Basin Gulch lies within the historic Philipsburg Mining District, which Lannister Mining describes as the district that led the original US silver boom in the late 1800s. The University of Montana records that one Philipsburg-area mine produced $20 million in silver between 1885 and 1893.
Montana itself is known as the Treasure State. Its first gold discovery came in 1852 at Gold Creek, near present-day Garrison, and silver, copper, nickel and platinum have all been mined here since.
