VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/16/12 -- B2Gold Corp. (TSX: BTO)(OTCQX: BGLPF) ("B2Gold" or the "Company") and Calibre Mining Corp. (TSX VENTURE: CXB) ("Calibre"), are pleased to announce further positive drill results at the Primavera Gold and Copper Porphyry joint venture project in the productive Bonanza-Siuna-Rosita mining triangle in the North of Nicaragua.
Drilling resumed early in 2012 with the deepening of the third hole which was not completed due to the holiday break. In addition to completing the third drill hole (PR-11-003), another seven drill holes totaling 3,199 m have now been completed and results have been received up to drill hole PR-12-009 and partial results for PR-12-010. Significant intercepts include PR-11-003 at 146.5 metres of 0.65 grams per tonne ("g/t") gold and 0.27% copper, PR-12-005 at 46 metres of 0.48 g/t gold and 0.32% copper and PR-12-008, with 172.35 metres at 0.48 g/t gold and 0.24% copper (including 55.5 metres at 0.67 g/t gold and 0.36% copper).
The drill program for 2012 has focused on large step outs from the known mineralization intersected in the first three drill holes. The step-outs were located in all directions from the original drill collars. Mineralization and porphyry style alteration remains open to the northeast and southeast and potentially beyond an apparent normal fault, which has displaced the mineralization to the west and northwest. Porphyry mineralization similar to that intersected in the first three holes was intersected to the northwest (PR-12-005) and west (PR-12-008) while propylitic alteration and associated mineralization was encountered to the northeast (PR-12-006 and PR-12-007). Anomalous gold and copper grades are associated with chalcopyrite and bornite sulfide mineralization that occurs as disseminations and within quartz stockworking within volcanic and intrusive lithologies. Drill hole PR-12-010 was collared over 400 metres to the southeast and intersected a polymetallic quartz vein which yielded 15.4 metres of 0.59 g/t gold and 0.43% copper. The vein cut in the drilling can be traced over one kilometre on surface based on soil and rock sampling as well as the presence of old workings. Further drilling will be needed to establish the potential of this structure. Drill hole 11 is ongoing and is located 120 metres east of hole 2. The top 90 metres have intersected mineralization that visually looks similar to hole 2. Assay results are pending for hole 11.

Note: Hole PR-12-010 was analyzed at Inspectorate's Labs in Vancouver.
Commensurate with the drilling over the last month, detailed soil sampling and mapping has been initiated to develop additional drill targets. In addition airborne magnetic - radiometric, LIDAR and IP surveys are to commence shortly. Porphyry systems are known to occur in clusters and other vein targets have also been located based on earlier work by Calibre.
Exploration going forward will continue with two drills with the focus on infill drilling of the main Primavera zone as well as the testing of additional porphyry and vein targets. Drilling will also test for the displaced mineralization to the west of the main Primavera zone. Detailed mapping and soil sampling will be important to better define potential drill targets. Since access and infrastructure are so favorable at Primavera, B2Gold expects that the exploration program can progress quickly.
Quality assurance and quality control procedures include the systematic insertion of blanks, standards and duplicates into the rock sample strings. Samples are placed in sealed bags and shipped directly to Inspectorate Labs in Managua, Nicaragua for sample preparation. A split was sent from Inspectorate to ALS Labs in Vancouver for gold and silver fire assay and ICP multi-element analysis. Hole PR-12-010 has been analyzed at Inspectorate's lab in Vancouver for gold and silver fire assay and ICP multi-element.
