**PART I**

**ITEM 1. BUSINESS.** 

*In this annual report on Form 10-K, unless the context otherwise requires, the terms "we", "us", "our", "Vista", "Vista Gold", or the "Company" refer to Vista Gold Corp. and its subsidiaries. References to AUD or A$ refer to Australian currency and USD or $ refer to United States currency, all in thousands, unless specified otherwise, except per share-related, per tonne, and per ounce amounts.* 

**Overview**

Vista Gold Corp. and its subsidiaries 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 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 "Mt Todd FS" or the "Study"). The Mt Todd FS significantly decreased the initial capital requirement, 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 Mt Todd 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 Mt Todd 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

&nbsp;&nbsp;&nbsp;&nbsp;● 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

&nbsp;&nbsp;&nbsp;&nbsp;● 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

&nbsp;&nbsp;&nbsp;&nbsp;● After-tax NPV <sub>5%</sub> of $1.1 billion, internal rate of return of 27.8%, and 2.7-year payback at a $2,500 per ounce gold price

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

&nbsp;&nbsp;&nbsp;&nbsp;● 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)<sup>(3)</sup>

Benefit to Cost Ratio of 2.5 (NPV<sub>5%</sub> : initial capital) <sup>(3)</sup>

&nbsp;&nbsp;&nbsp;&nbsp;● All-in Sustaining Cost ("AISC") of $1,449 per ounce during years 1-15 and $1,499 per ounce during years 1-30 <sup>(3)</sup>

*Notes to investors:* 

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Proven and Probable Mineral Reserves are estimated in accordance with S-K 1300 (as defined below).* 

&nbsp;&nbsp;&nbsp;&nbsp;*(2)* *See "Item 1. Business – Cautionary Note to Investors Regarding Estimates of Measured, Indicated and Inferred Resources and Proven and Probable Mineral Reserves" for additional information.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(3)* *Capital efficiency, benefit to cost ratio, and AISC per ounce are non-U.S. GAAP financial measures; see "Non-U.S. GAAP Financial Measures" for additional disclosure.*

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 Mt Todd 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"). The 2024 FS evaluated the development of a 50,000 tpd, nominally 17.75 million tpa, operation.

In January 2026, the Company announced continued progress at its Mt Todd gold project and outlined the pathway to initiate detailed engineering and design in 2027. The Company would expect this milestone to initiate a period of approximately 27-months for design, construction, and commissioning.

Our focus for 2026 is on establishing the foundation for the successful execution of the Mt Todd project. Priorities include obtaining permit modifications to align existing approved permits with the Mt Todd FS; expanding corporate capability by building an Australia-based team to lead project development; and addressing recommendations presented in the Mt Todd FS that will provide key inputs for detailed engineering and design. On March 9, 2026, Vista closed a public offering for aggregate gross proceeds totaling $44,850 to fund these priorities and other general corporate purposes.

We have commenced efforts to obtain permit modifications and are actively engaged with consultants, regulators, and stakeholders. Some modifications have already been submitted, and programs to support other submissions have been planned and are expected to begin within the coming weeks. We anticipate the approval of these modifications will be achieved in 2027.

We are addressing recommendations presented in the Mt Todd FS. Recent drilling has provided core for selective metallurgical testing to confirm grind size, gold recoveries, and optimal selection and sizing of equipment in the process plant. A geotechnical review is also underway, with planned drilling around the Batman pit to assess the opportunity to steepen the west pit wall, reduce stripping, and potentially convert additional mineral resources to mineral reserves.

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.

Vista was originally incorporated on November 28, 1983 under the name "Granges Exploration Ltd." It amalgamated with Pecos Resources Ltd. during June 1985 and continued as Granges Exploration Ltd. In June 1989, Granges Exploration Ltd. changed its name to Granges Inc. Granges Inc. amalgamated with Hycroft Resources & Development Corporation during May 1995 and continued as Granges Inc. Effective November 1996, Da Capo Resources Ltd. and Granges, Inc. amalgamated under the name "Vista Gold Corp." and, effective December 1997, Vista continued from the Province of British Columbia to the Yukon Territory, Canada under the *Business Corporations Act* (Yukon Territory). On June 11, 2013, Vista continued from the Yukon Territory, Canada to the Province of British Columbia, Canada under the *Business Corporations Act* (British Columbia).

**Human Capital Management**

As of December 31, 2025, we had 13 full-time employees and one part-time employee globally. In addition, we use consultants with specific skills to assist with various aspects of our corporate affairs, project evaluation, due diligence, corporate governance and property management. Since December 31, 2025, we have added four Australian employees and expect to add additional Australian employees throughout 2026.

The health and safety of our employees, contractors, and the communities in which we operate are high priorities in the way we manage our business. Oversight is provided by the Company's board of directors (the "Board of Directors") and the Board of Directors' Health, Safety, Environment and Social Responsibility Committee. Management utilizes the principles set out in our Health & Safety Policy to administer health and safety programs. Employees and others entering our workplaces are provided with and required to use personal protective equipment appropriate for their duties. Each employee and visitor to our workplaces receives relevant orientation and is required to adhere to our established site health and safety protocols. In addition, we comply with relevant policies and regulations enacted by regulatory agencies in the jurisdictions where we operate. Our compensation programs include consideration of health and safety performance in determining incentive awards.

It is Vista's priority to maintain a culture of ethical performance as a core value, as reflected in the Company's Code of Business Conduct and Ethics and other related policies. Oversight is provided by the Board of Directors and, for specific areas of performance, by committees of the Board of Directors. Periodically, our employees are required to review the Code of Business Conduct and Ethics and acknowledge their understanding of the content and intent to comply. Our compensation programs include consideration of ethical performance in determining incentive awards.

Vista values the diversity and talents of its team, collectively working together in an inclusive environment to achieve corporate goals and personal professional development objectives. We cultivate a culture that is sensitive to the importance of diversity and inclusion in the workplace.

Our compensation programs are designed to align compensation of our employees with Vista's corporate objectives and performance, and are designed to provide proper incentives to attract, retain and motivate employees to achieve superior results. The structure of our compensation programs balances competitive wages, benefits and incentive earnings for both short-term and long-term performance.

**Environmental, Social, and Governance Responsibility**

Vista is committed to implementing and continuing to improve business practices that are designed to minimize environmental impacts of our operating activities, support the people and communities within our areas of influence, and appropriately manage the business affairs of our organization. We believe part of being a good corporate citizen requires a dedicated focus on how we affect the environment and fulfill our responsibilities to stakeholders. We have worked closely with governmental entities in the NT and local groups, including the Jawoyn Association Aboriginal Corporation (the "Jawoyn Association"), as we strive towards an environmentally sound and socially responsible development plan.

**Segment Information**

We have one reportable segment, consisting of acquisition, exploration and evaluation activities which are focused on Australia. We reported no mining operating revenues during the years ended December 31, 2025 and 2024. Additional segment-level disclosure is provided in Note 11 – Segment Information. Geographic location of mineral properties and plant and equipment is provided in Note 3 – Mineral Properties and Note 4 – Plant and Equipment to our Consolidated Financial Statements under the section heading "Item 8. Financial Statements and Supplementary Data" below.

[**Table of Contents**](#Toc)

**Reclamation**

The Mt Todd site was not reclaimed by the predecessor owners when the mine closed in 2000. Reclamation obligations associated with this period and prior to Vista's acquisition in 2006 are presently the responsibility of the NT Government. At such time as we provide notice to the NT Government that we intend to proceed with development, the Company will then assume these historical rehabilitation liabilities, currently stated by the NT Government at A$73 million. As a result, we would be required to mitigate long-term environmental impacts, including any of those existing prior to 2006, that are not otherwise mitigated during the life of mine, by stabilizing, contouring, re-sloping and re-vegetating various portions of the Project after mining and mineral processing operations are completed. Reclamation programs would be conducted in accordance with detailed plans, which would be finalized and reviewed by the appropriate regulatory agencies prior to initiating such programs.

**Government Regulation**

Our exploration and development activities and other property interests are subject to various national, state, territorial, provincial, and local laws and regulations in Australia and other jurisdictions, which govern prospecting, development, mining, mine safety, production, exports, taxes, labor standards, occupational health, waste disposal, protection of the environment, the use and disposal of hazardous substances, and other matters. We have obtained the major authorizations based on a 50,000 tpd technical report from 2018, and we have authorizations currently required to conduct our exploration, site management, and other programs. We believe we comply in all material respects with applicable mining, health, safety and environmental statutes and regulations in all the jurisdictions in which we operate.

*Key Australian Environmental and Social Laws* 

Mineral projects in the NT are subject to Australian federal and NT laws and regulations regarding environmental matters and the use and disposal of hazardous wastes and materials. As with all mining projects, development and operation of Mt Todd is expected to have a variety of environmental and social impacts. We are required under Australian laws and regulations (federal and territorial) to acquire permits and other authorizations before Mt Todd can be developed and mined. In September 2014, the environmental impact statement ("EIS") for Mt Todd was approved. The Environmental Protection Agency of the Northern Territory Government ("NT EPA") advised that it had assessed the environmental impacts of the proposed gold mine at Mt Todd and authorized the Company to proceed with development, subject to the recommendations as outlined in the assessment report (the "Assessment Report"). The Assessment Report included a request for Vista to secure an authorization under the federal Environmental Protection and Biodiversity Conservation Act 1999 ("EPBC") as it relates to the Gouldian Finch. In January 2018, the authorization required by the EPBC was approved by the Australia Department of the Environment and Energy. We must comply with the terms of our Authority Certificates under the Northern Territory Aboriginal Sacred Sites Act 1989 which deals with the handling of archeological material and sacred sites. We are also subject to statutory requirements under the NT Mining Management Act, which includes the requirement to have a mining authorization before the start of mining operations. The mining authorization is issued after the approval of the mining license. It is the legal document that makes the mining license and any additional conditions binding for the Project. The Mt Todd Mining Management Plan ("MMP") and associated mining authorization were approved by the Northern Territory Department of Industry, Tourism and Trade in June 2021. As a result of recent changes to the Mining Management Act, all MMPs were converted to Deemed Environmental (Mining) Licenses ("DEML") in July 2024, and companies have four years to convert the DEMLs to Environmental (Mining) Licenses ("EML"). In the interim period, the DEML provides the same rights and obligations in regard to the operating plans for Mt Todd as determined in the MMP. The Company is in the process of aligning the relevant approvals and authorizations discussed in this section with the plans and designs in the Mt Todd FS.

**Environmental Regulation**

Mt Todd is subject to various federal, territorial, and local laws and regulations governing protection of the environment. Such laws and regulations are continually changing and, in general, are becoming more restrictive. Our policy is to conduct business in a way that safeguards public health and the environment. We believe that our operations are conducted in material compliance with applicable laws and regulations.

[**Table of Contents**](#Toc)

Changes to current local, territorial, or federal laws and regulations in the jurisdictions where we have exploration and development activities could require additional capital expenditures and increase operating and/or reclamation costs. We are unable to predict what additional legislation, if any, might be proposed or enacted, or what additional regulatory requirements could impact the economics of Mt Todd.

During 2025, Mt Todd did not have any material non-compliance occurrences with any applicable environmental laws and regulations. See "Item 1. Business – Reclamation", above.

**Competition**

We compete with other mining companies to acquire, explore, finance, and develop gold properties and to retain expert consultants required to complete our geological and project development studies. We also compete with other mining companies to hire mining engineers, geologists and other skilled personnel in the mining industry, and for exploration and development services. Some of these competing mining companies have substantially greater financial and technical resources than Vista. As a result, we may have difficulty acquiring attractive gold projects at reasonable prices, engaging skilled consultants with sufficient resources to support timely completion of work programs, and attracting and retaining qualified personnel.

**Gold Price History**

The price of gold is volatile and is affected by numerous factors, all of which are beyond our control, such as the sale or purchase of gold by various central banks and financial institutions, inflation, recession, fluctuation in the relative values of the U.S. dollar to foreign currencies, changes in global gold supply and demand, and political and economic conditions.

The following table presents the high, low and average London Fix prices in U.S. dollars per troy ounce of gold over the past five years and during 2026 through March 4, 2026:

**Glossary of Selected Mining Terms**

"*bedding*" means the characteristic structure of sedimentary rock in which layers of different composition, grain size or arrangement are layered one on top of another in a sequence with oldest on the bottom and youngest at the top.

"*comminution*" means the process in which ore is broken into small fragments by crushing, grinding, and other processes.

"*conglomerate*" refers to clastic sedimentary rock that contains rounded particles that are greater than two millimeters in diameter. The space between the pebbles is generally filled with smaller particles and/or a chemical cement that binds the rock together.

"*cut-off grade*" means the grade (i.e., the concentration of metal or mineral in rock) that determines the destination of the material during mining. For purposes of establishing prospects of economic extraction, the cut-off grade is the grade that distinguishes material deemed to have no economic value from material deemed to have economic value.

"*deposit*" is an informal term for an accumulation of mineralized material.

"*development stage issuer*" is an issuer that is engaged in the preparation of mineral reserves for extraction on at least one material property.

"*development stage property*" is a property that has mineral reserves disclosed, pursuant to S-K 1300, but no material extraction.

"*feasibility study*" is a comprehensive technical and economic study of the selected development option for a mineral project that includes appropriately detailed assessments of realistically assumed mining, processing, metallurgical, economic, marketing, legal, environmental, social and governmental considerations together with any other relevant operational factors and detailed financial analysis that are necessary to demonstrate at the time of reporting that extraction is reasonably justified or economically viable. The results of a feasibility study may reasonably serve as the basis for a final decision by a proponent or financial institution to proceed with, or finance, the development of a project. The confidence level of a feasibility study is higher than that of a preliminary feasibility study, initial assessment, or scoping study.

"*g Au/t*" means grams of gold per tonne.

"*geosyncline*" means a major trough or downwarp of the Earth's crust, in which great thicknesses of sedimentary and/or volcanic rocks have accumulated.

"*indicated mineral resource*" and "*indicated resource*" mean "indicated mineral resource" defined by S-K 1300 as that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of

[**Table of Contents**](#Toc)

confidence of a measured mineral resource, an indicated mineral resource may be converted only to a probable mineral reserve.

"*inferred mineral resource*" and "*inferred resource*" mean "inferred mineral resource" defined by S-K 1300 as that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve.

"*measured mineral resource*" and "*measured resource*" mean "measured mineral resource" defined by S-K 1300 as that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

"*ktpd*" means thousands of tonnes per day.

"*Mineral Reserve*" is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted.

"*Mineral Resource*" is a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.

"*ore*" means material containing minerals in such quantity, grade and chemical composition that they can be economically extracted.

"*ore sorting*" means technology that separates "ore" and "waste" based on physical and/or chemical properties of the material being sorted.

"*oxide*" means mineralized rock in which some of the original minerals have been oxidized (*i.e.*, combined with oxygen). Oxidation tends to make the rock more porous and permits a more complete permeation of cyanide solutions so that minute particles of gold in the interior of the minerals will be more readily dissolved.

*"oz"* or *"ounce"* means troy ounce and is equivalent to 31.10348 grams.

"*probable mineral reserves*" under S-K 1300 is the economically mineable part of an indicated and, in some cases, a measured mineral resource.

"*proven mineral reserves*" under S-K 1300 is the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource.

"*qualified person" or "QP"* as defined under S-K 1300 (as defined below) is an individual who is: (1) a mineral industry professional with at least five years of relevant experience in the type of mineralization and type of deposit under consideration and in the specific type of activity that person is undertaking on behalf of the registrant; and (2) an eligible

[**Table of Contents**](#Toc)

member or licensee in good standing of a recognized professional organization at the time the technical report is prepared. For an organization to be a recognized professional organization, it must: (i) be either: (A) an organization recognized within the mining industry as a reputable professional association; or (B) a board authorized by U.S. federal, state or foreign statute to regulate professionals in the mining, geoscience or related field; (ii) admit eligible members primarily on the basis of their academic qualifications and experience; (iii) establish and require compliance with professional standards of competence and ethics; (iv) require or encourage continuing professional development; (v) have and apply disciplinary powers, including the power to suspend or expel a member regardless of where the member practices or resides; and (vi) provide a public list of members in good standing.

"*qualified person*" or "*QP*" as defined under NI 43-101 means an individual who (1) is an engineer or geoscientist with a university degree, or equivalent accreditation, in an area of geoscience, or engineering, relating to mineral exploration or mining; (2) has at least five years of experience in mineral exploration, mine development or operation, or mineral project assessment or any combination of these that is relevant to his or her professional degree or area of practice; (3) has experience relevant to the subject matter of the mineral project and the technical report; (4) is in good standing with a professional association; and (5) in the case of a professional association in a foreign jurisdiction, has a membership designation that (i) requires attainment of a position of responsibility in their profession that requires the exercise of independent judgment; and (ii) requires (A) a favorable, confidential peer evaluation of the individual's character, professional judgment, expertise and ethical fitness; or (B) a recommendation for membership by at least two peers, and demonstrated prominence or expertise in the field of mineral exploration or mining. Note: a professional association is a self-regulatory organization of engineers, geoscientists or both that, among other criteria, requires compliance with the professional standards of competence and ethics established by the organization and has disciplinary powers over its members.

"*recovery*" means that portion of the metal contained in the ore that is successfully extracted by processing and is expressed as a percentage.

"*sampling*" means selecting a fractional, but representative, part of a mineral deposit for analysis.

"*strike*" when used as a noun, means the direction, course or bearing of a vein or rock formation measured on a level surface and, when used as a verb, means to take such direction, course or bearing.

"*sulfide*" means a compound of sulfur and some other element. From a metallurgical perspective, sulfide rock is primary rock that has not been oxidized. Both ore and waste may contain sulfide minerals.

"*tpa*" means tonnes per annum.

"*tpd*" means tonnes per day.

"*vein*" means a fissure, fault or crack in a rock filled by minerals that have traveled upwards from some deep source.

"*waste*" means rock lacking sufficient grade and/or other characteristics of ore.

**Cautionary Note to Investors Regarding Estimates of Measured, Indicated and Inferred Resources and Proven and Probable Mineral Reserves**

We are subject to the reporting requirements of the Exchange Act and applicable Canadian securities laws. As a result, we report our mineral resources and mineral reserves according to two different standards. For U.S. purposes, mineral property disclosures are reported in accordance with S-K 1300 under the Exchange Act, while Canadian disclosures are reported in accordance with 43-101. Both sets of reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but the standards embody slightly different approaches and definitions.

