ECU Silver's Current Workings Average 12.85 g/t Au and 468 g/t Ag over 0.44 metres from 106 samples at Santa Juana Mine
Wednesday July 19, 4:49 pm ET
TORREON, COAHUILA--(CCNMatthews - July 19, 2006) - ECU Silver Mining Inc. (TSX VENTURE:ECU - News) -
- Average sampling of current workings yielded 12.85 g/t Au and 468 g/t Ag over 0.44 meters for 106 samples coming from 12 workings places on four levels;
- "San Mateo" vein was followed for 39 meters in the intrusive and yielded an average of 3.58 g/t Au and 591 g/t Ag over 0.39 meter;
- Purchased own drill with plans to add another three drills shortly.
ECU Silver Mining Inc. (the "Company") (TSX VENTURE:ECU - News) is pleased to announce new assay results from underground development and mining in the Santa Juana mine from the A1, A2, A3, A4 and Santa Juana veins on levels 15, 15.5, 17 and 17.5.
Results from Santa Juana Mine:
These 106 samples, gathered from various active areas of the mine, represent a fair picture of the type of material the Company is currently mining, and the type of blend that is being sent to the mill. Table 1 below illustrates that the average grades of all the workings yielded 12.85 g/t Au and 468 g/t Ag over 0.44 m. It is also a very strong support for the accuracy of the new NI 43-101 compliant technical report which reported an average of 4.95 g/t Au and 208 g/t Ag over 1.1 meter (diluted) for the indicated sulfide resources in the Santa Juana mine which corresponded to the area we are currently working in.

Update on the San Mateo Vein:
In other areas of the project, drifting going west on the San Mateo vein was in a sulfide type vein within a dioritic host rock as opposed to the oxidized material encountered in the drift going east in the limestones which yielded 4.27 g/t Au and 93 g/t Ag over 1.16 meter in an 85 meters section of drift (see Stockwatch June 1, 2006). Typical of that area, the vein is thinner with a mixture of spectacular assays for silver. However, it is far more consistent on this level than what had been observed on levels 1 and 2 and the much higher average silver grade, compared to the oxidized section, shows that silver is the predominant economic mineral in the non-leached portion of that vein. The Company plans to test this structure at depth by drilling to verify if this trend continues.

Other developments:
The Company is pleased to announce it has purchased outright the drill and equipment being used by our contractor as of last Saturday to insure future drilling will continue unimpeded. Currently, the Company is operating with its own crews and work is progressing smoothly. Furthermore, the Company is in the process of purchasing another two underground drills plus one surface drill and hopes the transaction to be completed before the end of July.
The Company also wishes to report that our on-site laboratory is almost completed and should be fully operational by end of August. Once fully operational, this will be of great benefit to the company as:
1) Expenses from current assaying will be reduced significantly;
2) We will be able to process results in a matter of days instead of the current 4-8 weeks.
"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 grades speak for themselves. We are also most encouraged with the latest initial findings of hole TA 17.5 -09 in the stockwork section which is probing a new area and has already encountered heavy mineralization. The Company continues to gather further data that supports our decision to purchase additional drills, as we feel we are still just at the beginning of uncovering the orebody on our property. The completion of the on-site Lab shortly will be a great asset, especially given the quantity of samples that will be collected once we have three drills working at the same time." noted Michel Roy, president and chief executive officer of ECU Silver Mining.
At present time, hole TA 17.5 -09 in the stockwork section is probing a new area and has already encountered heavy mineralization in the first few meters. The Company intends to focus in this particular area and data from initial drilling have already been sent for assaying. Results will be reported as soon as they become available.
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.
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.
