More than 150 investors toured the Elk Creek Superalloy Materials Project (the "Project") site in southeast Nebraska last week, hosted by project owner NioCorp Developments ("NioCorp" or the "Company") (TSX: NB;OTCQX: NIOBF).

Shareholders were provided with tours of land recently purchased by NioCorp, near Elk Creek, Nebraska, where much of the Company's proposed Project will be located.  The Project incorporates a proposed underground mine and surface processing facilities for the production of niobium, scandium, and titanium, once project financing is obtained.  The Company also is evaluating the potential to produce several rare earth elements as byproducts.

Senior NioCorp executives, including CEO and Chairman Mark A. Smith, COO Scott Honan, CFO Neal Shah, VP of External Affairs Jim Sims, and Corporate Controller Jeff Mason were on hand to conduct the tours and briefings for shareholders.

"On behalf of the entire NioCorp team, I want to thank all of our shareholders who came out to tour the Elk Creek Project site last week and I want to thank everyone for their continuing interest in this Project," said Mr. Smith.  It is not an easy process to bring projects of this size and scope into commercial operation, but we are continuing to make progress every single week to move this project to reality."

About NioCorp

NioCorp is developing a superalloy materials project in Southeast Nebraska that will produce Niobium, Scandium, and Titanium.  The Company also is evaluating the potential to produce several rare earth byproducts from the Project.  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 is also 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.  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.
