Great Panther drills 0.35 m of 1,950 g/t Ag at Topia 2008-02-19 16:26 ET - News Release Mr. Robert Archer reports GREAT PANTHER EXTENDS SILVER-GOLD-LEAD-ZINC VEINS AT THE TOPIA MINE Great Panther Resources Ltd.'s continuing drilling from surface and underground at the company's 100-per-cent-owned Topia mine in Durango, Mexico, continues to extend high-grade silver, gold, lead and zinc mineralization along strike, and to depth, on several of the veins that are currently being mined. Surface drilling throughout the last two quarters of 2007 tested the downdip and strike extensions of six veins. Highlights include downdip drilling on the Cantarranas vein, in hole ST07-061, which intersected 1,950 grams per tonne silver, 1.7 g/t gold, 2.7 per cent lead and 3.01 per cent zinc over 0.35 metre; and the strike extension of the Madre vein, in hole ST07-044, which intersected 502 g/t silver, 3.78 g/t gold, 3.91 per cent lead and 5.47 per cent zinc over 0.40 m. Underground drilling in the fourth quarter of 2007 focused on the rediscovered Don Benito vein and was highlighted by an intersection of 749 g/t silver, 5.67 g/t gold, 3.71 per cent lead and 4.96 per cent zinc over 1.27 m, in hole UT07-011, including a higher-grade portion of 1,400 g/t silver, 6.84 g/t gold, 4.54 per cent lead and 3.43 per cent zinc over 0.55 m. Holes UT07-010 to 013 (results compiled in the table) were all drilled from the same site along the Dos Amigos ramp area, at approximately the 1,500-level in a fan section, and intersected both the La Dura and the Don Benito veins (see maps on the company website). Note: Mine levels are named according to their elevation above mean sea level and the town of Topia sits at an elevation of 1,650 metres, such that most mine levels are accessed through adits from the sides of the mountains.

Development to the east, along 40 m of strike, returned 276 g/t silver, 0.39 g/t gold, 4.32 per cent lead and 2.69 per cent zinc, with an average width of 0.61 m. Development to the west along 28 m of strike returned 105 g/t silver, 0.82 g/t gold, 0.84 per cent lead and 2.48 per cent zinc over an average width of 0.49 m. Development along the vein is continuing. From a review of historic maps and remapping of old workings, the Don Benito vein is open from the 1,585 level, upward to at least the 1,700 level, and, considering the recent underground drilling along Don Benito from the 1,500 level, it is open downward to at least the 1,450 level. This implies a vertical extent of at least 250 m. The known strike extent of Don Benito is approximately 300 to 350 m. Underground drilling is continuing on the 1,500 level and, this month, several surface drill holes will test the Don Benito vein between the 1,585 and 1,700 levels. Underground development and exploitation are presently taking place on eight mineralized vein structures on the Topia mine property. This includes initial development along the Don Benito vein, continued development along the Recompensa, Argentina, Madre, Cantarranas, La Dura and Animas veins, and commencement of development along the San Gregorio vein. Surface drilling during the second half of 2007 tested the dip and strike extent of the Madre, La Dura, Animas, Cantarranas and Oliva veins. During 2007, a total of 33 surface holes were completed, totalling 7,422 metres. All of the surface and underground holes presented herein will be included in the new resource report being prepared by Wardrop Engineering, and expected in March. In the eastern portion of the Perla area, on the Madre vein, five surface holes were completed to test the dip and strike extension of mineralization toward the Carrizo fault. Drill hole ST07-044 intersected 502 g/t silver, 3.78 g/t gold, 3.91 per cent lead and 5.47 per cent zinc over 0.40 m, while ST07-040 intersected 149 g/t silver, 5.08 g/t gold, 2.6 per cent lead and 0.8 per cent zinc over 0.6 m. The deeper holes, ST07-045 to 047, intersected the Madre vein, but with modest gold, and lower silver, lead and zinc values. The downdip extension of the Cantarranas vein was tested in the Jicara area. Two holes were drilled with ST07-061 intersecting 1,950 g/t silver, 1.7 g/t gold, 2.7 per cent lead and 3.01 per cent zinc over 0.35 m, while the more easterly ST07-062 intersected an old stope. Further drilling is planned for 2008, as access is facilitated by the use of a short ramp from existing infrastructure. Three holes were drilled to test the downdip extension of the La Dura vein below the 1,585 level. The drill holes reflect the grade of the underground development in this area, with the best results from ST07-042, which returned 307 g/t silver, 1.88 g/t gold, 0.13 per cent lead and 0.48 per cent zinc over 0.3 m. Farther west along the La Dura vein, in the Dos Amigos area, holes ST07-056 and 057 intersected the La Dura vein at about the 1,400 level, and also discovered a new vein named the La Dura Alta. The best results are from ST07-057, where the La Dura Alta vein returned 1,040 g/t silver, 2.27 g/t gold, 0.3 per cent lead and 0.5 per cent zinc over 0.2 m, and the La Dura vein returned 39 g/t silver, 5.25 g/t gold, 0.3 per cent lead and 0.35 per cent zinc over 0.35 m. Underground development and exploitation in this area are continuing from the 1,420-level and 1,500-level ramp. Both the surface and underground drilling in the western part of the Topia district continue to demonstrate higher gold grades, in addition to silver, lead and zinc. Given the typically narrow veins at Topia, the higher gold content makes a significant contribution to the value of the mineralization. Highlights of the recent surface drilling are summarized in the table, and a plan map of veins and mine areas can be found on the company website. Presently the surface drilling is testing both the Santa Cruz and Argentina veins in the northern part of the district, and underground development is also continuing in this area. Following this, the surface drill will test the Cantarranas vein in the Jicara area, following up on ST07-061, and will further test the Don Benito vein. Results of this drilling will be reported when assay data are compiled.

Analysis of the aforementioned drill core was performed by SGS Minerals Services, in its Durango, Mexico, facilities. The company's quality assurance/quality control program includes the regular insertion of blanks, duplicates and standards into the sample shipments. Aspects of the Topia mine relating to mining and metallurgy are overseen by Charles Brown, chief operating officer for Great Panther, and its wholly owned Mexican subsidiary, Minera Mexicana El Rosario SA de CV (MMR). Robert F. Brown, PEng, vice-president of exploration for Great Panther, 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. |
