OSR Oro Silver Resources Ltd.

Oro Silver Resources Ltd. ("Oro Silver" or the "Company") (TSX VENTURE:OSR) has
commenced drilling on its El Compas project near Zacatecas, Mexico. The ongoing
5,000 metre drill program will focus on testing the potential down dip extension
of high-grade silver mineralization at the El Compas mine below hole 09COM054
(990.9 g/t silver and 4.70 g/t gold over 1.0 metre, see press release dated
February 15, 2010), and will also test northwest trending faults for high-grade
silver potential at depth.


Darren Bahrey, President of Oro Silver stated: "Most of our recent drilling has
focused on expanding the near surface gold-rich resource at the El Compas and El
Orito veins. Hole 09COM54 has demonstrated that a transition from near surface
high-grade gold to deeper high-grade silver-rich mineralization occurs below the
El Compas mine. The high-grade silver vein intercepted in hole 54 in addition to
another vein intercept drilled by a previous explorer to the east provide
rationale for drill testing the intersection of northwest and north-south
structural trends at depth for high-grade silver mineralization. The only way to
test this idea is with drilling."


Drilling by Oro Silver has been mostly focused on the near-surface, gold-rich
potential of the El Compas and other parallel trending vein systems. Now that
high-grade silver mineralization has been confirmed at depth within north-south
and NW trending structures, the Company is expanding its exploration focus to
include the idea that larger, silver-rich targets associated with the deeper
parts of the epithermal vein system could be present, in particular where these
mineralized structures intersect. The results of recent surface clay alteration
studies show mineral zonation centered around these intersecting structures that
includes proximal buddingtonite and arsenate/phosphate-bearing clays, and distal
kaolinite and smectite clays. It is the Company's belief that the intersecting
structures could represent blind target zones with increased potential for
high-grade silver mineralization at depth. A total of 2,500 metres of drilling
has been contemplated for deep targeting for silver-rich vein mineralization.
Initial targets include testing the down dip extension of the silver
mineralization intersected in hole 09COM054 below the El Compas mine, the
deepest significantly mineralized zone drilled to date below the mine, followed
by deep drill testing of the northwest trending Escuadra fault where it is
intersected by the north-south trending El Compas and EC-2 vein systems. The
potential surface manifestations of the intersecting structures above the target
zones may be only weakly developed due to the presence of a 200 to 250 metres
thick rhyolitic volcanic unit that overlies the more productive andesitic
volcanic rocks at depth in the area. Target depths for these latter holes are
calculated to be at least 600 metres below surface, and correspond to depths
that are comparable to bonanza grade mineralization at MAG Silver's Juanicipio
property. Additional drill targets are likely, as additional information from
ongoing surface exploration work becomes available.


Presently the Company is pre-collaring holes with an RC rig and plans to
complete the holes with a diamond-drill tail. This technique is cost saving and
allows for faster drilling and subsequent assay turn-around times.


2010 first quarter exploration plans

- A 2,500 metre drill program.

- Additional targeting surveys (geophysics, structural studies, and clay analysis).

- Completion of El Compas and El Orito geological model.

- Scoping studies and resource estimation work.

About Oro Silver

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 Fresnillo silver trend (known to have produced several billion
ounces of silver) is well known for its silver production as the Fresnillo Mine
45km to the northwest held by Industrias Penoles currently produce 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 the year 1560 and has produced
about 800 million ounces of silver (see http://www.penoles.com.mx).
