ECU SILVER CONTINUES EXPLORATION SUCCESS IN NORTHERN BRANCH OF TERNERAS EAST

ECU Silver Mining has provided results at the main Velardena property. Recent assays from a cross-cut in the northern branch of the eastern extension of the major Terneras vein (Terneras East -- North branch) resulted in 19 cuts, total length of 70 metres, yielding an average of 2.15 g/t Au, 1257 g/t Ag, 5.06% Pb and 4.88% Zn over an average width of 0.4 metres (see Table 1). Eliminating four lower grade cuts and averaging cuts #1 to #15, total length of 45 metres, yielded an average of 1.64 g/t gold, 1,941 g/t silver, 7.66 per cent lead and 7.20 per cent zinc over 0.31 m.

Highlights:

• 19 cuts yielded averages of 2.15 grams per tonne gold, 1,257 g/t silver, 5.06 per cent lead and 4.88 per cent zinc over a width of 0.4 metre representing a total length of 70 metres.
• Results are in a region identified as potential in current NI 43-101.

The eastern extension of the Terneras vein (Terneras East) is one of certain key areas where the company has identified a Mineral Potential of 465 to 807 million silver equivalent ounces as disclosed in the most recent National Instrument 43-101 Technical Report which was audited by Micon. An east-west trending drift has so far, been opened for 70 metres along the Terneras vein and is continuing laterally in both directions. Terneras East is quite interesting as it is completely open for another 400 metres laterally and for more than 600 metres at depth. Recent development work in the area has been focused on the north branch of Terneras East where grades and widths above cut-off are being systematically encountered. The eastern side of the Terneras vein is proving grade and width continuity which are the two key criteria in the requirements to convert from Mineral Potential into an inferred mineral resource.

Assays received for the 70 metres of drift are well within the cut-off grades with some assays yielding up to 8,444 g/t Ag. The assay results are in an area where the Company had only Mineral Potential identified in the Micon Report. The objective is to continue to focus our exploration and development work in the areas identified as Mineral Potential in the Micon Report.

The latest results continue to support the concept that Terneras East is a system of veins where, eventually, several veins may be included into a future updated N.I. 43-101 mineral resource estimate.

The drift at Terneras East will continue eastward and will be used as a drill station to test the south branch of the Terneras East vein as well as other significant targets in that area.

We are continuing exploration drifting at the Santa Juana vein system in the northern part of the main Velardena Property. We also completed a cross-cut on Level 18 adjacent to a stockwork of vein packages (the "A's Package"). Several additional veins were found in this new area and we are currently compiling results.

Cautionary Statements

The Mineral Potential quantity and grade of the Velardena Properties are conceptual in nature and there has been insufficient exploration conducted within the Mineral Potential evaluation to define a mineral resource. It is also uncertain if further exploration will result in the targets being delineated as mineral resources.

Readers are cautioned that there are no assurances that all or any part of the Mineral Potential will be economically viable and although the information in this press release is based on the best available data the Company has collected to date, a material difference between the actual results and the Company's expectations may arise once further exploration is completed.
