The Poly occurrence is located between Chipman and Solly creeks, approximately 3 kilometres north of the Chemainus River.

The area is underlain by sediments of the Mississippian to Pennsylvanian Fourth Lake Formation (previously the upper part of Muller's Myra Formation), Buttle Lake Group. The sediments consist of interbedded laminated chert, argillite and siltstone with beds of fine to coarse-grained tuff. The unit, particularly the cherty intervals, is locally cut by quartz veins and veinlets. A feldspar porphyritic diabasic to basaltic sill, likely coeval with the Upper Triassic Karmutsen Formation, invades the strata.

Argillite interbedded with a foliated tuff strikes west- northwest with a moderate northerly dip. Foliation has the same strike but has a steep northerly dip. The argillite contains finely disseminated pyrite and minor chalcopyrite. Limonite staining occurs locally.

In 1985 and 1986, E. Specogna completed programs of prospecting, rock sampling and four diamond drill holes, totalling 20.7 metres. In 1987, Canamin Resources completed a program of geological mapping and geochemical sampling. Samples from this zone assayed up to 1.0 gram per tonne silver and 0.056 per cent zinc (Assessment Report 16906).
