B2Gold to Spend an Additional $6.0 Million to Earn a 70% Interest in Calibre's Primavera Gold-Copper Project and Surrounding Borosi Concessions in the Mining Triangle, Nicaragua

Vancouver, British Columbia: Calibre Mining Corp. (TSX-V: CXB) (the "Company" or "Calibre") is pleased to announce that the Company has signed a definitive Joint Venture Agreement (the "JV Agreement") with B2Gold Corp. ("B2Gold") granting B2Gold an option to acquire a further 19% interest in and to the Primavera Gold-Copper Porphyry Project containing a total of 322 km2 of mineral concessions (together, the "Project") in north-east Nicaragua. Calibre currently controls a 49% interest in the Project, while B2Gold controls a 51% interest and is project operator. In addition to this joint venture with B2Gold, Calibre controls a 100% interest in 463 km2 of mineral concessions in the Mining Triangle of northeast Nicaragua which includes the recent, high-grade gold discovery at the Montes de Oro Project.

The JV Agreement dated September 9, 2013 allows B2Gold to earn an additional 19% interest in and to the Project for a total interest of 70% by spending $6.0 million in additional project expenditures over 36 months (3 years). The JV Agreement supersedes and replaces the original Option Agreement between Calibre and B2Gold (entered into in June 2009 and amended in July 2010 and October 2010) which has now been terminated.

Greg Smith, President and CEO stated, "The signing of the Joint Venture Agreement with B2Gold is an important step forward for the Primavera Gold-Copper Porphyry Project. As previously announced, B2Gold has initiated a $2.0 million program on the Primavera Project to expand the existing high grade gold-copper mineralized zone and to locate additional gold and copper discoveries within the 322 km2 Borosi mineral concessions. We are very pleased to have B2Gold as Calibre's partner in the Primavera gold-copper discovery and look forward to significantly advancing the Project under the JV Agreement."

  • Calibre has granted B2Gold an option (the "Option") to acquire an additional 19% interest in and to the Project for a total interest of 70% in the Project by incurring CDN$6,000,000 in additional exploration and development expenditures on the Property over 36 months (3 years). Each (12 months) of the Option B2Gold must incur a minimum of $1.5 million of exploration and development expenditures on the Property. Expenditures incurred by any date in excess of the aggregate amount of expenditures required to be incurred by such date shall be carried forward to the succeeding period or periods and qualify as expenditures for such succeeding period or periods.
  • Upon the exercise of the Option by B2Gold, B2Gold and Calibre shall share all further exploration and development expenditures on the Property on a 70% (B2Gold)/30% (Calibre) basis. B2Gold will be project operator.
