ECU Silver Mining Inc.: Press Release

TORREON, COAHUILA--(CCNMatthews - May 18, 2006) - ECU Silver Mining Inc. (TSX VENTURE:ECU) -

- Average grades for the stockwork zone in the 17.5 level cross-cut increased to 2.43 g/t Au, 57 g/t Ag, 0.23% Pb and 0.44% Zn Ag over 28.2 meters when including missing gold and silver assays for a 7.4 meters section and the missing lead and zinc assays;

- Confirmation of continuity of the stockwork zone by step-out drilling with hole TA 17.5-06 returning 31 meters (true thickness) grading 1.21 g/t Au and 36.8 g/t Ag.

ECU Silver Mining Inc. (the "Company") wishes to announce results from the previously missing 7.4 meters section of the stockwork zone as well as results from drill hole TA 17.5-06 which intercepted the stockwork zone 40 meters west and an average of 60 meters deeper than the cross-cut where it was first encountered (See Stockwatch press release 2006-05-08).

The Company is pleased to report that assays were received for the 7.42-metre section of the stockwork that was given a grade value of nil previously. The missing gold and silver assays from the stockwork intercept in the 17.5 cross-cut (See Stockwatch press release 2006-05-08) were received and increased the averages grades for the whole 28.2 meters section from 2.19 g/t Au and 55 g/t Ag to 2.43 g/t Au, 57 g/t Ag, 0.23% Pb and 0.44% Zn. Given the bulk tonnage potential of the zone, this increase in overall grades is significant.

Drill hole TA 17.5-06 was a step-out hole whose primary purpose was to provide data to confirm the continuity of the stockwork zone, both laterally and vertically. We are pleased to report that the zone to this point (see table 1-A below) encountered grades of 1.21 g/t Au and 36.8 g/t Ag over a core length of 41.58 meters (true thickness of 31 meters). As stated in our last press release, this new zone on level 17.5 is perfectly shaped for large-scale bulk mining and this latest data provided the base to calculate a first resources block (80 meters long, 120 meters high and 29.6 meters thick) containing approximately 800,000 tonnes or sufficient material to feed our current mill at 8,000 tonnes per month for more than 8 years. The drill will continue with further step-out holes as a priority of the current exploration program because the Company strongly believes that the area to be defined is much larger.

Furthermore, there is a 1.66 meter section of the A4 vein that is missing (immediately after the 2.32 meters of veins that was recovered see Table 1A below). The Company must point out that this missing data could be significant should the assays recovered demonstrate grades that are similar to what we have been obtaining from the "A4" vein. Case in point, the average grades for the "A4" on level 17.5 is 8.57 g/t Au, 302 g/t Ag, 2.16% Pb and 2.54% Zn. The Company plans to use wedging techniques in an attempt to recover this section before drilling the next hole in this zone.

"The Company is extremely pleased with the results from our second contact with this new stockwork zone on level 17.5, between the A4 vein and the Santa Juana vein, and in hole TA 17.5-06. Already, hole17.5-06 has provided excellent data with solid grades that clearly demonstrates the continuity of the stockwork zone, both vertical and laterally. While further work is still required in an effort to better define the entire section, the Company is of the opinion that this latest discovery will have a material positive impact on our Mineral Inventory once this data has been integrated in a NI (National (Instrument) 43-101-compliant technical report," noted Michel Roy, president and chief executive officer of ECU Silver Mining.

The Company anticipates that the next step-out hole will start early next week. Assays will be released as they become available.

All the samples represent the core length and may not be representative of the true width. Samples were assayed at ERSA, in Torreon, Coahuila, Mexico. Property specific quality control samples were inserted at regular intervals in the sample sequence.

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 a junior Gold, Silver, Zinc and Lead producer in the prolific mining district of Velardena, Mexico where historically over 500,000 ounces of Gold and 250,000,000 ounces of silver have been mined. Full scale production began in May 2005 at the Company's Santa Juana mine. To ensure the Company is positioned for continued growth and expansion, and to take full advantage of the current record setting metals prices, the Company has a fully operational infrastructure in place, several months of planned production available from the current stopes, and ongoing exploration programs.
