Orko Silver Hits Massive Intercept on Martha Vein

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 27, 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.

A deepening of hole BP06-75 was performed in late 2007, from 250 metres to a new depth of 521 metres, and the extended hole name was changed to BP06-75ext. The Martha Vein was intersected at a depth of 351.22 to 393.42 metres for a true width of 39.66 metres grading gold 0.370 g/t and silver 235.2 g/t, for a silver-equivalent of 257.5 g/t.

Hole BP06-75ext is located southeast of and adjacent to the area reported in the 43-101 compliant Resource Estimate (news release 01 October 2007) for the Martha Vein, thus will be included in the next resource estimate.

Gary Cope, President of Orko, adds, "The massive intercept announced in the extension of Hole 75 is certainly amongst the best to date at La Preciosa. Also of particular interest is an unnamed intercept in Hole 147 over 3.82 metres true width grading 643.3 g/t silver-equivalent encountered approximately 140 metres below the Martha Vein. As this could be the discovery of a new vein, future drilling will be designed to further test this new development. The Company anticipates releasing its next 43-101 compliant resource estimate before the end of March 2008."

The following tables highlight results from drilling targeted to intercept the Martha Vein and other veins.
