Mineralization Comments

Oct 21, 2022 (Therese Pettigrew) - In mining claim 564419 porphyry and mafic metavolcanics outcrops were encountered. A series of trenches and pits along a 200 degree strike north of the creek were discovered. The mafic metavolcanics in these trenches were rusty, strongly sheared, locally folded, and contained sulfide bands <4mm and semi-massive blebs. The sulphides were <15% pyrrhotite, <5% sphalerite, <5% chalcopyrite, with local magnetite and pyrite. The samples from the trenches assayed as high was 0.36% Zn, 0.17% Cu, 0.04 Ni, 0.03% Co, 0.02% Pb, 1.9 g/t Ag, and 0.021 g/t Au (Assessment report 20000019719).
