All information pertaining to mineral resources herewith presented are historical in nature and while relevant, the information was obtained before the implementation of National Instrument 43-101 reporting standards. No historical estimate should be relied upon until it can be confirmed by the Company.
Dun Raven A is a graphite deposit with historic reserves of 571,532 tons at 4.72% graphite. The graphite grade is known qualified as “good” in the historic. It is easily accessible, 3 and half hours west of Montreal, in the Thorne Township.
The interesting point of this property is that the historic reserves come from drilling over a geophysical (self-potential) anomaly. The reserves are only from the drilled part of the anomaly (200 feet max depth of holes) and there is still left more than 75% of the anomaly to drill. If the mineralized units stay the same as the Dun Raven A deposit, we could expect a 2,286,128 tons deposit at 4.72% graphite. It s told that “Several million tons of ore are indicated” (GM11478) It is also probable that the tonnage or the grade will vary and the overall deposit could be richer. Numerous high grade samples were found at surface.
The only available description from the MRNF of Quebec of the graphite quality is from 1955 (GM11478). A flotation process was able to produce a 77.60% C concentrate. It is said that no problems were expected to produce a 80-85% C concentrate (which was a marketable product). The mesh size of the concentrate was 32.97% +100 mesh. Another test included more grinding and produced 24.43% +100 mesh, 38.38% +200 mesh and 23.57% -200 mesh. The same report tell us that the produced concentrate (76% C) contained a low iron content.
