Sep 29, 2014 (Therese Pettigrew) - There is a large WNW-trending deformation zone, the local portion of which is referred to as the Junior Lake Shear Zone, which is the most prominent structural feature in the area and is characterized by narrow discrete zones of intensely sheared rock displaying dextral rotation separated by relatively undeformed rock packages. The deformation zone can be seen as an aeromagnetic lineament which extends east and west of the Junior Lake property and appears to join the regional Sydney Lake-Lake St. Joseph Fault Zone to the north. Although the shear zone is slightly sinuous through Junior Lake, three of the mineral occurrences, Carrot Top, B4-7 and VW fall on a straight line. The length of the shear zone is uncertain, however a length of at least 10 km has been defined. Regional deformation is expressed as a west to WNW trending, subvertical to steeply north-dipping foliation and small-scale folding in the area and on most of the property. Regional metamorphism is lower amphibolite rank, increasing to amphibolite rank in the contact metamorphic aureoles of the batholiths (Routledge and Scott, 2010).

Sep 29, 2014 (Therese Pettigrew) - The VW deposit is a low-grade Ni-Cu ± PGE ± Au disseminated to veined sulphide deposit dominated by pyrrhotite, potentially of epigenetic, hydrothermal origin. Metallurgical flotation testing of a limited number of sample composites in 2006 indicated that there is potential to produce saleable Ni and Cu flotation concentrates. The VW deposit comprises five subvertical zones of generally 1-5% sulphides consisting of pyrrhotite-pyrite-pentlandite-chalcopyrite-magnetite ± sphalerite enclosed in a deformed assemblage of mafic volcanics, ultramafic volcanics, mafic intrusives, and metasedimentary rocks. Mineralized rocks are primarily foliated/sheared mafic metavolcanics, with lesser mafic intrusives and metasedimentary rocks. Sulphides occur as blebs and laminae on foliation planes, as breccia matrix, as replacement style net texture and fracture filling. Pyrrhotite is fine grained and carries minor pentlandite exsolved as very fine flames. Much of the pentlandite occurs as discrete grains associated with pyrrhotite. Chalcopyrite and pyrite occur as fine to medium grains. The subzones within the VW deposit are distributed over an area of approximately 150 m to 210 m north-south. The area has been drilled for 796 m east-west and 409 m north-south, with the deepest intercept at approximately 320 m. Subzones within the VW package, as defined at a 0.2% Ni cut-off, range up to 26 m in horizontal width and are generally separated by 30 m to 40 m of weak mineralization to barren rock. The subzones average 6.7 m in horizontal width and are contained in a 125-200 m wide shear (Junior Lake Shear) that dips steeply north. There are three styles of sulphide mineralization in the VW deposit: 1) thin laminae and veinlets following the foliation of the volcaniclastic rocks. The highest concentration of sulphides and grades are found immediately adjacent to dyke contacts. This is the most important style. 2) Pyrrhotite, pyrite, and chalcopyrite-mineralized volcaniclastic host unit. 3) Low grade mineralization up to 0.4% Ni occurring as fine blebs of pyrrhotite and pentlandite within ultramafic schist, peridotite and serpentine. Locally sulphides can reach 40-50%, however no massive mineralization has been noted. In addition to blebs/clots, lamina on foliation planes and veinlets, sulphides also occur to a lesser extent as breccia matrix, as replacement style net texture and as fracture filling. Pyrrhotite is fine grained and carries minor pentlandite exsolved as very fine flames as well as occluded pentlandite as discrete fine grains. Chalcopyrite and pyrite occur as fine to medium grains. Prospecting in 2005 found a grab sample that returned 0.45% Ni. 2008 drilling results included the following: DDH 0408-180: 299.0-300.0 m 1.01% Ni, 0.03% Cu, 0.04% Co; 313.26-316.0 m 2.19% Ni, 0.04% Cu, 0.08% Co. DDH 0408-185: 216.0-227.0 m 1.53% Ni, 0.07% Cu, 0.04% Co; 239.0-240.5 m 0.88% Ni, 0.03% Cu, 0.03% Co; 243.61-245.0 m 1.39% Ni, 0.13% Cu, 0.04% Co. DDH 0408-187A 269.2-271.6 m 1.14% Ni, 0.03% Cu, 0.03% Co; 279.38-280.8 m 1.60% Ni, 0.09% Cu, 0.04% Co (Routledge and Scott, 2010).
