[10-Q] VISTA GOLD CORP Quarterly Earnings Report

Rhea-AI Filing Summary

Vista Gold (VGZ) reported Q3 2025 results, posting a net loss of $723 thousand while ending the quarter with cash and cash equivalents of $13,717 thousand and working capital of $12,787 thousand. The company had no debt. Other income of $1,248 thousand reflected a tax recovery related to a prior asset sale.

Vista continued to advance its 100%-owned Mt Todd project in Australia. The 2025 feasibility study outlines a 15,000 tpd operation with average annual gold production of 153,000 ounces during years 1–15 and 146,000 ounces over a 30-year mine life. Reported costs include Cash Costs of $1,399/oz during years 1–15 and AISC of $1,449/oz (life-of-mine AISC $1,499/oz). Initial capital is $425 million, with an after-tax NPV5% of $1,060 million and capital efficiency of $93/oz.

During Q3, Vista raised $1,391 thousand via its at-the-market program (nine months: $2,212 thousand). Shares outstanding were 126,209,108 as of November 5, 2025. The company also notes a 2025 court ruling in Mexico in favor of its subsidiary regarding 2012 tax matters and ongoing stewardship and permitting activities at Mt Todd.

Insights

Mining equity analyst

Q3 shows stable liquidity; Mt Todd FS outlines 30-year plan.

Vista Gold closed Q3 with $13,717,000 in cash and no debt, offsetting a quarterly net loss of $723,000. Financing remained light, with ATM net proceeds of $1,391,000 in the quarter and $2,212,000 year-to-date. Other income benefited from a $1,248,000 tax recovery.

The 2025 Mt Todd feasibility study describes a 15,000 tpd operation producing 153 koz/year in years 1–15 and 146 koz/year over a 30-year life. Reported AISC is $1,449/oz (years 1–15) and $1,499/oz life-of-mine, with initial capital of $425,000,000 and after-tax NPV5% of $1,060,000,000. These metrics frame potential project economics under the disclosed assumptions.

Key dependencies include continued access to liquidity, execution of site programs, and future decisions on funding pathways. Subsequent filings may detail updates to permitting and project expenditures as the company advances Mt Todd.

VISTA GOLD CORP.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Dollar amounts in U.S. dollars and in thousands, except share-related amounts)

​

1. Overview 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. The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) in Northern Territory, Australia. Since acquiring Mt Todd in 2006, we have invested substantial financial resources to systematically explore, evaluate, engineer, permit, and de-risk the Project.

​

The interim Condensed Consolidated Financial Statements (“interim statements”) of the Company are unaudited. In the opinion of management, all adjustments, reclassifications, and disclosures necessary for a fair presentation of these interim statements are 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, 2024 as filed with the United States Securities and Exchange Commission and Canadian securities regulatory authorities on Form 10-K (“2024 Financial Statements”). The balance sheet as of December 31, 2024 as presented herein was derived from the Company’s 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. Certain prior period amounts presented were reclassified within the operating income (expense) section of the Unaudited Condensed Consolidated Statements of Income/(Loss) to conform with the current period presentation.

​

These interim statements have been prepared on the going concern basis of accounting, which contemplates Vista having the ability to meet its obligations when due in the normal course of business for the foreseeable future. Because the Company does not have recurring cash inflows from operations or investments, we rely on other sources of financing to fund operations. Such funding sources may include sales of non-core assets, equity issuances, royalty or stream agreements, convertible instruments, and debt facilities. Although management estimates the Company has access to sufficient cash flows for the next twelve months, there can be no assurance that the Company will be able to obtain adequate funding, or that such funding will be on terms acceptable to the Company, to meet future operational needs which may result in delays, reductions, or discontinuations of ongoing programs.

​

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

2. Significant Accounting Policies

Significant accounting policies are included in the 2024 Financial Statements.

​

​

​

3. Mineral Properties

​

Mt Todd, Northern Territory, Australia

​

The capitalized mineral property values are as follows:

​	​	​	​	​	​	​	​
​		At September 30, 2025			At December 31, 2024		​
Mt Todd, Australia	​	$	1,070	​	$	920	​
​	​	​	​	​	​	​	​

​

Vista acquired Mt Todd in March 2006. The purchase price and related transaction costs of $2,146 were capitalized as mineral properties. Since 2006, the Company has systematically advanced the Project through exploration, metallurgical testing, engineering, environmental/operational permitting activities, and ongoing site management activities. Prior to 2024, costs associated with these and other related activities were charged to expense as incurred.

