CENTENNIAL, Colo. (July 25, 2019) – NioCorp Developments Ltd. (“NioCorp” or the “Company“) (TSX: NB; OTCQX: NIOBF) is pleased to announce it has submitted a State Construction Air Permit application for its Elk Creek Superalloy Materials Project (the “Project”) with the Nebraska Department of Environmental and Energy (“NDEE”).

The permit review process will be led by NDEE personnel.  The advanced emissions control technologies included as part of the planned Project are expected to result in prospective air emissions that are below levels that trigger the need for a permit under the Prevention of Significant Deterioration (“PSD”) program.  As a result, the Project is expected to be able to navigate a more efficient permitting process than is typically encountered under the PSD process.

The Nebraska Department of Environment and Energy allows for applicants to request a variance under state law to allow construction to start before a final state air quality construction permit is issued.  A variance request would only be pursued if issuance of the construction permit extends past the time where the construction of permanent Project features is expected to take place.  Once project financing is obtained and on-the-ground activity commences at the Project site, the Company can proceed without the air quality construction permit or a permit variance to conduct months of earthwork related to site preparation, land grading and clearing, drilling, geotechnical examination, equipment mobilization, temporary worker support infrastructure, off-site electrical and natural gas supply development, and other earthwork-related activities that are not directly associated with permanent Project features.

The Project’s relatively low planned emissions profile resulted from NioCorp’s early efforts to recycle process reagents and its plans to deploy various emissions control technologies, such as baghouses, scrubbers, low nitrogen oxide (NOx) combustion systems, state-of-the-art acid regeneration, and other technologies.

Mark Smith, CEO and Executive Chairman of NioCorp, said:  “I’m very pleased that the NioCorp team has achieved this significant milestone toward enabling a construction start of the Elk Creek Project.  The company’s commitment to reducing the Project’s expected environmental impacts has already delivered tangible benefits, as evidenced by the more efficient air quality permitting process that we can now pursue.  This underscores, once again, that doing right by the environment can also be good for business.”

About NioCorp

NioCorp is developing a superalloy materials project in Southeast Nebraska that will produce Niobium, Scandium, and Titanium. 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 also is 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.
