Geology Comments

Jun 10, 2014 (Mark Puumala) - The RJ showing is located within the Black-Pic Batholithic Complex. Mineralization consists of pyrrhotite, chalcopyrite and pyrite hosted by an ultramafic to mafic rock body described as hornblendite. Sulphides occur as disseminations, blebs and veinlets, similar to that found at the nearby Tyko occurrence. The RJ showing is associated with an induced polarization geophysical anomaly that was drilled by North American Palladium in 2006 and 2007 (AFRO 2.33676 and AFRO 2.36977). The most significant assays reported from this drilling were 1.05% Ni and 0.47% Cu over 6.2m from ddh TK06-005 (AFRO 2.33676). Mineralized surface grab samples collected by Tyko Resources Inc. during a 2011 prospecting program assayed up to 0.49% Ni and 0.93% Cu (AFRO 2.53317).

Lithology

Lithology Comments

Oct 21, 2014 (Therese Pettigrew) - This geological summary is compiled from information taken from Spence (2000, AFRO 2.21034) and Neilsen (2007, AFRO 2.36977): Regional-scale mapping by Milne (1968) indicated that the rocks in the area were predominantly granitic. The composition of the granitic rocks varies from granodiorite to quartz monzonite to tonalite. Prospecting and mapping by Spence (2000, AFRI 2.21034) indicated that granites contain numerous mafic to ultramafic xenoliths or fragments, some of which are mineralized. Most of the granitic rocks on the property contain variable amounts of mafic xenoliths. However, the granites immediately north of the RJ Showing contain very few, if any, mafic or ultramafic xenoliths. The mafic-ultramafic body intersected at the RJ Showing is quite large and may be considered an intrusive body as opposed to a large “raft” in the granites. Diabase dykes are found throughout the property and are readily identified on airborne magnetic surveys. Interpretation of the mag maps combined with reconnaissance mapping indicates that the dykes are relatively subvertical with strike orientations that vary from N-S, ENE and E-W. The major structural feature of the property is a very wide deformation zone (>4 km wide) in which the rocks have been fractured into angular fragments ranging in size from 0.3 m to blocks of 5 m. The lack of smaller fragments suggests a zone where brittle deformation had taken place with very little subsequent movement. The fragments and blocks have subsequently been in-filled and intruded by at least three felsic episodes during which the fragments were pushed apart and not deformed. The general strike of the fragmentation zone is 080°.

Mineralization

Mineralization Comments

Oct 21, 2014 (Therese Pettigrew) - Prospecting and mapping by Spence (2000, AFRI 2.21034) indicated that granites contain numerous mafic to ultramafic xenoliths or fragments, some of which are mineralized. These xenoliths are most visible at the Tyko Main Showing and can be subdivided into groups. The most important are medium-to coarse-grained, dark green ultramafics and mafics that vary in composition from hornblendite to biotite hornblendite to hornblende gabbro. These are not always mineralized, but are host to the vast majority of Ni-Cu mineralization seen on the property. Sulphide mineralization within these rocks varies from fine-grained disseminated to coarse-grained blebby. The sulphides consist mostly of pyrrhotite and chalcopyrite with lesser pyrite. The second group of xenoliths are referred to as amphibolites and are typically fine-grained, black to grey, weakly to moderately foliated, with small bladed amphiboles and are typically fine-grained, black to grey, weakly to moderately foliated, with small bladed amphiboles and a variable felsic mineral content. These rocks are usually barren except for minor amounts of pyrite. Some of the host rocks are altered to chlorite as well as serpentine and talc. The higher-grade samples consist of coarse-grained pyroxenite bearing appreciable to abundant disseminated and net textured pyrite, pyrrhotite and chalcopyrite and are strongly magnetic. Results from 2006 drilling: TK-06-003: 63.92-68.00 m - 0.511% Cu, 1.065% Ni, 0.024% Co, 0.243 g/t Pt, 0.123 g/t Pd, 0.003 g/t Au TK-06-004: 82.00-84.00 m - 0.506% Cu, 1.195% Ni, 0.023% Co, 0.129 g/t Pt, 0.128 g/t Pd, 0.008 g/t Au TK-06-005: 25.00-31.20 m - 0.466% Cu, 1.046% Ni, 0.019% Co, 0.203 g/t Pt, 0.122 g/t Pd, 0.018 g/t Au Results from 2007 drilling: TK07-001: 67.00-70.00 m - 0.01 g/t Au, 0.15 g/t Pt, 0.12 g/t Pd, 0.003% Co, 0.333% Cu, 0.389% Ni TK07-001: 138.50-142.60 m - 0.01 g/t Au, 0.06 g/t Pt, 0.04 g/t Pd, 0.000% Co, 0.221% Cu, 0.300% Ni TK07-002: 100.00-104.65 m - 0.01 g/t Au, 0.02 g/t Pt, 0.04 g/t Pd, 0.000% Co, 0.284% Cu, 0.434% Ni TK07-003: 105.50-107.00 m - 0.01 g/t Au, 0.16 g/t Pt, 0.13 g/t Pd, 0.012% Co, 0.376% Cu, 0.802% Ni TK07-006: 82.00-83.00 m - 0.05 g/t Au, 0.28 g/t Pt, 0.24 g/t Pd, 0.006% Co, 0.605% Cu, 0.336% Ni From the 2007 IP/Mag survey, it was determined that the RJ intrusion is not as continuous as first anticipated (Nielsen, 2007, AFRI 2.36977). DDH TK-16-002 returned 1.04% Ni and 0.23% Cu over 16.2 m (Assessment report 20000014345).