In our public filings in the U.S. and Canada and in certain other announcements not filed with the U.S. Securities Exchange Commission ("SEC"), we disclose proven and probable reserves and measured, indicated, and inferred resources, each as defined in S-K 1300 and NI 43-101. As currently reported, there are no material differences in our disclosed proven and

[**Table of Contents**](#Toc)

probable reserves and measured, indicated, and inferred resource under each of S-K 1300 and NI 43-101. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves; therefore, investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into S-K 1300-compliant or NI 43-101-compliant reserves. Estimations of inferred resources involve far greater uncertainty as to their existence and economic viability than the estimations of other categories of resources; therefore, it cannot be assumed that all or any part of inferred resources will ever be upgraded to a higher category. Investors are cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically.

**ITEM 1A. RISK FACTORS.**

An investment in our securities involves a high degree of risk. The risks described below are not the only ones facing the Company or otherwise associated with an investment in our securities. Additional risks not presently known to us or which we currently consider not material may also adversely affect our business. If any of the following risks actually occur, our business, financial condition, and operating results could be materially adversely affected.

**Operating Risks**

***We cannot be assured that the Mt Todd FS has, or future studies will, accurately forecast economic results.***

Mt Todd is our principal asset. Our ability to arrange financing to develop Mt Todd and our future profitability depend on the economic and technical feasibility of the Project as established through formal feasibility studies, such as the Mt Todd FS. There can be no assurance that the mining, comminution, gold recovery processes, gold production rates, revenue, and capital and operating costs including taxes and royalties will not vary unfavorably from the estimates and assumptions included in the Mt Todd FS, or any future studies.

[**Table of Contents**](#Toc)

***Mt Todd requires substantial capital investment, and we may be unable to raise sufficient capital on favorable terms or at all.***

Ongoing site costs, construction, operation and reclamation of Mt Todd will require significant capital. Our ability to raise sufficient capital and/or secure a development partner or other form of transaction on satisfactory terms, if at all, will depend on several factors, including the Mt Todd FS or any future studies, applicable laws and regulations, acquisition of the requisite permits, macroeconomic conditions, and future gold prices. Uncontrollable factors or other factors such as lower gold prices, unanticipated operating or permitting challenges, inability to secure a development partner or other form of transaction, actual and perceived environmental impacts, or illiquidity in the debt or equity markets, including the cost of capital and other conditions of financing arrangements that impose restrictive covenants and security interests that may affect the Company's ability to operate as intended and ultimately its ability to continue as a going concern, could impede our ability to finance ongoing and future activities at Mt Todd on acceptable terms, or at all.

***If we decide to construct the mine at Mt Todd, we will assume substantial reclamation obligations resulting in a material financial obligation.***

The Mt Todd site was not reclaimed when the original mine closed. Although we are not currently responsible for the reclamation of these historical disturbances, we will accept full responsibility for them if and when we make a decision to finance and construct the mine and provide notice to the NT Government of our intention to take over and assume the management, operation and rehabilitation of Mt Todd. At such time, we will be required to provide a bond or other surety in a form and amount satisfactory to the NT Government that would cover the estimated cost to reclaim the Mt Todd property. In addition, the regulatory authorities may increase reclamation and bonding requirements from time to time. The satisfaction of these bonding requirements and continuing or future reclamation obligations will require a significant amount of capital. There is no assurance that we will be able to provide an acceptable form of bond or other surety, or provide sufficient working capital to complete any required rehabilitation, if and when such obligations are assumed by the Company.

***There may be delays in the construction of Mt Todd.***

Delays in commencing and completing construction could result from factors such as availability and performance of engineering and construction contractors, suppliers, consultants, and employees; availability of required equipment; delays in receiving any required approvals and authorizations; and availability of capital. Any delay in performance by any one or more of the contractors, suppliers, consultants, employees or other persons on which we depend, or lack of availability of required equipment, or delay or failure to receive required governmental approvals or financing could delay, prevent commencement of, or interrupt construction at Mt Todd. There can be no assurance of whether or when construction at Mt Todd will start, the duration of the construction period, or that the necessary personnel, equipment, supplies, or other resources will be available to the Company if and when construction is started.

***Increased costs could impede our ability to become profitable.***

Capital and operating costs at mining operations are subject to variation due to a number of factors, such as changing ore grade, changing metallurgy, and revisions to mine plans in response to changing commodity prices, additional drilling results and updated geologic interpretations. In addition, costs are and may be affected by the cost of capital, tax and royalty regimes, other royalties, trade tariffs, the global cost of mining and processing equipment, commodity prices, and foreign exchange rates, as well as the costs of fuel, electricity, operating supplies, and appropriately skilled labor. These costs are at times subject to volatile price movements, including increases that could make future development and production at Mt Todd less profitable or uneconomic. This could have a material adverse effect on our business prospects, results of operations, cash flows and financial condition.

***We cannot be assured that we will have an adequate water supply for mining operations at Mt Todd.***

Water at Mt Todd is expected to be provided from a freshwater reservoir that is fed by seasonal rainfall. Insufficient rainfall, or drought-like conditions in the catchment area for the reservoir could limit or extinguish this water supply. Sufficient water resources may not be available, resulting in curtailment or stoppage of operations until the water supply

[**Table of Contents**](#Toc)

is replenished. This could have a material adverse effect on our business prospects, results of operations, cash flows and financial condition.

***We rely on third parties to fulfill their obligations under agreements.***

Our business strategy includes entering into agreements with third parties ("Third Parties"). Such Third Parties may: (i) have economic or business interests or goals that are inconsistent with or opposed to ours; (ii) have rights in conflict with what we believe to be in our best interests; (iii) take action contrary to our policies or objectives; or (iv) as a result of financial or other reasons, be unable or unwilling to fulfill their obligations under the agreement(s). Any one or a combination of these could result in liabilities for us and/or could adversely affect the value of the related project(s) and, by association, damage our reputation and consequently our ability to acquire or advance other projects and/or attract future Third Parties.

***Our exploration and development interests are subject to evolving environmental regulations.***

Our property and royalty interests are subject to environmental regulations. Environmental legislation is becoming more restrictive, with stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects, and a heightened degree of responsibility for companies and their officers, directors, and employees. There is no assurance that future changes in environmental laws and regulations will not adversely affect our interests. Currently, our property and royalty interests are subject to environmental laws and regulations in Australia and the U.S.

***We could be subject to environmental lawsuits.***

Neighboring landowners and other third parties could file claims based on environmental statutes and common law for personal injury and property damage allegedly caused by environmental nuisance or the release of hazardous substances or other waste material into the environment on or around our properties. There can be no assurance that our defense of such claims would be successful. This could have a material adverse effect on our business prospects, results of operation, cash flows, financial condition, and corporate reputation.

***We may have material undisclosed environmental liabilities of which we are not aware.***

We have been engaged in gold exploration since 1983. Since inception, the Company has been involved in numerous exploration projects in many jurisdictions. There may be environmental liabilities associated with disturbances at these projects for which the Company may be identified as a responsible or potentially responsible party, regardless of its level of involvement in creating the related disturbance. We may not be aware of such claims against the Company until regulators provide notice thereof. Consequently, we may have material undisclosed environmental responsibilities which could negatively affect our business prospects, results of operations, cash flows, financial condition, and corporate reputation.

***There may be challenges to our title to mineral properties and rights of use.***

There may be challenges to our title to our mineral properties and rights of use. If there are title defects or challenges to our rights to use such titles as intended with respect to any of our properties, we may be required to compensate other persons or reduce or lose our interest in the affected property. In any such case, the investigation and resolution of title issues could divert Company resources from our core strategies.

***Opposition to Mt Todd could have a material adverse effect.***

There is generally an increasing level of public concern relating to extractive industries. Opposition to extractive industries, or our development and operating plans at Mt Todd specifically, could have adverse effects on our reputation and support from other stakeholders. As a result, we may be unable to secure adequate financing or complete other activities necessary to continue our planned activities. Any resulting delays or an inability to develop and operate Mt Todd as planned could

[**Table of Contents**](#Toc)

have a material adverse effect on our business prospects, results of operations, cash flows, financial condition and corporate reputation.

***Our exploration and development activities, strategic transactions, or any acquisition activities may not be commercially successful and could fail to lead to gold production or fail to add value*.**

Substantial expenditures are required to acquire gold properties, establish mineral reserves through drilling and analysis, develop metallurgical processes to extract metal from the ore and develop the mining and processing facilities and infrastructure at any site chosen for mining. We cannot be assured that any such activities will be commercially successful, be completed in a timely manner, lead to gold production, or add value.

**Financial and Business Risks**

***We have a history of losses, and we do not expect to generate earnings from operations or pay dividends in the near term, if at all.***

We are a development stage issuer, and we devote our efforts to our development stage property, Mt Todd. We do not currently produce gold and do not currently generate operating earnings from gold production. We finance our business activities principally by issuing equity.

We have incurred losses in all annual periods since 1998, except for the years ended December 31, 2011, during which we recorded non-cash net gains, December 31, 2015 during which we recorded gains related to research and development refunds, December 31, 2020 during which we monetized certain mineral property interests, and December 31, 2024 when we recognized a gain associated with the grant of a royalty interest in mineral titles. We expect to continue to incur losses. We have no history of paying cash dividends and we do not expect to be able to pay cash dividends or to make any similar distribution of cash or other assets in the foreseeable future, if at all.

***We depend on key personnel, the loss of which could have a material adverse effect on our business.***

We are dependent on the services of key management personnel. The loss of any of these key personnel, if not replaced, could have a material adverse effect on our business and operations. Our future success will depend in part on our ability to identify, attract, engage, train, and retain highly qualified personnel. Competition for these individuals is intense, and we may not succeed in identifying, attracting, or retaining qualified personnel. The loss or interruption of the services of any of our executive officers or other key employees, the inability to identify, attract, or retain qualified personnel in the future, the inability to successfully implement executive officer, key employee or other personnel transitions, or delays in hiring qualified personnel could make it difficult for us to conduct and manage our business and meet key objectives, which could harm our business, financial condition, and operating results. The loss of services from key personnel or a limitation in their availability could materially and adversely impact our business, prospects, liquidity, financial condition and results of operations. Further, such a loss could be negatively perceived in the capital markets.

***A substantial or extended decline in gold prices would have a material adverse effect on the value of our assets and on our ability to raise capital and could result in lower than estimated economic returns.***

The value of our assets, our ability to raise capital and our future economic returns are substantially dependent on the price of gold. The gold price is volatile and is affected by numerous factors beyond our control. Factors tending to influence gold prices include:

● gold sales or leasing by governments and central banks or changes in their monetary policy, including gold inventory management and reallocation of reserves;

● speculative short or long positions on futures markets;

● the relative strength of the U.S. dollar;

● current, or expectations of future, rates of inflation or interest rates;

● changes to economic conditions in the United States, China, India and other industrialized or developing countries;

[**Table of Contents**](#Toc)

● geopolitical conflicts;

● changes in jewelry, investment, or industrial demand;

● changes in supply from production, disinvestment, and scrap; and

● forward sales by producers in hedging or similar transactions.

A substantial or extended decline in the gold price could:

● negatively impact our ability to raise capital on favorable terms, or at all;

● negatively affect our ability to find a partner, investor, or lender for the development of Mt Todd;

● jeopardize the development of Mt Todd;

● reduce our existing estimated mineral resources and reserves by removing material from these estimates that could not be economically processed at lower gold prices;

● reduce the potential for future revenues from gold projects in which we have an interest;

● reduce funds available to operate our business; and

● reduce the market value of the Common Shares and our assets.

***Industry consolidation could result in the acquisition of a control position in the Company for less than fair value.***

Consolidation within the industry is a growing trend. As a result of the broad range of market and industry factors including the price of gold, we believe the current market value of the Common Shares does not reflect the fair value of the Company's assets. These conditions could result in the acquisition of a control position, or attempted acquisition of a control position in the Company at what we believe to be less than fair value. This could result in substantial costs to us and divert management's attention and resources. A completed acquisition could result in realized losses for shareholders of the Company.

***We expect to need additional financing in connection with the implementation of our business and strategic plans from time to time.***

The exploration, construction, development and acquisition of mineral properties and the ongoing operation of our facilities requires a substantial amount of capital and may depend on our ability to obtain financing. We may accordingly need additional capital in order to take advantage of further opportunities. Our financial condition, general market conditions, volatile gold markets, volatile interest rates, a significant disruption to our business or operations, or other factors may make it difficult to secure financing. Continued volatility in equity markets, specifically including energy and commodity markets, may increase the costs associated with equity financings and may create the potential need for us to offer higher discounts and other value (e.g., warrants).

***We may be unable to raise additional capital on favorable terms, or at all.***

Our exploration and, if warranted, development activities and the construction and start-up of any mining operation require substantial amounts of capital. To develop Mt Todd, acquire attractive gold or other projects, and/or continue our business, we will have to secure a development partner or otherwise source sufficient equity, debt or other forms of capital, raise additional funds from the sale of non-core assets and / or seek additional sources of capital from other external sources. There can be no assurance that we will be successful in securing a development partner or otherwise raising additional capital on acceptable terms, including the cost of such capital and other conditions of financing arrangements that impose restrictive covenants and security interests that may affect the Company's ability to operate as intended and ultimately its ability to continue as a going concern. If we cannot raise sufficient additional capital, we may be required to substantially reduce or cease operations, any of which may affect our ability to continue as a going concern.

***We face intense competition in the mining industry.***

The mining industry is intensely competitive in all its phases. Some of our competitors are much larger, established companies with greater financial and technical resources than ours. We compete with other companies for attractive mining properties, for capital, for equipment and supplies, for outside services, and for qualified managerial and technical

[**Table of Contents**](#Toc)

employees. Access to financing, equipment, supplies, skilled labor, and other resources may also be affected by competition from non-mining related commercial sectors. If we are unable to raise sufficient capital, we will be unable to execute exploration and development programs, or such programs may be reduced in scope. Competition for equipment and supplies could result in shortages of necessary supplies and/or increased costs. Competition for outside services could result in increased costs, reduced quality of service and/or delays in completing services. If we cannot successfully retain or attract qualified employees, our ability to advance the development of Mt Todd, to attract necessary financing, to meet all our environmental and regulatory responsibilities, or to take opportunities to improve our business, could be negatively affected. This could have a material adverse effect on our business prospects, results of operations, cash flows and financial condition.

***The occurrence of events for which we are not insured may affect our cash flow and overall profitability.***

We maintain insurance policies that mitigate certain risks related to our assets and business activities. This insurance is maintained in amounts that we believe to be reasonable based on the circumstances surrounding each identified risk. However, we may elect to limit or not maintain insurance for certain risks because of the high premiums associated with insuring those risks in relation to potential perils or for various other reasons. In other cases, insurance may not be available for certain risks. We do not insure against political risk. The occurrence of events for which we are not insured adequately, or at all, could result in significant losses that could materially adversely affect our financial condition and our ability to fund our business.

***Currency fluctuations may adversely affect our costs.***

Our material property interests are in Australia. Most costs in Australia are incurred in the local currency. Appreciation of the Australian dollar, if any, against the U.S. dollar effectively increases our cost of doing business. This could have the effect of increasing the amount of capital and operating costs required to continue to maintain, explore and develop Mt Todd, reducing the pace at which it is explored and developed, and/or cause activities to be suspended either temporarily or permanently.

***The Company believes it is possibly a "passive foreign investment company," which would likely have adverse U.S. federal income tax consequences for U.S. shareholders.***

U.S. shareholders of our Common Shares should be aware that the Company believes it is possible we may be classified as a passive foreign investment company ("PFIC") up to and including the taxable year ended December 31, 2025, and based on current business plans and financial projections, management believes there is a possibility that the Company could be classified as a PFIC during the current taxable year. If the Company is classified as a PFIC for any year during a U.S. shareholder's holding period, then such U.S. shareholder generally will be required to treat any gain realized upon a disposition of Common Shares, or any so-called "excess distribution" received on their Common Shares, as ordinary income, and to pay an interest charge on a portion of such gain or distributions, unless the shareholder makes a timely and effective "qualified electing fund" ("QEF Election") or a "mark-to-market" election with respect to the Common Shares. A U.S. shareholder who makes a QEF Election generally must report on a current basis its share of the net capital gain and ordinary earnings for any year in which the Company is PFIC, whether or not the Company distributes any amounts to its shareholders. U.S. shareholders should be aware that there can be no assurance that the Company will satisfy record keeping requirements that apply to a QEF Election, or that the Company will supply U.S. shareholders with information that such U.S. shareholders require to report under the QEF Election rules, in event that the Company is a PFIC and a U.S. shareholder wishes to make a QEF Election. Thus, U.S. shareholders may not be able to make a QEF Election with respect to their Common Shares. A U.S. shareholder who makes the mark-to-market election generally must include as ordinary income each year the excess of the fair market value of the Common Shares over the taxpayer's basis therein. This paragraph is qualified in its entirety by the discussion below in "Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities - Certain U.S. Federal Income Tax Considerations for U.S. Residents." Each U.S. shareholder should consult his or her own tax advisor regarding the U.S. federal, U.S. state and local, and foreign tax consequences of the PFIC rules and the acquisition, ownership, and disposition of Common Shares.

***Certain directors and officers may serve as directors and officers of other companies in the natural resources sector.***

[**Table of Contents**](#Toc)

While there are no known existing or potential conflicts of interest between Vista and any of its directors or officers, certain of the directors and officers do or may serve as directors and officers of other natural resource companies and therefore it is possible that a conflict may arise between their duties as a director or officer of our Company and their duties as a director or officer of such other companies. Our directors and officers are aware of the existence of laws governing accountability of directors and officers for corporate opportunity and disclosure of conflicts of interest. Should any director or officer breach the duties imposed upon them by applicable laws, such actions or inactions could have a material adverse effect on our business prospects, results of operations, cash flows, financial position, and corporate reputation.

**Industry Risks**

***Calculations of mineral resources and mineral reserves are estimates only and subject to uncertainty.***

Estimation of mineral resources and mineral reserves is an imprecise process and the accuracy of such estimates is a function of the quantity and quality of available data, assumptions used, and judgments made in interpreting geological information and estimating future capital and operating costs. There is significant uncertainty in mineral resources and mineral reserves estimates, and the economic results of mining a mineral deposit may differ materially from the estimates as additional data develops, interpretations change, or actual economic conditions vary from the estimates used.

