Vista Gold Corp. Files Feasibility Study Update for the Mt Todd Gold Project

Vista Gold Corp. (NYSE American and TSX: VGZ) (“Vista” or the “Company”) today announced that it has filed the feasibility study update for its Mt Todd gold project (“Mt Todd” or the “Project”) located in Northern Territory, Australia in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) disclosure standards on SEDAR+ at www.sedarplus.ca (the “NI 43-101 Report”). As previously reported, a feasibility study update was undertaken in conjunction with the Company’s annual reporting of its mineral resources and mineral reserves disclosed in the technical report summary (the “S-K 1300 Report”) filed with the U.S. Securities and Exchange Commission as an exhibit to the Annual Report on Form 10-K filed on March 14, 2024 (the “Annual Report”), pursuant to Item 1300 of Regulation S-K under the Securities Exchange Act of 1934, as amended (“S-K 1300”).

The NI 43-101 Report reflects changes in project economics since the feasibility study report filed in February 2022. Material capital and operating cost components have been updated with quotes obtained during the first quarter of 2024. The NI 43-101 Report also reflects the current outlook for the long-term gold price and foreign exchange rates, and the recently announced royalty. Mt Todd mineral resources and mineral reserves, mine plans, gold recoveries, and gold production schedules remain unchanged. The technical data and economic conclusions of the NI 43-101 Report are materially identical to the results of the S-K 1300 Report, with differences in the formatting of the reports and details of certain assumptions resulting only from the respective disclosure requirements of NI 43-101 and S-K 1300. Please refer to the Company’s news release dated March 13, 2024.
