Work History
Staked as White cl (YA99886) in Mar/87 by Mountain Province Mg Inc, which performed mapping and geochem surveys later in the year. Whyte cl (YB10202) were added to the southeast in Dec/87. Bulldozer trail construction, excavator trenching, IP and magnetometer surveys were conducted on the claim group in 1989.
Mountain Province conducted a 23 hole (1548 m) NQ diamond drill program on the White claims in Aug and Sep/93.
Capsule Geology
Three silver and gold occurrences occur in Lower Cambrian carbonate rocks. The Lake Zone, a 7 cm northeast-striking massive sulphide vein in Cambrian dolomite, is surrounded by a large polymetallic soil anomaly. A specimen of massive sulphide contained 1256 g/t Ag, 0.45 g/t Au, 58.0% Pb, 1.0% As and 0.4% Cu. A specimen containing disseminated galena returned 86.4 g/t Ag and 3.1% Pb while limonitic grab samples contained up to 0.8 g/t Au and 2630 ppm As.
The West zone consists of a layer of of limonite, locally stained with malachite and scorodite, immediately underlying green mudstone. Specimens of limonite assayed up to 5.8 g/t Au, 78.0 g/t Ag, 1.9% As, 0.2% Pb and 1.4% Cu. Associated siderite contained arsenopyrite, chalcopyrite, pyrite and pyrrhotite and assayed up to 1.2% Cu and 4.5% As. Diamond drilling in 1993 in this zone located low grade gold mineralization of up to 1240 ppb across 0.50 m. The gold is associated with two types of mineralization: massive pyrite-arsenopyrite lenses within a west-dipping shear zone; and a linear, northwest trending zone of secondary iron carbonate-quartz-chlorite alteration or replacement in the upper part of Lower Cambrian strata. The carbonate-quartz-chlorite zone contains disseminated pyrite, pyrrhotite, arsenopyrite and chalcopyrite with minor galena and sphalerite.
The East zone consists of siderite-pyrite-arsenopyrite veins which cut Cambrian limestone. Vein specimens assayed up to 41.8 g/t Au and 31.0 g/t Ag while chip samples returned 2.1 g/t Au across 3.7 m, and 12.2 g/t over 2.1 m. The 1993 drill program intersected 6 metres of carbonate-quartz-chlorite containing disseminated sulphides but almost no gold.
