Nov 22, 2017 (R Tuomi) - 1970 drilling best intersection assayed 0.38% Cu and 0.02% Ni over 1.2 m. Mineralization included pyrite, pyrrhotite and chalcopyrite. Sheared mafic metavolcanic rocks only lithology intersected. Silicification predominant alteration type. 1990: Chip samples assayed: 2.15% Cu over 2 m; and 1.55% Cu over 1.5 m. Host rock was sheared mafic metavolcanic rocks and gabbro.
Nov 22, 2017 (Therese Pettigrew) - Fine-grained basalt underlies an area south of Kite Lake. Near the southernmost tip of Kite Lake, an east-striking zone of schist and breccia, from 1-2 m wide and dipping south at from 50-70 degrees contains some carbonate and one or more quartz veins and lenses with a maximum width of 45 cm. The quartz is fractured, encloses minor silicified basalt, and contains abundant chalcopyrite and pyrite in and near some of the fractures. Two shafts about 30 m apart have been sunk on the zone. A chip sample across 50 cm of the mineralized quartz vein at the east shaft assayed 1.93 opt Au. A third shaft was put down a further 75 m t the east. A fourth shaft was sunk on a separate zone approximately 100 m to the SW. The best intersection reported from DDH 70-2 where a 3.8 ft interval from 89.0-92.8 feet assayed 0.38% Cu, 0.02% Ni, 0.06 opt Au and 0.10 opt Ag. McLaren for Rexora in 1950 wrote that "two veins, each about 500 ft. long are found in a wide shearing . . . four shafts were sunk in the early work to various depths on these veins". McLaren also stated that a bulk sample was taken by Rexora, partly at the 50' level at one shaft and partly from surface. The pulp from this bulk sample was shipped to a number of assayers with highly variable results. Of 15 separate assays the gold assayed at 0.22 to 3.28 opt Au, the silver assayed 0.71 to 4.26 opt Ag, and 2.37% to 11.28% Cu (AFRI 52E09SE0012). Sample 57906 collected by A. Mowat near the No. 2 shaft in 2011 assayed 1.260% Cu, 11.55 ppm Au, and 20.1 ppm Ag. The best nickel assay was 125.5 ppm Ni from sample 57907 (AFRI 20000007065). Pyrite, pyrrhotite and chalcopyrite mineralization occurs in silicified and sheared Early Precambrian andesitic volcanic rocks.

Geologist: Ethan Amyotte
Notes: Visited a newly stripped exposure 20m SE of the shaft. Exposed is a east trending south dipping (78°) 0.5m unit of carbonate altered mafic schist, bordered on the footwall by a silica altered schist and hanging wall by mafic flow rocks with quartz stockworking. A sample was collected of each rock type.
