Dec 07, 2005 (C Salo) - Massive biotite and biotite-hornblende granite and metasedimentary migmatite. Anorthosite being the main rock type containing mineralization zones. Other rock types observed are diorite, hornblende-mica schist and pegmatite. Strong shearing with a trend of N-60-W. The anorthosite in which mineral showings occur has a known extent from north to south or more than three quaters of a mile. The east-west extend having a possible length of over a mile. Three shears zones which are roughly parallel, striking N-70-W and N-60-W with a uniform steep dip to the northeast, have been exposed in pits. Mineralization consist of cp, pyh, pn, and minor amounts of py, occuring a blebs and disseminations in the anorthosite and horneblende - mica schist. Diorite in contact with pegmatite heavily minearlized with cp in pit #1. Sampling from trenches, Cu from 0.32% to 1.87% and Ni from 0.02% to 0.14%.

Jan 29, 2016 (A Mitchell) - The main rock type in the area containing the mineralized zones is anorthosite consisting of relatively large crystals of plagioclase feldspar with hornblende and augite. The anorthosite has been fractured by strong shearing which has a general trend of n-60-w. The other rock types observed in this area are diorite, hornblende-mica schist and pegmatite. The anorthosite in which the mineral showings occur has a known extent from north to south of more than three quarters of a mile. The east-west extent has not been established but prospecting to date would indicate a possible length of over one mile. The three shears are roughly parallel, the most northern where exposed in Pit No. 1 striking n-70-w and the other two striking n-60-w. The shears are interpreted to have a uniform steep dip to the northeast. The intensity of the shearing does not show to any marked degree on the undisturbed surface of the rocks and is only fully in evidence after blasting has taken place. The strongest 'shearing' is on the south zone, exposed in pit no 3 where both the diorite and the hornblende - mica schist show folding in both the horizontal and vertical planes. In pits no 1 and 2 shearing is evident but folding is not present. The mineralization consists of cp, po, and minor py. It occurs as irregularly distributed blebs, and as disseminations in the anorthosite and the hornblende-mica schist. Diorite in contact with the pegmatite in Pit No. 1 is heavily mineralized in cp.

Dec 07, 2005 (C Salo) - Sulphides occur as blebs and disseminations in Anorthosites and hornblende-mica schist. Cp occurs in diorite in contact with pegmatite. Mineralization consist of cp, pyh, pn, and minor amounts of py, occuring a blebs and disseminations in the anorthosite and horneblende - mica schist. Diorite in contact with pegmatite heavily minearlized with cp in pit #1. Sampling from trenches, Cu from 0.32% to 1.87% and Ni from 0.02% to 0.14%.
