A Au-Ag mine located in the NE¼SW¼ sec. 22, T22N, R20E, on the west side of Squilchuck Creek.

It worked mineralization disseminated and in stockworks in pervasively altered and silicified sandstone of the Eocene Chumstick formation and an underlying unnamed sandstone unit.

Developments include 2 open stopes, 5 adits, 7 main levels and 6 sub-levels totaling about 12 miles of workings.

It produced 280 tons of ore in 1894, 170 tons in 1910, 20,000 tons in 1938-39, 6,216 tons in 1944-1946, and continual production from 1949 to 1967. Production records from 1954 to 1967 show 410,000 ounces of Au, 600,000 ounces of Ag from approximately 1,000,000 tons processed. Currently (2008) being re-opened by The Lovitt Mining Company, a subsidiary of Lovitt Resources (ticker: LRC-V).

Total remaining indicated reserves are 435,000 ounces of Au and 750,000 ounces of Ag.

Production scheduled to be underway Spring 2009.

Note: a visit by Norman King on October 24, 2014 showed no signs of recent activity.

ID: 1435231
Nahahum Canyon Member, Chumstick Formation

Age: Eocene (33.9 - 56 Ma)

Lithology: Continental sedimentary deposits or rocks

Eocene - Late Cretaceous
33.9 - 100.5 Ma

ID: 2769793
Paleocene-Cretaceous nonmarine rocks

Age: Phanerozoic (33.9 - 100.5 Ma)

Stratigraphic Name: Chuckanut Formation; Guye Formation; Pipestone Canyon Formation; Swauk Formation; Chumstick Formation

Description: Brown-gray to light-gray, medium- to course-grained massive cross-bedded arkose with interbedded conglomerate and siltstone. Contains several coal seams in Whatcom County. Iron-rich laterite at base near Cle Elum and Blewett Pass in Kittitas and Chelan Counties.

Comments: Two polygons on the digital coverage are tagged as TKc (the original name of this unit). Chumstick formation is usually referred to as Swauk formation but is younger in age (middle Eocene as opposed to early Eocene) (Tabor and others, 1987).
