Great Lakes Graphite Inc. announced that preliminary metallurgical testing of graphite samples from the Lochaber Graphite Project in southwestern Québec has demonstrated that a graphite concentrate containing over 57% large flakes (+70 mesh or >180 microns) can be produced from that material. In addition over 45% of the concentrate was classified as jumbo flake (+50 mesh or >300 microns). This represents an exceptional size distribution and the potential for a graphite product that typically attracts a premium price based on the size of the flake.

These results confirm the outcome of previous testing carried out on diamond drill core samples by Rock Tech Lithium Inc. in 2013. This testing has also validated the performance of a new process flow sheet that can be incorporated into future economic and feasibility studies to be commissioned by the company. The Particle-Size Distribution Analysis was done by Process Research ORTECH Inc. ("PRO") of Mississauga, on composite material taken from a bulk sample acquired in August.

The material for this initial sample was visually selected from waste piles at the historical Plumbago Mine site, located on the Lochaber property, with the objective of retrieving high-grade material to be used for the initial metallurgical testing; this material is not intended to be broadly representative of the mineralization that is the target of the ongoing exploration work on the property. The test produced six final concentrates that showed a consistent flake-size distribution and a flake-size distribution of 57.6% greater than 70 mesh; this is the industry-standard premium product.
