Orko Silver Expands the Martha Vein to the Southeast at La Preciosa

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 15, 2008) - Orko Silver Corp. (TSX VENTURE:OK) is pleased to announce that it has received further assay results from the current diamond drilling program on La Preciosa Project in Durango, Mexico.

Additional drilling has extended the Martha Vein southeastward; including a thick mineralized zone 400 metres south of the area reported in the October 1st, 2007, 43-101 Compliant Resource Estimate.

Hole BP07-146 hit a true width of 15.15 metres grading gold 0.321 g/t, silver 141.7 g/t for a silver-equivalent of 160.9 g/t. It includes a higher grade core of 8.20 metres grading gold 0.519 g/t, silver 213.3 g/t for a silver-equivalent of 244.5 g/t. This hole expands the area previously reported with hole BP07-135, which yielded 16.55 metres of gold 0.363 g/t and silver 355.9 g/t for a silver equivalent of 377.7 g/t (see news release dated November 19th, 2007).

Gary Cope, President of Orko Silver, adds, "These results continue to demonstrate that the Martha Vein is a major developing story at La Preciosa. The grades combined with large widths are very encouraging for our next 43-101 Resource Estimate expected to be released at the end of the first quarter. We are also happy to report that the 2008 Exploration program is now fully operational with all 4 rigs drilling at La Preciosa."

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