It's mostly light rare earth elements. Over half of it is cerium and most of the rest is lanthanum. Most of the economic value is in the elements that are not cerium or lanthanum. It appears to have about the same proportion of neodymium and praseodymium (valuable light rare earth elements used in magnets) as the Mountain Pass, California mine, plus more terbium (more expensive heavy rare earth element also useful in magnets) than Mountain Pass.

Awesome, thanks this clears it up. And are these reserves measured, inferred or indicated? Is there a PFS?

Also on that slide: "has average 3.14% grade". I assume that doesn't mean the rock consists of 3.14% of the target element, but is 3.14% of whatever ore they're targeting, right?

  You're right, there's no way they would not tout the "15% grade" of the actual ore, if by some miracle there was 3.14% grade the entirety of their staked land. Ore is by definition the "economically feasible/interesting" subsection of the rock covered by the claim.
