively, our prospective cash costs and all-in sustaining costs related to our Mt Todd project.

We believe that these metrics help investors understand the economics of the Mt Todd project. We present the Non-GAAP financial measures for our Mt Todd project in the tables below. Actual U.S. GAAP results may vary from the amounts disclosed. Other companies may calculate these measures differently.

26

Total Cash Costs and All-In Sustaining Costs

Total Cash Costs, Cash Costs per ounce, and All-in Sustaining Costs per ounce are non-GAAP metrics developed by the World Gold Council to provide transparency into the costs associated with producing gold and provide a comparable standard. The Company reports Cash Costs and AISC per ounce because it believes that these metrics more completely reflect mining costs over the life of a mine. These metrics are widely used in the gold mining industry as a benchmark for performance.

Total Cash Costs consist of operating costs net of power sales, refining costs, and non-government royalties, and exclude depreciation and amortization. The sum of these costs is divided by the corresponding gold ounces estimated to be sold to determine a Cash Cost per ounce amount. The Company’s Total Cash Costs exclude the allocation of corporate general and administrative costs.

All in Sustaining Costs consist of Total Cash Costs (as described above), plus sustaining capital costs. The sum of All-in Sustaining Costs is divided by the corresponding gold ounces estimated to be sold to determine All-in Sustaining Costs per ounce.

Costs excluded from Total Cash Costs and All-in Sustaining Costs are income taxes, government royalties, financing charges, costs related to business combinations, asset acquisitions other than sustaining capital, and asset dispositions.

The following table reconciles the Mt Todd Total Cash Costs, Cash Costs per ounce and AISC per ounce amounts with the project costs described in the 2019 PFS.

	Units	Years 1-5	Life of Mine (13 years)
Payable Gold	koz	2,476	5,305
Operating Costs	US$000s	1,381,396	3,333,631
Refining Cost	US$000s	7,910	17,075
Royalties	US$000s	33,420	71,615
Cash Costs	US$000s	1,422,726	3,422,321
Cash Cost per ounce	US$/oz	$575	$645
Sustaining Capital	US$000s	279,569	536,176
All-In-Sustaining Costs	US$000s	1,702,294	3,958,497
AISC per ounce	US$/oz	$688	$746

ITEM 4.  CONTROLS AND PROCEDURES.

Disclosure Controls and Procedures.

At the end of the period covered by this quarterly report on Form 10-Q for the three months ended September 30, 2019, an evaluation was carried out under the supervision of and with the participation of our management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operations of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act). Based on that evaluation, the CEO and the CFO have concluded that as of the end of the period covered by this quarterly report, our disclosure controls and procedures were effective in ensuring that: (i) information required to be disclosed by us in reports that we file or submit to the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms and (ii) material information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow for accurate and timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during the quarter ended September 30, 2019, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 

27

PART II

ITEM 1.  LEGAL PROCEEDINGS.

We are not aware of any material pending or threatened litigation or of any proceedings known to be contemplated by governmental authorities and/or other parties that are, or would be, likely to have a material adverse effect upon us or our operations, taken as a whole. 

ITEM 1A.  RISK FACTORS.

There have been no material changes from the risk factors set forth in our Annual Report on Form 10-K for the year ended December 31, 2018 as filed with the SEC and Canadian securities regulatory authorities in  February 2019.  

ITEM 2.  UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS.

None.

ITEM 3.  DEFAULTS UPON SENIOR SECURITIES.

None.

ITEM 4.  MINE SAFETY DISCLOSURE.

We consider health, safety and environmental stewardship to be a core value for us.

Pursuant to Section 1503(a) of the United States Dodd-Frank Wall Street Reform and Consumer Protection Act of 2011 (the “Dodd-Frank Act”), issuers that are operators, or that have a subsidiary that is an operator, of a coal or other mine in the United States are required to disclose in their periodic reports filed with the SEC information regarding specified health and safety violations, orders and citations, related assessments and legal actions, and mining-related fatalities under the regulation of the Federal Mine Safety and Health Administration (“MSHA”) under the United States Federal Mine Safety and Health Act of 1977 (the “Mine Act”). During the three months ended September 30, 2019, our U.S exploration properties were not subject to regulation by the MSHA under the Mine Act and consequently no disclosure is required under Section 1503(a) of the Dodd-Frank Act.

ITEM 5. OTHER INFORMATION.

None.

Lease Accounting

Lease Accounting

In February 2016, the FASB issued ASU No. 2016-02, Leases. This new standard established a right-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The Company adopted the standard on January 1, 2019 using the modified retrospective approach. We recognized additional liabilities of $186 on adoption, with corresponding ROU assets of the same amount, based on the present value of the remaining lease payments. Adoption of the standard did not affect lease classification or expense recognition. The Company does not include short term leases in its ROU asset and lease liability calculations. As of September 30, 2019, the ROU asset was $113 and the lease liability was $113, comprised of $97 included in accrued liabilities and other, and $16 in non-current liabilities. The Company’s leases had remaining terms ranging from 0.5 to 2.5 years as of September 30, 2019.

