ECU SILVER ENTERS HIGH GRADE WORKINGS OF TERNERAS MINE

TORONTO, ONTARIO – June 7, 2011 -- ECU Silver Mining Inc. (TSX:ECU) is pleased to report that the Company has sampled up to 14.03 grams per tonne (g/t) gold (Au), 155 g/t silver (Ag), 1.21% lead (Pb) and 4.26% zinc (Zn) over 1.50 meters (5 feet) in the Terneras Mine . Historical workings in Terneras have demonstrated significant continuity reaching up to 1200 meters (3,940 feet).
The underground development ramp at the San Juanes mine reached old workings of the Terneras mine giving the Company access to developed levels which can be mined in the short term. The level that was reached was sampled on both side of a major fault that cuts the main Terneras vein.
On the west side of the fault, in the main body of the old mine known to extend for 1,200 meters, the vein is generally thicker with consistent high assays. The drift in this area was sampled for a length of 48 meters (157 feet) and yielded 3.25 g/t Au, 311 g/t Ag, 1.78% Pb and 2.05% Zn over a width of 0.65 meters (2 feet). The best section sampled was 14.03 g/t Au, 155 g/t Ag, 1.21% Pb and 4.26% Zn over 1.50 meters (5 feet). On the east side of the fault, the vein is thinner and assays are irregular. The average over 48 meters (157 feet) of drift is 2.82 g/t Au, 263 g/t Ag, 1.48% Pb and 1.75% Zn over 0.21 meters (0.7 feet).
A significant portion of the Terneras vein could be opened rapidly by rehabilitating the existing infrastructure. The portion of the Terneras vein developed by previous owners and mined until 1920, contained approximately 4,000,000 tonnes (over 60,000,000 ounces of silver) of mineralized material.
In an update of the deep drilling to test the deep seated massive sulphides, the new cut steepened the drill hole which would have caused the drill to cut the extension of the zone more than150 meters deeper than the original cut. Since the objective of the initial holes is to confirm vertical and horizontal continuity close to the vein, this was deemed too deep for an initial cut. Consequently, it was decided to use the navi-drill to flatten the hole and cut the zone at a higher elevation, but still significantly deeper than the initial intercept. The drilling is currently at a depth of 870 meters (2,850 feet), 55 meters (180 feet) below the original intercepts in hole SJ-18-21 and is now being deviated into the massive sulphide zone.
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.
