Certified Bench-Scale Flotation Testing by SGS Geosol

Preliminary metallurgical characterization has been conducted for the Macarani Graphite Project. In September 2024, SGS Geosol received ten graphite mineralization samples collected from the Project, totaling approximately 256.1 kg.

The samples were blended to produce a composite sample for technological characterization and preliminary bench-scale flotation testing. Following preparation, the composite material was homogenized and divided into 1 kg subsamples for laboratory testwork.

The open-circuit flotation process, utilizing a scrubber and seven cleaner stages, yielded the following preliminary bench-scale results:

Feed Grade: 5.20% Cg
Concentrate Grade: 81.5% Cg
Metallurgical Recovery: 72.5%
Mass Recovery: 4.62%
