Vancouver, British Columbia--(Newsfile Corp. - October 31, 2017) - Copper North Mining Corp. (TSXV: COL) ("Copper North" or the "Company") announces progress of drilling on the Carmacks oxide Cu-Au-Ag project, Yukon, Canada. Approximately 4,000 metres have been drilled to date, in 32 holes, as part of an ongoing step-out and definition drill program. The drilling has mainly focused on two mineralized zones: Zone 2000S and Zone 13, last drilled in 2015. Oxide copper mineralization, native copper, and sulphide copper mineralization have been observed in drill cores from Zone 13 and Zone 2000S; assays are pending. The objective of this drill program was to upgrade our Inferred oxide copper mineral resources into the Measured or Indicated resource category, and therefore the potential for a longer mine life. The drill results to date supports this potential mine life increase.
Zone 13
Oxide copper mineralization was noted in all nine in-fill holes drilled within Zone 13 to date. This confirms the continuity and extent of oxide copper mineralization present within the existing Mineral Resource. The supergene copper minerals azurite, malachite, and tenorite transition to chalcopyrite-bornite mineralization having depths up to 100 metres below surface. Native copper has been observed at the transition from copper oxide to copper sulphide mineralization.
Zone 2000S
Infill drilling has targeted the oxide zone in the southern half of Zone 2000S. The completion of seven drill holes has successfully confirmed the presence of visible malachite, azurite, and tenorite in the zone up to approximately 100 metres vertically from surface. The additional drilling has provided better constraints on the location of the oxide to sulphide interface, confirming the presence of copper oxide mineralization at depth.
President and CEO Dr. Harlan Meade commented: "the additional drilling in Zones 13 and 2000S has increased the drill hole density with the objective of upgrading part of the Inferred resources to the Measured and Indicated categories. Step-out drilling is underway to test the presence of oxide and upper part of sulphide mineralization in the gap between Zones 13 and 12. Initial observations of copper oxide mineralization from the first step-out holes suggest that we may expect an increase in Mineral Resources and the potential for an extended mine life.".
Wildcat Holes
Holes CN17-04 to CN17-11, CN17-16, and CN17-17 were drilled away from known mineral zones considered as wildcat holes. No significant mineralization was intersected in these drill holes.
Engineering and Environmental Studies
As part of the fall exploration program, groundwater and geotechnical field studies were completed in the proposed dry-stacked tailings area by Golder Associates. The field study results will support continued engineering design for the tailings area and updating of the site water balance and water quality models in support of future environmental assessment and permitting. Doug Ramsey, VP Sustainability and Environmental Affairs, commented "Completion of these field studies puts us on track for entering the Yukon environmental assessment process in 2018 to maintain our planned 3-year development schedule".
