Found this on the Daily telegraph: Alvo could take a giant leap in REE mission

“You can have clay-hosted REE projects but often they’re not easy to extract,” he said. “That’s where the ionic process comes in – a simpler extraction technique that is pivotal for capital expenditure metrics to get these types of projects off the ground.

“While they definitely help, it’s often not all about the grades themselves, it’s about the size of the deposit and its extractability. You’d rather have a large, low-grade deposit that’s easy to extract than vice versa.”