​

Mineral resource development costs are capitalized for an ore body where proven and probable reserves exist, and the activities are directed at obtaining additional information about the ore body or converting measured, indicated, and inferred resources to proven and probable reserves. All other property-related costs are expensed as incurred. Capitalized

​

Table of Contents

mineral property development costs totaled $nil and $150 in the three and nine months ended September 30, 2025, respectively. Capitalized mineral property development drilling costs totaled $475 and $1,503 in the three and nine months ended September 30, 2024, respectively. The Company derecognized $3,091 of mineral property costs, inclusive of $945 of capitalized development drilling costs, in June 2024 upon recognition of the gain on grant of a royalty interest in Mt Todd, see Note 6. See Note 8 for a discussion of commitments and contingencies associated with Mt Todd.

​

6. Gain on Grant of Royalty

​

On December 13, 2023, Vista Gold Australia Pty. Ltd. (“Vista Gold Australia”), a wholly owned subsidiary of the Company, entered into a royalty agreement with Wheaton Precious Metals (Cayman) Co., an affiliate of Wheaton Precious Metals Corp. (“Wheaton”), in relation to Mt Todd (the “Royalty Agreement”).

​

Pursuant to the terms of the Royalty Agreement, Wheaton provided Vista with $20,000 cash in three instalments to advance Mt Todd and for general corporate purposes, excluding direct expenditures for any project other than Mt Todd, in exchange for payments of a portion of the gross revenue from Mt Todd, (the “Royalty”). Upon receipt of the final instalment in June 2024, the Company recognized a gain on grant of royalty interest in mineral titles of $16,909. The gain comprised previous instalment payments totaling $10,000 and the $10,000 received for the final instalment, net of the associated mineral property carrying value as of the date the final instalment was received.

​

The Royalty is at a rate of 1% of gross revenue from the Project if the completion objectives for the Project are achieved by April 1, 2028. Beginning April 1, 2028, if the completion objectives for the Project are not achieved, the Royalty shall increase annually at a rate of up to 0.13% to a maximum Royalty rate of 2%. Any annual increases beginning April 1, 2028 shall be reduced on a pro rata basis to the extent that Mt Todd has initiated operations but has yet to achieve a completion test at an average daily processing rate of 15,000 tonnes per day. The Royalty rate, the annual increase percentage, and maximum Royalty rate can each be reduced by one-third upon the occurrence of one of the following events: (i) a change of control of Vista Gold Australia occurs prior to April 1, 2028 and Vista Gold Australia provides timely notice and payment to Wheaton of certain amounts; or (ii) payment to Wheaton of the applicable Royalty associated with Vista Gold Australia delivering 3.47 million gold ounces to a third party. The Royalty is payable on production from both the Mt Todd mining and exploration licenses. Wheaton has also been granted a right of first refusal on future royalties, streams or pre-pays pertaining to Mt Todd.

A security interest was granted by Vista Gold Australia to Wheaton. The security includes, among other things, a mortgage over the Mt Todd tenements and a collateralized interest in the assets, rights and interests of Vista Gold Australia.

​

7. Common Shares

​

Equity Financing

​

Vista is party to an at-the-market offering agreement (the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”), under which the Company has the right, but is not obligated, to issue and sell Common Shares in the capital of the Company (each a “Common Share”) through Wainwright (the “ATM Program”). The ATM Agreement was refreshed in November 2024 to allow for aggregate sales proceeds of up to $8,000.

​

During the three and nine months ended September 30, 2025, the Company realized net proceeds of $1,391 and $2,212, respectively, under the ATM Program. During the three and nine months ended September 30, 2024, the Company realized net proceeds of $395 and $639, respectively, under the ATM Program. As of September 30, 2025, $5,512 remained available under the ATM Program.

