If you compare the section you reproduced to that of the discovery hole(s) at Romero, it quickly becomes apparent that the reason that none of the drill holes from #20 to #30 produced worthwhile intersections is that they didn't go deep enough.  Just look at how shallow #28 is in relation to the chargeability anomaly.

And copper, which is what is being detected, is closely associated with gold in this system.

No wonder the crews are going back with the deep rigs to give La Escandalosa a second look.   

This may explain why the stock is stronger today in a weak gold market.  I just hope it carries through to tomorrow to save me from the humiliation of recognising Schiff as the superior stock market guru.
