A Cu-Ag occurrence/mine located 5 miles S of Owl Head Buttes and N of Marana.

Mineralization has pervasive chlorite alteration and sericite flakes with epidote on fracturing quartz with sulfides. There is a fairly large area of this type (includes TMR-24N) but suspect less than .2% Cu overall on striking major inferred fault, N10 - 20W.

Assay data: Assay report for Arizona Western Mining Company (10-30-70) by the Southwestern Assayers and Chemists, Tucson: 0.23 oz/ton Ag, 0.57% Cu.
