​ Vista acquired Mt Todd in March 2006. The transaction-related costs of $2,146 were capitalized as mineral properties. This amount included the purchase price, costs associated with related commitments, and transaction costs. Since 2006, the Company has systematically advanced the project through exploration, metallurgical testing, engineering, and site management activities. Costs associated with these activities were charged to expense as incurred. See Note 8 for other commitments to the Jawoyn Association Aboriginal Corporation (the “JAAC”). ​ Guadalupe de Los Reyes, Sinaloa, Mexico ​ As of June 30, 2020, the Company held the Guadalupe de los Reyes gold and silver project in Sinaloa, Mexico (“Los Reyes”), which was subject to an agreement with Prime Mining Corporation (“Prime Mining”). In June 2020, the Company amended the agreement to accelerate Prime Mining’s final $1,500 payment required to complete the purchase of Los Reyes and to require additional payments of $2,100 by Prime Mining in lieu of Vista being granted certain royalty and back-in rights, with $1,100 due in January 2021 and $1,000 due in July 2021. The previous $4,500 paid to date was applied first to reduce our carrying value to zero, with the remaining $2,892 recorded as a deferred option gain. The Company received the final $1,500 purchase price payment in July 2020 and transferred control of the Los Reyes project to Prime Mining. With transfer of control, Vista will recognize the $2,892 deferred option gain as income during the three months ending September 30, 2020. ​ Awak Mas, Sulawesi, Indonesia ​ Vista holds a net smelter return royalty (“NSR”) on the Awak Mas project in Indonesia. 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. 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 holder of Awak Mas or a nominated party now has the right to cancel the remaining 1% NSR and 1.25% NSR for an additional payment of $2,500 by April 30, 2021, at which time the Company will recognize a gain for this amount and $68 that is currently carried as deferred option gain. If the holder does not make this final payment by April 30, 2021, Vista will retain the remaining royalty interests.
