Great Panther Silver LTD (TSE: GPR) reported record silver production at its two 100 percent-owned Topia and Guanajuato silver mines in Mexico. Combined silver production increased 23 percent from Q2 2009 to total 410,583 ounces for Q2 2010. A total of 1,474 ounces of gold were also produced. Great Panther Silver is on its way toward meeting its target of 3.8 million Ag eq oz in 2012 with its 3- year growth strategy of increasing production by 20 percent per year. Part of this strategy involves new and efficient mining equipment at both Topia and Guanajuato. The addition of 2-yard underground loaders, a scissor-lift utility truck, a single-boom electric-hydraulic drill jumbo and 16-tonne capacity underground haulage truck will go a long way towards further increasing production rates in the second half of 2010. Bear Creek Mining Corporation (CVE: BCM) announced Monday the fourth resource estimate results on its wholly-owned Santa Ana leachable silver deposit in Peru.

The company also anticipates filing an Environmental and Social Impact Assessment by the end of 2010.
