Vista’s President and CEO, Frederick H. Earnest, commented, “The FS affirms the strength of Mt Todd’s gold production capacity and ability to deliver solid economic results at a time when inflationary pressures are having significant impacts on operating mines and development projects alike. Completion of the FS represents another major step in de-risking Mt Todd and readying the Project for development. The scale, quality of work completed and location of Mt Todd, together with the completion of the FS and the fact that all major authorizations for development have been obtained, distinguish Mt Todd as a unique development opportunity. We believe the results of the FS will appeal to many potential partners, investors and lenders and allow us to evaluate a broad range of development alternatives as we continue to focus on maximizing shareholder value. (CEO Video)

With Q4 2021 costs, the FS reflects the inflationary pressures being faced currently by all operators in the mining industry. While we believe this inflationary trend is transitory, the resilience of Mt Todd is amply demonstrated by the robust project economics reflected in the FS. Mt Todd’s attributes, together with the deep understanding of the various Project components create valuable optionality in the approach to its development.

Mt Todd’s economic returns benefit from the increase in the gold reserve estimate, favorable results of the power plant trade-off study and slightly lower energy costs in the NT. In view of the current gold price, we increased the gold price used in the reserve estimate from $1,000 to $1,125 and changed the cut-off grade from 0.40 g Au/t to 0.35 g Au/t. These changes, while very conservative, significantly increased the reserve estimate from 5.85 million ounces to 6.98 million ounces. Our power plant trade-off study identified a number of highly-credentialled, well-capitalized power generating companies. Our decision to use a third-party power provider has resulted in important positive impacts to our capital costs and insulates the Project from certain construction and operating risks while maintaining what we believe to be attractive operating costs. While our operating costs have increased as a result of higher labor, reagent, grinding media and over-the-fence power costs, our core energy costs yield some offsetting savings.

In addition to securing the approval of the Mining Management Plan since our last technical report, we have modernized our agreement with the Jawoyn Aboriginal Association Corporation (the “Jawoyn”). We continue to enjoy a close working relationship and their strong support for the Project. The economic returns reflect the increased royalty to the Jawoyn (in lieu of the previous right to a 10% direct Project ownership) as reported in November 2020.”

Mr. Earnest concluded, “Our attention will now focus more intensely on increasing shareholder value and the realization of the intrinsic value of Mt Todd. We believe Mt Todd’s location, scale, economics, permitting status, and extensive technical work represent a unique near-term development opportunity and allow us to evaluate a broad range of development partners, structures and alternatives as we continue to focus on maximizing shareholder value.”

Overview

The technical aspects of the FS are underpinned by extensive metallurgical testing and stringent design criteria that continue to reflect Vista’s rigorous approach to ensuring Mt Todd will meet design and operating specifications. This includes utilizing modern, proven technologies and oversizing processing equipment to best ensure throughput capacity. The FS also incorporates provisions of the recently approved Mt Todd Mine Management Plan, which will subsequently be amended to align with design changes in the FS.

Sensitivity Analysis

The following table provides additional details of the Project’s after-tax economics at variable gold prices and exchange rate assumptions. The Project economics are robust at the FS gold price of $1,600 per ounce and an Fx rate of $0.71 and even more compelling at today’s market conditions. Using a gold price of $1,800 per ounce and an Fx rate of $0.71, the after-tax NPV5% is $1.5 billion and the IRR is 26.7%. For every $100 increase in gold price, the Project NPV5% increases by approximately $230 million.

Capital Costs

Management placed a high priority on controlling capital costs while maintaining the operating cost benefits of a large-scale project. Initial capital costs increased 8% and benefited from savings associated with a favorable trade-off study that supports using a third-party power provider to build, own and operate the power plant at only modestly higher power costs to the Project.

Operating Costs

Operating costs continue to benefit from the economies of scale associated with a 50,000 tonne per day process plant, a low 2.5:1 stripping ratio (unchanged from the last technical report), and a locally-based labor force. Operating costs were impacted by the additional royalty granted to the Jawoyn in exchange for their prior right to a 10% participating interest in the Project.

