Overview
The Pan Mine is located approximately 28 km southeast of Eureka, Nevada, along the highly prospective Battle Mountain–Eureka gold trend. It is a Carlin-style gold deposit mined using conventional open-pit methods with gold recovered through heap leaching.
The Pan Gold deposit was discovered in 1978 and has been in continuous production since 2017. Leach pad expansions were completed in 2023 and 2024, adding additional stacking capacity. This enables the seamless processing of future deposits and supports continued mine life extension through exploration.
With numerous targets around the North and South pits remaining underexplored, Minera Alamos sees significant opportunity to ramp up both generative and near-mine exploration to drive future growth.

Technical References
CIM (2014) Definition Standards were followed for Mineral Reserves. Mineral Resources are inclusive of Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Tonnage and grade measurements are in metric units. Contained gold is reported as troy ounces. Mineral resources do not include factors such as mining dilution or mining recovery. There is no certainty that the mine plans and economic models contained in any of the reports will be realized. Numbers may not add due to rounding.
Details of cut-off grades, bulk densities, mining widths, dilution, mining factors, and process recovery assumptions applied to Mineral Reserves and Mineral Resources are provided in the Technical Reports for each mine/project. Unless otherwise stated, Mineral Reserve and Mineral Resource information for each project is summarized, derived, or extracted from the following respective reports:
