May 27, 2016 (A Wilson) - Copper mineralization was intersected in 6 holes (Midrim Mining) with the widest intersection of 0.31% Cu over 6.85 m. Assays from the samples returned copper values ranging from 0.13% Cu over 0.45 m to 1.44% Cu over 0.45 m. A 2.34 m section of core from DDH #7 assayed 0.13% Cu. The project was very successful, a large area of felsic volcanic rocks (150m by 75m) hosting disseminated chalcopyrite, returned highly anomalous copper values as high as 1.73% Cu. A 200 metre long magnetic high anomaly is roughly coincident with the area of anomalous copper mineralization. Mineralization occurs as quartz-carbonate veins, disseminated Cu, and Cu fracture filling. The mineralization is hosted within dacites, rhyolites, and schistose volcanic rocks. Alteration noted in drilling south of the project area includes chlorite, sericite, and silicification, similar to the alteration observed in the Noranda VMS deposits.
