RE:An old but wise friend.On points 1 and 4.
1. It is a diamond mill (high recoveries), no froth flotation, no autoclave, no cyanide, no biox (bugs). Rather simple mill process. I'm assuming mill costs would be directly related to energy/heat use...but yes, bigger would probably be cheaper ($/milled tonne). I would say that Peregrine should focus on a modular unit that is scalable within reason. Start off somewhat smaller with the ability to increase later on. This will come in handy if they do mine kimberlites like CH-31 or CH-33 where tonnage throughput may be needed for economics.
4. What we don't know - How big is big in CH-6. We know it will be larger then 9 carats. What we do know - The quality and colour of diamonds found in the micro diamonds of CH-6 has carried forward into the macro diamonds. This should statistically carry forward into the larger diamonds. Which we don't know how big it will be. This is one area we are ahead of KDI. KDI still needs tonnage to confirm it can at least produce some size of macros of CH-6 to date and also see what quality they can get. I highly doubt ch-6 or kdi is going to produce anywhere near the size of lucara's diamonds. However, good indication that CH-6 can cough up a 20 or 30 carat stone, clear stone with no or minor inclusions in it. That would be significant $$'s.
