Reasons I like TMX and think it may be worth more, page-9

No they are not, far from it and it wouldn’t stand up as evidence in court, and nothing much shows up on GW. Two months ago I was sitting in front of a Geos laptop and he showed me Airmag data from Cerro Morro, in particular a 700,000 Au oz vein he discovered and named after his daughter. He said see it? Can you see it? I said no Mate, I couldn’t see it and you would think 700,000oz would stand out, he ended up pointing to along narrow area between the highly coloured bits not on them.
I guess whenever someone puts Airmag data up I think of that and unless your trained in it’s interpretation it remains an interesting picture for discussion amongst us lawyers and ex farmers, but even for the trained geos it’s some form of indicator that an anomaly is there not necessarily PMs or BMs.
