Great Panther Silver Intersects High Grade Silver-Gold Mineralization And Discovers Two New Zones At Guanajuato Mine Complex

February 5, 2013

GREAT PANTHER SILVER LIMITED (TSX: GPR)(NYSE MKT: GPL) (or "the Company") is pleased to announce that underground drilling programs at the Company's wholly owned Guanajuato Mine Complex have been successful in intersecting high grade silver-gold mineralization in the historic Valenciana Mine area and discovering two new zones of silver-gold mineralization in the Guanajuatito Mine area.

The drilling at Valenciana included an intercept of 2,900g/t silver and 26.00g/t gold over 1.30 metres, while the two new discoveries at Guanajuatito are highlighted by intersections of 1,010g/t silver and 6.67g/t gold over 1.10 metres and 1,460g/t silver and 4.79/t gold over 1.15 metres. A brief update on drilling at the Cata and Rayas Mines, also within the Guanajuato Mine Complex, is provided below.

"These are significant results in that they demonstrate our ability to make new discoveries at Guanajuato while continuing to expand the size and extent of the known mineralized zones," stated Robert Archer , CEO of Great Panther Silver. "Furthermore, the Valenciana drilling indicates that there is still un-mined high grade silver-gold mineralization in this historic mine that is worthy of follow up."

Valenciana Mine

In the Valenciana Mine area, remnants of old stope walls and pillars intersected in drilling above the 390 metre level include 7.45 metres grading 275g/t silver and 2.47g/t gold in UGV12-039, 1.10 metres grading 299g/t silver and 3.66g/t gold in UGV12-050, and 1.30 metres grading 2,900g/t silver and 26.00g/t gold in UGV12-051.

Drilling below the 390 metre level has intersected new mineralization including 3.10 metres grading 624g/t silver and 4.59g/t gold in UGV12-012.

The pillars and hanging wall and footwall stope walls are being tested mainly from drill stations on a new footwall ramp connecting the 320 Cata level (southeast side of the Valenciana deposit) to the 245 Valenciana level (northwest side of the Valenciana deposit).

Drilling in 2013 will continue to test the old Valenciana Mine area that extends approximately 400 metres along strike and 280 metres on the dip (click here to view Valenciana longitudinal section).

Guanajuatito Mine

Drilling in the Guanajuatito area, in the northwest part of the Mine Complex, has intersected mineralization both to the northwest (GTTO NW), and to the southeast (GTTO SE) of the existing development, between the 100 and 245 metre levels. The GTTO NW zone is approximately 50 metres in strike length, 140 metres down the dip, and open to depth and upward. The GTTO SE zone is approximately 50 metres along strike, 70 metres down the dip, and open to depth.

Highlights of the drilling in the GTTO NW zone include 2.25 metres grading 380g/t silver and 1.28g/t gold in UGG12-057, and 1.10 metres grading 1,010g/t silver and 6.67g/t gold in UGG12-061 (within a wider interval grading 285g/t silver and 2.61g/t gold over 4.40 metres). Drilling in the GTTO SE zone was highlighted by an intercept of 1.15 metres grading 1,460g/t silver and 4.79/t gold in UGG12-070.

Current development in the Guanajuatito Mine is at the 245 metre level, and this has been connected to the old 245 metre level of the Valenciana Mine (click here to view Guanajuatito longitudinal section), which gives access to the northwest edge of the Valenciana silver-gold deposit. Initial mapping and sampling southeast of the GTTO SE zone, along the old 245 metre level, shows a similar style of structural control and mineralization such that other in-situ zones may be located towards Valenciana.

With the aforementioned footwall ramp at Valenciana connecting to the 320 metre level at Cata, ore from Guanajuatito can now be transported underground to the Cata shaft, thereby eliminating the need for truck hauling to surface and then on surface to the Cata mill. This underground haulage is faster, cheaper and reduces truck traffic through populated parts of the City of Guanajuato.

Cata Mine

At the Cata Mine, exploration drilling is ongoing following the Veta Madre and hanging wall zones to the northwest and to depth. Mine development has progressed down to the 520 metre level, with stoping on the 520 and 490 metre levels. A drill program started in the fourth quarter of 2012 has had positive results extending mineralization to the northwest between the 470 and 520 metre levels on the Veta Madre and Contact Vein, and nine associated structures. Highlights of the drilling in the Cata Mine include 2.85 metres grading 318g/t silver and 0.4g/t gold in UGC12-043.

In 2013, drilling will test the depth extent of this mineralization (click here to view Cata Mine, Veta Madre longitudinal section).

Rayas Mine

On the Santa Margarita Vein in the Rayas Mine, fill in drilling continues, as does ramping down past the 500 metre level. Mining is presently ongoing on the 454 and 475 metre levels. Further areas for exploration drilling along the Veta Madre at Rayas in 2013 will include San Cayetano, Los Pozos, San Telesforo, and Promontorio.

Robert F. Brown , P. Eng. and Vice President of Exploration for the Company is the Qualified Person for the Guanajuato Mine Complex, under the meaning of NI 43-101. A full QA/QC program is being followed including the regular insertion of splits, blanks, and standards into the core sampling sequence. Analysis of the drill core samples was conducted at the Guanajuato Mine on-site laboratory, independently operated by SGS.
