Mineralization Comments

Oct 27, 2017 (Therese Pettigrew) - Trench A returned assays of 220-2300 ppb Au and 2200 to 39,000 ppm Cu. Trench B returned assays of 950 and 2300 ppb Au and 21,000 to 26,000 ppm Cu. Samples obtained from the trenches varied from andesites to dacites with up to 20% overall mineralization, the bulk of which consists of pyrite, minor pyrrhotite and minor magnetite. In several samples, chalcopyrite and malachite were observed. Some silicification was noted in a few samples. There is a correlation between copper and gold values (AFRI 52F04NW0100).
