This property was worked as a uranium mine from 1955 to March 1964. Water was kept out until Jan. 1965. Radiation was a problem in this mine until proper ventilation system was installed . A 200-foot ventilator and escape raise to surface was run during 1963 at a location just beyond the underground hoist. The lower three levels were developed through a four-foot by eight-foot two-inch compartment vertical winze (shaft?) some 315 feet in depth. The levels were run out and the vein or deposit and the ore stopped through to the main level. The level average 600 feet running southeast. Prospecting via the core drill method was carried on at great extent and several 1000 feet of core retrieved. The stopes were blocky and after the fill ore was pulled they caved readily. The upper workings are beings used by the Civil Defense Agency for shelter and supplies. 1965 production 805 pounds of uranium valued at 3,620 dollars.
