(PresseBox) ( Vancouver, B.C., )
Copper Mountain Mining Corporation (TSX:CMMC | ASX:C6C)  (“Copper Mountain” or the “Company” - - ) is pleased to announce drill results from a recently completed exploration program, metallurgical testwork 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, five kilometres from the proposed Eva Copper processing plant, in Queensland, Australia (See Appendix 1 for Location Map).

Drill hole results highlights:
  • Hole BCR910 returned 125 metres of 0.57% Cu including 5 metres of 1.30% Cu
  • Hole BCR911 returned 78 metres of 0.69% Cu including 24 metres of 1.17% Cu
  • Hole BCR917 returned 86 metres of 0.59% Cu including 46 metres of 0.86% Cu
  • Hole BCR918 returned 94 metres of 0.55% Cu including 44 metres of 0.75% Cu
  • Hole BCR919 returned 72 metres of 0.57% Cu including 20 metres of 0.68% Cu
The Company also recently completed extensive metallurgical testwork that has confirmed economic recoveries at Blackard. Based on these results, flotation recoveries are expected to be 90% for the Copper Sulphide 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 tonnes grading 0.49% copper containing 836 million pounds of copper and an Inferred Mineral Resource of 19 million tonnes grading 0.49% copper containing 206 million pounds 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 tonnes grading 0.42% copper containing 2.1 billion pounds of copper. See Appendix 2 for Eva Copper Project Mineral Resource.

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 testwork into an updated feasibility study for Eva Copper, the results of which we expect to announce in the first quarter of 2020.” 

Mr. Clausen added, “The Blackard deposit is only one of seven historical copper deposits within the Eva Copper Project area that are not included in the current mine plan. We are continuing to drill and advance the other deposits, which we believe could add even more value to the Eva Copper Project.”

October 2019 Mineral Resource Estimate

A summary of Blackard’s October 2019 Mineral Resource estimate is provided below. The new resource estimate is based on approximately 60,600 metres of drilling, which includes drill and assay information up to August 2019.

The mineral resource has been contained within a US$3.50 per pound copper whittle-pit shell.  Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.  Numbers may not add due to rounding, contained metal calculated at 3 significant figures. Cutoff values used for the reporting of each geo-metallurgical zone are based on projected metallurgical recoveries and are 0.23% Cu, 0.20% Cu and 0.17% Cu for the copper, transition and copper sulphide zones, respectively.

The Copper Sulphide Zone consists of primary sulphide material which occurs in carbonate altered sediments and includes bornite, chalcopyrite and hypogene chalcocite copper-sulphide species. Mineralization within the Copper Zone is primarily fine-grain native copper and lesser chalcocite which are hosted within altered metasedimentary schists. The deposit is covered by a shallow weathered cap of ferruginous oxide material that is considered as waste rock.  Given the shallow nature of the cap and that the mineralized material at Blackard is near surface, the Company anticipates a low waste to ore ratio. (See Appendix 3 for 3D Graphic of Conceptual Pit).

The Mineral Resource and metallurgical testwork results on Blackard are currently being incorporated into the Eva Copper mine plan.  The Company plans to complete an updated Eva Copper Mineral Reserve and Mineral Resource estimate and Bankable Feasibility Study in the first quarter of 2020. Ausenco Limited has been retained for the Bankable Feasibility Study.

2019 Drill Results

In 2019, Copper Mountain recently completed an 18-hole drill program (2,695 metres) at the Blackard deposit with the objective of validating the existing deposit model and test for extensions to mineralization. The drill results are included in the October 2019 Mineral Resource.  A summary of significant drill results from this program are provided below. See Appendix 4 for a Drill Hole Location Map, Appendix 5 for cross sections, and Appendix 6 for a Hole Collar Details.
