At its peak in 1941, the company operating Independence Mine employed 204 men, blasted almost 12 miles of tunnels, and produced 34,416 ounces of gold worth $ 1,204,560; today $ 17,208,000.  World War Two rendered gold mining nonessential, although Independence Mine continued to operate due to the presence of sheelite (a source of tungsten, which is a strategic metal).  But supplies were low and the mine closed in 1943.
