Vancouver, British Columbia – Capstone Mining Corp. (“Capstone” or the “Company”) (TSX: CS) and Pembridge Resources plc (“Pembridge”) have elected to terminate the agreement for the sale of the Minto Mine (“Minto”) (the “Transaction”). Due to unfavourable equity market conditions, Pembridge has been unsuccessful in
completing the financing required to complete the Transaction. Additionally, to preserve Minto’s value, Capstone is putting Minto on temporary care and maintenance, while continuing to explore value maximizing alternatives,
including discussions with Pembridge and other potentially interested parties.
