A group of Au-Ag-Cu claims located in sec. 33, T2S, R22E, about 5 miles NNE of Bylas at the foot of the southern slope of the Gila Mountains. Discovered July, 1920 by Messrs. James Stevens, William Stevens, Richard Bylas, and John Rope.

Mineralization is weakly metallized vein over a length of 200 feet (60.96 meters) and a width of 1.22 meters along a fault striking N75W and dipping 75NE. This fault brings Cambrian quartzite on the south against Devonian to Carboniferous limestones on the north. At the center area, the fault zone is composed of an approximate 2 feet of greenish to reddish clay gouge and about 2 feet of milky quartz veinlets containing minerals. The vein has sharp contact with clay gouge of the fault, but is irregular in contact with the limestone.

Cambrian quartzites and Devonian & Carboniferous limestones are exposed. These are overlain by Tertiary volcanic flows. In general, Paleozoic rocks strike NW-ward and dip at low angles toward the SW or NE.

Workings include shallow open cuts and pits totaling 60.96 meters in length. Assay grab sample: 0.01 oz Au/ton, 0.4 oz Ag/ton, 2.27% Cu.
