Large Integrated Steel Producer Signs Non-Binding Letter of Intent with NioCorp to Purchase 25% of NioCorp's Planned Ferroniobium Production From its Elk Creek Project

The non-binding letter of intent does not obligate either NioCorp or the steel producer until a binding commercial sales offtake agreement is finalized. However, if such a binding sales offtake agreement is reached, it would effectively sell out NioCorp's Elk Creek Project for its ferroniobium production over the first decade of its estimated 36-year mine life.

NioCorp previously entered into an offtake agreement with ThyssenKrupp Metallurgical Products GmbH ("Thyssen") for roughly fifty percent of NioCorp's planned ferroniobium production over 10 years, and a separate offtake agreement with New Jersey-based CMC Cometals for roughly 25 percent of the Project's ferroniobium production over 10 years. Both the Thyssen and CMC Cometals contracts provide an option to extend ferroniobium purchases beyond the 10-year periods in each contract upon mutual agreement of the parties. The offtake agreements with Thyssen and CMC Cometals, as well as any offtake agreement with the U.S.-based steel producer referenced above, will be subject to achieving planned production levels at the Project once NioCorp is able to secure project financing necessary to move the Project to construction and operation.

"We are very pleased to have reached this non-binding letter of intent with a very large U.S.-based steel producer, whom we cannot name because of our confidentiality agreement with them. But we much look forward to executing a commercial sales offtake agreement at the right time and to supplying this steel producer with Nebraska-produced ferroniobium," said Mark A. Smith, CEO and Executive Chairman of NioCorp.

The entry into a binding agreement is subject to the satisfactory completion of due diligence, the negotiation and settlement of final terms, and the negotiation of definitive documentation. There can be no assurance that an offtake will be completed on the terms as described above or at all.

About NioCorp

NioCorp is developing a superalloy materials project in Southeast Nebraska that will produce Niobium, Scandium, and Titanium. Niobium is used to produce superalloys as well as High Strength, Low Alloy ("HSLA") steel, which is a lighter, stronger steel used in automotive, structural, and pipeline applications. Scandium is a superalloy material that can be combined with Aluminum to make alloys with increased strength and improved corrosion resistance. Scandium also is a critical component of advanced solid oxide fuel cells. Titanium is used in various superalloys and is a key component of pigments used in paper, paint and plastics and is also used for aerospace applications, armor and medical implants.
