Jun 04, 2015 (A Wilson) - Copper and nickel values were obtained from two bands of sulphide mineralization in DDH-1. One band was approximately 90 ft. in thickness (385-475 ft.) and the other was approximately 70 ft. thick (525-595 ft.). Assays from these two bands were low; the highest, being 0.175% copper and 0.10% nickel. Sample N14, collected between 442 and 446 ft. returned 0.175% Cu and 0.07% Ni. Sample N17, collected between 470 and 475 ft. assayed 0.140% Cu and 0.07% Ni. Four samples of calcite were assayed for silver but the results were negative. DDH-2 intersected spotty sulphide mineralization at various intervals between 64 and 615 ft. Sample N23 collected between 64 and 66 ft. assayed 0.137% Cu and 0.02% Ni; and a second sample collected between 177.5 and 182.5 ft. assayed 0.125% Cu and 0.02% Ni.
