Great Lakes Graphite Inc. ("GLK" or the "Company") (TSX-V:GLK) (OTC-PINK:GLKIF) (FWB:8GL) announces today that the Company has received a large initial purchase order for 50,000 pounds of micronized natural flake graphite from a new customer. The customer, who is unnamed for reasons of commercial confidentiality, is a Fortune 500 corporation.

Highlights

-- Great Lakes Graphite has successfully completed rigorous product qualification testing and vendor approval process with a new customer.

-- The customer has ordered an initial 50,000 pounds of material for delivery by mid-December and has indicated a requirement for 280,000 pounds in 2018 for delivery in monthly installments.

-- The customer anticipates that their demand for this product will increase steadily over a three year period, requiring 1,500 tons per year by 2020.

-- Product qualification work by GLK continues to expand the sales pipeline in drilling and battery markets.

Great Lakes Graphite was recently notified of their approval as a vendor by a new customer and that the Company has been established in their purchasing system, the final steps required before purchase orders can be generated. Sr. VP of Sales Michael Coscia said, "Obtaining vendor approval and large volume purchase orders are the result of lengthy and often complex product qualification processes. In this case, there were twenty-six months between first contact and final qualification."

The customer intends to perform final field trials over the balance of the year, which will require 50,000 pounds (or 25 tons) of material in the fourth quarter of this year. Deliveries for the first full year requirement of 280,000 pounds are expected to begin in the first quarter of 2018 and continue through the year. Volume requirements are expected to increase to between 500 and 1000 tons for the second year and then 1500 tons for the third year.

Great Lakes Graphite CEO Paul Gorman added, "Diligent effort over the past few years has resulted in these initial successes. Consistently high quality and the ability to deliver product, source from Brazil, to a customer's specifications are the keys. We have built a robust supply chain that embraces and promotes environmental sustainability and corporate social responsibility."

Product Qualification Work Continues to Expand the Sales Pipeline in Drilling and Battery Markets

In addition to the customer that is the subject of this announcement, the company recently qualified graphite products with two other prospects in the oilfield drilling services and lubricants industries.

A fourth prospective customer, one of the largest manufacturers of lead-acid batteries in North America, has indicated that their two-and-a-half year product qualification effort is expected to conclude at the end of the year. All results to date have met or exceeded the requirements of this prospective customer for this application.
