We also have to be prepared for the possibility that the drills miss or miss high grades and that more drilling will be required.  That's the norm.  While many of us are confident that the skarn is rich, even super-rich, that does not mean that an initial round of drilling will prove more than we are close to grades like that.  It's what's in the bottom of the holes that is important.  The richer grades could be deeper. 

We will know soon enough.
