DENVER, Oct. 7, 2019 /PRNewswire/ -- Vista Gold Corp. ("Vista" or the "Company") (NYSE American and TSX: VGZ) today announced that it has completed and filed the National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") preliminary feasibility study (the "PFS") for its Mt Todd gold project ("Mt Todd" or the "Project") in Northern Territory, Australia to support the results of its updated preliminary feasibility study announced on September 10, 2019. The PFS successfully confirmed the efficiency of ore sorting across a broad range of head grades, the natural concentration of gold in the screen undersize material prior to sorting, the efficiency of fine grinding and the resulting improved gold recoveries, and the selection of FLSmidth's VXP mill as the preferred fine grinding mill.

The PFS provides an assessment of the Project at a gold price of US$1,350 per troy ounce with a foreign exchange rate of US$0.70 per Australian dollar. The base case for the PFS evaluates a 50,000 tonne per day ("tpd") owner-operated, open-pit operation with a conventional three-stage crush and two-stage grind comminution circuit followed by a carbon-in-pulp gold recovery circuit. The results of an alternate case designed to mine and process 33,000 tpd are also included in the PFS. Additionally, the PFS incorporates the results of metallurgical optimization work, a redesign of the fine grinding circuit, construction and ramp-up schedule changes and a comprehensive review of all aspects of the Project, including consideration of an independent benchmarking study of key PFS parameters. For further information on the results of the PFS and the Project, see the technical report entitled "NI 43-101 Technical Report Mt Todd Gold Project 50,000 tpd Preliminary Feasibility Study Northern Territory, Australia," dated October 7, 2019, with an effective date of September 10, 2019, which is available on SEDAR at www.sedar.com, EDGAR at www.sec.gov, as well as on Vista's website under "Mt Todd – Technical Reports."

Vista's President and CEO, Frederick H. Earnest, commented, "We are pleased with the results of the PFS, which reflect improved average life of mine gold recoveries to 91.9%, net present value at a 5% discount rate ("NPV5%") of $823 million and an internal rate of return ("IRR") of 23.4%, all at a conservative gold price and foreign exchange rate. We believe that Mt Todd has been de-risked through intensive, multi-year studies and application of proven technologies. All major environmental approvals have been received. We believe that Mt Todd is an exceptional asset with a NPV5% of US$1.15 billion and an IRR of 30.2% at the current gold price and foreign exchange rate. We do not believe that the debt and dilution to build Mt Todd on a stand-alone basis is in the best interest of our shareholders. Looking ahead, we are focused on identifying prospective development partners that we believe will recognize the value of Mt Todd, allowing us to provide what we view as appropriate reward for Vista shareholders. We are focused on creating shareholder value, and if needed we are prepared to preserve the value of Mt Todd until an appropriate strategic transaction can be completed that will reward our shareholders."

John Rozelle, Vista's Sr. Vice President, a Qualified Person as defined by NI 43-101, has approved the information in this press release.

Cautionary Note to United States Investors

The United States Securities and Exchange Commission ("SEC") limits disclosure for U.S. reporting purposes to mineral deposits that a company can economically and legally extract or produce. This press release uses the terms "Proven reserves" and "Probable reserves". Reserve estimates contained in this press release are made pursuant to NI 43-101 standards in Canada and do not represent reserves under the standards of the SEC's Industry Guide 7 and may not constitute reserves under the SEC's newly adopted disclosure rules to modernize mineral property disclosure requirements, which became effective February 25, 2019 and will be applicable to the Company in its annual report for the fiscal year ending December 31, 2021. Under the currently applicable SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and all necessary permits and government approvals must be filed with the appropriate governmental authority. Additionally, this press release uses the terms "Measured resources", "Indicated resources", and "Measured & Indicated resources". We advise U.S. investors that while these terms are Canadian mining terms as defined in accordance with NI 43-101, such terms are not recognized under SEC Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the SEC. Mineral resources described in this press release have a great amount of uncertainty as to their economic and legal feasibility. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant "reserves" as in-place tonnage and grade, without reference to unit measures. The term "contained gold ounces" used in this press release is not permitted under the rules of the SEC. "Inferred resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that any or all part of an Inferred resource will ever be upgraded to a higher category. U.S. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into SEC Industry Guide 7 reserves.
