Douglas Forster, Chairman of Calibre stated: “Calibre's Phase II drill program continues to expand gold-silver mineralization at the Riscos de Oro project. Particularly significant is Drill Hole RD11-029 which intersected excellent grade gold and silver mineralization in an area previously interpreted as unmineralized as a result of a gap in drilling information.“

Drilling has been paused awaiting receipt of the additional assays for the remaining drill holes completed to date. As detailed in a previous Calibre news release dated December 6, 2011, the drilling program is designed to further delineate high grade epithermal gold-silver vein stockwork mineralization encountered in previous drilling including 7.69 g/t Au and 211.80 g/t Ag over 10.6 metres in RD11-012 and 10.25 g/t Au and 288.25 g/t Ag over 5.4 metres in RD11-010.

Quality assurance and quality control procedures include the systematic insertion of blanks, standards and duplicates into the rock sample strings. Samples are placed in sealed bags and shipped directly to Inspectorate Labs in Managua, Nicaragua for sample preparation and then to Inspectorate Labs in Vancouver, Canada for gold and silver fire assay and ICP multi element analyses.
