In that MSP Access Report I referred to earlier on page 28 they mention MP Materials on page 28 of their report.
MP Materials is listed on the US stock exchange and operate a rare earth mine in California US.
If you look at their latest investor presentation on their website, they had negative earnings per share to the 9 months ended 30th September 2020, are targeting an EBITDA of $250m US in CY 2023 and have a market cap of $5 billion US.
