Capsule Geology

The area is underlain by the Lower Cambrian part of the Eagle Bay Formation consisting of siliceous and graphitic phyllites, phyllitic limestone and greenschist. The metavolcanics and meta-sediments generally strike northeast and dip 10 to 40 degrees north-west. The rocks are cut by Late Cretaceous or Early Tertiary quartz-feldspar porphyry and mafic dykes with northerly trends.

The Spar massive sulphide layer trends northeast and dips 30 to 40 degrees to the northwest. The layer can be traced approximately 600 metres to the north where it is folded and truncated by a fault. The thickness of the layer is structurally controlled, and it is the less obvious phase 2 structures that control thickness, and not the west plunging phase 3 structures.

Mineralization comprises sulphides of silver, lead and zinc within metasedimentary rocks on the north limb of the Nitwikwaia synform. The showings occur within a dominantly metasedimentary succession (EBGs) of siliceous and/or graphitic phyllite, calcareous phyllite, streaky banded calc-silicate rock, limestone and quartzite. The metasediments are stratigraphically underlain by chloritic schists and greenstone (EBG). (Preto, et al in preparation). The succession that hosts these layers are lower in sequence than those at Mosquite King (082M 016).

The mineralization occurs as layers, lenses and pods of semi-massive to massive sulphides, generally within a siliceous gangue. The dominant sulphides are pyrite, galena, sphalerite, chalcopyrite and pyrrhotite. The sulphide horizons are generally well banded and conformable to the schistosity and where observed, to the bedding. Intense deformation of the rocks has caused discontinuity and marked variability in the widths of the sulphide horizons which tend to thicken in the hinge zones of folds.

The Spar mineralization occurs at the crests of several super-imposed monoclinal folds averaging 3 metres thick along a strike length of 365 metres in a northeast trend. The massive sulphide mineralization is localized in the crests of drag-folds with axis south 60 degrees west, flat dip and plunge at 10 degrees southwest. The central portion of the zone is primarily massive galena bordered by a "fringe" zone of galena, sphalerite, pyrite and pyrrhotite.

Spar was first discovered in 1927. In the 1960's Giant Metallics mapped the area and undertook some trenching and drilling. The property was acquired by Killick Gold in 1974. In 1976 Hesca Resources drilled 8 holes. It was optioned to Craigmont Mines in 1977 and 1978, Brinex Ltd. in 1980 and Noranda Exploration in 1984 and 1985.
