Our Critical Minerals

NioCorp plans to produce some of the world’s most critical minerals, including Niobium, Scandium, and Titanium.


NioCorp plans to make Ferroniobium, which is used as an additive to steel, making the steel much tougher, stronger, and more corrosion-resistent.  Niobium-strengthened steel also allows for lighter-weight applications, reducing  energy consumption and harmful air emissions.


  • Powerful alloy with Aluminum
  • Lightweights vehicles / aircraft
  • Demand limited by low production
  • USA 100% dependent on imports
  • NioCorp is 12% sold out

Scandium is a remarkable element with many uses, including as an additive to aluminum.  It makes for alloys that are much stronger and corrosion-resistant than other aluminum alloys.  Scandium also allows these alloys to be reliably welded, which opens up many applications in transportation and aerospace.


  • Large global markets
  • Premium on high purity
  • Critical to US defense
  • US largely dependent on imports of mineral concentrate

Titanium is a highly sought-after refractory metals and is used across many industries, including industrial processes, aerospace and defense, medical applications industry, and many more. The U.S. is highly reliant upon foreign imports of this critical mineral, including (historically) from Russia and Ukraine.


Magnetic Rare Earth Elements

NioCorp is also conducting technical and economic analyses on the potential addition to its planned product suite of several magnetic rare earth oxides, shown below, which are forecast to experience large supply shortages because of sharply rising demand.

NdPr Oxide

Neodymium-Praseodymium Oxide

Also known as “NdPr” or “Didymium Oxide,” this purified rare earth oxide is indispensable to the manufacturing of high-performance rare earth permanent magnets.  These magnets are crucial to electric vehicles and other energy efficient applications. 

Dysprosium Oxide

Dysprosium Oxide

This  “heavy” rare earth is used in a variety of electronic, automotive, and other applications, including high-performance rare earth permanent magnets. The Elk Creek Project contains the 2nd largest indicated Dysprosium Mineral Resource in the U.S.

Terbium Oxide

Terbium Oxide

Like Dysprosium, Terbium is “heavy” rare earth is used in a variety of electronic, automotive, and other applications, including high-performance rare earth permanent magnets. The Elk Creek Project contains the largest indicated Terbium Mineral Resource in the U.S.
