VANCOUVER, July 20, 2020 - Prime Mining Corp. (TSX.V: PRYM) (OTCQB: PRMNF) (Frankfurt: A2PRDW) (“Prime” or the “Company”) is pleased to announce that the Company has completed the acquisition of the Los Reyes gold and silver property in Sinaloa, Mexico (“Los Reyes”) with a payment of US$1,500,000 to Vista Gold Inc.

Prime is required to pay Vista an additional US$2,100,000 through two payments of: (i) US$1,100,000 no later than six months from the Acquisition Date; and (ii) US$1,000,000 no later than twelve months from the Acquisition Date. If the Company fails to make the two payments, Vista’s net smelter royalties and back-in right will be reinstated.
