Orko Silver Hits 25.59 Metres Grading 222.3 g/t Silver-Equivalent on Martha Vein
April 28 2008 - 8:00AM
Marketwired Canada
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.
Gary Cope, President of Orko, adds, "The Martha Vein continues to yield
excellent grades across exceptionally wide intercepts. The strike length of the
Martha structure is growing to the south east and current drilling is focused
towards that direction. We are currently drilling holes 236-240 and we now have
85-90 holes drilled that were not in the last resource estimate. This, along
with the significant intercepts from yet unnamed veins gives me cause for great
optimism about the Company's future."

Hole BP07-154 is located east of La Preciosa Ridge on mine section 14,800 N, 100
metres east of BP06-67ext. It is oriented azimuth 000, dip -90 degrees. Of
particular significance is an unnamed flat-lying vein which is hosted in
andesite. This new vein, yet to be named, makes grade and thickness in this hole
at 6.41 metres true width grading gold 0.401 g/t and silver 191.3 g/t for a
silver-equivalent of 215.4 g/t. Martha is a vein and veinlets structure near the
conglomerate/schist contact. Base metals are elevated in Martha at Zn 0.72 % and
Pb 0.37 %.

Hole BP07-151 is located east of La Preciosa Ridge on mine section 14,900 N,
drilled from the same pad as BP06-70ext and BP07-153. It is oriented azimuth
090, dip -75 degrees. Martha vein in this location is a weak structure in
conglomerates and does not make grade. Base metal values are higher in the lower
portion of the hole.
Of particular note is the emergence of a structure below Luz Elena vein and
above Martha vein. This new vein, yet to be named, makes grade and thickness in
this hole at 6.10 metres true width grading gold 0.057 g/t and silver 145.4 g/t
for a silver-equivalent of 148.8 g/t. The central core of this vein is 3.07
metres true width grading gold 0.073 g/t and silver 250.3 g/t, for a
silver-equivalent of 254.7 g/t.
