Access Description: Proceed west on Hwy 11-17 to Hwy 588. Turn left onto Hwy 588, and proceed 10.5 km to a small winter road on the left side of the highway approx. 200 m past Silver Creek. Proceed down the road 445 m to an overgrown path on the right. Follow the past for 50 m to the mine workings.
1886: T.A. Keefer discovered the vein. 1909: An adit was driven by F. Keefer along the No. 2 vein for 76.2 m and a shaft kinking up to the adit at 24 m was sunk to a depth of 31.7 m. 1910: mine operated for a short time. 1914: the shaft was sunk an additional 8.8 m to a depth of 40.5 m. At the 15 m level, drifts were cut 1.5 m NE and 30.5 m SW. In the SW drift, a 4.5 m raise was cut 10.7 m from the shaft. 1931: Animikie Mines optioned the property. 1965: Climax Silver Mines leased the property to G.C. Silverman, who dewatered the shaft, and chip sampled the drift. 1968-69: G.C. Silverman conducted geological mapping and sampling. 1993: J. Redden conducted prospecting and stripping.

Jan 29, 2018 (Therese Pettigrew) - The Porcupine, Badger, Climax, and West Beaver mines adjoin one another and their workings are on a closely related system of veins that appear in notches around the sides of a small diabase-capped upland, lying about 1.2 km NW of Rabbit Mountain. The No. 2 vein associated with the West Beaver Mine is exposed a few feet above and below the collar of the shaft in the diabase. The vein occupies a shatter zone 0.3-0.6 m wide, trending 40 degrees, and dipping vertically. The mineral assemblages that form in the vein system consist of fine-trained white quartz, white and buff calcite, green fluorite, sphalerite, galena, a little chalcopyrite and occasional small blebs of argentite. The final state of mineral development in the vein system involved the growth of coarse crystalline quartz into vugs. The tips of the quartz crystals are amethystine and occasionally later deposits of pyrite, black sphalerite, calcite, and purple fluorite are found on them. Leaf argentite is associated with the lasted formed minerals and occupies joints and cleavage planes in various parts of the vein system (Tanton, 1931). The vein averages about 1’ in width. In 1910, there were a few tons of good ore in the ore-house, said to have come from the shaft (Corkill, 1911). Creswel reported assays up to 92.0 opt Ag across 2.5’ (AFRI 52A05SE0022).
