Aug 30, 2010 (A Wilson) - The deposit is hosted by a thick ultramafic body with a dunite core and peridotite margins. The ultramafic body has been interpreted as a channelized flow or sill. The underlying andesites exhibit patchy alteration and silica veining within 30 cm of the contact witht eh overlying pyroxenite.

Aug 30, 2010 (A Wilson) - Abraham (1953) Subsequent drilling revealed sulphide mineralization consisting of pyrrhotite, pentlandite, and chalcopyrite as disseminations and occasionally as veins at or near the north contact of the intrusive over a strike length of 1200 feet. ..... a zone 160 feet long, 9.3 feet wide and 280 feet deep with 1.46% Ni and with minor amounts of Cu, was outlined. The zone like the intrusive volcanic contact trends in an easterly direction and drops steeply south. Houle (2001) writes the mineralization occurs approximately 0.8 m above the basal contact within olivine pyroxenite and is composed of interlayered net-textured sulphides, disseminated sulphides and barren olivine pyroxenite. However disseminated mineralization always overlies net textured mineralization suggesting that the sequence youngs towards the south, consistent with the regional geology. The presence of barren komatiitic cumulate rocks within the main mineralized horizon and the apparent disruption of mineralized zones by olivine pyroxenites suggest the environment was quite dynamic and was characterized by successive replenishment of magma and sulphides into the channel. The mineralization occurs approximately 80 cm above the basal contact within olivine pyroxenite and is composed of intelayered net-textured sulphides, disseminated sulphides and barren olivine pyroxenite. A grab sample collected in 2000 by Hucamp Mines Limited returned 4.68 g/t Ni and 1.1 g/t Pt+Pd. Diamond drilling results from DDH LS-08-04 completed by Liberty Mines in 2008 returned 0.53% Ni over 73.45 m including 4.67% Ni, 0.16% cu, 0.273 g/t Pt, 0.874 g/t Pd and 0.021 g/t Au over 4m.
