Great Lakes Graphite Achieves Milestone in Preparation For Battery Markets

Thermal Purification Tests Resulted in Graphite Purity up to 99.997%


/EINPresswire.com/ -- TORONTO, ONTARIO -- (Marketwired) -- 08/15/16 -- Great Lakes Graphite Inc. ("GLK" or the "Company") (TSX VENTURE: GLK) (OTC PINK: GLKIF) (FRANKFURT: 8GL) announces today the results of thermal upgrading of graphite feedstock material being sourced for the Matheson Micronization Facility. The thermal purification was conducted by TevTech LLC, a leading commercial manufacturer of industrial furnace equipment on graphite feedstock material that was first micronized at a pilot plant facility. A series of tests designed to measure the effect of different operating parameters with the objective of obtaining maximum purity were performed on micronized graphite samples. The samples were then thermally upgraded with the best result returning 99.997% purity.

Highlights:


--  Assays confirm that GLK's micronized flake graphite products can be
    upgraded to 99.99%+ purity, with a thermal purification method
--  High purity graphite is required to satisfy requirements of high value
    markets
--  Testing provides data for preliminary estimates of CAPEX and OPEX
    requirements for a commercial-scale solution, in addition to performance
    data

CEO Paul Gorman said, "GLK is working with partners who are each well-established industry experts, with the objective of building intellectual capital regarding the purification of our micronized graphite products. While this work is ongoing, initial results have demonstrated that our graphite products can be upgraded to 99% purity and above, using both chemical and thermal methods."

Thermal Purification

Great Lakes Graphite is working with TevTech LLC, a private company based in Billerica, Massachusetts that is a leading commercial manufacturer of high-temperature industrial furnaces. These furnaces are capable of operating at the temperatures that are required to purity graphite to very high levels.

Special purpose graphite crucibles were loaded with samples of micronized flake graphite which were then delivered to the manufacturer's facility. A series of tests were conducted to provide performance data at different temperature levels and other techniques that were used to maximize purity.

Jim MacDonald, Managing Partner at TevTech LLC said, "We are impressed with the effort and focus of the GLK team to have the ability to explore alternative processes to successfully develop products to meet widely varying customer requirements, especially during a commissioning phase of a production facility. Our partnering efforts have yielded exceptional results by altering existing technology used in other mature high tech applications to design products with custom tailored, superior properties".

Purification Assay and Analysis Results

Samples from the tests were submitted Evans Analytical Group at their facilities in Liverpool, New York for assay by Glow Discharge Mass Spectrometry ("GDMS"). The samples included: flake graphite concentrate, purified flake graphite concentrate and thermally purified micronized flake graphite.

Ultra-trace amounts of selected elemental contaminants detected in the purified micronized flake graphite sample are shown in parts per million (PPM) in the table below. A copy of the assay certificate for all 73 elements that were analyzed by GDMS analysis can be found in the "GDMS report for MG-4599" on the Product Literature page at the corporate website:

CEO Paul Gorman said, "These purification test results are significant in two ways. First, we have demonstrated that the material we will be micronizing at the Matheson Micronization Facility can be upgraded to the very high purity levels required by the highest value applications. Our partners are helping to lay the foundation for further efforts that will generate more detailed CAPEX and OPEX costs."

Vice President of Sales Alan Devaney said "These tests confirm that the graphite we are sourcing can be upgraded using various methods to very high levels of purity. Applications requiring high purity graphite are typically very sensitive to particular types of impurities like vanadium, even in trace amounts. This testing confirms that we have the right product to go after the high value markets and is also providing material for samples. Qualification for the battery market, for example, routinely involves testing that can require up to 18 months. While our near term sales efforts are focused on markets that are more readily accessible, we are also actively working with and getting our product into the hands of battery manufacturers and others who require high purity graphite."