​

Stock-Based Compensation

​

The Company’s active stock-based compensation plans include restricted share units (“RSUs”) issuable pursuant to the Company’s long-term equity incentive plan and deferred share units (“DSUs”) issuable pursuant to the Company’s deferred share unit plan (“DSU Plan”). The Company's stock option plan remains in place; however, no new issuances can be made at this time. Stock-based compensation may be issued to our directors, officers, employees, and consultants. The maximum number of Common Shares that may be reserved for issuance under the combined stock-based compensation plans is a variable number equal to 10% of the issued and outstanding Common Shares on a non-diluted basis at any particular time. Stock-based compensation may be granted from time to time at the discretion of the Board of Directors of the Company (the “Board”), with vesting provisions as determined by the Board.

​

During the nine months ended September 30, 2025 and 2024, the Company withheld Common Shares with an equivalent value to meet employee withholding tax obligations of $268 and $85, respectively, which resulted from the vesting of RSUs during these periods.

​

Deferred Share Units

​

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 when the non-employee director ceases to be a director of the Company. During the nine months ended September 30, 2025, the Board granted 364,000 DSUs and the Company recognized $251 in DSU expense. During the nine months ended September 30, 2024, the Board granted 767,000 DSUs and the Company recognized $293 in DSU expense.

​

All potentially dilutive Common Shares were considered antidilutive because the Company was in a net loss position for the three and nine months ended September 30, 2025 and the three months ended September 30, 2024.

​

Unvested RSUs representing 100,668 Common Shares, stock options to purchase 400,000 Common Shares, and warrants to purchase 7,408,101 Common Shares were excluded from the computation of diluted earnings per share for the nine months ended September 30, 2024 because their effect would have been antidilutive.

​

8. Commitments and Contingencies

​

The Mt Todd site was not reclaimed by the predecessor owners when the mine closed in 2000. Reclamation obligations associated with the period before Vista’s purchase of Mt Todd are presently the responsibility of the Government of the Northern Territory, Australia (the “NT Government”). Vista may, but is not obligated to, give notice to the NT Government that it wishes to commence mining activities at Mt Todd. As a result of any such notice by the Company, the NT Government will transfer to Vista a) certain assets upon terms and conditions to be agreed or determined by an independent valuer and b) the historical rehabilitation liabilities that are presently the responsibility of the NT Government. The historical rehabilitation liabilities to be transferred to Vista are currently stated by the NT Government at approximately A$73 million.

​

Under agreements with the Jawoyn Association Aboriginal Corporation with respect to Mt Todd, we have agreed to a gross proceeds royalty (“GPR”) ranging between 0.125% and 2.0%, depending on prevailing gold prices and foreign exchange rates, and a 1.0% GPR not tied to gold price or foreign exchange rates. The combined GPR ranges from 1.125% to 3.0%.

​

Mt Todd is also subject to the Royalty Agreement with Wheaton; see Note 6.

​

Our exploration and development activities are subject to various laws and regulations governing the protection of the environment and our interactions with community stakeholders, among others. These laws and regulations are continually changing and are generally becoming more restrictive. Future expenditures that may be required for compliance with these laws and regulations cannot be predicted at this time. If the Company determines that it is probable that an obligation exists and the amount can be reasonably estimated, a provision would be recorded. This may include costs associated with actions by the Company and actions attributable to others should no other responsible or potentially responsible parties be identified. We conduct our operations in a manner designed to minimize effects on stakeholders and the environment.

In August 2024, an assessment was issued by the Mexican tax authorities, known as the Servicio de Administración Tributaria (“SAT”), to the Company’s Mexican subsidiary, Minera Gold Stake (“MGS”). The assessment disallowed the tax basis of certain mineral properties that was established by MGS in 2012 and subsequently utilized to offset taxable income in subsequent years and other deductions taken in 2012 that the SAT concluded should have been deducted over multiple years. In response, MGS filed suit in the Tax Court in the State of Mexico in October 2024. In September 2025, the court ruled in favor of MGS in its suit brought against the SAT on these 2012 matters and there is no remaining legal remedy available to the SAT against the court’s decision. While there remains a SAT case associated with MGS’s utilization in 2020 of the 2012 deductions, management believes that the September 2025 ruling provides for recognition of the deductions utilized to offset 2020 taxable income related to the sale of MGS. However, the outcome of this remaining case is unknown and no estimate of potential loss can be made at this time.

