Metallurgical Testing Confirms High Value Concentrates

Feb 22, 2021
February 22, 2021 – Northern Graphite Corporation (NGC:TSX-V, NGPHF:OTCQB) (the “Company” or “Northern”) is pleased to announce that ongoing metallurgical testing continues to confirm the high percentage of valuable, large flake concentrates that will be produced from its Bissett Creek deposit. Recent tests have averaged 22 per cent +32 mesh (XXL) flake and 46 per cent +48 mesh (XL) flake. Cumulatively, 95 per cent of concentrates produced are expected to be greater than 80 mesh which is the cut-off for large flake1
 
All figures are believed to be the highest large flake yields reported from any worldwide graphite project.
 
Few deposits contain any appreciable amounts of XXL flake material. As a result, the market is under supplied and prices exceed US$2,000/tonne. Currently, XL flake graphite sells for approximately US$1,750/t, large flake for US$1,020/t and small flake for only US$600/tonne2
 
The Company expects that its concentrates will sell for a weighted average price of US$1,600/t in the current market. Most graphite deposits contain high percentages of smaller flake sizes and will realize US$1,000/t or less. Larger flake sizes are used in high value, high margin industrial markets including the manufacture of bipolar plates for fuel cells and vanadium redox batteries as well as primary batteries, thermal management in consumer electronics, fire retardants, insulation products, ceramics, lubricants and many other applications.
 
A recent independent study estimated that the Bissett Creek deposit will have the highest operating margin of any current or proposed graphite mine. This is due to its exceptional flake size distribution, simple metallurgy and very favorable location with ready access to equipment, supplies, labor and markets.
 
Gregory Bowes CEO commented that: “Northern already has a project with good economics based on current prices and a realistic production level relative to the current size of the market. The economics for most projects are being presented using prices well above the current market and/or with high production rates that would actually cause market prices to decline.” He added that: “Multiple new graphite mines will ultimately be required to satisfy the projected growth in LiB/EV markets and to provide secure, transparent, ethical sources of supply that are not dominated by the Chinese. Increasing demand is expected to lead to the higher prices required to stimulate such development.”
 
SGS Lakefield previously carried out metallurgical testing to validate a simplified flow sheet with lower capital and operating costs for the Bissett Creek Project. Testing confirmed that the new flow sheet could produce high purity concentrates albeit with a small decline in recoveries and large flake yields compared to the original Feasibility Study.
 
While the net effect was positive in terms of the estimated concentrate sales price, the lower large flake yield was unexplained. Possibilities included the effect of sample aging and a loss of material during multiple stages of core splitting, sampling and handling. According, the Company recently drilled four twin/test holes and subjected both the new core and the adjacent old core to flotation testing, the only accurate method of determining flake size distribution in a sample.
 
To date, the twin holes have returned high and consistent +32 mesh yields that are as good or better than testing completed during the feasibility study. The XXL flake yield from fresh, whole core samples was also approximately 10 per cent higher than from comparable older, weathered samples. This indicates that flake loss likely does occur during sampling and handling and that the composites used in the previous testing may have been compromised in some way.

About Northern Graphite
 
Northern Graphite is a mineral development and technology company focussed on developing its Bissett Creek graphite deposit and upgrading mine concentrates into high value components used in lithium-ion batteries, electric vehicles, fuel cells, graphene and other advanced technologies. An independent study estimates that Bissett Creek will have the highest margin of any existing or proposed graphite deposit due to its very favorable location, simple metallurgy and the high quality of its concentrates which provides the Company with a competitive advantage in manufacturing products that enable the green economy.
Bissett Creek is an advanced stage project with a full Feasibility Study and its major mining permit which puts the Company in position to make a construction decision, subject to financing. The Project is located in the southern part of Canada between the cities of North Bay and Ottawa and close to the Trans-Canada highway providing ready access to labour, supplies, equipment, natural gas and markets.
