Mason-Graphite-IncFebruary 22, 2013 (Source: Mason Graphite) Montreal, QC — Mason Graphite Inc. (TSXV: LLG) is pleased to report the completion of metallurgical tests on its Lac Guéret graphite deposit in Quebec that highlight exceptional graphite recovery, excellent concentrate purity and very good particle size distribution.




Result highlights include:

  • Graphite recoveries in excess of 96%
  • Concentrate purity of 96.3% for the +150 mesh cumulative
  • 29% of +80 mesh cumulative, including 16% of +50 mesh

Approximately 1,400 kg of graphite-bearing mineralization were taken from across the different domains of the GC Zone of the Lac Guéret mineral deposit and sent to the independant laboratory, SGS Minerals Services in Lakefield, Ontario for testing. Priority zones were selected and composite samples were prepared for the tests.   A proposed flowsheet was developed and evaluated in two Locked Cycle Tests in order to demonstrate its robustness.


The Company will continue to test these minerals in order to further optimize the flowsheet and will also test other zones of the deposit in order to increase its understanding of the mineralization and validate the flowsheet accordingly.   The graphitic carbon and total carbon content of the head samples were quantified by Leco at 22.0% and 22.7%, respectively. The Carbon Grade was performed by Loss on Ignition (LOI) analysis at 1,000 °C.   “The results from these preliminary metallurgical tests along with the mineral resource estimate published last year confirms to us the robust nature of the Lac Guéret graphite deposit.” said Benoît Gascon, CEO of Mason Graphite. “We are very pleased with the fact that our graphite deposit possesses key elements for mining, processing, and commercial viability; these being high grade, high recovery and flake size. These long-term factors generally contribute materially to the success of a graphite company by delivering a more efficient process and lower production costs.”   Results from these preliminary metallurgical tests will be included in the Preliminary Economic Assessment, scheduled for completion in the coming months.