​

In May 2025, penalties totaling A$162,000 were assessed under the Northern Territory Aboriginal Sacred Sites Act 1989 and paid by Vista. The penalties resulted from drilling undertaken by Vista in 2021 and 2022.

​

9. Segment Information

​

The Company has one reportable segment: Australia. The Australia segment conducts exploration, development, and care and maintenance activities at Vista’s principal asset, the Mt Todd gold project in Northern Territory, Australia. This segment does not presently report any revenues from operations. Through the Australia segment, the Company seeks to position Mt Todd as a development opportunity within the gold sector. The Company’s chief operating decision maker is the Chief Executive Officer (“CODM”). The CODM uses consolidated net income/loss as the measure of segment profit and loss to assess performance and allocate resources.

​

We reported no revenues during the three and nine months ended September 30, 2025 and 2024. The geographic location of mineral properties and plant and equipment is provided in Notes 3 and 4, 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, 2025, and the related notes thereto, which have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). 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 are in U.S. dollars in thousands, except per share amounts, commodity prices, and currency exchange rates unless specified otherwise.

​

Overview

​

Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) operate as a development-stage company in the gold mining industry. Vista does not currently generate cash flows from mining operations.

​

Our flagship asset is the Mt Todd Gold Project (“Mt Todd” or the “Project”), a development-stage gold deposit located in the Tier-1 mining jurisdiction of Northern Territory, Australia (the “NT”). Mt Todd offers a large gold mineral reserve, development optionality, expansion opportunities, exploration upside, advanced local infrastructure, community support, and demonstrated economic feasibility.

​

On July 29, 2025, the Company announced the results of a new Mt Todd feasibility study focused on developing a 15,000 tonnes per day (“tpd”), or 5.3 million tonnes per annum (“tpa”), operation (the “2025 FS” or the “Study”). The 2025 FS significantly decreased the initial capital, prioritized grade over tonnes, delivered stable gold production over the extended life of the project, and provided a fresh perspective for developing the Project using design and operating practices commonly employed by Australian gold operations.

​

The 2025 FS marks a significant shift in the strategy for Mt Todd, demonstrating the potential for near-term development of a smaller, lower capital cost project than previously evaluated. The Study incorporates the use of contract mining, third-party power generation, and other design and operating practices to reduce operational risks. The 2025 FS demonstrates the opportunity for Mt Todd to deliver attractive economic returns with stable gold production over a 30-year mine life. The Study does not assume any expansion of the planned mining/processing rate, but the 15,000 tpd design layout provides ample space for future expansion of the processing plant.

​

Feasibility Study Highlights

​

●Average annual gold production of 153,000 ounces during years 1-15 and 146,000 over the 30-year life of mine

● Average ore grade of 1.04 grams gold per tonne (“g Au/t”) over the first 15 years of operations and 0.97 g Au/t over the life of mine

● Life of mine average gold recovery of 88.5% from 3-stage crush, single-stage sort, 2-stage grind, and carbon-in-leach (“CIL”) recovery circuit

● After-tax NPV_5% of $1.1 billion, internal rate of return of 27.8%, and 2.7 year payback at a $2,500 per ounce gold price

● After-tax free cash flow at a $2,500 per ounce gold price of $1.6 billion for first 15 years of commercial operations

● Initial capital requirements of $425 million, a 59% reduction from the 2024 FS (as defined below)

-Capital Efficiency: $93 per ounce (initial capital : total ounces of gold produced)

- Benefit to Cost Ratio of 2.5 (NPV_5% : initial capital)

● All-in Sustaining Cost (“AISC”) of $1,449 per ounce during years 1-15 and $1,499 per ounce during years 1-30

A technical report summary titled “S-K 1300 Technical Report Summary – Mt Todd Gold Project – 15 ktpd Feasibility Study – Northern Territory, Australia” with an effective date of July 29, 2025 and a filing date of September 11, 2025 (the “S-K 1300 Report”) for the 2025 FS was prepared in accordance with Item 1300 of Regulation S-K (“S-K 1300”) under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”) and filed on EDGAR at www.sec.gov on September 11, 2025.

