NioCorp Demonstrates Higher Niobium Recovery Rates
New Processing Approach Demonstrates the Ability to Make More Niobium per Tonne of Ore, Produce a Higher Purity Product, and Potentially Address New Markets with Different Niobium Products
CENTENNIAL, May 25, 2023 - NioCorp Developments Ltd. ("NioCorp" or the "Company") (NASDAQ:NB)(TSX:NB) is pleased to announce that it has successfully demonstrated the ability to recover greater amounts of the critical mineral niobium from each tonne of ore the Company expects to mine at its Elk Creek Critical Minerals Project, located in southeast Nebraska, once sufficient financing is obtained and the project is constructed.
Final results from NioCorp's metallurgical demonstration plant in Trois Rivieres, Quebec, show that NioCorp's new and improved recovery process can achieve a 90.7% rate of niobium recovery through the hydrometallurgical process. Overall recovery through the pyrometallurgical production of the commercial product ferroniobium is expected to be 86.7%. NioCorp's previous approach to niobium production was able to achieve recovery rates through the hydrometallurgical and pyrometallurtical processes of 86.8% and 82.4%, respectively.
The higher rates of niobium recovery from NioCorp's new process point to the likelihood of higher niobium production levels from NioCorp from the same mining tonnage, although a final determination of planned niobium production can be made only after work related to a mineral reserve update, additional engineering, updated project capital and operating cost estimates, and other required information is produced for publication in a new Feasibility Study.
Potential New Forms of Niobium Products and Potential Markets
NioCorp's new process approach, which incorporates a chlorination step to improve niobium and titanium separation and purification, also has demonstrated NioCorp's ability to potentially produce three different niobium products: (1) ferroniobium; (2) niobium chloride; and (3) niobium oxide.
- NioCorp had previously planned to make ferroniobium, which is used by the steel industry to produce high-strength low-alloy steel alloys. Those alloys are used in the construction, automotive and transport, aerospace and defense, oil and gas, and other industries. Niobium is a $3.3 billion per year global market but is currently served by only three major niobium producers in two countries.
- Niobium chloride would likely be converted by NioCorp into niobium oxide, but niobium chloride is also used in glass and ceramic manufacturing.
- Niobium oxide is critical to multiple applications, including niobium-lithium-ion batteries, superalloys, superconducting applications, capacitors, specialized optics, and many others. Its use in niobium-lithium-ion batteries is considered by current niobium producers as one of the fastest-growing prospective global niobium markets.
More Streamlined Production Process Demonstrated
NioCorp's new process has been demonstrated to be more efficient than the previous design, is expected to require fewer processing steps, and may allow the elimination of entire processes in NioCorp's planned processing plant in Nebraska, such as acid regeneration.
"I am very pleased with the results shown in our demonstration plant for niobium recovery," said Mark A. Smith, CEO and Executive Chairman of NioCorp. "These results point strongly to the likelihood of NioCorp producing more niobium from each tonne of Elk Creek Project ore, which could have positive impacts on our Project's anticipated overall financial returns. These results also point to the prospect of our Project producing more forms of niobium for a greater range of global markets."
"These are very exciting results and they point to potentially greater production levels and additional optionality in terms of where we can sell niobium and the prices these products command," said Scott Honan, NioCorp Chief Operating Officer. "While the demonstration plant has performed well, the pace of operations has gone at a slower rate than any of us would have liked. That is often the case with demonstration plants, which by their nature are designed to investigate innovate pathways for producing commercial products as well as stress testing those processes. Our top priority in this project has always been to maintain a very high standard for technical feasibility and testing, and to conduct the work safely and efficiently. Adhering to high standards is critical to the project's success, including being able to attract necessary financing to bring projects such as ours to commercial reality."

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.
