Monday March 31, 8:00 am ET


VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 31, 2008) - Orko Silver Corp. (TSX VENTURE:OK - News) 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 BP06-71 was performed in late 2007, from 251 metres to a new depth of 533 metres, and the extended hole name was changed to BP06-71ext. The Martha Vein was intersected at a depth of 389.43 to 411.62 metres for a true width of 20.85 metres grading gold 0.414 g/t and silver 433.5 g/t, for a silver-equivalent of 458.3 g/t. Within this interval is a true width 3.05 metres grading gold 0.802 g/t and silver 1,547.4 g/t, for a silver equivalent of 1,595.5 g/t.

Hole BP06-71ext 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 estimate.

In addition, the extended holes BP06-74ext, BP06-70ext, BP06-64ext, BP06-62ext and BP06-60ext also intersected the Martha Vein (see tables below).

Gary Cope, President of Orko, adds, "We are obviously very pleased with the intercept reported in Hole 71ext and the impact it will have on our upcoming 43-101 compliant Resource Estimate. Moreover, drilling is continuing at a brisk pace at La Preciosa with all four rigs working at full capacity and Hole 220 is now underway. Even with the inclusion of all currently available assay results in the next Resource Estimate, the Company will have drilled over 70 holes that will not be included in the upcoming Resource Estimate. We are eagerly looking forward to reporting the next Resource Estimate and beyond that foresee a continued stream of assay results from on-going drilling at La Preciosa."

Hole BP06-62 was drilled in 2006 east of the outcropping Abundancia Vein in the "Mina La Preciosa Sector", on section mine-grid 15,200 N, to test the Luz Elena vein. In late 2007 the hole was extended to a depth of 480.06 metres to test the Martha vein. The Martha vein is a network of veins and veinlets in this hole.

Hole BP06-60ext is located in the "Mina La Preciosa Sector", high on La Preciosa Ridge, on section mine-grid 15,200 N, east of holes BP05-03, 04 and 07, and west of hole BP06-62 and 64. Orientation was azimuth 090 degrees and dip -80 degrees. It was designed to pass through Abundancia vein, targeting the Luz Elena vein when initially drilled in 2006 and was extended deeper in late 2007 to intercept Martha vein, with the end of hole to 517.25 metres. Martha structure is present, with elevated base metal and gold values, but is low in silver.
