RE:locationsMag lows are over emphasized to pump up their stock. Zen's deposit is not on a mag low.
Magnetic variation just indicates interesting structural formations. If you look at the original map, CVN's "mag low" is actually a minor peak. Also, BKT's "mag low" is large and has a low gradient, so it's useless information. None of the area plays have interesting features.
Until they do ground testing, it's a waste of money.
