I think it is very relevant that BGM had hired Snowden back this spring to do the final work on the reports by PG and Mintek.  I would think it would be very hard for anyone to question their findings.  With 2100 holes to work with and many very current I would hope they have enough data to complete a resource report and that it turns out well.  Here is an article written by one of their founders and gives us some insight into their wealth of experience and some insight into their thought process on resource estimation even with some case studies.
