TORONTO, Nov. 15, 2022 /PRNewswire/ - Canada Nickel Company Inc. ("Canada Nickel" or the "Company") (TSXV: CNC) (OTCQX: CNIKF) today announced the results from initial phases of pilot plant testing on 34 tonnes of material from the Company's Crawford Nickel Project with the major focus on testing an updated magnetite recovery circuit and generation of both nickel and magnetite concentrates for further downstream testing. While the Crawford Nickel Project is primarily a nickel development project, it can produce value-generating by-products including cobalt, palladium, and platinum contained in the nickel concentrates, and iron and chromium contained in the magnetite concentrate expected to be produced from Crawford.
Mark Selby, Chair and CEO of Canada Nickel commented, "Our updated magnetite flowsheet has delivered outstanding improvements in both product quality and iron and chromium recoveries which we believe could add substantial additional value to the project. The pilot plant performance to date has exceeded our expectations in terms of operability and production and we look forward to the completion of the work on the final phase of nickel concentrate production."
Selby continued "Today's work highlights the potential of this project to be an important producer of multiple critical minerals – nickel, cobalt, palladium, platinum and the only North American producer of chromium. We are already in multiple discussions with leading North American and European stainless and ferroalloy producers on downstream processing partnerships for processing this material who are excited by the structural advantages of our project location with its substantial infrastructure, regional history of downstream processing, access to low carbon electricity, and most importantly, the potential to capture carbon emissions using Crawford's In Process Tailings ("IPT") Carbonation Process which would facilitate zero carbon production of downstream steel and ferroalloy products"
Pilot Plant Overview
In October 2022, Canada Nickel completed the first phase of a 34-tonne pilot demonstration of the Crawford Metallurgical Flowsheet at SGS Canada Inc. in Lakefield, Ontario. The pilot plant was initiated to evaluate the performance of the flowsheet with continuous feed as well as to generate concentrate for downstream flowsheet development work and product marketing purposes. The initial phases of testing, which is reported in this release, included the rougher level flotation stages and the magnetic recovery circuit, each of which exceeded expectations in terms of operability and production. The remaining phase of testing, which is scheduled to be completed in November 2022, will involve the final cleaning stages of the intermediate flotation concentrate. This release reports on the results achieved from the magnetic recovery circuit which delivered improved iron and chromium recoveries and improved concentrate grades relative to what was modelled in Crawford's Preliminary Economic Analysis ("PEA").
For the pilot exercise, five composites, ranging in size from 4 to 7 tonnes, were built from 53 samples of large diameter drill core from 19 holes to represent different lithologies and mineralization styles from across the deposit with a focus on the expected project payback period to be used in the feasibility study. Table 1 summarizes the feed characteristics of each of the composites, the achieved iron, chromium and nickel recoveries into the magnetic concentrate, as well as the modelled recoveries that were used in the PEA with the following comments:
- The pilot plant is delivering improved iron and chromium recoveries and at an improved concentrate grade relative to the PEA.
- Composites tested were from both the Main and East zones across both dunite and peridotite lithologies, with nickel head grades in the range of 0.20 –
0.33% and sulphur head grades of 0.07 –0.49% . - Four out of five of the composites tested achieved iron recoveries that were higher than what was modelled in the PEA, with an average improvement of
18% in recovery. - All five of the composites achieved or exceeded the chromium recoveries that were assumed in the PEA, with an average recovery of
31% that represents a15% improvement in recovery. - Nickel recovery to the magnetic concentrate was in the range of 3 –
8% with an average of5% . As expected, samples with a lower sulfur head grade, that contain the magnetic mineral awaruite (Ni2.5Fe) showed higher recoveries of nickel to the magnetic concentrate.
