Marketwired Canada
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.
