ECU Silver Uncovers Mantos-Type Mineralization at Chicago Mine

TORONTO, ONTARIO--(Marketwire - Dec. 6, 2010) - ECU Silver Mining Inc. (TSX:ECU) is pleased to announce that it has discovered a "mantos-type" mineralized zone (also known as a "Chimney") in the new underground development at the Chicago mine. The newly discovered zone included a cut assaying 350 grams per tonne (g/t) silver (Ag), 6.40% lead (Pb) and 12.13% Zn over a width of 3.0 meters (m) (10 feet).

Michel Roy, CEO and Chairman of ECU stated, "The mantos-type of mineralization is typically related to replacement bodies which is a very encouraging development for us, as some of the best orebodies in Mexico are of this type of mineralization. Historical mining in "mantos" style deposits have shown that these types of mineralization are generally associated with very high grades and good widths."

The new mineralization was discovered through an underground drift that was following the "Gambusinos" vein in the Chicago mine. The mantos is differentiated from the mineralized veins in that the mineralization consists of replacement bodies inserted between limestone beds. This type of mineralization, while normally limited in lateral extent, can be followed for significant distances along its plunge and is typically much wider than normal veins. The mantos deposits typically contains higher than normal grades of silver, lead and zinc. Assays to date are:

Sample # Width (m) Ag (g/t) Pb (%) Zn (%)
75792-793 2,90 395 5.18 7.64
75794 3,00 350 6.40 12.13
76953-954 2,70 104 1.06 1.26
76955-956-957 3,80 125 0.96 1.20
76958-959-960 4,30 42 1,35 3.27
76961-962 3,20 24 0.69 4.04
Average of 6 cuts 3.32 161 2.45 4.70

To date, six cuts have been assayed with an average grade of 161 g/t Ag, 2.45% Pb and 4.70% Zn over an average width of 3.3 m (11 feet). Much higher grades can commonly exist in mantos style deposits which would suggest that the newly discovered zone is near the top of the structure. Consequently it is expected that grades will improve as development goes further down plunge along the mantos.

Cautionary Statements

Readers are cautioned that until a prefeasibility study is completed, there are no assurances these latest mineralized zones 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. Mr. Michel Roy, P. Geo., a "qualified person" within the meaning of NI 43-101, prepared the technical information disclosed in this news release.
