Magnetic survey
it is the dark blue areas on the map that are of the most interest they are the low readings, which often indicate the potential for an ore body These low readings are very similar to what Teck /Highland valley has I am sure Grieg and associates will be all over it. Make of this what you want to ,from my view if HPY has found ore in zone 1 and 2 .What could they find when they drill more into the blue areas.
