A bill to require reports on critical mineral and rare earth element resources around the world and a strategy for the development of advanced mining, refining, separation, and processing technologies, and for other purposes.
Summary
The Critical Minerals Security Act (S789) passed the Senate Energy Committee with bipartisan support, requiring reports and a strategy to secure U.S. access to critical minerals and rare earth elements. While no direct funding is authorized, the legislation sets the stage for future policy support benefiting domestic producers like MP Materials ($MP) and Lynas Rare Earths ($LYC).

Key Takeaways
- 1.S789 passes Senate Energy Committee, targeting critical minerals supply chain security.
- 2.No direct funding, but sets policy direction for future investments in domestic rare earth processing.
- 3.Pure-play rare earth stocks MP Materials and Lynas are best positioned to benefit from legislative momentum.
Market Implications
The bill's progress adds political momentum behind onshoring rare earth and critical mineral supply chains. While no immediate spending, the legislative signal supports valuation premiums for U.S.-focused miners and processors. MP Materials ($MP) and Lynas should see continued investor interest as policy catalysts build. The absence of a House companion bill remains a risk, but bipartisan Senate support improves odds of eventual passage.
Full Analysis
-
What happened: On June 10, 2026, the Senate Energy and Natural Resources Committee ordered S789, the Critical Minerals Security Act, to be reported favorably with an amendment. The bill was introduced in February 2025 by Senator Cornyn (R-TX) and has 6 cosponsors from both parties. It now awaits floor scheduling in the Senate.
-
Money trail: The bill is a reporting and strategy mandate – it authorizes zero dollars for spending. Actual funding for domestic critical mineral projects would require separate appropriations or authorization bills. However, the reports and strategy could pave the way for future targeted investments, such as DOE grants for processing facilities or DPA Title III loans.
-
Structural winners and losers: The clearest beneficiaries are pure-play rare earth producers with U.S. operations. MP Materials ($MP) is the only integrated rare earth producer in the U.S., and its Mountain Pass facility is the largest rare earth mine outside China. The bill's emphasis on supply chain security directly supports MP's strategy to expand downstream processing. Lynas Rare Earths is building a U.S. separation facility in Texas, positioning it to benefit from any federal push for domestic processing. Major miners like BHP ($BHP) and Rio Tinto ($RIO) also produce critical minerals but are diversified, limiting direct impact. The losers are Chinese producers and companies reliant on Chinese processing, as the bill signals increased U.S. government focus on reducing dependency.
-
Timeline and next steps: The bill must pass the full Senate, then the House (no companion bill yet – H.R. equivalent unclear). Given committee passage and bipartisan support, floor consideration is likely in the coming months. If passed, the first report is due one year after enactment. Actual policy action from the report will take 2-3 years. The most near-term catalyst is potential floor amendments that could add authorization of funds for specific projects.

What the bill does
Mandate for Interior to report on global critical mineral and rare earth element resources and develop a strategy for advanced mining, refining, separation, and processing technologies.
Who must act
U.S. Department of the Interior, in consultation with the Department of Energy and other agencies.
What happens
The report and strategy will identify domestic rare earth processing gaps and likely recommend policy support (e.g., grants, loans, or procurement preferences) to onshore production.
Stock impact
MP Materials operates the only U.S.-based rare earth mining and processing facility (Mountain Pass). The strategy could directly incentivize expansion of its downstream processing capacity, which is currently a key bottleneck. Any federal support would improve MP's cost structure and revenue growth trajectory.

Further Adjusting the Tariff Regimes for Imports of Aluminum, Steel, and Copper into the United States
This proclamation modifies existing Section 232 tariffs on aluminum, steel, and copper imports by expanding the list of derivative products eligible for a reduced 15% duty to include agricultural equipment and residential HVAC systems, temporarily reducing tariffs on mobile industrial equipment, adding aluminum lithographic plates and steel racks to the derivative tariff coverage, and lowering the threshold for products to qualify as made 'entirely' from American metals from 95% to 85%.
Approving Critical Position Pay Authority for National Security Investment Workforce
This memorandum authorizes the Office of Personnel Management to allocate up to 400 critical positions with pay up to $400,000 to recruit specialized talent for national security investment programs, focusing on critical minerals, advanced materials, and strategic supply chains. It directs OPM and OMB to oversee allocation and ensure pay is used only to recruit or retain exceptionally qualified individuals. The action aims to accelerate domestic mineral production and reduce foreign dependence.
Removing Unnecessary and Counterproductive Restrictions on Access to Federal Lands
This executive order rescinds two 1970s-era executive orders (11644 and 11989) that required federal agencies to use vague environmental and social criteria when designating off-road vehicle use on federal lands. It directs the Secretaries of War, Interior, Agriculture, the TVA Board, and other relevant agency heads to initiate rulemakings to remove or revise regulations based on those criteria, aiming to increase access for energy, timber, utility maintenance, and recreation.
