Operation and Mining Development

Operation

Gualcamayo is a gold and silver mine located in Jáchal, San Juan province, Argentina. Aisa Group acquired 100% of the shares of Minas Argentinas SA in September 2023, when the operation was beginning its closure process. After a process of restructuring and capitalization of the company, finances were cleaned up and exploration work was restarted. Aisa Group prioritizes sustainable mining practices, with a strong commitment to the environment and local communities. Our operations are designed to ensure minimal environmental impact while simultaneously promoting the economic and social development of the region.

Potential

Currently, Gualcamayo's production is focused on the secondary recovery of the heap leach. Gualcamayo has certified recoverable reserves of 224 thousand GEO ounces in the heaps. The group is also developing the Deep Carbonates Project, with the aim of completing the technical feasibility by 2025. Exploration work is concentrated on expanding the Deep Carbonates body and developing new targets to generate other sectors with productive potential. Clear evidence has already been found indicating that Gualcamayo hosts primary minerals with economic potential in several of the emerging intrusive bodies.

Highlights

  • Secondary Recovery: The leaching heap has 224 thousand GEO ounces of recoverable reserves. Studies are being conducted with the aim of expanding these reserves to 340 thousand ounces.

  • Resources: The Deep Carbonates Project already has 2.6M GEO ounces of certified Resources, including more than 1.6M ounces in the Reserves category.

  • Exploration: Exploratory efforts are being renewed, and numerous very promising targets have been identified.

  • Certification: The project’s resources are certified in accordance with NI 43-101 standards, ensuring compliance with best international practices.

  • Infrastructure: A fully developed infrastructure supports ongoing and future mining operations.

  • Engineering and Safety: Advanced engineering and mining plans have been implemented, and ongoing metallurgical and environmental studies are yielding positive results. The internal engineering team collaborates with leading international consultants to maintain the highest operational standards.