Stock-Based Compensation

Under the Company’s stock option plan (the “Plan”), we may grant options to purchase common shares in the capital of the Company (“Common Shares”) to our directors, officers, employees and consultants. The maximum number of Common Shares that may be reserved for issuance under the Plan, together with all other stock-based compensation arrangements, which include restricted share units (“RSUs”) currently outstanding under the Company’s long term equity incentive plan (“LTIP”) and deferred share units (“DSUs”) issuable pursuant to the Company’s deferred share unit plan (“DSU Plan”), is a variable number equal to 10% of the issued and outstanding Common Shares on a non-diluted basis at any one time. In 2018, the Company issued phantom units to be settled in cash. Options, RSUs, DSUs, and phantom units are granted from time to time at the discretion of the Board of Directors of the Company (the “Board”), with vesting periods and other terms as determined by the Board.

Stock-based compensation expense for the three and nine months ended September 30, 2019 and 2018 is as follows: 

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Stock options	$	29	$	107	$	160	$	307

	$	148	$	271	$	615	$	855
Phantom units	$	28	$	11	$	72	$	11

As of September 30, 2019, unrecognized compensation expense for stock options, RSUs, and phantom units was $88,  $463, and $96, respectively, which is expected to be recognized over weighted average periods of 0.8,  1.3, and 1.3 years, respectively.

Vested, net of shares withheld	(266,296)		0.84
Unvested - September 30, 2019	1,493,301	$	0.51

A portion of the RSU awards vest on a fixed future date provided the recipient continues to be affiliated with Vista on that date. Other RSU awards vest subject to certain performance and market criteria, including the accomplishment of certain corporate objectives and the Company’s share price performance. The minimum vesting period for RSUs is one year.  

During the nine months ended September 30, 2019 and 2018, the Company withheld Common Shares with an equivalent value to meet the employee withholding tax obligations which resulted from RSUs that vested in the period. Common Shares withheld are considered cancelled/forfeited. 

Deferred Share Units

In May 2019, the Company’s shareholders approved the DSU Plan. The DSU Plan provides for granting of DSUs to non-employee directors. DSUs vest immediately, however the Company will issue one Common Share for each DSU only after the non-employee director has ceased to be a director of the Company. Additionally, in May 2019, the Company’s shareholders approved an amendment to the LTIP such that non-employee directors are excluded from future grants under the LTIP. At the time the DSU Plan was approved, the Board granted 366,000 DSUs and the Company recognized $209 in DSU expense.

The following table summarizes the DSUs outstanding as of September 30, 2019:

		Weighted average
	Number of	grant-date fair
	DSUs	value per DSU

Granted	366,000	0.57
Outstanding - September 30, 2019	366,000	0.57

Phantom Units

In 2018, the Company granted a total of 265,000 phantom units to certain employees. The value of each unit is equal to the Company’s share price on the vesting date and is payable in cash. The phantom units vest on fixed future dates provided the recipient continues to be affiliated with Vista on those dates. The Company accounts for these units as awards classified as liabilities with $14 included in current liabilities as of September 30, 2019. The Company recognized $28 and $72 of compensation expense for these phantom units in the three and nine months ended September 30, 2019, respectively.

Lease Accounting

In February 2016, the FASB issued ASU No. 2016-02, Leases. This new standard established a right-of-use (“ROU”) model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The Company adopted the standard on January 1, 2019 using the modified retrospective approach. We recognized additional liabilities of $186 on adoption, with corresponding ROU assets of the same amount, based on the present value of the remaining lease payments. Adoption of the standard did not affect lease classification or expense recognition. The Company does not include short term leases in its ROU asset and lease liability calculations. As of September 30, 2019, the ROU asset was $113 and the lease liability was $113, comprised of $97 included in accrued liabilities and other, and $16 in non-current liabilities. The Company’s leases had remaining terms ranging from 0.5 to 2.5 years as of September 30, 2019.

8. Fair Value Accounting

The following table sets forth the Company’s assets measured at fair value by level within the fair value hierarchy. As required by accounting guidance, assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. 

	Fair value at September 30, 2019
	Total		Level 1		Level 3
Other investments (Midas Gold Shares)	$	3,511	$	3,511	$	—

	Fair value at December 31, 2018

Other investments (Midas Gold Shares)	$	5,462	$	5,462	$	—
Used mill equipment (non-recurring)	$	5,500	$	—	$	5,500

Our investment in Midas Gold Shares is classified as Level 1 of the fair value hierarchy as it is valued at quoted market prices in an active market.

The used mill equipment is classified as Level 3 of the fair value hierarchy as its value at December 31, 2018 was based on an independent third-party valuation. As of September 30, 2019, management had not identified sufficient changes in conditions to require an update to the independent third-party evaluation. The mill equipment is included in plant and equipment on the Condensed Consolidated Balance Sheets for each period presented. There have been no transfers between levels in 2019, nor have there been any changes in valuation techniques.

