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

Regionally, the area is underlain by chert, siliceous argillite and siliciclastic rocks of the Mississippian to Pennsylvanian Fourth Lake Formation (Buttle Lake Group) and volcaniclastic rocks of the Middle to Upper Devonian Mclaughlin Ridge Formation (Sicker Group). These rocks are intruded by granodiorite and quartz diorite of the Early to Middle Jurassic Island Plutonic Suite and gabbroic to dioritic rocks of the Triassic Mount Hall Gabbro. Undivided sedimentary rocks of the Upper Cretaceous Nanaimo Group locally overlay the previous units.

Locally, argillite interbedded with a foliated tuff strikes west-northwest with a moderate dip to the north. Foliation has the same strike but has a steep northerly dip. The argillite contains finely disseminated pyrite and minor chalcopyrite. Limonite staining occurs locally. Rhodonite is also reported in the area.

Work History

In 1985 and 1986, E. Specogna completed programs of prospecting, rock sampling and four diamond drill holes, totalling 20.7 metres. In 1985, a rock sample (P2) of fresh rhodonite, taken approximately 500 metres to the southeast of the plotted location of the occurrence, assayed 0.14 gram per tonne gold (Assessment Report 14919).

Also at this time, Abermin Corp. and Laramide Resources conducted a program of geological mapping, trenching, rock sampling and diamond drilling to continue testing the Coronation Zone (MINFILE 092B 129) and other reconnaissance targets on the Lara property including the Poly occurrence area.

In 1987, Canamin Resources completed a program of geological mapping and geochemical sampling. Samples from the occurrence assayed up to 1.0 gram per tonne silver and 0.056 per cent zinc (Assessment Report 16906).

In 2023 and 2024, Nova Pacific Metals Corp. conducted a three-dimensional interpretation of a previous completed airborne magnetic survey on the Coronation trend of the Lara property, including the Poly occurrence area.
