COPPER NORTH INTERSECTS 34.9 M OF 0.65% COPPER, 0.14 g/t GOLD, AND 2.47 g/t SILVER AT CARMACKS
Copper North Mining Corp. has released results of drilling on the Carmacks oxide Cu-Au-Ag (copper-gold-silver) project, Yukon, Canada. Seven holes were drilled within the zone 2000S as infill and small stepouts to better define the mineralized zone and the boundary between the sulphide and oxide domains. Copper mineralization was intersected in all holes within the zone.
Highlights of the assays included in the extension area:
- CN17-21: 34.9 metres in true width of 0.65 per cent copper, 0.14 gram per tonne gold and 2.47 g/t silver;
-
CN17-15: 21.5 m true width of 0.65 per cent Cu, 0.14 g/t Au and 2.93 g/t Ag;
-
CN17-24: 49.5 m true width of 0.44 per cent Cu, 0.13 g/t Au and 2.14 g/t Ag.

Zone 2000S is located 340 metres south of the proposed open pit and mineralized material crops out on surface. The mineralized zone tapers to the south and the north, but becomes wider with depth. It comprises oxide and sulphide copper mineralization hosted by a steeply east-dipping tabular body of foliated amphibolite up to 50 metres wide. There is a significant oxide cap in zone 2000S that extends to depths of up to 125 metres below surface with abundant malachite, azurite, chrysocolla and tenorite. The chalcopyrite-bornite-sulphide zone is open to depth.
The 2017 drilling has confirmed the high-grade tenor and excellent continuity of the zone. The increase in drill hole density may lead to increases in the level of confidence of parts of the existing mineral resource from inferred to indicated or measured categories.
Dr. Harlan Meade, president and chief executive officer, commented: "The value of zone 2000S is that it represents an opportunity to extend the proposed seven-year mine life. None of the zone is currently included in the mine plan or PEA. The 2017 drilling has focused on expanding and improving the confidence in the copper oxide resources, demonstrating potential and scope for continued operation by exploring the highly prospective ground that surrounds the identified zones on the property."
Results are pending for the remaining 2017 holes in zone 13; assays are expected to be reported shortly.
Maps of the location of zone 2000S and the drill holes are available on the company's website.
Quality assurance/quality control
Quality assurance and quality control procedures include the systematic insertion of duplicate and standard samples into the sample stream. Drill core samples were sawn in half, labelled, placed in sealed bags and were shipped straight to the preparatory laboratory of ALS Minerals in Whitehorse. All geochemical analyses were performed by ALS Minerals in North Vancouver. Total copper assays were performed by four-acid digestion with an atomic absorption spectroscopy finish. Soluble copper assays were carried out by sulphuric acid digestion with an AAS finish. Gold was analyzed by a 30-gram charge fire assay with an AAS finish. Silver was analyzed by four-acid digestion and ICP-AES (inductively coupled plasma atomic emission spectroscopy) finish.
True widths were determined by construction of geological cross-sections along drill fences, interpretation of the bounding surfaces of the mineralized zones, and the width of the mineralized zone was measured perpendicular to the zone boundaries at the centre point of the intersection. The technical information in this news release has been prepared, reviewed and approved by Dr. Meade, a qualified person within the meaning of National Instrument 43-101.
