NioCorp Developments Ltd. ("NioCorp" or the "Company") is pleased to provide the following report to shareholders on 2014 corporate developments:

In January of 2014, the Company provided guidance for the goals we were looking to achieve in the year ahead.  Commencing in early 2014, we embarked on an aggressive plan to meet those goals.  The plan included continuing to bolster the management team, and raising capital to enable re-start significant field operations and engineering studies to advance the technical knowledge of the Elk Creek Niobium project. 

Many of the specific aspects of this work are highlighted below, but in summarizing what we have achieved through increased technical knowledge of the project and the addition of key personnel, we are proud to recap the positive market response for the year.  In terms of rankings:

- NioCorp was ranked first overall on the TSX Venture Exchange for Market Cap return with an increase of 547% to $97.5 Million at year end (1)
- NioCorp was ranked fourth overall for stock price increase with a 420% increase at year end (2)
- NioCorp was ranked first overall for stock performance following a brokered financing, with a 42% return at year end (3)

These gains in share price and market cap were in stark contrast to the 24.5% drop in the overall TSX Venture Exchange Index during 2014. 

In particular, the Company completed the following accomplishments:

First quarter:
- The Company successfully raised in excess of $3.7 million allowing for a complete review of the historic work on the Elk Creek Niobium project resulting in recommendations for development of this world-class asset.  In pursuit of the recommendations, the Company contracted with SRK Consulting ("SRK") of Lakewood, Colorado, a leading engineering firm, metallurgical firms SGS Canada Inc., of Lakefield, Ontario, and Hazen Research Inc., of Golden, Colorado to advance the project under an aggressive timeline.

Second quarter:
- Metallurgical studies were well underway with two leading metallurgical testing organizations, and drilling operations commenced with West-Core Drilling of Elko, NV as part of a three phase, in-fill drill program designed to enhance the resource category for use in an updated NI43-101 report.  In addition, the drilling program was designed to provide data to support a range of engineering and metallurgical studies of the resource and the project area.
- NioCorp welcomed Scott Honan to the position of Vice President, Business Development to oversee field operations and the technical development of the resource.
- Drilling results were announced from initial drill-holes, increasing confidence in the niobium content of the central portion of the resource.
- Baseline environmental, geotechnical and hydrological studies commenced, in anticipation of future permitting needs. 

Third quarter:
- NioCorp was added to the S&P/TSX Venture Select Index.
- The Company added Mr. Michael Morris, Chairman of the Board of Heritage Oaks Bankcorp and formerly the only independent director of Molycorp, to NioCorp's Board. 
- Mr. Neal Shah, graduate of the University of Colorado's Mechanical Engineering program (BSME) and Purdue University's Krannert School of Management (MBA), with nearly 20 years of experience in various industries, is named to the position of Vice President, Finance.
- Drilling operations continue with West Core, joined by Envirotech Drilling LLC of Winnemucca, NV and Idea Drilling of Virginia, MN, resulting in numerous significant results highlighted as follows:
o NEC14-008 - (NR Aug 11, 2014)
o 12 m (760 - 772 m) at 2.12 % Nb2O5  
       3 m (768-771 m) at 3.23% Nb2O5

      6 m (716.5 - 722.5 m) at 2.47 % Nb2O5
            • 3.5 m (716.5 - 720 m) at 3.09 % Nb2O5 (including individual assay samples in excess of 4.06%)
- September release of an updated NI43-101 resource estimate from the first of three phases of drilling, (Drill Holes NEC14-006 through NEC14-010), reporting an Indicated resource of 28.2 Million Tonnes grading 0.63% Nb2O5, containing 177 Million Kg's of Nb2O5, and an Inferred resource of 132.8 Million Tonnes grading 0.55% Nb2O5, containing 733.7 Million Kg's of Nb2O5, (at a 0.3% Nb2O5 cutoff grade - see NR Sept 22, 2014 for full details). - Mineralogical studies were completed at both Hazen and SGS which demonstrated that 75% to 80% of the Niobium is hosted in the mineral pyrochlore, similar to other producing niobium mines.
- Metallurgical testwork on the resource advanced to the point where a preliminary process flow-sheet was established (NR Aug 5, 2014).
- Highlights of the results from the bench scale Metallurgical tests at SGS in Lakefield, Ontario (see NR September 30, 2014) include:
o Flotation test F55, which demonstrated a niobium recovery of 61% to the flotation concentrate;
o Hydrometallurgical tests (PL13, PL15, PL16, AB13, AB15) of pre-leaching and acid baking process steps that follow flotation demonstrated a combined extraction of nearly 98% of the niobium contained in the flotation concentrate;
o Additional hydrometallurgical tests (Test NbP25) demonstrating the recovery of 98% of the niobium contained in the pre-leach / acid bake products into a precipitate containing 21% Nb by weight.
- A mini-pilot scale flotation test was initiated at SGS Lakefield to scale up the promising bench scale testwork and conduct a long-term continuous test on the performance of the flotation scheme.  The mini-pilot also generated a large quantity of flotation concentrate that was used to support larger scale hydrometallurgical testwork.
