Canada Nickel Achieves Initial Metallurgical Success at Mann Northwest Property
Highlights
-
First two metallurgical tests at Mann deliver strong recovery and concentrate quality:
- Overall nickel recoveries of 58% and 59%.
- Nickel and magnetite concentrate grades in line with expectations.
Table 1 summarizes the recovery results of the first two open circuit tests from the Mann Northwest property on samples with head grades of 0.29% and 0.30% nickel. The samples were tested at a third-party lab to evaluate the metallurgical potential of the property. Both samples delivered strong recovery performance, with total nickel recoveries of 58% and 59% and iron recoveries of 44% and 48%. Cobalt recoveries were 15% and 28% and chromium recoveries were 10% in both tests. More than half of the recovered nickel was recovered to nickel concentrates with an average grade greater than 38% nickel. Iron concentrate grades averaged 58% and 62% iron in the two tests. The Company will follow a similar metallurgical program path as it did with Crawford and begin a variability open circuit testing program to confirm operating parameters and performance and then begin locked cycle testing to confirm metallurgical performance and concentrate grades and recovery to be used in future engineering studies.

The samples were selected as higher grade, well-serpentinized dunite samples and confirmed the potential to transfer the Crawford metallurgical process to the Mann ultramafic nickel mineralization. The standard test procedure from the Crawford Feasibility Variability Program was used including grind sizes, reagent dosing strategies and flowsheet layout.
Figure 1 shows the plan view of the Mann properties with the "X" markers indicating where the samples were taken from. Sample 1 was taken from drill hole MAN23-03 from 200 to 273 meters and Sample 2 was taken from MAN23-02 from 112 to 164 meters.
