I have the same suspecion about the north end of eagle 1....
Holding NOT/ PRB and FNC..... seams like NOT is a little too quick to terminate extension of the deposit to the north and south..... If one was trying to maximize the initial deposit wouldn't the extension North and south be of prime importance..... seams the miss to the south was intensional.... and the same suspicion to the north was my concern some time ago......
I would only call a fence of holes with deep vertical close spacing over several hundred meters as confirmation of termination of the Eagle 1 lens.
The PRB recent MMI results ..... and most recent update of Out crop and results from ground loop confirm this in PRB's case.
FNC and PRB will have to drill to confirm their targets have merrit on their own and the sooner the better.
JMHO
