GXII shareholders will receive shares in NioCorp at closing based on a conversion ratio reflecting a post-merger enterprise value of NioCorp estimated at $313.5 million

All amounts are in U.S. dollars, unless indicated otherwise.

CENTENNIAL, Colo., September 26, 2022 — NioCorp Developments Ltd. (“NioCorp” or the “Company“) (TSX: NB; OTCQX: NIOBF) and GX Acquisition Corp. II (“GXII”) (Nasdaq: GXII) today announced the signing of a definitive agreement (the “Business Combination Agreement”) for a proposed business combination between the two companies. Under the Business Combination Agreement, NioCorp will acquire GXII, a U.S.-based special purpose acquisition company, and intends to be listed on the Nasdaq Stock Exchange soon after the acquisition closes, which is expected in the first quarter of 2023.  NioCorp shares will also continue to be traded on the Toronto Stock Exchange (“TSX”).  The proposed Transaction (as defined below) values the combined entity at an estimated enterprise value of $313.5 million.

Assuming no redemptions by GXII public shareholders, upon deal close the combined operating entity could have access to as much as $285 million in net cash (after paying transaction expenses) from the GXII trust account to continue advancing the Elk Creek Critical Minerals Project (the “Elk Creek Project” or the “Project”).  Final proceeds will depend upon redemption rates of current GXII shareholders at the consummation of the proposed Transaction.

Mark A. Smith, CEO and Executive Chairman of NioCorp

Additionally, NioCorp announced the signing of non-binding letters of intent (“LOIs”) for two separate financing packages with Yorkville Advisors Global, LP (“Yorkville”).  Subject to entering into definitive agreements, these financings could provide the Company with access to up to an additional $81 million to help advance the Elk Creek Project.  The financings contemplated by the LOIs include $16 million in convertible debentures that are expected to be funded at the closing of the business combination, and subject to certain limitations can be repaid by NioCorp in either cash or NioCorp common shares, and a standby equity purchase facility pursuant to which NioCorp will have the ability to require Yorkville, subject to the conditions set out in the definitive agreements, to purchase up to $65 million of its common shares.

NioCorp CEO and Executive Chairman Mark A. Smith said:  “This business combination with GXII, and the two additional financing packages, have the potential to significantly accelerate our efforts to obtain the required project financing and to ultimately bring the Elk Creek Project to construction and eventual commercial operation.  Our goal is to rapidly build secure and reliable U.S. supply chains of the critical minerals that multiple industries need to help us build a more sustainable and less carbon-intensive future and for other critical domestic uses.  Once completed, these transactions have the potential to put NioCorp on the fast track to obtain the required project financing to deliver on that promise, and to do so in an environmentally smart manner.”

Dean C. Kehler, Co-Chairman and CEO of GXII said: “NioCorp’s Elk Creek project is the highest-grade niobium deposit under development in North America, and the second largest indicated rare earth resource in the U.S.1  Critical minerals such as niobium and scandium, and magnetic rare earth elements, can accelerate the world’s transition to a lower carbon economy. We believe NioCorp is well-positioned to be a reliable, US-based supplier that will produce these products on a sustainable basis. We are pleased that GXII shareholders will have the opportunity to invest in NioCorp’s Elk Creek Project and help accelerate the transition to a greener world.”

 

NIOCORP’S ELK CREEK PROJECT

Subject to receipt of necessary project financing, NioCorp intends to launch construction of its Elk Creek Project, a pure-play critical minerals project with the highest-grade Niobium resource in N.A. and the second largest indicated rare earth resource in the U.S.3

Located in southeastern Nebraska, the Project is positioned to become a significant U.S. miner and producer of Niobium, Scandium, and Titanium.  Additionally, NioCorp is currently conducting technical and economic analyses of the potential addition to the planned product suite of several magnetic rare earth oxides, which are forecast to experience large supply shortages because of sharply rising demand.4 The Project is located on all private land that NioCorp either owns or has option-to-purchase agreements in place with local landowners to acquire.  NioCorp has secured all federal, state, and local permits necessary to proceed to construction once sufficient project financing is secured. In addition, the Project will be required to obtain a series of permits for operations from federal, state, and local agencies.

The Project has also completed a June 2022 Feasibility Study, as summarized by NioCorp’s 2022 NI 43-101 Elk Creek Technical Report and the NioCorp’s S-K 1300 Elk Creek Technical Report Summary, which shows a $2.8 billion Net Present Value (“NPV”) and a 29.2% Internal Rate of Return (“IRR”), both on a pre-tax basis, and an estimated $403 million in averaged annual EBITDA5 generated.  These figures do not include impacts from the possible addition of magnetic rare earth oxide products to NioCorp’s planned product suite, as NioCorp is currently conducting technical and economic analyses with respect thereto.

