Great Lakes Graphite Inc. announced that it has entered into a 5 year supply agreement with DNI Metals Inc. for the procurement of natural flake graphite concentrate. Under the terms of the agreement, GLK will have the ability to purchase up to 34,000 tones of material from DNI, which will be sent to the Matheson Micronization Facility for the production of micronized flake graphite. To ensure final product consistency and quality, all of the concentrate will be sourced from a mill that has met the testing requirements performed by the company over the last 6 months.
