Canada Nickel Company Inc. (Canada Nickel) announced further results of metallurgical testing at its Crawford Nickel Sulphide Project that continue to demonstrate significant improvements in metal recoveries relative to the Preliminary Economic Assessment (PEA).
This open circuit test (OCT) was completed at COREM on a heazlewoodite dominant sample with a head grade of 0.22% nickel, 6.8% iron and a sulfur to nickel ratio of 0.36. The latest metallurgical test work results are from a sample taken from the South Low-Grade region of the Crawford Main Zone. The achievement of 61% nickel recovery from a low-grade sample is consistent with results from other samples. The Company is commencing the first phase of metallurgical variability testing for the feasibility study to better understand metallurgical performance from samples taken throughout the Crawford resource.
In addition to the excellent nickel recovery, the iron and chromium recoveries were also 15 and 18 percentage points higher than what was modeled in the PEA respectively.
