A former lode Au-Ag-Cu occurrence/mine located in the NW¼ sec. 13 & in the NE¼ sec. 14, T47N, R15E, MDM, 1.9 km (1.2 miles; 6,300 feet) S of Yellow Mountain (coordinates of record) (¾ mile SE of Little Lily Lake), on National Forest land. MRDS database stated accuracy for this location is 1,000 meters.
Mineralization is a vein deposit (Mineral occurrence model information: Model code: 151; USGS model code: 25d; Deposit model name: Epithermal vein, Sado; Mark3 model number: 28; USGS model may also be 25A: Hot-spring Au-Ag), hosted in Pliocene andesite. The ore body strikes N70W and dips 75S with a length of 426.72 meters. Outcrops well up on the side of the mountain. The wallrock is of fine-grained andesite. It is coarser-grained with depth. There are several veins on these claims. Local rocks include Tertiary volcanic flow rocks, unit 17 (Cascade Range).
Related tectonic structures include the Basin and Range province.
Workings include underground openings with a length of 152.4 meters and comprised of a 2-compartment shaft at least 160 feet deep. An upper adit crosscuts to the vein for 78 feet with a W 30 foot drift on the vein and a lower crosscut adit 42 feet with 190 foot W drift.
