[{"type":"text","content":"\n\n\n\nVANCOUVER, Feb. 27 /CNW/ - Mirasol Resources Ltd. (TSX-V: MRZ; Frankfurt:\nM8R) is pleased to present an exploration update and to announce upgrading of\nits wholly owned Libanesa project. New high-grade silver and gold showings\nhave been identified adjacent to the previously reported Cerro Plomo\nsilver-gold-lead breccias at Libanesa, Santa Cruz Province, southern\nArgentina.\n\n\nExploration completed since the last press release (February 28, 2008)\nincludes: follow-up prospecting of Mobile Metal Ion (MMI) soil anomalies, an\ninduced polarization (IP) geophysical survey, additional geological mapping\nand petrographic studies of the newly discovered mineralization. Recent work\nhas broadened knowledge of the property and provided additional exploration\nconcepts and targets.\n\n\nMineralization at Libanesa is developed as localized hydrothermal and\nphreatic breccias, sulphide - quartz veining and gossans associated with a 2\nkm diameter, radial-dyke swarm. The geochemical signature of mineralization is\nsilver, gold, and base metal-dominant with anomalous tellurium, seen in veins\nperipheral to the Cerro Plomo breccia.\n\n\nShallow soil and gravel cover much of the prospect area, potentially\nconcealing additional mineralization. Processing of the MMI soil results\nsuggests that mineralization at Libanesa falls along two northeast trending\ncorridors (Figure 1 - http://files.newswire.ca/786/Libanesa.JPG) that are up\nto 1400 metres long. The more pronounced northern belt hosts the Cerro Plomo\nbreccias and three new showings of mineralization found at Bajo Aspero, Anibal\nand Zona NE, which are associated with phreatic breccias. The phreatic\nbreccias have silicified matrix, are often anomalous in silver, arsenic,\nmolybdenum, lead or zinc, but appear to predate the main mineralized phase of\nhydrothermal breccias and veining.\n\n\nAt the Bajo Aspero prospect located 300 metres west of Cerro Plomo, a\ncluster of gossan blocks believed to be completely-oxidized, sulphide\nmineralization has assayed 18 g/t gold, 10 g/t silver and 1.96% lead (Table\n1). The size, orientation and nature of the gossan body has not yet been\ndetermined, but it is spatially associated with nearby phreatic breccias which\ncut altered tuffs that are in turn cut by occasional crystalline quartz veins.\n\n\nAt the Anibal prospect 200m north of...
