Summary

What This Bill Does

This bill extends the Mineral Leasing Act for Acquired Lands to include hardrock minerals such as gold, silver, copper, zinc, and gemstones. Currently, the Act only covers oil, gas, coal, and certain other minerals. This change would allow the Secretary of the Interior to issue leases for hardrock mineral extraction on federal "acquired lands" (lands the government purchased or obtained, as opposed to original public domain lands).

Who Benefits and How

Mining companies benefit significantly by gaining access to hardrock mineral deposits on federal acquired lands through a leasing system. This includes gold and silver miners, copper and zinc producers, and gemstone extractors who previously could not access these resources on acquired lands.

The federal government would receive lease payments and royalties from hardrock mineral extraction, creating a new revenue stream from these lands.

Who Bears the Burden and How

Environmental groups may face expanded mining operations on lands that were previously not subject to hardrock mineral leasing, potentially affecting conservation goals.

Mining companies also face a trade-off: while gaining access to new lands, they must now navigate a federal leasing process rather than the traditional mining claim system used on public domain lands.

Key Provisions

  • Defines "hardrock mineral" to include base metals, precious metals, industrial minerals, and gemstones while excluding coal, oil, gas, and materials already covered by other laws
  • Extends leasing authority to allow the Secretary of Interior to issue hardrock mineral leases on acquired lands
  • Adds sulfur and hardrock minerals to the list of minerals that can be leased under Section 3 of the Mineral Leasing Act for Acquired Lands
