Maronan Metals Limited (ASX:MMA) Announces Outstanding Metallurgy Results
Metallurgical Optimisation Results
Maronan Metals Limited achieved high-grade silver-lead concentrates, with flotation testwork producing concentrates grading over 74% lead and over 2900 g/t silver. Lead and silver recoveries reached up to 95% and 91%, respectively. These results were obtained using a primary grind of 100 µm and regrind and cleaning at 23 µm on ore with a head grade of 4.4% lead and 181 g/t silver. The flotation reagents used were common industry standards, and concentrate leach tests demonstrated the ability to reduce fluorine content by over 50%.
Future Outlook
Further metallurgical samples are being collected for ongoing metallurgical characterisation and detailed process design, aiming to better define mine production parameters and de-risk the project.
Executive Comments
Managing Director Richard Carlton stated, “To be able to return such strong recovery and concentrate grade results is an excellent outcome. This result is a further confidence builder in our program to better define the mine production parameters and de-risk the Project. Carbonate hosted silver-lead ore would form a significant proportion of any early production profile.”
