Work History

Staked as Jake cl 1-80 (Y16443) by Atlas Explorations Ltd in Oct/66. Restaked as Jake cl 1-80 (YA28765) in Jun/78 by F. Hastings.
Restaked by D. Brett as JK cl 1-42 (YB56362) in Oct/94. Brett carried out a small prospecting program in the fall of 1995. In Apr/96 Brett optioned the claims to Pacific Bay Minerals Ltd which carried out an helicopter-borne geophysical program, followed by geological mapping, prospecting and geochemical sampling programs later in the year.

Capsule Geology

The area has not been re-mapped by the Yukon Geology Program. A geological compilation by Gordey and Makepeace (1999) suggests that the area is underlain by a shallow marine, miogeoclinal sequence of carbonate and clastic sedimentary rocks. The rocks range in age from Upper Proterozoic to Mississippian and form part the Cassiar Platform. The mid-Cretaceous McEvoy granitic plug intrudes the sequence to the west.
Atlas Exploration mapped over 20 base metal showings on their claim block, most of which consisted of disseminated Cu, Pb and Zn in altered granitic rocks or in quartzite and chert. Selected samples assayed 82.3 g/t to 490.3 g/t Ag, 0.18 to 16.2% Cu and 0.2 to 9.2% Pb and up to 3.6% Zn.
Prospecting by Harman (1996) and company revealed a 1.5 m wide massive sulphide occurrence of pyrite, chalcopyrite, sphalerite, and minor galena in foliated, gossanous chloritic schist as well as several localities with gossanous boulders in float. Harman did not report any assays.
Pacific Bay re-mapped the property in 1996. They noted 7 base metal showings which appeared controlled by and localized along, major fault zones cutting miogeoclinal strata. Mineralization mainly occurs as weak to moderate disseminated sulphides commonly associated with various alteration mineral assemblages. The majority of the showings occur in fault or breccia zones associated with faults, although some sulphides are hosted within bull quartz veins. Exact stratigraphic units are uncertain, but Pacific Bay¿s field descriptions suggests that the mineralization is hosted in Silurian to Middle Devonian quartzite or chert.
The helicopter-borne geophysical survey outlined 3 large magnetic complexes, 4 conductive horizons and 1 resistivity low. Soil sampling outlined a 1.6 km long by 1.0 km wide anomaly centred over the main area of mineralization. The anomaly was strongly anomalous for Zn, Pb, Cu, Ag, Cd, V and Mo and weakly anomalous for Fe, Mn, Ni and Co. Rock sampling of the various mineralized showings generally confirmed historic values.
Pacific Bay theorized that mineralization on the claims is intrusive related and a porphyry style deposit may exist at depth.
