Canada Nickel Provides Update on Crawford Project Optimization and Commencement of Pilot Plant Operation
Highlights
-
Testwork demonstrates opportunity for improvements in recovery from the
Crawford East Zone - Locked cycle test delivered a 60% nickel sulphide concentrate – believed to be world's highest nickel grade sulphide concentrate produced – and a total nickel recovery of 47% exceeding the feasibility study model by 9%
- Ten new open circuit variability tests demonstrated nickel recoveries averaging 28% higher than the feasibility study model
- Pilot plant program initiated at SGS Lakefield
Crawford Nickel Sulphide Project East Zone Metallurgical Variability Program
A metallurgical variability program was initiated at the start of 2024 in order to increase confidence in the recovery and concentrate quality estimates and evaluate optimization opportunities for the
Table 1 summarizes the results from the locked cycle test which was completed on a composite of samples taken from the Feasibility Study,
