The Pat West occurrence is hosted in Middle Jurassic (and/or Early Cretaceous?) intrusive rocks of the Three Sisters pluton.

The Pat West showings were discovered during a 2011 fieldwork program by the BC Geological Survey. Two rock samples were collected, and the area was mapped. The showings are subvertical, roughly east to northeast-trending zones hosted in the Three Sisters pluton and are spread over the entire local map area (Figure 3b, Fieldwork 2011). A one metre wide zone exposed on the easternmost ridge contains quartz plus pyrite plus/minus copper sulphide veins hosted in biotite quartz monzonite and quartz monzodiorite of the central felsic phase. One sample assayed 0.7 per cent copper and 0.7 gram per tonne silver (sample 11BVA14-82, Fieldwork 2011). The mineralized central and western gossanous exposures are larger in aerial extent (30 to 50 metres wide and 200 to 300 metres long), contain disseminated pyrite and/or quartz plus pyrite veins, and lack copper sulphides. An assay from the latter location (11BVA15-90) did not return any anomalous values. These above two samples are about 1.5 kilometres apart.

In 2012, Quartz Mountain Resources Ltd, on the Galaxie property, conducted systematic soil and IP surveys over eight high-priority grids and two target areas identified by the 2011 stream sediment and soil geochemical results. This work included an IP survey over almost the entirety of title 512878 and the southeastern third of title 604847.
