Geologic Map
Gilluly, 1946, Geologic map and sections of the Ajo mining district, Pima County (pi. 20), scale 1:12,000.
Access
From Yuma, 117 miles east on U.S. Interstate 8 to Gila Bend; from there 42 miles south on State Highway 85 to Ajo.
Extent
A small placer deposit is found in gravels in Cornelia Arroyo (sees. 23 and 26, T. 12 S., R. 6 W.).
Production History
24 ounces of gold was recovered during the period 1932-33 at a time when the New Cornelia copper mine was closed; apparently, no placer gold has been recovered since that time.
Source
The gold is evidently derived from the oxidized part of the New Cornelia ore body, which contains about 0.0067 ounce of gold per unit of copper.
