VANCOUVER, British Columbia - Orko Silver Corp. (TSX.V - OK) is pleased to announce that it has received further assay results from its on-going diamond drilling program at La Preciosa Project in Durango, Mexico.

Of particular note in this release for the Martha Vein is hole BP08-212A, which yielded a true thickness of 8.16 metres grading gold 0.184 g/t and silver 247.9 g/t for a silver-equivalent of 258.9 g/t. Also, hole BP08-192 yielded 2.98 metres grading gold 0.435 g/t and silver 556.3 g/t for a silver-equivalent of 583.4 g/t.

Gary Cope, President of Orko, adds, "We are very pleased with this set of drill results and the overall success of our drilling program. Expanding the Martha Vein along strike and at depth is the focus of the current drilling program. The Martha Vein is relatively flat lying, averages 10m in true widths and is dipping an average of 20 degrees to the west. To date, the Martha Vein has been drill tested over a length of approximately two kilometers in a north-south direction and 800 metres in an east-west direction. The company's technical team sees the potential of an additional 3 kilometers of length for the Martha Vein structure to the south-east.

The latest resource estimate includes the results of 51 Martha drill holes which accounted for 56% of the overall resource (see News Release dated March 31, 2008). All of the over 130 holes not in the latest resource estimate have intercepted the Martha Vein structure. We look forward to releasing further results in the near future."

Hole BP07-170 is located east of La Preciosa Ridge on mine section 15,300 N, 116 metres east of hole BP07-132, on the same drill pad as hole BP07-149. It is oriented azimuth 090, dip -75 degrees. The lowest intercept is also high in base metals at Pb = 1.47 % and Zn = 15.23 %.

Most of the holes in the mid-170s, plus some in the 180s and 190s, are along the eastern margin of the main mineralized trend and, as expected, do not carry ore grades. This is the case for holes BP08-171, 173, 177, 185, 186 and 190. Hole BP08-175 was abandoned short of target due to drilling difficulties and has been replaced by Hole P08-207.
