It's interesting that Trump wanna buy Greenland island.
I think he's obviously after GGG.ax's massive REE & Uranium deposit.
GGG (Market cap: $160m) project requires huge capex, initial USD$1B (expected to reduce to ~USD$500m), low IRR.
Who will be mining Manono lithium & tin, still a question, my best guess, is Chinese.
Sometimes, strategic value is also very important, imo.
