GPR - Great Panther extends Gold-rich Zones with Surface Drilling at Topia Mine

April 04, 2007
GREAT PANTHER RESOURCES LIMITED (TSX: GPR) is pleased to announce that surface drilling in portions of the Animas vein at the Company's 100% owned Topia Silver-Lead-Zinc Mine in Durango, Mexico is continuing to demonstrate good gold grades. The best intersection in this phase of the program, from hole ST07-36, returned 2.58 g/t Au over 2.50 metres, while individual samples in other holes returned assays up to 12.70 g/t Au.

Current mining on the Animas vein is being conducted on three levels, 1420, 1430, and 1550 (note that levels are named according to metres above mean sea level, so level 1550 is 130m higher than level 1420). Underground sampling from levels 1430 down to 1380 showing excellent gold grades was reported on October 12, 2006 and the surface drilling is designed to test the vein along strike and to depth. Drill holes ST06-030, 031, and 032 targeted the Animas vein east of the 1430 workings, and below the 1550 level. All three holes were successful, with the best intersection in ST06-032 of 2.43g/t gold, 315g/t silver, 0.9% lead, and 9.0% zinc over 0.4m (see summary of results in the table below, and on the Company's web-site for drill hole location map). Drill hole ST06-033 was a test of the Animas vein at depth, and intersected the vein at approximately the 1300 metre level, well below existing workings, with 2.85 g/t gold and 42.9 g/t silver over 0.55m.

Approximately 350 metres along strike to the east of these holes, ST07-034 and 035 intersected the Animas vein at the 1400 level in a previously untested area, returning low grade values in both drill holes. A further 200 metres east, hole ST07-036 intersected a silicified breccia zone returning 2.58g/t gold over 2.50 metres, as mentioned above. This brecciation likely occurs along the Animas vein structure, and will be further drill tested, both for the extent of the brecciation, and veining.

Hole ST07-037 was drilled east of a major fault and no recognizable structures were identified. ST07-038 did not reach its primary target, the Veta Madre, but did intersect a parallel, although very narrow (0.08m) structure, potentially the Hipolito vein, which returned 0.57g/t gold, 1080g/t silver, 2.8% lead, and 1.1% zinc. Due to the high silver grade of this vein, it will be tested farther along strike to see if it widens out.

In addition to the Animas vein drilling, the eastern and depth extent of the Veta Madre was targeted by two holes. Hole ST07-039 was lost due to bad ground but ST07-040 intersected the Veta Madre, returning 5.08g/t gold, 149g/t silver, 2.6% lead and 0.8% zinc over 0.6m. Follow up drilling is planned around this intersection.

The ongoing surface drilling program at Topia, in conjunction with the underground drilling, is designed to double the NI 43-101 resources by the end of the year. The first NI 43-101 resource for the mine, reported on December 28, 2006, contained 3,625,603 oz of Ag Equivalent in the Measured and Indicated categories and an Inferred Resource of 1,418,900 oz of Ag Equivalent.

Both the surface and underground drilling at Topia have been contracted to BDW Drilling of Guadalajara, Mexico. Analysis of the aforementioned drill core was performed by SGS Minerals Services, ISO 9001 Registered, in their Durango, Mexico facilities.

Aspects of the Topia Mine relating to mining and metallurgy are overseen by Ing. Francisco Ramos Sánchez, 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 the Topia Mine Project under the meaning of NI 43-101, and has reviewed this news release.
