Definition: the Philipsburg Mining District
The Philipsburg Mining District is a historic mining area in west-central Montana. It led the original US silver boom in the late 1800s. Lannister Miningcites the district's history as part of why it considers Basin Gulch to be in a safe jurisdiction.
Montana is known as the Treasure State for its mineral wealth, and mining still plays an active role in the state's economy today.
