Great Lakes Graphite Tests Confirm High Purity of Graphite at Lochaber Property

Toronto, Ontario--(Newsfile Corp. - November 6, 2014) - Great Lakes Graphite Inc. (TSXV: GLK) ("Great Lakes Graphite" or the "Company") is pleased to announce the following update on flotation concentration tests for the Company's Lochaber Graphite property in Quebec, being conducted by Process Research ORTECH ("PRO") at their facilities in Mississauga, Ontario. The tests were completed by PRO on a composite sample of graphite from the Lochaber property, with the objective of developing a flotation concentration flow sheet designed to optimize the preservation of the graphite's crystalline structure and particle sizes, in order to maximize the potential economic value of this high-purity graphite.

PRO has now provided the Company with exceptional flotation concentration optimization results, including:

These results were obtained via conventional flotation only without chemical treatment, i.e. without the use of strong bases (NaOH - caustic roast technique) or acids (H2SO4/HF - acid leach technique).

Concentrate produced by PRO from the mineral beneficiation process was sent to AGAT Laboratories of Mississauga, Ontario for carbon-as-graphite (Cg) analysis, using a LECO furnace and infrared (IR) detector.

CEO Paul Gorman said "These test results confirm that a high-purity concentrate can be easily produced from the graphite at Lochaber. These purity levels taken together with the flake size distribution we recently reported continue to demonstrate the hiqh quality of the mineralization at Lochaber. We continue to build on our business plan of providing battery grade natural flake graphite for the burgeoning battery sector. An NI 43-101-compliant resource estimate is in the advanced stages of preparation and is the final major milestone to complete before commissioning a full Feasibility Study."

Paul Hynek, Director of Technical Services to the Company said, "It is worth noting that we use a modified IR assay method for our graphitic carbon assays. While there are other industry-accepted assay methods that result in the reporting of elevated grades, we are committed to using this method in order to achieve a high level of accuracy. With the method that we incorporate, the sample is pretreated to remove any traces of non-graphitic carbon due to other sources such as organic contaminants and carbonate. It is then heated in a combustion tube to 1350°C in a flowing stream of oxygen where the remaining graphitic carbon is oxidized to form CO₂. The gas stream then passes through an IR detection cell tuned to respond to CO₂. Once the total CO₂ is quantified, the percentage of Cg is calculated.

Historically, and even recently, graphitic carbon was measured using varying forms of an LOI (Loss on Ignition) test where the ore sample was heated to a high enough temperature, usually above 1000°C, to burn off all the carbon and the weight loss was reported as graphite. Of course this was incorrect as chemically combined water, carbonates, organic debris, etc. were all part of this weight loss. This method thus evolved into a two stage LOI, where organic carbon was burned off, chemically combined water and carbonates had a chance to decompose removing those sources of non-graphitic carbon and weight; however, LOI is typically done in air and some carbonates require high temperatures to decompose, in the same range where graphite will burn, so again, there were large sources of error, and typically the error was on the high side. Even the IR method can be misreported if the sample is not pretreated to remove other sources of carbon. Consequently, we have gone to great care to ensure that the labs we use follow a specific protocol, and we have full confidence in the graphitic assays we report."

About Great Lakes Graphite: Great Lakes Graphite Inc. is an industrial minerals company with the mandate to bring graphite projects to production through the acquisition and development of high quality graphite flake properties. Graphite has moved to the forefront of the Industrial Mineral World as a Critical Mineral required for industrial use and as a major component in the development of new technologies particularly with the advancement of battery storage, mobile battery systems and alternative energy infrastructure.

As there are currently no graphite mines producing in North America, Great Lakes Graphite has the ability to become one of the first producers to supply a growing regional customer base that requires high quality natural graphite, where pricing and demand continue to rise.

The Company, through strategic acquisitions and capable management will become a leader in the industrial minerals marketplace. The Company's flagship graphite property is located in Lochaber Township of southwestern Québec. The Company has also entered into option and joint venture agreements with Eloro Resources Inc. on the Summit-Gaber Cobalt property located in the La Grande Greenstone Belt in the Baie James region of Québec. Further information regarding Great Lakes can be found on the Company's website at: www.GreatLakesGraphite.com.
