Energizer Resources Inc. (TSX:EGZ,FWB:YE5,OTCBB:ENZR) announced further positive results from ongoing metallurgical optimization tests from the Molo flake graphite deposit in Madagascar. Latest results from the Phase 1 Molo process optimization testing yielded superior results as compared to the graphite flake size distributions previously reported in the Company’s Preliminary Economic Assessment Study released in February 2013. This is in addition to having achieved an ultra-high purity of greater than 99.9% graphitic carbon on a first-pass purification test.
As quoted in the press release:
The highlights of the open circuit cleaner test results using an optimized cleaning circuit are as follows:
- 47.6% of the concentrate mass is large and jumbo flake graphite (greater than +80 mesh) at a grade of 96.8% C(t);
- 21.7% of the concentrate mass is jumbo flake graphite (greater than +48 mesh) at a grade of 97.4% C(t);
- 23.5% of the concentrate is medium flake graphite (-80 to +150 mesh) at a grade of 95.6%;
- 28.9% of the concentrate is small flake (-150 mesh) at a grade of 95.7% C(t);
Overall, there was a 44% increase in graphite flakes larger than +100 mesh as compared to the PEA study, and the grade improved to 96.3% C(t) from 94.9% C(t);
Exceptional increase in the small flake (-200 mesh) size fraction concentrate grade from 82.1% C(t) to 96.0 % C(t);
The combined concentrate obtained in the test graded 96.2% C(t).
Processing Considerably Simplified
The significant gain in the flake-size distribution and concentrate grades of the Molo graphite deposit was achieved as a result of the SGS test protocol utilizing an optimized circuit that employed only a simple grind and gentle polishing between flotation stages. This process resulted in significantly minimizing graphite flake breakage and is considerably simplified as compared to the process on which the Company’s PEA Study was based.
This open circuit cleaner test will be immediately followed up with a locked cycle flotation test, which simulates the continuous operation of a circuit under laboratory scale conditions.
Substantive Reductions Expected in CAPEX and OPEX
Craig Scherba, President and COO, stated, “These results are very significant because premium prices for graphite are achieved with the highest purity and flake sizes, and Energizer has just achieved marked increases in both. Based on these excellent results, Energizer anticipates that there will be a significant enhancement to the already positive economics of the project presented in our PEA Study.”