***Estimated mineral resources and mineral reserves may be materially affected by other factors.***

In addition to uncertainties inherent in estimating mineral resources and mineral reserves, other factors may adversely affect estimated mineral resources and mineral reserves. Such factors may include but are not limited to metallurgical, environmental, permitting, legal, title, taxation, socio-economic, marketing, political, gold prices, and capital and operating costs. Any of these or other adverse factors may reduce or eliminate estimated mineral reserves and mineral resources and could have a material adverse effect on our business prospects, results of operations, cash flows, financial position, and corporate reputation.

***Feasibility studies and other technical studies are estimates only and subject to uncertainty.***

Feasibility studies, such as our Mt Todd FS and other technical studies are used to estimate the economic viability of an ore deposit, as are preliminary feasibility studies, preliminary economic assessments, and scoping studies. Feasibility studies are the most detailed studies and reflect higher levels of confidence in estimated production rates, and capital and operating costs. Accepted levels of confidence required to meet the standards set out in S-K 1300 are plus or minus 15% for feasibility studies, plus or minus 25-30% for preliminary feasibility studies and plus or minus 35-40% for preliminary economic assessments. Confidence levels for scoping studies may vary, but generally provide less confidence than preliminary economic assessments. These thresholds reflect the levels of confidence that exist at the time the study is completed. Subsequent changes to metal prices, foreign exchange rates, reclamation requirements, operating and capital costs, and other variables may cause actual results of economic viability to differ materially from these estimates. Results of any subsequent Mt Todd feasibility study may be less favorable than the Mt Todd FS.

***Mining companies are increasingly required to consider and provide benefits to the communities, regions, and countries in which they operate, and are subject to extensive environmental, health and safety laws and regulations.***

As a result of public concern about the real or perceived detrimental effects of economic globalization, global climate impacts, and other adverse environmental effects resulting from the operation of extractive industries, businesses in general and the mining industry in particular face increasing public scrutiny of their activities. These businesses are under pressure to demonstrate that as they seek to generate satisfactory returns on investment to shareholders, other stakeholders including employees, governments, Aboriginal peoples, communities surrounding operations, adjacent regions, and the countries in which they operate, such constituencies benefit and will continue to benefit from their commercial activities. The potential consequences of these pressures include reputational damage, delays, suspension of activities, legal claims, increased costs, increased social investment obligations, difficulty in acquiring permits, and increased taxes and royalties payable to governments and communities.

[**Table of Contents**](#Toc)

***Mining exploration, development and operating activities are inherently hazardous.***

Mineral exploration and development involve many risks that even a combination of experience, knowledge and careful evaluation may not be able to overcome. Projects and operations in which we have direct or indirect interests will be subject to all the hazards and risks normally incidental to exploration, development, and production of gold and other metals, any of which could result in work stoppages, damage to property, physical harm, and possible environmental damage. The nature of these risks is such that liabilities might exceed any liability insurance policy limits. It is also possible that the liabilities and hazards might not be insurable, we could elect not to be insured against such liabilities due to high premium costs or other reasons, or our insurance for a particular event or circumstance might be insufficient, in which event we could incur significant costs that could have a material adverse effect on our business prospects, results of operations, cash flows, financial position, and corporate reputation.

***Pending or future legislation and regulations or other standards intended to address climate change could result in increased operating costs.***

Gold production is energy intensive, resulting in a significant carbon footprint. A number of governments, governmental bodies, the World Bank and/or other entities maintain, have introduced, or are contemplating laws, regulations and standards in response to potential impacts of climate change. This type of legislation and possible future legislation and increased regulation regarding climate change could impose significant costs related to increased energy requirements, capital equipment, environmental monitoring and reporting and other costs to comply with such regulations.

***Pending or future initiatives involving taxation could result in increased taxes and operating costs.***

There is growing attention from the media and the public to perceived international tax avoidance techniques which could result in escalating rates of poverty, inequality and unemployment in host countries. Initiatives like the Base Erosion and Profit Shifting project led by the Organization for Economic Cooperation and Development and specific country legislative measures, including Australia, aim to reform the system of international taxation to minimize international tax avoidance techniques. This initiative and possible future initiatives could result in increased tax expenses and related compliance costs for Mt Todd or other future mining operations.

**Securities Risks**

***Our share price may be volatile and your investment in our Common Shares could suffer a decline in value.***

Broad market and industry factors may adversely affect the price of our Common Shares, regardless of our actual performance. Factors that could cause fluctuation in the price of our Common Shares may include, among other things:

● changes in financial estimates by us or by any securities analysts who might cover our stock market performance;

● stock market price and volume fluctuations of other publicly traded companies and, in particular, those that are in the mining industry;

● speculation about our business in the press or the investment community;

● conditions or trends in our industry or the economy generally;

● decreases in the prices of gold;

● announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures;

● inability to find a development partner, investor or lender on acceptable terms for the development of Mt Todd;

● additions or departures of key personnel;

● loss of Common Share listing on the Toronto Stock Exchange (the "TSX") or the NYSE American due to noncompliance with exchange listing standards;

● issuance of Common Shares by the Company; and

● sales of our Common Shares , including sales by our directors, officers, or significant stockholders.

In the past, securities class action litigation has often been instituted against companies following periods of volatility in their stock price. This type of litigation or other securities claims could result in substantial costs to us and divert our management's attention and resources.

[**Table of Contents**](#Toc)

***Potential share dilution.***

Our constating documents allow us to issue an unlimited number of Common Shares for such consideration and on such terms and conditions as shall be established by the Board of Directors, in many cases without the approval of shareholders. We may issue Common Shares in offerings from treasury (including through the sale of securities convertible into or exchangeable for Common Shares) and on the exercise of stock options or other securities exercisable for Common Shares. We cannot predict the size of future issuances of Common Shares or the effect that future issuances and sales of Common Shares will have on the market price of the Common Shares. Issuances of a substantial number of additional Common Shares, or the perception that such issuances could occur, may adversely affect prevailing market prices for the Common Shares. With any additional issuance of Common Shares, investors will suffer dilution to their shareholder interest and voting power.

***Holders of our Common Shares may not receive dividends.***

We have not historically declared cash dividends on our Common Shares. Holders of our Common Shares are entitled to receive only such dividends as our Board of Directors may declare out of funds legally available for such payments. Our ability to pay dividends will be subject to our future earnings, capital requirements and financial condition, as well as our compliance with covenants related to any future indebtedness and would only be declared in the discretion of our Board of Directors.

**General Risks**

***We may experience cybersecurity breaches which may result in information theft, data corruption, operational disruption, disclosure of confidential business information, misdirected wire transfers, reputational harm, or financial loss.***

Regular access to and security of information technology systems are critical to our operations. To our knowledge, the Company has not experienced any material losses relating to disruptions to its information technology systems. We have implemented policies, controls, and practices to manage and safeguard our Company and stakeholders from internal and external cybersecurity threats and to comply with changing legal requirements and industry practice. Cyber risks cannot be fully mitigated, and these threats are continuing to evolve. Therefore, we cannot assure that its information technology systems are fully protected from cybercrime or that the systems will not be inadvertently compromised, or without failures or defects. Potential disruptions to our information technology systems, including, without limitation, security breaches, power loss, theft, computer viruses, cyber-attacks, natural disasters, and noncompliance by third party service providers and inadequate levels of cybersecurity expertise and safeguards of third party information technology service providers, may adversely affect our operations as well as present significant costs and risks including, without limitation, loss or disclosure of confidential, proprietary, personal or sensitive information and third party data, material adverse effect on its financial performance, compliance with its contractual obligations, compliance with applicable laws, damaged reputation, remediation costs, potential litigation, regulatory enforcement proceedings and heightened regulatory scrutiny.

[**Table of Contents**](#Toc)

***We are subject to anti-bribery and anti-corruption laws.***

Our operations are governed by, and involve interactions with, many levels of government in several countries. We are required to comply with anti-corruption and anti-bribery laws in the countries in which we conduct our business. In recent years, there has been a general increase in both the frequency of enforcement and the severity of penalties under such laws, resulting in greater scrutiny and punishment of companies convicted of violating anti-corruption and anti-bribery laws. Furthermore, a company may be found liable for violations committed by not only its employees, but also by its contractors and third-party agents. Although we have adopted internal control policies to mitigate such risks, there can be no assurance that our internal control policies and procedures will always protect us from recklessness, fraudulent behavior, dishonesty or other inappropriate acts committed by our affiliates, employees or agents and such measures may not always be effective in ensuring that we, our employees, contractors or agents will comply strictly with such laws. If we find ourselves subject to an enforcement action or are found to be in violation of such laws, this could lead to civil and criminal fines and penalties, investigation and litigation, and loss of operating licenses or permits, resulting in a material adverse effect on our reputation and results of operations.

***Our business is subject to evolving corporate governance and public disclosure regulations that have increased both our compliance costs and the risk of noncompliance.***

We are subject to changing rules and regulations promulgated by numerous governmental and self-regulated organizations, including but not limited to the British Columbia Securities Commission, the SEC, the TSX, the NYSE American, and the Financial Accounting Standards Board. These rules and regulations continue to evolve in scope and complexity and many new requirements have been created in response to laws enacted by the United States Congress, making compliance increasingly more difficult and uncertain, which could have an adverse effect on our reputation and our stock price.

***We are or may become subject to data privacy laws, regulations, litigation and directives relating to our processing of personal information.***

The jurisdictions in which we operate (including the United States) have laws governing how we must respond to a cyber incident that results in the unauthorized access, disclosure, or loss of personal information. Additionally, new laws and regulations governing data privacy and unauthorized disclosure of personal information and imposing certain cybersecurity-related requirements may provide for a private right of action and imposition of significant fines, pose increasingly complex compliance challenges. Some or all of such legislation will elevate our compliance costs over time. Our business involves collection, use, and other processing of personal information and personally identifiable information of our employees, investors, contractors, suppliers, and customer contacts. As legislation continues to develop and cyber incidents continue to evolve, we will likely be required to expend significant resources to continue to modify or enhance our protective measures to comply with such legislation and to detect, investigate and remediate vulnerabilities to cyber incidents that relate to data privacy. Any failure by us, or a company we acquire, to comply with such laws and regulations could result in reputational harm, loss of goodwill, penalties, liabilities, remediation costs, or mandated changes in our business practices, each of which has the potential to materially impact our financial condition.

**ITEM 1B. UNRESOLVED STAFF COMMENTS.**

**ITEM 1C. CYBERSECURITY.**

***Description of Processes for Assessing, Identifying and Managing Cybersecurity Risks***

Vista's system of internal controls includes consideration of cybersecurity risks. The Company uses technology and control procedures designed to mitigate cybersecurity risks, with our management team working to monitor, identify, assess, and respond to potential cybersecurity incidents that may threaten the Company. The system of controls also focuses on security awareness and training for employees and contractors with access to Company facilities or systems. Company management periodically reviews system and organization control reports (SOC 1, Type 2) for key outsourced information

[**Table of Contents**](#Toc)

systems to ensure that third-party data processing is subject to appropriate controls and security measures. Cybersecurity risks for Vista include the potential for financial loss, loss of data, and business interruption. Vista maintains technology and non-technology-based system controls, a data backup program, and disaster recovery testing to mitigate these risks.

Our cybersecurity controls also follow defense in depth principles, which aim to implement various layered access control, detection, prevention, and response measures. We periodically engage with third parties to assess our vulnerabilities and help us mitigate cybersecurity-related risks.

***Management's Role in Assessing and Managing Cybersecurity Risks***

The Company's chief executive officer ("CEO") and chief financial officer ("CFO") have primary responsibility for cybersecurity risk management and the implementation of processes for identifying, assessing, and managing material risks from cybersecurity threats. Officers of the Company and its Australian subsidiary review, at least quarterly, developments relevant to the Company's cybersecurity control environment. This group of officers has experience managing public companies and overseeing internal controls associated with cybersecurity. Additional support for information technology ("IT") general controls and specific cybersecurity matters is provided to the Company through third-party IT specialists. In accordance with the Company's policies, including its Disclosure Policy and Code of Business Conduct and Ethics, cybersecurity incidents are to be immediately reported to the Vista management team for resolution. Information technology general controls, including controls to mitigate cybersecurity risks, are considered by management during their assessment of the Company's design and effectiveness of internal controls over financial reporting. Findings from these control procedures are considered by management and, as deemed appropriate to reduce cybersecurity risks to an appropriately low level, are implemented. This may include modification of internal control procedures, adoption of technology solutions, and testing of specific elements of the system of controls.

***Board of Directors' Oversight of Risks from Cybersecurity***

Management, under supervision of the CEO and CFO, has developed a system of internal controls that identifies risks to the Company, designed controls intended to reduce risks to an appropriately low level, implemented control procedures, and subsequently tested such control procedures. Management presents an enterprise risk management assessment to the Audit Committee on a quarterly basis and provides the Audit Committee with frequent updates of specific financial statement risks. Risks associated with cybersecurity are included in these risk assessments, subjected to testing of key controls, and reflected in management's reports to the Audit Committee. The Board of Directors receives periodic briefings on selected risk matters, and is invited to participate in each Audit Committee meeting and, as such, is provided with the same information presented to the Audit Committee.

***No Previous Material Cybersecurity Threats***

We are not aware of any previous cybersecurity threats that have materially affected or are reasonably likely to materially affect the Company. Despite the security and risk management measures that we have implemented and any additional measures we may implement or adopt in the future, our facilities and systems, and those of our third-party service providers, have been and are vulnerable to security breaches, computer viruses, lost or misplaced data, programming errors, scams, burglary, human errors, acts of vandalism, misdirected wire transfers, or other malicious or criminal activities. A successful attack on our information or operational technology systems could have material consequences to the Company. While we devote resources to our security measures to protect our systems and information, these measures cannot provide absolute security. See "Item 1A. Risk Factors" for additional information about the risks to our business associated with a breach or compromise to our IT systems.

Certain capitalized terms in this section not otherwise defined herein have the meanings ascribed to them in the Mt Todd FS.

***Project Location, Access, Ownership and Climate***

Mt Todd is located 56 kilometers ("km") by road northwest of Katherine, NT, Australia, and approximately 290 km by road southeast of Darwin, NT. Access to the property is via high quality, two lane paved roads from the Stuart Highway, the main arterial within the territory.

The following figure illustrates the location of Mt Todd:

![Graphic](vgz-20251231x10k002.jpg)

The Project area has a sub-tropical climate with a distinct wet season and dry season. The area receives most of its rainfall between the months of December and March. Temperatures are moderate, allowing for year-round mining operations. The topography is relatively flat. The tenements encompass a variety of habitats forming part of the northern Savannah woodland region, which is characterized by eucalypt woodland with tropical grass understories. Surface elevations are approximately 130-160 meters above sea level in the area of the previous and planned site and waste rock dumps.

***Project Stage***

The Project is a development stage property with proven and probable Mineral Reserves.

***Feasibility Study Results***

The Mt Todd FS evaluates a 15 ktpd project that optimizes payable gold, capital efficiency, operating costs, and net present value ("NPV") at this scale.

The Mt Todd FS highlights include:

[**Table of Contents**](#Toc)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Estimated Proven and Probable Mineral Reserves of 5.2 million ounces of gold (172 million tonnes at 0.94 g Au/t) using a gold price of $1,800 per ounce for the Mineral Reserves estimate and a cut-off grade of 0.50 g Au/t <sup>(1)(2)</sup> ;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Initial capital of $425 million, a 59% reduction from the Company's feasibility study issued in 2024 for a 50 ktpd case;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Capital Efficiency of $93 per ounce (initial capital : total ounces of gold produced) <sup>(3)</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Benefit to Cost Ratio of 2.5 (NPV <sub>5%</sub> : initial capital) <sup>(3)</sup> ;

In November 2020, we modified our agreement with the Jawoyn Association Aboriginal Corporation ("Jawoyn Association"). The modified agreement provides the Jawoyn Association with a gross proceeds royalty ("GPR") ranging between 0.125% and 2.0%, depending on prevailing gold prices and foreign exchange rates, instead of its previous right to become a 10% participating joint venture partner in Mt Todd. The modified agreement did not affect the previously agreed 1.0% GPR. The combined royalty ("Jawoyn Royalty") ranges from 1.125% to 3.0%. Based on a gold price of $2,500/oz and the AUD/USD foreign exchange rates used in for the Mt Todd FS economic analysis, the Jawoyn Royalty was assumed to be 3.0%.

In December 2023, Vista entered into a royalty agreement with Wheaton Precious Metals (Cayman) Co., an affiliate of Wheaton Precious Metals Corp., in relation to Mt Todd (the "Royalty Agreement"). Pursuant to the terms of the Royalty Agreement, Vista granted Wheaton a royalty in the amount of 1% of gross revenue from the sale or disposition of minerals from the Project, subject to adjustments in certain circumstances (the "Wheaton Royalty"). Based on the timing to achieve

the Royalty Agreement's defined completion test, the Wheaton Royalty was assumed to be 1.13% for purposes of the Mt Todd FS economic analysis.

The production schedule contemplates 158.6 million tonnes of ore from the Batman deposit containing an estimated 4.96 million ounces of gold at an average grade of 0.97 g Au/t to be processed over a 30-year life of mine. As part of the closure plan, 13.4 million tonnes of heap leach pad material from previous operations containing an estimated 0.23 million ounces of gold will be reprocessed and then placed in Tailings Storage Facility ("TSF") 2. Cashflow from this closure activity provides a form of self-funding reclamation. Total gold to be produced is expected to be 4.55 million ounces. Average annual gold production over the life of mine is expected to be 146,000 ounces, which includes an average of 153,000 ounces per year during the first 15 years.

The following table summarizes the production schedule for the 30-year life of mine and the subsequent reprocessing of gold Mineral Reserves from the heap leach pad.

***Property Holdings***

In 2006, through an agreement with Pegasus Gold Australia Pty. Ltd. ("Pegasus"), the NT Government, and the Jawoyn Association, we acquired the concession rights and access to Mt Todd. Also in 2006, through an agreement with the NT Government, we established the rights and obligations of Vista and the NT Government with respect to Mt Todd site care and maintenance and potential future development. The latter agreement was extended in 2017 through the end of 2023 and further extended in 2023 through December 31, 2029, with the option for an additional three-year extension.

The surface land of the contiguous MLs and ELs is freehold land owned by the Jawoyn Association. Because the Jawoyn Association has title to the land, such land is not part of the lands classified by the government as Indigenous lands, and as a result such lands are not subject to an Indigenous land use agreement. Vista has a private agreement with the Jawoyn Association for access to the land.

