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--(Marketwire - Aug. 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 Velardena Property. The Company's exploration activities in this particular area of Velardena, 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.

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.

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 Velardena 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 Torreon, 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 Velardena District Properties in Durango, Mexico. The area is comprised of three properties, the Main Velardena 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 Velardena.
