OSR Oro Silver Resources Ltd.

Oro Silver Resources Ltd. ("Oro Silver or the "Company") (TSX VENTURE:OSR) has
completed clay, geophysical, structural geology, and satellite image surveys on
its El Compas property within the Fresnillo Trend near Zacatecas, Mexico (see
Map 1). These surveys suggest significant potential exists for discovery of
high-grade silver below the gold bearing zones at the mine site. These studies
have indicated some significant findings: 




--  A compilation of the 2009 survey results indicate high-grade silver may
    exist below the gold bearing zones at El Compas, El Orito, and the
    northwest trending Escuadra Fault (this theory is supported by a drill
    hole completed by Hochschild Mining in 2006 which intersected 703 g/t
    silver and 4.1 g/t gold over 0.9m at 425m below surface). 

--  Geological studies at El Compas show epithermal style mineralization
    similar to other veins systems in the Zacatecas region, including MAG
    Silver's Juanicipio Project (resource: 238 Million ounces silver). 

--  Clay studies indicate that mineralogy can be used at El Compas for
    target vectoring gold and silver veins.  



"The potential for significant high-grade silver veins exists below the El
Compas mine and all the studies seem to support our conceptual model. These
surveys have enabled us to plan a carefully designed drill program targeting
silver which will get underway this month. It's important to remember that prior
to the Mexican revolution, in the 1930's, most mines were located at shallow
depths and only recently has modern exploration been applied to these old mining
districts. We expect that more announcements like the Juanicipio Project
discovery will occur in the Zacatecas area," stated Darren Bahrey, President of
Oro Silver.


Summary of the surveys conducted 

In order to better understand the geology at El Compas the Company conducted
geological bedrock mapping (both on-surface and underground), clay mineralogy
surveys, satellite imagery, and geophysical studies over the areas of known
mineralization, and elsewhere on the property. The objective of these surveys
was to help guide upcoming drilling efforts to test silver targets located
beneath the near-surface gold targets. These surveys have been used successfully
elsewhere in the Zacatecas district. 


CLAY STUDIES 

Clays are a component of weathered bedrock, and also may be related to
hydrothermal alteration. There are many different types of clay, each having a
unique chemical composition. Clay studies can be used in mineral exploration to
vector towards mineralized zones since certain clays are found to be located
closer than others to precious metal bearing bodies. Clay studies suggest that
high-grade silver mineralization may be located at deeper levels below the El
Compas mine. 


Eighty-five reconnaissance clay samples were collected within 1.6 km of the El
Compas mine and then analyzed by infrared spectroscopy. The results of the
sampling indicate clay mineral zonation that is spatially related to known
mineralized structures. The zoned alteration assemblage is characterized by: (1)
proximal buddingtonite and arsenate/phosphate clay mineral; (2) intermediate
kaolinite; and (3) distal smectite. Buddingtonite is part of the advanced
argillic alteration assemblage and is strongly associated with the mineralized
hangingwall sections of the northwest-trending Escuadra Fault system and not
with the north-south trending mineralized structures. At the Fresnillo mine (the
world's largest silver mine), located approximately 45 kilometres to the
northwest, buddingtonite is associated with northwest structures on the flanks
of the deposit. 


In addition to clay sampling, regional scale detection and mapping of clay
alteration was carried out using ASTER satellite imagery by multispectral and
hyperspectral analysis. Both the multispectral and hyperspectral data identified
large areas of clay alteration, especially in the western portion of the El
Compas property. Hyperspectral data identified combinations of kaolinite,
smectite, illite, and dickite roughly coincident with results of the
multispectral analysis. The presence of a large clay alteration zone suggests
the upper part of a potentially large epithermal system (see map 2) has been
preserved and that the main precious and base metal mineralized zones could
exist at depth in the vicinity of the El Compas mine.


GEOPHYSICAL STUDIES 

Geophysical surveys were conducted to help understand the geology, structure and
possible orientations of the mineralized veins. Induced Polarization (IP) and
magnetometry (mag) geophysical orientation surveys were conducted over the El
Compas mine and other important target structures, to determine the
effectiveness of geophysics as a prospecting and subsurface mapping tool.
North-south oriented IP lines identified the northwest trending Escuadra Fault
as a strong southwest dipping resistivity low, to a depth of more than 300m.
East-west oriented mag lines delineated magnetic lows coincident with the main
trend of the El Compas ore body. IP appears to be an effective method for
identifying and mapping the Escuadra Fault and possibly other less obvious but
potentially important northwest structures. Magnetometry, demonstrated an
ability to map alteration zones associated with north-south trending vein
systems such as El Compas. These surveys will allow the Company to identify and
delineate prospective target structures below the El Compas mine and elsewhere
on the property.


STRUCTURAL GEOLOGICAL STUDIES 

The Zacatecas district hosts several, high-grade, silver deposits along the
Fresnillo Trend primarily within northwest trending structures. In nearby mines
sites such as El Bote, Cozamin, Veta Grande, and Fresnillo, tectonic uplift and
subsequent erosion over millions of years has removed the upper gold rich zone;
consequently these deposits are all characterized by low gold, high silver, and
high base metal content representing the deeper parts of an epithermal system
(see maps 2 and 3). More recent discoveries along the Fresnillo Trend include
MAG Silver's Juanicipio project. 


At both El Compas and Juanicipio, post-mineral erosion has not removed the
higher elevation (upper), gold-rich portion of the epithermal vein system (see
map 2). At El Compas, one hole completed in 2006, by another explorer,
intersected the northwest striking Escuadra Fault. A 0.9-metre wide quartz vein
sample within this fault (structure) returned 4.1 g/t gold and 703 g/t silver at
a vertical depth of 425 metres below surface. This is similar to the first
exploration holes drilled at Juanicipio in terms of width, grade, and depth.
Subsequent deeper drilling at Juanicipio discovered a silver-rich bonanza zone
about 150 metres below the first exploration holes. Similarities to MAG Silver's
Juanicipio property, and past-producing Cantera and El Bote mines (historical
production of 250-300 million ounces silver, 7 kilometres to the north) coupled
with survey results provide strong support for discovering high-grade silver and
gold mineralization at depth below the El Compas mine. Mr. Thomas Bagan, P. Eng

Oro Silver is a silver exploration company pursuing early and advanced stage
silver-based opportunities in Mexico. Oro Silver's mandate is to develop
properties toward silver production through a strategic business arrangement and
development plan focused on advanced-stage projects with known silver resources
that exhibit potential for expansion. The El Compas mine continues to be the
cornerstone for Oro Silver's growth strategy in the Zacatecas silver district.
The Zacatecas silver district is the world's largest silver district and is well
known for its silver production as the Fresnillo Mine 45km to the northeast,
held by Industrias Penoles, currently produces over 31 million ounces of silver
annually from high-grade (23 oz/T Ag plus up to 0.1 oz/T Au) veins. Fresnillo
commenced mining around 1560 and has produced about 800 million ounces of
silver.