Mt Todd, Australia	$	2,146	$	2,146
Guadalupe de los Reyes, Mexico		—		275
	$	2,146	$	2,421

During October 2017, we entered into an agreement (the “Option Agreement”) to option our interest in the Guadalupe de los Reyes gold and silver project in Sinaloa, Mexico (“Los Reyes”) to Minera Alamos Inc. and its subsidiary Minera Alamos de Sonora S.A. de C.V. (“Minera Alamos”). In June 2019, the Option Agreement was assigned from Minera Alamos to ePower Metals Inc. by way of assignment agreement (the “Assignment Agreement”), with our consent. ePower Metals Inc. subsequently changed its name to Prime Mining Corporation (“Prime Mining”). The Assignment Agreement provides that in certain circumstances, the rights under the Option Agreement will revert from Prime Mining to Minera Alamos.

Pursuant to the terms of the Option Agreement and the Assignment Agreement, we granted Minera Alamos or Prime Mining, as applicable, (the “Optionholder”) an exclusive right and option right to earn a 100% interest in the Los Reyes project by:

· making payments totaling $6,000, comprised of a payment of $1,500 made at the execution of the Option Agreement (the “Option Grant Date”); two successive payments of $1,500 each to be made at the one-year and two-year anniversaries of the Option Grant Date; and a final $1,500 payment to be made before the four-year anniversary of the Option Grant Date;

· maintaining the concessions comprising the Los Reyes project in good standing;

· fulfilling all obligations to the Ejido La Tasajera (the “Ejido”) as set out in the temporary occupation contract between us and the Ejido;

· granting us a capped net smelter return royalty (“NSR”) on production from open pit mining (the “Open Pit NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz) up to an aggregate of $2,000 in royalty payments;

· granting us a perpetual NSR on production from underground mining (the “Underground NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz); and

· granting us the right to assume a 49% non-carried interest in an underground project if the Optionholder decides to develop an underground mine at the Los Reyes project (the “Back-in Right”).

The Option Agreement provides that all cash payments are non-refundable and optional to the Optionholder, and in the event the Optionholder fails to pay any of the required amounts as set out in the Option Agreement, or fails to comply with its other obligations, the Option Agreement will terminate and the Optionholder will have no interest in the Los Reyes project. Provided it is not in breach of the Option Agreement, the Optionholder may, at its discretion, accelerate the above payment schedule. 

Subject to the Optionholder timely making all the option payments, and fulfilling its other obligations with respect to the Option Agreement, we will transfer 100% of the shares of the Company’s 100% owned subsidiary Minera Gold Stake S.A. de C.V., the entity which owns the Los Reyes project, to the Optionholder and the Open-Pit NSR and Underground NSR will be granted to us.

If the Optionholder discovers and decides to develop an underground mine at the Los Reyes project and we exercise the Back-in Right, we and the Optionholder have agreed to form a joint venture to develop and operate the underground mine. If the joint venture is formed, the Underground NSR will terminate.

In October 2018, the Company agreed to extend the due date for the second $1,500 option payment under the Los Reyes Option Agreement by six months to April 23, 2019, at which time the payment was made. As consideration for the deferral, the Company received an additional $150 in cash, $50 paid on October 24, 2018 and $100 paid on January 23, 2019. In addition, Minera Alamos paid interest of $67 at a rate of 1.5% per month on the unpaid balance of the $1,500 payment beginning January 24, 2019.

The Company has determined that control of the Los Reyes project has not been transferred for accounting purposes. Therefore, the first option payment of $1,500 received in October 2017 and the $150 for extension of the second option payment were accounted for as a reduction to carrying value. Receipt of the second option payment of $1,500 and interest of $67 during April 2019 reduced the carrying value to zero and resulted in recognition of $1,392 as a deferred option gain. The third Los Reyes project option payment of $1,500 was received from Prime Mining in October 2019. This receipt will be recorded as additional deferred option gain. In addition, potential royalty revenue and future option payments have not been recognized for accounting purposes.

1. Nature of Operations and Basis of Presentation

Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) operate in the gold mining industry. We are focused on evaluation, acquisition, exploration and advancement of gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements with other mining companies, or outright sales of assets for cash and/or other consideration. We undertake programs designed to improve the value of our gold projects through exploration drilling and/or technical studies focused on optimizing previous engineering work. 

The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) in Northern Territory, Australia. Mt Todd is the largest undeveloped gold project in Australia. In January 2018, the Company received authorization for the last major environmental permit for Mt Todd. In September 2019, Vista announced the positive results of an updated preliminary feasibility study (the “2019 PFS”) for Mt Todd. Process improvements reflected in the 2019 PFS have resulted in improved estimated gold recovery and increased estimated gold production at Mt Todd.

As of September 30, 2019, the Company also holds 7.8 million common shares of Midas Gold Corp. (“Midas Gold Shares”), a non-core project in Mexico subject to a third-party option agreement, and royalty interests in the United States and Indonesia.
