The Kumar showing is hosted in rocks of the Lower Jurassic Telkwa Formation, Hazelton Group. A small Eocene stock of the Coast Plutonic Complex intrudes the strata to the immediate southwest of the area. Extensive masses of quartz diorite of the Middle Jurassic Trapper Plutonic Suite intrude to the north, west and south.

The Kumar showing lies near the previously identified Full Moon Showing, and may in fact be the same zone. Exploration activity in 2007 involved hand removal of snow and talus to better expose the mineralization followed by the collection of 22 grab and chip samples. The zone appears to be fault controlled with a north to north-northwest trend and a moderate dip to the east. Mineralization consists of 1) malachite stained silicified andesite lapilli tuff with 2 to 20 per cent combined bornite-chalcopyrite in disseminated or veinlet form; and 2) Thin (centimetre-scale) galena-sphalerite-chalcopyrite veins which have a similar trend to the main bornite bearing zone. Results from 2007 sampling of the main bornite zone include two grabs (samples 07RTP495 & 07RTP415) containing 10.81 per cent copper, 8.03 grams per tonne gold and 123 grams per tonne silver and 23.71 per cent copper, 0.66 gram per tonne gold and 255 grams per tonne silver respectively (Assessment Report 29585). A grab sample from a thin (5 centimetre) proximal quartz-galena-sphalerite-chalcopyrite vein contained 1.60 grams per tonne gold, 323 grams per tonne silver, 11.00 per cent zinc, 8.96 per cent lead and 0.25 per cent copper (Assessment Report 29585).

The Boulder zone occurs about 750 metres to the northwest of Kumar showing and consists of a series of medial moraines flanked by two larger steep sided (right and left) lateral moraines related to the advancement of the New Moon glacier. Overall, the mineralized rocks constitute 1 per cent or less of the float within this corridor, but locally constitutes up to 5 per cent. Nearly all of the mineralized float is angular to subangular suggesting a locally derived source. Earlier prospecting and drilling by St. Joe failed to locate the source of the boulder train, but it was believed to lie beneath the New Moon glacier. Exploration in 2007 has not been able to confirm this.

Three styles of mineralization were noted at the Boulder zone:

a) massive galena/sphalerite with pyrite in silicified carbonatized and chloritized andesitic flows,

b) heavy specular hematite, chalcopyrite, magnetite and minor sphalerite in jasperoidal chert,

c) chalcopyrite and pyrite in a chlorite and epidote altered grey cherty host rock.
