Great Lakes Graphite and AshlanD PartenershipGreat Lakes Graphite and Ashland Advanced Materials Partner on Purification TORONTO, ONTARIO--(Marketwired - March 22, 2017) - Great Lakes Graphite Inc. ("GLK" or the "Company")(TSX VENTURE:GLK)(OTC PINK:GLKIF)(FRANKFURT:8GL) today announces that the Company and Ashland Advanced Materials, LLC ("AAM" or "Ashland") have formed a partnership to work together to develop the capability for industrial scale purification of micronized graphite. Access to large volume purification capabilities will create a strong competitive advantage for Great Lakes Graphite as it continues preparations to join the energy storage and lithium-ion battery market supply chains. Highlights Great Lakes Graphite is partnering Ashland Advanced Materials, a leading provider of high purity graphitized carbon products. Baseline purification cost data and material for customer sampling have been generated. Niagara facility is optimally located to benefit from well established battery-related initiatives in upstate New York, including the recently opened Battery Commercialization Center. Great Lakes Graphite has established a partnership with Ashland Advanced Materials, LLC, a privately-owned, leading provider of graphitized carbon products, headquartered in Niagara Falls, New York. The partnership is focused on high volume purification of micronized flake graphite. Towards this end, Great Lakes Graphite and Ashland have executed a Memorandum of Understanding that establishes a framework for now moving towards a definitive agreement that will formalize the terms of the partnership. Senior Vice President of Sales Mike Coscia said, "We are extremely fortunate to have a partner with the advanced, industrial-scale graphite purification capabilities that Ashland offers.

The initial purification work we have done together is providing baseline cost data and also high purity micronized graphite material for our customer sampling program." The partnership will seek to leverage Ashland's Niagara location by connecting to ongoing economic development initiatives that are well-established in the region. In January 2017, New York Governor Andrew Cuomo announced Buffalo Billion Part 2, a continuation of a major state commitment to economic development in the Buffalo-Niagara area. Among other things, that initiative is targeting funding for strategic advanced manufacturing projects. New York State has made a significant commitment to becoming a global leader in battery technology through investments in the New York Battery and Energy Storage Technology Consortium (NY-BEST) headquartered in Albany, New York (https://www.ny-best.org/) and the Battery Commercialization Center that recently opened in the Eastman Business Park in Rochester, New York (https://tinyurl.com/hke7vk2). Matt Reineke, President of Ashland Advanced Materials, LLC, said, "We are excited about working with Great Lakes Graphite on graphite purification. We have gotten to know the team over the past year of working together and believe that there is a significant opportunity for high purity micronized graphite for a number of rapidly-growing markets.
