Montana boasts a rich and diverse mining history often encapsulated by its moniker, the Treasure State, with modern operations extracting a variety of valuable industrial and precious minerals. Historically world-famous for its massive copper production centered around the mines of Butte, the state currently produces significant quantities of platinum group metals, palladium, and gold from major operations like the Stillwater Complex. Additionally, active industrial mining yields crushed stone, construction aggregates, lime, talc, and various precious gemstones such as Montana sapphires.
