Great Panther Commences Diamond Drilling at Km66 Property

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Dec. 18, 2006) - GREAT PANTHER RESOURCES LIMITED (TSX:GPR) is pleased to announce that a 5,000 metre diamond drilling program has commenced at the Company's Km 66 Project in northeastern Durango State, Mexico. The 3,508 hectare property hosts significant silver-lead-zinc-gold mineralization with excellent potential for a large bulk tonnage deposit.

Initially the drilling program will focus on infilling and confirming previous Coeur d'Alene drilling results (core and reverse circulation methods) in the Palmitas and La Gloria Zones. These two zones contain a NI 43-101 compliant inferred mineral resource of 5 million tons grading 58 g/t Ag, 0.81% Pb and 1.3% Zn at a 50 g/t cut off AgEQ cut-off (22.3 million ounces silver equivalent(1)), as recently estimated for Great Panther by Wardrop Engineering (news release September 11, 2006). One area to be tested will be between Coeur d'Alene core holes #6 and #11, spaced 80 metres apart in the western end of the Palmitas Zone. Drill hole #6 returned 36 metres averaging 66.9 g/t Ag, 0.24 g/t Au, 1.09% Pb, and 1.04% Zn; while hole #11 returned 29 metres averaging 51.0 g/t Ag, 0.19 g/t Au, 0.84% Pb, 0.54% Zn and a separate 33.4 metres averaging 104.6 g/t Ag, 0.13 g/t Au, 1.68% Pb, and 1.21% Zn.

Great Panther geologists have also been re-mapping the surface geology, re-sampling surface trenches and completing plans, sections and a 3D model of the above zones. The mineralization at Km 66 is associated with hydrothermal breccias and stockworks related to a cluster of rhyolite domes that intrude the Cretaceous Caracol Formation.

The diamond drilling program will be conducted by BDW Drilling of Guadalajara, Mexico. Robert F. Brown, P.Eng. and Vice-President of Exploration for Great Panther and its wholly owned subsidiary, Minera Mexicana El Rosario, S.A. de C.V., is designated as the Qualified Person for the Km 66 Project under the meaning of NI 43-101 and has reviewed this news release.

(1) 22.3 million ounces silver equivalent calculation formula from Wardrop Engineering is as follows: AgEQ equals ((Ag g/t/34.2857 X 0.76 X 6.95) + (Au g/t /34.2857 X 0.7 X 432) + (Pb% X 20 X 0.8 X 0.42) + (Zn% X 20 X 0.8 X0.63))/6.95 X 34.2857
