Township or Area: Tooms
Latitude: 47° 42' 57.69" Longitude: -82° 53' 16.9"
UTM Zone: 17 Easting: 358392.8 Northing: 5286464.65 UTM Datum: NAD83
Resident Geologist District: Timmins
NTS Grid: 41O10NW
Point Location Description: Old set-up for Granges drill hole SW48
Location Method: Field Visit with GPS
Access Description: Easy access to the area is possible from Highway 667 via the old Kormack logging road. From this road, a drill trail leads up to the collar. A new logging road just north of the drill trail tends to obscure the access to these drill trails.

Dec 07, 2005 (A Wilson) - The host rock has been described as a mixed assemblage of rhodacitic tuffs, rhyolite fragmentals together with chlorite and biotite schists. The unit has also been described as carbonatized mafic tuffs plus ash tuffs, with intercalated argillite, conglomerated and cherty horizons together with some ultramafic flows. There appears to be a strong similarity between this prospect and the Tooms Nickel prospect.

Jun 19, 2013 (A Wilson) - In addition to being disseminated in the host volcanic-sedimentary host rocks, pyrrhotite and pyrite occur in trails and semi-massive stringers within the various mineralized zones. Locally, pyrrhotite dominates over pyrite and can form up to 20% of the rock and is associated with minro amounts of disseminated chalcopyrite. Where pyrite is more abundant than pyrrhotite and forms up to 10% of the rock, chalcopyrite forms up to 1% of the rock. In such cases, the sulphides tend to be banded. Assays returned from diamond drilling completed by Granges were up to 0.08% Cu combined with 1.02% Ni. Several zones were intersected with weighted averages of 0.18%, 0.42%, 0.33%, 0.26% and 0.44% Ni over widths ranging from 3 to 15 m. With one exception, this zone contained negligible copper.
Jun 19, 2013 (P Bousquet) - Hole TN-93-05 drilled by Kennecott Canada Inc intersected 1.6 metre of intermediate to mafic tuff which returned an assay of 16 000 ppm Ni. The intersection was well mineralized with fine to medium-grained disseminated cubic pyrite interstitial to the fragments gradational contacts (T-3481).
