Orko Silver Corp. (TSX VENTURE: OK) is pleased to provide a
development update for La Preciosa, operated by our joint venture
partner, Pan American Silver Corp. (PAA) in Durango, Mexico.
Detailed and regional exploration drilling at La Preciosa has
continued with three diamond drill rigs on site. Regional
exploration has advanced, and two rigs have been mobilized to the
Nancy and Orito zones, with at total of 5,300 metres planned for
the two zones. In addition, a total of 8-12 holes have been planned
to test the northern extension of the "Martha" structure, all
guided by the recently completed 70 line-km magnetometer survey. An
additional 8-12 holes have also been planned to further test the
Baritina structure.
As of the end of May, Pan American has completed over 51,000
metres of diamond drilling at La Preciosa. Combined with Orko's
2005-2008 drilling of 154,000 metres, the project has now surpassed
the 200,000 metre mark. Results from Pan American's Phase-I,
Phase-II and the first part of the Phase -III were reported in news
releases dated September 08 and October 21, 2009 and April 29,
2010. The included information on this news release is in addition
to these earlier news releases.
This news release summarizes the results from a total of 12,178
metres of diamond drilling in 60 drill holes. Diamond drill hole
BP09-476, collared in the La Preciosa main resource area, yielded
46.78 metres true thickness grading Au 0.379 g/t and Ag 196.7 g/t
for a silver-equivalent of 219.4 g/t. Within this intercept is 3.89
metres grading Au 2.533 g/t and Ag 988.1 g/t for a
silver-equivalent of 1,140.1 g/t. The following table highlights
recent drilling results. A detailed listing of the drill results,
including the new holes reported since April 29 2010, can be found
on the company website at the link found near the end of this news
release.

Ongoing Site Engineering
A number of key Engineering firms have been added to the project
development team.
-- M3 Engineering (Arizona, USA), was awarded the contract for plant design
and infrastructure costing.
-- Quantitative Group (QG) Pty Ltd. (Australia) has been contracted to
perform a Geostatistical evaluation and to prepare a new resource model
for the project.
-- Golder Associates Ltd. (Canada) is conducting a geotechnical evaluation
of the veins and Pan American anticipates receiving a report detailing
their findings.
-- Delkor Inc. (Netherlands) has conducted Filtration testing.
-- An environmental consultant is being selected to perform environmental
baseline studies in the project area.
Gary Cope, President of Orko, states; "We are extremely pleased
to see that Pan American's ongoing exploration program has produced
encouraging grades in drilling, but has also outlined a number of
high priority exploration targets. La Preciosa is a project that
continues to develop as a key asset to both Orko Silver and Pan
American Silver"
The Q2-anticipated preliminary economic assessment (PEA) has
been delayed due to increased efforts in regional exploration as a
PEA would not fully encompass the most recent advances in
exploration. This delay will not affect the Feasibility study,
which is still anticipated in late Q4-2010.
The delineation drilling results from the new holes are mainly
located in the known Martha vein structure and were drilled at
approximately 18 metre and 50 metre centres in an area previously
drilled by Orko at 100 metre spacing. This data again confirms
Orko's previously reported results, and forms the basis of a
geostatistical study, toward ultimate reserve definition. Phase-III
diamond drilling is still underway.

Ben Whiting, P.Geo., is the Qualified Person for Orko Silver
Corp. and takes responsibility for the technical disclosure in this
news release.
Silver-equivalent for the purposes of this drilling program is
defined as silver grade plus 60 times gold grade. This 60:1 ratio
was determined from the ten-year average of gold and silver prices
from the London Metal Exchange. Metallurgical recoveries and net
smelter returns are assumed to be 100% for the silver-equivalent
value. Base metal values are not included in the
silver-equivalent.
About Orko Silver Corp.
Orko Silver Corp. is developing one of the world's largest
primary silver deposits, La Preciosa, located near the city of
Durango, in the State of Durango, Mexico.
