VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 15, 2013) - GREAT PANTHER SILVER LIMITED (News - Market indicators)(NYSE MKT:GPL) (the "Company") today reports first quarter ("Q1") production at its two wholly-owned Mexican silver mining operations, Guanajuato and Topia.

First Quarter 2013 Highlights (Compared to First Quarter 2012)

• Ore processed was up 36% to 69,540 tonnes;
• Metal production increased 9% to 607,501 silver equivalent ounces ("Ag eq oz") (at a 60:1 silver:gold ratio);
• Silver production rose 3% to 369,624 silver ounces ("Ag oz"); and
• Gold production saw a 15% increase to 3,144 gold ounces ("Au oz").

"We are pleased that our operational results for Q1 were ahead of plan and we expect that the cost reduction and efficiency efforts we have initiated will begin to be realized in future quarters" stated Bob Archer, CEO. "Our focus for the remainder of 2013 will be on grade and cost controls at both operations, advancement of development at San Ignacio and pushing ahead with the drill program at El Horcon" added Mr. Archer. 

Guanajuato Mine Complex

For the first quarter, the Guanajuato operation processed 52,545 tonnes, up 35% compared to the same period in 2012, at ore grades of 148g/t silver ("Ag") and 1.93g/t gold ("Au"). Metal production included 222,906 Ag oz, and 2,942 Au oz, or 399,417 Ag eq oz, which represented an increase of 1% over the same period in 2012. Plant metallurgical performance remained strong with metal recoveries of 89.2% for silver and 90.3% for gold.

The majority of the metal production during the quarter was from the lower levels of Cata and Santa Margarita. Silver grades were lower than anticipated across all zones but the most noticeable impact was from the lower than expected silver grades at the 525 metre level of Cata. Looking ahead, the focus at the Guanajuato operation will be on grade control as these lower grades will have a measureable impact on operating costs.

Development towards the 510 metre level continued along the Santa Margarita main ramp. Exploration drilling was carried out in parallel to identify the orientation of the mineralized structures.

Exploration drilling was carried out in Cata at the 525 metre level, aiming to accurately define the mineralized block through short boreholes between the 525 and 550 metre levels as the ramp is extended to depth.

During the quarter, improvements were made to the crushing section of the Cata processing plant by optimizing the double-deck screen installed in the fourth quarter. In addition, the installation of a HP300 Cone Crusher significantly improved the crushing capacity at the plant.

Topia Mine

For the first quarter, 16,995 tonnes were processed at Topia, up 37% compared to the same period in 2012, at ore grades of 300g/t Ag, 0.65g/t Au, 1.81% lead ("Pb") and 2.94% zinc ("Zn").

Metal production included 146,718 Ag oz, 202 Au oz, 631,373 Pb lbs, and 989,416 Zn lbs, or 208,084 Ag eq oz, which is up 29% over the same period in 2012.

Plant metallurgical performance was satisfactory with metal recoveries of 89.4% for silver, 56.6% for gold, 93.2% for lead, and 89.7% for zinc.

Metal production from Topia's main mines, the 1522 mine and Durangueño, experienced increasingly narrow vein formations which resulted in higher dilution and lower silver grades for the quarter. Management is conducting a mine by mine review of the 14 Topia mines to determine where to best concentrate its mining efforts.

San Ignacio Project

During the first quarter the Company received the explosives permit and began the rehabilitation of the San Ignacio surface infrastructure (offices, electrical installations, etc.) to prepare for the commencement of mining development activities.

It is expected that the Land Use permit and the Environmental Impact Assessment approvals will be received in the third quarter.

El Horcon

At El Horcon the baseline studies for the Ministry of Environment and Natural Resources, SEMARNAT ("Secretaría de Medio Ambiente y Recursos Naturales") has been completed and the permit to drill at El Horcon was received on April 9, 2013.

A surface drill program is planned to commence immediately (mid-April 2013). It will consist of 30 drill holes for a total of 3,000 metres. The program is laid out along an 800 metre length of the Diamantillo vein and will test the Diamantillo vein as well as various splays and nearby parallel structures and veins.

Outlook

The focus for 2013 is to improve and strengthen the operational efficiency of the existing operations and expand the platform for more significant growth in 2014 and beyond. 

The Company confirms its estimate of metal production in the range of 2.4 to 2.5 million silver equivalent ounces for 2013, while the goals for this year are to:

1. Increase cash flow from mine operations by cutting costs and improving operating efficiency;
2. Aggressively drive the development of San Ignacio with the view to production in 2014, to augment existing production at Guanajuato;
3. Commence the exploration drilling at El Horcon; and
4. Review acquisition opportunities.
