A lead-zinc-silver prospect by Great Western Lake ~5 miles NW of Nespelem. It worked a small body of sedimentary rock surrounded by metamorphosed granite. Development consisted of multiple shafts, one being 40' deep with some levels.
Deposit: Small body of sedimentary rock surrounded and metamorphosed by granite. 3 claims.
Development: Shafts with levels; baby hoist.
Geology: Considerable glacial drift is strewn over the surface. Outcrops range from a rusty qtz-mica schist containing veinlets of aplite, pegmatite, and qtz to a banded hornstone, portions of which have disintigrated to gossan-like masses of limonite showing the stain of Mn oxides. The sulfides and magnetite are intergrown with the silicates and appear to have been introduced when the rocks were metamorphosed. ; geol.desc: sed. Rocks surrounded, metamorphosed by granite
Rock formation(s): Colville Batholith
Covada Group
Ore(s): Contact Zone Between Granite And Sed Rocks
