ECU Silver Announces New Assays at its Chicago Property in
Mexico.
======================================================================
Highlights:
ECU announces assays of 10g/t Gold, 977g/t Silver, 26% Lead, 3.6% Zinc
and 0.6% Copper over 0.49 meters.
TORONTO ONTARIO, July 18, 2007 - ECU Silver Mining Inc. (TSX: ECU) is
pleased to report recent assay results from the first phase of the
exploration drilling work conducted at the Company's Chicago Property
which consisted of drilling six holes totaling 4,101 meters. The
Chicago Property is located less than 500 meters south from the
Company's Velarde�a Property boundary. On surface, several veins are
well identified, varying in known length from 250 meters to 1,300
meters and in width from 0.20 to 6.0 meters. The best known vein, the
Los Muertos - Chicago Vein (the "Chicago Vein"), has historically been
followed for 1,300 meters horizontally including underground
development for 390 meters horizontally and 240 meters vertically.
The primary purpose of the first phase of the drilling program on the
Chicago Property was to confirm the continuity of the Chicago Vein at
depth, below known cuts or intercepts. This press release outlines
certain assay results from six drill holes labeled CH-07-01 to
CH-07-06.
LOS MUERTOS - CHICAGO VEIN
The first drill hole (CH-07-01) did not reach the projection of the
Chicago Vein because of technical difficulties. The results of the five
other drill holes are presented in Table 1 below.

The deepest intercept was in drill hole CH-07-02 at a vertical depth of
556 meters and all intercepts were below the 300 meters level.
Considering the normal variability of this type of vein, all intercepts
were significant and exhibited good to excellent values in gold,
silver, lead and zinc and represented cuts in the thin portions of the
Chicago Vein. No "chimney" type zones were encountered which is
considered normal given the limited lateral extension of these portions
of the Chicago Vein, which are normally 15 to 50 meters in length with
widths of 1.0 to 6.0 meters.
With this drilling, the Chicago Vein has now been confirmed at depth by
drill holes or underground development, over a strike length of 850
meters of the total 1,300 meters followed on surface. It has also been
confirmed that the Chicago Vein continues to a depth of 560 meters and
likely goes significantly deeper as the grades encountered in the
deepest cut are amongst the best assayed from that vein.
OTHER VEINS
Several other veins were cut in the various drill holes, including the
San Agustin vein in hole CH-07-01. However at this stage, it was the
only intercept that could be interpreted with any degree of certainty.
Further drilling, surface mapping and geological modeling might allow
for a better interpretation and confirm continuity for some of these
intercepts. This work will be part of the second phase of exploration.
The assay results from these cuts are presented in Table 2 below.

Assays from these intercepts confirm the presence of several veins with
metal contents that justify further work. The next step will be to
properly position these veins in relation to one another and plan the
in-fill drilling of the second phase of exploration in such a way as to
define the continuity of these veins.
Michel Roy, chairman and CEO states "The Chicago Property is showing
very encouraging results which will enhance the overall mineral
resource being defined at our Velarde�a Property where we are
continuing our drilling and development work at Santa Juana and San
Mateo. We continue to advance our exploration work and expect positive
results on both the Chicago and Velarde�a properties with our ongoing
exploration program."
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.
