Capsule Geology

The Cedar sheeted vein occurrence (Assessment Report 18597) outcrops in Nehalliston Creek below Highway 24, 10 (air) kilometres northwest of Little Fort.

The exposure consists of six, subparallel, milky white quartz veins trending 010 degrees and dipping 50 degrees west (Assessment Report 18597). The veins contain approximately 2 per cent pyrite and traces of galena. They pinch and swell, average 20 centimetres in width and are exposed in a moss-covered area of approximately 25 square metres. The highest assay was 450 ppb gold and 13.7 ppm silver (Assessment Report 18597). The veins are hosted in a fine- grained microporphyry which is probably a late and relatively felsic phase of the Triassic-Jurassic Dum Lake Intrusive Complex.

The Upper Triassic to Lower Jurassic Dum Lake complex is comprised of ultramafic and mafic plutonic rocks that could be part of an Alaskan-type intrusive body. The mafic portions of the Dum Lake complex are dominated by coarse to medium-grained gabbro and diorite but locally includes clinopyroxenite, monzogabbro, microdiorite and tonalite. The ultramafic portion of the Dum Lake complex includes an assemblage of variably serpentinized, locally talc and carbonate-altered rocks consisting of clinopyroxenite, wehrlite and dunite. The Dum Lake complex is truncated by granodioritic rocks of the Triassic to Jurassic Thuya batholith on its southeast side. On its eastward side, Dum Lake complex diorites and gabbros are in contact with massive andesites of the Upper Triassic Nicola Group and argillites, limestones and cherts of the late Paleozoic Harper Ranch Group (Fieldwork 2000).

The property was staked in 1985 by Craven Resources Incorporated. A program of geological mapping, soil geochemical sampling, panned stream sediment samples, lithogeochemical sampling, magnetic and VLF-EM surveying was carried out (Assessment Reports 13519 and 14477). In 1987, 21 kilometres of magnetic and VLF-EM surveying was completed by Craven Resources Incorporated. A prospecting program was completed by Pacific Comox Resources on the Cedar skarn (092P 026) in 1988 (Assessment Report 17709). Pacific Comox Resources completed 22 kilometres of magnetic and VLF-EM surveying in 1989 (Assessment Report 18612).
