Cassini Resources Completes Positive Metallurgical Testwork
THE DRILL SERGEANT: Cassini Resources (ASX: CZI) has completed a detailed metallurgical testwork program as part of Further Scoping Study (FSS) activities at the company’s West Musgrave project (WMP), located in Western Australia.
Cassini Resources indicated the program of work represents the first stage of the Earn-in/JV Agreement with OZ Minerals (ASX: OZL).
The company said the testwork program has confirmed the successful production of separate, saleable nickel and copper concentrates from all mineralised domains, including the weathered ore-domains.
The program returned nickel concentrate grades of 10 to 12 per cent achievable at 60 to 70 per cent recovery and copper concentrate grades of 21 to 25 per cent achievable at 78 to 80 per cent recovery.
This current program has increased Cassini’s level of understanding and confidence in the metallurgical performances across a complete range of mineralisation types within the Nebo-Babel deposits.
It focused on lower head grade samples across the primary and weathered ore domains, some of which were not previously tested. No oxide material is being considered for treatment.
A large component of the testwork included optimisation of the process flow sheet, and testing of alternative reagent regimes, all of which were aimed at further improving nickel and copper recoveries and concentrate grades.
“At the commencement of the FSS, there were two key technical outcomes we targeted to ensure the viability of the project,” Cassini Resources managing director Richard Bevan said in the company’s announcement to the Australian Securities Exchange.
“They were the identification of a near-by groundwater source, and confirmation that the metallurgy results we had previously achieved could be reproduced at lower nickel and copper grades and throughout the weathered zones.
“To have achieved positive outcomes in both of these is a fantastic result by the team and a significant step forward for the project.
“This metallurgical program confirms that there are no fatal flaws in the mineralogy and that the processing flowsheet will be comparable to other nickel and copper sulphide projects globally.
“We have now done a significant amount of metallurgical work for a scoping level study and are confident that we will continue to improve these outcomes as we progress through the next study phases.”
