Etta, Etta Camp, Etta Mine, Pennington county, South Dakota

The Etta mine began operations in 1883. At that time, the mine was owned by the Harney Peak Tin Mining, Milling, and Manufacturing Company which built a mill and smelter at the mine. In 1898, the mine started shipments of spodumene, a lithium ore, and it operated until 1959. It became famous for the huge spodumene crystals it produced. The old Etta tin smelter still stands three stories high, half-a-mile south of Keystone. The Etta mine, with its gaping hole, is a spectacular sight

Mine remains, it is on private property and visitors are not welcome.
