"I mean if you need twenty tonnes of concentrate just for testing that seems very expensive. Do they have to test it so many times to get the right thing. A bit confusing."
You've been confused about a couple of things now v8man. Sorry to hear about that. Pretty basic stuff, the larger the sample, the lower the variable. Magnis for example (of which I'm a happy long term holder btw) has drawn criticism by some for having not undertaken larger sampling to underpin their BFS. I actually like the way KNL have gone about it and think financiers might as well.