​

A companion technical report titled “NI 43-101 Technical Report, Mt Todd Gold Project, 15 ktpd Feasibility Study, Northen Territory Australia” with an effective date of July 29, 2025 (the “NI 43-101 Report”) for Canadian purposes was prepared in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and filed on SEDAR+ at www.sedarplus.ca on September 11, 2025. The NI 43-101 Report is referenced herein for informational purposes only. The Mineral Resources and Mineral Reserves for the NI 43-101 Report are the same as the Mineral Resources and Mineral Reserves for the S-K1300 Report.

​

The Company previously completed a feasibility study for Mt Todd in 2022, with material project costs and economic returns updated in 2024 (the “2024 FS”). This study evaluated the development of a 50,000 tpd, nominally 17.75 million tpa, operation.

​

The Company continues to prioritize the efficient use of financial resources to advance Mt Todd. Our funding strategy is to maintain adequate liquidity while minimizing share dilution as we seek to preserve, enhance, and realize value from Mt Todd. The Company periodically raises funds in the capital markets and considers alternative strategies and possible corporate opportunities as ways to enhance its liquidity and deliver shareholder value.

Results from Operations

​

Summary

​

Cash totaled $13,717 and working capital was $12,787 at September 30, 2025. See “Liquidity and Capital Resources”. The Company had no debt as of September 30, 2025.

​

Consolidated net loss for the three months ended September 30, 2025 and 2024 was $723 and $1,638, or $0.01 and $0.01 per basic share, respectively. Consolidated net income (loss) for the nine months ended September 30, 2025 and 2024 was ($5,787) and $12,922, or ($0.05) and $0.11 per basic share, respectively. The principal components of the period-over-period changes are discussed below.

​

16

Table of Contents

Operating income and expenses

​

Gain on Grant of Royalty Interest in Mineral Titles

​

The Company recognized a gain on grant of royalty interest in mineral titles of $16,909 in June 2024. The gain comprises the previously deferred gain on instalment payments totaling $10,000 and the gain on $10,000 received for the final instalment, net of the associated mineral property carrying value of $3,091 as of the date the final instalment was received.

​

Exploration, property evaluation and holding costs

​

Exploration, property evaluation and holding costs were $1,237 and $1,081 for the three months ended September 30, 2025 and 2024, respectively; and $4,559 and $2,462 for the nine months ended September 30, 2025 and 2024, respectively.  In addition to recurring site activities in each year, the Company carried out a development drilling program during 2024 and completed the 2025 FS in 2025. The variances in the three- and nine-month periods resulted largely from capitalization of the drilling program in 2024, whereas the feasibility study work was expensed in 2025.

​

Corporate administration

​

Corporate administration costs were $846 and $738 during the three months ended September 30, 2025 and 2024; and $2,822 and $2,773 for the nine months ended September 30, 2025 and 2024, respectively. Expenses in the comparable three- and nine-month periods were higher because of a modest increase in corporate activities and year-over-year cost increases.

​

Gain on sale of plant and equipment

​

In March 2024, the Company recorded a gain of $802 upon sale of certain components of our used mill equipment. Gross proceeds totaled $900 and were offset by selling expense of $98.

​

Non-operating income and expenses

​

Interest income

​

Interest income was $134 and $230 for the three months ended September 30, 2025 and 2024, respectively; and $443 and $496 for the nine months ended September 30, 2025 and 2024, respectively. The decrease in the comparable three-month period was due to a decrease in the average interest rate applicable to invested cash balances and a lower average cash balance. The decrease in the comparable nine-month period was due to a decrease in the average interest rate applicable to invested cash balances.

​

Other income (expense)

​

Other income (expense) was $1,248 and ($35) for the three months ended September 30, 2025 and 2024, respectively; and $1,218 and ($10) for the nine months ended September 30, 2025 and 2024, respectively. The increase in the comparable three and nine-month periods was due to the receipt of $1,257 related to our recovery of certain tax amounts paid in connection with the 2020 sale of the Los Reyes gold project in Mexico.

​

Financial Position, Liquidity and Capital Resources

​

Operating activities

​

Net cash used in operating activities was $4,641 and $3,808 for the nine months ended September 30, 2025 and 2024, respectively. The increase in operating cash outflows largely resulted from 2025 expenditures for the 2025 FS being expensed while costs of the 2024 drilling program were recorded as capitalized development costs and included in investing activities, partially offset by sources of cash resulting from changes in working capital.

