The Golden Chest: Underground Operations at Idaho's Largest Producing Gold Mine

Modern mining operations started at the Golden Chest with New Jersey Mining Company in the early 2000s. Since then, more that $14M has been invested in infrastructure, exploration, and development. Underground operations account for approximately 2,000 troy ounces of gold production per year with increased production on the horizon. The Idaho Vein is currently being mined in the Skookum Shoot by underhand cut and fill methods using cemented rockfill for support.
