The CC occurrence is located on the north side of Birk Creek at an elevation of approximately 720 metres and approximately 1.4 kilometres northwest of the west end of North Barriere Lake.

The area is underlain by metavolcanics and lesser metasedimentary rocks of the Eagle Bay Formation of Devonian to Mississippian age. The volcanics include felsic tuffs and flows, metamorphosed to quartz- sericite schists and quartz-chlorite schists. The metavolcanics are intercalated with and overlain by limestone, graphitic argillite and phyllite.

The rocks trend northwest, with a prominent foliation dipping moderately to the southwest and locally striking 100 degrees with a 20 degree dip.

Small stocks of fine-grained, porphyritic granodiorite to quartz diorite intrude the metavolcanics. The Cretaceous Baldy Batholith of quartz monzonite to granodiorite composition lies north of the area.

Mineralization at the CC showing comprises a thin band, 10 to 20 centimetres wide, of semi-massive pyrite, galena, sphalerite and chalcopyrite within a 1 to 2 metre horizon of siliceous pyritic schist enclosed within light silvery grey chlorite-sericite-quartz schist of felsic volcanic origin.

A sample from this zone is reported to have yielded 20.5 grams per tonne silver, 1.6 per cent copper, 0.8 per cent lead and 6.6 per cent zinc over 0.20 metre (Property File – unknown [unknown]: Report on the Iron Cap Group).

In 1976, a 30-centimetre sample from a trench assayed 3.1 per cent zinc, 1.7 per cent lead, 0.34 per cent copper and 16.8 grams per tonne silver, while separate chip sample assayed 0.55 per cent copper over 1.5 metres (Assessment Report 6202; Property File - Gower, S.C. [1976-11-01]: Geology Map of the Birk 1 and 2 Claims).

In 1978, a drillhole (BET-6), located approximately 200 metres northwest of the trenched area, yielded 0.32 per cent copper, 0.33 per cent lead, 0.66 per cent zinc and 8.2 grams per tonne silver over 1.5 metres (12.2 to 13.7 metres down-hole) of andesite with heavily disseminated pyrite (Assessment Report 6879).

In 1990, drillhole BC90-08, located 220 metres north of the trenched area, intersected a weakly mineralized quartz crystal tuff yielding 0.184 per cent copper, 0.186 per cent lead, 0.151 per cent zinc, 3.3 grams per tonne silver and 0.08 gram per tonne gold over 1.80 metres (Assessment Report 21208).

Work History

In 1951 and 1952, Kennco Explorations Ltd. completed programs of bio- and geochemical sampling, a 26.0 line-kilometre ground electromagnetic survey and seven diamond drill holes, totalling 550 metres, on the area as the Johnson property. In 1966, the Mining Corporation of Canada Ltd. explored the area.

During 1969 through 1972, Duncanex Resources Ltd. completed programs of soil sampling, geological mapping, geophysical surveys, trenching and seven diamond drillholes, totalling 711 metres, on the area. During 1976 through 1978, Cominco Ltd. completed a program of rock and soil sampling, geological mapping, trenching, 17.1 line-kilometres of ground electromagnetic and induced polarization surveys and six diamond drill holes, totalling 772.2 metres, on the area as the Bet 1-5 claims.

In 1980, Cyprus Anvil Mining Corp. completed a program of geological mapping, soil sampling and 22.0 line-kilometres of combined ground magnetic and electromagnetic surveys on the area immediately east as the Hall claims. In 1982, Preussag Canada Ltd. completed a program of geological mapping, geochemical (rock and soil) sampling, a 12.5 line-kilometre electromagnetic survey and a lone drillhole, totalling 120 metres, on the Bet claims. In 1985, Noranda Mining and Exploration Inc. completed a 280 line-kilometre airborne magnetic and electromagnetic survey on the area.

During 1989 through 1991, Falconbridge Ltd. completed programs of geochemical (rock and soil) sampling, geological mapping, 97.7 line-kilometres of combined ground magnetic, electromagnetic and induced polarization surveys, trenching and at least nine diamond drill holes, totalling 2619.2 metres, on the Bluff, Bet, Mac, Raven, Rust and Percy claims.

During 2005 through 2010, the area was prospected and (rock, silt and soil) sampled as the Stellar claims.
