Northern Graphite – Purity Matters
Purity matters in graphite because a higher carbon content and larger mesh size usually translate to higher value. No two graphite deposits are the same. A review of Northern Graphite’s press releases shows that it has spent considerable effort educating the markets about the special purity of its Bissett Creek graphite deposit.
Northern Graphite’s latest substantive press release (not including the MD&A and financials) from March 2, 2015 looked at the independent testing results carried out on that graphite by NGS Naturgraphit GmbH.

Naturgraphit tested large flake and combined XXL / XL flake concentrates for volatile matter, moisture content, ash content and expansion volume, and also carried out microscopic examination of each flake size for degree of crystallization and for the presence of impurities.
Among Naturgraphit’s findings of fact were that flake graphite concentrates from Bissett Creek met or exceeded the quality requirements for major end users of graphite; the graphite flakes were almost free of discoloration and impurities; there was very little calcium carbonate, iron sulphides or volatile matter; and, the graphite contained a very low heavy metals content.
From these and other facts, Naturgraphit concluded that Northern Graphite could achieve high purity values from Bissett Creek with an inexpensive process, and that the samples from Bissett Creek are suitable for refractory applications.
These conclusions are important as they support Northern Graphite’s business strategy to feed demand growth for graphite as a supply critical mineral, while incurring the minimal capital costs possible.
That press release followed the Jan 22/15 release addressing the concentrates reaching nuclear grade purity, and the Aug 12/14 release confirming a high spherical graphite yield. These releases, together with Northern Graphite’s other disclosures, display the unique characteristics of Bissett Creek.
Bissett Creek is between Ottawa and North Bay, Ontario, about 15 km off the TransCanada Highway, giving it good road access. With a Feasibility Study calling for a 28 year mine life and an indicative term sheet with Caterpillar for equipment financing, Northern Graphite is on its way to turning Naturgraphit’s report into reality.
