At the Ben 1 showing on the Pavey property, two trenches expose stratabound disseminated sulphides near Pavey, 60 kilometres south of Whitehorse, Yukon.
The Pavey property (104M 002, 104M 028, 104M 038-47) covers gold and silver mineralization in shears and quartz veins related to several strong north and northwesterly trending faults. DuPont held the Gaug claims over the area presently covered by the Pavey 1-4 claims from 1981 to 1986. During 1982 and 1983 DuPont and Texaco completed geological and geochemical surveys. They located several old adits in a gully. In 1983, Texaco Canada staked the Ben 1-4 claims and performed geological geophysical and geochemical surveys. In 1990, Lodestar Explorations Inc. tested the showings on the Pavey property and the Skarn (104M 085) and Cowboy (104M 086) showings were discovered.
The claims are underlain by layered sedimentary, volcanic and metamorphic rocks intruded by granitic bodies and porphyry dikes. The Ben fault is a northwest trending structure that cuts argillites and metamorphic rocks in the area.
The showing comprises sulphides hosted in schist of the Devonian to Middle Triassic Boundary Ranges Metamorphic Suite. The metamorphic rocks constitute a fault-bounded zone about 1.0 kilometre wide, with Lower Jurassic(?) volcanics to the west and Upper Triassic Stuhini Group volcanics to the east.
The sulphide-bearing zone is about 1 metre wide and parallels the foliation between a shear zone and linear trend of irregularly-shaped quartz boudins. The zone is traceable along strike for 20 metres, with both ends covered with till. Sulphides include galena, sphalerite, stibnite, arsenopyrite, pyrite, and pyrrhotite.
A chip sample across 0.96 metre of the mineralized zone assayed 108.1 grams per tonne silver and 0.32 gram per tonne gold (Assessment Report 12554). In 1991, a trench sample (99109), from arsenopyrite-stibnite-galena veins, 1.5 to 10 centimetres wide, assayed 1.47 grams per tonne gold over 2.0 metres (Assessment Report 20581).
Refer to the Skarn prospect (104M 085) for a detailed history of the Pavey property.
