The Stillwater Complex, located near the town of Nye in the Beartooth Mountains of southern Montana, has been mined for various minerals by various companies since the late 1800s. Prospectors first searched the area for gold in 1883 but nickel and copper were the first to be extracted. Chromite was first mined there in 1905; Anaconda Copper developed its Mouat chromite mine in World War II, and also mined for the strategically important mineral during the Korean War.
