May 31, 2022 (Therese Pettigrew) - Stringers of pyrite and subordinate chalcopyrite, up to 3 inches thick occur in intermediate metavolcanics (Shklanka, 1969). One annual company report from Jedder Gold Mines Limited describes the J. E. Derraugh showing to be a two hundred foot long quartz vein being from 4.0 to 4.5 feet wide with chip samples assaying 0.05 to 0.52 ounces gold per ton. (Assessment report 52I07NE0001). The 1998 prospecting program completed over the claim block located only sparse outcrop. The rock types encountered during the prospecting program include: massive and pillowed mafic volcanics, oxide facies iron formation, clastic metasediments and gabbroic intrusives. The dominant rock type is massive to pillowed mafic flows with lesser inter-bedded sedimentary rocks. The inter-layered volcanic and sedimentary rocks occupying the central portion of the claim and are flanked to the north and to the south by relatively thick sequences of mafic flows. Gabbroic sills/dykes are found at or close to the contacts between the sedimentary rocks and the mafic volcanic flows. Mineralization consists of minor fine grained disseminated pyrite found primarily within the volcanic rocks. Rare local minor chalcopyrite is associated with narrow quartz veining Samples taken in 1998 returned up to 136 ppb Au from a 20-30 cm quartz vein. Prospecting since the 1980s has been unsuccessful at locating the original, larger gold showing. The diamond drilling by Canadian Dyno Mines Limited intersected narrow widths of sphalerite and chalcopyrite hosted in pyrite - pyrrhotite bearing iron formation. (Assessment report 52I07NE2002).
