Significant New Gold Discovery of 15.31 Grams Gold Per Tonne Over 3.25 Metres on San Diego JV Property, Mexico


MONTREAL, QUEBEC and TORREON, MEXICO--(Marketwire - June 11, 2007) - Golden Tag Resources Ltd. (TSX VENTURE:GOG) ("Golden Tag") and ECU Silver Mining Inc. (TSX VENTURE:ECU) are pleased to report additional assay results from recent drilling on the San Diego property, Durango State, Mexico. New assay results include:

A new gold discovery in the Western Sector of 15.31 g/t Au over 3.25 meters in Hole SD-07-08, including, 38.7 g/t Au over 0.35 meter and 26.8 g/t Au over 1.10 meters.

Continuing indications of wider polymetallic mineralization associated to skarn replacement zones and sulphide rich stringer zone developed along contact areas:

La Cruz Vein:

- 1,130 g/t Ag with 2.89 % Pb over 0.30 m in Hole SD-07-09;

- 764 g/t Ag with 7.30 % Pb, 2.64% Zn over 0.45 m in SD-07-17

- 524 g/t Ag over 1.15 m in SD-07-16

La Rata Vein:

- 251 g/t Ag over 1.70 m in Hole SD-07-16

- 401 g/t Ag with 1.18% Zn over 0.30 m in SD-07-13;

Montanez Vein:

- 94 g/t Ag with 3.66% Pb, 6.39% Zn over 1.40 m in SD-07-16

- 348 g/t Ag with 1.84 % Pb, 0.75 % Zn over 2.05 m in SD-07-08

With an adjacent breccia zone returning:

- 142 g/t Ag over 7.35 m in Hole SD-07-08;

Continuing high grade assays of silver-lead-zinc in the narrow polymetallic veins of the Eastern Sector:

El Jal Vein:

- 1,380 g/t Ag with 3.21 % Pb, 10.2% Zn over 0.25 m in SD-07-13

Assays from an additional 600 samples are still outstanding at the laboratory and will be reported when received. Hole SD-07-08 was the last hole drilled on the property in the recent 17-holes program completed in May and represents proposed hole P4 of a 3-hole serie referred as P2-P3-P4 in a Press Release dated April 18, 2007. All three holes (SD-07-16, -17 and -08) were aimed at testing the western extensions of the Montanez, La Rata and La Cruz Veins.

Gold mineralization encountered in hole SD-07-08 is hosted in a Green skarn unit occurring within a wide phyllic-argillic altered monzonite sill. Mineralization strictly consists of disseminated cubic pyrite and, as such, differs greatly from the typical high grade silver (Ag), lead (Pb) and Zinc (Zn) mineralization encountered to date at San Diego. This gold mineralization intersected at depth, constitutes yet an additional style of mineralization indicative of epithermal activity associated with the altered monzonite. The new Gold zone remains open in all directions and additional drilling will be needed to further assess the potential of this new zone but for now, it is extremely encouraging as it brings evidence of a high grade gold potential at San Diego.

The JV partners are very encouraged by the style and variety of mineralization on the property intersected in the 6,500-meters drilling program. Brief conclusions from the program include the following observations:

- The property is cored by a central Diorite intrusion which is associated with skarn-type alteration along contact areas with the hosting limestone. Skarn alteration is particularly well developed west of the Diorite;

- A major NNE fault trending across the property cuts the northwestern contact of the Diorite. This intrusive has not been observed to the west of the fault, however additional drilling may indicate that it occurs further at depth in the Western sector;

- A WNW-ESE and steeply north-dipping Monzonite sill transects the property. This sill varies greatly in width from 40 to over 100 meters and commonly exhibits propylitic-phyllic and argillic alterations. Its relationship with the Diorite is not known at this stage but it could represent a more differentiated offshoot of the central intrusion;

- Laterally extensive and high grade Ag-Zn-Pb veins are dominantly East-West and WNW-ESE trending across the property, cutting all rock types. The Montanez, Cantarranas and El Jal (a rarer NE trending vein) located in the Eastern Sector - that is, to the east of the NNE Fault - are high grade, narrow veins. These Veins generally dip steeply North or South with the Montanez vein paralleling the contact of the Monzonite sill and occurring in association with broader and lower grade Ag-Pb-Zn stinger zones within the altered sill (see Hole SD-07-12 in PR of April 2007);

- Laterally extensive and high grade Ag-Zn-Pb veins to the west of the Diorite are represented by the La Cruz, La Rata and the Montanez Veins. The La Rata vein represents a linking structure, cross-cutting the Monzonite sill between the western termination of the Montanez vein and the eastern termination of the La Cruz Vein. Drilling to date reveals good vein continuity but greater grade/width variations for these veins. Drilling information also showed that the La Rata/La Cruz and Montanez Veins are associated to wide mineralized Fault Corridors where stringer-style sulphide mineralization is related to intense microfracturation and contact effects between closely spaced exoskarn and monzonite units. The Gold Zone intersected in hole SD-07-08 bears some similarities to this environment with a host rock consisting of a green skarn interval injected by monzonite dykelets;

- The Central portion of the property represents a truly interesting sector. This area, lying immediately to the west of the Diorite faulted contact, appears to coincide with a triple-junction point where the Rata and La Cruz Vein structures are intersecting with the NE Fault. Significant skarn-type alteration (endo- and exo-skarns), silica-sericite-allunite alteration in Monzonite, with strong and widespread stringer and disseminated mineralization occur in complex inter-association. Interpretation of this complex area suggests there is potential at depth for Skarn-related massive sulphide replacement bodies, Mantos-type massive sulphides and, with the new gold zone, good potential to extend this mineralization throughout this area at depth.

A compilation and re-interpretation of the acquired data will be undertaken prior to additional drilling in late summer. An updated 43-101 compliant Resource estimate will be calculated. A Presentation and photos of the San Diego project is available at

Quality Control:

The San Diego drilling program is supervised by Ms. Kateri Marchand, P.Geol. and Qualified Person under National Instrument 43-101 guidelines and has confirmed all disclosures in this release. Assay samples are taken from NQ/BQ size drill core cut in half with one half sent to a commercial laboratory and other half retained for future reference. All the samples represent the core length and may not be representative of the true width. A strict QA/QC program is followed which includes mineralized standards and blanks for each batch of samples. Analyses were performed by ALS Chemex accredited assay laboratories of Guadalajara (Mexico) and Vancouver (Canada). Check samples are also sent to SGS assay laboratory of Durango (Mexico).

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