Annually, we are required to submit an MMP (now called a Deemed Environmental (Mining) License) ("DEML") for care and maintenance that details work to be done on the property. We received our operational MMP (also now a DEML) in June 2021 based on the parameters of the 50 ktpd 2020 Mt Todd prefeasibility study. This authorization is the operating permit that sets out how the mine operating strategy will be implemented throughout the mine life in compliance with the associated approved EIS and Environmental Protection and Biodiversity Conservation Act 1999 ("EPBC") requirements. Modifications to align existing approvals with the plans and designs in the Mt Todd FS have been initiated.

***Infrastructure***

Because Mt Todd was an operating mine, certain existing infrastructure was contemplated for future use in preparing the Mt Todd FS and resulted in reduced initial capital expenditures in developing the economic analysis.

Existing infrastructure includes:

● TSF 1, with expansion capacity for approximately 90 million tonnes of additional material;

[**Table of Contents**](#Toc)

● a heap leach pad with approximately 13.4 million tonnes of Mineral Reserves to be reprocessed at the end of the mine life as a form of self-funding reclamation;

● initial stage of a waste rock dump;

● a freshwater reservoir with sufficient storage capacity to meet the Mt Todd FS raw water requirements;

● a natural gas pipeline spur to site that can supply sufficient natural gas to meet the Project's primary energy requirements;

● a paved road to site;

● current electrical connection to the NT electric grid; and

● miscellaneous other buildings and equipment that may be re-purposed.

In addition, we expect reduced earthworks costs due to the new process plant location being in the same general area as the previous process plant, which was cleared and graded at the time of original construction.

Other non-owned regional infrastructure that Vista expects to benefit Mt Todd include:

● the Stuart Highway, the main north/south highway in the NT, is less than 10 km from the Project;

● a rail line parallel to the Stuart Highway;

● a natural gas transmission pipeline also parallel to the Stuart Highway;

● the regional center of Katherine, with a population of approximately 14,000, is located 56 km from the Project site and provides access to various local commercial resources, short-term accommodations, schools and a satellite university, and the Katherine Tindal Civilian Airport; and

● the NT capital of Darwin is located approximately 290 km by road from the Project and provides access to a broad range of commercial resources, the deepwater Port of Darwin, the Darwin International Airport, and other resources common to a small-medium urban center.

Planned infrastructure for the site includes the following:

● mine infrastructure will be supplied and installed by a mining contractor and includes – workshop and warehouse, maintenance support facilities, contractor laydown and storage yards, fuel and lubricant farm, explosives storage and facilities, water cart filling point, mine administration and personnel facilities, information and communication systems;

● expansion of the existing waste rock dump;

● upgraded water retention pond dam below the waste rock dump;

● 250-person accommodation camp with all facilities;

● a water treatment plant;

● pit dewatering system;

● communications system;

● gatehouse;

● emergency services building;

● process plant and administration building;

● process plant workshop and stores building with offices;

● reagents storage facility;

● process plant control rooms;

● sample preparation and laboratory;

● solid and liquid waste disposal facilities; and

● expansion of TSF 1 and additional of a second tailings storage facility.

***Geological Setting, Mineralization, and Deposit Type***

The Project is situated within the southeastern portion of the Early Proterozoic Pine Creek Geosyncline. Meta-sediments, granitoids, basic intrusives, acidic and intermediate volcanic rocks occur within this geological province.

Within the Mt Todd region, the oldest outcropping rocks are assigned to the Burrell Creek Formation. These rocks consist primarily of interbedded greywackes, siltstones, and shales of turbidite affinity, which are interspersed with minor volcanics. The sedimentary sequence incorporates slump structures, flute casts and graded beds, as well as occasional

[**Table of Contents**](#Toc)

crossbedding. The Burrell Creek Formation is overlain by interbedded greywackes, mudstones, tuffs, minor conglomerates, mafic to intermediate volcanics and banded ironstone of the Tollis Formation. The Burrell Creek Formation and Tollis Formation comprise the Finniss River Group. The Finniss River Group strata have been folded about northerly trending F1 fold axes, which are folds in bedding. The folds are closed to open style and have moderately westerly dipping axial planes with some sections being overturned. A later north-south compression event resulted in east-west trending open style upright D2 folds, which is associated with the second deformation event in the area. The Finniss River Group has been regionally metamorphosed to lower green schist facies.

Late and Post Orogenic granitoid intrusion of the Cullen Batholith occurred from 1,789 Ma to 1,730 Ma and brought about local contact metamorphism to hornblende hornfels facies. Unconformably overlying the Burrell Creek Formation are sandstones, shales and tuffaceous sediments of the Phillips Creek sandstone, with acidic and minor basic volcanics of the Plum Tree Creek Volcanics. Both of these units form part of the Edith River Group and occur to the south of the Project area.

The geology of the Batman deposit consists of a sequence of hornfelsed interbedded greywackes, and shales with minor thin beds of felsic tuff. Bedding is striking consistently at 325°, dipping at 40° to 60° to the southwest. Minor lamprophyre dykes trending north-south pinch and swell, cross cutting the bedding.

Bedding parallel shears are present in some of the shale horizons. These bedding shears are identified by quartz/calcite sulfidic breccias. Pyrite, pyrrhotite, chalcopyrite, galena and sphalerite are the main primary sulfides associated with the bedding parallel shears.

East-west trending faults and joint sets crosscut bedding. Only minor movement has been observed on these faults. Calcite veining is sometimes associated with these faults. These structures appear to be post mineralization.

Northerly trending quartz sulfide veins and joints striking at 0° to 20°, dipping to the east at 60° are the major location for mineralization in the Batman deposit. The veins are 1 millimeter ("mm") to 100 mm in thickness, with an average thickness of around 8 mm to 10 mm. The veins consist of dominantly quartz with sulfides on the margins. The veining occurs in sheets with up to 20 veins per horizontal meter ("m"). These sheet veins are the main source of mineralization in the Batman deposit.

The Batman deposit extends approximately 2,400 m along strike, 600 m across dip and drill tested to a depth of 800 m. Drilling indicates the Batman mineralization to be open along-strike and down-dip.

The mineralization within the Batman deposit is directly related to the intensity of the north-south trending quartz sulfide veining. The lithological units impact on the orientation and intensity of mineralization. Sulfide minerals associated with the gold mineralization are pyrite, pyrrhotite and lesser amounts of chalcopyrite, bismuthinite and arsenopyrite. Galena and sphalerite are also present, but appear to be post-gold mineralization, and are related to calcite veining in the bedding plains and the east-west trending faults and joints. Two main styles of mineralization have been identified in the Batman deposit. These are the north-south trending vein mineralization and bedding parallel mineralization. 

The north-south trending mineralization in the Batman deposit occurs in all rock units and is most dominant in the shales and greywackes. The north-south trending mineralization can be divided into three major zones based on veining and jointing intensity. Mineralization in the core complex is consistent and most, to all, joints have been filled with quartz and sulfides. The core complex occurs in all rock types and vein frequency per meter is high. Mineralization in the hanging wall zone is patchier than in the core complex due to quartz veining not being as abundant as it is in the core complex. The lithology controls the amount of mineralization within the hanging wall zone, and a large quartz/pyrrhotite vein defines the boundary of the hanging wall zone and core complex in places. Like the hanging wall zone, the footwall zone mineralization is patchier than is found in the core complex and jointing is more prevalent than quartz veining. Footwall zone mineralization style is controlled by the lithology and occurs in all lithological units.

Additionally, bedding parallel mineralization occurs to the east of the Batman core complex. Veining is both bedding parallel and north south trending. The mineralization appears to have migrated from the south along narrow north-south trending zones and ballooned out parallel to bedding around the felsic tuffs.

***Historical Operations***

The Mt Todd area is part of a goldfield that was worked from early in the 20th century. Gold and tin were discovered in the Mt Todd area in 1889. Most deposits were worked during the period from 1902 to 1914. A total of 7.80 tonnes of tin concentrate was obtained from cassiterite-bearing quartz-kaolin lodes at the Morris and Shamrock mines. The Jones Brothers reef was the most extensively mined gold-bearing quartz vein, with a recorded gold production of 28.45 kilograms ("kg").

The Yinberrie Wolfram field, discovered in 1913, is located 5 km west of Mt Todd. Tungsten, molybdenum, and bismuth mineralization was discovered in greisenized aplite dykes and quartz veins in a small stock of the Cullen Batholith. Recorded production from numerous shallow shafts is 163 tonnes of tungsten, 130 kg of molybdenite and a small quantity of bismuth. Exploration for uranium began in the 1950s. Small uranium prospects were discovered in sheared or greisenized portions of the Cullen Batholith in the vicinity of the Edith River. The area was explored previously by Esso for uranium without any economic success.

Australian Ores and Minerals Limited ("AOM") in joint venture with Wandaroo Mining Corporation and Esso took out a number of mining leases in the Mt Todd area during 1975. The joint venture conducted reconnaissance work for a variety of commodities and drilled two diamond holes at Quigleys. Despite determining that the gold potential of the reefs in the area was promising, their work ceased around Mt Todd.

The Arafura Mining Corporation, CRA Exploration, and Marriaz Pty Ltd all explored the Mt Todd area at different times between 1975 and 1983. In late 1981, CRA Exploration's program included a 14-diamond drill hole program to test the gold content of Quigleys reef over a strike length of 800 m, with an aggregate meterage of 676.5 m. Following this program, CRA Exploration did not proceed with further exploration.

During late 1986, Pacific Gold Mines NL (Pacific Gold Mines) undertook exploration in the area which resulted in small-scale open cut mining on the Quigleys and Golf reefs, and limited test mining at the Alpha, Bravo, Charlie and Delta pits. Ore was carted to a carbon-in-pulp ("CIP") plant owned by Pacific Gold Mines at Moline. Pacific Gold Mines ceased operations in the area in February 1988 having produced approximately 86,000 tonnes grading 4 g Au/t. Subsequent negotiations between the Mt Todd Joint Venture partners (Billiton Australia Gold Pty. Ltd ("Billiton") and Zapopan) and Pacific Gold Mines resulted in the acquisition of this ground and incorporation into the joint venture.

Billiton, who was the managing partner in an exploration program in joint venture with Zapopan, discovered the Batman deposit in May 1988. Zapopan acquired Billiton's interest in 1992 by way of placement of shares to Pegasus. Pegasus progressively increased their shareholding until they acquired full ownership of Zapopan in July 1995. Feasibility studies (not NI 43-101 or S-K 1300 compliant) for Phase I, a heap leach operation which focused predominately on the oxide portion of the deposit, commenced during 1992. The Phase I project was predicated upon a 4 million tonne per annum ("Mtpa") heap leach pad, which came on stream in late 1993. The treatment rate was subsequently expanded to a rate of 6 Mtpa on an annualized basis in late 1994.

Historical heap leach production is shown in the following table:

Phase II involved expanding to 8 Mtpa and treatment through a flotation and CIL circuit. A feasibility study was conducted by a joint venture between Bateman Kinhill and Kilborne ("BKK") and was completed in June 1995. The Pegasus board approved the Phase II project on August 17, 1995, and awarded an EPCM contract to BKK in October 1995. Commissioning commenced in November 1996. The reported final capital cost to complete the project was A$232 million.

Design capacity was never achieved due to inadequacies in the crushing circuit. A throughput rate of just under 7 Mtpa was achieved by mid-1997; however, problems with the flotation circuit, which resulted in reduced recoveries, necessitated closure of this circuit. Subsequently, high reagent consumption because of cyanide soluble copper minerals further hindered efforts to reach design production. Operating costs were above those predicted in the feasibility study. The spot price of gold deteriorated from above $400 per ounce in early 1996 to below $300 per ounce during 1997. According to the 1997 Pegasus Annual Report, the economics of the project were seriously affected by the slump. Underperformance of the project and higher operating costs led to the mine being closed and placed on care and maintenance on November 14, 1997.

In February 1999, General Gold Resources Pty. Ltd. ("General Gold") agreed to form a joint venture with Multiplex Resources Pty Ltd ("Multiplex Resources") and Pegasus to own, operate, and explore the mine. Initial equity participation in the joint venture was General Gold 2%, Multiplex Resources 93%, and Pegasus 5%. The joint venture appointed General Gold as mine operator, which contributed the operating plan in exchange for a 50% share of the net cash flow generated by the project, after allowing for acquisition costs and environmental sinking fund contributions. General Gold operated the mine from March 1999 to July 2000. Pegasus, through the Deed Administrators, regained possession of various parts of the mine assets to recoup the balance of purchase price owed to it. Most of the equipment was sold in June 2001 and removed from the mine.

In March 2006, Vista acquired the MLs from the Deed Administrators and surface access rights from the Jawoyn Association and entered into a contract with the NT Government.

***Exploration Licenses***

Since acquiring the Mt Todd ELs, Vista has conducted exploration programs that included prospecting, geologic mapping, rock and soil sampling, geophysical surveys and exploration drilling.

The exploration effort initially focused on follow up work on targets developed by Pegasus during their tenure on the property. These included the RKD target, Golden Eye, and Silver Spray, among others. During a review of Pegasus' airborne geophysical survey data, five distinct magnetic highs were observed located within sedimentary rocks that should have a low magnetic signature. These features are remarkably similar to those at the Batman deposit, which, as a result of the included pyrrhotite, exhibits a strong magnetic high. The geophysical targets were prioritized following review of historical work in the area and site visits. To date, two of the geophysical targets (Golden Eye and Snowdrop) have had some drilling and a third has been covered by soil sampling (Black Hill). The Wandie target has a different

[**Table of Contents**](#Toc)

magnetic signature, where field examination identified small-scale pits on an iron-rich outcropping. There are no reportable Mineral Resources or Mineral Reserves on the ELs, and no data from the ELs were used in the development of the Mt Todd FS results.

The quantity and type of exploration samples collected on the ELs is summarized in the following table.

A large percentage of the historical drilling was by reverse circulation drilling of less than 100 m in depth. Vista's drilling discovered a larger Batman Mineral Resource by probing deeper with diamond drilling averaging 550 m in depth. Most of the diamond drilling was angled to be approximately perpendicular to the mineralization. This orientation more accurately transects the true thickness of the mineralization.

Eight drill holes were completed for metallurgical testing in 2017-2018. These holes were not included in the Mineral Resource estimation due to a difference in the data collection and type. The data from the metallurgical drilling was used as a verification check of the Mineral Resource model estimation in section view.

Vista drilled additional holes during 2020-2022 and 2024. The 2024 drilling program consisted of infill drilling at the Batman deposit, as well as step out drilling to define the mineralization in the area to the north and northeast of the Batman deposit, towards the historical Golf-Tollis pits. This area has been named the South Cross Lode zone ("SXL"). The 2020-2022 and 2024 holes were included in the Mt Todd FS.

Four drill holes were completed for metallurgical testing in late 2025 and early 2026. The mineralized intervals were assayed to assist in the selection of sample composites for the testing program.

*Quigleys Deposit*

The table below shows the Quigleys deposit drilling history. The Quigleys deposit was mined from 1982 to 1987 during which time the largest amount of drilling was percussion type used for ore grade control.

Relevant intervals of mineralization are contained within blanket-like zones which are modelled with 3-D wireframes for Mineral Resource estimation. Most of the drilling has been angled to be approximately perpendicular to the mineralized core zone. This orientation more accurately transects the true thickness of the mineralization. While there are random high-grade intercepts outside of the core zone, most higher-grade mineralization resides within the defined zones. In 2011, Vista explored the potential for a deeper deposit with three diamond drill holes, each over 350 m in depth.

*Drilling Results*

The results of drilling at the Batman deposit and Quigleys deposit were used to estimate gold Mineral Resources and Mineral Reserves. Vista's drilling discovered a larger Batman Mineral Resource by probing deeper with diamond drilling, which averaged approximately 550 m in depth. While there are random high-grade intercepts outside of the Batman core zone, most higher-grade mineralization at Batman resides within the core zone of the deposit. Relevant intervals of mineralization at the Quigleys deposit are contained within blanket-like zones which are modeled with 3-D wireframes for Mineral Resource estimation. While there are random high-grade intercepts outside of the Quigleys core zone, most higher-grade mineralization resides within the defined zones.

*2020-2022 Drilling Program Results and Exploration Targets* 

Between late 2020 and early 2022, we completed an exploration drilling program designed to demonstrate that the Batman, Golf Tollis, and Quigleys deposits are not independent of each other but connected by structure and mineralization. This program consisted of 26 drill holes totaling 8,887 m of HQ diamond core. The program consistently intersected mineralization predicted by our geologic model and demonstrated both horizontal and vertical continuity of the targeted structures. Additionally, the program identified four quality exploration targets as well as other potential structures along a 5.4 Km portion of the 24 Km Batman-Driffield Trend that contains the Batman, Golf Tollis, and Quigleys deposits.

*2024 Drilling Program Results and Exploration Targets*

During 2024, we completed a drilling program designed to upgrade the Mineral Resources, validate mineralization extension at the north portion of the Batman deposit and add gold ounces within the existing Batman resource shell, as well as define the boundaries of the SXL. This program consisted of 34 drill holes totaling 6,776 m of HQ diamond core. The program consistently intersected mineralization within the Batman deposit resource shell and along strike of the SXL. Results to date support the thesis that the structure remains open at depth and along the strike to the northeast of the concession.

***Sampling, Analysis and Data Verification***

The following section describes the sample preparation, analyses and security undertaken by Vista through the Mt Todd FS Mineral Resource update.

The diamond drilling program was conducted under the supervision of Vista's geology staff composed of a chief geologist, several experienced geologists, and a core handling/cutting crew.

Facilities for the core processing included an enclosed logging shed and a covered cutting and storage area that is fenced in. Both of these facilities are considered to be limited access areas and kept secured when work is not in progress.

The diamond drill core was boxed and stacked at the rig by the drill crews. Core was transported directly into the logging shed by Vista staff.

Processing of the core included photographing, geotechnical and geologic logging, and marking the core for sampling. The nominal sample intervals were one meter. When this process was complete, the core was moved into the core cutting/storage area where it was laid out for sampling. The core was laid out using the following procedures:

● One meter depth intervals were marked out on the core by a member of the geology staff.

● Core orientation (bottom of core) was marked with a solid line when at least three orientation marks aligned and used for structural measurements. When orientation marks were insufficient, an estimation orientation was indicated by a dashed line.

● Lithology, mineralogy, alteration, and geotechnical logging was then done by a member of the Vista geology staff in the core logging facility. Assay intervals were selected at that time and a cut line was marked on the core. The standard sample interval was one meter, with a minimum of 0.2 m and a maximum of 1.2 m. The sample interval was selected to have the identified vein in the middle of the sample, when possible.

