Mr. Michel Roy reports
ECU Silver Mining Inc. has provided further assay results from drifting the A4 vein on level 17.5, the A3 vein on level 17 and the new Veta Oriente vein on level 12: the first two are located in the Tres Aguilas area and the new Veta Oriente vein is in the old section of the Santa Juana mine. These results were compiled from sampling the veins in new drifts being driven to open new sections of these veins.
The results outlined in table 1A below were obtained from a drift opening the A4 vein on level 17.5 about 20 metres below previously opened areas. The grades continue to be consistent for this vein but the average width is better when compared with other levels. These results were instrumental in pinpointing the dip of the vein as well as interpreting that a five metres of core length of moderately mineralized vein found in hole TA 17.5-05A is the downward projection of the same A4 vein, 430 metres deeper (assays are pending). This more than tripled the known vertical extension of the A4 vein which is fast becoming a very important part of the company's resources base.

The data in Table 1B below represent the opened 70 metres length of drift along the A3 vein on level 17. The results demonstrated further evidence of solid precious metals grades, 9.70 g/t Au and 403 g/t Ag. One point that is now clear and worthy of noting is that the copper averages on this level are better than either the lead or the zinc grades. It is a confirmation of the trend that precious metals and copper grades are increasing in that whole sector, while the zinc and lead are higher on the fringes of it.

Table 1C below contains the results to date of drifting along a sulphide vein on level 12, near the main access to the Santa Juana mine internal winze. It is located in the old area of the Santa Juana mine and had been neglected because it was very thin in the main crosscut. However, this new drifting revealed a very continuous and constant vein with excellent precious metals grades as well as solid lead and zinc grades, with lower copper. This again shows the zoning from lead to zinc to copper as the company goes deeper and closer to the centre of the veins.

Furthermore, hole TA 17.5-05A intercepted the sphalerite-bearing green skarn (see Stockwatch on April 3, 2006) immediately after crossing a vein, now interpreted as the A4 vein, 430 metres below level 17.5. To this point the hole has cut 69 metres of the green skarn and drilling will continue in the same geological unit as data suggest the skarn might continue for a much greater distance. Sampling from this hole is under way and assays are pending.
Samples were assayed at ERSA, in Torreon, Coahuila, and at SGS's new facility in Durango, Mexico. Property specific quality control samples were inserted at regular intervals in the sample sequence.
