Vista Gold Corp. Announces Third Quarter Financial Results and Mt Todd Update

DENVER, Oct. 23, 2019 -  Vista Gold Corp. (NYSE American and TSX: VGZ) ("Vista" or the "Company") today announced its unaudited financial results for the quarter ended September 30, 2019. Management's quarterly conference call to discuss these results is scheduled for 4:30 p.m. EDT on October 24, 2019. The Company's unaudited condensed consolidated financial statements and management's discussion and analysis, together with other applicable disclosures can be found in the Company's Quarterly Report on Form 10-Q, filed on October 23, 2019 with the U.S. Securities and Exchange Commission and the Canadian securities regulatory authorities. 

Third Quarter Highlights and Recent Developments

• Positive results of the updated October 2019 preliminary feasibility study (the "2019 PFS") for the Mt Todd gold project ("Mt Todd" or the "Project") with improved after-tax net present value at a 5% discount rate ("NPV_5%") of $823 million and internal rate of return ("IRR") of 23.4% at a price of $1,350 per ounce of gold and a $0.70=A$1.00 exchange rate;
• 2019 PFS after-tax NPV_5% of $1.15 billion and IRR of 30.3% at a price of $1,500 per ounce of gold and a $0.68=A$1.00 exchange rate;
• Metallurgical optimization program demonstrated life-of-mine gold recovery of 91.9% and total recovered gold of 5.3 million ounces; and
• Received the third $1.5 million option payment from Prime Mining Corp. for the Company's Guadalupe de los Reyes gold / silver project in Sinaloa, Mexico ("Los Reyes").

Vista's President and CEO, Mr. Frederick H. Earnest commented, "Completing the 2019 PFS was a significant achievement in further advancing and de-risking Mt Todd. With average life-of-mine gold recoveries of 91.9%, NPV_5% of $823 million, an IRR of 23.4% at a $1,350 per ounce gold price and a $0.70=A$1.00 exchange rate, and all major environmental approvals in place, we believe Mt Todd is a superior asset located in a Tier-1 mining jurisdiction. In addition, we believe the independent benchmarking study provides greater confidence to the capital and operating cost estimates in the technical report. These studies provide a solid foundation to further advance the Project and demonstrate that Mt Todd is poised to become a major Australian gold producer. We intend to continue to de-risk Mt Todd in a cost-effective manner while seeking to secure a development partner. The 2019 PFS provides a solid basis for engagement with prospective development partners that recognize the value of Mt Todd.

"We continue to effectively manage our working capital to best improve the value of Mt Todd. We believe our working capital will be sufficient to fully fund our currently planned corporate and project holding costs and discretionary programs for more than 12 months. Vista has other potential future sources of non-dilutive financing that may be converted to additional working capital. These sources include the sale of non-core assets such as our used mill equipment, future option payments for Los Reyes, and monetization of royalty interests held by the Company. We plan to increase our focus on monetizing these other sources of working capital."

Summary of Q3 2019 Financial Results

Vista reported a net loss of $2.5 million, or $0.02 per share, for the three-month period ended September 30, 2019. The loss is comprised of $2.3 million of operating expenses and a $0.2 million mark-to-market loss on our investment in Midas Gold Corp. Operating expenses for the quarter include costs related to the 2019 PFS.

Working capital at September 30, 2019 was $7.2 million, including cash and short-term investments of $4.5 million. The Company has no debt.

Mt Todd Update

2019 PFS

In September 2019, we announced the results of the 2019 PFS for the Project and in October 2019 we filed a technical report entitled "NI 43-101 Technical Report Mt Todd Gold Project 50,000 tpd Preliminary Feasibility Study Northern Territory, Australia" with an effective date of September 10, 2019 and an issue date of October 7, 2019.  The 2019 PFS was based on the results of metallurgical testing, a comprehensive review of the Project and the re-design of elements of the process flow sheet, and most importantly, grinding circuit design changes. Key inputs that changed in the 2019 PFS include higher gold recoveries due to the finer grind size, a higher gold price, and improved foreign exchange rates.

These process improvement efforts resulted in revised estimates that reflect reduced estimated operating costs, increased projected gold recovery and higher gold production forecasts. In addition, we updated revenue, capital, and operating costs based on current market conditions and recent quotes from suppliers.

Vista retained GR Engineering Services of Perth, Australia to undertake an independent benchmarking study to assess the appropriateness of capital and operating cost estimates, construction and ramp-up schedules, owner's costs and key components of the Project, such as power supply.

Metallurgical Optimization Program

Vista's latest metallurgical test programs have confirmed: (1) the efficiency of ore sorting across a broad range of head grades and the natural concentration of gold in the screen undersize material prior to sorting; (2) the effectiveness of fine grinding and improved gold leach recoveries at an 80% passing grind size of 40 microns ("µm"); and (3) the selection of FLSmidth's VXP mill as the preferred fine-grinding mill.

Vista initiated a metallurgical optimization program (the "Program") following the issuance of its 2018 preliminary feasibility study ("2018 PFS"). The objective of the Program was to determine overall gold recoveries at finer grind sizes and evaluate the efficiency of the FLSmidth VXP mills as opposed to the Glencore ISA mills, which were contemplated in the 2018 PFS. As a result of this test work and related leach recovery tests, a final grind size of 80% passing 40µm was selected. The Program was completed during the third quarter of this year. The outcomes of the metallurgical testing and other findings were incorporated into the 2019 PFS.

In August 2019, the Company announced the results of the 2019 fine-grinding tests completed on samples of various grade ranges. These tests confirm that the Mt Todd ore can be efficiently ground to a finer final product size with lower power consumption in the grinding circuit than estimated in the 2018 PFS. Leaching the 40µm size material resulted in higher life-of-mine recoveries of 91.9% compared to 86.4% in the 2018 PFS, and an estimated increase in total gold produced over the life of the mine of approximately 349,000 ounces. It also proved that at the 40µm target grind size, the tail grade is nearly constant within specific grade ranges. 

Project Mineral Reserves

The 2019 PFS estimated total recovered gold at 5.3 million ounces. The table below presents the estimated mineral reserves for the Project.
