NioCorp Files NI 43-101 Technical Report on its 2022 Elk Creek Critical Minerals Project Feasibility Study
Previously announced updated feasibility study confirms that the Elk Creek Project has the second largest indicated-or-better rare earth resource in the U.S., second only to MP Materials' Mountain Pass deposit
CENTENNIAL, June 29, 2022 - NioCorp Developments Ltd. ("NioCorp" or the "Company") (TSX: NB; OTCQX: NIOBF) is pleased to announce that it has filed a Technical Report (the "Report") prepared in accordance with National Instrument 43-101 ("NI 43-101") regarding its previously announced 2022 Feasibility Study ("2022 FS") completed for the Company's Elk Creek Critical Minerals Project (the "Project").
According to the 2022 FS, in addition to niobium, scandium, and titanium, the Elk Creek Mineral Resource contains various amounts of all rare earth elements ("REEs"). There is potential for NioCorp's REEs to be mined, crushed, and placed into solution as part of the process NioCorp plans to use to produce its primary niobium, scandium, and titanium products, once Project financing is secured.
Depending upon the outcome of metallurgical testing on REE recovery rates from Elk Creek ore, soon to be launched at a demonstration plant in Quebec, and on whether necessary Project financing is secured, NioCorp could produce separated rare earths as a byproduct, placing it at a competitive advantage vis-à-vis other rare earth projects.
The 2022 FS was done in collaboration with Understood Mineral Resources Ltd., Optimize Group Inc., and Dahrouge Geological Consulting Ltd. It includes an updated Mineral Resource that shows that the Project has the second largest indicated-or-better rare earth resource in the U.S., second only to MP Materials' Mountain Pass deposit in California. REEs were evaluated as a potential by-product to the mining of niobium, titanium, and scandium; thus the estimated values of the REEs are reported using the previously determined diluted Net Smelter Return as derived from the Nb2O5, TiO2, and scandium Mineral Resources.
"If our testing continues to show the positive results we have seen to date, and we decide to add magnetic rare earths to our potential product line, the Elk Creek Project will represent a unique critical minerals project after project financing is obtained and the Project is put into commercial operation," said Mark A. Smith, CEO and Executive Chairman of NioCorp. "We believe the minerals we intend to produce in America's heartland are essential to the world's accelerating energy transition and to the many technologies that will make it possible, including those in electrified transportation, renewable energy, infrastructure projects, and many others."
"I want to thank the members of our technical team and the group of independent experts who helped to make this feasibility study possible," said Scott Honan.
The 659 page Report supports the Company's May 19, 2022 news release that provided results of the 2022 FS. The Report can be seen on SEDAR and on the Company's website at https://www.niocorp.com/wp-content/uploads/NioCorp_June-2022_NI_43-101_Technical_Report.pdf.
Rare Earths in the Elk Creek Mineral Resource
The 2022 FS shows that the Elk Creek Project contains an estimated 632.9 kilotonnes ("kt") of contained total rare earth oxides ("TREO") in the indicated mineral resource category.1 According to U.S. Geological Survey data,2 this places the Elk Creek Mineral Resource behind MP Materials' Mountain Pass deposit but ahead of all other current rare earth projects in the U.S. in terms of contained TREO from a NI 43-101 rare earth resource of indicated or higher classification.
The Elk Creek Indicated Mineral Resource includes the following tonnages of contained metals, using a ?US$180/tonne NSR cut-off that was calculated using solely the contained niobium, scandium, and titanium in the Mineral Resource:
- 632.9 kt of TREO, including these individual rare earth oxides:
- 26.9 kt of praseodymium
- 98.9 kt of neodymium
- 2.3 kt of terbium
- 9.1 kt of dysprosium
- 970.3 kt of niobium oxide
- 11,337 tonnes ("t") of scandium oxide
- 4,221 kt of titanium oxide
As shown in Table 1 below, the 2022 FS shows that expected Pre-Tax and After-Tax Net Present Value ("NPV") of the Project both increased, the mine's expected life has been extended from 36 to 38 years, and expected Life of Mine ("LOM")3 gross revenue for all three currently planned products (niobium, scandium, and titanium) have increased. The economic analysis was conducted on the same basis as the Company's 2019 Feasibility Study, using 2019 costs and product pricing.

Next Steps in NioCorp's Plans to Add Rare Earths to the Project
Of the REEs shown by the 2022 FS to be contained in the Elk Creek Mineral Resource, NioCorp is presently focusing on the magnetic REE products neodymium-praseodymium oxide, dysprosium oxide, and terbium oxide at purity levels that meet current commercial requirements. There currently is no commercial-scale production in North America of these separated rare earth products from ore mined in the U.S.
NioCorp plans to issue a further updated NI 43-101 technical report that will detail the Company's plans for possibly producing rare earth products and will determine the net impact of integrating rare earth operations into the Project.

End Notes
Non-GAAP Financial Measures
This news release includes certain forward-looking non-GAAP financial measures, including EBITDA. These non-GAAP financial measures are included in this news release because these statistics are key performance measures that management uses to monitor performance, to assess how the Company is performing, to plan and to assess the overall effectiveness and efficiency of operations. 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 mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with GAAP. Reconciliations of these forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures are not provided because the Company 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.
SEC Standards Regarding Mineral Resources and Reserves
Estimates of mineralization and other technical information included or referenced in this news release have been prepared in accordance with NI 43-101. The definitions of proven and probable mineral reserves used in NI 43-101 differ from the definitions in U.S. Securities and Exchange Commission ("SEC") Industry Guide 7. Under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. As a result, the reserves reported by the Company in accordance with NI 43-101 may not qualify as "reserves" under SEC Industry Guide 7 standards. In addition, the terms "mineral resource," "measured mineral resource," "indicated mineral resource," and "inferred mineral resource" are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the SEC. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian securities laws, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Additionally, the disclosure of "contained pounds" in a resource is permitted disclosure under Canadian securities laws; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measurements. Accordingly, information contained or referenced in this news release containing descriptions of the Company's mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of United States federal securities laws and the rules and regulations thereunder.
Additionally, in October 2018, the SEC approved final rules requiring comprehensive and detailed disclosure requirements for issuers with material mining operations. The provisions in Industry Guide 7 and Item 102 of Regulation S-K have been replaced with a new subpart 1300 of Regulation S-K ("S-K 1300")under the Securities Act of 1933. The Company will be required to comply with these new rules in its disclosures for the fiscal year ending June 30, 2022, and thereafter. The requirements and standards under S-K 1300 differ from those under Canadian securities laws. The terms "mineral resource," "inferred mineral resource," "indicated mineral resource," "mineral reserve," "probable mineral reserve," and "proven mineral reserve" used in this news release are mining terms as defined in accordance with NI 43-101 under guidelines set out in the Definition Standards for Mineral Resources and Mineral Reserves adopted by the Canadian Institute of Mining, Metallurgy and Petroleum Council. 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 resources or mineral reserves that the Company may report under NI 43-101 will be the same as resource or reserve estimates prepared under the standards adopted under S-K 1300.
