The critical-minerals contest was decided at the refinery, not the mine
Diversifying extraction without diversifying processing changes very little.
A decade of resource diplomacy focused on securing deposits. The chokepoint was always midstream processing, where concentration is far higher and capital is far less patient.
New refining capacity is now being financed on offtake and price-floor structures rather than on spot economics, because no private balance sheet will otherwise carry the cycle risk.
Where governments have provided that floor, capacity is being built. Where they have provided only permits, it is not.
