This is all excellent and very exciting news. Short of actual assay reports this is very good news. It is very good that they are deep and appear to be going deeper. As previously related, based on ZTEM- JB has noted that the main ore body could be as deep as 5000 feet. I understand that is very deep for extraction- but if the concentration is as expected then I assume even such deep deposits would be worth mining. As for the shallower skarn associated deposits cited by VP- they may still be intersected. 
All good- in fact- Great!
