Gran Colombia Gold Announces Additional Drilling Results

About this update from Aris Mining Corp

[{"type":"text","content":"\n\n\n\n\n\nTORONTO, Aug. 28, 2011 /CNW/ - Gran Colombia Gold Corp. (TSX: GCM) is\n pleased to announce drilling results from a further 51 drill holes\n totalling 18,009 metres from its diamond drilling program at the\n Marmato gold project in Colombia. These results, plus all previously\n announced results, will be reflected in an updated NI 43-101 mineral\n resource estimate, expected to be announced in the coming weeks.\n\n\nThe primary focus of the current infill drilling programme has been to\n increase the confidence in the Mineral Resource in the upper portions\n of the deposit, and to increase the confidence in the Inferred\n Resources at depth. The results of the current drilling indicate that a\n large amount of material previously categorised as Inferred Resource is\n likely to be converted into Indicated Resources.\n\n\nThe current infill drilling has also produced a number of intersections\n displaying higher grades at depth. These intersections show a slight\n change in the mineralisation style for the porphyry mineralisation,\n with a lack of veinlet mineralisation, but consistent grades over a\n number of samples, suggesting the possibility of a transitional or\n feeder zone to the main mineralisation.  Further work is required by\n the Company to investigate the depth and strike continuity of these\n zones.\n\n\nHighlights include hole MT-1398 which returned multiple economic\n mineralized intersections, with the best being 0.8 grams per tonne\n (g/t) gold and 2.8 g/t silver over 283 metres. Other highlights include\n hole MT-1414A, which returned 1.5 g/t gold over 92 metres. Significant\n results (greater than 20 gram-metres) are summarized below.\n\n\nDrill Hole #\n\n\nFrom\n\n\nTo\n\n\nLength\n\n\nAu Grade\n\n\nAg Grade\n\n\n \n\n\n(m)\n\n\n(m)\n\n\n  (m)\n\n\n   (g/t)\n\n\n   (g/t)\n\n\nMT-1370\n\n\n187.0\n\n\n208.0\n\n\n21.0\n\n\n1.1\n\n\n6.1\n\n\nand\n\n\n233.0\n\n\n280.0\n\n\n47.0\n\n\n1.1\n\n\n2.9\n\n\nand\n\n\n582.0\n\n\n599.0\n\n\n17.0\n\n\n1.7\n\n\n4.4\n\n\nand\n\n\n648.0\n\n\n677.0\n\n\n29.0\n\n\n0.8\n\n\n1.6\n\n\nMT-1393A*\n\n\n16.0\n\n\n64.2\n\n\n48.2\n\n\n1.0\n\n\n4.5\n\n\nMT-1396A*\n\n\n74.0\n\n\n128.0\n\n\n54.0\n\n\n0.5\n\n\n1.7\n\n\nand\n\n\n136.9\n\n\n186.6\n\n\n49.7\n\n\n0.5\n\n\n3.6\n\n\nand\n\n\n193.0\n\n\n226.1\n\n\n33.1\n\n\n0.6\n\n\n2.6\n\n\nand\n\n\n23...
