Flake size for the Bissett Creek samples was 77% +80 mesh (deemed large) and 50% +50 mesh (extra large). The average graphitic carbon (Cg) content was 97.5%, very high for a flotation concentrate. After attritioning and standard acid purification, the grade was 99.0%.
ProGraphite also suggested that Bissett Creek graphite may have particular application in the manufacture of bipolar plates for hydrogen fuel cells.
Northern Graphite has completed a full feasibility study and received the major mining permit. The next step is a construction decision.
