ECUXF - ECU Silver Mining Inc.: Length of Major Discovery on Level 15 Extented by 20 Meters
Wednesday September 6, 5:52 pm ET


NEW CROSS-CUT BEING DRIVEN ON LEVEL 18

CURRENT DRILLING HAS JUST REACHED OUR MAJOR MINERALIZED GREEN SKARN

New extension of San Mateo vein grades 8.16 g/t Gold and 449 g/t Silver;

Santa Juana workings grades 17.31 g/t Gold and 426 g/t Silver.


TORREON, COAHUILA--(MARKET WIRE)--Sep 6, 2006 -- ECU Silver Mining inc. (TSX VENTURE:ECU.V - News) -



ECU Silver Mining Inc. (the "Company") is pleased to announce new assay results from underground development and mining in the Tres Aguilas sector of the Santa Juana mine from the A1, A2 and A4 veins on levels 17 and 17.5 as well as from the San Mateo mine.

San Mateo Vein:

Following the development on level 6 of the San Mateo Mine (approximately 150 meters below surface) in the western portion of the San Mateo vein from which excellent assays were received (see the Company's press release August 8, 2006), further development in drifts and raises yielded more solid results (see Table 1 below).

In the raise, what is worthy of highlighting is that the grades and width over a length of 9 meters (29.5 feet) are increasing as we go up, as demonstrated by the changes from sample 38404 to 38406 below in Table 1.

In the drift, what is most important besides the grades is that this is an entirely new sector of the mine. Starting with sample 38658, we can observe an increase in width and a very significant increase in metals contents, including copper. The new findings and grades justify accelerating the development of this sector of the San Mateo mine as the Company is of the opinion that resources may exist West of our current program.

Vein Sample # Width m Au g/t Ag g/t Pb% Zn% Cu%
Raise San Mateo 38404 0.20 3.78 117 0.13 0.35

Average (6 samples) 0.37 8.16 449 0.84 2.52
Santa Juana Mine:

The samples in Table 2 below illustrate new information when compared to previously released data (see the Company's press release August 8, 2006). The samples from the A1 vein on levels 15.5 and 17 and from veins A2 and A4 veins on level 17.5 show good continuity both in grades and thickness when compared to previous results, and therefore confirming the trend of increasing metals contents as we go deeper.

"The Company believes these latest set of results from our vein systems confirm the need to continue our extensive development plan. The San Mateo vein continues to yield positive surprises and we are planning to open the vein at least an extra 100 meters going west until we reach the projection of a regional fault. Then a drilling program will be initiated to localize the vein on the other side of the fault before resuming the drifting." noted Michel Roy, president and chief executive officer of ECU Silver Mining.

Major Discovery on Level 15:

The on going development program on the newly discovered 6 meters wide zone on level 15 is continuing. The zone has been extended an extra 20 meters for a total of 60 meters in length and more secondary veins have been found. Assays are pending.

New Cross-Cut on Level 18:

On level 18, a major cross-cut is currently being driven to cut all the system of veins in that area.To this point, the cross-cut has intercepted several veins, some with very high values (see the Company's press release August 8, 2006), and the Company is awaiting the results of the latest findings. Assays are pending.

Current Drilling Program has reached Skarn#1:

The drilling program is on-going with the main target of the current hole being the green mineralized skarn (skarn #1).This work is being carried out from level 17.5 and the hole is being drilled on a -45 degree angle. The green skarn was expected to be reached approximately 100 meters below level 17.5.

What is worthy of noting at this time are the following:

1) At the beginning of this hole (from 0 to about 40 meters below level 17.5), the Company encountered several mineralized veins on the path leading to the target. These veins were cut and sampled. Assays are pending;

2) The company is pleased to announce that the hole has successfully reached the beginning of the mineralized green skarn. The core from this intercept will be sampled and assayed as soon as possible.

All widths are true widths. Samples were assayed at ERSA, in Torreon, Coahuila, Mexico, this laboratory is currently in the process of being certified, and at SGS in Durango, Durango, which is a certified laboratory. Property specific quality control samples were inserted at regular intervals in the sample sequence and the Company routinely does check assays at other certified laboratories.

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.
