Calibre Mining and B2Gold Continue Exploration on Borosi Joint Venture, Nicaragua

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Oct. 8, 2015) - Calibre Mining Corp. (TSX VENTURE:CXB) (the "Company" or "Calibre") is pleased to provide an update as the Company and B2Gold Corp. ("B2Gold") (TSX:BTO)(NYSE MKT:BTG) continue to advance the Joint Venture on the Borosi Concessions, Northeast Nicaragua.

B2Gold previously earned a 51% interest in the 208.8 km2 project area by spending $8 million. Calibre controls a 49.0% interest in the joint venture and B2Gold has a 51.0% interest and is project operator. B2Gold has the right to earn an additional 19.0% in the Borosi concessions joint venture by spending $6.0 million in additional project expenditures by April 2016.

Highlights

  • Current field work is focused on the Monte Carmelo Gold Project, which is located north of the town of Rosita, where geological mapping and geochemical sampling has outlined skarn and structurally-related gold mineralization with results to date up to 16.90 g/t Au in rocks and up to 8.07 g/t Au in rock-soils.
  • Recent mapping has extended the main skarn body 180 m to the northwest and 50 m to the southwest with the overall size of the main skarn body now >700 m by 200-300 m.
  • During August 2015 exploration at the Monte Carmelo Gold Project consisted of the collection of 147 auger samples ("rock-soils") and 15 surface rock samples. During 2015 a total of 866 rock-soil and 488 rock samples have been collected within the Joint Venture area over various targets
  • The Joint Venture also hosts the Primavera Gold-Copper Porphyry Project and the Minnesota Gold Project
  • Additional exploration including mapping as well as surface and auger sampling is on-going and is designed to expand and further define the Monte Carmelo Target

President and CEO, Greg Smith stated: "B2Gold continues to be very active in the field and has again been successful identifying and advancing a potential bulk tonnage near surface gold target on the Joint Venture concessions. The Monte Carmelo Target is in the heart of this historic mining camp, however previous work was largely focused on outlining iron mineralization and the current program is the first to systematically evaluate the gold potential. The Monte Carmelo Project is located north of the historic mining town of Rosita and has good access which facilitates the on-going exploration."

The Monte Carmelo Gold Project hosts garnet skarn and structurally-related gold mineralization in a 500 metre by 200-300 metre area and is open for further expansion. Results to date including rock samples up to 16.90g/t Au & rock-soils up to 8.07g/t Au. In many cases the anomalous gold samples contain quartz veinlets, drusy quartz or limonite boxworks and gold mineralization may be more structurally controlled than skarn related and ongoing work is designed to better understand the controls to gold mineralization.

Work to date includes mapping and geochemical sampling with 118 rock and 259 auger rock-soil samples collected in 2015 including 15 rocks and 147 rock-soils in August. Current work comprises detailed 1:5000 scale mapping and systematic auger rock-soil sampling.

The Monte Carmelo Gold Project is underlain by carbonates intruded by granodiorite and granite intrusives resulting in the formation of garnet and iron (hematite and magnetite) skarns, hornfels and silicification. The skarn bodies are elongated with a NW and northern trend and can show quick gradational changes from iron skarn to garnet (brown and green) skarn and calc-silicates normally over a very few meters (up to 5 m) distance and there are frequent compositional intercalations of the two. A central skarn body hosts the principal gold anomaly over a >500 metre by 200-300 metre area with local gold grades >1g/t Au.

Inspection of several small-scale, historic, mine workings (tunnels up to 25 m long) within the Monte Carmelo Target show anomalous gold in fractured zones with/without quartz veins within the garnet skarn unit as well as anomalous gold with limonite boxworks.

Quality assurance and quality control procedures include the systematic insertion of blanks, standards and duplicates into the rock and soil sample strings. Samples are placed in sealed bags and shipped directly to Acme Labs in Managua, Nicaragua for sample preparation and then to Acme Labs in Vancouver, Canada for gold fire assay and ICP-MS multi element analyses.