Mining and Production

The mine plan contemplates that 280.4 million tonnes of ore, containing an estimated 6.98 million ounces of gold at an average grade of 0.77 g Au/t, will be processed over the life of the Project. Total recovered gold is expected to be 6.31 million ounces with average annual gold production expected to be 395,000 ounces. Average annual production over the first seven years of commercial operations is expected to be 479,000 ounces. The Company expects commercial production to commence after two years of construction and six months of commissioning and ramp-up.

The table below highlights the FS production schedule. The shaded portion of the table demonstrates the benefit of sorting that reduces the tonnage processed by 10%, increases the processed grade by a similar percentage, and results in cost savings for grinding, leaching and tailings handling.

As demonstrated in the accompanying chart, the 19% increase in gold reserves sustains a strong production profile over the first seven years with an average of 479,000 ounces of gold per year. The Project also benefits from three additional years of mine life. This reserve growth successfully offsets much of the inflationary pressure on capital and operating costs currently affecting the entire mining sector. The Company believes resource conversion and exploration during the early years of the Project will contribute to improved gold production in years 9 through 11 and further extend the life of the Project.

Project Description

Gold mineralization in the Batman Deposit occurs in sheeted veins within silicified greywackes/shales/siltstones. The Batman deposit strikes north-northeast and dips steeply to the east. Higher grade zones of the deposit plunge to the south. The core zone is approximately 200-250 meters wide and 1.5 kilometers long, with several hanging wall structures providing additional width to the deposit. Mineralization is open at depth as well as along strike, although the intensity of mineralization weakens to the north and south along strike.

The Project is designed to be a conventional, owner-operated, open-pit mining operation that will utilize large-scale mining equipment in a drill/blast/load/haul operation. The Company continues to evaluate the potential use of contract mining and/or autonomous truck haulage. Ore is planned to be processed in a comminution circuit consisting of a gyratory crusher, two cone crushers, two high pressure grinding roll crushers with primary grinding by two ball mills and secondary grinding by 10 FLSmidth VXP mills. Vista plans to recover gold in a conventional carbon-in-pulp recovery circuit.

Opportunities for Adding Value

Additional resources are predominantly at depth and lateral along strike. A portion of the Inferred Mineral Resources are contained within the existing pit design and are currently included in the mine plan as waste material. Potential to convert part of the mineral resources to mineral reserves represents an opportunity to improve existing LOM economics and extend mine life.

The Company also has known mineral resources at the Quigleys Deposit, which is close to the planned processing plant. The estimated grade of the Quigleys Deposit is higher than the estimated average grade of the Batman Deposit and could provide a source of higher-grade feed in the mid years of the Project when the average grade of feed to the plant is expected to decrease. Additional drilling and metallurgical testing are required to develop mine plans and ultimately establish proven and probable mineral reserves at the Quigleys deposit.

Growth through exploration represents additional opportunity to add value at Mt Todd. Both the Batman Deposit and Quigleys Deposit remain open. Recent drilling demonstrates the continuity of mineralization between these two deposits. In addition, Vista controls over 1,500 sq. km of contiguous exploration licenses at the southeast end of the Pine Creek Mining District. Various gold targets have been identified through early-stage, grass roots exploration programs along the Cullen-Australis and Batman-Driffield structural corridors, the latter of which is the host to the Batman Deposit. To-date, Vista’s exploration efforts have primarily focused on the Batman Deposit.

The FS uses a natural gas price comparable to other facilities that self-generate power in the NT. Due to the location of the Project and its close proximity to the main NT natural gas transmission line, the Company believes that there is significant opportunity to achieve a lower natural gas price upon commitment to a long-term gas delivery contract. This belief is in part based on local expectations of significantly increased gas reserves in the Beetaloo Basin south of Mt Todd.

Note Regarding Non-GAAP Financial Measures

In this press release, we have provided information prepared or calculated according to 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 and per tonne processed metrics are not, and are not intended to be, presentations in accordance with U.S. GAAP. These measures 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 will 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 (the Jawoyn Royalty) 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 and per tonne processed basis because we believe these metrics more completely reflect mining costs over specified periods and 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 the Jawoyn royalty. Cash Operating Costs are presented by year in the operating margin summary.

Cash Costs consist of Cash Operating Costs (as described above), plus the Jawoyn royalty. The sum of these costs is divided by the corresponding payable gold ounces or tonnes processed to determine per ounce and 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 payable gold ounces or tonnes processed to determine per ounce and per tonne processed metrics, respectively.

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.
