A group of 3 unpatented tungsten claims in Schaffer Canyon, SE portion of the Baboquivari Mountains. Started 1939 and owned by G.T. Harford & C.E. Bent (discoverers).

Mineralization is a faulted complex of siliceous sedimentary beds & volcanic rocks intruded by dikes of acidic & intermediate composition. The vein is 6 to 18 inches (15 to 45 cm) wideand dips 10º to 20º Westward and consists of dull-white quartz with tungsten minerals.
