Work History
Staked as part of 230 MR cl (YA66451) in Jul/81 by Regional Res L, which explored with mapping, airborne mag and EM surveys, geochem sampling and hand trenching in 1981-82. In 1983, Regional entered a joint venture with Getty Can Met L, which performed bulldozer trenching in 1983-85. Regional's interest was transferred to Fairfield Mls L, which drilled 22 holes (2413 m) in 1986.
Capsule Geology
The area of interest is underlain by a Lower Cambrian sequence of quartzite, intercalated graphitic and calcareous phyllite and limestone. Mineralization consists of four zones of smithsonite- and hydrozincite-bearing oxide float and gossanous quartz-mica phyllite, or iron- and manganese-rich oxide float.
Trenching in Area 2 uncovered 5.1% Pb, 2.0% Zn and 3.4 g/t Ag across 20 m, while replacement oxide bodies with remnant sulphides were exposed in Area 3 at the contact between the upper clastic and limestone unit and underlying metasedimentary rocks. Two specimens assayed 4559.9 g/t Ag and 80.1% Pb, and 23.6% Pb, 730.3 g/t Ag and 1.1 g/t Au. The best chip samples assayed 8.8% Pb and 51.4 g/t Ag across 1.5 m and 5.5% Zn across 9 m.
