The Joe 7 showing is located at 1160 metres elevation along a prominent northwest-trending ridge, 2 kilometres west of Blue Lake (Assessment Report 970).
The southern two-thirds of the property are underlain by Jurassic Kruger syenite and nepheline syenite. To the north are granodiorite and quartz diorite of the Middle Jurassic Similkameen intrusion. Jointly, these have intruded a northwest-trending roof pendant of Carboniferous to Permian Kobau Group metasediments and metavolcanics. Quartzite, phyllite, quartz-mica schist and greenstone are the dominant lithologies surrounding the showing. Alteration consists primarily of silicification with minor carbonate alteration. The greenstone has been more intensely propylitic altered to chlorite, epidote, carbonate, and potassic altered to potassium feldspar.
Low grade copper mineralization occurs in all rock types except syenite and nepheline syenite. Disseminated chalcopyrite and bornite with pyrite and magnetite comprise sulphides which appear to have been hydrothermally introduced in quartz and calcite veinlets up to 5 millimetres thickness. Malachite stains are also present in an abandoned pit at the Joe 7 showing. Copper mineralization appears associated with regional northwest-trending shears. A typical sample from one of these shear zones is reported to yield 17.14 grams per tonne silver, 0.373 per cent copper and 0.004 per cent molybdenum
