Exploration History

1967: Armac Securities and the Tooms Nickel Syndicate carried out a program of geological mapping, a combined VL and HL electromagnetic survey. The layout of the geophysical work suggests that it was a follow-up to an airborne survey. Diamond drilling tested anomalies to the east of this prospect. 1977: Granges Exploration carried out an exploration program over several years in the area which consisted of ground geophysics on a number of grids followed by diamond drilling. Two grids #5 and #35 covered the prospect. During this work base metal mineralization forming this prospect was discovered when two holes (#SW3 and SW102) which returned copper nickel grades up to 0.18% Cu combined with 0.55% Ni. Weighted averages are 0.24% Cu and 0.27% Ni. 1981: Messrs Innes and Karvinen prospected the area for gold and obtained anomalous values in some old core. 1982: Quinterra Resources staked ground covering the claims and carried out a till sampling program south of the prospect looking for gold with some success. In the following year a ground magnetometer survey was carried out over the prospect then in 1984 an airborne magnetic and VLF electromagnetic survey was flown over the whole claim group. 1985: The Canadian Nickel Company optioned the property and carried out a reverse circulation drilling program to sample the overburden. No samples were obtained in the vicinity of the nickel prospect described here. 1992-93: Kennecott Canada acquired the property and carried out an exploration program in the search for nickel. Work consisted of magnetic and HL electromagnetic surveying, geological mapping and prospecting. Follow-up diamond drilling consisted of one hole targeted at this prospect which failed to duplicate the work carried out by Granges. However, the Kennecott hole was stepped well back from the original Granges holes. 2002: Canabrava Diamond Corporation – AEM, AMag, DD – 1 – 120m, Pr, Samp. 2008: Benton Resources Inc. – AEM, AMag.

Lithology

Lithology Comments

Dec 07, 2005 (S Fumerton) - The mineralization appears to be hosted in a relatively thin sedimentary / volcanic unit located between a volcanic gabbro to the south and ultramafic volcanics to the north. The ultramafics which consist of a number of flows are variably serpentinized and steatitized (carbonate-talc alteration). The mixed sedimentary volcanic unit has been described as:- 1) black greywackes, cherty quartzites, andesite tuffs. 2) rhyodacite tuffs. 3) siliceous tuff, brecciated dacite tuff. 4) argillite, chert. The volcanic gabbro is foliated with chlorite rich streaks and contains a number of chloritic shear zone. A number of small felsic dykes and sills have intruded these rocks. Generally there appears to be similarities between this prospect and the Tooms Nickel prospect.

Mineralization

Mineralization Comments

Jun 20, 2013 (S Fumerton) - Disseminated and wispy trails of pyrrhotite form up to 15% of the mineralized sedimentary - volcanic horizon. Disseminated pyrite and magnetite occur in minor amounts as does chalcopyrite to a lesser extent. Pentlandite occurs as discrete grains where the total sulphide content is high.

Dec 07, 2005 (A Wilson) - Assays obtained from core drilled in 1981 returned copper-nickel grades up to 0.18% Cu and 0.55% N over 3 ft. Weighted averages are 0.24% Cu and 0.27% Ni. Other samples returned values of: 1.00 g/t Au. Grab samples taken by the OGS in 1994 returned values of 0.04 g/t Au, 0.8 g/t Ag.

Geologist: W Karvinen

Notes: The Granges Exploration drill camp located on Sylvanite Creek in Tooms Township was visited. The camp is located on the Betty Lake road, 10 miles north of Kormak and 48 miles from Chapleau. To date a total of 10 hole (approx. 1900') have been drilled to test potential airborne geophysical anomalies. The company is using two drills, one of which is being moved and serviced by helicopter. The camp will be moving to Sultan to complete the 40 or so holes planed for the remainder of the winter. Core from all the holes except No. 9 were briefly examined. Except for holes SW-5 and 10, which were mainly in argillaceous sediments containing graphitic horizons, the main rock types encountered in the holes were mafic tuff, mafic basalt and felsic volcanics with intercalations of cherts and tuffaceous sediments. Narrow sections (approx. 10') of disseminated and massive lenses of pyrrhotite and some pyrite-cpy were intersected. The most interesting mineralization occurs in hole SW-3 which cuts through a thick section of cherts and tuffaceous sediments. In the cherts, disseminated to massive lenses of pyrrhotite and chalcopyrite occur over 25'. The host rocks and mineralization are very similar to the gold bearing cpy-po mineralization at the Amoco gold prospect at Detour Lake. As is so typical of the Swayze Belt, all interesting mineralization intersected in these holes are closely associated with sediments and chert horizons. ( PRECIS )
