NioCorp Teams With Industry Alliance to Urge Congressional Approval of Tax Incentives for Permanent Rare Earth Magnets Made in the U.S.

CENTENNIAL, Aug. 30, 2021 - NioCorp Developments Ltd. ("NioCorp" or the "Company") (TSX:NB) (OTCQX:NIOBF) joined with a group of rare earth industry players to urge the U.S. Congress to approve bipartisan legislation in order to provide tax incentives for U.S. manufacturing of permanent rare earth magnets in the United States.

In a letter delivered to the Democrat and Republican leaders in the U.S. House of Representatives, the industry coalition urged support for HR 5033, cosponsored by Reps. Eric Swalwell (CA-15) and Guy Reschenthaler (PA-14), and urged that its provisions be added to pending federal infrastructure legislation. The bill would create a $20 per kilogram production tax credit for magnets that are manufactured in the U.S., or $30 per kilogram for magnets that are both manufactured in the United States and for which all component rare earth material is produced and recycled or reclaimed wholly within the United States. To be eligible, the rare earth magnets may not include any component rare earth magnet material produced in non-allied foreign nations, such as China, Iran, North Korea, and Russia.

Rare earth magnets are used in a variety of applications, such as electric vehicles, wind power turbines, home appliances, factory automation systems, computers, cellphones, and energy-saving electric motors. The majority of all electric vehicles made today contain a powertrain driven by rare earth magnets, and virtually all modern automobiles use rare earth magnets in smaller electric motors throughout the vehicle.

The Biden Administration recently issued an executive order setting a goal that 50% of all new vehicles sold in 2030 will be zero-emissions vehicles, including battery electric, plug-in hybrid electric, or fuel cell electric vehicles, all of which rely on rare earth magnets. The bipartisan infrastructure bill recently passed by the U.S. Senate includes $5.75 billion to replace thousands of transit vehicles, including buses, with zero-emission vehicles.

NioCorp is currently evaluating the potential for production of rare earth elements ("REEs") as a byproduct of planned production of the critical minerals niobium, scandium, and titanium from the Elk Creek Project (the "Project"), subject to receipt of necessary project funding. The Company's REE initiative was launched in response to intense interest by governments and industrial consumers around the world for additional sources of rare earths beyond current suppliers.

Commercial rare earth products currently being examined for potential production by NioCorp include neodymium-praseodymium oxide ("NdPr"), dysprosium oxide ("Dy2O3"), and terbium oxide ("Tb4O7"). These are the primary REEs used to manufacture the world's most powerful permanent magnets, known as neodymium-iron-boron ("NdFeB") magnets.

Other legislative proposals in the U.S. Congress would provide a variety of tax incentives for the mining of REEs and the production of separated rare earth oxides, which NioCorp is considering.

"This bipartisan legislation would provide important tax incentives for the production of permanent rare earth magnets, which, if enacted, could provide powerful incentives for investment across all areas of rare earth production in the U.S., from mining to magnet manufacturing," said Mark A. Smith, CEO of NioCorp. "We are pleased to support this legislation and to work in this alliance to push this bill and other legislative initiatives designed to promote greater production of these and other critical minerals in the U.S."

About NioCorp

NioCorp is developing a superalloy materials project in Southeast Nebraska that will produce Niobium, Scandium, and Titanium. The Company also is evaluating the potential to produce several rare earth byproducts from the Project. 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 is also 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. Magnetic rare earths, such as Neodymium, Praseodymium, Terbium, and Dysprosium are critical to the making of Neodymium-Iron-Boron ("NdFeB") magnets, which are used across a wide variety of defense and civilian applications.
