Royal Gold Provides Update on Agreement to Acquire Royalties on the Serrote and Santa Rita Mines

DENVER, COLORADO. SEPTEMBER 29, 2023: ROYAL GOLD, INC. (NASDAQ: RGLD) (together with its subsidiaries, “Royal Gold” or the “Company,” “we” or “our”) announced today that ACG Acquisition Company Ltd. (“ACG”) issued a press release announcing that the transaction for the acquisition by ACG of the entities that own the Serrote and Santa Rita mines in Brazil from funds advised by Appian Capital Advisory LLP (“Appian”) has been terminated. Completion of the now terminated transaction between ACG and Appian was a condition to Royal Gold’s acquisition of royalty interests on the Serrote and Santa Rita mines.

“This transaction was a good opportunity for Royal Gold, but events beyond our control preclude us from completing the acquisition of the royalties,” commented Bill Heissenbuttel, President and CEO of Royal Gold. “While this is an unfortunate outcome, we will continue to look for transactions that meet our strategic criteria for investment.”
