Maronan Metals (ASX:MMA) said metallurgical optimization test work on the carbonate-hosted silver-lead ore type from the Maronan lead-silver and copper-gold project in Queensland resulted in the production of very high-grade silver-lead concentrates, according to a Tuesday Australian bourse filing.
Flotation test work produced concentrates grading at over 74% for lead and more than 2,900 grams-per-tonne grade of silver, with recoveries for lead and silver up to 95% and 91%, respectively.
While there were minor elevated levels of antimony and fluorine in the final clearer concentrate, concentrate leach test work has shown that fluorine content can be reduced by more than 50%.
It is collecting further metallurgical samples for ongoing metallurgical characterization and detailed process design.
