Capsule Geology

The Woof 3 occurrence area is underlain by a northeast trending belt of Devonian and/or older? felsic volcanics (sericite and quartz-sericite schists) of the Woolford Creek unit of the Eagle Bay assemblage, bounded to the north and south by intermediate volcanics of the Devonian Skwaam Bay unit of the Eagle Bay assemblage. Felsic volcanics consist largely of fragmental rocks (tuffs, lapilli tuffs, breccias). Local hard, massive exposures may represent flows. Due to surface oxidation, fragmental textures are generally only recognizable in drill core. Felsic volcanics characteristically contain 1-5 per cent disseminated and fracture-fill pyrite. The belt of felsic volcanics thins dramatically eastward. Lineations in the area plunge shallowly to the west-northwest.

Surrounding intermediate volcanics consist of a fairly monotonous sequence of chlorite phyllites. At the south end of the area, the chlorite phyllites are hornfelsic and intruded by dikes of foliated granodiorite.

Minor argillaceous sediments have been identified in drill core along the southern felsic-intermediate volcanic contact. Minor disseminated and fracture-fill pyrite, chalcopyrite and sphalerite is present on surface and in drill core near this contact. Drill core from 1987 drilling was re-logged and re-sampled. Results include 0.58 per cent zinc over 4.14 metres, followed by 0.68 metre unmineralized, in turn followed by 0.40 per cent copper over 4.15 metres including 1.04 per cent copper over 1 metre (Assessment Report 20640, page 12).

In 1990, prospecting along the contact identified pyrite- chalcopyrite mineralization 350 metres to the east. A grab sample analysed 0.89 per cent copper, 17.6 grams per tonne silver and 0.20 gram per tonne gold (Assessment Report 20640, page 14).
