A former surface and underground Mn mine located in sec. 17, T.11N., R.3W., on the Agua Fria River, 12 miles SE of Mayer, near Sycamore Creek above its junction with the Agua Fria River. This is on the opposite side of the river from the Bunker & Rogers claims. Discovered 1952. Claims extend into sec. 20.
Mineralization is ore in nodules in horizontal lenses, associated with travertine.
The deposits lie in a bench that rises 75 feet (23 meters) above the river, whose altitude at this point is 3,500 feet. Dominant rocks of the region are schists and intrusive igneous rocks, but the low-lying country through which the Agua Fria River flows is largely covered with basalt. The deposits occur as nodules in sand associated with magnesian travertine in which there are bands & nodules of a waxy, white & yellow chert. The travertine is reported to merge horizontally into a volcanic agglomerate with calcareous cement, which is overlain by basalt. The nodules and small masses of manganese ore come from depths of not more than 6 feet (2 meters). The psilomelane ore generally lies in horizontal lenses, the largest of which was reported to be 2 feet thick.
Workings include a number of shallow holes (1917). 30 tons of ore at 44.56% Mn were produced that year
