Copper North Mining Corp. announced the expansion of oxide copper-gold-silver mineral resources at the Carmacks Project, Yukon Territory. The mineral resource expansion is in the southern extension of the Carmacks mineral deposit, in Zones 2000S, 13, and 12, on the basis of the step-out and infill drilling program conducted in September and October 2017 and the recently completed updated mineral resource estimate ("Updated Mineral Resource"). The Updated Mineral Resource has been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") by Independent Qualified Person, Dr. Gilles Arseneau, P.Geo. Highlights of the Updated Mineral Resource in Zones 2000S, 13, and 12: step-out and infill drilling in fall 2017 was successful in confirming continuity of the mineral zones and grades of the oxide and sulphide mineralization in the southern extension of the Carmacks mineral deposit; updated Oxide Measured and Indicated Mineral Resource increased to approximately 4,300,000 tonnes - grading 0.47% copper, 0.13 g/t gold and 1.92 g/t silver; the new Oxide Measured and Indicated Mineral Resource increased 40% over the 2016 Mineral Resource, primarily from lateral expansion of the oxide mineralized zone - upgrading of the already minor inferred resource category was a small contributor; the new Oxide Measured and Indicated Mineral Resource in Zones 2000S, 13, and 12 has the potential to provide an additional 2.4 years of mill feed at the planned processing rate of 1.775 million tonnes per year, subject to economic confirmation by future mine development planning; and the Updated Sulphide Measured and Indicated Mineral Resource totaled 4,416,000 tonnes grading 0.62% copper, 0.13 g/t gold and 2.3 g/t silver, and an equal tonnage of mineral resource in Inferred category.
