Bald Mountain Mine

—Lead, South Dakota —

The Bald Mountain district, which includes the Portland area, is 3½ miles southwest of the Lead district. Claims were located in the Portland area in 1877, but early mining was handicapped by the highly refractory (difficulty) nature of the ore. About $3 million worth of bullion, mostly in gold, was produced by the Mogul Mining Co. up to 1900. Other companies were also active during this early period.
By 1891, the milling and metallurgical difficulties were overcome by the chlorination process, and in 1892 cyanidation proved even more successful. The Bald Mountain District entered a period of prosperous development that ended at the close of World War I owing to high costs. The increased price of gold in 1934 caused a pronounced reactivation which lasted until World War II. After the war, mining was resumed on a small scale, but increased operating costs again forced the owners to close in 1959. Total gold production of the Bald Mountain District, through 1959, was roughly 1,400,000 ounces.
