Orko Silver Corp. (TSX VENTURE:OK) is pleased to announce that it has received
results from the first laboratory testing program to investigate the mineral
processing characteristics of the La Preciosa silver deposit. The results
indicate that metallurgical recovery of silver from the La Preciosa silver
deposit will approach 90%.


Gary Hawthorn, P. Eng, President of Westcoast Mineral Testing Inc. adds, "These
are the best silver recovery results that I've ever seen when utilizing the
cyanidation process on Mexican silver deposits."


Orko provided 5 composites from drill core assay rejects to Westcoast Mineral
Testing Inc. of North Vancouver, BC, from which a single master composite,
grading a nominal 0.4 g/t Au and 300 g/t Ag was prepared.


Three cyanidation tests were then completed by Process Research Associates (PRA)
of Richmond, BC. The first test determined that cyanidation is an effective
processing option for this deposit. The next two tests evaluated cyanide
concentration and grind. The cyanidation testing reported the following:


- A medium fine grinding is required to adequately expose the precious metals
for cyanidation. The optimum has not yet been determined but it would appear to
be about P80 equals 100 microns, or 70% passing 200 mesh.


- The tests also indicate that the optimum cyanide concentration will be in the
range of 1 - 2 g/l. This is reflected by a cyanide consumption of about 2.3
kg/t.


- Under these conditions, 88% silver and 75% gold extractions can be expected.

- The data suggests that finer grinding will increase the silver recovery to
approximately 90%.


Flotation concentration reported only 73.5% silver and 44.0% gold recovery from
the master composite. The data from this single test indicated that flotation is
unlikely to be a desirable processing option, so future testing will investigate
only cyanidation.


This initial laboratory testing program has adequately defined the processing
parameters for the submitted samples, so that the exploration program can
proceed with the knowledge that the material can be processed in a conventional
agitation cyanidation circuit.


The initial laboratory testing shows an improvement of 5% in silver recovery
compared with historical data available from Luismin which indicated initial
recoveries of 85% silver and 75% gold. Elsewhere in Mexico, other silver
companies report recoveries of 50% - 90%, the La Preciosa results appear to be
comparable with some of the better metallurgical recoveries reported.


As the exploration program advances, additional bench scale testing will be
completed to determine the universality of these results and to evaluate other
processing characteristics to confirm that the silver recovery will achieve 90%
recovery or better.
