I will take the liberty of reposting one of George J's earlier posts so we can compare what Winspear has announced with other findings;I think we can agree that by comparison WSP's announcement looks mighty good!

What is evident in these numbers is the wide range of parameters that exist and varying combinations of gem quality., grade and tonnage all play interchanging roles in determining potential value. What is little known about the above deposits., is the percentages of large stone which comprise the bulk of the value of each of those deposits. Some interesting numbers., non the less.
