Nature of Operations and Basis of Presentation	VISTA GOLD CORP. NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Dollar amounts in U.S. dollars and in thousands, except share-related amounts) 1. Nature of Operations and Basis of Presentation Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) operate in the gold mining industry. We focus on evaluation, acquisition, exploration and advancement of gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements with other mining companies, or outright sales of assets for cash and/or other consideration. We look for opportunities to improve the value of our gold projects through exploration drilling and/or technical studies focused on demonstrating the economic and technical feasibility of our projects. We do not currently generate cash flows from mining operations. The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) in Northern Territory, Australia. Vista held other non-core assets at September 30, 2021, including royalty interests in the United States and Indonesia, mill equipment not in use and listed for sale, and listed equity securities. The interim Condensed Consolidated Financial Statements (“interim statements”) of the Company are unaudited. In the opinion of management, all adjustments and disclosures necessary for a fair presentation of these interim statements have been included.

Short-term and Other Investments	3. Short-term and Other Investments Short-term investments As of September 30, 2021 and December 31, 2020, the amortized cost basis of our short-term investments was $nil and $400, respectively, which approximated fair value. Short-term investments at December 31, 2020 were comprised of U.S. government treasury securities, which had maturity dates on the date of purchase greater than 90 days but less than one year. Investments with maturity dates of 90 days or less were included in cash and cash equivalents. Other investments The Company’s investment in 1,333,334 common shares of Nusantara Resources Limited (“Nusantara” and “Nusantara Shares”) was recorded at fair value in the Unaudited Condensed Consolidated Balance Sheet at September 30, 2021 and December 31, 2020. Vista also held common shares of Midas Gold Corp. (“Midas Gold Shares”) during a portion of 2020; all Midas Gold Shares were sold prior to 2021. The fair value of other investments was $334 and $293 at September 30, 2021 and December 31, 2020, respectively. Changes in fair value of the Nusantara Shares and Midas Gold Shares, representing unrealized gains (losses), were recorded in the Unaudited Condensed Consolidated Statements of Income/(Loss) in the period in which the changes occurred. No listed securities in other investments were sold during the three and nine months ended September 30, 2021. During the three months ended September 30, 2020, the Company sold its remaining 4,667,615 Midas Gold Shares for net proceeds of $4,835, at a gain of $2,454 based on the most recent measurement period of June 30, 2020. During the nine months ended September 30, 2020, the Company sold 6,882,115 Midas Gold Shares for net proceeds of $5,788, at a gain of $2,574 based on the most recent measurement periods of June 30, 2020, March 31, 2020 and December 31, 2019. On September 22, 2021, the shareholders of Nusantara approved a scheme of arrangement whereby PT Indika Mineral Investindo offered to acquire all issued shares of Nusantara for A$0.35 per share. The transaction closed on October 6, 2021, resulting in Vista receiving $339 upon tendering its Nusantara Shares.

Mineral Properties Mt Todd, Northern Territory, Australia The capitalized mineral property values are as follows: At September 30, 2021 At December 31, 2020 Mt Todd, Australia $ 2,146 $ 2,146 Vista acquired Mt Todd in March 2006. Transaction-related costs of $2,146 were capitalized as mineral properties. This amount included the purchase price and related transaction costs. Since 2006, the Company has systematically advanced the Project through exploration, metallurgical testing, engineering, and environmental/operational permitting activities conducted in addition to ongoing site management activities. Costs associated with these activities were charged to expense as incurred. See Note 8 for commitments to the Jawoyn Association Aboriginal Corporation (the “Jawoyn Association”). Guadalupe de Los Reyes, Sinaloa, Mexico In July 2020, the Company completed the sale of the Guadalupe de los Reyes gold and silver project (“Los Reyes”) to Prime Mining Corporation (“Prime Mining”). Under the terms of sale, Prime Mining was required to make additional payments to Vista of $2,100 in lieu of Vista being granted certain royalty and back-in rights. Prime Mining paid $1,100 in January 2021 and $1,000 in June 2021. Having received these payments as scheduled, Vista has no remaining right to be granted the royalties and back-in right, and Vista recognized a gain on disposal of mineral property interests of $2,100 during the three months ended June 30, 2021. Awak Mas, Sulawesi, Indonesia Vista holds a net smelter return royalty (“NSR”) on the Awak Mas project. During 2019, Vista and the holder of Awak Mas amended the original royalty agreement to allow the holder or a nominated party to make a $2,400 payment to Vista by April 30, 2020 to cancel a 1% NSR on the first 1,250,000 ounces produced at Awak Mas and a 1.25% NSR on the next 1,250,000 ounces produced. The holder of Awak Mas is a subsidiary of Nusantara. On May 5, 2020, the Company received $2,400 to cancel the related 1% NSR and 1.25% NSR. The gain recognized upon receipt of this payment was $2,568, which included the $2,400 payment plus $168 of previously deferred option gain. The Nusantara subsidiary or a nominated party also had the right to cancel the remaining 1% NSR and 1.25% NSR for an additional payment of $2,500 by April 30, 2021. Vista and the Nusantara subsidiary agreed in April 2021 to extend the payment date for the remaining $2,500 to not later than January 31, 2022 upon payment of certain extension fees. Vista received $315 during the nine months ended September 30, 2021 for extension fees. The gain associated with these fees was deferred until the final royalty payment is received or the extension expires and will be recognized as income at that time. If the holder does not make the final $2,500 payment by not later than January 31, 2022, Vista will retain the remaining royalty interests. See Note 3 regarding the Company’s tender of its Nusantara Shares in connection with the sale of Nusantara. This transaction had no effect on the terms of the agreement between Vista and the Nusantara subsidiary.

Each Unit consisted of one common share in the capital of the Company (each a “Common Share’) and one-half of one Vista is a party to an at-the-market offering agreement (the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”), under which the Company may, but is not obligated to, issue and sell Common Shares through Wainwright for aggregate sales proceeds of up to $10,000 (the “ATM Program”). No securities will be offered in Canada under the ATM Agreement. The ATM Agreement was amended in June 2020 to remain in force until terminated by either party. During the three and nine months ended September 30, 2021 the Company sold nil and 798,270 Common Shares, respectively, under the ATM Program for net proceeds of $nil and $871, respectively.

Each sale under the ATM Agreement was made pursuant to an “at the market offering” as defined in Rule 415 under the United States Securities Act of 1933, as amended. In July 2021, the ATM Program was suspended in conjunction with the public offering of shares. Vista could use the ATM Program in the future following filing and effectiveness of a new shelf registration statement with the Securities and Exchange Commission.

Commitments And Contingencies
Commitments And Contingencies	8. Commitments and Contingencies Our exploration and development activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. As such, future expenditures that may be required for compliance with these laws and regulations cannot be predicted. We conduct our operations in a manner designed to minimize effects on the environment and believe our operations are in compliance with applicable laws and regulations in all material respects. In November 2020, we modified our agreement with the Jawoyn Association with respect to Mt Todd. The modified agreement provides the Jawoyn Association with a gross proceeds royalty (“GPR”) ranging between 0.125% and 2.0%, depending on prevailing gold prices and foreign exchange rates, instead of its previous right to become a 10% participating joint venture partner in the Mt Todd project. The modified agreement did not affect the previously agreed 1.0% GPR granted to the Jawoyn Association. The combined GPR now ranges from 1.125% to 3.0%.
