Alaska Rare Earth Deposits Challenge China-But Mining More Rock Will Not Break Beijing's Supply-Chain Power

Highlights

• Alaska's Bokan Mountain is one of America's most significant heavy rare earth deposits, with exposure to dysprosium, terbium, and yttrium.
• China controls roughly 90% of magnet-REE separation and dominates metallization and NdFeB magnet manufacturing, making downstream infrastructure the real bottleneck.
• Opening American mines without building separation, metallization, and magnet production risks creating ore that still depends on foreign downstream infrastructure.
• Ucore Rare Metals is developing Bokan Mountain, but its near-term focus is RapidSX separation technology and a planned Louisiana Strategic Metals Complex.
• America's rare earth problem is industrial architecture, not geology—China built dominance through an orchestrated ecosystem, not better rocks.
