COPPER-GOLD: Carmacks deposit grows for Copper North



YUKON – Copper North Mining has prepared a new 43-101 report for its Carmacks copper-gold deposit 220 km north of Whitehorse. The new numbers show that all categories of resources for both oxide and sulphide portions of the deposit have grown substantially since the maiden resource estimate of 2014.

These are the highlights of the updated resource estimate:

Oxide and transition mineral resources

  • Measured and indicated of 15.7 million tonnes grading 0.94% Cu, 0.74% acid-soluble Cu, 0.379 g/t Au and 3.971 g/t Ag; an increase of 31%.
  • Inferred resources of 900,000 tonnes grading 0.45% Cu, 0.30% acid-soluble Cu, 0.119 g/t Au and 1.900 g/t Ag; a tenfold increase.

Sulphide mineral resources

  • Measured and indicated of 8.1 million tonnes grading 0.68% Cu, 0.178 g/t Au and 2.332 g/t Ag; an increase of 86%.
  • Inferred resource of 8.4 million tonnes grading 0.63% Cu, 0.150 g/t Au and 1.994 g/t Ag; an increase of 108%.

A preliminary economic assessment was completed for the Carmacks project in 2014 (see CMJ Daily Headline News for July 15, 2014). The expansion of the oxide resource will make the project more attractive, according to Copper North president and CEO Dr. Harlan Meade. “Furthermore,” he added, “the expansion of the near surface sulphide mineral resources warrants evaluation for leaching of sulphide mineralization, taking advantage of new advancements in leaching of copper sulphides, such that the copper may be extracted using the same SX-EW technology proposed for oxide mineralization.”
