Highlights
- DOI approves Dateline Resources’ Colosseum Rare Earth Project near Mountain Pass, aiming to reduce U.S. dependency on Chinese rare earth supplies.
- The U.S. currently imports over 80% of its rare earth needs, with 77% coming directly from China, highlighting significant supply chain vulnerabilities.
- Despite government support, the project remains in early stages with no defined rare earth resource and limited domestic processing infrastructure.
In a bold but long-overdue move, the U.S. Department of the Interior (DOI) has officially approved (opens in a new tab) Australian-listed Dateline Resources (opens in a new tab) (ASX: DTR) to advance the Colosseum Rare Earth Project in California’s Mojave Desert—just 10 kilometers from the nation’s only active rare earth mine, Mountain Pass. This decision follows President Trump’s executive order mandating the reshoring of critical mineral supply chains and marks a symbolic step in the United States’ faltering race to reduce dependency on China.
But symbolic gestures aren’t enough. The United States still imports over 80% of its rare earth needs, with 77% of that supply coming directly from China, which also controls approximately 90% of the global rare earth element (REE) processing capacity. While the DOI’s greenlight offers hope for a diversified domestic supply chain, it comes against the sobering backdrop of China mining 270,000 metric tons in 2024—six times more than the U.S.. Unlike Mountain Pass, which still sends its rare earth concentrate to China for refining, Colosseum lacks any current quantified rare earth resource base.
Colosseum’s Strategic Promise—And Unmet Challenges
With a mining legacy tracing back to the California Gold Rush, the Colosseum site has produced over 344,000 ounces of gold and holds a current gold resource of 1.1 million ounces. However, its rare earth potential remains speculative, with no defined REE resource and reliance on geological similarities with Mountain Pass as the primary basis for optimism. A scoping study suggests a gold-focused eight-year mine life—but rare earth extraction and processing remain uncharted and unfunded.
According to Dateline’s Managing Director, Stephen Baghdadi, U.S. government support lays a “solid foundation,” but without a functioning domestic refining ecosystem and defined reserves, that foundation is shaky at best. The approval offers legal momentum—but not yet the industrial scale or funding needed to compete with China’s state-backed rare earth juggernaut.
The Bigger Picture: A Nation Behind Schedule
Pentagon-led initiatives to build processing facilities and create strategic reserves are still in early stages. Despite bipartisan urgency, the U.S. lacks:
- Downstream refining and separation capacity
- Advanced metallization and magnet production infrastructure
- Permitting reforms to fast-track rare earth development
- A strategic stockpile of rare earth oxides or finished products
While Colosseum could eventually serve as a second major node in America’s rare earth network, it remains in exploratory and gold-centric phases. If the U.S. is serious about breaking China’s grip, it needs more than approvals—it needs an integrated, government-backed industrial strategy, supply chain-focused.
