A former Ag-Au-Cu-Pb-Zn mine located in T.21S., R.10E. Owned/operated at times, or in part, by Goon; Lim (1935); Soto; and The Richard M. & M. Co.
Mineralization is numerous, scattered, oxidized and weathered, irregular quartz-fissure veins containing spotty base metal sulfides in a Laramide granitic intrusive. There is near-surface enrichment.
Workings include shallow openings. This group produced some 400 tons of ore averaging about 0.6 oz. Au/T and 7 oz. Ag/T, 0.4% Cu and 0.2% Pb, during the 1930's.
No minerals currently recorded for this locality.

Description: Moderately to strongly consolidated conglomerate and sandstone deposited in basins during and after late Tertiary faulting. Includes lesser amounts of mudstone, siltstone, limestone, and gypsum. These deposits are generally light gray or tan. They commonly form high rounded hills and ridges in modern basins, and locally form prominent bluffs. Deposits of this unit are widely exposed in the dissected basins of southeastern and central Arizona. (2-16 Ma)
Comments: In dissected basins of southeast and central Arizona
