During the prospecting-mapping campaign, numerous outcrops were mapped, all of them were of granite-tonalite, pegmatite, or diorite compositions. A minor peridotite and pyroxenite component was also observed in the boulders fields. Good glacial striaes were measured at two locations, and showed similar orientation N214-220. A quick recheck of the Hotish-2 kimberlitic boulders dispersion train was done. It showed the presence of rounded cm kimberlitic peebles from 0.4 to 1.4km down-ice (and down current of the Pepehsquasati River) of the Hotish-2 kimberlitic sill. Protected beaches associated with turns in the river usually host a good amount of these cm pebbles. The vicinities of the Hotish-3 occurence (ddh intersect) along a small lake were also investigated for kimberlitic peebles-boulders or outcrops, but none were found.
