Borosi Gold, Silver and Copper concessions The 100% Calibre owned Borosi concessions cover over 785 square kilometres in northeastern Nicaragua. The Mining Triangle has been one of the most prolific mining districts in Central America with a rich history of mining. Calibre has a NI 43-101 compliant inferred resource totaling 1,057,750 ounces of gold and 8,430,070 ounces of silver on the 100% owned Cerro Aeropuerto, La Luna and Riscos de Oro Prospects and a NI 43-101 compliant inferred resource totaling 118,000 ounces of gold, 2,350,000 ounces of silver and 108,000,000 pounds of copper on the Rosita Prospect which is subject to a joint venture with Alder Resources.

They have an option to go up to 70% by spending an additional $6M over 3 years. MONTES de Oro (100%) Primavera Rosita Calibre has recently discovered new gold-silver-copperzinc mineralization at the Montes de Oro target, North of the Cerro Aeropuerto gold-silver resource. The company is very excited about this new discovery and additional exploration work is underway. Calibre, in conjunction with B2Gold, continues to advance Primavera gold-copper project. Primavera is the site of a significant gold and copper soil anomaly covering an area of 800 by 300 metres (open). An approved phase I $2.0M exploration program is underway including additional step out and infill drilling as well as drilling additional gold/copper soil geochem anomalies that have been outlined in the 25 km2 Primavera porphyry target area. Calibre optioned the Rosita D concession to Alder Resources Ltd., Alder may earn a 65% interest in the Rosita D concession by spending $4 million on exploration. Phase 1 exploration program commenced Dec 2011 which includes 5,000m of RC drilling and 8,000m of diamond drilling. gold/silver/Copper/Zinc project project highlights Partially tested a strong gold-silver-copper anomaly extending over a 400 by 650 metre area which remains open to the northeast. iscovery trenching Highlights include: D TR13-009 - 52.3 metres grading 7.1 g/t gold M TR13-017 - 23.0 metres grading 5.35 g/t gold M Riscos de Oro (100%) gold/silver project Calibre has completed over 9,400 metres of diamond drilling (37 holes) at the 100% owned Riscos de Oro Epithermal Gold-Silver Project.
