In 1949, Fred Schwartzwalder discovered secondary uranium minerals and radioactive float while investigating an abandoned copper prospect at the site of the present mine. Schwartzwalder obtained a lease from the property owner, Paul White. Very little work was done until 1951, at which time he obtained a Defense Minerals Exploration Administration loan of $30,000 for developing the property. The ore body was classified as a typical hydrothermal ore deposit with primary pitch blende as the principle ore mineral. The ore was purchased by the Atomic Energy Commission at a price fixed by the government and processed by the Vitro Chemical Corporation in Salt Lake City. In 1985 the property was valued at $13,651,000. In 1956 the property was purchased by Denver-Golden Corporation. Shipments of ore to January 1, 1965, totaled approximately 133,000 tons, 1,700 tons produced by Schwartzwalder. 97% of uranium ore mined on the Front Range came from this mine.
