However, doing the formal, professional studies to turn these estimations into actual publishable numbers costs money and are not presently forthcoming.  So basically, you've got people on the ground at Kimber who know what they've got there, but have to just sit and wait for their opportunity to present the whole thing to the world in the proper format.  

Think about someone who comes into the ER with sudden onset right sided weakness.  You and I know he's had a stroke, but we are not going to call the neurologist until we have a CT Scan to confirm what we know.  We know from experience what is going on and we probably have a good idea what part of the brain is effected, but we need an objective study like a CT before we publish our findings to the world, so to speak.  If we didn't have a CT scanner, could we still call the specialist in and make the report and would it be plausible? Of course, but the standard of care at this time is to get a CT scan, so that's what we do. We are all creatures of protocol to an extent.
