Calibre Mining Corp. (TSX VENTURE:CXB) has announced encouraging gold exploration results from the 100% owned Bonanza H1 Concession in Nicaragua. A combination of mapping, prospecting, soil sampling and trenching over a 2.5 km x 2.0 km area has delineated several sets of gold-bearing quartz veins extending northeast for 2.5 kilometres from the southern concession boundary.
Highlights of the trenching work include 4.7 metres grading 7.30 gram per tonne ("g/t") gold in Trench BTR10-18 and 10.9 metres grading 1.35 g/t gold in Trench BTR10-29. Results from these trenches confirm that mineralization extends at least 600 metres on strike of what is inferred to be the northeast extension of the Washington vein, part of the Panama group of low sulphidation gold veins, currently being mined by Hemco Nicaragua SA ("Hemco").
A series of six trenches were cut across two sub-parallel silicified zones containing quartz veins and crystalline quartz veinlets within argillic altered andesite volcanics. Trenches from the western most vein, outboard of the main structural trend, returned anomalous results. The two trenches that cut across the inferred strike extension of the Washington Vein returned significant results, summarized below.
Exploration of the Bonanza H1 Concession is ongoing; once all results are compiled Calibre will review potential diamond drill targets that will test the depth and strike continuity of the system.
Quality assurance and quality control procedures include the systematic insertion of blanks, standards and duplicates into the soil and rock sample strings. Samples are placed in sealed bags and shipped directly to ALS CHEMEX labs in North Vancouver, BC for gold fire assay and ICP multi element analyses.