The Project also enjoys very strong local support in Nebraska and is projected to create approximately 450 permanent full-time jobs, more than 1,200 contract construction jobs over its 3+ year construction period, and an estimated 2,100 indirect jobs created or supported.  It is also projected to generate $1.1 billion in employee payroll, $298 million in new tax revenue to state and local governmental units, and $148 million in royalty payments to local landowners over the life of the mine.  NioCorp has contracted with the State of Nebraska for tax benefits over the first 10 years of operations that are potentially worth in excess of $200 million.

NioCorp has succeeded in placing 75% of its planned production of ferroniobium over the first 10 years of operations under enforceable sales contracts and has also placed 10% of its planned scandium production under an enforceable sales contract.  The scandium contract is thought to be the largest such commercial sales agreement for scandium ever executed.

The Project also is strongly focused on environmental, social, and governance values and is already aligned with the Equator Principles ESG Framework.

 

BOARD OF DIRECTORS RECOMMENDATIONS

The Business Combination Agreement has been approved by the Board of Directors of each of NioCorp and GXII. Each of the Board of Directors of NioCorp and the Board of Directors of GXII recommends that NioCorp shareholders and GX stockholders, respectively, vote in favor of the business combination.

GenCap Mining Advisory Ltd. has provided a fairness opinion to the Board of Directors of NioCorp stating that, as of the date of such opinion, and based upon and subject to the assumptions, limitations, and qualifications stated in such opinion, the Transaction, defined below, is fair from a financial point of view to NioCorp shareholders.

Scalar LLC has provided a fairness opinion to the Board of Directors of GXII stating that, as of the date of such opinion, and based upon and subject to the assumptions, limitations and qualifications stated in such opinion, the consideration to be received by the holders of GXII’s Class A common stock is fair from a financial point of view to such shareholders.

The directors and management of both NioCorp and GXII have entered into agreements pursuant to which they have committed to vote their respective shares in favor of the business combination.

 

THE NIOCORP-GXII BUSINESS COMBINATION AGREEMENT

Under the terms of the Business Combination Agreement with GXII, GXII will merge with and into a wholly owned subsidiary of NioCorp, with GXII surviving the merger as a subsidiary of NioCorp. NioCorp, as the parent company of the merged entity, will issue common shares to the public shareholders of GXII, with the sponsor shareholders receiving shares in GXII that are exchangeable into common shares of NioCorp. The Business Combination Agreement contemplates that NioCorp will undertake a reverse stock split at the time of close so as to effectuate an expected up-listing to the Nasdaq Stock Market. The transactions contemplated by the Business Combination Agreement and the ancillary agreements thereto are referred to, collectively, as the “Transaction.”

The Business Combination Agreement contains covenants in respect of non-solicitation of alternative acquisition proposals, a right to match any superior proposals for GXII and a termination fee payable to GXII in certain circumstances.

The proposed business combination is expected to close in the first quarter of 2023, subject to effectiveness of the registration statement on Form S-4 that NioCorp expects to file, the satisfaction of customary closing conditions, including certain governmental approvals, the approval of the TSX, and the approval of certain elements of the proposed Transaction by a majority of shareholders of GXII and a majority of NioCorp shareholders voting to approve such elements. The proposed additional financings will also be subject to the approval of the TSX.

Post-closing, the NioCorp Board will include two directors from GXII.

Additional information may be found in the Current Reports on Form 8-K being filed by NioCorp and GXII with the U.S. Securities and Exchange Commission (“SEC”) and the applicable Canadian securities regulatory authorities in connection with the announcement of the proposed Transaction.

NioCorp intends to use the proceeds from the proposed Transaction and the contemplated financings to advance its efforts to launch construction of the Elk Creek Project and move it to commercial operation.

The forward-looking statements are based on the current expectations of the management of NioCorp and GXII, as applicable, and are inherently subject to uncertainties and changes in circumstances and their potential effects and speak only as of the date of such statement. There can be no assurance that future developments will be those that have been anticipated.

