Great Panther Silver Eliminates Backlog of Concentrate Inventory at Guanajuato and Provides 2012 Production Estimates

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 15, 2011) - GREAT PANTHER SILVER LIMITED (TSX:GPR)(NYSE Amex:GPL) (the "Company") is pleased to announce that it has finalized arrangements to sell all available concentrate inventories from Guanajuato before year end and is well advanced in securing new contracts for fiscal 2012 concentrate sales for both the Guanajuato and Topia Mines. This will ensure strong fourth quarter revenues which will balance out the previous revenue shortfall in the second quarter. Precious metal rich lead and zinc concentrates from Topia are typically sold to traders, destined for the Asian smelting market, whereas precious metal rich concentrates from Guanajuato are typically sold directly to smelters.

Looking forward to next year, the Company expects metal production growth of approximately 20% year on year from its two wholly owned Mexican silver operations. The Company estimates metal production in the range of 2.50 to 2.75 million silver equivalent ounces ("Ag eq oz"), for fiscal 2012.

In terms of contained metals, the Company's estimated ranges for 2012 are as follows:

  • Silver: 1.72 to 1.90 million ounces, up from approximately 1.51 million ounces in 2011.
  • Gold: 10,000 to 11,000 ounces, up from approximately 7,800 ounces in 2011.
  • Lead: 2.50 to 2.80 million pounds, up from approximately 2.00 million pounds in 2011.
  • Zinc: 3.30 to 3.60 million pounds, up from approximately 2.90 million pounds in 2011.

(Silver equivalents for 2012 have been established using prices of US$1,680/oz Au; US$28/oz Ag; and US$0.85/lb for Pb and Zn).

"We congratulate our marketing team for successfully restoring the concentrate inventory at Guanajuato to normal levels and we are pleased that there appears to be a healthy market for our anticipated 2012 production", stated Robert Archer, President & CEO. "We are finalizing our budgets for significant capital and exploration expenditures for 2012 to ensure we meet our growth projections at both operations. However, considering the extreme grade variability we have experienced this past year, particularly at Guanajuato, we feel that it is prudent to provide for a fairly conservative range of production outcomes for 2012, even though we will be striving to achieve a higher output."

Operations are on track to achieve the fourth quarter target of 0.55 million Ag eq oz. Ore grades processed at the Guanajuato Mine Complex in November averaged 220g/t Ag and 1.78g/t Au, up significantly from the grades of 175g/t Ag and 1.12g/t Au, in the third quarter. High grade ore from the development of the Deep Cata Alto zones started to be processed towards the end of October and made an immediate impact. This high grade development has continued through December and, as stoping is established, ore grades are expected to remain strong throughout 2012. Ore throughput is estimated to increase to 200,000 tonnes in 2012, from 170,000 tonnes in 2011, due to planned expansions of output at the Guanajuatito and Santa Margarita zones.

At Guanajuatito, the new 160 metre level is being developed and the decline access ramp will be extended to the 200 and 240 metre levels during 2012. Development on the 455 metre level at Santa Margarita is underway and this will be followed by access to the 475 metre level to facilitate the production increase from these gold-rich veins, contributing significantly to the increased gold production. The plant capacity, currently at 1,050 tonnes per day, is more than sufficient to handle this expansion and further improvements in metallurgical performance are anticipated.

At Topia, ore grades are expected to be similar to 2011 as the expansion of the 15 small mines continues with a significant increase in throughput to 58,000 tonnes, up from 47,000 tonnes in 2011. The newly developed La Prieta Mine, Level 3 of the Argentina Mine, and new levels on the San Gregorio and El Rosario veins, plus planned expansions in most of the other small mines, will contribute to the increased throughput. The crushing and flotation sections of the processing plant are being improved through the next two quarters to further increase capacity to approximately 300 tonnes per day, which is more than sufficient for current and future production expansions.

The breakdown of metals by mine is shown in the table below.

Guanajuato Topia Total
Metal Unit From To From To From To
Ag M oz 1.11 1.23 0.61 0.67 1.72 1.90
Au oz 9,000 9,800 1,000 1,200 10,000 11,000
