Looking to turn up the heat this summer. B2Gold and Calibre Mining released the final Phase I drill results from the

Primavera Gold and Copper Porphyry joint venture project in Nicaragua. Highlight intersections from the remaining three drill

holes included: 1) 159.53 m of 0.46 g/t gold and 0.20% copper (hole PR-12-011); ii) 97 m of 0.34 g/t gold and 0.16% copper

(hole PR-12-012); and, iii) 22.5 m of 0.44 g/t gold and 0.21% copper (hole PR-12-013). All three drill holes lie along the

eastern side of the Primavera porphyry deposit and northwest of the vein cut in drill hole PR-12-010. The partners

also highlighted that a 10,000-m Phase II drilling program at Primavera began in mid-June with one drill rig, and a second drill

is expected on site in the next month. In addition to the drilling, an aggressive exploration effort including a Lidar topographic

survey, air-mag, and IP as well as regional soil sampling is in progress. Phase II drilling will concentrate on expansion of the

main Primavera zone, additional drilling along the northeast trending vein zone to the south of Primavera, and test for the offset

porphyry mineralization at Copper Hill and the intervening covered area in between Primavera and Copper Hill itself. Also

several drill holes will be located peripheral to the main porphyry discovery where anomalous soil samples were not

investigated in the first phase of drilling.
