Vancouver, British Columbia: Calibre Mining Corp. (TSX-V: CXB) (the "Company" or "Calibre") is pleased to announce that the Company and IAMGOLD Corporation ("IAMGOLD") have started the 2014 diamond drilling program on the Eastern Borosi Gold-Silver Project, Nicaragua.
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.
- Drilling equipment has been mobilized and drilling has commenced on the 3400 metre 2014 drill program
- The 2014 drilling program will comprise an estimated 31 diamond drill holes designed to test approximately 3.0 kilometres of strike length of previously identified gold-silver bearing structures.
- Drilling will test a number of high priority gold-silver targets including; Guapinol, Riscos de Oro extension, Blag, California, Veta Vancouver, and Veta Toronto.
- The current drilling program utilizing one drill rig is expected to take three months to be completed.
President and CEO, Greg Smith stated: "We are excited to start the drilling program on the Eastern Borosi Project. The series of high quality drill targets represent more than three kilometres of potential gold-silver bearing structures within the tens of kilometres of potential structures which have been identified within this prolific district."
Drilling has begun on the Guapinol Gold-Silver Target which has been prioritized based on previous exploration including; surface mapping, historic underground development and previous shallow drilling as well as soil and rock geochemistry and LIDAR surveying. At Guapinol surface channel sampling completed by Calibre include: 1.3 metres @ 21.0 g/t Au and 13.3 g/t Ag, and 0.9 metres @ 9.6 g/t Au and 108.0 g/t Ag.
The Eastern Borosi Project includes the Riscos de Oro and La Luna NI 43-101 Inferred Mineral Resources which total 4.70 million tonnes grading 2.31 g/t Au and 34.99 g/t Ag containing 350,000 ounces of gold and 5.29 million ounces of silver. Both zones are open for potential expansion. See Calibre News Release dated May 27, 2014 for details.
