ECU Silver Mining Inc.: Press Release

TORREON, COAHUILA--(CCNMatthews - May 25, 2006) - ECU Silver Mining inc. (TSX VENTURE:ECU) -

- "A4" vein development on level 17.5: 93 meters (305 ft) of drift averaged 8.89 g/t Au, 309 g/t Ag, 2.46% Pb and 2.98% Zn over an average width of 1.13 meter (3.7 ft);

- "A1" vein on level 15.5: averaged 12.21 g/t Au, 866 g/t Ag, 12.13% Pb and 20.89% Zn over a 0.76 meter (2.5 ft) width;

- "A2" and "A3" veins on level 17: average of 11.90 g/t Au and 659 g/t Ag over 0.38 meter (1.2 ft) and 14.45 g/t Au and 813 g/t Ag over 0.25 meter (0.8 ft);

- "San Mateo" vein entered the limestones with increasing widths up to 4 meters (13 ft) assays are pending.

ECU Silver Mining Inc. (the "Company") is pleased to announce further assay results from mining the A1 vein on the 15.5 level, the A2 vein and the A3 vein on level 17, the A4 vein on level 16 and 17.5, and drifting the Veta Oriente vein on level 12 The first four veins (A1-A4) are located in the Tres Aguilas area of the mine and the Veta Oriente vein is in the old section of the Santa Juana mine. These results were compiled from sampling the veins in new stopes, raises and drifts over several levels.

The results outlined in table 1A below were obtained from the "A4" vein, a stope on level 16, 21 meters of raise starting from level 17.5 and 93 meters of drift also on level 17.5. These results demonstrate two clear patterns. Firstly, the increase in the average width from 0.32 meter above level 16 to 1.13 meters on level 17.5. Secondly, a huge increase in base metals contents, from modest values on level 16 to an average of 2.46% Pb and 2.98% Zn on level 17.5. These results are extremely promising as data has already confirmed that the A4 vein extends at least 430 meters deeper below level 17.5 (see Stockwatch April 12, 2006) and our data continually provides us with more evidence that both grades and width keep improving at depth.

The data in Table 1B below are from mining the A1 vein on level 15.5 in a sulfide-rich section of the vein. The important fact to point out is the extremely high base metals contents of the vein while still maintaining equally high grades for both gold and silver. These assays demonstrate the high quality grades we can expect to encounter for both, precious and base metals, from other veins as we pass from their calcite-rich sections to their sulfide-rich sections.

Tables 1C and 1D below display the assays from the A2 and A3 veins from stopes on level 17. Both veins are currently in calcite-rich sections and thus we have the extremely high gold and silver grades. We expect these two veins to change to sulfide-rich type veins at depth where the base metals contents should be higher as shown by the A1 vein results above. Another point worth highlighting is that although the A2 and A3 are two entirely independent veins, they both have similar characteristics at the same elevation which is an excellent indication that they both should change to a sulfide-rich section together at depth.

Table 1E below contains the new and old (see Stockwatch April 12, 2006) results to date of drifting along a sulfide vein on level 12, near the main access to the Santa Juana mine internal winze. It is located in the old area of the Santa Juana mine and had been neglected because it was very thin in the main cross-cut. However, this new drifting revealed a very continuous and constant vein with excellent precious metals grades as well as solid lead and zinc grades, with lower copper.

"The Company is pleased with the continued excellent results we are obtaining from the stopes and drifts of our vein structures on various levels. The gold and silver grades are solid throughout and the base metals grades are significant in several sectors, as shown by the A1 vein assays which reached 12.13% lead and 20.69% zinc. Furthermore, the results of the A4 vein continue to show great potential as both grades and width continue to improve at depth. Given that the Company has already proven that the A4 vein extends over 430 meters deeper then where this data was collected from on level 17.5, should this pattern of higher grades and greater width at depth continue, the Company feels the A4 vein alone could provide mill feed for years to come." noted Michel Roy, president and chief executive officer of ECU Silver Mining.

In other areas of the project, drifting on the San Mateo vein has made excellent progress as we have reached the sector where the vein enters the limestones. The Company is pleased to announce that the section of the San Mateo vein we just encountered has widths up to four meters, while assays are pending.

All widths are true widths. Samples were assayed at ERSA, in Torreon, Coahuila, and at SGS new facility in Durango, Durango, Mexico. Property specific quality control samples were inserted at regular intervals in the sample sequence.

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.
