Jun 22, 2023 (Therese Pettigrew) - The mineralized zone comprises fine- to locally medium-grained gabbro to melanogabbro containing pervasive trace to locally 0.5% extremely fine-grained (0.1 to 0.2 mm) "pin-point" sized disseminated sulphides, including pyrrhotite and subordinate chalcopyrite. The highest Pd concentrations may correlate approximately with subtle slightly more foliated zones within the gabbro. Grab samples on the showing returned up to 0.6 g/t Pt+Pd. The two Roadcut holes were spaced approximately 100 m apart, were completed to test the anomalous surface Pt and Pd results located on the northwestern margin of the Roadcut Complex. DDH 23WL003 returned 0.49 g/t Pt+Pd over 10.50 m from 14 m depth, and DDH 23WL004 returned 0.46 g/t Pt+Pd over 14.40 m from 5.60 m depth. Initial interpretations suggest the holes intersected a single, continuous zone associated with a non-magnetic gabbroic border phase of the Roadcut Complex (Prospector Metals news release May 18, 2023). Samples collected in 2001 returned 216 ppb Au, 46 ppb Pd, and 10 ppb Pd (Assessment report 52H06NW2008). The Nosulf Showing was discovered in 2021 when the initial sample (D296515) yielded 0.203 ppm Pt, 0.395 ppm Pd and 235 ppm Ni from a sulphide-barren gabbro north of the road. A sample taken 40 m to the north (D296630) yielded 0.279 ppm Pt, 0.274 Pd and 118 ppm Ni