Forward-looking statements involve a number of risks, uncertainties or other factors that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those discussed and identified in public filings made by NioCorp and GXII with the SEC and, in the case of NioCorp, with the applicable Canadian securities regulatory authorities and the following: the amount of any redemptions by existing holders of GXII Class A Shares being greater than expected, which may reduce the cash in trust available to NioCorp upon the consummation of the business combination; the occurrence of any event, change or other circumstances that could give rise to the termination of the Business Combination Agreement and/or payment of the termination fees; the outcome of any legal proceedings that may be instituted against NioCorp or GXII following announcement of the Business Combination Agreement and the transactions contemplated therein; the inability to complete the proposed transactions due to, among other things, the failure to obtain NioCorp shareholder approval or GXII shareholder approval or the execution of definitive agreements relating to the convertible debenture transaction and the stand by equity purchase facility contemplated by the term sheets with Yorkville; the risk that the announcement and consummation of the proposed transactions disrupts NioCorp’s current plans; the ability to recognize the anticipated benefits of the proposed transactions; unexpected costs related to the proposed transactions; the risks that the consummation of the proposed transactions is substantially delayed or does not occur, including prior to the date on which GXII is required to liquidate under the terms of its charter documents; NioCorp’s ability to operate as a going concern; NioCorp’s requirement of significant additional capital; NioCorp’s limited operating history; NioCorp’s history of losses; cost increases for NioCorp’s exploration and, if warranted, development projects; a disruption in, or failure of, NioCorp’s information technology systems, including those related to cybersecurity; equipment and supply shortages; current and future offtake agreements, joint ventures, and partnerships; NioCorp’s ability to attract qualified management; the effects of the COVID-19 pandemic or other global health crises on NioCorp’s business plans, financial condition and liquidity; estimates of mineral resources and reserves; mineral exploration and production activities; feasibility study results; changes in demand for and price of commodities (such as fuel and electricity) and currencies; changes or disruptions in the securities markets; legislative, political or economic developments; the need to obtain permits and comply with laws and regulations and other regulatory requirements; the possibility that actual results of work may differ from projections/expectations or may not realize the perceived potential of NioCorp’s projects; risks of accidents, equipment breakdowns, and labor disputes or other unanticipated difficulties or interruptions; the possibility of cost overruns or unanticipated expenses in development programs; operating or technical difficulties in connection with exploration, mining, or development activities; the speculative nature of mineral exploration and development, including the risks of diminishing quantities of grades of reserves and resources; claims on the title to NioCorp’s properties; potential future litigation; and NioCorp’s lack of insurance covering all of NioCorp’s operations.

Should one or more of these risks or uncertainties materialize or should any of the assumptions made by the management of NioCorp and GXII prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements.

All subsequent written and oral forward-looking statements concerning the proposed Transaction or other matters addressed herein and attributable to NioCorp, GXII or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to herein. Except to the extent required by applicable law or regulation, NioCorp and GXII undertake no obligation to update these forward-looking statements to reflect events or circumstances after the date hereof to reflect the occurrence of unanticipated events.


Mineral Reserves and Resources

Unless otherwise indicated, information concerning NioCorp’s mining property included in this press release has been prepared in accordance with the requirements of National Instrument 43-101 – Standards of Disclosure for Mineral Projects” (“NI 43-101”) and the Canadian Institute of Mining and Metallurgy (“CIM”) “Definition Standards – For Mineral Resources and Mineral Reserves, May 10, 2014” (the “CIM Definition Standards”). Beginning with NioCorp’s Annual Report on Form 10-K for the fiscal year ended June 30, 2022 (the “NioCorp Form 10-K”), NioCorp’s mining property disclosures included or incorporated by reference in its SEC filings are required to be prepared in accordance with the requirements of subpart 1300 of Regulation S-K (“S-K 1300”). Previously, NioCorp prepared its estimates of mineral resources and mineral reserves following only NI 43-101 and the CIM Definition Standards. On June 28, 2022, NioCorp issued a CIM-compliant NI 43-101 technical report (the “2022 NI 43-101 Elk Creek Technical Report”) for the Elk Creek Project, which is available through the website maintained by the Canadian Securities Administrators at www.sedar.com. On September 6, 2022, the Company filed a technical report summary for the Elk Creek Project that conforms to S-K 1300 reporting standards (the “S-K 1300 Elk Creek Technical Report Summary”) as Exhibit 96.1 to the NioCorp Form 10-K, which is available through the website maintained by the SEC at www.sec.gov. The 2022 NI 43-101 Elk Creek Technical Report and S-K 1300 Elk Creek Technical Report Summary are based on a feasibility study (the “June 2022 Feasibility Study”) prepared by qualified persons (within the meaning of both NI 43-101 and S-K 1300, as applicable) and are substantively identical to one another except for internal references to the regulations under which the report is made, and certain organizational differences. The requirements and standards under Canadian securities laws, however, differ from those under S-K 1300. The terms “mineral resource,” “indicated mineral resource” and “mineral reserve” included herein are used as defined in accordance with NI 43-101 under the CIM Definition Standards. While the terms are substantially similar to the same terms defined under S-K 1300, there are differences in the definitions. Accordingly, there is no assurance any mineral resource or mineral reserve estimates that the Company may report under NI 43-101 will be the same as the mineral resource or mineral reserve estimates that the Company may report under S-K 1300.

