[{"type":"text","content":"\n\n\n\nVANCOUVER, Feb. 28 /CNW/ - Mirasol Resources Ltd. (TSX-V: MRZ; Frankfurt:\nM8R) is pleased to announce broad intervals of silver-gold-lead mineralization\nfrom channel sampling of the Cerro Plomo prospect at its 100%-owned Libanesa\nProject, Santa Cruz Province, Argentina.\n\n\nAt Cerro Plomo, a 50 by 50 metre exposure of hydrothermal breccias and\nfracture veining crops out at the edge of a salt pan (see press release\nJuly 27, 2007). Mirasol completed one hundred and thirty meters of backhoe\ntrenches and outcrop channel sampling which partially tested the southern\nextent of the mineralized outcrop at the edge of the salt pan.\n\n\nTrenching extended the area of outcropping breccia and showed that while\nthe breccia is closed off in the trenches, it is surrounded by a zone of\njarosite (iron oxide) fracture veining in the wall rock that remains open to\nthe south. The trenches carry anomalous values over their full lengths due to\nthe fracture veining (see Table 1). Length-weighted average results for the\nfull length of the trenches include 27.7 metres of 14.5 g/t silver,\n0.45 g/t gold and 0.84% lead; 13.35 metres of 52.0 g/t silver, 0.74 g/t gold\nand 0.85% lead, and 9.65 metres of 151.6 g/t silver, 0.53 g/t gold and\n2.13% lead.\n\n\nTwenty-three select samples of the breccias' matrix and fracture veins\nfrom the Cerro Plomo zone (see Table 2) averaged 325 g/t silver, 0.59 g/t gold\nand 3.54% lead, with individual samples up to 2830 g/t silver, 2.21 g/t gold\nand 48.45% lead. This suggests the potential for bonanza grade mineralization\nwhere the breccias' matrix and veining become volumetrically more significant.\n\n\n-----------------------------------------------------------------\n\nTable 1: Cerro Plomo Breccia - Trench Results\n-----------------------------------------------------------------\n Interval Silver Gold Lead\n Trench meters g/t g/t %\n-----------------------------------------------------------------\nFull length of trench C_1 13.35 52.0 0.74 0.85\n-----------------------------------------------------------------\nincluding 3.7 93.1 0.94 1.53\n-----------------------------------------------------------------\nFull length of trench C_2 9.65 151.6 0.53 2.13\n-----------------------------------------------------------------\nincluding 5.15 248.1 0.81 3.49\n---------------------------------------------...
