Copper Mountain Mining announces addition to Eva Copper mineral resource

Copper Mountain Mining Corporation has announced drill results from a recently completed exploration programme, metallurgical test work results and a new mineral resource for the Blackard deposit. Blackard is a large stratabound deposit located within the company's Eva Copper Project mining leases, 5 km from the proposed Eva copper processing plant, in Queensland, Australia.

  • Hole BCR910 returned 125 m of 0.57% Cu including 21.5 m of 1.30% Cu.
  • Hole BCR911 returned 78 m of 0.69% Cu including 24 m of 1.17% Cu.
  • Hole BCR917 returned 86 m of 0.59% Cu including 46 m of 0.86% Cu.
  • Hole BCR918 returned 94 m of 0.55% Cu including 44 m of 0.75% Cu.
  • Hole BCR919 returned 72 m of 0.57% Cu including 20 m of 0.68% Cu.

The company also recently completed extensive metallurgical test work that has confirmed economic recoveries at Blackard. Based on these results, flotation recoveries are expected to be 90% for the copper sulfide zone and 63% for the copper zone, both producing saleable concentrates.

The blackard mineral resource consists of a measured and indicated mineral resource of 77 million t grading 0.49% copper containing 836 million lb of copper and an Inferred Mineral Resource of 19 million t grading 0.49% copper containing 206 million lb of copper. The new mineral resource at blackard improves the grade and increases the size of the Eva Copper Project's measured and indicated mineral resource to 228 million t grading 0.42% copper containing 2.1 billion lb of copper.

Gil Clausen, Copper Mountain's President and CEO, commented: "We are extremely encouraged by the potential that exists at Eva Copper. These results lead us to believe that blackard could significantly increase the mill feed and copper production at the Eva Copper Project. We intend to incorporate the information from the blackard mineral resource and metallurgical test work into an updated feasibility study for Eva Copper, the results of which we expect to announce in the 1Q20."
