Alex Padilla U.S. Senator for California

WASHINGTON, D.C. — U.S. Senators Alex Padilla (D-Calif.), a member of the Senate Energy and Natural Resources (ENR) Committee, Adam Schiff (D-Calif.), Martin Heinrich (D-N.M.), Ranking Member of the Senate ENR Committee, and Jared Huffman (D-Calif.-02), Ranking Member of the House Natural Resources Committee, expressed serious concern over the Bureau of Land Management’s (BLM) unlawful approval of mining activities by Dateline Resources inside the Mojave National Preserve and demanded they rescind their approval. In their letter to Secretary of the Interior Doug Burgum, the lawmakers also called on Interior to comply with federal mining law, conduct a full mineral validity exam, reaffirm the National Park Service’s (NPS) authority over mining operations in the Preserve, and explain their legal rationale for permitting Dateline Resources mining activity.

“We write with serious concern regarding the Bureau of Land Management’s (BLM) recent press release announcing BLM’s ‘approval’ of mining activity by Dateline Resources within Mojave National Preserve,” wrote the lawmakers. “This action appears to violate federal law, disregards National Park Service (NPS) authority, and sets a dangerous precedent for industrial development in lands that Congress has designated as worthy of inclusion in the National Park System.”

Congress created the Mojave National Preserve in 1994 through the late Senator Dianne Feinstein’s California Desert Protection Act (CDPA), which transferred the land from BLM to NPS, helping support rare plant species and vital wildlife corridors. The law clearly states that any mining within the Preserve must comply with the Mining in the Parks Act, meaning companies with preexisting claims must conduct a mineral validity exam and obtain an NPS-approved plan of operations before any surface-disturbing activity can occur.

Despite these requirements, BLM recently approved rare earth mineral exploration by Dateline Resources, an Australian company, based on a 1985 BLM plan of operations that predates the Preserve’s creation and only covers the extraction of gold. Dateline recently announced plans to begin exploratory drilling, despite lacking a valid NPS-approved plan or proof of the existence of a valuable mineral deposit, as the Mining in the Parks Act requires.

“Congress set aside these lands and entrusted them to the NPS for permanent protection, not as a zone for future industrial exploitation,” continued the lawmakers.

The lawmakers also criticized Secretary Burgum for backtracking on his commitments to safeguard America’s national parks.

“This is not only illegal, but it directly contradicts a commitment you made during your confirmation hearing to ‘protect every inch of our national parks.’ Approving a foreign-owned company’s speculative mining project inside a national park in this way is clearly inconsistent with that promise and threatens future speculative actions across other national parks,” added the lawmakers.

Local leaders expressed their strong support for Padilla, Schiff, Heinrich, and Huffman’s effort to protect the Mojave National Preserve from this unlawful mining activity.

“We applaud Senator Padilla and congressional leaders for defending our beloved Mojave National Preserve from unchecked destruction by the Trump administration,” said Chance Wilcox, California Desert Program Manager for the National Parks Conservation Association. “In promoting speculative, damaging mining in our National Park System, the administration is pushing aside not only the legal protections afforded to this biodiverse landscape, but also the American people who love their parks. The administration’s misguided effort gives an Australian company a free pass to mining in one of America’s largest national park sites while saddling taxpayers with the clean-up costs.”

“I spent my entire career in the National Park Service and was Superintendent of Mojave National Preserve for over a decade,” said Mary Martin, Retired National Park Service Official. “Speculative mining should have no place in our country’s most spectacular places – our national parks. It is infuriating that the Trump administration is urging an Australian mining company to drill and bulldoze this national park. This is nothing short of illegal and a betrayal of all Americans who own these national parks.”

“The Clark mountain range is one of California’s most botanically important areas, estimated to harbor the second-highest density of rare plants of any of the state’s mountain ranges,” said Jim Andre, Director of UC Riverside’s Granite Mountains Desert Research Center. “The eastern Mojave Desert is also a global hotspot for new species discovery, where 15% of the vascular plant species have yet to be discovered. Will we know what we’ve lost if we bulldoze this area? They’re not just prized luxury items, they’re actually a functional part of the ecosystem that are supposed to be protected for the benefit of all Americans.”

Dear Secretary Burgum,

We write with serious concern regarding the Bureau of Land Management’s (BLM) recent press release announcing BLM’s “approval” of mining activity by Dateline Resources within Mojave National Preserve. This action appears to violate federal law, disregards National Park Service (NPS) authority, and sets a dangerous precedent for industrial development in lands that Congress has designated as worthy of inclusion in the National Park System.

Congress created the Mojave National Preserve in 1994 via the California Desert Protection Act (CDPA), elevating this cherished landscape to a National Park because of its outstanding ecological and cultural values, including in the Clark Mountain region, which supports rare plant species and critical wildlife corridors. Congress set aside these lands and entrusted them to the NPS for permanent protection, not as a zone for future industrial exploitation.

The CDPA clearly states that any mining within the Mojave Preserve must comply with the Mining in the Parks Act, which requires a mineral validity examination and an NPS-approved plan of operations. However, it appears that BLM is attempting to circumvent this law and instead authorize Dateline’s project based on a 1985 plan originally approved by BLM for different minerals, under different ownership, and issued before the Preserve existed.

To date, no mineral examination has been completed to validate Dateline Resource’s claims. Meanwhile, the NPS has repeatedly objected to Dateline’s unauthorized activities on lands within the Mojave National Preserve, including road grading and vegetation clearing, and requested over $200,000 in damages. Still, BLM appears to have acted unilaterally, greenlighting the company’s efforts to evade the law and ignore NPS oversight and review. In May, Dateline announced plans to begin exploratory drilling, despite lacking a valid NPS-approved plan of operations or proof of a valuable mineral deposit, as required by the Mining in the Parks Act. The original 1985 plan was for gold extraction, but Dateline is now touting rare earth elements – a major pivot that lacks any new environmental review or mineral validity determination.

This is not only illegal, but it directly contradicts a commitment you made during your confirmation hearing to “protect every inch of our national parks.” Approving a foreign-owned company’s speculative mining project inside a national park in this way is clearly inconsistent with that promise and threatens future speculative actions across other national parks.

Therefore, we urge you to:

• Revoke BLM’s reliance on the outdated 1985 plan;
• Affirm NPS’s jurisdiction and require compliance with the Mining in the Parks Act;
• Conduct a full mineral validity exam; and
• Provide, by June 20, 2025, the Department’s legal rationale for this decision, a copy of the 1985 plan of operations, and a clear statement on whether the Department supports industrial mining within national parks.

We strongly urge you to reverse this decision and uphold the integrity of the Mojave National Preserve and the National Park System.

Sincerely,

###
