Conference Call to Be Held Tuesday, February 24, 2015 at 10:30 A.M. EST

TORONTO, ONTARIO--(Marketwired - Feb 23, 2015) - Arena Minerals Inc. ("Arena" or the "Company") (TSX VENTURE:AN) is pleased announce that it has entered into a binding letter agreement with B2Gold Corp. (TSX:BTO) (NYSE:BTG) ("B2Gold"), pursuant to which Arena has granted B2Gold the option to acquire up to a 60% interest in the Pampa Paciencia and Cerro Barco properties (together, the "Property"), which comprise 27,341 hectares of the 149,235 hectare Atacama copper project, located in Antofagasta, Chile (the "Letter Agreement"). In order to exercise the option and acquire a 60% interest in the Property, B2Gold will be required to spend a minimum of US$20.5 million on the Property over a five year period, and make payments of US$630,000 to Sociedad Quimica y Minera de Chile S.A. ("SQM"), the underlying property owner, on behalf of Arena over a three year period. In addition, B2Gold will make payments of US$2.5 million directly to Arena over a three year period as further set out below.

Will Randall, President & CEO of Arena, commented "we are pleased to be partnering with B2Gold on the Cerro Barco and Pampa Paciencia prospects. Not only does this agreement bring a very strong technical team with extensive experience in Chile, it will also meet all of Arena's work commitments for the entire Atacama copper project through to option completion. The total land position to be joint ventured represents approximately 20% of the Atacama land position, giving Arena the flexibility to pursue further transactions on the remaining 80% of the Atacama copper project. This strategy will allow for larger work programs on more aggressive timelines, increasing the potential for value creation while minimizing the dilution to Arena shareholders."

Arena continues to have discussions with several large global mining entities with respect to multiple potential joint venture transactions on various property interests held by Arena.

Arena will host a conference call chaired by Will Randall, the President and CEO in order to update shareholders on the Company's current corporate activities and the Letter Agreement with B2Gold. We invite all shareholders and interested parties to participate in the call. Details for attendance are as follows:

In addition, Arena has granted B2Gold the option to acquire an additional 10% interest in the Property, equal to a 12.5% interest in the special purpose vehicle, by incurring additional exploration expenditures of US$15,000,000 on or prior to August 1, 2020 and funding all expenditures on the Property on behalf of Arena up to and including the completion of a prefeasibility study on the Property (the "Second Option"). Upon satisfaction of the obligations under the Second Option, it is anticipated that B2Gold would hold 75% of the special purpose vehicle and Arena would hold 25%.

B2Gold shall be required to pay the per hectare payments, the exploration and development commitments, annual claim fees and cash payments required on the Property, as set out above, for the period up to and including July 26, 2016.
