Sorry for not being a complete Fan Boy!
Not sure what the "sour" is about as most of my posts have either been on providing general diamond industry info or specific BDM/Ellendale.
I actually support BDM's approach, just not going to go Rah-Rah to every post!
If you look at the projects
Botswana long term, great location could be boom or bust.
Canada has Kimberlite pipes and interesting diamonds needs a positive outcome from bulk sample.
Ellendale/Blina, Alluvials highly likely short term, great diamonds, relatively easy project, probably quite small scale.
Ellendale Pipes, longer term, high price, high risk.

No guarantees in diamond exploration as can be seen by this quote on BHP, (you could also apply this to RioTinto)
“BHP has been singularly unsuccessful [in diamond exploration], and they’ve thrown a lot of money and resources at it in Canada and elsewhere,” said Patrick Evans, chief executive of Mountain Province Diamonds Inc. “But it’s no particular judgment on BHP’s skills. Everyone has been unsuccessful.”
