      ECU Silver Continues Exploration Success at Terneras East
=======================================================================

Highlights

..  2.0 metres (7 feet) grading 2.0 g/t Gold, 1,455 g/t Silver, 6.2%
   Lead and 2.5% Zinc.

..  1.6 metres (5 feet) grading 4.1 g/t Gold, 447 g/t Silver, 0.8% Lead
   and 2.1% Zinc.

Toronto, Ontario, August 12, 2008 - ECU Silver Mining (TSX:ECU) ("ECU
Silver" or "the Company") is pleased to announce further exploration
results from the Terneras Vein within the main Velarde�a Property. The
Company's exploration activities in this particular area of Velarde�a,
have continued to demonstrate extensive continuity on the eastern
extension of the main Terneras Vein ("Terneras East"). Terneras East
was first identified in our press release dated October 16, 2007 and
since that time, the Company has identified two high grade mineralized
vein branches extending east of the main Terneras Vein, namely, the
Northern Branch and the Southern Branch of Terneras East. Earlier
results demonstrated robust assay results for the Northern Branch (see
press releases dated March 31, and May 28, 2008) and more recently,
results from the Southern Branch of Terneras East have also
demonstrated very encouraging assay results based on drilling data and
drift sampling.

Drill results are from a surface drill which was located on a new
access road driven to test the eastern extension of Terneras East,
previously discovered by underground drifting. Drill hole, TE08-01 cut
the eastern extension of the Terneras Vein approximately 300 metres
below surface while drill hole TE08-03 cut Terneras East approximately
550 metres below surface. TE08-01 is approximately 150 metres east of
TE08-03. Note that a deep hole, TE08-02, extended to 700 metres and
could no longer extend further and as such did not reach the projected
Terneras East intersection, it will be continued at a later date.

Hole TE08-01 returned 2.05 metres (7 feet) grading 2.00 g/t Gold, 1,455
g/t Silver, 6.16% Lead and 2.50% Zinc (see Table 1) and hole TE08-03
returned 1.57 metres (5 feet) grading 4.10 g/t Gold, 447 g/t Silver,
0.76% Lead and 2.10% Zinc (see Table 2) after cutting three other veins
that have not yet been correlated to other drill intersections but
might be once more drill holes are completed in this area.

These results are notable in that Terneras East is showing evidence of
ongoing high grades and excellent lateral and depth continuity while
more veins of interest are being encountered in the same neighbourhood.

(i) Represents intersection of Terneras East - Southern Branch

Since early in the year, the Company has been working from the
north-south trending San Juanes adit to verify the continuity of the
main east-west trending Terneras Vein from the east side of the Tres
Aguilas fault. The Northern Branch and Southern Branch of the Terneras
East vein system were sampled by driving east and west development
drifts from the San Juanes adit and oriented along the strike of these
vein branches. In addition, bazooka drill holes were completed from one
development drift to the other, in order to transect other veins in the
area which run essentially parallel and between the Northern and
Southern vein branches. Sample results from the bazooka drilling are
summarized in Table 3.

(i) Represents intersection of Terneras East - Southern Branch

These results are encouraging as they provide ongoing evidence of the
extensive mineralization near the eastern continuity of the Terneras
Vein, including excellent assays within the vein itself as demonstrated
by sample 51382 which is interpreted as being a cut of the Southern
Branch of Terneras East.

In addition to these results, the development drift running along the
Southern Branch of Terneras East encountered an old production raise
leading upwards to the Pjiorina Vein, located approximately 80 metres
above the Southern Branch development drift. This Pjiorina Vein has
actually been interpreted to be the ongoing lateral continuation of the
Southern Branch of Terneras East. The Pjiorina Vein was sampled in the
late 1990's with results shown in Table 4. That sampling showed a
progression from a thin precious metal bearing vein to a much wider
base metal rich vein (unfortunately the samples were not assayed for
lead in those days). This phenomenon was encountered in several areas
of the property, leading to the belief that the Terneras Vein system
may demonstrate much richer base metal values along with the precious
metals as we trend eastwardly.

As previously reported, the Terneras Vein was the largest historical
producer in the Velarde�a area with more than 1,000 miners working on
the site until 1968. The main feature of the Terneras Vein is its
impressive continuity which has been mined laterally for 1,200 metres
and vertically for 600 metres. The lateral limits of the vein were
related to faults that displaced the vein in an unknown direction and
many efforts, since the early 1900's, to find the extensions were
unsuccessful, until recently through the Company's successful
exploration efforts.

Cautionary Statements and Additional Information:

Readers are cautioned that until a prefeasibility study is completed,
there are no assurances these latest mineralized zones will be
economically viable.

All true widths from holes TE 08-01 and TE 08-03 correspond to
approximately 50 to 65% of the core lengths mentioned, all other widths
are true widths. Samples were assayed at the ERSA laboratory in
Torre�n, Coahuila, Mexico which is currently in the process of being
certified. Mr. Michel Roy, P. Geo., a "qualified person" within the
meaning of NI 43-101, prepared the technical information disclosed in
this news release.

ECU Silver Mining Inc. is focused on the exploration, development and
mining of gold, silver and base metals at its Velarde�a District
Properties in Durango, Mexico. The area is comprised of three
properties, the Main Velarde�a Property, the Chicago Property and the
San Diego Property. The properties are located near to each other and
include five historical mines - Santa Juana, Terneras, San Mateo, San
Juanes, and the San Diego mine. ECU's goal is to establish a
significant polymetallic mineral resource in the heart of Mexico. ECU's
mission is to become a pre-eminent silver and gold producer through the
development of existing, and additional potential resources at
Velarde�a.
