Congress blocks foreign mining giant from extracting U.S. copper on public land

What it does

This bill repeals a 2014 provision that required the U.S. Forest Service to hand over Oak Flat, a 2,422-acre parcel in Arizona's Tonto National Forest, to Resolution Copper (a joint venture of foreign mining companies Rio Tinto and BHP) for copper extraction. Instead, it permanently withdraws Oak Flat from mining, preventing the foreign-controlled venture from extracting copper that would be exported to China. The bill protects ancestral Native American land, prevents massive groundwater depletion (250+ billion gallons over 40 years), and blocks creation of a toxic waste dump in the Gila River watershed.

Why we flagged it

The bill's core function is to withdraw public land from mining and repeal a prior giveaway provision. It is fundamentally protective legislation aimed at environmental and cultural preservation, not a commemorative or self-serving measure.

What the text implies

• Repeal of Section 3003 of the FY15 NDAA may set precedent for revisiting other controversial land-exchange riders buried in defense bills, potentially reopening debate on similar provisions.
• Withdrawal of Oak Flat may reduce near-term U.S. copper supply and increase reliance on imports, potentially affecting domestic copper-dependent industries and supply-chain resilience.

Who it affects

Ordinary Americans benefit from protection of public land, preservation of critical water resources in a drought-stricken region, prevention of environmental contamination, and respect for Native American sacred sites. The primary losers are foreign mining corporations and their shareholders—not U.S.
