The P occurrence is located approximately 500 metres south east of the Alouette River, and 1.2 kilometres due south of the south end of Alouette Lake.

The majority of the region is underlain by granodiorite to diorite intrusions of the Jurassic to Cretaceous Coast Plutonic Complex. Roof pendants of the Paleozoic Twin Island Group and Jurassic Harrison Lake Formation occur throughout the area.

Locally, sparse sulphide mineralization is exposed in a 9-metre wide outcrop. The showing is underlain by dioritic intrusive rock, comprised of coarse-grained pyroxene and feldspar, within the Jurassic to Tertiary Coast Plutonic Complex. Medium-grained Late Jurassic quartz diorite and granodiorite outcrop nearby. The dioritic outcrop is cut by a northwest-trending zone of fault gouge 0.15 to 0.60 metre in width. The dioritic intrusive and the fault gouge are mineralized with disseminated pyrrhotite, pyrite and locally chalcopyrite.

Three grab samples assayed up to 0.17 per cent copper and 3.77 grams per tonne silver (Property File - Stevenson, W.G., 1975). In 1996, grab samples assayed up to 0.167 per cent copper (Assessment Report 24551).

In 1970, Javelin Mines completed a program of geological mapping, soil sampling and 9.6 line-kilometres of ground magnetic surveys on the area as the P and JA claims. In 1996, the area was prospected as the Dawn 1-3 claims. In 2003, the area was prospected as the Birch property. In 2005, Mineral Hill Industries completed 1.7 line-kilometres of ground electromagnetic and magnetic surveys on the area as the MR property. In 2010 and 2014, ground magnetic surveys were completed on the area as the Bluestone claims.
