Copper North Mining Corp. ("Copper North" or the "Company") (TSX VENTURE: COL) announces the results of drilling on the Thor property in northwest British Columbia. Drill hole TH16-01, in the Thor East target area, intersected porphyry copper-gold mineralization. Drill holes TH16-02 and TH16-03 were drilled in the Thor West target area and failed to intercept favorable geology (see September 9, 2016 news release).
Drill hole TH16-01 intercepted an intensely fractured and veined granodiorite that contains copper mineralization, from a depth of 11.65 m to 119.25 m. Traces of copper mineralization are present below 119.25 m until the end of the hole at 169.16 m. The granodiorite is in contact to the east with the Takla Group volcanic rocks that are also extensively fractured and veined. The transition from stronger mineralization and quartz-veining at the top of the hole to weaker copper mineralization and phyllic alteration at depth suggests that drill hole TH16-01 may flank a mineralized porphyry centre.
History and Target Areas
Exploration in the 1960s to 1990s discovered porphyry copper-gold type mineralization on the Thor property. The Thor Property covers approximately 20,000 hectares including the historic Thor, Marmot, Thorne and Goldvale mineralized areas. The mineral prospects follow a 20 km long mineralized zone within the central part of the porphyry copper-gold trend, from Kemess North in the north northwest to Kliyul in the south southwest, a distance of 75 kilometres.
Drilling and geological survey work this past summer indicates that drilling is warranted in follow-up of drill hole TH16-01 in the Thor East target area. The next steps for exploration include ground surveys in the Thor East area, and evaluating multiple geochemical targets and alteration zones. Field work has outlined multiple targets over a 4 by 6 kilometre area to the southeast of the TH16-01 discovery area (see Appendix 1).
Dr. Harlan Meade, President and CEO, states that, "The large area of porphyry alteration and gossan zones, remain an attractive exploration target. The Thor Project provides Copper North an opportunity to explore for porphyry copper-gold type mineralization in the slopes and valleys 20 km to the south of Kemess South mine and mill complex in North Central BC."
Quality assurance and quality control procedures include the systematic insertion of duplicate and standard samples in to the sample stream. Drill core samples were sawn in half, labelled, placed in sealed bags and were shipped directly to the laboratory of SGS Mineral Services in Burnaby for geochemical analyses. Copper was assayed by four-acid digestion with an ICP-AES finish. Gold was analyzed by a 30 g charge fire assay with an AAS finish.
