The Rhyolite Ridge Lithium-Boron Project, developed by Ioneer, is anticipated to generate 275–300 permanent jobs in Esmeralld County, Nevada, following the completion of its construction phase. The U.S. Department of Energy’s Loan Programs Office (LPO) previously estimated that the project could create <a href="https://www.energy.gov/edf/articles/lpo-announces-conditional-commitment-ioneer-rhyolite-ridge-advance-domestic-production">600 construction jobs</a> and approximately 250–300 operations jobs. With the Bureau of Land Management having issued the final Record of Decision in October 2024, the project is now in the construction phase and expected to transition to full operations in the coming years.The project, which received <a href="https://www.energy.gov/edf/articles/lpo-announces-conditional-commitment-ioneer-rhyolite-ridge-advance-domestic-production">a $700 million loan</a>, is designed to produce lithium carbonate and boric acid, both critical materials for electric vehicle batteries and other advanced technologies. Ioneer has already invested over $200 million in the project and <a href="https://www.ioneer.com/">secured a $996 million loan</a>. The project is also supported by <a href="https://www.energy.gov/edf/articles/lpo-announces-conditional-commitment-ioneer-rhyolite-ridge-advance-domestic-production">offtake agreements with major</a> industry players, including Ford, Toyota, and Panasonic.The Rhyolite Ridge project emphasizes environmental and social responsibility, including water conservation, low emissions, and community engagement initiatives. It is expected to <a href="https://www.energy.gov/edf/articles/lpo-announces-conditional-commitment-ioneer-rhyolite-ridge-advance-domestic-production">operate for 26 years</a> before decommissioning and land reclamation.<img src="https://cdn.ainvest.com/aigc/hxcmp/images/compress-1cca920d93a4a002.png" alt="Ioneer - Rholite Ridge expected to create 275-300 permanent jobs in Nevada">

The Trump administration is expanding its push for critical minerals by partnering with private industry to build mineral processing facilities on US military bases. The facilities, which will process rare earth elements, graphite, lithium, and boron, are part of a broader effort to reduce reliance on overseas suppliers, particularly China. The companies will pay for infrastructure improvements at the military bases in exchange for operating rights, with construction expected to begin as early as 2027.The Trump administration is advancing its strategy to bolster domestic critical minerals production by authorizing private companies to construct processing facilities on U.S. military bases. These facilities will focus on rare earth elements, graphite, lithium, and boron—materials essential for defense systems, consumer electronics, and clean energy technologies. The initiative, which involves companies such as REalloys Inc., Titan Mining Corp., Ioneer Ltd., and Energy Exploration Technologies, aims to reduce U.S. dependence on foreign suppliers, particularly China, which <a href="https://www.mining.com/web/us-army-bases-to-host-critical-minerals-plants-in-onshoring-push/">dominates global processing and refining</a>.Under the agreements, companies will cover the costs of infrastructure improvements in exchange for operating rights on the bases. The Pentagon will receive <a href="https://www.wsj.com/politics/national-security/army-will-lease-land-on-bases-for-critical-mineral-production-e714d576">a share of the processed mineral output</a> rather than direct cash payments, aligning the military’s strategic interests with private-sector investment. The projects are expected to collectively require approximately $2 billion in private capital and will be supported by existing federal financing mechanisms, including the Department of War’s Office of Strategic Capital, which has <a href="https://www.wsj.com/politics/national-security/army-will-lease-land-on-bases-for-critical-mineral-production-e714d576">extended conditional loans to mineral producers</a>.This effort is part of a broader federal strategy to strengthen critical minerals supply chains. Recent actions include the establishment of a $12 billion national stockpile of critical minerals and the <a href="https://www.mining.com/web/us-army-bases-to-host-critical-minerals-plants-in-onshoring-push/">deployment of Defense Production Act authorities</a> to accelerate domestic production. The administration has also leveraged equity investments and loan guarantees to support key projects, such as a <a href="https://www.bhfs.com/insight/u-s-expands-critical-minerals-financing-and-bilateral-partnerships-under-trump/">$400 million equity stake in MP Materials</a> and a $150 million loan for rare earth separation capacity in California.The initiative reflects growing geopolitical tensions over access to critical minerals, with China recently imposing export controls on U.S. rare earth companies. In response, the Group of Seven nations has set a target to reduce reliance on Chinese imports, while the U.S. has pursued <a href="https://www.bhfs.com/insight/u-s-expands-critical-minerals-financing-and-bilateral-partnerships-under-trump/">bilateral agreements with Australia and Japan</a> to diversify supply chains.Construction of the military-based processing facilities is expected to begin as early as 2027, with the Pentagon emphasizing the need to utilize underused military properties for strategic economic purposes. The move underscores the administration’s commitment to reshaping the U.S. industrial base and ensuring a secure supply of materials vital to national security and technological innovation.
