  ECU Silver Continues Exploration Success in Northern Branch of
  Terneras East
=======================================================================

Highlights

- 19 cuts yields average of 2.15 g/t Au, 1257 g/t Ag, 5.06% Pb and
4.88% Zn over width of 0.4 metres representing a total length of 70
metres.

- Results are in a region identified as Potential in current NI 43-101.

TORONTO, ONTARIO, May 28, 2008 - ECU Silver Mining (TSX:ECU) ("ECU
Silver" or the "Company") is pleased to announce results at the main
Velarde�a Property. Recent assays from a cross-cut in the northern
branch of the eastern extension of the major Terneras vein ("Terneras
East - North Branch") resulted in 19 cuts, total length of 70 metres,
yielding an average of 2.15 g/t Au, 1257 g/t Ag, 5.06% Pb and 4.88% Zn
over an average width of 0.4 metres (see Table 1). Eliminating four
lower grade cuts and averaging cuts #1 to #15, total length of 45
metres, yielded an average of 1.64 g/t Au, 1,941 g/t Ag, 7.66% Pb and
7.20% Zn over 0.31 metres.

The eastern extension of the Terneras vein ("Terneras East") is one of
certain key areas where the Company has identified a Mineral Potential
of 465 to 807 million silver equivalent ounces as disclosed in the most
recent National Instrument 43-101 Technical Report which was audited by
Micon (the "Micon Report"). An east-west trending drift has so far,
been opened for 70 metres along the Terneras vein and is continuing
laterally in both directions. Terneras East is quite interesting as it
is completely open for another 400 metres laterally and for more than
600 metres at depth. Recent development work in the
area has been focused on the north branch of Terneras East where grades
and widths above cut-off are being systematically encountered. The
eastern side of the Terneras vein is proving grade and width continuity
which are the two key criteria in the requirements to convert from
Mineral Potential into an inferred mineral resource.

Assays received for the 70 metres of drift are well within the cut-off
grades with some assays yielding up to 8,444 g/t Ag. The assay results
are in an area where the Company had only Mineral Potential identified
in the Micon Report. The objective is to continue to focus our
exploration and development work in the areas identified as Mineral
Potential in the Micon Report.

The latest results continue to support the concept that Terneras East
is a system of veins where, eventually, several veins may be included
into a future updated N.I. 43-101 mineral resource estimate.

The drift at Terneras East will continue eastward and will be used as a
drill station to test the south branch of the Terneras East vein as
well as other significant targets in that area.

We are continuing exploration drifting at the Santa Juana vein system
in the northern part of the main Velarde�a Property. We also completed
a cross-cut on Level 18 adjacent to a stockwork of vein packages (the
"A's Package"). Several additional veins were found in this new area
and we are currently compiling results.

Cautionary Statements

The Mineral Potential quantity and grade of the Velarde�a Properties
are conceptual in nature and there has been insufficient exploration
conducted within the Mineral Potential evaluation to define a mineral
resource. It is also uncertain if further exploration will result in
the targets being delineated as mineral resources.

Readers are cautioned that there are no assurances that all or any part
of the Mineral Potential will be economically viable and although the
information in this press release is based on the best available data
the Company has collected to date, a material difference between the
actual results and the Company's expectations may arise once further
exploration is completed.
