Nov 21, 2014 (A Wilson) - Diamond drilling by Selco Exploration Co. Ltd. in 1968 returned intersections of 2.54% Cu, 14.96% Zn and 3.37% Ag over 49.3 ft; 6.26% Cu, 14.69% Zn and 4.96 % Ag over 18.8 ft and 25.35% Zn, 2.25% Cu and 4.47% Ag over 72 ft. 2006 Tribute Minerals Corporation 1 DDH @335 m. Best assays returned 1.59% Zn over 0.5 m.
Nov 15, 2022 (Therese Pettigrew) - Massive sulphide mineralization occurs in Early Precambrian rhyolitic tuffs. Mineralization consists of sphalerite, chalcopyrite, and pyrite. Sphalerite occurs in bands and lenses up to 30 feet thick. Three steeply dipping ore shoots have been outlined to a depth of 300 feet along an east-west strike length of 600 feet. Widths of ore shoots varies between 10 and 60 feet. Additional ore exists on the 600-foot level, and has been intersected by drilling below 700 feet. Fine grained cassiterite is widely disseminated in silicate gangue and sulphide minerals. Forty-five samples were taken systematically in an area 180 ft long and 30-40 ft wide on the 50 ft level and ranged from 0.-7 to 0.76% Sn, averaging 0.23% Sn (SMDR 00521).

Atkinson et al., 1991 | Production figures traced back to Atkinson et al., 1991 and to paper MDI files in the Red Lake office. Production tons appear to be accurate, but grades are somewhat questionable as the original source (paper MDI files) document only tons of metal concentrates produced, not grades. |
