The property is underlain by a sequence of interlayered and interlaminated chlorite schist, phyllite, quartz-sericite schist and minor amounts of skarnified limestone. These rocks are tenta- tively included within the Paleozoic Eagle Bay Formation (Map 56). The sequence is likely derived from mafic to intermediate volcanic and volcaniclastic rocks.
The metavolcanics and metasediments are intruded by diorite to granodiorite dykes ranging from a few centimetres to tens of metres in thickness.
Pyrite, chalcopyrite and pyrrhotite mineralization is dissemi- nated and semi-massive within felsic to intermediate metavolcanics and graphitic argillite. Mineralization occurs along the south shore of North Barriere Lake and was intersected in a drill hole 750 metres south east of the lake. The best intersection in the drill hole was 0.16 per cent copper over 1.5 metres at 82 metres depth (Assessment Report 7254).
In 1971, Noranda Exploration Company Limited completed a geochemical soil survey, electromagnetic survey, and a diamond drilling program over the property containing the occurrence.
