Sample Mine (Old Sample Mine), Cedar Mountain area, Horse Hills, Antelope District, Tortilla Mts, Pinal Co., Arizona, USA

Latitude: 32°55'19"N
Longitude: 110°50'47"W
A former underground Cu-Ag mine located in sec. 12, T6S, R14E, about 2½ miles E of N from Cedar Mountain (½ mile W of Sample Wash; approximately 6 miles SW of Winkelman), on state land. Produced 1948-1950. Operated by Mr. Roy L. Bishop (1950); and by J. Erklans (1948). NOTE: The MRDS file states that this mine is in the Cottonwood District but more logically should be in the Antelope District.

Mineralization is a vein deposit hosted in Ruin (Oracle) Granite. Local structures include a diabase outcrop along a N-S trend, overall local structure in Precambrian NNW. Vein mineralization is probably associated with a Late Cretaceous-Tertiary intrusive event. Geographically extensive lower Cretateous-Tertiary mineralized system with E-W-trending dikes is found 3 to 5 miles NE of the mine, in the same district, and probably is related mineralization.
