[{"type":"text","content":"\n\n\nVANCOUVER, July 23, 2014 /CNW/ - Mirasol Resources Ltd. (TSX-V: MRZ, Frankfurt: M8R)\n\n\n\nAt the AGZ (Atlas Gold Zone) prospect surface rock chip sampling has\n outlined an 800 by 500 m area hosting multiple gold-anomalous\n quartz-alunite alteration trends, with 55 of 473 rock chips assaying\n between 1.0 and 50.3 g/t gold.\n\n\n\n\nDetailed re-sampling of existing AGZ trenches which lie within the area\n of the rock chip gold anomaly returned best length-weighted average\n channel samples of:\n\n\n\n\n\n8.4 m at 1.85 g/t Au and 0.5 g/t Ag\n\n\n11.3 m at 1.32 g/t Au and 7.3 g/t Ag\n\n\n14.9 m at 1.67 g/t Au and 0.6 g/t Ag\n\n\n\n\n\nHighest individual channel samples from the re-sampled trenches include\n 1.2 m at 8.85 g/t Au and 45.8 g/t Ag, and 1.0 m at 5.63 g/t Au and 5.13\n g/t Ag.\n\n\n\nMirasol Resources recently reported that it had outlined an 800 by 500 m\n zone of anomalous gold and silver mineralization in rock chip float and\n subcrop samples at its 100%-owned Atlas AGZ prospect (Figure 1; and see news release of July 18, 2014). Of the 473 rock chip samples\n collected here, 55 have assayed between 1.0 to 50.3 g/t Au.  These\n higher-grade samples are interpreted to define a series of\n northwest-trending quartz-alunite alteration zones with vuggy silica\n and hydrothermal breccias, hosted by andesitic lava flows, or an\n andesitic flow dome.\n\n\nThe gold - silver trends are spatially associated with a 1 km long,\n opened-ended highly resistive geophysical anomaly defined in Mirasol's\n recent IP survey at Atlas. These resistive anomalies may represent\n hydrothermal feeder zones or buried flow domes.  Anomalous rock chip\n samples with assays in the range 0.1 to 30.7 g/t Au and with Ag assays\n up to 56.9 g/t occur on the margin, or over the top, of the buried\n resistive anomalies potentially representing geochemical leakage from\n the covered geophysical features.            \n\n\nMirasol also recently completed a detailed re-mapping and channel\n re-sampling program (Figure 2) over the existing trenches at the AGZ prospect to better understand\n the mineralization in the trenches and its relationship to the Au and\n Ag-bearing quartz-alunite zones at surface. The best length-weighted\n average trench channel results (Table 1) from this season's...
