ECU Silver Mining, Inc.: Operating Results

TORREON, COAHUILA--(CCNMatthews - June 23, 2005) - ECU Silver Mining

ECU Silver Mining Inc. (the Company) is pleased to report sales of approximately US$293,500 in May from operations at the Velardena property. Despite the fact that the mill was down for nearly a week for upgrading the crushing circuit, ECU managed to successfully process 4,629 tonnes in May. Consequently, during this period, the mill worked for only 19 days with in a production of 174.6 tonnes of lead concentrate (concentration ratio of 26.5:1) and 227 tonnes of zinc concentrate (concentration ratio of 20.4:1).

The average grades for that period were:

Au g/t Ag g/t Pb % Zn %
Feed 7.2 267 2.17 4.22
Pb Concentrate 6.29 4,980 41.8
Zn Concentrate 501 53.4
Tailings 6.82 26 0.50 1.12

Considering the concentrates produced and the above assays, the recoveries of payable metals were approximately 85% of the silver, 73% of the lead and 64% of the zinc. Those reflect a mixture of better results at the end of the month after we modified the flotation circuits.

In June we processed 3,900 tonnes in 16 days to June 20 to produce 156 tonnes of lead concentrate and 206 tonnes of zinc concentrates having an approximate sale value of US$235,000. We should process an additional 1,500 tonnes at least in this month with slightly better concentration ratios than May.

All samples used to calculate the above averages were assayed at Ersa Global, Ensayes y Representaciones S.A. de C.V. in Torreon, Coahuila state, Mexico. Concentrate samples were taken from the operation as well as from each shipment with portions kept for reference and referee assaying should it be needed.

This work was carried out under the supervision of Mr. Michel Roy, P. Geo., a "qualified person" within the meaning of NI 43-101, who also prepared the technical information for disclosure in this news release.
