Coast Copper Corp. announced that it has earned a 100% interest in certain mineral claims ("Greater Empire Claims") which form part of the Empire Mine property ("Empire Mine" or the "Property") by making the fifth and final payment, consisting of a cash payment of $250,000 and the issuance of 1,000,000 common shares of Coast Copper to Mirva Properties Ltd. ("Mirva") pursuant to an option agreement that was signed on September 22, 2020 ("Empire Option Agreement"). Empire Mine also consists of certain crown grants ("Quatsino Crown Grants").

To earn its 100% interest in the Greater Empire Claims, Coast Copper made aggregate cash payments of $1,250,000, issued 3,000,000 common shares of the Company to Mirva and completed work commitments on the Property totaling $2,000,000 over a four (4) year period. Mirva retains a 2% net smelter return ("NSR") royalty on the Property of which 1% may be purchased for $1,000,000 at any time up to 120 days after commencement of commercial production. The Empire Option Agreement was structured such that this NSR royalty plus all other NSR royalties which may currently be payable on the Property may not exceed in aggregate 2.5% before buydowns.

To earn a 100% interest in the Quatsino Crown Grants, Coast Copper must pay Mirva the equivalent of $500,000 with either a cash payment or equivalent value in common shares of the Company, at the Company's election, on or before September 22, 2025. The Company has the option to extend the Quatsino Crown Grants payment by one year for a payment of $535,000, two years for a payment of $590,000 and three years for a payment of $665,000.
