The Bunker Creek prospect is one of a number zinc-lead showings located in the upper Richards Creek valley.

Regionally, the Richards Creek valley is underlain by Devonian Stone Formation dolomites conformably overlain by Middle Devonian Dunedin Formation micritic limestones. The Devonian to Carboniferous Besa River Formation shale overlies the Dunedin Formation. This sequence is overthrust from the west by a panel of Stone Formation rock, which is in turn overthrust by Cambrian to Ordovician Kechika Group carbonates, Ordovician Skoki Formation dolomite and Silurian Nonda Formation dolomite and quartzite.

Mineralization, hosted within the underlying Stone Formation approximately 30 metres stratigraphically below the contact of the Stone and Dunedin formations, comprises fracture-controlled, irregular massive pods of marcasite, sphalerite and galena. White sparry dolomite and quartz-filled cavities are associated with the mineralization. The fracture fillings may coalesce into irregular networks of veins.

In 1973, diamond drilling yielded intercepts with estimated grades including 4.6 per cent zinc and 0.1 per cent lead over 3.0 metres (19.4 to 22.4 metres down hole) in hole C-1 and 6 per cent zinc over 1.5 metres (44.3 to 45.8 metres down hole) in hole C-3 (Property File – K.M. Carter [1972-08-29]: Drill Hole Record - RIC Group).

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. In 2008, Douglas Herriott prospected and sampled the area as the Red Cat property. No assays were reported.
