Bozeman Corundum Co. Mine


The Bozeman Corundum deposit is located in section 31, T2S, R4E on a flat, northeast trending ridge end about 12 air miles from Bozeman. The deposit was located in 1902 and first worked by the Bozeman Corundum Company. About 1,000 tons of rock was sent to a nearby mill at the Gallatin mine. The Bozeman mine closed after the Gallatin mine closure had left it without a mill. The mine was developed in two groups. The northern deposits were explored by 14 trenches, a shaft and two short adits. The southern deposits, 600 feet (ca. 183 m) southwest, contained 16 trenches, four pits and one adit. In 1944, the U. S. Bureau of Mines reopened three adits and bulldozed about 4,000 feet (1.22 km) of trenches (Heinrich 1948).
