Capsule Geology

The Himiomo showing is located on a ridge separating Dokdaon and Strata creeks, approximately 12 kilometres east of the Stikine River.

The area is underlain by stratified and intrusive rocks belonging to the Middle Jurassic Stikine Terrane. Stratified rocks consist predominantly of Upper Triassic Stuhini Group massive to thick- bedded, pale to medium green, aphanitic to porphyritic mafic volcanic flows with subordinate interbedded tan weathering siltstone and mudstone. These have been intruded by quartz monzonite, granodiorite and quartz diorite plutonic rocks and smaller Early to Middle Jurassic syenite and diorite/gabbro stocks.

Locally, mineralization occurs as disseminations and patches of pyrite within altered volcanic rocks and several narrower structural zones (up to 3 metres wide) containing pyrite and chalcopyrite bearing quartz veins and veinlets ranging in width from 2 to 12 centimetres. Sulphide content is variable, ranging from 2 to 40 per cent and the dominant species is also variable, with chalcopyrite generally being the more abundant of the two.

In 2005, Strategic Metals Limited optioned the property and completed an exploration program of geological mapping, geochemical sampling and prospecting. A pseudo chip sample, across a 7 metre wide zone, of moderate pyrite mineralization returned 0.13 per cent copper and 1.7 grams per tonne silver. Similarly, specimens containing up to 25 per cent sulphide content yielded 0.26 per cent copper and 2.6 grams per tonne silver. Also in 2005, a composite sample of seven veins occurring in a 3 metre wide fracture zone returned 6.6 per cent copper and 65 grams per tonne silver (Assessment Report 28228).
