VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Dec. 12, 2006) - GREAT PANTHER RESOURCES LIMITED (TSX:GPR) is pleased to announce that surface diamond drilling has provided further definition of a new zone of silver-gold mineralization at the Company's wholly-owned Guanajuato Mine in Guanajuato, Mexico. This phase of the 2006 drill program comprised 1,011 metres in seven holes and was focused on an unexplored area along strike from the southeasternmost mine workings at the Garapata / Promontorio shafts. It represents a section of the Veta Madre vein structure approximately 150 metres in strike length by 150 metres vertical, immediately below surface and accessible by the San Vicente South Ramp. As such, the newly defined mineralization presents an immediate target for stope development and mining.
While all seven holes in the Garapata / Promontorio drilling intersected silver-gold mineralization, the most significant results include 149g/t silver and 2.2g/t gold across 5.4 metres of the Veta Madre in hole GTT-06-031; and 141g/t Ag and 0.54g/t Au across 2.24 metres of the Veta Madre in GTT-06-034, located 40 metres northwest of hole 31. Another 120m northwest of GTT-06-034, near the Promontorio shaft, GTT-06-028 intersected 92g/t Ag and1.08g/t Au across 3.65 metres.
Parallel zones to the Veta Madre are also well developed, including a hanging wall silica stockwork developed in conglomerate. Apparently, this zone was partially exploited in the past as holes GTT-06-030 and 032 were unexpectedly lost in unrecorded stopes. However, the remaining hangingwall stockwork in GTT-06-032 assayed 43g/t Ag and 0.95g/t Au across 4.9 metres.
Of particular note is that a footwall stockwork is locally developed in the porphyritic diorite. This new zone has been traced for approximately 150m of strike length with notable intersections of 92g/t Ag and 0.53g/t Au across 4.3 metres in GTT06-028 and 197g/t Ag and 0.57g/t Au across 1.52 metres in GTT-06-034.

Additional holes in the Garapata / Promontorio area will be completed by the underground drill commencing in early 2007.
The styles of mineralization at Garapata / Promontorio, as seen in the surface drilling and surface outcroppings, include silver-gold mineralization hosted in several quartz-carbonate stockwork zones in the hanging wall conglomerate; silica breccia in the Veta Madre located along the contact between the hangingwall conglomerate and footwall diorite porphyry; and in silica flooded (stockwork and breccia) footwall diorite. Detailed geological mapping and rock sampling of underground workings in this part of the mine are scheduled for Q1, 2007.
This phase of surface diamond drilling at Guanajuato brings the 2006 total to 6,753 metres in 34 holes. The program was highly successful in identifying and delineating three new zones of silver-gold mineralization in the northwest, central and southeast parts of the mine property. These discoveries accentuate the previous lack of exploration on the property and the potential for new zones to be found throughout the mine. In addition, the easy access to these zones from existing underground workings means that they can be developed and mined quickly and cost-effectively.
Samples were assayed at SGS Labs in Durango and diamond drilling was contracted to BDW Drilling Mexico, of Guadalajara. Robert F. Brown, P.Eng and Vice President of Exploration for the Company is the Qualified Person for the Guanajuato Mine Project, under the meaning of NI43-101, and has reviewed these results. The Company's QA/QC program includes the regular insertion of blanks, duplicates and standards into the sample shipments.
Great Panther owns a 100% interest in the Guanajuato Mine Complex. Historically, the Guanajuato Mine was one of the largest silver producers in Mexico and encompasses the core of the Guanajuato District, which has produced 1.2 billion ounces of silver and 4.5 million ounces gold.
