MERICA Act of 2025

Jun 10, 2026

Summary

Changes the rules for mining on certain government lands to allow companies to lease the land for mining hardrock minerals like gold, silver, and copper.

What problem does this solve?

The current law for leasing government-owned land for mining does not include rules for hardrock minerals like gold and copper. This bill updates the law to include hardrock minerals, creating a clear process for companies to lease these lands for mining.

What does this bill do?

Adds hardrock minerals to leasing act

Amends the Mineral Leasing Act for Acquired Lands to include hardrock minerals, such as gold and copper, alongside substances like sulfur that can be leased on federal lands.

Defines hardrock minerals

Creates a legal definition for 'hardrock mineral', which includes base metals, precious metals, industrial minerals, and gemstones, but excludes things like coal, oil, and gas.

Who does this affect?

Mining companies
Federal land management agencies
Communities near federal lands

What is the real world impact?

•

Promotes domestic mining

Encourages the mining of important minerals like gold and copper within the United States by creating a clear leasing process on certain federal lands. This could reduce reliance on foreign sources for these materials.

•

Increases environmental impact from mining

Opening more federal lands to hardrock mining could lead to increased environmental damage, such as water pollution and habitat destruction, which are common side effects of mining operations.

When does this start?

This bill would take effect as soon as it is signed into law.
