Work History
Copper mineralization was found in the area as early as 1917. The Hoffman, Copper, Rae and Chalco cl (80001) were staked in Jun/56 and optioned to Asbestos Corp. which explored by prospecting and hand trenching. Restaked as part of Zebra cl 1-14 (Y6287) in May/66 by Callison Enterprises. The claims were optioned in 1967 to Venture ML and Anglo Western ML which explored by soil sampling in 1967 and vended the claims to Hart River ML in Dec/67. Hart River explored with grid soil sampling, trenching and 14.9 m of packsack drilling in 5 holes in 1971.
Capsule Geology
The claims cover Lower Proterozoic sedimentary rocks intruded by dioritic sill which are Middle Proterozoic in age. Asbestos Corp located several showings of chalcopyrite in veins and lenses in the area. The Hawley vein was found in 1966 by R.G. Hawley who was employed by Callison Enterprises to follow up earlier work completed by Asbestos Corp. The vein is located due south of the Zebra showing (minfile occurrence #116A 011) and is referred to as Zebra showings #3 and #10 in assessment reports #019103. Abbott (1997) examined the vein and reported the following.
A creek cut exposes a concordant lens of massive chalcopyrite with minor pyrite and quartz in steeply south diping shale in the Gillespie Lake Group (?). The occurrence is up to 30 cm across and at least 10 m long, with knife-sharp contacts. Both ends of the lens is associated with nearby quartz-carbonate veins and stringers with minor chalcopyrite and pyrite.
Sulfide-rich boulders up to 50 cm wide are fairly abundant in the main creek about 200 metres upstream from the main showing. The boulders consist of massive and brecciated vein quartz with up to 60% pyrite and small amounts of arsenopyrite. An arsenopyrite bearing specimen collected by Hawley, is reported to have assayed 5.14 g/t Au and 5.14 g/t Ag.
