Ann: Gold Extraction Results from Ema and Tres Estados, page-122

We'll have assay results in ~4 weeks, but as I explained previously, a 50m RC drillhole provides roughly the same sample size as one of the bulk samples (going on memory). The size of a sample is important because a larger sample size provides a better measure of the average grade. There's no huge difference between a bulk sample and a drillhole apart from the improved grade continuity you get from a drillhole.

I don't need the drilling to understand the potential which is the advantage I have over somebody who needs drillholes. This will be a bulk mining operation rather than a selective mining operation: the bulk surface sampling grades provide sufficient confidence in the grades you might expect when you mine. (http://encyclopedia2.thefreedictionary.com/selective mining)

This is the same reason BBX are pushing ahead with plans to mine: the insane grades from the bulk surface sampling provide sufficient confidence in the grades you might expect when you mine.

How about the platinum group metals and copper silver? That $1.8B doesn't include the PGM and silver credits. Why does it matter anyway? You just don't get it, or you are trolling\downramping. There's a fu*kload of precious metals sitting in the ground, at surface waiting to be mined.
