Maria Bartiromo to Feature NioCorp on Monday, September 22, 2025

Rhea-AI Summary

NioCorp Developments Ltd. (NASDAQ:NB) announced that CEO Mark A. Smith will appear on Fox Business News' "Mornings with Maria" show on Monday, September 22, 2025, at 6:30 a.m. Eastern. The company is developing the Elk Creek Critical Minerals Project in Nebraska, the nation's only fully permitted critical minerals project for niobium, scandium, titanium, and rare earths production.

The appearance gains significance as the U.S. currently relies 100% on imports for niobium, a critical mineral essential for advanced steels, aerospace, defense applications, and infrastructure. Currently, only three niobium mines operate globally, with Brazilian mines controlling over 90% of global supply, while China maintains significant influence over global niobium supply chains.

CENTENNIAL, CO / ACCESS Newswire / September 19, 2025 / NioCorp Developments Ltd. ("NioCorp" or the "Company") (NASDAQ:NB) is pleased to announce that Mark A. Smith, Executive Chairman and CEO of NioCorp Developments Ltd., will appear on Fox Business News' "Mornings with Maria" show hosted by Maria Bartiromo at 6:30 a.m. Eastern on Monday, September 22, 2025.

Mr. Smith is leading the effort to develop the Elk Creek Critical Minerals Project in Nebraska (the "Elk Creek Project"), the nation's only critical minerals project containing niobium, scandium, titanium, and rare earths and which is fully permitted to start construction, has completed Feasibility Study-level metallurgy for its planned products, and has established a Mineral Resource supported by a Regulation S-K 1300-compliant Technical Report Summary.^[[i]]

Niobium is coming increasingly in focus given the U.S.'s 100% reliance on imports of the critical mineral and its extensive uses in advanced steels, aerospace and hypersonic missile systems, virtually all naval defense vessels, and many other major defense applications A small addition of niobium doubles steel yield strength, making it indispensable for pipelines, bridges, turbines, autos/trucks/trains, fighter jets, naval ships/subs, and space delivery systems.

Only three niobium mines operate worldwide - two in Brazil and one in Canada. Brazil's mines meet >90% of global demand. However, China exerts significant influence over global niobium supply chains through ownership of Brazil's Catalão niobium mine by a Chinese state-controlled entity (China Molybdenum) and a Chinese consortium's ownership of 15% of Brazil's Araxa mine, which itself accounts for greater than 80% of global niobium production.

ABOUT NIOCORP

NioCorp is developing a critical minerals project in Southeast Nebraska (the "Elk Creek Project") that is expected to produce niobium, scandium, and titanium. The Company also is evaluating the potential to produce several rare earths from the Elk Creek Project. 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.
