Great Panther Silver Announces Results Of San Ignacio Surface Drilling

December 16, 2013

GREAT PANTHER SILVER LIMITED (TSX: GPR) (NYSE MKT: GPL) ("Great Panther"; the "Company") today announced surface drilling results from its 100% owned San Ignacio Project in Guanajuato, Mexico. San Ignacio is currently in development with production expected to commence in the first half of 2014. The surface drilling comprised 13 holes totaling 1,144 metres and was focused on the upper 80 metres of the Intermediate Vein in order to define the top of the epithermal system and to better guide the first two years of development.

The most significant intersection of the program assayed 263g/t silver ("Ag") and 7.27g/t gold ("Au") over a core length of 24.60m (15.81m true width) in drill hole ESI13-106, on section 475N (see table below and updated longitudinal section on the Company's website at www.greatpanther.com).

The 2013 drill program filled in gaps from the 2011/2012 drill program and the new intersections corroborate the previous interpretation of the Intermediate Vein. The aforementioned intersection of thick vein mineralization in ESI13-106 correlates with previous drill results from hole ESI11-039, 25m to the south, that returned 185g/t Ag and 5.47g/t Au over a true width of 5.39m indicating that higher grade "blow-outs" or "clavos" are a natural part of the vein system.

As disclosed in the NI 43-101 report for the San Ignacio Project (see Company news release dated May 9, 2012), the Intermediate Vein currently hosts an Inferred Mineral Resource of 330,000 tonnes grading 144g/t silver and 2.71g/t gold, for a contained 3,274,000 silver equivalent ounces ("Ag eq oz"). This was part of a larger Inferred mineral resource estimate for the Intermediate, Melladito, Nombre de Dios and Nombre de Dios II zones totaling 826,000 tonnes grading 121g/t silver and 2.28g/t gold, for a contained 6,894,000 Ag eq oz.

A proposed drill program for the San Ignacio project in 2014 will include in-fill drilling deeper in the system and detailed drilling for 250 metres south along the Intermediate Vein in an area of limited exploitation dating back to the 19th century, as well as property-wide targeting.

  2) ESI13-112 intersected a void from 75-78m.
  3) ESI13-116 intersected a void from 86.3-88.15m.

The access ramp is progressing on schedule, with more than 100 metres constructed to date (310m planned). Once the Intermediate Vein is accessed, underground bulk sampling will allow for a full scale metallurgical evaluation at the Company's Cata plant, which will determine whether the San Ignacio mineralization should be blended with the ore produced from the Company's Guanajuato Mine Complex or processed separately.

The offices, change rooms, water and communication facilities at the historical San Ignacio Mine Site have already been re-established and ancillary surface infrastructure including an electrical substation and workshop for mechanical services are under construction. All necessary equipment and project personnel for the initial mine development have been sourced from the main Guanajuato mine. The use of existing equipment, and the proximity of the resource to the surface, will minimize capital and development expenditures for San Ignacio.

Production from San Ignacio is anticipated to start in the first half of 2014 at about 100 tonnes per day and will be ramped up to about 250 tonnes per day by the end of 2014. The ore will be trucked 22 kilometres to the Cata plant at the Guanajuato Mine Complex for processing.

Robert F. Brown , P. Eng. and Vice President of Exploration for the Company, is the Qualified Person for the San Ignacio Project and has reviewed these results. The Company's QA/QC program includes the regular insertion of blanks, duplicates, and standards into the sample shipments.
