Hi Tonio, Fingers again. I take your point re the 10 to 30Kg/T. Well spotted. I habitually work from the grade, provided costs & stated recovery %, so hadn't really looked at those figures carefully enough to notice the incongruity. Typo or similar, I suppose, but not material to anyone who does their own calcs.

1) I agree with your cost figures.

2) CUX obviously wouldn't sell its 40% concentrate at the prices you suggest as nobody is going to bother mining to sell at a discount to cost & these guys, who have been around a long time, wouldn't even bother preparing to do so.
I accept Eupene's prices, as when I have asked him re prices of various REE's on previous occasions, and suggested ranges put out by others, I was advised that those prices were way above reality & that the prices are usually negotiated between the parties concerned: IMPLICATION: He,now being one of those parties, would have a far better idea of what is going on than people looking from the outside & relying on what they are told (by interested parties) to compile a list.
This approach implies that I accept that he has a high level of integrity and nous, which I do.
Generally I regard CEO's etc as morphed car salesmen so that is unusual.

3) I don't know the cost regime for CO3 production, but there is a huge margin available.

4)If you don't believe that there are substantial areas above the .03%, then your already demonstrated mathematical capability suggests that you are indeed a downramper, as obviously unless almost all of the resource is right on the 0.03%, shown not to be the case by the drill results, then around HALF THE RESOURCE is above 0.03%.
