VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec 31, 2014) - NioCorp Developments Ltd. ("NioCorp" or the "Company") (TSX VENTURE:NB)(OTCQX:NIOBF)(FRANKFURT:BR3) has filed amended condensed consolidated interim financial statements and notes for the three months ended September 30, 2014 (the "Amended Interim Financials") to reflect the correction of an error in the Company's original condensed consolidated interim financials for the three months ended September 30, 2014 filed on SEDAR on November 26, 2014.

The financial statements as initially prepared have been amended to correct an error in the condensed consolidated interim statements of cash flows. Specifically the deferred exploration costs have been adjusted to reflect the actual cash expended and the resulting difference that affects the change in non-cash working capital items - accounts payable and accrued liabilities. There is no impact on the statement of financial position or the statement of comprehensive loss. The effect of the error is more fully disclosed in Note 2 to the Amended Interim Financials.
