NioCorp Developments Provides Metallurgical Testing Update

NioCorp Developments (TSXV:NB,OTCQX:NIOBF,FWB:BR3) provided an update on metallurgical testing for ore from its Elk Creek deposit in Nebraska. The company has completed some of the bench scale testing for the program, and has also completed a preliminary metallurgical flowsheet for the project.

As quoted in the press release:

Highlights of the results from the bench scale tests at SGS in Lakefield, Ontario include:

• Flotation test F55, which demonstrated a niobium recovery of 61% to the flotation concentrate;
• Hydrometallurgical tests (PL13, PL15, PL16, AB13, AB15) of pre-leaching and acid baking on the flotation concentrate, demonstrating a combined extraction of 98% of the niobium contained in the flotation concentrate;
• Additional hydrometallurigcal 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.

NioCorp CEO, Mark A. Smith, said:

The metallurgical program has advanced quickly since April, and has delivered high metallurgical recoveries across the process steps that have been tested to date. We look forward to moving quickly through the balance of the metallurgical test program as we continue to de-risk the project through increased technical knowledge of this world-class deposit.
