A former small surface and underground Au placer mining area located in secs. 27, 28 and 35, T19S, R14E in the alluvial cone of the Madera Canyon at the Santa Cruz County - Pima County line, with a radial length of about 5 miles (8.5 km), about 30 miles SSE of Tucson. Worked mostly in the late 1880's.
Mineralization is gold placer deposits in an alluvial cone in the Madera Canyon, heading near White House and the footm of the mountains, at an elevation of about 4,500 feet. The cone slopes northwestward toward Santa Cruz River and has a radial length of at least 5 miles. The placers drain from Santa Cruz County, to the south. It is composed of gravels and sands discharged from the mouth of the canyon. These gravel deposits are 8,046.5 meters wide at most and, in places, are probably over 100 feet (30.48 meters) in thickness and they all carry colors of gold.
Workings include a shaft and many surface workings to 24.38 meters deep. Considerable placer gold was recovered in the late 1880's. Recent activity in 1932-1933, when the deposits were sampled. No production record.
