Great Panther Silver Extends High Grade Silver-Gold Mineralization and Discovers New Zones at Guanajuato

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 30, 2011) - GREAT PANTHER SILVER LIMITED (TSX:GPR)(NYSE Amex:GPL) (the "Company") is pleased to announce the discovery of additional high grade silver-gold mineralization in an extension of the Cata Mine in the core of the Guanajuato Mine Complex. The discovery was made during the course of a detailed deep drilling program being conducted at 12.5 to 25 metre intervals from several drill stations in the Cata Mine access ramp at the 510 metre level, the deepest mining development to date. The drilling program, covering an area of approximately 70 metres down-dip and 100 metres along strike, has been successful in extending silver-gold mineralization below the current level of mining and the existing mineral resource/reserve estimate.

Using information from mining on the upper levels, older drilling, and the new drilling of holes UG11-132 to 137, inclusive, five mineralized zones are now interpreted from the data: the Veta Madre zone, a new Contact zone, the Alto 1 zone, the Alto 1a zone, and the Alto 2 zone. Other significant intersections do not yet have sufficient definition to correlate between holes and have not been named as discrete zones. The "Alto" zones are believed to be shallow dipping (approximately 20 degrees to the southwest) and southeast plunging hanging-wall splays from the Veta Madre. Typically, the mineralized portion of the zones pinches and swells with true widths varying from less than one metre to approximately five metres.

Highlights of the above observations include Alto 2 zone intersections from UG11-135 that returned 29.44g/t gold and 6,447g/t silver over a width of 3.20 metres, and UG11-137 that returned 7.38g/t gold and 2,114g/t silver over a width of 5.40 metres. The Alto 1a zone in UG11-137 returned 1.82g/t gold and 485g/t silver over a width of 4.80 metres, while the Veta Madre zone in UG11-133 returned 6.02g/t gold and 1,347g/t silver over a width of 2.25 metres. Highlights from the six drill holes completed to date in 2011 are tabulated below, along with several older holes not previously used in the mineral resource estimate.

"The discovery of new high grade mineralization at depth at Cata is very significant as it not only emphasizes the ongoing potential for new discoveries, but the excellent silver and gold grades will go a long way to boosting our overall grades from this part of the mine", stated Robert Archer, Great Panther's President CEO.

Drilling is being conducted from drill stations in the 510 metre level main access to test each of the "Alto" and Veta Madre zones. Similar mineralization is noted to the 530 metre level in previously drilled wide-spaced holes both 25 metres to the southeast (EUG08-021 and 024) and up to 60 metres to the northwest (UGC10-012 and EUG07-002). Geological modeling of the structures is presently ongoing. Six cross sections have been posted on the Company's website at www.greatpanther.com which display the new drilling, intersections with grades and widths, general interpretation, and the bottom of the block model from the latest Cata mineral resource/reserve estimate (Company news release December 15th, 2010).

Presently, exploitation at the Cata Mine is being conducted above the 490 metre level, targeted at the Veta Madre mineralization. Production from this area is currently 180 tonnes per day at grades averaging 1.0g/t gold and 250g/t silver and supplies one third of the metal production from the company's Guanajuato operations. The drilling reported herein was focused on defining the Alto 1, Alto 1a and Alto 2 zones so that they can be sequenced into the mine plan in the latter part of 2011.

There has been virtually no mining of the Alto 1 and 2 zones to date and current Mineral Resources (from the aforementioned December 2010 report) are estimated at 23,000 tonnes grading 2.72g/t gold and 659g/t silver plus 14,000 tonnes grading 2.51g/t gold and 759g/t silver, respectively. These drill results extend the mineralization, and mining of these two zones will start in the fourth quarter as soon as further drilling, currently in progress, has been completed. Plans are underway to extend development along the entire strike length of this area to continue exploratory and definition drilling, access to all of the zones, and provide access to drill further down dip. The drilling will be an integral part of updating the Cata Mine mineral resource/reserve estimate, anticipated for later this year.
