Mar 04, 2019 (P Bousquet) - The diamond drill hole intersected a sequence of metavolcanics, overlying a gabbroic intrusive. The mineralization seems to be located above the gabbro, in a rhyolite breccia.
Jan 16, 2023 (Therese Pettigrew) - Drill-hole L-13 encountered 3 different rock units between 200 and 345 feet (61 and 105.2 m). These units are: 1) diorite between 200 and 255 feet (61 to 77.7 m); 2) gabbro between 260 and 320 feet (79.2 to 97.5 m); and 3) andesite between 325 and 345 feet (99.1 to 105.2 m) (OFR5390 p. 33-3).

Mar 04, 2019 (P Bousquet) - The mineralization was discovered through sampling of the pieces of telescoped core at the District Core Library. Each piece represented a 3” section of core, per five feet of hole length. The best assay came from a sample at 320 ft, which contained 21290 ppm Ni, 1926 ppm Cu, 1480 ppm Co, 2.06 ppm pd and 0.32 ppm Pt.
Jan 16, 2023 (Therese Pettigrew) - Using backscattered electron imaging, cobaltite, chalcopyrite, native gold, kotulskite (Pd(Te,Bi)2-x), merenskyite (PdTe2), pyrite, pyrrhotite, pentlandite and sperrylite were identified in the core. The greatest concentration of kotulskite, merenskyite and sperrylite grains occur in the gabbro at 315 feet (96.0 m), 320 feet (97.5 m) and 321 feet (97.8 m), just above the andesite–gabbro contact. The second highest concentration of merenskyite and sperrylite grains is found in the sample at 245 feet (74.7 m), which appears to be a diorite, close to the gabbro contact. Eight gold grains occur with platinum group minerals at 321 to 315 feet (97.8 to 96.0 m) and 3 gold grains at 245 feet (74.7 m). Pentlandite and pyrrhotite occur in 6 of 8 polished thin sections. Kotulskite, merenskyite and sperrylite are associated with these sulphides and the wall-rock silicate minerals. Cobalt, in the 0.1 to 3 weight % range, was detected in all pentlandite. Chalcopyrite occurs in all polished thin sections. These sulphide, telluride and arsenide minerals were likely introduced by the hydrothermal fluids that formed the suite of silicate alteration minerals (OFR5390, p. 33-6).
