Focus Graphite Inc. (TSXV:FMS,OTCQX:FCSMF,FWB:FKC) reported pilot plant test results from its Lac Knife project in Quebec, that yielded large flake graphite concentrate (+80 mesh) grading 98.3% Total Carbon.
As quoted in the press release:
The average grade of the coarse size fraction (+ 80 mesh) was 98.3% Total Carbon* (“Ct”) compared with 97.4% Ct in the Phase 2 Locked Cycle Tests** (“LCTs”)
The average grade of the medium size fraction, less than 80 mesh and greater than 150 mesh in size, was 98.2% Ct compared with 97.4% Ct in the Phase 2 LCTs
The average grade of the size fraction greater than 200 mesh was 98.0% Ct compared with 97.2% Ct in the Phase 2 LCTs
The average carbon content of the pilot plant campaign was 96.6% Ct compared to 96.4% Ct reported in the Company’s July 9, 2013 press release on the final results of the Phase II LCTs. It is important to note that these results were achieved despite the fact that the less than 200 mesh fraction was not subjected to another cleaning circuit in the pilot plant run as was done in the LCTs, meaning the carbon content of the overall sample would likely have been even higher.
These results indicate that all three concentrate size fractions may be easier and more cost effective to beneficiate into technology grade graphite due to the high grade carbon content obtained from the pilot plant testing. Higher concentrate grades translates into reduced levels of impurities that have to be removed in the thermal or hydrometallurgical purification processes.
*All carbon analyses were performed by SGS Canada Inc. (“SGS”) and are reported as total carbon (“Ct”). The analytical methods that were used to determine the metallurgical results included total carbon analysis by Leco on the final concentrates. The lower grade tailings products were analyzed by the graphitic carbon (“Cgr”) method to discount the organic carbon and carbonate carbon in the samples.
Focus Graphite Inc. President and CEO, Gary Economo, said:
The pilot plant test results confirm once more the overall quality of our flake graphite resource at Lac Knife; a level of excellence that helps to further de-risk the project. More importantly, the results indicate that all of Lac Knife’s future production holds the potential for purification to premium-priced technology-grade graphite. Lac Knife provides the foundation for our mine-to-market to value-added technology business strategy. We anticipate no impediments to the successful execution of our mining and related corporate objectives.
