The Carb occurrence is located at an elevation of approximately 1140 metres on a southeast-facing slope between Birk and Harper Creeks and approximately 2.9 kilometres northwest of the southwest end of North Barriere Lake.

Regionally, the area is underlain by the Graffunder Lakes, Skwaam Bay and Slate Creek units of the upper Paleozoic to lower Cambrian Eagle Bay Assemblage, which consist of micaceous quartzite, sericite-quartz schist, mudstone, siltstone, shale and calc-alkaline volcanic rocks. Local foliation strikes 135 degrees with a 5-degree northeast dip. The Cretaceous Baldy Batholith, consisting of quartz monzonitic intrusive rocks, lies to the north.

Locally, an argillaceous limestone hosts sphalerite mineralization.

In 1987, a sample from trench NTR-87-12 is reported to have assayed 12 per cent zinc over 0.40 metre (Assessment Report 19363).

Also at this time, rotary drilling to the south and southeast (holes NRD-87-02 and -06) yielded intercepts of up to 0.110 and 0.153 per cent lead with 0.183 and 0.150 per cent zinc over 4.6 and 9.2 metres, respectively, of silica-flooded and sericite-talc–altered muddy tuff, argillite and minor phyllite with disseminated pyrite, pyrrhotite and minor sphalerite (Assessment Report 17344).

In 1989, a rock sample (VA12291) assayed 5.2 grams per tonne silver, 0.177 per cent lead and 1.19 per cent zinc (Assessment Report 19363).

Work History

The area has been explored in conjunction with the nearby Percy (MINFILE 082M 219) occurrence and a completed exploration history can be found there.

In 1987, Noranda completed two rotary drill holes on the occurrence. No records are known for either of these holes. Two other rotary drill holes were completed to the south and southeast of the occurrence.

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 2013, the area was prospected and (rock, silt and soil) sampled as the Stellar claims.
