TORONTO, ONTARIO, Thursday March 6th, 2008 - ECU Silver Mining
(TSX:ECU) ("ECU Silver" or the "Company") is pleased to announce the
latest assay results from a cross-cut extending from the San Juanes
adit to the Terneras vein in which the extension of the Terneras vein
was confirmed on the east side of the Tres Aguilas fault.

In early January of 2008, the Company decided to continue the San
Juanes adit and began working on a cross-cut aimed at verifying the
continuity of the main east-west trending Terneras vein on the east
side of the Tres Aguilas fault which intersects the Terneras vein. This
work was based on interpretations from the 3-D geological model of the
recent NI 43-101 mineral resource estimate announced on January 24,
2008. The Company is pleased to report the following results from this
most recent work at the San Juanes adit.

The Terneras vein was cut 200 metres below surface and has been
followed, so far, along strike for 12 metres on the east side of the
Tres Aguilas fault. The cut was sampled every three metres with the
results shown below in Table 1. The table shows assay results for the
three series of chip samples, the average of these chip samples and the
average grade diluted over a one metre thickness, using nil values for
the diluted host rock. The chip samples averaged 0.17 metres grading
7.11 g/t gold, 1,865 g/t silver, 13.01% lead and 9.04% zinc. Also shown
in the table is a metallurgical sample for the entire 12 metre cut
taken over a one metre total width which yielded 3.4 g/t Au, 1,095 g/t
Ag, 5.66% Pb and 6.06% Zn.

This confirmation of the strike and dip of the Terneras vein is
consistent with the drill intercept reported October, 16th 2007, where
0.30 metres grading 2.70 g/t gold, 2,097 g/t silver, 0.55 % copper,
17.95% lead and 11.57% zinc was reported in hole SJ 14-02 approximately
256 metres below this recent cross-cut. As such, this cross-cut
provides additional confirmation that we have found the eastern
extension of the main Terneras vein. The cross-cut and previously
reported drill intercept identify an initial 450 metres (1,476 feet) of
vertical extension for the 12 metre lateral portion of the Terneras
vein.

---------------------------------------------------------------------------

The calculated assays from the metallurgical test sample clearly
demonstrate that the host rock carries significant values in precious
and base metals. The metallurgical test sample graded much higher than
the diluted average over the same width which used nil in the host
rock. The metallurgical sample also gave recoveries of 90.4% for Pb and
86.2% for Ag in the lead concentrate with a further 8.2% of Ag and 82%
of Zn in the zinc concentrate, with both concentrates being of very
high marketable quality.

This can only be explained by a phenomenon known as mineralized
stratigraphical
planes and are observed in the drift. Essentially, the mineralization
extends along the sedimentary planes on each side of the Terneras vein,
whereupon, small veinlets are extending for several centimetres on each
side of the Terneras vein providing for good average grades to the
whole metre section when including dilution.

Readers are cautioned that until a prefeasibility study is completed,
there are no assurances this latest mineralized zone will be
economically viable.

A further point of high interest is that the main cross-cut driven to
test the eastern extension of the Terneras vein transected what was
supposed to be a "barren" section. This section of the cross-cut was in
fact not barren and the Company was surprised and pleased to have
obtained the following results, shown in Table 2 below.

---------------------------------------------------------------------------

---------------------------------------------------------------------------
47526 0.15 1.00 1,016 0.24 2.52 3.20
---------------------------------------------------------------------------

In that portion of the cross-cut, thought to be barren, several
veinlets were cut that justify more investigation based on the grades
shown above in Table 2 (for precious and base metals). The expectation
both along strike and vertically is either to define a possible wide
low grade stockwork type zone or to find "chimneys" along the same
veins.

Readers are cautioned that these veinlets may not extend much further
than what is currently visible in our working.

Michel Roy, Chairman and Chief Executive Officer, said that: "As stated
in October of 2007, the Company believed that a brand new area of
exploration was now available in the eastern sector of the Terneras
vein which had never been tested before. We are pleased to have
confirmed the extension of the Terneras vein on the east side of the
Tres Aguilas fault and the system continues to show tremendous
continuity and robust grades which is typical of these extensive-type
veins."

Our exploration work will continue on the area surrounding the eastern
extension of the Terneras vein. The work will include a continuation of
the cross-cut further to the north in search of new veins. We will also
continue drifting east along the Terneras vein to provide additional
confirmation of the ongoing lateral extension of the Terneras Vein. We
plan to also open a new drift to follow certain prominent veinlets
where we anticipate that these veinlets are in fact indicators of the
depth extensions of numerous old workings, which occur near the surface
above our working area.

All widths are true widths. Samples were assayed at the ERSA laboratory
in Torre�n, 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.

ECU Silver Mining Inc. is focused on the exploration, development and
mining of gold, silver and base metals at its Velarde�a District Properties
in Durango, Mexico. The area includes five historical mines - Santa Juana,
Terneras, San Mateo, San Juanes, and the San Diego mine. ECU is
defining the "Mineralized Corridor" at Santa Juana and also further
defining several higher grade narrow veins within the area. ECU's
mission is to become a pre-eminent silver producer through the
development of existing, and additional potential resources at
Velarde�a.
