Mountain Pass is not a great deposit. It requires blasting to extract from the bastnasite and is low in heavy rare earths such as Dysprosium and Terbium.
There are many better deposits in Australia with more HRE or Brazil (huge ionic clay deposits). Lynas's Mt Weld is weathered carbonatite so also lot more economical for mining.
Halleck Creek is the one to watch in the US as it looks to have a lot more HRE.
