RE:Let's organise an audit of ALL the exploration datahi, you can read about the "sugar zone" in this 356 page in what appears to be an ontario government paper. it's been well explored and drilled since about 1969.
hard to believe so much drilling and exploration information is free to view online.
one would think this kind of information would be under lock and key.
