Great Panther Expands Near-Surface Silver-Gold Zones at Guanajuato

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 29, 2007) - GREAT PANTHER RESOURCES LIMITED (TSX:GPR) is pleased to announce further results from surface diamond drilling at the Company's wholly-owned Guanajuato Mine in Guanajuato, Mexico. The final holes of the 2007 surface program expanded the previously discovered mineralization in the Promontorio area with intercepts such as 12.5 metres of 3.79 g/t gold and 71 g/t silver plus 4.41 metres of 6.26 g/t gold and 256 g/t silver in SG07-065, as well as intersecting new extensions of historic zones near the Cata plant such as 7.10 metres of 1.10 g/t gold and 155 g/t silver in hole SG07-54.

This portion of the 2007 drill program comprised 5,274 metres in twenty-three holes (SG07-046 to SG07-068) and tested the near surface parts of the Veta Madre system near the Tepeyac Shaft (south of the historic Valenciana workings), the Maravillas Shaft (north of the historic Cata workings) and additional drilling in the Promontorio Shaft area following up on the recent discovery of new mineralized zones in that area (Great Panther news release July 9, 2007). A final tally of 7,408 metres of surface drilling has been completed in 2007 at Guanajuato in 34 holes.

While previous drilling in the Promontorio area showed that mineralization here comprises at least seven parallel zones - the main Veta Madre, a hangingwall zone ('HW' - above the Veta Madre) and five footwall zones ('FW' - below the Veta Madre) - the follow up drilling has indicated that some of these zones locally appear to coalesce into one large zone, or "clavo". This is best displayed in the aforementioned hole SG07-65 where sampling above and below an old stope on the Veta Madre returned 3.79 g/t gold and 71 g/t silver over 12.5 metres plus 6.26 g/t gold and 256 g/t silver over 4.41 metres, respectively immediately adjacent to the stope. As this hole was drilled somewhat obliquely to the orientation of the vein, the true width of the zone, including the mined out portion appears to be 9.79 metres. Other significant parts of the Veta Madre have been left in place as evidenced by the intersection of 2.25 g/t gold and 96 g/t silver over 5.75 metres in SG07-064.

Also following up on the last round of Promontorio drilling, additional assays were received from several of the previously drilled holes in this area and some of the mineralized zones were widened in the process. The best example of this is hole SG07-43 where 11.20 metres grading 2.83 g/t gold and 47 g/t silver was sampled adjacent to an old stope on the Veta Madre. The footwall side of the same stope assayed 2.39 g/t gold and 202 g/t silver over 3.55 metres (previously reported). As such, the true width of this zone, including the mined out portion, appears to be 9.54 metres, consistent with the 9.79 metre width observed in hole 65.

The HW zone at Promontorio was expanded southward in this program, and highlighted with intersections of 0.77 g/t gold and 216 g/t silver over 2.2 metres in SG07-059 and 2.14 g/t gold and 152 g/t silver over 8.34 metres in SG07-063. The FW zones were not significantly expanded in this program, however, and may be a local feature, possibly related to a dilational part of the Veta Madre structure. Additional intersections can be found in the table below.

Drill holes SG07-053 to 058, inclusive, tested the area close to the old Maravillas Shaft, just north of the plant at Cata. Results here were highlighted by the aforementioned 7.10 metres of 1.10 g/t gold and 155 g/t silver in hole SG07-54, while holes 53 and 55 returned similar grades over narrower intervals. The Tepeyac area did not return any significant results.

All of the mineralization intersected in the 2007 surface program lies between 70 and 160 metres vertically below surface. The Promontorio Zones represent approximately 150 metres of strike length and 200 metres of down-dip extension. They are accessible by ramp and existing underground workings are currently being re-habilitated. As soon as possible, detailed drilling to define and further extend the Promontorio area mineralization will be carried out from underground. Mineralization in the Maravillas area will be assessed by the mine staff to determine how best to develop this area.

Samples were assayed at SGS in Durango and diamond drilling was contracted to Canrock Drilling, of San Luis de Potosi. 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.
