Access Description: Proceed west on Highway 11-17 to Highway 588. Turn left onto Highway 588 and proceed west for 10.3 km to the bridge over Silver Creek. Proceed 150 m west of the bridge to an old bush road on the left (south). Follow this road on foot for 150 m. Turn right (west) and traverse 25 m on a bearing of 250 degrees to Adit #3.
1885-6: The vein was discovered by T.A. Keefer. The Little Pig vein was worked by 3 crosscut tunnels, about 200 feet apart, driven into the base of the hill about 40 feet below the outcrop of the SE-dipping vein. From the ends of two of the tunnels, drifts were driven on the vein for an aggregate distance of 60 feet. 1931-33: Animikie Mines optioned the property. 1993: J. Redden conducted trenching.

Jan 30, 2018 (Therese Pettigrew) - The Little Pig vein is part of the West Beaver Mine, and is exposed 100 m south of highway 588, on the northern side of a hill of flat-lying shale overlain by a diabase sill. It is exposed for a distance of 400 feet along the northern face of the hill. It strikes north 77 degrees east and dips about 70 degrees SE. It occurs in a shatter zone 4 feet wide in flat-lying Animikie shale through which limy concretions up to 2 feet in diameter are distributed. Vein material makes up a little more than half of the material in the shatter zone. It consists of coarsely crystalline white calcite, colourless and amethystine quartz, green and purple fluorite, with sphalerite and smaller amounts of galena, pyrite, and argentite (Tanton, 1931). Silver mineralization is generally quite low in this vein (Maunula, 1979).
