Chill dude. Your footie team lost today?

So Mountain Pass is fairly shallow and not too huge volume/tonnes. I think I saw ~ 17mT, which might equate to a 500-800Koz Au deposit. Smallish, in size.

Full disclosure, I know shite about drilling out REE deposits but I know gold and have been on a number of discoveries and big drill-outs, a few with > 10 drill rigs going. Perhaps REE's don't require the level of detailed drilling that your average Au deposit requires? I don't know. I do know that 100,000m to drill out say a 1 Moz Au deposit is light. Believe me or not, don't care. I will bet you though that there's close to that amount of drilling into the Colosseum gold deposit. It was Lac Minerals and Barrick after all, so they would have done it right. Greg Hall comes from Placer/Barrick, so I have confidence Dateline will do things correctly as well.

Required drill density also depends on the deposit type - grade distribution/homogeneity. For a nuggetty, erratically mineralized high-grade vein gold deposit, you might have to drill it quite tightly (10-20 meter drill centres) to have statistical confidence in your resource estimation. Something like the Witwatersrand paleoplacer Au deposits where the gold values are very consistent over great strike lengths, you might be able to get away with 200m-spaced drilling. Maybe REE deposits are more akin to Wits type deposits in terms of grade distribution?

You are hypothesizing holes lengths and you don't even know how deep the deposit is? It could be much deeper than MP, remains to be seen. Amount of drilling required will largely be determined by depth of this yet to be discovered orebody. Let's wait and see how it all unfolds, OK? I would be shocked if they could declare even a small Inferred resource for $12M.

By the way, you can't use air-core drilling for resource estimations. OK for exploration, not for resource work. It's a 'dirty' exploration drill method. Not as bad as RAB though.
Good quality RC drilling would work, or diamond of course.