​

17

Table of Contents

Investing activities

​

Net cash provided by (used in) investing activities was ($536) and $16,139 for the nine months ended September 30, 2025 and 2024, respectively. Cash provided by investing activities was higher in 2024 because the Company received Royalty Agreement proceeds totaling $17,000 and net proceeds from the sale of certain used mill equipment of $802. Cash used in investing activities was lower by $1,353 in 2025 because substantially all 2024 drilling costs were capitalized as development costs while the 2025 FS costs were expenses and included as cash used in operating activities. Cash used in investing activities for purchases of plant and equipment was higher by $226 in 2025 due to installation of an enhanced evaporation system.

​

Financing activities

​

During the nine months ended September 30, 2025 and 2024, net cash of $1,944 and $554, respectively, was provided by financing activities. Cash provided by financing activities during the nine months ended September 30, 2025 was $2,212 of net proceeds under the ATM Program (as defined below) offset by payments of $268 for employee withholding taxes in lieu of issuing common shares of the Company (“Common Shares”) earned from the vesting of restricted share unit awards. Cash provided by financing activities during the nine months ended September 30, 2024 was $639 of net proceeds under the ATM Program offset by payments of $85 for employee withholding taxes in lieu of issuing Common Shares earned from the vesting of restricted share unit awards.

​

Liquidity and capital resources

​

The Company considers available cash, cash equivalents, and any short-term investments to be its primary measure of liquidity. Our cash liquidity position as of September 30, 2025 and December 31, 2024, included cash and cash equivalents was $13,717 and $16,950, respectively. This represents a net decrease of $3,233 during the nine months ended September 30, 2025.

​

Current assets, net of current liabilities (“Working Capital”), is a secondary measure of liquidity for the Company. The Company had Working Capital of $12,787 and $16,457 at September 30, 2025 and December 31, 2024, respectively. This represents a net decrease of $3,670 during the nine months ended September 30, 2025.

​

During the nine months ended September 30, 2025, the Company’s primary sources of cash inflows were $2,212 from equity financing activity, receipt of $1,257 related to our recovery of certain tax amounts paid previously, and interest income of $443. These sources of cash were offset by operating cash outflows of $6,341 and other expenditures of $804. Recurring costs for corporate administration and Mt Todd maintenance, and spending on the 2025 FS and other project programs comprise most of the Company’s operating cash outflows during the nine months ended September 30, 2025. Of the other expenditures, $386 related to additions of plant and equipment and $150 related to Vista’s mineral resources development activities at Mt Todd. Additional details regarding financial results for the nine months ended September 30, 2025 are presented in the “Results from Operations” section above and the preceding narratives in this section regarding operating activities, investing activities, and financing activities.

​

For the 12-month period following September 30, 2025, the Company estimates net recurring expenditures will be approximately $7,400, plus $2,000 of non-recurring project program costs related to upcoming metallurgical evaluations; final payments for the 2025 FS and enhanced water evaporation equipment; permit modifications; and ongoing Mt Todd site maintenance costs. Management expects to fund Vista’s activities during the next twelve months from existing Working Capital. Equity financing may also be utilized to supplement the Company’s Working Capital.

​

Vista is a party to an at-the-market offering agreement (the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”) to provide balance sheet flexibility at a potentially lower cost than other means of equity issuances. Under the ATM Agreement, the Company can, but is not obligated to, issue and sell Common Shares through Wainwright for aggregate gross proceeds of up to $8,000 (the “ATM Program”). During the nine months ended September 30, 2025, the Company issued 1,783,388 Common Shares under the ATM Program for net proceeds of $2,212. As of September 30, 2025, $5,512 remained available under the ATM Program.

​

18

Table of Contents

Offers and sales of Common Shares under the ATM Program were and will be made only in the United States in an “at the market offering” as defined in Rule 415 under the United States Securities Act of 1933, as amended, subject to an effective registration statement under the U.S. Securities Act of 1933, as amended, and no offers or sales of Common Shares under the ATM Agreement will be made in Canada. The Common Shares were and will be distributed at market prices prevailing at the time of sale.

