Vista Gold Corp. Announces Updated Feasibility Study for the Mt Todd Gold Project

In this article:

DENVER, March 13, 2024--(BUSINESS WIRE)--Vista Gold Corp. (NYSE American and TSX: VGZ) ("Vista" or the "Company") announces the results of the feasibility study update for its Mt Todd gold project ("Mt Todd" or the "Project") located in Northern Territory, Australia which was undertaken in conjunction with the Company’s annual reporting of its mineral resources and mineral reserves in its Annual Report on Form 10-K, as required under Item 1300 of Regulation S-K under the Securities and Exchange Act of 1934, as amended ("S-K 1300").

The updated feasibility study reflects changes in project economics since the feasibility study filed in February 2022. Material capital and operating cost components have been updated with quotes obtained in Q1 2024. The updated study also reflects the current outlook for the long-term gold price and foreign exchanges rates, and the recently announced royalty. Mt Todd mineral resources and mineral reserves, mine plans, gold recoveries, and gold production schedules remain unchanged.

Highlights of the Mt Todd 2024 Updated FS appear below, with changes from the 2022 feasibility study shown in parenthesis ( ):

  • After-tax NPV5% of $1.13 billion (+$131.5 million) and IRR of 20.4% (-0.2%) at a $1,800 gold price and a $0.69 Fx rate(1)(2);

  • Average cash costs of $913 (+$96) per ounce (life of mine)(3);

  • Average all-in sustaining cost ("AISC") of $1,034 (+$104) per ounce (life of mine)(3); and

  • Initial capital requirements of $1.03 billion (+$138 million), which continues to reflect the use of a third-party owner/operator of the power plant.

(1)

All dollar amounts stated herein are in U.S. currency and are expressed as $ unless specified otherwise. All foreign exchange ("Fx") rates are in U.S. dollars per Australian dollar.

(2)

The 2022 feasibility study economics were reported at a gold price of US$1,600 and Fx rate of 0.71.

(3)

Cash costs per ounce and AISC per ounce are non-GAAP financial measures. See "Note Regarding Non-GAAP Financial Measures" below for a discussion on non-GAAP financial measures and a reconciliation to U.S. GAAP measures.

Using a gold price of $2,100 and a $0.66 Fx rate, which the Company believes are more reflective of current market conditions, the after-tax NPV5% of the Project is $1.88 billion and the IRR is 29.6%.

Frederick H. Earnest, President and CEO of Vista Gold, commented, "Mt Todd is a robust project with strong leverage to the gold price. Project economics are approximately the same or slightly better than reported two years ago, inclusive of cost increases that have affected the entire gold mining sector. We are pleased that Mt Todd’s value is confirmed at the given foreign exchange rates and conservative gold price selected.

"These results do not change our strategy for Mt Todd. We continue to work with CIBC Capital Markets ("CIBC") to identify and advance interest in Mt Todd and are focused on achieving a transaction that maximizes shareholder value. Our evaluation of a smaller-scale, staged development strategy to advance Mt Todd is ongoing and complements the work that we are doing with CIBC."

Economic analysis conducted only on proven and probable mineral reserves.

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.

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.
