ECU Silver Confirms Massive Sulphide at Depth

ECU Silver Mining (TSX: ECU) ("ECU Silver" or "the Company") is very pleased to announce that it has confirmed grades from the two massive sulphide veins intercepted at depth. The first drill intercept yielded 3.66 g/t Au, 295 g/t Ag, 7.87% Pb and 12.07% Zn over a core length of 12.04 metres (40 feet) (17 g/t Au equivalent or 1,100 g/t Ag equivalent). The second intercept yielded 7.90 g/t Au, 550 g/t Ag, 11.25% Pb and 27.68% Zn over a core length of 1.75 metre (6 feet) (33 g/t Au equivalent or 2,180 g/t Ag equivalent).

The four key points regarding the two massive sulphide veins (the "M-S Veins") include:

- The M-S Veins were intercepted at double the depth of the current N.I.
  43-101 mineral resource estimate in this region.

- The grades in the M-S Veins are substantially higher than the Santa
  Juana N.I. 43-101 Inferred Resource grades.

- Drilling has entered a zone where a multiple number of massive
  sulphide lenses may be found.

- The extent of the alteration zone is unknown as drilling has not yet
  reached the intrusive.

These drill results (see Table 1) are considered to be extremely significant as they provide a high level of confidence to the geological model which suggests the potential for the discovery of additional deep seated massive sulphide replacement (Mantos-type) deposits. These Mantos-type sulphide deposits represent major sources of precious and base metals in a high-grade, high tonnage ratio.

The above mentioned key points concerning the M-S Veins are summarized as follows:

1. The M-S Veins were intercepted at double the depth of the current N.I. 43-101 mineral resource estimate in this region.

As reported previously (see press release dated July 2, 2008), drill hole SJ-18-21 intercepted the "M-S Veins" at a depth of 900 metres (2,950 feet) below level 18. This is double the depth limit, from level 18, of the current N.I. 43-101 resource estimate for this region, which encompasses the Santa Juana veins system. In the last N.I. 43-101 resource estimate, the Inferred Resources for that section of the Santa Juana veins complex were calculated from a depth of 150 metres (490 feet) to a maximum depth of 450 metres (1,480 feet) below level 18 representing a total height of approximately 300 metres (980 feet). Drill hole SJ-18-21 cut the M-S Veins 900 metres (2,950 feet) below level 18 or another 450 metres (1,480 feet) below the current mineral resource limit. As such, the M-S veins demonstrate the continuity of the mineralized system from the current mine levels all the way down to nearly one kilometre below level 18. We intend to integrate an inferred resource block that will now extend for a vertical distance of 800 metres (2,620 feet), versus the previous 300 metres (980 feet), into the next N.I. 43-101 resource update. The current N.I. 43-101 for Santa Juana alone, defines a Measured and Indicated resource of 31.5 million ounces of silver equivalent (versus a total for all Velardena Properties of 37.6 million ounces) and an Inferred Resource of 70.5 million ounces of silver equivalent (versus a total for all Velardena Properties of 179 million ounces).

2. The grades in the M-S Veins are substantially higher than the Santa Juana N.I. 43-101 Inferred Resource grades.

The grades of the intercepts for the M-S Veins are very high, especially in base metals, compared to the average grade for the Inferred Resource at Santa Juana as defined basically between level 18 and 450 metres (1,480 feet) below. A new Inferred Resource calculated between level 18 and 900 metres (2,950 feet) may positively impact the average grade of the updated Inferred Resource category.

3. Drilling has entered a zone where a multiple number of massive sulphide lenses may be found.

The M-S Veins are within the marble/skarn alteration zone. The marble/skarn unit is typically associated with a zone of alteration occurring at the contact between the intrusive body and the limestone host rock. The most favourable portion of the alteration zone is the contact between the intrusive and the marble/skarn where thick lenses of massive sulphides typically form.

4. The extent of the alteration zone is unknown as drilling has not yet reached the intrusive.

The Santa Juana veins system is bound by two prominent veins in the upper levels, the Santa Juana Vein to the north-east and the more prominent A4 Vein to the south-west. At the upper levels of the Santa Juana mine, the A4 vein is located at the contact between the skarn and the intrusive. Consequently, the first M-S Vein may represent the downward extension of the Santa Juana vein and thus represent the first major vein, at depth, of the package of veins that comprise the Santa Juana veins system. At depth, the drill reached its maximum drilling depth and stopped within the marble/skarn alteration zone before hitting the intrusive. As such, there is a reasonable expectation that another massive sulphide vein, corresponding to the depth extension of the A4 vein, will be located to the south-west at the intrusive contact.
