Antofagasta's Minnesota mine could send critical minerals to China despite U.S. environmental warnings. The 202,000-acre Iron Range—a pristine wilderness—faces copper-sulfide mining after Congress overruled a 2022 U.S. Forest Service review. While the editorial praises the move, it warns state-owned Chinese smelters may process the minerals, with no guarantee they'll return to America. Antofagasta's subsidiary Twin Metals Minnesota hasn't finalized processors, but most U.S. mineral processing already occurs in China.

The deal's zero-cost processing agreements with Chinese firms raise national security concerns. Sending raw materials abroad risks losing control of the supply chain while enriching foreign operators. Environmentalists argue the mine would damage one of the nation's most cherished landscapes, undermining the "America First" narrative.

Twin Metals Minnesota plans to start operations in 2025, but critics highlight lack of transparency in processing agreements. Without U.S.-based refining infrastructure, the minerals' final destination remains uncertain. This decision prioritizes short-term gains over long-term strategic independence.

National security risks loom large as China expands its dominance in critical mineral processing. The Minnesota project exemplifies how U.S. policies may inadvertently strengthen adversarial control over essential resources. Protecting domestic supply chains requires stricter oversight of foreign partnerships and environmental safeguards.