● Blind sample numbers were then assigned based on pre-labeled sample bags. Sample intervals were then indicated in the core tray at the appropriate locations.

● Each core tray was photographed at a photography station, with a mounted camera, light and water sprayer, and then transported to the cutting area via a roller conveyor.

● The core was then cut in half using diamond saws, with each interval half-core placed in sample bags with a sample tag.

● The standards and blanks were also placed in the plastic bags for inclusion in the shipment to the laboratory, with a reference standard or a blank inserted at a minimum ratio of 1 in 10 and at suspected high grade intervals additional blanks sample were added.

[**Table of Contents**](#Toc)

● Standard reference material was sourced from Ore Research & Exploration Pty Ltd and provided in 60 g sealed packets. The standards were selected from the six commercially purchased standards at site, which are stored under refrigeration.

● When a sequence of five samples was completed, they were placed in a shipping bag and closed with a zip tie. All samples were kept in the secure area until crated for shipping.

● Samples were placed in crates for shipping with 100 samples per crate (20 shipping bags). The crates were stacked outside the core shed until transport.

● Samples were delivered to the laboratory by Vista staff.

The following laboratories have been used for sample preparation, analyses, and check assays:

Vista is independent of each of the above listed analytical testing entities, other than the engagement of said entities as a service provider.

Prior to the 2011 drilling campaign, the majority of samples were transported first to ALS in Alice Springs, NT for sample preparation. After preparation, samples were then forwarded on to ALS in Malaga, Western Australia for assay analyses. One in every 20 pulps or rejects was sent from ALS in Alice Springs to NAL, and Vista was notified by email which samples were sent.

For the 2011-2025 drilling campaign, samples for assay were sent to NAL in Pine Creek, NT. At the end of each drilling campaign, Vista also submitted samples to Intertek in Darwin and Perth for confirmation of the NAL values. This umpire sampling is standard practice and meets the requirements for QA/QC on a project at this level.

The crushing equipment is cleaned between samples, and the laboratory processes one job at a time, to ensure that there is no cross contamination. LIMS software is used to track the samples and the results, as well as tracking the QA/QC standards for the facility. Certified standard material from Ore Research & Exploration Pty Ltd is utilized for QA/QC purposes for the laboratory.

The procedure defined by the Vista geology staff was to duplicate the fire assay of any sample that has an assay value greater than 10 ppm. Any discrepancies in the testing initiated a re-assay of the samples, before reporting data to Vista. Results were transmitted to the Vista geologist by email, including an un-editable PDF file, and an Excel file. Overall, the laboratory met the requirements for testing and was appropriate for samples of this type. Vista is completely independent of any analytical testing entity presented herein.

Each of the laboratories listed follow their own quality controls based on international standards and accredited methods specified by ISO/IEC 17025 in North America and Australia. The standards specify sample preparation procedures, analytical methods and set of quality control steps that the laboratory should follow, including:

● How the sample should be coded to obscure its relationship to the drilling geometry.

● How the received sample should be prepared.

● The analytical steps to be taken.

● Given the required detection level and material analyzed, what instruments should be employed.

● Internal quality controls should be done such as: periodic assaying of duplicate samples, the insertion of certified calibration samples; utilizing blanks; and including a required number of randomized samples.

Regarding data verification, this section summarizes the extensive verification efforts undertaken from 2007 to 2024, highlighting the methodologies employed to validate both historical and recent assay results. Through systematic audits, inter-laboratory comparisons, and quality control measures, these verification activities ensure that the assay data used for Mineral Resource modeling meets the various requirements for gold projects.

In 2007, a verification exercise was conducted as part of the exploration program to validate historical assay results and ensure compliance with reporting standards for Mineral Resources. This program included re-assaying a portion of historical drill holes and analyzing new core drill holes. A multi-phase approach was implemented to assess the accuracy of gold assays generated by NAL on Mt Todd core samples. The phases included cross-checking assay standards between NAL and ALS, preparing and assaying intervals of remaining half-core, and conducting screen sieve assay analysis of coarse reject samples. The findings indicated that finer material tended to yield higher grades, which were lost during handling. Consequently, Vista adopted commercial polyester sample bags to mitigate this issue. The inter-laboratory analyses demonstrated strong reproducibility across all tests, particularly at grade ranges typical of the deposit.

In 2011, an external audit by Mine Development Associates reviewed the quality of 12,365 assays in the database, focusing on records related to in situ mineralization. The review revealed that 95% of these records had corresponding gold values in source documents. Among the historical assays, eight significant outliers were identified, confirming discrepancies between the database and source documents. The audit concluded that the historical and Vista assays in the Mt Todd database are reliable for Mineral Resource modeling.

For the March 2018 Mineral Resources estimates, Tetra Tech conducted a detailed verification of the assay database, which included results from the 2012-2017 exploration programs. This involved comparing assay results with laboratory certificates and reviewing field QA/QC samples. The analysis of 13 drill holes from the 2012 program and nine from the 2015-2017 programs showed no significant errors, although one drill hole had erroneous selenium results, which were corrected. A spot-check of approximately 14% of the database against laboratory certificates confirmed a 100% correlation of reported values. Field QA/QC samples were also analyzed, revealing that the majority fell within acceptable limits, with only a few exceptions.

The verification process continued through the 2020 to 2022 program, where each sample interval was assayed at NAL. Assays for gold were conducted using fire assay methods, with additional multi-element analyses performed. Independent laboratory checks by Intertek Genalysis Perth (INT) were also carried out to further validate the results.

In 2024, Tetra Tech professionals visited the NAL facility to observe the ongoing processing of samples from the Vista 2024 drill program. The verification procedures adhered to the standards outlined in S-K 1300. The assay results were meticulously entered into the database after thorough checks by Vista's senior geologist.

Quality control samples, including CRMs and blanks, were incorporated into the sampling sequence to monitor for contamination and ensure data integrity. The results from the independent laboratory checks indicated a strong correlation with NAL's assays, affirming the reliability of the data for the Mineral Resource estimation at Mt Todd.

*Sample Security*

NAL was the primary laboratory used for Vista's drilling programs. The NAL laboratory is located in the town of Pine Creek, approximately 65 km distant by road from Mt Todd site. A sample transmittal form was prepared and included with each shipment and a copy is filed in the geologist office on site.

When a shipment leaves the site, sample transmittals were prepared and e-mailed to NAL. When the shipment arrived at the preparation facility the samples were lined out and a confirmation of sample receipt was e-mailed back to Vista. Following completion of assay results, all pulps and reject material was shipped back to the Project site and stored.

Vista has completed more than 60,000 m of core drilling in the Batman deposit, to verify the approximately 98,000 m of historical drilling. Statistical analysis of the various drilling populations and QA/QC samples has not identified or highlighted any reasons to not accept the data as representative of the tenor and grade.

***Mining Operations***

The Mt Todd FS contemplates that the Batman deposit will be mined in eight stages using a conventional truck and excavator approach with all material requiring drilling and blasting for fragmentation prior to excavation. Mining operations will be undertaken via contract mining with the contractor utilizing 400 tonne class excavators and 190 tonne class rigid frame trucks.

Multiple stages will be developed at any one time to manage mill feed tonnage and grade requirements, waste movement and stockpile balances.

Ore material will be designated as high grade, medium grade, or low grade with approximately 15 ktpd being fed to the processing plant. High and medium grade material not fed directly to the processing plant will be stockpiled on a run of mine pad adjacent to the processing plant. Low grade material will be placed on a dedicated low-grade stockpile.

Based on its sulfur content, waste material will be classified as non-acid forming or potentially acid forming ("PAF") with management plans and dumping strategies in place to ensure containment of the PAF material on a single waste rock landform. Mined unclassified waste material with no sulfur assays will be deemed as low level PAF.

***Mineral Processing***

The Mt Todd processing facility has been designed to process 15 ktpd of hard ore from the Batman open pit, equating to an annualized throughput rate of 5.325 Mtpa.

The processing facility unit processes are based on well-proven technologies for gold recovery and treatment of hard ore, following a processing circuit consisting of:

● Primary crushing in open circuit using a gyratory crusher to produce a nominal product P <sub>80</sub> of 120 mm.

● Secondary crushing incorporating a cone crusher operating in closed circuit with a double deck vibrating screen to produce a nominal circuit product P <sub>80</sub> of 30 mm.

● Coarse ore stockpile (COS) with reclaim via apron feeders.

● Tertiary crushing circuit incorporating a HPGR in closed circuit with two double deck wet vibrating screens to produce a nominal circuit product P <sub>80</sub> of 3.25 mm.

● Sorting the HPGR product screen top deck oversize -29.5+16 mm fraction with a single stage of XRT ore sorters.

● Primary grinding in an overflow ball mill operating in closed circuit with hydro-cyclones to a produce P <sub>80</sub> of 250 µm.

● Secondary grinding utilizing four Vertimill mills operating in parallel to produce P <sub>80</sub> of 40 µm.

● Pre-leach thickening to produce an underflow of increased pulp density suitable for leaching.

● Conditioning/pre-oxidation of the leach feed slurry with lead nitrate and oxygen in two agitated pre-conditioning/oxidation tanks.

● Direct cyanide leaching and adsorption in a hybrid CIL circuit comprising two leach tanks followed by six adsorption tanks.

[**Table of Contents**](#Toc)

● Acid washing and elution of the loaded carbon in a split AARL elution circuit, and thermal regeneration of the barren carbon prior to its return to the CIL circuit.

● Smelting of cathode sludge from electrowinning to produce the final gold doré product.

● Detoxification of leach tailings via the Air/SO2 process.

● Transfer of the final tailings to the TSF for deposition with the supernatant water recovered from the surface of the TSF for re-use in the process plant.

An overall schematic flowsheet depicting the unit operations incorporated in the selected process flowsheet is presented below.

***Metallurgical Testing***

No new metallurgical test work has been completed since 2019. The Company is currently undertaking a metallurgical testing program to provide data for detailed engineering and design, with results expected mid-year 2026. Consideration of the results of our prior metallurgical testing resulted in the process flowsheet presented above. The only significant change to the process flowsheet between the 2024 FS and the Mt Todd FS was the exclusion of laser sorting.

Our metallurgical testing programs have confirmed: (1) ore hardness of the Batman deposit is consistent throughout the deposit; (2) the selection of HPGR crusher technology as part of the comminution circuit; (3) the selection of ore sorting (XRT) technology to eliminate waste material after crushing and prior to grinding; (4) estimated gold recovery rates based on optimized grind size and leach conditions; and (5) the processing of material from the historical heap leach pad at the end of the proposed life of mine.

[**Table of Contents**](#Toc)

The test work results collated from the 2011 and 2012 testing campaigns and additional metallurgical and process test work conducted in 2016, 2017, 2018, and 2019, together with the process design criteria, were used to develop the process flow sheet and mass balance.

*Ore Hardness*

Bond ball mill work indices ("BWi") were determined at a grind size of P<sub>80</sub> of 100 mesh for the various products, namely HPGR crusher, ore-sorting, composite samples and waste material.

The test results indicate the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● The BWi for the ore sorter feed (+5/8" screened HPGR crusher product) was higher than the composite samples prepared from the -5/8" screened HPGR crusher product. Hence, it is reasonable to conclude that the uncrushed material from the HPGR is harder than the crushed product.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● The rejected waste material had a BWi higher than both the composite sample prepared from the -5/8" HPGR crusher product and the XRT ore sorting product that is returned to the HPGR crushers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● The BWi for the final HPGR product ranged from 23.10 to 26.63. A BWi of 24.50 was selected for the design of the primary ball mill circuit.

*HPGR Crusher Selection*

The proposed 15 ktpd project comminution circuit incorporates the use of a gyratory crusher followed by secondary cone crushing. Secondary crushed ore will be further crushed by a tertiary stage HPGR to produce a ball mill feed. XRT ore sorting has been included on the HPGR circuit.

HPGR testing was conducted in 2018, the drill core was HPGR crushed and screened at 16 mm (5/8") at the facilities of Thyssen Krupp Industries near Dusseldorf, Germany. HPGR testing was also conducted at Weir Metals. The screened +16mm material was sent to the test facility of Tomra Sorting Solutions near Hamburg, Germany.

The test work confirmed prior test work and supports the comminution circuit design. The use of HPGR crushers is anticipated to (a) produce a product that can be ground more efficiently (lower BWi); and (b) reduce energy requirements when compared to a SAG Mill design.

The crushing circuit design utilizing a primary gyratory crusher, secondary cone crusher and HPGR tertiary crushing is robust, proven technology to generate a grinding circuit feed F80 size of 3.25 mm.

*Ore Sorting*

The +16 mm composite fractions were sent to the Tomra-Outotec for ore sorting assessment. The fractions were weighed on arrival and washed to remove fines which were accounted for within the mass balance. The composites were split into equal fractions with each fraction subjected to two-step sorting design to separate gold bearing sulfide mineralization and quartz from non-fold bearing waste material. The first step used XRT to separate material based on density to target the gold bearing sulfide material with a higher specific gravity. Two different sensitivities were tested (2% and 5%). The second stage used laser to separate out the quartz (gold bearing) mineralization from the gangue non-gold bearing waste.

On a material mass basis, sorting tests confirmed that a single-stage XRT sorting circuit is expected to:

● reject approximately 8% of the run-of-mine feed as waste; and

● produce a gold loss from the rejected waste of approximately 1.7%.

*Gold Recoveries*

A series of batch leach tests were performed on six composites to evaluate the effect of feed grade against gold extraction at various grind sizes at the ALS Metallurgy Laboratory in Australia. A total of 123 tests were conducted including duplicate tests. Alternative milling types were also applied to the test procedure, utilizing an FLS VXP mill, IsaMill and a

[**Table of Contents**](#Toc)

Lab steel ball mill.

The tests demonstrated that gold extraction is size dependent, increased gold extraction was recorded with finer grind size. In the same manner, a correlation that relates mill feed gold grade to gold extraction was derived from the historical leach test work for predicting gold recoveries in the plant according to the production schedule. The test results from both the 2018 and 2019 leach tests were used to derive the gold recovery model, based on mill feed gold grade. The samples selected for gold head grade analysis ranged from 0.6 g/t to 2.1 g/t Au. Tests done on samples reported grind sizes well below the design P<sub>80</sub> size of 40 µm were excluded from the assessment.

A carbon adsorption efficiency of 99.1% for gold has been factored for an average gold recovery of 89.9% (net of solution loss) based on mill feed from the life of mine average gold head grade of 0.97 g Au/t. This equates to 88.5% based on the processing plant feed.

*Existing Heap Leach Pad*

A historical heap leach pad adjacent to the current Mt Todd pit was analyzed for gold. The heap leach pad is a remnant of the Pegasus operation, pre-2006. The heap leach pad's geometry was analyzed using historical maps to determine the pile bottom and current surveys of the present-day surface. This work produced two surfaces which were used to calculate the volume of the pile. The concentration of gold was analyzed with 24 vertical drillholes separated by approximately 100 m. Density was measured using a dual density sidewall gamma probe. A total of 1,162 samples were collected from 11 drill holes, and the density was estimated to be 2.01 for the heap leach pad material.

A nearest neighbor method was employed to estimate grades within the heap leach pad since there is no apparent spatial correlation between samples. The existing heap leach pad is estimated to contain 232,000 ounces of gold within 13.4 million tonnes at an average grade of 0.54 g Au/t.

Bottle roll and column leach test work undertaken at the ALS Metallurgy Laboratory in Australia indicated:

● Cyanidation leach tests on "as is" material on the heap will extract ± 30% of the gold; and

● CIP cyanidation tests at a grind size of P <sub>80</sub> of 90 μm will extract on average 72% of gold (range: 64.14% to 80.37%) in 24 hours of leach time. The average lime and cyanide consumptions were 1.75 kg/t and 0.78 kg/t, respectively.

The heap leach pad ore material will be reprocessed following processing of ore from the Batman deposit. Reprocessing of this material, with gold recovery estimated at 72%, will be completed as part of self-funded reclamation and closure activities. Following reprocessing of this material, the leap leach pad footprint will be reclaimed by cutting and removing the liner for consolidation in TSF 2.

***Permitting***

Vista has initiated activities to modify its existing authorizations to align with the designs and operating plans as set out in the Mt Todd FS and to obtain an additional AAPA Authority Certificate to cover additional project activity areas. The history of existing authorizations that Vista is presently seeking to modify includes:

In September 2014, the EIS was approved. In its Assessment Report, the NT EPA advised that it had assessed the environmental impacts of Vista's development plans for Mt Todd and concluded that it can proceed, subject to a number of recommendations as outlined in the Assessment Report. The NT EPA Assessment Report includes 28 recommendations which were addressed as part of the subsequently approved MMP.

The approval of the EIS resulted in a requirement to obtain an authorization of a controlled activity as required under the EPBC as it relates to the Gouldian Finch. The EPBC authorization of a controlled activity was granted by the Australian Commonwealth Department of Environment and Energy in January 2018.

[**Table of Contents**](#Toc)

In November 2018, we applied for an MMP approval, which is the operating permit that sets out how the mine operating strategy will be implemented throughout the life of mine in compliance with the EIS and EPBC requirements. The MMP was approved in June 2021. As a result of changes in legislation by the NT Government, in July 2024 all MMPs were converted to DEMLs with the same rights and obligations in regard to the operating plans for Mt Todd previously conferred by the MMP. All companies have four years from July 2024 to convert a DEML to an EML. In most cases, existing designs and management plans will be submitted for review and are expected to receive subsequent approval as an EML.

In 2012 and 2021, authority certificates were issued to Vista under the NT Aboriginal Areas Protection Act ("AAPA Authority Certificate") that indicate the nature of, and areas where, project activities can proceed without risk of damage or interference with Aboriginal sacred sites. We also hold permits to interfere with a waterway and a water extraction license.

***Environmental, Social and Community Factors***

A number of environmental studies have been conducted at Mt Todd in support of the EIS and as required for environmental and operational permits. Studies conducted have investigated soils, climate and meteorology, geology, geochemistry, biological resources, cultural and anthropological sites, socio-economics, hydrogeology, and water quality.

The EIS for the Project was submitted in June 2013. The document was prepared by independent consultants, GHD Pty Ltd., to identify potential environmental, social, transport, cultural and economic impacts associated with reopening and operating the mine. NT EPA provided its final assessment of the Project in June 2014. Final approval was given in September 2014. The EIS is among the authorizations that Vista is seeking to modify to align with the designs and plans in the Mt Todd FS.

