Calibre Mining Announces Additional Drilling Results From the Eastern Borosi Gold-Silver Project Including 6.73 Metres Grading 4.11 g/t Gold and 235.90 g/t Silver - Seite 2

Completed Drill Holes - Assays Received and Reported

The current drilling program has been designed to test the strike extent of the known gold/silver-bearing structures on a portion of the Eastern Borosi project. The first nine holes (GP14-001 through GP14-009) were drilled on the Guapinol gold-silver vein system testing 670 metres of strike length. Drill holes GP14-010 through GP14-014 targeted 420 metres of the Vancouver gold-silver vein system located approximately 250 metres south-east of the Guapinol structure. Drill holes GP14-015 through GP14-018 targeted 340 metres of the California structure located one kilometre north of drill hole GP14-008. Five drill holes (BL14-001 to BL14-005) tested 250 metres of the Blag gold-silver vein system, located three kilometres northeast of the California structure.

Completed Drill Holes - Assays Pending

Three drill holes (RD14-038 to RD14-040) have been completed on an extension of the Riscos de Oro vein system approximately 500 metres NE of the existing NI 43-101 Inferred gold-silver resource. Two drill holes (GP14-019 and GP14-020) tested an additional 200 metres of the Guapinol gold-silver vein system (1,120 metres total strike-length) to the south-west of GP14-009 that intercepted 0.98 metres grading 7.3 g/t Au with an additional drill hole GP14-024 testing the structure a further 100 metres to the north-east. Three drill holes (GP14-021, GP14-022 and GP14-023) tested an additional 300 metres of the Vancouver gold-silver vein system (765 metres total strike-length) to the south-west of GP14-010 that intercepted 12.90 metres grading 8.73 g/t Au.

Low sulphidation epithermal gold-silver mineralization intersected at the Eastern Borosi Project gold-silver vein systems are hosted within porphyritic andesite and consists of structurally controlled, high energy quartz-carbonate vein breccias, vein-stockworks and discrete smokey quartz veins containing fine grained sulphide minerals. The 2014 drilling program will comprise an estimated 45 diamond drill holes (>5000 metres) designed to test approximately 4.0 kilometres of strike length of previously identified gold-silver bearing structures.

Updated maps detailing the drilling program at the Eastern Borosi Project will be posted on the Company's web site at www.calibremining.com.

Calibre is committed to best practice standards for all exploration, sampling and drilling activities. Drilling is being completed by independent firm Kluane Drilling Ltd. Analytical quality assurance and quality control procedures include the systematic insertion of blanks, standards and duplicates into the sample strings. Samples are placed in sealed bags and shipped directly to Acme Labs (a Bureau Veritas Group Company) in Managua, Nicaragua for sample preparation and then to Acme Labs in Vancouver, Canada for 50 gram gold fire assay and ICP-MS multi element analyses.
