NioCorp Shares Expected to Begin Trading on Tuesday on Nasdaq Under the Ticker Symbol "NB" and Will be Cross-Listed on the Toronto Stock Exchange

CENTENNIAL, Colo., March 16, 2023 /PRNewswire/ -- NioCorp Developments Ltd. ("NioCorp" or the "Company") (TSX: NB) (OTCQX: NIOBF) is pleased to announce that it expects to have access to as much as $71.9 million in net proceeds over the next three years following the completion of the transactions contemplated by the Business Combination Agreement, dated September 25, 2022 (the "Business Combination Agreement"), among NioCorp, GX Acquisition Corp. II (Nasdaq: GXII) ("GX") and Big Red Merger Sub Ltd (the "Transaction"), and two separate financing deals with Yorkville Advisors Global, LP ("Yorkville"). 

The Transaction was approved by a vote of GXII shareholders on Wednesday, March 15, 2023, and the deal is expected to close on Friday, March 17, 2023.  NioCorp's common shares (the "Common Shares") are expected to begin trading on Tuesday, March 21, 2023, on the Nasdaq Stock Market ("Nasdaq") under the ticker symbol "NB."  The Nasdaq listing is expected to make investment in NioCorp's stock open to many more investors around the world, including institutional investors and funds.  Upon listing on Nasdaq, the Common Shares will be cross-listed on the Toronto Stock Exchange and will continue to trade there under the ticker symbol "NB." The stock will no longer trade on the OTCQX under the ticker symbol "NIOBF" in connection with the commencement of trading on Nasdaq.

In connection with closing, NioCorp expects to receive approximately $15.28 million in gross proceeds from the Transaction.  Deal costs are anticipated to be approximately $20.3 million.  NioCorp expects to receive an additional $15.36 million in net proceeds from a separate convertible debt financing with Yorkville (the "Yorkville Convertible Debt Financing"), and also expects to have access to up to an additional $61.6 million in net proceeds from a standby equity facility with Yorkville (together with the Yorkville Convertible Debt Financing, the "Yorkville Financings") over the next three years, following the expected close of those transactions on Friday.  Total expected net proceeds from the Transaction and the Yorkville Financings are expected to be $71.9 million over the next three years.

"This transaction with GXII delivered to us several important benefits, including a ready pathway to an up-listing to the Nasdaq Stock Market, which is expected to allow additional institutional firms to invest in and trade in our stock for the first time.  Further, it has given NioCorp and the Elk Creek Project a much higher profile among institutional investors looking for promising projects in the critical materials space," said Mark A. Smith, CEO and Executive Chairman of NioCorp.

"While all of us would rather have seen higher proceeds from the GXII transaction, the cash infusion resulting from this deal, along with our financings with Yorkville, is expected allow us to continue to move the Elk Creek Project forward," said Mr. Smith.  "This Project is a strategically vital one for the United States, and we intend to continue to move it forward to full financing and a construction start as rapidly as possible."

Mr. Smith added:  "NioCorp's Elk Creek Project is clearly on the U.S. Government's radar screen now, as evidenced by the non-binding Letter of Interest for up to $800 million we recently received from the Export-Import Bank of the United States.  Government assistance is particularly vital to projects such as ours that face government-subsidized competitors in foreign nations such as China and the uneven playing field this creates.  It also is necessary given that obtaining financing from commercial debt markets for long-lead projects such as greenfield critical minerals mines can be challenging."

Dean Kehler, Co-Chairman and CEO of GXII, said:  "Many new investors, including institutional and other large investment funds, are now expected to look more closely at NioCorp, particularly since the Company's stock is expected to begin trading on Nasdaq.  In my experience, even in volatile markets, hard assets that are expected to be strategic, long-lived, and valuable -- such as the Elk Creek Project – are able to attract the capital necessary to unlock their value, both for investors and for the economic and national security of the United States."

NioCorp's Elk Creek Critical Minerals Project is expected to produce niobium, scandium, and titanium – all of which have been designated as critical minerals by the U.S. Government. The US is currently 100% dependent upon foreign producers for niobium and scandium and is more than 90% dependent on foreign sources for titanium mineral concentrate.  NioCorp is currently examining the technical feasibility of separating high-purity oxides of the magnetic rare earths (1) neodymium-praseodymium oxide ("NdPr"), which is the principal component of neodymium-iron-boron ("NdFeB") permanent rare earth magnets; (2) dysprosium oxide ("Dy"); and (3) terbium oxide ("Tb").  In addition to NdPr, both Dy and Tb oxide are critical to the type of powerful NdFeB magnets used in the traction motors of electric vehicles.  However, very little of these high-purity separated rare earth products are made outside of Asia.

The Transaction and the Yorkville Financings are subject to a number of closing conditions and there is no guarantee that they will close on the terms described herein, if at all.

About NioCorp

NioCorp is developing a critical minerals project in Southeast Nebraska that will produce niobium, scandium, and titanium.  The Company also is evaluating the potential to produce several rare earths from the Project.  Niobium is used to produce specialty alloys 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 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 ("NdFeB") magnets, which are used across a wide variety of defense and civilian applications.
