An Fe-Ti-Cu-Au occurrence located in sec. 14, T15S, R2E at Quijotoa, 3 miles SW of the Quijotoa Trading Post.
Mineralization is a replacement deposit with ore in intermittent bands. The bands were found in a zone of highly epidotized granite, ranging from 100 to 300 feet wide. Individual bands of magnetite and hematite are 4 to 30 feet thick. Extensive magnetite sand placer deposits containing gold are present in the desert floor.
The ore body is 4,827.9 meters long, 91.44 meters wide and 152.4 meters deep. It strikes N30W and dips 75NE. Then host rock is epidotized granite.
