Jan 11 (Reuters) - Great Panther Silver Ltd GPR.TO reported 2009 metal production that beat its earlier estimates by 6 percent, helped by improved performance at the Canadian company's two Mexican mines, and backed its 2010 production outlook.
The company posted yearly production of 2,202,456 silver equivalent ounces, higher than the previous target of 2.07 million ounces, and backed its 2010 production outlook of 2.5 million ounces.
Metal production for the fourth quarter rose 26 percent to 625,288 silver equivalent ounces, as its mines at Topia and Guanajuato reportedly continued to ramp up operations.
Silver production for the quarter was up 9 percent at 390,026 ounces, while gold production was up 53 percent at 2,456 ounces, from the year-ago period.
The company expects to produce 3.8 million silver equivalent ounces by 2012.
