11/04/2019 (T Pettigrew) - Two old trenches, located on the property, uncovered pyrite and chalcopyrite mineralization within a series of quartz carbonate veins, hosted by a mafic sericite schist. The trenches uncovered a series of quartz-carbonate veins hosting abundant pyrite and chalcopyrite, the latter oxidized to malachite. Grab sample 277 from one of the quartz carbonate veins varying between 7 and 15 cm wide, assayed 0.053 oz/t Au, 2.26 oz/t Ag, 6.7% Cu and 4% Zn (Assessment report 42E12SW0061). DDH SS8802 returned 0.021 oz/t Au, 0.06 oz/t Ag, 0.052% Cu, and 0.027% Zn over 1.9 ft. DDH SS8803 returned 0.006 oz/t Au, 0.06 oz/t Ag, 0.5% Cu, 0.016% Zn over 1.8 ft. DDH SS8807 returned 0.238% Cu and 0.019% Zn over 0.6 ft, and 0.07 oz/t Ag, 0.145% Cu, and 0.03% Zn over 2.0 ft. DDH SS8808 returned 0.032% Cu, 0.286% Zn over 2.0 ft; 0.09 oz/t Ag, 0.154% Cu, 0.057% Zn over 1.0 ft. The best mineralization occurred in strongly silicified and sheared mafic to intermediate metavolcanics with pyrite and chalcopyrite (Assessment report 42E12SW0063).
