    Excellent announcement from EGZ. Should get the sp moving in the right direction hopefully.

    EGZ currently up 100% on the announcement.

    Energizer Resources Inc. (TSX: EGZ) (OTCBB: ENZR) (FWB: YE5) (“Energizer” or the “Company”) is pleased to announce that it has achieved greater than 99.9% graphitic carbon from a finished concentrate of the Company’s flagship Molo flake graphite deposit (“the Molo”) in Madagascar.



    This ultra-high purity graphite concentrate of greater than 99.9% C was achieved on a first-pass, single-stage hydrometallurgical purification test at SGS Canada Inc. (“SGS”).The analysis by SGS that achieved this result comprised of an average of five repeat assays on the concentrate conducted over two days. This preliminary test was done to assess the ability to upgrade the Molo graphite to an ultra-pure concentrate.

    Based on these exceptional results, SGS will now begin the development of a comprehensive hydrometallurgical process flow sheet, which will be completed over the next 60 to 90 days and will be conducted in adherence to the technical guidelines of a Full Feasibility Study.

    These studies are part of a series of on-going metallurgical optimization tests targeted at further enhancing both the CAPEX and OPEX numbers presented in the Company’s already robust Preliminary Economic Assessment (PEA) Study from January 2013.

    Craig Scherba, President and COO, stated, “We are delighted to have achieved an ultra-high purity of greater than 99.9% graphitic carbon on the first test. This is highly significant and reconfirms, as demonstrated from the mineralogical results in our completed PEA Study, the exceptional quality of our graphite. As outlined in our previous news releases and PEA Study, the Molo is situated in an extremely rare and unique geological setting which has resulted in our flake graphite being both very high in purity and in quality.”

    The graphite concentrate used in the first pass hydrometallurgical purification testing consisted of a flotation concentrate that was generated in a single cleaner flotation test without optimized conditions. The purification process employed a conventional leach technology and demonstrated exceptional purities.

    Metallurgical Optimization Results and Finalized Process Flow Sheet Imminent

    In June of this year, SGS commenced Phase 1 of the Molo pilot plant process. This comprised of a systematic series of tests to finalize an optimized process flow sheet for the Molo deposit, focusing on minimizing capital and operating expenses of the future mine, while maximizing graphite flake size fractions, concentrate grade, and graphite recovery.

    The Company expects to release the results of Phase 1 to the market within the next 30 days. It is anticipated that these results will have a significant positive impact to the Company’s already robust PEA study, which reported this year an NPV of $421 million (10% discount rate), an IRR of 48%, and a payback of 3 years.
