A copper-molybdenum mine east of Chewelah above Thomason Creek. The geology is veins along the contact between metamorphosed Upper Paleozoic dolomite and the Flowery Creek Granodiorite. Development consisted of a 292' deep shaft with 850' of workings along it, along with some short adits and shafts. It produced three carloads of ore in 1917 and an additional 300 tons around 1940.

Alteration: Calc-Silicates In Marble.

Deposit: The main vein characterized in places by a single gouge band a few inches thick and elsewhere by a zone of brecciation 4 to 6 ft wide. Ore bodies lenticular in plan and are As much As 130 ft long and 4 ft wide.

Rock formation(s): Flowery Trail Granodiorite, Monzonite
Fine Grained White To Green Marble
