Point Location Description: AMIS Shaft location

Location Method: Data Compilation

Access Description: Follow Highway 588 to the intersection with the Paipoonge C line road, then drive 2.9 km along the C line road to an old non-driveable road, which extends to the SW for about 4 km and leads to a clearing, the former site of the stamp mill for the Rabbit mine. To the right of the clearing is a pond and beaver dam. The No. 2 shaft is situated 18.3 m SW of the water. The Rabbit Mountain Jr vein is 121.0 m NW of the No. 2 shaft.



Exploration History

1883: T.A. Keefer discovered the vein. By the end of 1885, the shaft had been sunk 17.4 m. There does not appear to have been development work done after 1886. 1955: Nanglora Mining and Exploration Company Ltd. drilled 2 DDH totalling 258.2 m.

Mineralization Comments

Feb 06, 2018 (Therese Pettigrew) - Tanton (1931) reported that 122 m NW of shaft No. 2 of Rabbit Mountain Mine, a shaft was sunk 22.9 m. The work that was done seems to have yielded little silver. The shaft is said to have been sunk on a vein 1.22-1.53 m wide in a diabase sill. The strike of the vein is approximately NE and dips 75 degrees to the SE. The vein minerals are calcite, white and amethystine quartz, green fluorite, sphalerite, chalcopyrite, and pyrite. OGS samples collected in 1984 near the adits returned assays of <0.01 opt Au, 0.1-0.48 opt Ag, 9-116 ppm Cu, 1130-44,800 ppm Pb, and 2140-11,520 ppm Zn, with up to 3% galena and sphalerite in the vein.
