A Au occurrence located in the SW¼ sec. 3, T15S, R23E, SBM, 8.3 km (5.2 miles) ESE of Pebble Mountain (coordinates of record) and 13.7 km (8.5 miles) SSE of Picacho, along the S side of Senator Wash. MRDS database accuracy for this location is not stated.

NOTE: The USGS MRDS database presents MRDS file #10163424 as a related file; however, that file pertains to another locality with a similar name.

The ore body is 0.61 meter wide and 60.96 meters long. The surface is covered with a thin mantle of debris from basalt flow overlying gneiss to the SW. Ridges to the NE are underlain by Tertiary pyroclastics. Au-bearing stringers occur in Precambrian (?) gneiss that extends a known distance of about 1 mile under the mountain. The gold occurs as fine leaf. Local rocks include Tertiary nonmarine rocks, undivided.

Workings include surface and underground openings comprised of shallow shafts, trenches and cuts.
