Point Location Description: Transfer

Location Method: Conversion from MDI

Access Description: Proceed along Highway 11-17 to Highway 588. Turn left (south) onto Highway 588 and proceed SW for 10 km. At this point, there is a gravel road with a gate near the entrance on the left (SE) side of the highway. Proceed on foot past the gate along the gravel road for 600 m to the Beaver Mine site. Follow the road past the Beaver Mine for a further 1.7 km. Turn left onto a small obscure trail and follow the trail for 750 m. An adit is located approximately 75 m SE of the trail at the base of a hill.

Exploration History

Pre-1890: a 52 m crosscut driven into the north-facing cliff to the Black Fox vein, and a winze sunk to a depth of 7 m. 1890: owned by the Beaver Milling and Mining Company. 1959: property acquired by Cairngorm Mines Ltd. 2018: Honey Badger carried out prospecting and sampling.

Feb 06, 2018 (Therese Pettigrew) - The Black Fox vein strikes north 80 degrees east from a small notch. In 1927, the mouths of two caved adits were noted about 150 feet NE of the notch and 20 feet below the base of the diabase sill. A dump, measuring approximately 50 feet by 5 feet by 7 feet, extends from the mouth of the adits. One adit appears to trend south 10 degrees east into the shale, the other south 35 degrees east. Above these at the base of a diabase sill, there is a pit 5 feet deep. No vein material is exposed in place near these workings. On the dump, however, are blocks of shale penetrated by veins up to 4 inches in width and consisting of white and amethystine quartz, calcite, and small amounts of sphalerite and pyrite (Tanton, 1931). In his 1890 report to the Beaver Milling and Mining Company, W.W. Russell noted that the argentite and native silver are spatially related to the higher concentrations of sphalerite within the composite vein. The greatest concentrations of silver mineralization were observed to occur within the upper part of the Rove Formation, near the contact with the overlying diabase sill. There is no record of production at the Black Fox vein site, and it is unlikely that any of the ore from the dump was milled or processed. An assay from a sample from the dump taken during the 1984 Hazards Land survey, however, showed the rock to contain 46 opt Ag. Sample 1099078 collected in 2018 by Honey Badger Exploration returned 7.09 g/t Ag, 0.86% Pb, 0.34% Zn (Assessment report 20000017904).