​

Other potential sources of cash inflows may include other equity issuances not covered by the ATM Program, monetization of Vista’s remaining non-core assets, which include three royalty interests on properties in the U.S. and Canada, and used mill equipment that is being marketed by a third-party mining equipment dealer.

​

We believe our Working Capital as of September 30, 2025, together with other potential future sources of financing and sales of non-core assets, will be sufficient to fund our currently planned net corporate expenses, Mt Todd holding costs, and other anticipated Mt Todd programs for at least one year from the date of issuance of this quarterly report on Form 10-Q. Should the Company modify its plans, additional equity issuances or other forms of financing will be required to meet Working Capital requirements.

​

Vista’s long-term viability depends upon our ability to realize value from our principal asset, Mt Todd. We seek to maintain adequate liquidity and minimize share dilution as we advance our primary objective to maximize returns to our shareholders by preserving, enhancing, and realizing value from Mt Todd. Our funding strategy is to maintain a low expenditure profile, realize value from our remaining non-core assets and, when considered appropriate, issue additional equity or utilize other means of financing that support our value realization objectives. Vista also considers possible corporate opportunities to enhance liquidity. The underlying value and recoverability of the amounts shown as mineral properties and plant and equipment as presented in our Condensed Consolidated Balance Sheets depend on market and industry conditions, our ability to attract sufficient capital resources to execute our strategy, and the ultimate success of our programs to enhance and realize value at Mt Todd.

​

Off-Balance Sheet Arrangements

​

We have no off-balance sheet arrangements.

Contractual Obligations

​

We have no material contractual obligations as of September 30, 2025.

​

Non-U.S. GAAP Financial Measures

​

In this report, we have provided information prepared or calculated according to U.S. GAAP, as well as provided certain non-U.S. GAAP prospective financial performance measures. Because the non-U.S. GAAP performance measures do not have standardized meanings 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 non-U.S. 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-U.S. GAAP measures presented in this report are not, and are not intended to be, presentations in accordance with U.S. GAAP. These metrics represent financial measures related to the Project.

​

19

Table of Contents

We believe that these metrics help investors understand the economics of the Project as presented in the Mt Todd FS. We present the non-U.S. GAAP financial measures for our Project in the tables below. Presentation based on U.S. GAAP may cause results to vary from the amounts disclosed in this report. Other companies may calculate these measures differently.

​

Determination of Non-U.S. GAAP Financial Measures

​

This report may include the following financial measures presented on a non-U.S. GAAP basis:

● Cash Costs per ounce produced;

● AISC per ounce;

● Capital Efficiency; and

● Benefit to Cost Ratio.

​

Cash Costs per ounce of gold produced and AISC per ounce of gold produced are non-U.S. GAAP metrics developed by the World Gold Council intended to improve transparency into the costs associated with producing gold and provide a standard for comparison across the industry. The Company reports Cash Costs and AISC on a per ounce basis and Cash Costs on a per tonne processed basis because we believe these metrics appropriately reflect mining costs over specified periods and the life of mine. The Company reports on Capital Efficiency and Benefit to Cost Ratio because these metrics provide a standard measurement of initial capital efficiency. Similar metrics are used in the gold mining industry as comparative benchmarks of performance.

​

Cash Costs consist of Project operating costs, refining costs, the Jawoyn Royalty, and the Wheaton Royalty. The sum of these costs is divided by the corresponding ounces of gold produced or tonnes processed to determine Cash Cost per ounce or per tonne processed metrics, respectively.

​

AISC consists of Cash Costs (as described above), plus sustaining capital costs. The sum of these costs is divided by the corresponding ounces of gold produced to determine the AISC per ounce metric.

​

Costs excluded from Cash Costs and AISC include depreciation and amortization, exploration and development costs not required to achieve the gold production set out in the technical study, corporate costs or allocations, income taxes, NT Government royalties subject to legislative changes, financing charges, costs related to business combinations, asset acquisitions other than sustaining capital, and asset dispositions.

​

Capital Efficiency consists of initial capital expenditures divided by the ounces of gold produced.

​

Benefit to Cost Ratio consists of the after-tax NPV_5% of project cash flows divided by initial capital.

Certain U.S. Federal Income Tax Considerations 

Vista believes it is possible the Company may be classified as 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, 2024, 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.”

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.
