Point Location Description: Pits

Location Method: Data Compilation

Access Description: The site is accessible by driving west from matachewan to Christy’s Camps on Mistinikon Lake. From Christy’s Camps take a boat or canoe north to the bay on the west side of the lake in the north half of claim MR10321. A winding trail of about 2.5 miles leads from this bay to the small lake on the west boundary of the township on claim MR18745.

Lithology Comments

Apr 28, 2015 (A Wilson) - A gossan exists in a shear zone that strikes N60W and dips 60SW. In the gossan, disseminated pyrite and stringers of pyrrhotite are present in silicified fine-grained andesite.

Mineralization Comments

Apr 28, 2015 (A Wilson) - A streaky lean dissemination of pyrite and a few stringers of pyrrhotite (which is said to contain nickel) can be seen in the andesite. Several rusty patches observed at intervals along the ridge to the southeast suggest the possibility of a zone of weak sulphide mineralization trending in that direction. A group of 9 claims adjoin the Brookbank property to the east were held by Mr. Isador. On the south boundary of the northwest claim of this group a pit was opened up in a patch of heavy gossan. Massive and disseminated magnetite, lean pyrite and traces of chalcopyrite were observed by W.S. Savage. The mineralization sampled and encountered within the trench almost exclusively occurs within the olivine pyroxenite unit although trace amounts are noted within the gabbro and amphibolite, particularly at the contact between the two. The style of mineralization is localized or patchy. However, previous sampling done on the trench may have removed higher concentration, more continuous mineralization. The primary sulfide mineral is pyrite and it occurs as very fine- to fine-grained disseminated, veins, and locally weakly net-textured. Chalcopyrite and pyrrhotite were also noted in zones with higher sulfide concentrations. Nickel, copper and PGM concentrations are generally low, with the best assay results from the mapping program being 1133 ppm Cu (sample 46113). Ni concentrations are less than 250ppm.
