The Gualcamayo mine is an open pit and underground mine and heap leach operation that reached commercial production in 2009. The process facility at Gualcamayo is designed to treat 24,000 tpd and includes a primary, secondary, and tertiary crushing circuit. Gold recovery of approximately 60% is achieved with heap leaching and activated carbon in an ADR plant where gold doré is produced and sent to a refinery.
Mineros announced in June 2021 that the Gualcamayo Mine Mineral Reserves are expected to be depleted by the end of 2022, although a minimal amount of gold will continue to be recovered from stockpile material in 2023 and 2024 through heap leach processing.
