Calibre Initiates Major Resource Delineation Drill Program at 100% Owned Riscos de Oro Gold-Silver Project, Nicaragua

24 ago. 2011

Vancouver, British Columbia: Edward Farrauto, President and CEO of Calibre Mining Corp. (TSX-V: CXB) (the "Company" or "Calibre") is pleased to announce that the Company has commenced a planned 6,000 metre diamond drill program at its 100% owned, Riscos de Oro epithermal gold-silver vein stockwork system in northeast Nicaragua.

Calibre has previously completed two drilling programs at the Riscos de Oro project totalling 4,600 metres, which successfully delineated high-grade gold and silver mineralization over a strike length of 600 metres and to a depth of 300 metres. Highlights from the previous drill programs include hole RD10-009 which intersected 4.23 g/t gold and 384.86 g/t silver over 8.53 metres; hole RD11-010 intersected 10.25 g/t gold and 288.25 g/t silver over 5.40 metres; and hole RD11-012 that intersected 7.69 g/t gold and 211.87 g/t silver over 10.60 metres.

Edward Farrauto, President and CEO of Calibre stated: "We are pleased to initiate an extensive resource delineation drill program at our 100% owned Riscos de Oro gold-silver deposit. This impressive, high grade gold-silver system is open for expansion in all directions. On completion of the current drill campaign Calibre intends to complete the first NI 43-101 resource estimate for the Riscos de Oro deposit".

The current resource delineation drill program will be Calibre's most significant and extensive exploration program to date. The program will include:

  • infill and step out drilling in order to define the full extent of the high-grade gold-silver mineralization encountered in previous drilling;
  • reconnaissance drilling to test new gold in soil anomalies along the 7.0 km long structure that hosts the Riscos de Oro deposit
  • deeper drilling in order to better define the extent and geometry of multiple stacked gold-silver stockwork zones

The program will initially be undertaken with one drill rig with a second rig being mobilized to the project by September 2011. The total budget for this diamond drilling program is $1.6 million. An up-to-date drill plan map and longitudinal section are available at