The Jawoyn Association has been consulted as part of the planning process for the future of the Project. Areas of Aboriginal significance have been designated, and the mine plan has avoided development in these areas. Consultation with the Jawoyn Association is ongoing, including in regard to Vista's plans to obtain an additional AAPA Authority Certificate.

***Water Treatment***

The existing Batman pit has the capacity to contain approximately 11.5 gigaliters ("GL") of water. Historically, we have treated and discharged approximately 10.5 GL of treated water from the site in compliance with a waste discharge license issued by the NT Government. The Batman pit is used for ongoing water management to store excess water from other site locations. As of December 31, 2025, the volume of water in the pit was approximately 4.1 GL; however, this volume has increased to approximately 5.3 GL as a result of abnormally heavy seasonal precipitation. Beginning in 2025, the Company implemented an enhanced evaporation program to stabilize and begin reducing the overall volume of water on site. The Company is also in the planning stages for a program to begin treating and discharging the accumulated water in preparation for the resumption of operations.

Water treatment of acid rock drainage and metal laden water will occur once Project development begins. A water treatment plant will be installed for active water treatment prior to operations, during mining operations, and for a period following cessation of operations. Passive water treatment will be conducted at the site following closure in addition to use of the active water treatment plant, as required.

***Project Development Plans***

With completion of the Mt Todd FS, the Company has started activities expected to lead to the transition of Mt Todd to a producing operation. The Company has filed modifications and is preparing additional filings to align its existing major permits and approvals with the current Mt Todd FS parameters. The Company is undertaking studies that address recommendations in the Mt Todd FS to optimize the development plan and provide data for detailed engineering. To achieve its objectives, Vista will also advance plans to build the internal organizational capabilities and obtain the financing needed to make the transition of Mt Todd to a producing operation.

[**Table of Contents**](#Toc)

The Company estimates recurring expenditures for the ensuing twelve months following December 31, 2025, will total approximately $9,100, including $4,600 for its Mt Todd site management, environmental stewardship activities, and expanding its corporate capability by building an Australia-based team. Additionally, expenditures of approximately $10,200 in non-recurring project program costs are estimated for the same period. Non-recurring costs are expected to primarily include pre-development evaluations, project planning and early development work, initial project financing costs, and site maintenance requirements.

**ITEM 3. LEGAL PROCEEDINGS.**

Information regarding legal proceedings is contained in Note 8 of the Consolidated Financial Statements contained in this report and is incorporated herein by reference.

**ITEM 4. MINE SAFETY DISCLOSURES.**

We consider health, safety, and environmental stewardship to be a core value of the Company.

**Exchange Controls**

There are no governmental laws, decrees or regulations in Canada that restrict the export or import of capital, including foreign exchange controls, or that affect the remittance of dividends, interest, or other payments to non-resident holders of the securities of Vista, other than Canadian withholding tax. See "Certain Canadian Federal Income Tax Considerations for U.S. Residents" below.

**Certain Canadian Federal Income Tax Considerations for U.S. Residents**

The following summarizes certain Canadian federal income tax consequences generally applicable under the *Income Tax Act* (Canada) and the regulations enacted thereunder (collectively, the "Canadian Tax Act") and the *Canada-United States Income Tax Convention (1980)* (the "Convention") to the holding and disposition of Common Shares.

Comment is restricted to holders of Common Shares each of whom, at all material times for the purposes of the Canadian Tax Act and the Convention:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) is resident solely in the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) is entitled to the benefits of the Convention;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) holds all Common Shares as capital property;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) holds no Common Shares that are "taxable Canadian property" (as defined in the Canadian Tax Act) of the holder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) deals at arm's length with and is not affiliated with Vista;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) does not and is not deemed to use or hold any Common Shares in a business carried on in Canada; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) is not an insurer that carries on business in Canada and elsewhere;

(each such holder, a "U.S. Resident Holder").

Certain U.S.-resident entities that are fiscally transparent for United States federal income tax purposes (including limited liability companies) are generally not themselves entitled to the benefits of the Convention. However, members of, or holders of, an interest in such entities that hold Common Shares may be entitled to the benefits of the Convention for income derived through such entities. Such members or holders should consult their own tax advisors in this regard.

[**Table of Contents**](#Toc)

Generally, a holder's Common Shares will be considered to be capital property of the holder provided that the holder is not a trader or dealer in securities, did not acquire, hold or dispose of the Common Shares in one or more transactions considered to be an adventure or concern in the nature of trade and does not hold the Common Shares as inventory in the course of carrying on a business.

Generally, a holder's Common Shares will not be "taxable Canadian property" of the holder at a particular time at which the Common Shares are listed on a "designated stock exchange" (which currently includes the TSX) unless both of the following conditions are met at any time during the 60-month period ending at the particular time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the holder, persons with whom the holder does not deal at arm's length, or any partnership in which the holder or persons with whom the holder did not deal at arm's length holds a membership interest directly or indirectly through one or more partnerships, alone or in any combination, owned 25% or more of the issued shares of any class of the capital stock of Vista; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) more than 50% of the fair market value of the Common Shares was derived directly or indirectly from, or from any combination of, real or immovable property situated in Canada, "Canadian resource properties" (as defined in the Canadian Tax Act), "timber resource properties" (as defined in the Canadian Tax Act), or options in respect of or interests in such properties.

In certain other circumstances, a Common Share may be deemed to be "taxable Canadian property" for purposes of the Canadian Tax Act.

This summary is based on the current provisions of the Canadian Tax Act and the Convention in effect on the date hereof, all specific proposals to amend the Canadian Tax Act and Convention publicly announced by or on behalf of the Minister of Finance (Canada) on or before the date hereof, and the current published administrative and assessing policies of the CRA. It is assumed that all such amendments will be enacted as currently proposed, and that there will be no other material change to any applicable law or administrative or assessing practice, although no assurance can be given in these respects. Except as otherwise expressly provided, this summary does not take into account any provincial, territorial or foreign tax considerations, which may differ materially from those set out herein.

***This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be and should not be construed as legal or tax advice to any particular U.S. Resident Holder. U.S. Resident Holders are urged to consult their own tax advisers for advice with respect to their particular circumstances. The discussion below is qualified accordingly.***

A U.S. Resident Holder who disposes or is deemed to dispose of one or more Common Shares generally should not thereby incur any liability for Canadian federal income tax in respect of any capital gain arising as a consequence of the disposition.

A U.S. Resident Holder to whom Vista pays or is deemed to pay a dividend on the holder's Common Shares will be subject to Canadian withholding tax, and Vista will be required to withhold the tax from the dividend and remit it to the CRA for the holder's account. The rate of withholding tax under the Canadian Tax Act is 25% of the gross amount of the dividend (subject to reduction under the provisions of an applicable tax treaty). Under the Convention, a U.S. Resident Holder who beneficially owns the dividend will generally be subject to Canadian withholding tax at the rate of 15 % (or 5%, if the U.S. Resident Holder who beneficially owns the dividend is a company that is not fiscally transparent and which owns at least 10% of the voting stock of Vista) of the gross amount of the dividend.

**Certain United States Federal Income Tax Considerations for U.S. Residents**

There may be material tax consequences to U.S. Residents in relation to an acquisition or disposition of Common Shares or other securities of the Company. U.S. Residents should consult their own legal, accounting and tax advisors regarding such tax consequences under United States, state, local or foreign tax law regarding the acquisition or disposition of our Common Shares or other securities, in particular, the tax consequences of the Company possibly being a PFIC within the meaning of Section 1297 of the United States *Internal Revenue Code.* See the section "Item 1A. – Risk Factors – The Company is possibly a "passive foreign investment company," which would likely have adverse U.S. federal income tax consequences for U.S. shareholders" above.

[**Table of Contents**](#Toc)

**Unregistered Sales of Equity Securities**

None.

**Repurchase of Securities**

During 2025, neither Vista nor any affiliate of Vista repurchased Common Shares of Vista registered under Section 12 of the Exchange Act.

**NYSE American Corporate Governance**

Section 110 of the NYSE American Company Guide permits the NYSE American to consider the laws, customs and practices of foreign issuers in relaxing certain NYSE American listing criteria, and to grant exemptions from NYSE American listing criteria based on these considerations. A company seeking relief under these provisions is required to provide written certification from independent local counsel that the non-complying practice is not prohibited by home country law. A description of the significant ways in which the Company's governance practices differ from those followed by domestic companies pursuant to NYSE American standards is as follows:

*Shareholder Meeting Quorum Requirement:* The NYSE American minimum quorum requirement for a shareholder meeting is one-third of the outstanding shares of common stock. In addition, a company listed on the NYSE American is required to state its quorum requirement in its bylaws. The Company's quorum requirement is set forth in its Articles under the laws of the Province of British Columbia, Canada. Under the Company's Articles, the quorum for the transaction of business at the meeting is two or more shareholders entitled to vote at the meeting represented in person or by proxy.

The foregoing is consistent with the laws, customs and practices in Canada.

**ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.**

*The following discussion and analysis should be read in conjunction with our consolidated financial statements for the two years ended December 31, 2025 and 2024, 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 that involve risks, uncertainties, and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including, but not limited to, those set forth under the section heading "Item 1A. Risk Factors" above and elsewhere in this annual report on Form 10-K. See section heading "Note Regarding Forward-Looking Statements" in this annual report on Form 10-K.*

**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.

[**Table of Contents**](#Toc)

Our flagship asset is the Mt Todd Gold Project ("Mt Todd" or the "Project"), a development-stage gold deposit located in the Tier-1 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 "Mt Todd FS" or the "Study"). The Mt Todd FS significantly decreased the initial capital requirement, 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 Mt Todd 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 Mt Todd 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

&nbsp;&nbsp;&nbsp;&nbsp;● 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

&nbsp;&nbsp;&nbsp;&nbsp;● 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

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"). The 2024 FS evaluated the development of a 50,000 tpd, nominally 17.75 million tpa, operation.

In January 2026, the Company announced continued progress at its Mt Todd gold project and outlined the pathway to initiate detailed engineering and design in 2027. The Company would expect this milestone to initiate a period of approximately 27-months for design, construction, and commissioning.

Our focus for 2026 is on establishing the foundation for the successful execution of the Mt Todd project. Priorities include obtaining permit modifications to align existing approved permits with the Mt Todd FS; expanding corporate capability by building an Australia-based team to lead project development; and addressing recommendations presented in the Mt Todd FS that will provide key inputs for detailed engineering and design. On March 9, 2026, Vista closed a public offering for aggregate gross proceeds totaling $44,850 to fund these priorities and other general corporate purposes.

We have commenced efforts to obtain permit modifications and are actively engaged with consultants, regulators, and stakeholders. Some modifications have already been submitted, and programs to support other submissions have been planned and are expected to begin within the coming weeks. We anticipate the approval of these modifications will be achieved in 2027.

We are addressing recommendations presented in the Mt Todd FS. Recent drilling has provided core for selective metallurgical testing to confirm grind size, gold recoveries, and optimal selection and sizing of equipment in the process plant. A geotechnical review is also underway, with planned drilling around the Batman pit to assess the opportunity to steepen the west pit wall, reduce stripping, and potentially convert additional mineral resources to mineral reserves.

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***

Consolidated net loss for the year ended December 31, 2025 was $7,499 or $0.06 per common share in the capital of Vista (each, a "Common Share") on both a basic and diluted basis. Consolidated net income for the year ended December 31, 2024 was $11,249 or $0.09 per Common Share on both a basic and diluted basis. The principal components of our 2025 net loss and the year-over-year changes are discussed below.

The Company had cash of $13,622, working capital of $13,057, and no debt as of December 31, 2025.

[**Table of Contents**](#Toc)

***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, including fixed costs, project programs, and non-cash stock-based compensation, were $5,593 and $3,458 during the years ended December 31, 2025 and 2024, respectively. These costs comprised fixed costs and project program costs at Mt Todd.

For the years ended December 31, 2025 and 2024, our fixed exploration, property evaluation and holding costs totaled $3,319 and $2,921, respectively. These costs included expenditures necessary to preserve our property rights and meet our safety, regulatory, and environmental responsibilities. The increase in 2025 included expenses related to greater focus by corporate personnel on site-related projects.

Expenses incurred for 2025 project programs at Mt Todd totaled $2,274, including $1,963 for the Mt Todd FS. Expenses incurred for 2024 Mt Todd project programs totaled $537, including $408 for various technical studies.

Included in the 2025 and 2024 exploration, property evaluation and holding costs were non-cash stock-based compensation of $218 and $182, respectively.

***Corporate Administration***

Corporate administration costs were $3,611 and $3,663 during the years ended December 31, 2025 and 2024, respectively. The 2025 and 2024 corporate administration costs included non-cash stock-based compensation of $453 and $502, respectively. The total expenses in the comparable periods were substantially unchanged.

***Gain on sale of plant and equipment***

There were no sales of plant and equipment during 2025. In March 2024, the Company recorded a gain of $802 upon sale of certain components of our used mill equipment. Gross proceeds totaled $900, partially offset by selling expense of $98.

***Non-Operating Income and Expenses***

*Interest Income*

Interest income was $573 and $701 during the years ended December 31, 2025 and 2024, respectively. The decrease in 2025 was due to a decrease in the average interest rate applicable to invested cash balances.

*Other Income*

Other Income was $1,220 and $13 for the years ended December 31, 2025 and 2024, respectively. The increase in the comparable twelve-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 $6,614 and $5,735 for the years ended December 31, 2025 and 2024, respectively. The increase in operating cash outflows largely resulted from 2025 expenditures for the Mt Todd FS being expensed while costs of the 2024 drilling program were recorded as capitalized development costs and included in investing activities, partially offset by other income and sources of cash resulting from changes in working capital.

***Investing Activities***

Net cash provided by (used in) investing activities was ($742) and $15,593 for the years ended December 31, 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 $1,715 in 2025 because substantially all 2024 drilling costs were capitalized as development costs while the Mt Todd FS costs were expensed and included as cash used in operating activities. Cash used in investing activities for purchases of plant and equipment was higher by $248 in 2025 primarily due to installation of an enhanced evaporation system.

***Financing Activities***

Net cash of $4,028 for the year ended December 31, 2025 was provided by financing activities. These activities include receipt of net proceeds of $4,296 under the ATM Program (as defined below) offset by payments of $268 for employee withholding taxes in lieu of issuing Common Shares earned from the vesting of restricted share unit awards.

Net cash of $1,023 for the year ended December 31, 2024 was provided by financing activities. These activities include receipt of net proceeds of $1,108 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 short-term investments to be its primary measure of liquidity. Our cash liquidity position as of December 31, 2025, comprising cash and cash equivalents of $13,622, reflected a net decrease of $3,328 during the year ended December 31, 2025.

Current assets, net of current liabilities ("Working Capital"), is a secondary measure of liquidity for the Company. The Company had Working Capital of $13,057 and $16,457 at December 31, 2025 and December 31, 2024, respectively. This represents a net decrease of $3,400 during the year ended December 31, 2025.

During the year ended December 31, 2025, the Company's primary sources of cash inflows were $4,296 from equity financing activity, receipt of $1,257 related to our recovery of certain tax amounts paid previously, and interest income of $573. These sources of cash were offset by operating cash outflows of $8,444 and other expenditures of $1,010. Recurring costs for corporate administration and Mt Todd maintenance, and spending on the Mt Todd FS and other project programs comprised most of the Company's operating cash outflows during the year ended December 31, 2025. Of the other expenditures, $592 related to additions of plant and equipment and $150 related to developing revised mineral resources estimates for Mt Todd that incorporated drilling results produced after the previous mineral resources estimates. Additional details regarding 2025 financial results are presented in the "Results from Operations" section above and the preceding discussions in this section regarding operating activities, investing activities, and financing activities.

For the 12-month period following December 31, 2025, the Company estimates, before consideration of the use of proceeds discussed below, net recurring expenditures will be approximately $8,700, plus $1,800 for non-recurring project program costs. Management expects to fund Vista's activities during the next twelve months from existing Working Capital and additional Working Capital available from the offering of Common Shares discussed below.

[**Table of Contents**](#Toc)

On March 9, 2026, Vista closed a public offering of 17,940,000 Common Shares, inclusive of the underwriters' exercise of their 15% overallotment option, at a price of $2.50 per Common Share (the "Offering"). Aggregate gross proceeds from the Offering totaled $44,850. After deductions for underwriting discounts, commissions and other costs, net proceeds are estimated to total $41,900. We intend to use the net proceeds to advance exploration and development activities at our Mt Todd gold project and for general corporate purposes, including:

---

| | |
|:---|:---|
| **Description of Use of Proceeds** | **Use of Proceeds** |
| Pre-Development Evaluations at Mt Todd | $6700 |
| Increase in Organizational Capacity | $3500 |
| Professional Fees and Project Financing Costs | $4200 |
| Project Planning and Early Development Works | $3200 |
| Working Capital & General Corporate Purposes | $24300 |
| Net Proceeds of the Offering | $41900 |

---

We are a party to an at-the-market offering agreement (the "ATM Agreement") with H. C. Wainwright & Co., LLC ("Wainwright"). Under the ATM Agreement, the Company can, but is not obligated to, issue and sell Common Shares through Wainwright (the "ATM Program"). In connection with the Offering, we suspended the ATM Agreement and terminated the continuous offering by us under the associated prospectus supplement. We will not make any sales of our common shares pursuant to the ATM Agreement unless and until a new prospectus supplement is filed; however, the ATM Agreement remains in full force and effect. During the year ended December 31, 2025, the Company issued 2,813,888 Common Shares under the ATM Program for net proceeds of $4,296.

Other potential sources of cash inflows may include issuances of Common Shares, monetization of Vista's remaining non-core assets, which include royalty interests on properties in the U.S., a royalty interest on a property in Canada, and used mill equipment that is being marketed by a third-party mining equipment dealer.

We believe our Working Capital as of December 31, 2025, together with the net proceeds from the Offering, interest income, other potential future sources of financing, and sales of non-core assets, will be sufficient to fund our currently planned corporate expenses, Mt Todd holding costs, and other anticipated Mt Todd programs for at least one year from the date of issuance of this annual report on Form 10-K.

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 find other means of financing. Vista also considers possible corporate opportunities as a means to enhance our liquidity. The underlying value and recoverability of the amounts shown as mineral properties and plant and equipment as presented in our Consolidated Balance Sheet at December 31, 2025 depends 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 required to be disclosed in this annual report on Form 10-K.

