Star Metro - U.S. Export-Import Bank Features NioCorp's Elk Creek Critical Minerals Project in EXIM's Factory Floor Fridays Initiative

CENTENNIAL, CO / ACCESS Newswire / November 13, 2026 / NioCorp Developments Ltd. ("NioCorp," "our," or the "Company") (NASDAQ:NB), a leading U.S. critical minerals developer, is pleased to announce that the Export-Import Bank of the United States ("EXIM") has featured the Company's Elk Creek Critical Minerals Project (the "Elk Creek Project") in southeast Nebraska as part of EXIM's Factory Floor Fridays initiative, highlighting the pivotal role Elk Creek will prospectively play in strengthening domestic critical mineral supply chains and supporting American manufacturing.

Through its Factory Floor Fridays initiative, EXIM showcases American companies and workers contributing to the next generation of U.S. industry, including projects aimed at strengthening domestic production, supporting American jobs, and improving the competitiveness of U.S. manufacturers.

"EXIM is proud to support projects like NioCorp's Elk Creek mine that will unlock domestic mineral resources, create well-paying jobs, and provide an important boost to reindustrializing America," said John Jovanovic, EXIM Chairman.

"The decision by EXIM to showcase the Elk Creek Project speaks to the growing recognition that America needs to develop its own sources of the critical minerals essential to our economy and national security," said Mark A. Smith, NioCorp Executive Chairman and CEO. "Chairman Jovanovic and his team understand what it takes to bring projects of this scale into production, and we greatly appreciate their continued support. Our focus remains on completing the financing process and bringing this important source of American critical minerals into production as quickly as possible."

The feature includes a video highlighting EXIM Chairman and President John Jovanovic's October 14, 2026 visit to the Elk Creek Project, where he was joined by U.S. Secretary of Energy Chris Wright, Nebraska Governor Jim Pillen, U.S. Senators Deb Fischer and Pete Ricketts, U.S. Representative Adrian Smith, Nebraska Senator Bob Hallstrom, other state and local leaders, and NioCorp leadership.

During the visit, Chairman Jovanovic and NioCorp Executive Chairman and CEO Mark A. Smith signed a Letter of Support (the "Letter") in which EXIM reiterated its target of providing debt financing equivalent to approximately 65% of the Project's upfront capital expenditures, subject to applicable financing requirements and satisfactory completion of EXIM's due diligence and approval processes. The Letter also indicated that EXIM expects to continue advancing its due diligence efforts toward further internal review through its Transaction Review Committee process as expeditiously as practicable.

The Elk Creek Project is designed to produce niobium, scandium, titanium and several rare earth products from a single ore body in southeast Nebraska. These materials are critical to U.S. defense, aerospace, automotive, energy security and advanced manufacturing supply chains, with the United States currently heavily reliant on imports for almost all of these minerals.

ABOUT NIOCORP

NioCorp is developing the Elk Creek Project that is expected to produce niobium, scandium, titanium and several rare earth products, including neodymium-praseodymium oxide, dysprosium oxide, terbium oxide, samarium-europium-gadolinium ("SEG") carbonate, and heavy rare earth carbonate. Niobium is used to produce specialty alloys as well as High Strength, Low Alloy steel, which is a lighter, stronger steel used in automotive, structural, and pipeline applications. Scandium is a specialty metal that can be combined with Aluminum to make alloys with increased strength and improved corrosion resistance. Scandium is also a critical component of advanced solid oxide fuel cells. Titanium is used in various lightweight alloys and is a key component of pigments used in paper, paint and plastics and is also used for aerospace applications, armor, and medical implants. Magnetic rare earths, such as neodymium, praseodymium, terbium, and dysprosium are critical to the making of neodymium-iron-boron magnets, which are used across a wide variety of defense and civilian applications.
