Notes:
1) Thomas L. Dyer, P.E., is the QP responsible for reporting the Batman Deposit Proven and Probable mineral reserves.
2) Batman deposit mineral reserves are reported using a 0.35 g Au/t cutoff grade and $1,800 per ounce gold price. A US$ 1,500/oz-Au pit shell was used.
3) Deepak Malhotra is the QP responsible for reporting the heap-leach pad mineral reserves.
4) Because all the heap-leach pad reserves are to be fed through the mill, these reserves are reported without a cutoff grade applied.
5) The mineral reserves point of reference is the point where material is fed into the mill.
6) The effective date of the mineral reserve estimates under the requirements of S-K 1300 is December 31, 2023. There have been no changes in the mineral reserve estimates since December 31, 2022 because the Company and the relevant qualified persons determined that the same material assumptions and criteria continued to apply as of December 31, 2023, including that the Company used a cutoff grade higher than the economic cutoff grade such that any intervening changes in the underlying economic assumptions were not material and did not require use of a cutoff grade greater than 0.35 g Au/t for mineral reserve estimation purposes.
7) The effective date of the mineral reserve estimates under the requirements of NI 43-101 is December 31, 2023.

About Vista Gold Corp.

Vista is a gold project developer. The Company’s flagship asset is Mt Todd, located in the mining friendly jurisdiction of Northern Territory, Australia. Situated approximately 250 km southeast of Darwin, Mt Todd is one of the largest development stage opportunities in Australia and demonstrates compelling economics. All major environmental and operating permits necessary to initiate development of Mt Todd are in place.

Mt Todd benefits from its location in a leading mining jurisdiction and offers opportunities to add value through growth of mineral reserves, alternative development strategies, and other de-risking activities.

Note Regarding Non-GAAP Financial Measures

In this press release, 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 such non-U.S. GAAP measures. Since these measures do not incorporate revenues, changes in working capital and non-operating cash costs, they are not necessarily indicative of potential operating profit or loss, or cash flow from operations as determined in accordance with U.S. GAAP.

The non-U.S. GAAP measures associated with Cash Operating Costs, Cash Costs, AISC and resulting per ounce metrics are not, and are not intended to be, presentations in accordance with U.S. GAAP. These metrics represent costs and unit-cost measured related to the Project.

We believe that these metrics help investors understand the economics of the Project. We present the non-U.S. GAAP financial measures for our Project in the tables below. Actual U.S. GAAP results may vary from the amounts disclosed in this news release. Other companies may calculate these measures differently.

Cash Operating Costs, Cash Costs, AISC and Respective Unit Cost Measures

Cash Operating Costs is a non-U.S. GAAP metric used by the Company to measure aggregate costs of operations that will generally be within the Company’s direct control. We believe this metric reflects the operating performance potential for Mt Todd for the mining, processing, administration, and sales functions. Contractual obligations for surface land rights (project royalties) are excluded from this metric.

Cash Costs and AISC are non-U.S. GAAP metrics developed by the World Gold Council to provide transparency into the costs associated with producing gold and provide a comparable standard. The Company reports Cash Costs and AISC on a per ounce basis because we believe this metric more completely reflects mining costs over the life of mine. Similar metrics are widely used in the gold mining industry as comparative benchmarks of performance.

Cash Operating Costs consist of Project operating costs and refining costs, and exclude royalties.

Cash Costs consist of Cash Operating Costs (as described above), plus royalties. The sum of these costs is divided by the corresponding payable gold ounces to determine the per ounce metrics.

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

Other costs excluded from Cash Operating Costs, Cash Costs, and AISC include depreciation and amortization, income taxes, government royalties, financing charges, costs related to business combinations, asset acquisitions other than sustaining capital, and asset dispositions.

The following tables demonstrate the calculation of Cash Operating Costs, Cash Costs, AISC, and related unit-cost metrics for amounts presented in this press release.

Note: Amounts may not add to totals due to rounding.
