Work History
Discovered prior to 1907 and explored by hand trenching. Staked as Jac cl 1-8 (Y8032) in May/66 by J. Smith, who then staked B.Jac cl 1-8 (Y8423) and Go Jac cl 1-8 (Y8431) to the north and south in Jun/66. In Nov/66, R.A. Granger staked Rag cl 1-2 (Y11311) on the eastern edge of the existing claim group probably covering the old hand pits and trenches.
In Feb/67 the claim group was optioned to Rexony Mining Company Ltd, which subsequently assigned the option to Pine Lake Mining Company Ltd. Pine Lake then staked Tea cl 1-16 (Y11894), Mtc cl 1-4 (Y11996) and Mtc cl 5-28 (Y12104), also in Feb/67, expanding the claim group to the east and carried out ground and airborne magnetometer surveying, tote road construction, bulldozer trenching, geological mapping and drilled 9 holes (826.9 m) later in the year.
Restaked as Kart cl 1-16 (Y62325) in Sep/71 by Caltor Syndicate (Rayrock Mines Ltd, Ashland Oil and Gas, Canadian Industrial Oil and Gas), which in Apr/71 had staked Pine cl 9-56 (Y60444) to the east. In 1972, the company carried out geochemical sampling, EM 16 geophysical surveying and geological mapping.
Restaked as Pilon cl 1-24 (Y79518) in Jul/74 by N. Barnett; as Ron cl 1-2 (YA23053) in Aug/78 by R.A. Granger; and as Ddl cl 1-16 (YC08325) in Oct/97 by Nordac Resources Ltd.
In 1998 Nordac carried out geological mapping, prospecting, hand trenching and geochemical sampling.
Capsule Geology
Four small skarn showings containing magnetite with minor bornite and chalcopyrite are found 1.5 km east of Lake Laberge. These occur at the contact of Late Triassic Lewes River Group limestone and argillite with several small mid-Cretaceous aged feldspar porphyry stocks. Three holes (98.1 m) were drilled through the skarn-intrusive contact in 1967, but average mineral content was less than 0.1% Cu equivalent.
The stocks show weak hydrothermal alteration with minor quartz veining containing chalcopyrite and molybdenum and represent a second type of mineralization. Sampling in 1998 of this porphyry style mineralization returned only background to weakly anomalous Cu values.
An intense magnetic anomaly on the northeast side of the lake was explored with 6 holes (728.8 m) but drilling found only magnetite in highly altered argillite and volcanic rocks, possibly of the Middle Triassic Joe Mountain Formation.
Sampling by Nordac of the old pits and trenches which exposed narrow veins and small lenses (up to 5 cm thick and about 40 cm in diameter) of semi massive to massive pyrite and pyrrhotite with lesser sphalerite, chalcopyrite and galena within a band of highly oxidized skarn, returned average values of 2.9% Zn, 0.17% Pb, 2.5% Cu, 66.9 g/t Ag and 9.1 g/t Au from seven grab samples. Chip samples from the same area returned only weakly anomalous and suggests that the mineralization is erratically distributed.
