As quoted in the press release:
The Miller graphite showing is described in a report of the Ontario Geological Survey by Lorne Luhta, M.Sc., and is included in the 1989 Report of the Timmins Resident Geologist:
Samples of graphite collected by the Timmins Resident Geologist staff returned analysis of 30.4% and 30.3% carbon. Flake size averages 1 millimetre but some flakes up to 3 millimetre. The sample may have the potential of producing high grade flakes in the minus 300, plus 150 micron fraction.
The underlying geology consists of an east west striking sequence of quartzites and gneisses. Interbedded with the gneisses are graphite rich beds of medium grained granular textured quartzites.
