Vancouver, British Columbia: Calibre Mining Corp. (TSX-V: CXB) (the "Company" or "Calibre") is pleased to announce assay results for the second set of six diamond drill holes from the on-going Phase I Drilling Program on the Eastern Borosi Gold-Silver Project which is being funded under an option agreement with IAMGOLD Corporation ("IAMGOLD").
Highlights
- The Phase I Drilling Program has completed 22 of a planned 30 diamond drill holes and assay results have been received for the first 12 drill holes
- New high grade gold drill intercepts include; 6.50 metres grading 16.88 g/t Au and 20.95 g/t Ag, including 1.82 metres grading 45.79 g/t Au and 32.39 g/t Ag (Drill Hole GP14-010)
- The first 9 drill holes tested the Guapinol gold-silver vein system over a strike length of 670 metres and to a depth of 100 metres with the next 3 drill holes targeting the adjacent Vancouver gold-silver vein system over a strike length of 200 metres and to a depth of 80 metres. Mineralization remains open down plunge from the reported intercepts and potential exists for additional mineralized zones along the strike of both structures.
President and CEO, Greg Smith stated: "This second set of results for the on-going Eastern Borosi Project drilling program includes a second high grade gold discovery which was intersected in the first ever drill hole on the Vancouver gold-silver vein system located 250 metres south-east of the high grade gold discovery on the Guapinol structure. All drill holes completed to date continue to intersect the targeted mineralized structures. The drilling program continues to progress on schedule and on budget and additional assay results will be released when available".

Calibre and IAMGOLD entered into an option agreement dated May 26, 2014 whereby IAMGOLD can earn a 51% interest in the Eastern Borosi Gold-Silver Project consisting of 176 km2 within the Borosi Concessions, Northeast Nicaragua, by incurring US$5 million in exploration expenditures and making US$450,000 in payments to Calibre over 3 years. The total potential investment by IAMGOLD to earn a 70% interest in the Eastern Borosi Project is US$10.9 million. The Eastern Borosi Project hosts gold-silver resources in two deposits and a series of well-defined low sulphidation epithermal gold-silver targets.
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.
Additional completed drill holes include holes GP14-015 through GP14-018 which targeted 340 metres of the California structure located one kilometre north of drill hole GP14-008. Drilling is currently testing the Blag Structure, located three kilometres northeast of the California structure, where to date four holes BL14-0001 through BL14-004 have been completed.
Low sulphidation epithermal gold-silver mineralization intersected at the Guapinol and Vancouver 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 30 diamond drill holes designed to test approximately 3.0 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.
