Elimination of Railroad Spur Line to NioCorp´s Elk Creek Project is Expected to Simplify U.S. Army Corps of Engineers Permit Process by Reducing Environmental Impacts

CENTENNIAL, Jan. 24, 2017 - Recent metallurgical process breakthroughs allowing the recycling of materials previously planned for disposal as part of the Elk Creek Superalloy Project (the “Project”) by NioCorp Developments Ltd. (“NioCorp” or the "Company”) (TSX:NB) (OTCQX:NIOBF) (FSE:BR3) should simplify and streamline the Project’s permitting by the U.S. Army Corp of Engineers (“USACE”) because of significantly reduced environmental impacts.

The Company’s October 2015 Preliminary Economic Assessment (“Oct. 2015 PEA”) of the Project called for a seven-kilometer railroad spur line, along with supporting rail infrastructure, in order to deliver approximately 7,000 tonnes per week of reagents needed for separation and purification of the three superalloy metals (Niobium, Scandium, and Titanium) that NioCorp plans to produce.

Metallurgical process advances announced last week by NioCorp (news release of Jan. 18, 2017) will allow the Project to recycle many of these reagents from material that previously was planned for disposal either in an on-site tailings storage area or as mine backfill. They also will allow an elimination of the planned railroad spur line and supporting infrastructure. That, in turn, will dramatically reduce the Project’s projected impacts on federally regulated waterways that are subject to regulation by the USACE.

The original railroad spur line would have required constructing several railroad bridges over the Nemaha River, Elk Creek, and various tributaries, as well as impacting an estimated 2.6 acres of wetlands and open water, and more than 1,700 feet of various water channels. With those proposed impacts now removed, the Project’s “Section 404” permit should be considerably less complicated and the associated environmental review process able to be conducted more efficiently.

“As we continue to shrink the overall environmental footprint of our Elk Creek Project, the elimination of a rail spur line is a major advance, both environmentally and economically,” said Mark A. Smith, CEO and Executive Chairman of NioCorp. “The largest single set of potential impacts to federally regulated waters was presented by the construction of the rail line over a number of water features. Given that we have found a way to remove these impacts from our Section 404 permit by recycling more material on-site, this presents a very good outcome both for the Project and for the environment. It also represents another major de-risking for the Project.”

Other benefits from the removal of the railroad spur line and supporting rail infrastructure include the elimination of new rail crossings in the vicinity of the project as well as the elimination of the need to acquire rights to additional land on which the spur line and supporting infrastructure would prospectively have been located.

NioCorp’s recently announced metallurgical and process breakthroughs also are expected to help reduce the volume of material planned for disposal in the Project’s tailings storage area, as more of this material is expected to be recycled, which further reduces the environmental footprint of the Project.

NioCorp’s Oct. 2015 PEA included a capital cost (CAPEX) estimate of $21.3 million for the rail and supporting rail infrastructure, including a 24% contingency. NioCorp understands that those costs will now be removed from the Project’s Feasibility Study. Final CAPEX estimates for the Project will be determined when all remaining Feasibility Study work is complete.

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.