NioCorp discloses estimates of both its mineral resources and mineral reserves. You are cautioned that mineral resources are subject to further exploration and development and are subject to additional risks and no assurance can be given that they will eventually convert to future reserves. Under both regimes, inferred resources, in particular, have a great amount of uncertainty as to their existence and their economic and legal feasibility. Investors are cautioned not to assume that any part or all of the inferred resource exists or is economically or legally mineable. See Item 1A, Risk Factors in the NioCorp Form 10-K. Reference should be made to the full text of the 2022 NI 43-101 Elk Creek Technical Report and the S-K 1300 Elk Creek Technical Report Summary for further information regarding the assumptions, qualifications and procedures relating to the estimates of mineral reserves and mineral resources as defined under NI 43-101 and S-K 1300, respectively.


Qualified Persons

All technical and scientific information included in this press release derived from the June 2022 Feasibility Study respecting NioCorp’s mineral resources has been reviewed and approved by Matthew Batty, P.Geo., Owner, Understood Mineral Resources Ltd., and all such information respecting NioCorp’s mineral reserves has been reviewed and approved by Richard Jundis, P. Eng., Director of Mining, Optimize Group.  Each of Mr. Batty and Mr. Jundis and their respective firms are independent consultants who provide consulting services to NioCorp.  All other technical and scientific information included in this press release has been reviewed and approved by Scott Honan, M.Sc., SME-RM, NioCorp’s Chief Operating Officer.  Each of Messrs. Batty, Jundis, and Honan is a “Qualified Person” as such term is defined in NI 43-101.


Financial Information; Non-GAAP Measures

Certain financial information and data included in this press release is unaudited and may not conform to Regulation S-X. Such information and data may not be included in, may be adjusted in or may be presented differently in the registration statement to be filed relating to the proposed Transaction and the joint proxy statement/prospectus contained therein. This press release also includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”), including, but not limited to, “Averaged EBITDA,” “Averaged EBITDA Margin,” and “After-Tax Cumulative Net Free Cash Flow.” These performance measures do not have a standard meaning within GAAP and, therefore, amounts presented may not be comparable to similar data presented by other companies. These non-GAAP financial measures, and other measures that are calculated using these non-GAAP measures, are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing NioCorp’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. These non-GAAP financial measures are included in this press release because they are key performance measures used in the June 2022 Feasibility Study for purposes of projecting the economic results of the Elk Creek Project, and NioCorp and GXII believe that these non-GAAP measures provide useful information to management and investors regarding certain financial and business trends relating to NioCorp’s financial condition and results of operations. NioCorp and GXII believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing NioCorp’s financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures.

The non-GAAP financial measures included in this press release are projections. Reconciliations of these forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures are not provided because NioCorp is unable to provide such reconciliations without unreasonable effort, due to the uncertainty and inherent difficulty of predicting the occurrence and the financial impact of such items impacting comparability and the periods in which such items may be recognized. For the same reasons, the Company is unable to address the probable significance of the unavailable information, which could be material to future results. See “Forward-Looking Statements.”

In addition to the non-GAAP financial measures, this press release may contain financial forecasts and projections (collectively, “prospective financial information”) of NioCorp. Neither the independent registered public accounting firm of NioCorp nor the independent registered public accounting firm of GXII audited, reviewed, compiled or performed any procedures with respect to the prospective financial information for the purpose of their inclusion in this press release, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this press release. This prospective financial information constitutes forward-looking statements and should not be relied upon as being guarantees or necessarily indicative of future results. The assumptions and estimates underlying such prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. See “Forward-Looking Statements.” Accordingly, there can be no assurance that the prospective financial information is indicative of future performance of NioCorp or that actual results will not differ materially from the results presented in the prospective financial information included in this press release. Actual results may differ materially from the results contemplated by the prospective financial information included in this press release. The inclusion of such prospective financial information herein should not be regarded as a representation by any person that the results reflected in such projections will be achieved.

The purpose of the prospective financial information is to assist investors, shareholders and others in evaluating the performance of NioCorp’s business. The prospective financial information may not be appropriate for other purposes. Information about NioCorp’s guidance, including the various assumptions underlying it, is forward-looking and should be read in conjunction with “Forward-Looking Statements” in this press release, and the related disclosure and information about various economic, competitive, and regulatory assumptions, factors, and risks that may cause NioCorp’s actual future financial and operating results to differ from what NioCorp currently expects.
