A Ag,Au,Pb,Mn,Zn,Cu mine
This mine is located on the northeast slope of the Southeast spur of Mineral Hill, 2 miles Southwest of Nespelem
The oxidization zone was no more than 20' deep
It worked tabular lenses and veinlets of ore along an 8'-10' fracture zone in granite.
Developments include a 700' main haulage adit, and 2,500' of workings on 3 levels that include 3 shafts and 3 adits
It produced and shipped 29 tons of ore in 1911-1912. Also in 1916-1917, 1919-1922, 1925-1926, 1937-1940.
The ore was shipped to the Tacoma Smelter (http://www.mindat.org/loc.php?loc=52739)
12 valid minerals.

|Mesozoic granitic rocks, undivided|
Description: Granite, quartz monzonite, quartz diorite, granodiorite, and trondhjemite. Includes diorite in southeastern Washington; diorite and gabbro near Concunully in Okanogan County; gneiss, schist, and migmatites in areas of Chelan, Colville, and Okanogan batholiths. Includes high-grade metamorphic rocks of Precambrian age in Spokane area.
Comments: Colville batholith; Kaniksu Batholith (including Spirit pluton); Loon Lake granite; Mount Stuart granodiorite; Osoyoos granodiorite; Similkameen batholith; Whisky Mountain granodiorite; Cooper Mtn Batholith; Okanogan Batholith; Includes significant portions, primarily orthogneiss, of the Kettle Metamorphic Core Complex and the Okanogan Metamorphic Core Complex, as well as orthogneiss in the Okanogan Batholith area. Metamorphic rocks near Spokane include quartzite and possibly meta-argillite and hornfels of Belt Supergroup (Stoffel and others, 1991). Note that Stoffel and others, 1991, report that while the term "Loon Lake Granite" was once widely used, it has since been abandoned.