**Critical Accounting Estimates and Recent Accounting Pronouncements**

***Critical Accounting Estimates***

Critical accounting estimates are accounting estimates that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on the financial condition or results of operations of the Company. Management has identified the following critical accounting estimates. See Note 2 to our consolidated financial statements contained in "Part II. Item 8. Financial Statements and Supplementary Data" for additional accounting policies and estimates.

*Impairment Assessment of Long-Lived Assets*

Our long-lived assets are evaluated for impairment when information becomes available indicating that the carrying value may not be recoverable. Assumptions and estimates considered in valuing our mineral properties included management's expectations for the price of gold, foreign exchange rates, costs to build and operate the mine, and projected cash flows. These assumptions are subjective and subject to a range of uncertainties. A feasibility study reduces the uncertainty around some assumptions to an acceptable level and is a primary source of evidence.

*Income Taxes*

We have assets, hold interests, and conduct activities in several countries and are subject to their tax regimes. Tax laws are complex and continue to evolve. While we have a history of losses, our assumptions made in tax returns are subject to review and interpretation by taxing authorities and could be modified. Our critical tax estimates include timing of future income, deductibility of expenses, sustainability of tax positions, valuation allowances on deferred tax assets, and allocation of expenses between companies.

***Recent Accounting Pronouncements***

See Note 2 to our consolidated financial statements contained in "Part II. Item 8. Financial Statements and Supplementary Data" for recent accounting pronouncements applicable to the Company.

**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.

[**Table of Contents**](#Toc)

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.

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 includes the following financial measures presented on a non-U.S. GAAP basis:

● Cash Costs per ounce produced and per tonne processed;

● AISC per ounce;

● Capital Efficiency; and

● Benefit to Cost Ratio.

Cash Costs per ounce produced and AISC per ounce 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 of gold produced 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<sub>5%</sub> of project cash flows divided by initial capital.

The following table presents the calculations used to determine the non-U.S. GAAP financial measures presented in the report.

**ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.**

***Management's Report on Internal Control Over Financial Reporting***

The management of Vista Gold Corp. and its subsidiaries (collectively, "Vista," the "Company," "we," "our," or "us") is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed by, or under the supervision of, the Company's principal executive and principal financial officers and the Company's board of directors (the "Board of Directors"), and effected by management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are also subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company's management assessed the effectiveness of the Company's internal control over financial reporting at December 31, 2025. In making this assessment, the Company's management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission Internal Control-Integrated Framework in 2013. Based upon its assessment, management concluded that, at December 31, 2025, the Company's internal control over financial reporting was effective.

***Report of Independent Registered Public Accounting Firm***

To the Shareholders and Board of Directors of Vista Gold Corp.

***Opinion on the Consolidated Financial Statements***

We have audited the accompanying consolidated balance sheets of Vista Gold Corp. (the "Company"), as of December 31, 2025 and 2024, and the related consolidated statements of income (loss), shareholders' equity, and cash flows for the years ended December 31, 2025, and 2024 and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of Vista Gold Corp. as of December 31, 2025 and 2024, and the results of its operations and its cash flows for the years ended December 31 2025, and 2024 in conformity with accounting principles generally accepted in the United States of America.

***Basis for Opinion***

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatements of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

***Critical Audit Matters***

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We have determined that there are no critical audit matters.

We have served as the Company's auditor since 2023.

Supplemental cash flow information (Note 9)

**VISTA GOLD CORP.**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(Dollar amounts in U.S. dollars and in thousands, except shares and per share data)**

**1. *Nature of Operations***

Vista Gold Corp. and its subsidiaries operate as a development-stage company in the gold mining industry. The Company's flagship asset is the Mt Todd gold project ("Mt Todd" or the "Project") in Northern Territory, Australia. We are taking steps to ensure that development can proceed in an orderly and efficient manner. Since acquiring Mt Todd in 2006, we have invested substantial financial resources to systematically explore, evaluate, engineer, permit, and de-risk the Project. We do not currently generate recurring positive cash flows from mining operations.

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

**2. *Significant Accounting Policies and Estimates***

*Principles of Consolidation*

The Consolidated Financial Statements include the accounts of Vista and its subsidiaries, all of which are 100%-owned subsidiaries, either directly or indirectly through a subsidiary, and under Vista's control. All significant intercompany balances and transactions have been eliminated. The Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States.

*Use of Estimates*

Preparation of the Company's Consolidated Financial Statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income, and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions are: gain recognition; asset impairments; capitalization of development costs; valuation allowances for deferred tax assets; uncertain tax positions; the fair value and accounting treatment of stock-based compensation; functional currency; and the provision for environmental liabilities. Management based its estimates on historical experience, evaluation of pertinent circumstances, and various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results will likely differ from amounts estimated in these consolidated financial statements.

*Cash and Cash Equivalents*

Cash and cash equivalents include cash on hand and government securities with original maturities of 90 days or less when purchased.

*Foreign Currency Transactions*

Our functional currency is the U.S. dollar. Foreign currency transactions denominated in a currency other than the functional currency are recorded at the approximate rate of exchange at the transaction date and any gains/(losses) resulting therefrom are recorded in other expense. For each of the years ended December 31, 2025 and 2024, net foreign currency gains/(losses) were insignificant.

 

*Mineral Properties*

Mineral property acquisition costs, including directly related costs, are capitalized when incurred. After acquisition of a mineral property, associated exploration and evaluation costs are charged to expense as incurred until mineral reserves reported in accordance with Item 1300 of Regulation S-K under the Securities Exchange Act of 1934, as amended, are established and the Company deems development activities to have commenced. Drilling and related costs are capitalized for an ore body where proven and probable mineral reserves exist, and the activities are directed at obtaining additional information about the ore body or converting measured, indicated, and inferred mineral resources to proven and probable mineral reserves. All other drilling and related costs are expensed as incurred.

[**Table of Contents**](#Toc)

Capitalized costs associated with a mineral property will be amortized using the units-of-production method over the estimated life of mineral reserves once sustainable production is achieved. If mineral properties are sold or abandoned, any unamortized costs will be charged to expense in that period.

The recoverability of the carrying values of our mineral properties is dependent upon economic reserves being discovered or developed on the properties, permitting, financing, start-up, and profitable commercial production from, or the sale/lease of, or other strategic transactions related to these properties. Development and/or operation of mineral properties will depend on, among other things, management's ability to raise sufficient capital for these purposes. Gains on disposal and grant of royalty interests are recognized in operating income when the Company has completed its significant obligations.

We assess the carrying value of mineral properties for impairment whenever information or circumstances indicate the potential for impairment. Such evaluations compare estimated future net cash flows with our carrying costs and future obligations on an undiscounted basis. If it is determined that the estimated future undiscounted cash flows are less than the carrying value of the property, a write-down to the estimated fair value will then be reported in our Consolidated Statement of Income/(Loss) for the period.

*Impairment* 

Carrying values of long-lived assets, other than mineral properties, are evaluated for impairment when information becomes available that indicates the carrying value may not be recoverable. If it is determined that the fair value is less than the carrying value an impairment charge equal to the difference between the fair value and the carrying value will be recorded in our Consolidated Statements of Income/(Loss).

*Stock-Based Compensation*

Under our stock option, long-term incentive, and deferred share unit plans, the Company can grant stock incentive options, restricted share units, and deferred share units to executives, employees, consultants, and non-employee directors as applicable. Compensation expense for such grants is recorded in the Consolidated Statements of Income/(Loss) as a component of exploration, property evaluation and holding costs and corporate administration, with a corresponding increase to Common Shares in the Consolidated Balance Sheets. The fair value of option grants is calculated using the Black-Scholes option pricing model. The fair value of restricted and deferred share units is based on the closing price of our Common Shares on the grant date, or, in certain cases, amounts determined by a Brownian motion pricing model. The expense is based on the fair value of the grant on the grant date and is recognized over the vesting period specified for each grant. Forfeitures of unvested awards for all stock-based compensation result in expense reversal upon forfeiture.

*Accounting for Income Taxes*

We account for income taxes by recognizing deferred tax assets and liabilities for differences between the financial statement and tax bases of assets and liabilities at enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in enacted tax rates are recognized in the period that includes the enactment date. Valuation allowances are recorded to reduce deferred tax assets to net amounts estimated to be more likely than not of being realized.

The Company evaluates its income tax positions and recognizes a liability for uncertain tax positions that are not more likely than not to be sustained by tax authorities. If the Company were to determine that uncertain tax positions meet the criteria for recognition, an estimated liability and related interest and penalties would be recognized as income tax expense.

*Fair Value of Financial Instruments*

Our financial instruments include cash and cash equivalents, accounts payable, and certain other current assets and liabilities. Due to the short-term nature of these financial instruments, carrying amounts approximate fair value.

[**Table of Contents**](#Toc)

*Recently Adopted Accounting Standards*

In 2025, we adopted ASU 2023-09, *Income Taxes (Topic 740): Improvements to Income Tax Disclosures* ("ASU 2023-09"). ASU 2023-09 updates income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in ASU 2023-09 are effective for the Company for annual periods beginning after December 15, 2024. Certain prior period amounts presented in Note 10 have been restated within the tables to conform with the current period presentation. There was no change to the Consolidated Balance Sheets, Consolidated Statements of Income/(Loss), Consolidated Statements of Shareholders' Equity, and Statements of Cash Flows from the reclassifications. The adoption of ASU 2023-09 has not had a material effect on the Company's disclosures.

*Recently Issued Accounting Pronouncements Not Yet Adopted*

In November 2024, FASB issued ASU 2024-03, *Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses* ("ASU 2024-03"). ASU 2024-03 requires all public entities to disclose disaggregated information about purchases of inventory, employee compensation, depreciation, intangible asset amortization, and depletion for each income statement line item that contains those expenses. The amendments in ASU 2024-03 are effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. ASU 2024-03 allows for early adoption and requires either prospective adoption to financial statements issued for reporting periods after the effective date of ASU 2024-03 or retrospective adoption for any or all prior periods presented in the financial statements. The Company is currently assessing the impact of adopting ASU 2024-03 on the consolidated financial statements and related disclosures.

**3. *Mineral Properties***

*Mt Todd, Northern Territory, Australia*

Capitalized mineral property values were:

---

| | | |
|:---|:---|:---|
|  | **At December 31, 2025** | **At December 31, 2024** |
| Mt Todd, Australia  | $1070 | $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.

Drilling and related costs are capitalized for an ore body where proven and probable mineral reserves exist, and the activities are directed at obtaining additional information about the ore body or converting measured, indicated, and inferred mineral resources to proven and probable mineral reserves. All other drilling and related costs are expensed as incurred. Capitalized mineral property development drilling costs totaled $150 in the year ended December 31, 2025. Capitalized mineral property development drilling costs totaled $1,865 in the year ended December 31, 2024. 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. *Deferred 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 agreed to provide Vista with $20,000 cash 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"). 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.

The Royalty Agreement provided for Vista Gold Australia to receive a total of $20,000 in three installments, all of which were received by Vista prior to June 30, 2024. 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 comprises previously deferred 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.

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 through Wainwright (the "ATM Program"). The ATM Agreement was refreshed in November 2024 to allow for aggregate sales proceeds of up to $8,000. No securities can be offered in Canada under the ATM Agreement. As of December 31, 2025, $3,379 remained available under the ATM Program.

During the year ended December 31, 2025 the Company sold 2,813,888 Common Shares for net proceeds of $4,926 under the ATM Program. During the year ended December 31, 2024 the Company sold 1,722,966 Common Shares for net

[**Table of Contents**](#Toc)

proceeds of $1,108 under the ATM Program. Each sale under the ATM Agreement was made pursuant to an "at the market offering" as defined in Rule 415 under the United States Securities Act of 1933, as amended. See Note 12 for a subsequent event.

**Other Share Issuances**

During the years ended December 31, 2025 and 2024, we issued 641,621 and 445,551 Common Shares, respectively, in connection with vesting of restricted share units ("RSUs"). During the years ended December 31, 2025 and 2024, we issued nil and 295,000 Common Shares, respectively, in exchange for deferred share units ("DSUs") held by directors of the Company whose service on the Board of Directors ended in those years.

**Warrants**

Warrant activity is summarized in the following table.

All warrants expired on July 12, 2024.

**Stock-Based Compensation**

The Company's stock-based compensation plans include: RSUs currently outstanding under the Company's long-term equity incentive plan ("LTIP"), DSUs issuable pursuant to the Company's deferred share unit plan ("DSU Plan") and stock options ("Stock Options") issuable under the Company's stock option plan. 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 one time. Stock-based compensation may be granted from time to time at the discretion of the Board of Directors of the Company (the "Board of Directors"), with vesting provisions as determined by the Board of Directors.

Stock-based compensation expense for the years ended December 31, 2025 and 2024 was:

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31,**  | **Year Ended December 31,**  |

| RSUs | $420 | $391 |
| DSUs | 251 | 293 |
|  | $671 | $684 |

---

As of December 31, 2025, unrecognized compensation expense for awarded RSUs was $283, which is expected to be recognized over a weighted average period of 1.2 years.

| Vested | (959921) | 0.39 |
| Unvested - December 31, 2025 | 2491669 | $0.33 |

---

During the years ended December 31, 2025 and 2024, the Company withheld shares equivalent to the value of employee withholding taxes in lieu of issuing Common Shares which resulted from RSUs vesting in the period.

Under the LTIP, a portion of the RSU awards vest on a fixed future date providing the recipient continues to be affiliated with Vista on that date. Other RSU awards vest subject to achievement of certain performance and market criteria, including the accomplishment of certain corporate objectives and the Company's share price performance. Of the unvested RSUs, approximately 28% will vest based on fixed future dates, and approximately 72% will vest on share-price criteria. The minimum vesting period for RSUs is one year.

*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 after the non-employee director ceases to be a director of the Company. During the year ended December 31, 2025, the Board of Directors granted 364,000 DSUs and the Company recognized $251 of DSU expense. During the year ended December 31, 2024, the Board of Directors granted 767,000 DSUs and the Company recognized $293 of DSU expense.

| Effect of dilutive stock-based awards |  | 3,413,294 |
| Diluted Common Shares | 125,164,651 | 125,611,300 |

---

As the Company was in a net loss position for the year ended December 31, 2025, all potentially dilutive Common Shares were considered antidilutive.

Unvested RSUs representing 108,668 Common Shares, Stock Options to purchase 350,000 Common Shares, and warrants to purchase 7,408,101 Common Shares were outstanding during part of the year ended December 31, 2024 but were not included in the computation of diluted weighted average Common Shares outstanding because their effect would have been anti-dilutive.

**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

[**Table of Contents**](#Toc)

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. *Supplemental Cash Flow Information and Material Non-Cash Transactions***

As of December 31, 2025 and 2024, all cash and cash equivalents were held as liquid bank deposits and/or government instruments in the United States or Australia.

There were no significant non-cash transactions for the years ended December 31, 2025 and 2024.

**10. *Income Taxes***

The Company's income/(loss) before provision for income taxes consisted of the following:

---

| | | |
|:---|:---|:---|
|  | **Years Ended December 31,** | **Years Ended December 31,** |
|  | **2025** | **2024** |
| U.S.  | $(23) | $(64) |
| Foreign | (7476) | 11313 |
|  | $(7499) | $11249 |

---

During the years ended December 31, 2025 and 2024, the Company recognized $nil current and deferred income tax expense or benefit in each of the U.S. and foreign jurisdictions, due to full valuation allowances within each jurisdiction.

*Deferred Taxes*

Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and (b) operating losses and tax credit carryforwards. The tax effects of significant items comprising the Company's deferred taxes are as follows:

---

| | | |
|:---|:---|:---|
|  | **December 31,** | **December 31,** |
|  | **2025** | **2024** |
| Deferred income tax assets: |  |  |
| Net operating loss carryforwards | $46618 | $41440 |
| Accrued compensation | 81 | 24 |
| Stock compensation | 15 | 33 |
| Capital loss carryforwards | 14956 | 14954 |
| Property, plant and equipment | 6879 | 6924 |
| Capital expenditures | 366 | 366 |
| VAT recoverable |  | 144 |
| Unrealized foreign exchange gain/loss | 16 | 6 |
| Offering costs | 64 | 104 |

| Valuation allowance for future tax assets | (62995) | (57995) |
| Total deferred taxes, net | $— | $— |

*Valuation Allowance on Deferred Tax Assets*

ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is "more likely than not." Realization of the future tax benefits is dependent on the Company's ability to generate sufficient taxable income within the carryforward period. Because of the Company's recent history of operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has provided a valuation allowance. The valuation allowance increased by 5,000 during 2025.

*Loss Carryforwards*

Net operating and capital loss carryforwards as of the December 31, 2025 are as follows:

---

| | | |
|:---|:---|:---|
|  | **Amount** | **Expiration Years** |
| Net operating losses, Federal (Pre January 1, 2018) | $14854 | 2030 - 2037 |

| Capital loss carryforwards, foreign | 110786 | Do not expire |

*Tax Statute of Limitations*

The Company files income tax returns in Canada, U.S. federal and state jurisdictions, and other foreign jurisdictions. There are currently no tax examinations underway for these jurisdictions. Furthermore, the Company is no longer subject to Canadian tax examinations by the Canadian Revenue Agency for years ended on or before December 31, 2021 or U.S. federal income tax examinations by the Internal Revenue Service for years ended on or before December 31, 2021. Some U.S. state and other foreign jurisdictions are still subject to tax examination for years ended on or before December 31, 2020.

Although certain tax years are closed under the statute of limitations, tax authorities can still adjust losses being carried forward to open years. See Note 8 for discussion of ongoing legal matters associated with an assessment by the SAT.

**11. *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 from mining operations during the years ended December 31, 2025 or 2024. The geographic location of mineral properties and plant and equipment is provided in Notes 3 and 4, respectively.

VISTA GOLD CORP.

INSIDER TRADING POLICY

(Adopted on December 19, 2003, as amended on March 2, 2009, March 5, 2013, March 5, 2017, July 28, 2020, March 5, 2023, and October 22, 2024)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. BACKGROUND AND PURPOSE

The federal securities laws of the United States and applicable securities laws in Canada prohibit any member of the Board of Directors (a "Director"), officer or other employee of Vista Gold Corp. or any of its affiliated entities (collectively, the "Company") from purchasing or selling Company securities on the basis of material non-public information concerning the Company, from disclosing material non-public information to others or from advising others how to trade when in possession of material non-public information. These laws impose severe sanctions on individuals who violate them. In addition, the United States Securities and Exchange Commission (the "SEC") has the authority to impose large fines on the Company and on the Company's Directors, executive officers and controlling stockholders if the Company's employees engage in insider trading and the Company has failed to take appropriate steps to prevent the insider trading. This liability is known as "controlling person" liability.

The goals of this insider trading policy ("Policy") are to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•prevent violations of insider trading laws;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•avoid conditions requiring proxy disclosure of reporting violations by persons subject to Section 16 of the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act") and avoid potential recoupment by the Company of any profit made on trades in violation of Section 16 of the Exchange Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•avoid even the appearance of impropriety on the part of those employed by, or associated with, the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•protect the Company from controlling person liability; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•protect the reputation of the Company, its Directors, its officers and its employees.

The Board of Directors will review this Insider Trading Policy periodically and update it as necessary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. PROHIBITION ON TRADING WHILE AWARE OF MATERIAL NON-PUBLIC INFORMATION; PROHIBITION ON TIPPING OTHERS

2.1 This Section 2 applies to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all officers of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all employees of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all family members of Directors, officers and employees of the Company who share the same address as, or are financially dependent on, the Director, officer or employee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all corporations, partnerships, trusts or other entities in which any of the above persons has a substantial beneficial interest, serves as a trustee (or similar capacity) or is otherwise owned or controlled by any of the above persons.

2.2 No person covered by this Section 2 may:

Prohibited Transactions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•purchase or sell, or enter into a transaction involving, any securities of the Company or a related financial instrument while he or she is aware of any material non-public information concerning the Company or engage in any other action to take personal advantage of that information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•purchase or sell any securities of another company while he or she is aware of any material non-public information concerning such other company which he or she learned in connection with his, her or another person's service as a Director, officer or employee of the Company;

Prohibited Communications

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•disclose to any other person, including family, friends or acquaintances, any material non-public information concerning the Company, except in the necessary course of business as required in the performance of his or her Company duties or as approved by the Chief Executive Officer ("CEO"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•disclose to any other person any material non-public information concerning another company which he or she learned in the course of his or her service as a Director or employee of the Company, except in the necessary course of business as required in the performance of his or her Company duties or as approved by the CEO.

Vista Gold Corp.

Insider Trading Policy - October 2024

------

The meaning of communications "in the necessary course of business" will depend on the situation and would generally cover, but is not limited to, communications with:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•vendors, suppliers or strategic partners on issues such as research and

developments, sales and marketing and supply contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Directors, officers and employees, of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•lenders, legal counsel, auditors, underwriters, financial and other professional advisors to the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•parties to negotiations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•governmental agencies and non-governmental regulators.

Any such communication of material non-public information will only be made to parties that are subject to a confidentiality agreement or a fiduciary duty of confidentiality to the Company. Transactions that may be necessary or justifiable for independent reasons (such as the need to raise money for an emergency expenditure) are not excepted from this policy; if the person covered by this Section 2 has material, non-public information, the prohibition on transactions still applies.

In no case may any such communications be made under circumstances in which it is reasonably foreseeable that the recipient of the communication is likely to purchase or sell securities of the Company. Any questions concerning the above and as to whether communication of particular information is permissible should be referred to the CEO.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3The prohibition on purchases and sales of Company securities while aware of material non-public information concerning the Company applies whether or not a blackout period is then in effect (see Section 3 of this Policy), except that the prohibition does not apply to a transaction pursuant to a trading plan which complies with Section 3.4 of this Policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4Definitions of "Material Information" and "Non-Public Information"

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) <u>Material Information</u>. Material information is information (including a change in previous information or facts) that (i) results in or would reasonably be expected to result in a significant change in the market price or value of a company's securities; or (ii) would be considered important by a reasonable investor in making an investment decision. Material information can include positive or negative information and may include information concerning developing situations or a company's plans with respect to any of the below subjects. The determination of whether information is "material" is subjective and requires judgement. Examples of material information may include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•financial results;

This list is illustrative only and is not intended to provide a comprehensive list of circumstances that could give rise to material information. If you have any question as to whether particular information is material, consult with the CEO, who will consult with legal counsel as appropriate.

<u>Non-Public Information.</u> Information concerning the Company or another company is considered non-public if it has not been disseminated in a manner making it available to investors generally. To avoid the appearance of impropriety, as a general rule, information should not be considered fully absorbed by the marketplace until after the end of the first full business day after the information is released. If, for example, the Company were to make a pre-market announcement on a Monday, you are not permitted to trade in the Company's securities until the open of business on

Tuesday. If you have any question as to whether particular information has been generally disclosed, consult with the CEO, who will consult with legal counsel as appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. BLACKOUT PERIODS

3.1 This Section 3 applies to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all officers of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all employees of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all family members of Directors, officers and -employees of the Company who share the same address as, or are financially dependent on, the Director, officer or employee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all corporations, partnerships, trusts or other entities in which any of the above persons has a substantial beneficial interest, serves as a trustee (or similar capacity) or is otherwise owned or controlled by any of the above persons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.2 <u>Quarterly Blackout Periods</u>. To avoid even the appearance of trading while aware of material non-public information the following provisions apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Non-Independent Directors, Management Employees and Certain Employees</u>. Beginning on the first business day following the end of each fiscal quarter and ending one business day following the date of public disclosure of the Company's quarterly financial results, all non-independent Directors, officers, management employees, non-management employees involved in the preparation of the Company's financial results and others, including if applicable, independent Directors, with inside knowledge of the Company's quarterly financial results (e.g.

Directors on the audit committee and/or other Directors that review the Company's announcement of quarterly results) shall refrain from conducting transactions involving the purchase or sale of the Company's securities (other than pursuant to a trading plan that complies with Section 3.4 of this Policy).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Independent Directors and Non-Management Employees</u>. Beginning two calendar weeks prior to the regularly scheduled board meeting at which the Company's quarterly financial statements shall be approved and ending one business day following the date of public disclosure of the Company's quarterly financial results, all independent Directors without inside knowledge of the Company's quarterly financial results and non-management employees not involved in the preparation of quarterly financial statements and without inside knowledge of the Company's quarterly financial results shall refrain from conducting transactions

Vista Gold Corp.

Insider Trading Policy - October 2024

------

involving the purchase or sale of the Company's securities (other than pursuant to a trading plan that complies with Section 3.4 of this Policy).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.3<u>Event Specific Blackout Periods</u>. From time to time, an event may occur that is material to the Company and is known by only a few employees, officers or Directors. So long as the event remains material and non-public, Directors, officers, and such other employees as designated by the Company, may not trade in the Company's securities (other than pursuant to a trading plan that complies with Section 3.4 of this Policy) until one business day after such information becomes public or is no longer material to the Company. Unless the Company determines that a Company-wide blackout is prudent, in which case the Company may provide notice of a blackout covering all Directors, officers and employees of the Company (with or without an explanation for the reason of such blackout), the Company and its representatives will not announce the existence of an event-specific blackout to anyone other than those individuals who are aware of the event giving rise to the blackout. Any person made aware of the existence of an event-specific blackout should not disclose the existence of the blackout to any other person. Such persons may not be informed of the reason they may not trade. The failure of the Company to designate a person as being subject to an event-specific blackout will not relieve that person of the obligation not to trade while aware of material non-public information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4<u>Transactions Pursuant to a Pre-Arranged Trading Plan that Complies with SEC Rule 10b51 and Canadian securities laws</u>. The prohibition on purchases and sales of Company securities during blackout periods does not apply to purchases or sales made pursuant to a trading plan adopted in compliance with SEC Rule 10b5-1 and Canadian securities laws, which provides an affirmative defense to insider trading liability where securities are purchased or sold pursuant to a pre-arranged trading plan that meets certain requirements. A SEC Rule 10b5-1 trading plan must comply with all of the following requirements:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the trading plan must be in writing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the insider may enter into, renew, amend, modify or terminate the trading plan <u>only</u> at a time when the insider is not in possession of material non-public information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the insider may <u>not</u> enter into, renew, amend, modify or terminate the trading plan during a blackout period (as described above);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the insider may only have one trading plan at any time for open market purchases and sales of the Company's securities (this prohibition does not apply to transactions directly with the Company (e.g. through employee stock ownership plans or dividend re-investment plans) which are not executed on the open market and does not apply to plans solely authorizing an agent to sell only enough securities as are necessary to satisfy tax withholding obligations arising exclusively from the vesting of a compensatory award ("sell-to-cover" plans), provided that the insider is not permitted to exercise control over the timing of such sale);

Vista Gold Corp.

Insider Trading Policy - October 2024

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•in any 12-month period of time, the insider is limited to one "single-trade plan", meaning a plan designed to effect the open market purchase or sale of the total amount of securities subject to the plan as a single transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the trading plan must: (i) expressly specify the amounts, prices and dates at which securities are to be sold or purchased under the plan; (ii) include a written formula for determining the amounts, prices and dates at which securities are to be sold or purchased under the plan; and (iii) not permit the insider to exercise any subsequent influence over how, when or whether to effect sales or purchases under the plan (provided that any person who does exercise such influence pursuant to the plan must not have been aware of material non-public information when doing so);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the trading plan for officer or director must include a provision that the first transaction effected under the plan may not occur until the later of (a) 90 days after plan adoption, renewal, amendment or modification or (b) one business day after filing of the Company's next Form 10-Q or Form 10-K disclosing the Company's financial results for the quarter in which the plan was adopted or modified (subject to a maximum of 120 days after adoption, renewal, amendment or modification); provided however that modifications that do not alter the sale or purchase prices or ranges of the plan and do not otherwise result in the adoption or deemed adoption of a new plan, will not begin a new waiting period hereunder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the trading plan for persons subject to this Policy that are not officers and directors must include a provision that the first transaction effected under the plan may not occur until 30 days after plan adoption, renewal, amendment or modification; provided however that modifications that do not alter the sale or purchase prices or ranges of the plan and do not otherwise result in the adoption or deemed adoption of a new plan, will not begin a new waiting period hereunder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•transactions must be made strictly in accordance with the terms of the trading plan; the insider must not alter or deviate from the trading plan (whether by changing the amount, price or timing of the sale or purchase, or otherwise) and the insider must not enter into or alter a corresponding or hedging transaction or position with respect to the Company's securities subject to the plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the insider must pre-clear the trading plan, and any renewals, amendments, modifications or terminations of the trading plan, with the CEO, or with the chair of the Audit Committee in the case of the CEO;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•entering into, renewing, amending, modifying or terminating the trading plan must be done in good faith and not as part of a plan or scheme to evade the prohibitions of insider trading laws; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•at the time of entering into, renewing, amending, modifying or terminating the trading plan, directors and officers must certify in the plan that they (a) are not aware of any material non-public information about the Company or its securities

Vista Gold Corp.

Insider Trading Policy - October 2024

------

and (b) are adopting the plan in good faith and not as part of a plan or scheme to evade insider trading prohibitions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.5<u>Transactions Under Company Plans</u> 

The Company's prohibition on purchases and sales of Company securities during blackout periods includes, but is not limited to, the exercise of stock options, but does not apply to purchases of Company stock in employee stock purchase plans resulting from an employee's periodic contribution of money to the plan pursuant to the election the employee made at the time of enrollment in the plan (as of the date of this Policy's adoption, the Company does not have any such employee stock purchase plan, although it reserves the right to adopt one subsequently). This Policy does, however, apply to sales by employees of Company stock purchased pursuant to any such plan. This Policy also may apply generally to transactions involving Company employee plans that may be adopted or modified by the Company in the future.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.6 If a person is subject to the blackout periods imposed by this Policy and the person's employment or tenure as a Director terminates during a blackout period (or if the person otherwise leaves the employment of the Company or ceases to be a Director while in possession of material non-public information), such person will continue to be subject to this Policy, and specifically to the ongoing prohibitions against trading and against communications to outsiders of material non-public information, until the blackout period ends. The Company may institute stop-transfer instructions to its transfer agent in order to enforce this provision.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.7 The Directors of the Company will not approve the grant of stock options or other forms of equity-based compensation awards that are based on the market price of the Company's common shares at the time of grant during the period of any trading black-out.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.8 Notwithstanding the prohibitions contained in Sections 3.2 and 3.3, the CEO may in exceptional circumstances waive the prohibition contained in Sections 3.2 and 3.3 provided that the individual seeking the waiver does not have any undisclosed material information and that making such a waiver would not otherwise violate any applicable securities laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.PRIOR NOTICE OF SECURITIES TRANSACTIONS

4.1 This Section 4 applies to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all officers of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all senior management employees of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all family members of Directors, officers and senior management employees of the Company who share the same address as, or are financially dependent on, such

Insider Trading Policy - October 2024

------

Director, executive officer or employee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all corporations, partnerships, trusts or other entities in which any of the above persons has a substantial beneficial interest, serves as a trustee (or similar capacity) or is otherwise owned or controlled by any of the above persons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.2 No person covered by this Section 4 may make any purchase or sale of securities of the Company (including derivative securities) unless he or she notifies, and obtains preclearance from, the CEO prior to such purchase or sale. Any pre-clearance that has been granted will be valid only for five business days following the approval date unless terminated earlier by the CEO. If a transaction for which pre-clearance has been granted is not effected within such period, the transaction must be pre-cleared again. Promptly following execution of the purchase or sale, the person covered by this Section 4 should so notify the CEO or his designee to facilitate the Company's reminding such person of insider reporting obligations within two business days of the transaction (U.S. law) and five days of the transaction (Canadian law).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. OTHER PROHIBITIONS ON TRADING ACTIVITIES

5.1 This Section 5 applies to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all officers of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all management employees of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all family members of Directors, officers and management employees of the Company who share the same address as, or are financially dependent on, the Director and officers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all corporations, partnerships, trusts or other entities in which any of the above persons has a substantial beneficial interest, serves as a trustee (or similar capacity) or is otherwise owned or controlled by any of the above persons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2<u>Short Sales</u>. Short sales of the Company's securities evidence an expectation on the part of the seller that the securities will decline in value, and therefore signal to the market that the seller has no confidence in the Company or its short-term prospects. In addition, short sales may reduce the seller's incentive to improve the Company's performance. For these reasons, short sales of the Company's securities are prohibited by those to whom this Section 5 applies. In addition, Section 16(c) of the Exchange Act prohibits officers and Directors from engaging in short sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3<u>Publicly Traded Options on Company Stock</u>. A transaction in options is, in effect, a bet on the short-term movement of the Company's stock and therefore creates the appearance that the individual or entity is trading based on inside information. Transactions

Vista Gold Corp.

Insider Trading Policy - October 2024

------

in options also may focus the individual or entity's attention on short-term performance at the expense of the Company's long-term objectives. Accordingly, transactions including puts, calls or other derivative securities, on an exchange or in any other organized market, are prohibited by those to whom this Section 5 applies. Option positions arising from certain types of hedging transactions are governed by the section below captioned "Hedging Transactions."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.4<u>Hedging Transactions</u>. Certain forms of hedging or monetization transactions, such as zero-cost collars and forward sale contracts, allow an individual or entity to lock in much of the value of his or her stock holdings, often in exchange for all or part of the potential for upside appreciation in the stock. These transactions allow the individual or entity to continue to own the covered securities, but without the full risks and rewards of ownership. When that occurs, the individual or entity may no longer have the same objectives as the Company's other stockholders. The Company prohibits those to whom this Section 5 applies from engaging in such transactions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.5<u>Margin Accounts and Pledges</u>. Securities held in a margin account may be sold by the broker without the customer's consent if the customer fails to meet a margin call. Similarly, securities pledged (or hypothecated) as collateral for a loan may be sold in foreclosure if the borrower defaults on the loan. Because a margin sale or foreclosure sale may occur at a time when the pledgor is aware of material non-public information or otherwise is not permitted to trade in Company securities, those to whom this Section 5 applies are prohibited from holding Company securities in a margin account or pledging Company securities as collateral for a loan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.6<u>Short-term Trading</u>. Section 16(b) of the Exchange Act prohibits officers and Directors from engaging in transactions involving the purchase and sale or sale and purchase of the Company's securities within any six month period and requires officers and Directors to return any profits made from such purchase and sale or sale and purchase of the Company's securities during any such six-month period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.EXCEPTIONS

The provisions of this Policy shall not apply to any entity referred to in the fifth bullet of Section 2.1 above if and to the extent such entity adopts and implements policies and procedures reasonably acceptable to counsel for such entity and counsel for the Company that are: (i) designed to ensure that any material non-public information regarding the Company is isolated and not conveyed to investment professionals and/or other personnel that may be involved in any decision to buy, sell or hold any securities of, or relating to, the Company; and (ii) otherwise consistent with the purpose of this Policy. However, the prohibitions of Section 2.2 above will continue to apply to that entity irrespective of any policies that the entity may adopt.

Vista Gold Corp.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.PENALTIES FOR VIOLATION

Violation of any of the foregoing rules is grounds for disciplinary action by the Company, including termination of employment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.COMPANY ASSISTANCE AND EDUCATION

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.1 The Company shall take reasonable steps designed to ensure that all Directors, officers and employees of the Company are educated about, and periodically reminded of, the securities law restrictions and Company policies regarding insider trading. Directors, officers and employees shall be required to certify their understanding of, and intent to comply with, the Company's policies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.2 The Company shall provide reasonable assistance to all Directors and executive officers of the Company, as requested by such Directors and executive officers, in connection with the filing of Forms 3, 4 and 5 under Section 16 of the U.S. Securities Exchange Act of 1934 and the electronic filing of insider reports with the Canadian securities authorities pursuant to National Instrument 55-104 Insider Reporting Requirements and Exemptions. However, the ultimate responsibility, and liability, for timely filing remains with the Directors and executive officers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. MISCELLANEOUS

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.1 <u>Other Procedures</u>. The Company may change these procedures or adopt such other procedures in the future as the Company considers appropriate in order to carry out the purposes of this Policy or to comply with the applicable securities laws of the United States and/or Canada.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.2 <u>No Third Party Rights</u>. This Policy is not intended to create any rights in third parties with respect to any violation of its terms and also is not intended to create any legal liability for the Company or any employee, officer or Director beyond those for which they are already responsible under applicable securities laws of the United States and Canada.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.3 <u>Other Companies</u>. The prohibitions contained in this Policy with respect to insider trading, tipping and recommending trades in securities of the Company will also apply to Directors, officers and employees of the Company in relation to the securities of other companies in circumstances where such persons may be in possession of material undisclosed information relating to such companies obtained in the course of the Company's business. In these circumstances, information about other companies should be treated in the same way as comparable information relating to the Company.

This Policy is dated October 22, 2024 and supersedes any previous policies of the Company concerning insider trading.
