Great Panther Increases Production at Mexican Silver Mines

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 23, 2006) - GREAT PANTHER RESOURCES LIMITED (TSX:GPR) is pleased to announce that production continues to increase at both of its 100% owned silver mines in Mexico. At the Topia Silver-Lead-Zinc Mine in Durango, the plant throughput has been increased from 120 to 160 tonnes per day with the commissioning of the second ball mill. Meanwhile, at the Guanajuato Mine Complex, the second ball mill has been operating intermittently as mill feed is gradually increased from the ongoing mine development. Total throughput at the Guanajuato plant has risen from 400 to 700 tonnes per day and will continue to increase into the New Year.

The third ball mill at Topia will be commissioned in early 2007 such that the plant capacity will continue to grow through next year. The original target of 200 tonnes per day should be attained in Q1 2007 with ultimate capacity anticipated to be in excess of 300 tonnes per day by late 2007/early 2008. The third mill at Guanajuato is currently being refurbished and it is anticipated that mine development will be sufficiently advanced by Q1 2007 to reach the full plant capacity of 1,200 tonnes per day later that quarter.

New underground development is also continuing at both mines. As announced on October 12, 2006, production from the Argentina vein at Topia is anticipated to begin in Q1 2007 and will build as high grade silver-lead-zinc mineralization is developed on multiple levels. At Guanajuato, new production has commenced from several stopes on the 345 level of the Rayas and Cata Mines, while mining continues in the San Vicente and Guanajuatito areas.

The 34-hole surface diamond drilling program has been completed at Guanajuato and final assay results from the Promontorio area near the southeast property boundary are pending. Drilling in the Guanajuatito and Animas areas have already identified significant silver-gold mineralization that is available for immediate development. All of the mineralized intercepts from the surface program at Guanajuato will be incorporated into the first NI43-101 compliant resource report, which is expected to be received in the first quarter of 2007.

A new, 5,000 metre surface drilling program, contracted to BDW Drilling of Mexico, has also begun at Topia. Previous surface drilling results, along with underground sampling, are being used to calculate the first NI43-101 compliant resource for the mine. Wardrop Engineering is expected to deliver this result to the Company within the next couple of weeks. In addition, Great Panther has purchased four new underground diamond drills - three for Guanajuato and one for Topia - that will be operated by the Company's own personnel rather than under contract. This should increase productivity in the definition of new resources at both of the mines.

Aspects of the Topia and Guanajuato Mines relating to mining and metallurgy are overseen by Ing. Francisco Ramos Sanchez, Vice-President of Operations for Great Panther and its wholly owned Mexican subsidiary, Minera Mexicana El Rosario, S.A. de C.V. (MMR). Robert F. Brown, P.Eng. and Vice-President of Exploration for Great Panther and MMR is designated as the Qualified Person for both mines under the meaning of NI 43-101, and has reviewed this news release.
