Orko Silver Announces Two Major Developments at La Preciosa

Orko Silver Corp. (TSX VENTURE:OK - News) is pleased to announce that it has received further assay results from the current diamond drilling program in the “Mina La Preciosa” and “La Preciosa Norte” sectors on La Preciosa Project in Durango, Mexico.

1) Orko Silver Drills 3.92 m of greater than One Kilogram/tonne Silver Equivalent

Of particular note is a new substantial width and grade intercept of the Abundancia Vein in “La Preciosa Norte” sector in hole BP06-78. It yielded 6.45 metres true width grading 640.6 g/t Ag and 1.101 g/t Au, for a Silver-Equivalent of 706.7 g/t including 3.92 metres true width grading 981.3 g/t Ag and 1.585g/t Au for a Silver-Equivalent of 1,076.4 g/t. This sector was not included in the previously released Inferred Resource Estimate (13 March 2007).

2) Orko Silver Discovers Major New Vein Approaching 10 metres True Width

Mina La Preciosa Sector

The Company is also pleased to report that multiple new veins at depth have been intersected in BP06-77, including one, now named the Martha Vein, with a major thickness of 9.97 metres true width grading gold 0.339 g/t and silver 249.5 g/t for a silver-equivalent of 269.8 g/t. This discovery will alter future drill hole planning for deeper holes.

Hole BP06-77 was drilled from the northern side of La Preciosa Ridge, azimuth 090 degrees, dip -45 degrees, on mine-section 15,400 N.

Gary Cope, President of Orko, adds, “The increasing grade and thickness of the intercept in the Abundancia Vein and the discovery of a major new vein with a true width approaching 10 meters coupled with substantial grade represent major steps forward at La Preciosa for Orko Silver. These new results were not included in our recently released 43-101 compliant Inferred Resource Estimate which only included results up to hole 76. Given that we are currently drilling holes 105 and 106, we anticipate adding the results of at least 30 additional holes in our next resource estimate. These new developments only serve to increase our confidence level that our minimum goal at La Preciosa will be achieved.”
