ECU Silver Announces New Assay Results on CC Vein at Santa Juana

Highlights - Assays averaged 27 g/t Gold, 544 g/t Silver, 2.7% Lead, 3.7% Zinc and 1.2% Copper over 0.44 metres. - Includes assays of up to 126 g/t gold and 2713 g/t silver.

TORONTO, ONTARIO--(Marketwire - Oct. 26, 2007) - ECU Silver Mining Inc. (TSX:ECU) ("ECU Silver" or the "Company") is pleased to announce that it has received new assay results from the Santa Juana area in the Velardena Property.

As part of the work related in completing our new mineral resource estimation, new drifts were driven whereupon the most important zones within the new drifts were drilled and/or sampled to fit within the new norms. One such zone, centered on a main vein in Santa Juana, the CC vein, on level 18 west of the Tres Aguilas fault. This zone was sampled for over 200 metres and assayed for precious and base metals. The results are listed in the Table 1 below.

These very high gold and silver assays, coupled with significant base metal values, represent the main CC vein which is enclosed in a wider mineralized zone that includes numerous smaller veins and veinlets. This mineralized zone forms the northern edge of one of the mineralized vein packages that are being defined within the Santa Juana Mineralized Corridor in the Velardena Property. ECU continues the assessment and interpretation of several mineralized vein packages within the Mineralized Corridor.

Also, as part of ECU's medium and long term exploration program, a new ramp is being driven which will accomplish two main objectives. First it will give us access to the vein system which extends below the current mine development at the Velardena Property. Second, it will provide a platform from which all the main veins at the Velardena Property can be drilled at depth and at much lower levels than currently reached. The planned length of the ramp is 2,500 metres of which the first 74 metres have been driven after the portal was completed.

43-101 Technical Report Update

We continue to advance our progress on the delivery of a new 43-101 mineral resource estimate which is scheduled for release this fall.

Last week, at our operations office in Torreon Mexico, a representative from our consultants, Micon International Limited ("Micon"), reviewed our work to date. We are pleased to report that our approach and methodology in determining our new mineral resource estimate were considered to be well within Micon's guidelines.

We are nearing completion of a 3-dimensional computer generated geologic model and the corresponding interpretation. The resulting new geologic 3-D model is anticipated to generate a comprehensive mineral resource estimate that will include results from the Mineralized Corridor at Santa Juana and from additional series of high grade veins located within the Velardena Property. In addition, results from the nearby Chicago and San Diego properties will also be included.

The new mineral resource estimate will be predominantly a precious metal resource comprised mainly of silver and gold values. This new resource estimate will be augmented with additional base metal values of zinc, lead and copper.

The Company is very excited about the upcoming resource estimate as we believe it will rank highly among all other world class silver assets.

Readers are cautioned that until a complete pre-feasibility study is completed, there are no assurances that the mineralized zone discussed above will be economically viable.

All widths are true widths. Samples were assayed at the ERSA laboratory in Torreon, Coahuila, Mexico which is currently in the process of being certified. Samples were also assayed at the SGS laboratory in Durango, Durango State, 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.

Mr. Michel Roy, P. Geo., a "qualified person" within the meaning of NI 43-101, prepared the technical information disclosed in this news release.
