Overview

• Amends the Mineral Leasing Act for Acquired Lands (30 U.S.C. 351 et seq.) to include hardrock minerals under federal leasing requirements
• Reported out of House Natural Resources Committee on October 31, 2025, with amendments
• Currently on Union Calendar awaiting House floor consideration

Who does this affect?

• Mining companies seeking to extract gold, silver, copper, industrial minerals, and gemstones from federal acquired lands
• States and local governments that receive revenue shares from mineral leasing on federal lands within their borders
• Environmental groups concerned about mining regulation and oversight on public lands
• Teen impact score: 1/10 (affects mining industry and federal land management with no direct teen connection)

What This Bill Does

• Adds new definition of 'hardrock mineral' to 30 U.S.C. 351, covering base metals (copper, zinc, lead), precious metals (gold, silver), industrial minerals, and gemstones
• Explicitly excludes coal, oil, gas, sodium, potassium, sulfur, and materials covered by the Materials Act of 1947 from the hardrock definition
• Amends 30 U.S.C. 352 to add 'hardrock minerals' to the list of resources subject to mineral leasing laws on acquired lands
• Changes apply only to lands the federal government purchased or acquired (not original public domain lands)
• Would require mining companies to obtain federal leases for hardrock extraction, similar to current oil and gas leasing process

Legislative Status

• Introduced June 10, 2025, by Rep. Fallon with Rep. Moran as original cosponsor
• Rep. Harrigan added as cosponsor on October 31, 2025
• Reported favorably with amendments from House Natural Resources Committee (Report 119-357) on October 31, 2025
• Placed on Union Calendar No. 309, awaiting House floor debate and vote

In short

• Bill brings hardrock mining (gold, silver, copper, gemstones) under the same federal leasing system that already covers oil, gas, and coal on acquired federal lands.
• Mining companies would need federal leases to extract these minerals, creating consistent rules across different resource types.
• Applies only to lands the government bought or acquired, not original public lands where different mining laws apply.
• Currently awaiting House floor vote after clearing committee review.

Why should I care?

This bill changes how mining companies access valuable minerals on certain federal lands. Right now, hardrock minerals follow different rules than fossil fuels, creating inconsistent oversight. Bringing them under the same leasing system could generate more revenue for states and the federal government through lease payments and royalties. It also means more federal oversight of mining operations, which affects environmental protections and land use decisions. The distinction between 'acquired lands' and original public lands matters because it determines which mining laws apply where. For communities near federal lands, this could influence local mining activity and environmental impacts.
