Orko Silver Hits 16.55 Metres Grading 377.7 g/t Silver-Equivalent on Martha Vein

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 19, 2007) - 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.

Ten more drill holes have extended the Martha Vein structure from the previously reported Inferred Resource Estimate area (see news release 01 October 2007), of which seven exceed 5 metres true width, illustrating the continuity of this major structure. Hole BP07-135 hit a true width of 16.55 metres grading gold 0.363 g/t, silver 355.9 g/t for a silver-equivalent of 377.7 g/t.

Gary Cope, President of Orko, adds, "Since the last resource estimate that included holes to BP07-120, the focus of the ongoing drilling program has been to drill test the Martha Vein both to the east and to the south of the previously defined area of Martha Vein resource reported in the Oct 1 resource estimate (see news release Oct 1, 2007 for details). To date the company has drilled approximately 35 holes further testing the extent of the Martha Vein which now has been intercepted continuously in numerous holes up to a further kilometer south and east of the holes that contain the Martha Vein mineral resource estimate. The Martha Vein is an encouraging structure, varying in thickness but consistent in predictability as the drills move east and south of the previous Martha resource estimates. Grades for many of the Martha vein holes recently drilled are unknown and will be released as the company receives the results of the sampling.

The discovery of Martha and the newly available drilling data suggests that we are onto a deposit of much larger scale and scope than had originally been conceived. To that end, we are focusing our attention and resources on drill testing the Martha Vein more aggressively. We are proud of what our team has accomplished at La Preciosa and are excited about the prospect of releasing more drill results. We look forward to releasing new resource estimate in Q1 2008."

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