TORONTO, ONTARIO--(Marketwire - June 20, 2011) - ECU Silver Mining Inc. (News - Market indicators) is pleased to report the results from developing a new vein on the Nazas property which included assays grading up to 6.18 grams per tonne (g/t) gold (Au) and 2,755 g/t silver (Ag).

The Nazas property is under option to ECU Silver with the possibility of ECU Silver acquiring a 100% interest for payments totalling US$1,100,000 over the next two years.

While conducting bulk testing for mineralized material amenable to open pit mining, a two meter wide vein was uncovered and bulk tested separately. The structure associated with this vein has been followed along strike for over 500 meters. In the first bench, a height of nine meters of the bench was tested over 30 lateral meters with the average bulk grade of the two meter vein being 0.35 g/t Au and 68 g/t Ag over 19 samples, with the best assays being 0.84 g/t Au and 598 g/t Ag. In the second bench, three meters has been done to date, also over 30 lateral meters and assays averaged 0.72 g/t Au and 241 g/t Ag from 33 samples, with the best assay being 6.18 g/t Au and 2,755 g/t Ag.

Considering these preliminary results, the Company intends to continue opening the vein at depth and laterally as well as test other similar structures on the property.

Progress on drilling the deep seated massive sulphides has not progressed as quickly as originally planned due to mechanical problems with the drilling. These problems have been addressed and drilling has resumed.

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