Probably originally staked in early 1920's
Location: This prospect is in Section 25 at an elevation of about 1350 feet on the divide between Boundary and Daly creeks, and about 0.1 mile from Daly Creek (Elliott and Koch, 1981, p. 16, loc. 64). The location is probably accurate within 0.1 mile.
Geology: The country rocks in the area of this prospect are pelitic metasedimentary and subordinate andesitic (greenstone) metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Triassic Texas Creek Granodiorite, which underlies and locally intrudes the Hazelton; the Eocene Boundary Granodiorite, which intrudes the Hazelton and Texas Creek rocks, and still-younger Tertiary lamprophyre dikes, which cut all the other rocks (Smith, 1973, 1977; Koch, 1996). The deposit (Buddington, 1929, p. 88) consists of greenstone containing calcite veinlets with sphalerite, pyrite, and galena, and small amounts of pyrrhotite, chalcopyrite, and tetrahedrite. Some of the greenstone contains disseminated pyrite and pyrrhotite.
Workings: Deposit was explored by opencuts and a 75-foot adit, probably in the 1920's.
Alteration: Part of the greenstone country rock is impregnated with sulfide minerals.

Commodities (Major) - Cu, Pb, Zn
