Silver King Mining Company, Mineshaft & Main Hoist, Woodside Gulch, Park City, Summit County, UT

Significance: The Silver King Mining Company became one of the major producers in the Park City district of Utah and attained a brief reputation as the richest silver mine in the known world.

One of the smaller but still essential structures at the Silver King Mine was the Main Shaft Hoist House. Built directly over the vertical mine shaft that served as the main outlet for the mine, it was this hoist that lifted the ore the surface. The original hoist was a Corliss engine steam-driven hoist made by Bullock Manufacturing Company and installed in 1893. In 1937, the steam engine was replaced by a 400-horsepower, 2300-volt electric motor, and the old hoist was replaced by a new double reel plate-type friction clutch machine built by Norberg Manufacturing Company.
