This offering consists of a rare 12-acre patented and grandfathered silver–gold mining property located in the historic Calico Mountains mining district of California. The property includes deeded land and mineral rights, proven silver mineralization, and six historic shafts and tunnels extending approximately 60–100 feet deep, reflecting documented underground development. Access is provided via a 4×4 road directly to the site. The mine also features large, untouched historic tailings piles dating to the 1890s, presenting significant potential for modern reprocessing alongside further underground exploration. This is a scarce California mining asset with both near-term surface and longer-term development upside.
