Geology Comments

Oct 21, 2014 (Mark Puumala) - The Tyko occurrence is located within the Black-Pic Batholithic Complex. The host intrusion is described in OFR 6005 (Schnieders et al. 2000) as a dark green, unaltered, medium- to coarse-grained hornblendite. Mineralization (up to 12% sulphides) consists of pyrrhotite, chalcopyrite, pyrite and pentlandite that occurs as blebs and interstitial fillings around hornblende grains (AFRI 42C14NW2004). Associated gangue minerals include chlorite, sausseritized plagioclase and quartz, which envelop the sulphide veinlets (Schnieders et al. 2000). Grab samples collected from the surface showing by the resident Geologist Program in 1999 assayed up to 3.82% Ni, 0.86% Cu, 624 ppb Pd and 444 ppb Pt (Resident Geologist’s Files, Thunder Bay). During a 2001 trenching and channel sampling program, Freewest Resources Canada Inc. reported assay values averaging 1.07% Ni, 1.2% Cu and approximately 1 g/t total PGEs within a zone 100 m long and 25 m wide (AFRI 42C14NW2004). Diamond drilling by North American Palladium during 2006-07 returned values of up to 1.09% Ni and 0.77% Cu over 4.15 m in ddh TK-06-001 (AFRO 2.33676).

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. Of interest at the Main Tyko Showing are the xenoliths of mafic rocks within the granitic hosts and the numerous later granitic dykes that crosscut all of the older rocks. 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 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 and can be up to 12-15% of the unit. 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. Discovery samples contained 4528 ppm Cu, 6896 ppm Ni, 1085 ppb Pd, and 840 ppb Pt. Samples taken by Resident Geologist B. Schneiders contained 3.82% Ni, 0.86% Cu, 624 ppb Pd, and 444 ppb Pt. Results from 2006 drilling: TK-06-001: 17.40-21.55 m - 0.765% Cu, 1.093% Ni, 0.011% Co, 0.417 g/t Pt, 0.423 g/t Pd, 0.070 g/t Au; TK-06-002: 30.15-31.61 m - 0.579% Cu, 1.021% Ni, 0.017% Co, 0.402 g/t Pt, 0.711 g/t Pd, 0.057 g/t Au. DDH TK-16-010 returned 1.06% Ni, 0.35% Cu, and 1.62 g/t total PGE over 6.22 m (Assessment report 20000014345). Sample 472003, collected during Palladium One's 2019 prospecting program returned 4.09% Cu, 7400 ppm Ni, 1190 ppb Pd, 1210 ppb Pt, and 108 ppb Au from a hornblendite with 15% pyrrhotite and pyrite (Assessment report 20000018199).
