Great Panther Starts Commissioning of Plant at Guanajuato

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 28, 2006) - GREAT PANTHER RESOURCES LIMITED (TSX VENTURE:GPR) is pleased to announce that it has initiated the commissioning of the processing plant at its Guanajuato Silver-Gold Mine in Guanajuato, Mexico. The 1,200 tonne per day plant has been undergoing extensive refurbishing for the past 3 months as Great Panther prepares to place the mine back into production.

The commissioning of the crushing, milling and flotation equipment involves systematic testing of all components of the circuits from both a mechanical and metallurgical standpoint. This process is anticipated to take about 3-4 weeks to complete and will allow the Company to optimize the efficiency of the plant and maximize recoveries of silver and gold in the concentrate.

Metallurgical tests will be conducted on different types of mineralization in order to determine if the flotation system used in the past is really the best recovery process to be used. The Company is examining the possibility of modifying the recovery process such that silver-gold dore could be poured on site.

Under the previous owners, the plant last operated at full capacity in 1991 and the throughput had fallen to about 20% (approximately 250 tonnes per day) by 2005 due to a lack of working capital. As there are three ball mills in the plant, each with a capacity of 400 tonnes per day, the Company plans to bring them on stream one at a time, with a goal of reaching the full capacity of 1,200 tonnes per day by the end of 2006. As a smelter contract for Guanajuato was finalized at the same time as the contract for Great Panther's Topia Mine, there will be no delay in shipping concentrates once production begins.

In anticipation of the start-up of the plant, resources are being better defined through detailed sampling, and an underground drilling program is scheduled to begin within a few weeks. As this work progresses, the new resource base will be made compliant with NI 43-101 (first report anticipated by Q4 2006). Historical mine data is being brought into a digital format and a 3D model is being created to assist in mine planning and target selection.

Historically, the Guanajuato District was the third largest silver producer in Mexico, with past production estimated at 1.2 billion ounces of silver and 4.5 million ounces gold. Great Panther's Guanajuato Mine Complex encompasses more than 4 kilometres of strike length on the core of this prolific silver-gold camp.

Aspects of the Guanajuato 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 Guanajuato Project under the meaning of NI 43-101, and has reviewed this news release.
