 The mid-20th century was a turbulent period for the El Dorado mine, as gold mining was halted by order of President Franklin D. Roosevelt during World War II, and individual mining claims were hamstrung by the government's imposition of a fixed price for gold.Small claims became less and less profitable to mine, and operations at the El Dorado mine ground virtually to a halt.The mine was eventually purchased by Andrew Wescott, a Fairbanks gold miner, in the late 20th century.
