NioCorp Developments Ltd. is a U.S.-based mineral exploration and development company focused on critical minerals. Through its subsidiary Elk Creek Resources Corporation, the company is advancing the Elk Creek Project in southeast Nebraska, targeting the production of niobium, scandium, and titanium from a high-grade carbonatite deposit. This shovel-ready initiative features the highest-grade niobium resource in North America and includes evaluations for potential rare earth elements production, such as magnetic rare earth oxides like neodymium-praseodymium. NioCorp has acquired scandium alloy manufacturing assets and intellectual property to support vertical integration into aluminum-scandium master alloys for defense and commercial applications. The project incorporates sustainable practices, including zero process water discharge, reagent recycling, groundwater protection via artificial ground freezing, and tailings reuse as underground backfill. Recently, construction of the mine portal has commenced, marking progress toward establishing a domestic supply chain for these essential materials used in high-strength steels, lightweight alloys, and advanced technologies. Headquartered in Centennial, Colorado, NioCorp Developments Ltd. plays a key role in securing U.S. critical minerals independence within the specialty mining and metals sector.
