ELK CREEK, October 15, 2026 — Federal officials voiced support for NioCorp’s Elk Creek rare earth project during a site visit, though final loan approval remains pending.
Project Scope and Output
The Elk Creek mine is intended to produce niobium, used for strengthening steel, and a host of other rare earth minerals, including scandium, titanium and materials used in high-performance permanent magnets. According to NioCorp Developments, the project targets critical minerals for U.S. defense, aerospace, automotive and advanced manufacturing industries. The mine is expected to cost $2 billion to build and would employ up to 500 people during its 40-year life.
Financing Review Status
Export-Import Bank Chair John Jovanovic signed a letter of support for the project during the October 14 visit. He stated that approval of an $840 million loan from the bank depends on final due diligence, which he predicted would be completed shortly. The visit occurred during EXIM’s continuing evaluation of NioCorp’s application for potential debt financing under its Make More in America initiative. No financing approval or new federal commitment has been announced.
Strategic Rationale
U.S. Energy Secretary Chris Wright said the project is necessary because China has prioritized controlling the market for rare earth minerals mining and processing. NioCorp Developments noted that the United States remains heavily dependent on imports for several of the minerals Elk Creek is expected to produce, including complete net import reliance for certain materials. The October 14 event was not open to the public due to construction-site safety and security restrictions, though a livestream was scheduled.
State and Congressional Advocacy
During the October 14 site visit, Nebraska’s federal and state officials publicly emphasized the project’s significance for both regional and national interests. Senator Deb Fischer highlighted the mine’s dual impact, stating it would be “a big deal for our state, but a huge deal for our country.” She was joined by Senator Pete Ricketts, Representative Adrian Smith, and Governor Jim Pillen in voicing support for NioCorp’s Elk Creek initiative.
The officials’ presence underscored bipartisan backing for the critical minerals project, which aims to reduce U.S. reliance on foreign supply chains. Their advocacy aligns with broader federal efforts to strengthen domestic production of materials essential to defense, aerospace, and advanced manufacturing sectors. No new financial commitments were announced during the visit, but the lawmakers’ participation signaled continued political support as the Export-Import Bank’s financing review progresses.
Proposed Mineral Production Details
NioCorp’s Elk Creek project is designed to extract niobium as its primary product, a critical additive used to enhance the strength and toughness of high-strength low-alloy steels employed in pipelines, automotive components, and construction materials. In addition to niobium, the mine will produce scandium, which improves the performance of aluminum alloys in aerospace and defense applications by increasing strength while reducing weight.
The facility will also recover titanium, valued for its corrosion resistance and high strength-to-density ratio in aerospace frames, medical implants, and chemical processing equipment. Furthermore, Elk Creek aims to supply magnetic rare earth elements essential for manufacturing high-performance permanent magnets used in electric vehicle motors, wind turbine generators, and advanced radar systems.
These outputs align with the project’s focus on supplying minerals deemed vital to U.S. defense supply chains, where domestic production remains limited. NioCorp has emphasized that the integrated recovery of these co-products from the Elk Creek deposit supports a more efficient and economically viable mining operation compared to single-mineral extraction.
