Orko Silver Hits 25.59 Metres Grading 222.3 g/t Silver-Equivalent on Martha Vein

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 28, 2008) - Orko Silver Corp. (TSX VENTURE: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.

Gary Cope, President of Orko, adds, "The Martha Vein continues to yield excellent grades across exceptionally wide intercepts. The strike length of the Martha structure is growing to the south east and current drilling is focused towards that direction. We are currently drilling holes 236-240 and we now have 85-90 holes drilled that were not in the last resource estimate. This, along with the significant intercepts from yet unnamed veins gives me cause for great optimism about the Company's future."

Of particular significance is an unnamed flat-lying vein which is hosted in andesite. This new vein, yet to be named, makes grade and thickness in this hole at 6.41 metres true width grading gold 0.401 g/t and silver 191.3 g/t for a silver-equivalent of 215.4 g/t. Martha is a vein and veinlets structure near the conglomerate/schist contact. Base metals are elevated in Martha at Zn 0.72 % and Pb 0.37 %.

Hole BP07-151 is located east of La Preciosa Ridge on mine section 14,900 N, drilled from the same pad as BP06-70ext and BP07-153. It is oriented azimuth 090, dip -75 degrees. Martha vein in this location is a weak structure in conglomerates and does not make grade. Base metal values are higher in the lower portion of the hole.

Of particular note is the emergence of a structure below Luz Elena vein and above Martha vein. This new vein, yet to be named, makes grade and thickness in this hole at 6.10 metres true width grading gold 0.057 g/t and silver 145.4 g/t for a silver-equivalent of 148.8 g/t. The central core of this vein is 3.07 metres true width grading gold 0.073 g/t and silver 250.3 g/t, for a silver-equivalent of 254.7 g/t.
