Capsule Geology

The Province West zone lies 200 metres above the underground workings of the old Big Missouri Mine and occurs within the Upper Horizon which consists of several cherty tuff layers with dis- seminated sulphides to semi-massive sulphide lenses. The zone lies within south-southeast striking, moderately dipping andesite, agglom- erate and lapilli tuff, with interbedded cherty tuff of the Lower Jurassic Unuk River Formation. (See Big Missouri - 104B 046 for enhanced geology).

The Province West zone lies 200 metres west of and is much smaller than the Province East zone (see 104B 147). It consists of beds of mixed cherty tuff and sericitized andesite. Pyrite, sphalerite, galena, and minor chalcopyrite occur as patches, thin lenses, and disseminated grains within the bleached andesite-chert tuff zone.

The Province West zone likely contains reserve grades similar to the Province East zone, however the tonnage potential is quite small.
