Great Panther Receives First Revenues from Topia Silver-Lead-Zinc Mine; Expands Development on Dos Amigos Vein System

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 15, 2006) - GREAT PANTHER RESOURCES LIMITED (TSX VENTURE:GPR) is pleased to announce that it has reached another significant milestone in its development as a primary silver producer with the receipt of its first revenues from the sale of concentrates from the Topia Mine in Durango, Mexico. Meanwhile development at the Mine is continuing with the exposure of high grade silver-lead-zinc mineralization on the Dos Amigos Vein.

Great Panther's Mexican subsidiary has now received three payments totaling US$684,110 from Penoles' smelter in Torreon. These amounts represent the 80% advanced payments, based upon the grade of the concentrate shipments. The balance of revenues due is paid out following processing and deduction of smelter charges. Throughput at the plant is presently being maintained at roughly 120 tonnes per day while mine development is advanced. The Topia Mine has a production target of 200 tonnes per day by the third quarter of this year.

Mine development is continuing along the Dos Amigos Vein system, which lies partly on the newly acquired Arco Iris concession. New sampling of this vein from the east end of the ramp has returned average grades of 924 g/t Ag, 21.78% Pb and 16.16% Zn along a 30 metre strike length. Although the vein has an average width of only 0.21 metres along this length, the Company is using a mining method called 'resuing' which reduces dilution & maximizes the grade of the material being recovered. (The aforementioned assays were obtained from the Company's onsite laboratory, which, although not certified, has shown good correlation with check assays in previous sampling. The lab presently does not have the ability to assay for gold. Check samples have been taken of this material and sent to ALS Chemex for verification. Any significant discrepancy in results will be reported.)

Along strike of this high grade mineralization, to the northeast, lie the old La Dura Mine workings that are also part of Great Panther's property. Recent sampling from the Dos Amigos Vein at the southwest end of La Dura has returned 475 g/t Ag, 1.01 g/t Au, 3.92% Pb and 5.09% Zn over a strike length of 89 metres and an average width of 0.36 metres. Slightly lower grade mineralization continues for another 108 metres to the northeast, returning average grades of 265 g/t Ag, 1.19 g/t Au, 0.62% Pb and 1.21% Zn over an average width of 0.52 metres. The aforementioned assays were obtained from SGS Labs.

There has been no underground development for approximately 200 metres between the southwest end of the La Dura Mine and the ramp mentioned above so the potential to find more high grade mineralization is excellent. Collectively, the aforementioned results represent more than 750 metres of strike length along the Dos Amigos Vein and the mineralization is open to depth along this entire distance. Continuing development on this vein system will include stations for an underground drill program, which will enable the Company to more easily and quickly determine the overall potential of the vein and to delineate a new resource that can be added to the mine plan.

Aspects of the Topia Mine relating to mining and metallurgy are overseen by Ing. Francisco Ramos Sanchez, Vice-President of Operations for Great Panther and its 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 the Topia Project under the meaning of NI 43-101, and has reviewed this news release.
