Yesterday saw Gina Rinehart emerge as a significant player in Lynas (LYC) after taking her stake to almost 6% over the last few days, although compared to her net wealth, the purchases were a poultry drop in the ocean. LYC is the world’s largest non-China producer of rare earths, although China still produces almost 70% of the world’s rare earths, with Australia’s ~5% output more of a supporting role. Gina’s move could be largely motivated by her intention to merge US-listed MP Materials (MP US), which has a market cap. of ~$4.3bn, and the local and larger $6bn rare earth player Lynas (LYC), i.e. it would form a relative $10bn rare earth giant.
