Well, Barb'ry, I'm not going to do all that personal attack-dog stuff, but the post I pointed to (in my 03.52 PM post) was just grandstanding, deliberately designed to impress the geological no-nothings (as he sees it) with jargonistic abbreviations which failed to give any indication of net yields of rare earths from ores and with this obscure and unexplained reference: "the Kvanefjeld project has JORC 2012-compliant resources of one billion tonnes." Cor blimey, guv! :-) If we are to have lusty debate we do need to be able to sternly call out nonsense in posts, but without the obnoxious name-calling stuff. I know he doesn't like it, but...

I'm not a geological know-nothing, by the way, unfortunately for him...

And you're doing a grand job!
