The Dunedin showing is one of numerous zinc-lead showings located in the upper Richards Creek valley.

Regionally, the Richards Creek valley is underlain by a conformable sequence of Lower to Middle Devonian Stone Formation dolomite, Middle Devonian Dunedin Formation micritic limestone and Devonian to Carboniferous Besa River Formation shale. This sequence is overthrust by a panel of Stone Formation and Dunedin Formation strata, which in turn overthrust by a package of Cambrian to Ordovician Kechika Group, Ordovician Skoki Formation and Silurian Nonda Formation rock.

The showing, hosted by brecciated siliceous Dunedin Formation limestone near the stratigraphic contact with overlying Besa River shales, consists of barite with trace galena.

Work History

In 1972 and 1973, Cominco Ltd. completed programs of geological mapping, geochemical sampling and at least 16 diamond drill holes, totalling 952.2 metres, on the area as the Ric claims. No assays were reported. In 2008, Douglas Herriott prospected and sampled the area as the Red Cat property. No assays were reported.
