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.

Recent Activity

    November 2022

    During the quarter, a total of 19,856 metres were drilled at the Gualcamayo property in support of resource expansion. At the Deep Carbonate Project, metallurgical testwork to support advancement of the project is underway. The results will help determine whether to move forward with a Preliminary Economic Assessment.

    August 2022

    Mineros S.A. is planning to complete 17,000 m of drilling in proximity to existing mining operations at the Gualcamayo property. The objective is to upgrade mineral resources, provide material for metallurgical test work, resource expansion, and evaluation of the remaining gold in the heap leach pads.
