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.

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).

Mosquito King comprises a number of thin, laterally extensive massive pyrrhotite layers, with locally high precious metal content in a highly deformed and metamorphosed calc silicate gneiss succession. Potassic and siliceous alteration are reflected in silicified sericitic zones in the immediate hanging wall.

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 Mosquito King showings occur as discontinuous stringers, lenses and disseminations over an area about 1000 by 500 metres. Mineralized widths vary from less than a metre to over 6 metres.

Drill indicated reserves are 33,744 tonnes grading 13.3 grams per tonne silver, 0.83 per cent lead, and 2.09 per cent zinc; an additional 4716 tonnes grading 19.8 grams per tonne silver, 2.6 per cent zinc, and 1.38 per cent lead (Statement of Material Facts 28/01/85, Killick Gold Company Ltd.)
