[{"type":"text","content":"\n\n\n\n\n\nVANCOUVER, April 18, 2012 /CNW/ - Mirasol Resources Ltd. (TSX-V: MRZ) (Frankfurt: M8R) (\"Mirasol\" or \"the Company\") is pleased to announce discovery of a\n large new epithermal gold-silver zone at its 100%-owned Claudia\n project, which adjoins the world class Cerro Vanguardia gold mine,\n operated by Anglogold Ashanti, in southern Argentina. This release\n reports results from the Curahue prospect where a recent geophysical\n survey has defined a 8 km long zone of largely gravel covered anomalies\n that geological evidence suggests is an extensive vein zone.  Rock chip\n samples, from locally sourced epithermal cobbles in an alluvial terrace\n that partially covers the zone, returned assays up to 2.0 g/t (grams\n per tonne) gold and 2130.0 g/t silver.  Trenching through gravel and\n rare outcrop was carried out to test geophysical anomalies, and\n returned assays up to 0.9 metres at 4.7 g/t (grams per tonne) gold with\n 120.0 g/t silver from outcropping epithermal veins in bedrock, and up\n to 26 metres at 0.45 g/t gold and 1.9 g/t silver from a veinlet zone.\n\n\nCurahue is one of three prospect areas in the Claudia project currently\n being aggressively explored by Mirasol (see Rio Seco news release March\n 5, 2012).  Curahue is delimited by a 15 km long zone of prominent\n northwest oriented regional structures evident in ground and air\n magnetic images.  The prospect is dominated by shallow gravel cover\n with local erosional windows which reveal underlying Jurassic volcanics\n that host precious metals mineralization.  A prominent feature of the\n Curahue prospect is a 2.5 by 1 km alluvial terrace dominantly composed\n of gold- and silver-mineralized epithermal quartz cobbles. Sampling of\n the cobbles has returned multiple gold assays up to 2.0 g/t gold and an\n isolated, peak silver assay of 2130.0 g/t silver from a sample with\n visible ruby silver minerals.  Mirasol's geologists interpret the\n epithermal cobble terrace to be sourced from erosion of a vein zone\n concealed by the shallow gravel and soil cover.\n\n\nPrevious exploration on the Curahue trend was initiated by Mirasol and\n later continued by a previous joint venture partner that returned the\n project to Mirasol in 2009. Work included partial coverage of the trend\n with ground magnetic geophysical surve...
