A group of 2 Cu-Ag-Au-Mo prospects with underground workings located in the SE¼ sec. 23, T23S, R16E, 2/3 mile south of the Sunnyside Mine and 1½ miles west of American Peak in the extreme head of Alum Gulch, 3 miles SW of Harshaw, on National Forest land. The property comprises the Thunder group of 8 claims and, adjacent to the N, the Standard group of 14 claims.
The deposits are similar to those of the Sunnyside Mine. They occur in shear or sheeting zones in the granite porphyry country rock and contain principally copper minerals. Alteration is silicification. Volcanic rocks are highly altered to quartz, alunite and kaolinite. The associated rock units are the Mt. Wrightson formation, rhyolite and latite flows and tuffs and tuffaceous sandstone. The ore zone depth to top is 6.1 meters. Local structures include NW shear zones and an ENE system of faults and joints with a flat southerly dip. A local tectonic feature is the Thunder Mine block.
Workings include an 82 foot (24.99 meters) tunnel on the Thunder group of claims and a 40 foot shaft on the Standard group of claims. No records of production. The ore was reported to average 0.6% Cu, 2 oz/t Ag, and 40 oz/t Au (1915).
