VANCOUVER, BRITISH COLUMBIA, Dec 03, 2013 (Menafn – Marketwired via COMTEX) –GREAT PANTHER SILVER LIMITED (nyse mkt:GPL) (“theCompany”) announces the completion of the updated mineral resourceestimates at the Company’s wholly-owned Guanajuato Mine Complex(“Guanajuato Mine”) in Guanajuato, Mexico. This update does notaffect the San Ignacio Inferred resource estimate, which remains asreported in 2012.



Updated Measured and Indicated (“M&I”) mineral resources at the
Guanajuato Mine Complex comprise 504,700 tonnes at a grade of 174g/t
silver (“Ag”) and 1.65g/t gold (“Au”), containing 4,430,000 silver
equivalent ounces (“Ag eq oz”), using a 50g/t silver equivalent (“Ag
eq”) cut-off;
Inferred mineral resources at the Guanajuato Mine Complex are estimated
to comprise 434,000 tonnes at a grade of 140g/t Ag and 2.32g/t Au,
containing 3,900,000 Ag eq oz. Different cut-off grades were used for
the seven mineralized zones as indicated in the table below.



“We are pleased that ongoing underground drilling and developmentcontinues to extend the mineralized zones in advance of production,”stated Robert Archer, President & CEO. “Although the M&I resourcedeclined from previous levels, the Inferred resource increasedsubstantially so we will be focusing our efforts on upgrading theseounces into the M&I category in 2014. The Inferred resource is basedstrictly upon drilling whereas the M&I resource also incorporatesmine development and underground sampling. As such, theclassification of a particular resource can often be a timing issuebased upon mine development schedules. What is important for anunderground operation like Guanajuato is that we are replacing ouncesas they are being mined, as a ‘rolling resource’.”


Results of the recently completed development along the Veta Madre onthe 525 metre level (lowest level) of the Cata Clavo included a 50metre strike length grading 794g/t silver and 1.85g/t gold across anaverage true width of 3.6 metres. Underground drilling continues toexplore the Veta Madre at Cata Clavo below the 525 level.


The 2013 Guanajuato Mine Complex mineral resource estimate containsMeasured and Indicated mineral resources of 4,430,000 Ag eq ozincluding 3,348,000 Ag eq oz in the Measured category and 1,081,000Ag eq oz in the Indicated category (see table below). Inferredmineral resources are estimated at 3,900,000 Ag eq oz. These arecontained in the Cata Clavo, Los Pozos, Santa Margarita, SanCayetano, Promontorio, Valenciana and Guanajuatito zones. TheGuanajuatito zone has been expanded with the addition of theNorthwest and Southeast zones (see Company news release datedFebruary 15, 2013), illustrating that additional mineralization isbeing found and added to inventory with systematic and focuseddrilling. A new zone, designated Los Pozos SE, has been added due tosuccessful exploration immediately southeast of the Los Pozos zone.Additionally, initial Inferred mineral resource estimates have beenadded for the San Cayetano (Rayas shaft area south of SantaMargarita), Valenciana, and Promontorio zones.


Overall, from the last mineral resource estimate (effective dateJanuary 31, 2012), the Measured and Indicated classificationdecreased 21.6% (-1,219,000 Ag eq oz), while the Inferred mineralresource increased 55.8% (1,397,000 Ag eq oz). Management iscommitted to maintaining or increasing mineral resources at theGuanajuato Mine, a commitment shown through focused drilling, andthrough better understanding of the complex structurally controlledmineralized zones.


Mining of four zones, namely Cata, Los Pozos, Santa Margarita andGuanajuatito, currently accounts for most of the Guanajuato metalproduction. This updated mineral resource will help in guidingdevelopment and with improving grades at the mines. Undergrounddrilling will resume in 2014 with three drill rigs to delineate newresources on the upper extensions of Los Pozos SE (Veta Madre) andSanta Margarita, and the down dip extensions of the Cata Clavo zones.


Development and exploration are ongoing to expand mineral resources1) along the Santa Margarita structure (hanging wall zone to VetaMadre) both to the southeast strike extension and between the 390 and270 levels (above present mining), 2) at Guanajuatito (Veta Madre anda footwall zone) both laterally (50-120 level) and in deep extensions(245-390 levels), 3) at Valenciana (Veta Madre and both footwall andhanging wall zones as well as exploration both at depth and proximalto old workings), 4) at San Cayetano (Veta Madre), 5) at Cata in theupper areas along strike both to the SE and NW, and 6) at Promontorio(Veta Madre and both footwall and hanging wall zones).


Through a collaborate effort, a Special Projects team from theCompany’s Geology, Mining, and Planning Departments is reviewing allpreviously mined areas for opportunities in further exploitation.This has been a particularly successful effort as new opportunitiescan be turned into “un-official” mineral resources and mined withinmonths due to existing access. Examples include the exploitation ofhigh grade material from an old Los Pozos stope above the 250 level,along with expansion of the stope itself, and the further definitionof mineralization presently being exploited on the Santa Margaritavein from the 390, 365, and 345 levels.


The updated mineral resource estimate for the Guanajuato Mine isvalid as of July 31, 2013. Block model graphics, maps, sections andprevious news releases can be viewed on the Company’s website atwww.greatpanther.com. The estimates were classified according to theCIM Definition Standards on Mineral Resources and Mineral Reservesand, as such, are consistent with the requirements of NI 43-101. Themineral resource estimate was completed by Linda Sprigg, RPGeo AIG,consultant mineral resource geologist for the Company and a QualifiedPerson (“Q.P.”), and Robert Brown, P.Eng., and Company Q.P.
