ECU Silver announces new assays from Level 18 within the
Mineralized Corridor at the Santa Juana Mine
======================================================================

TORONTO ONTARIO, March 30, 2007 - Mr. Michel Roy, Chairman and CEO of
ECU Silver Mining Inc. (TSX-V: ECU) is pleased to announce the Company
has received assays from several new cuts within the Mineralized
Corridor (the "MC") on level 18 of the Santa Juana mine (first reported
in the Company's press release dated December 18, 2006).

Highlights are:

.. Seven cross-cuts yielding an average of 2 g/t gold, 90 g/t silver,
0.22% lead, 0.49% zinc and 0.21% copper over 19.8 meters (65 feet) of
width and 250 meters (820 feet) of length.

.. Results Included:
- Cut 18-045 that averaged 2.84 g/t gold, 108 g/t silver over 10.85
meters (35.5 feet) of width;
- Cut 18-090 intercept that averaged 19.33 g/t Gold and 159 g/t silver
over 2.3 meters (7.54 feet) of width;
- Cut 18-190 intercept that averaged 2.36 g/t gold, 204 g/t silver
over 4.18 meters (13.7 feet) of width;
- Cut 18-215 intercept that averaged 1.26 g/t gold, 159 g/t silver
over 20.64 meters (68 feet) of width.

Level 18 Cross-Cuts

The recent development and exploration work on level 18 consisted of
driving new cross-cuts from a new access drift and connecting these
access drifts to the Company's previous development and exploration
work on the west side of the Tres Aguilas fault. The primary purpose of
these workings was to gather further information to enable the Company
to continue building its data base on the MC which will ultimately be
used by the Company in assessing possible future production plans.

The most recent work completed shows two options will be considered for
bulk mining. The first will consider mining the MC over its entire
width as one mining unit and the second to mine packages of veins that
show lateral and vertical continuity within the MC. Economic models
will be built for both scenarios in order for the Company to choose the
most economically effective option.

To better orient the reader, the MC strikes in a north-west to
south-east direction with cross-cuts driven in a north-east to
south-west direction which cut perpendicular to the strike of the MC.
"Cross-cuts" differ from "cuts" in that the cross-cuts contain wall
samples whereas cuts also include drill-hole data.

See table 1 below for assay results.

Significance of level 18 cross-cuts

The results shown below confirm the continuity of high grade
mineralized packages within the MC for 250 meters laterally. The
Company is proceeding with more cuts to verify other packages within
the above mentioned 250 meters. In addition, more cuts are planned for
a further 120 meters extending north-west from the westerly most
section of the MC and a further 45 meters extending south-east from the
easterly most section of the MC. Once this is completed, the
information necessary to calculate resources blocks for the MC and/or
the high grade mineralized packages within the MC for level 18 will
have been gathered, analyzed, and reported to shareholders in a timely
manner.

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

Cut #18-045

Cut #18-045 is the eastern most cut completed on level 18 so far,
further delineating the eastern extension of the MC at level 18. Cut
#18-045 includes drill hole SJ 18-09 and continues to confirm the
lateral extent of the MC with excellent results in the portion opened
so far, namely 2.84 g/t gold, 108 g/t silver, 0.33% lead, 0.81% zinc
and 0.76% copper over 10.85 meters. The Company's development and
exploration are continuing in the eastern extent of the MC on level 18.

Cross-cut #18-090

Cross-cut #18-090 (initially reported on January 26th and also February
14th), is driven 45 meters north-west of #18-045 and is only 20 meters
north-west of the downward projection of the level 17.5 stockwork. The
interpretation of the veins package yielded three intercepts of
interest that can be correlated within nearby cross-cuts.

Cross-cut #18-113

Cross-cut #18-113 is driven 23 meters laterally further north-west from
cross-cut 18-090. The interpretation of the packages in this cross-cut
delineated two packages with high grades from both walls of the
cross-cuts.

Cut #18-150

Cut #18-150 is located 37 meters north-west of cross-cut #18-113. It
includes a short portion of drift and a cut from drill hole SJ 18-05 to
yield a total of 2.37 g/t gold and 55 g/t silver over 16.72 meters.

Cross-cut #18-190

Cross-cut #18-190 is 40 meters north-west of cut #18-150 and was driven
120 meters north-west of the downward projection from our original
level 17.5 stockwork zone discovery as reported by the Company in April
of 2006. The interpretation of the veins package yielded three
intercepts of interest that can be correlated within nearby cross-cuts.

Cross-cut #18-215

Cross-cut #18-215 is a new drift that was also designed to reach a
position which would facilitate the downward continuation of the
internal Santa Juana shaft from level 17 to level 18. The Company will
prepare two loading pockets on level 18 and a second holding bin on
level 12 to double the current hoisting capacity of the internal Santa
Juana shaft. While driving this drift, an important package of veins
was cut which yielded very interesting results of 1.26 g/t Au and 159
g/t Ag over 20.64 meters to date. This cross-cut will continue for
another 35 meters.

Hole SJ 18-07

Drill hole SJ 18-07 was drilled on section 295 to cut the package of B
veins. Again good results were obtained.

"We will continue to see more explorations results in the coming weeks
and months ahead as we have five drills operating on our properties. On
the Velardena property we have two drills at Santa Juana and one drill
at San Mateo. We have one drill on the San Diego property and one drill
on our Chicago property. We look forward to announcing our assay
results as they become available." Reports Michel Roy, Chairman and
CEO.

Furthermore, the Company wishes to announce that Mr. David Hu has
resigned from the ECU board of directors. Mr. Hu has been a large
supporter of ECU's growth strategy. Mr. Hu will focus his attention to
his role as Managing Partner of IIG Capital and provide customized
financing solutions to international companies including ECU. The
Company wishes to thank Mr. Hu for all of his efforts and contributions
he made and wishes him all the best in his future endeavors.

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. Samples were also assayed at the SGS laboratory in Durango,
Durango State, which is a certified laboratory. Property specific
quality control samples were inserted at regular intervals in the
sample sequence and the Company routinely does check assays at other
certified laboratories.

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