Golden Tag Resources Ltd. and ECU Silver Mining Inc.: Discovery of a New Polymetallic Skarn Environment at San Diego, Mexico

MONTREAL, QUEBEC--(Marketwire - March 3, 2008) - Golden Tag Resources Ltd. (TSX VENTURE:GOG) ("Golden Tag") and ECU Silver Mining Inc. (TSX:ECU) ("ECU") are pleased to report additional diamond drill hole results from its exploration program initiated in October 2007 on the San Diego property, Durango State, Mexico. Final results from two additional holes, SD-07-20 and SD-07-22, drilled on the eastern flank of the central Dioritic Intrusion, continue to expand mineralization associated with the Montanez Vein and confirm the presence of extensive new zone s of Green Skarn hosting Silver-Lead-Zinc mineralization. The two holes confirm:

- Presence of wide zones of mineralized green skarn (Exoskarn). Previous drilling encountered wide zones of mineralization in Endoskarns associated with microfractured and altered intrusive rocks such as diorite and monzonite. This is the first time that wide zones of limestone hosted alteration and mineralization (exoskarns) have been encountered.

- Extensive nature of mineralization at depth around the central Diorite Intrusion and the Monzonite sill in the immediate footwall to the Montanez Zone. Hole SD-07-22 encountered mineralization over the last 150 metres of the hole within altered limestone (marble and exoskarns) and altered monzonite (endoskarns). The true thickness of the skarn is estimated to be 40 metres and metal content improves at depth from hole -20 to hole 22.

- Large diversity of mineralized environments at San Diego that goes well beyond the initial high grade - narrow vein type of mineralization that attracted the attention of the JV partners.

Results from the two recently reported holes in the footwall to the Montanez Vein and conversion factors used to convert to silver equivalents are shown in Table 1. Highlights include:

HOLE SD-07-20

- High Grade Ag Stringers north of the Montanez Vein

-- 344 g/t Ag over 1.51 metres (m) with 1.30% Lead (Pb) and 2.41% Zinc (Zn) (Ag+Ag Equiv. 456 g/t Ag) in hole SD-07-20 from 154.18 to 155.69 m.

-- 4,420 g/t Ag over 0.58 m with 5.26% Pb and 7.11% Zn (Ag+Ag Equiv.
4,782 g/t Ag) in hole SD-07-20 from 164.60 to 165.18 m.

- Mineralized Green Skarn in Footwall to, and north of the Montanez Vein

-- 231 g/t Ag over 2.45 m with 0.60% Pb and 1.07% Zn (Ag+Ag Equiv.
280 g/t Ag) in hole SD-07-20 from 195.91 to 198.36 m.

HOLE SD-07-22

- High Grade Ag Stringers north of the Montanez Vein

-- 628 g/t Ag over 1.55 m with 6.00% Pb and 8.07% Zn (Ag+Ag Equiv.
1,039 g/t Ag) in hole SD-07-22 from 226.67 to 228.22 m.

- Mineralized Green Skarn in Footwall to, and north of the Montanez Vein

-- 104 g/t Ag over 8.03 m with 3.36% Pb and 2.50% Zn (Ag+Ag Equiv.
271 g/t Ag) in hole SD-07-22 from 437.37 to 445.40 m, including:

--- 88 g/t Ag over 3.06 m with 2.25% Pb and 2.72% Zn (Ag+Ag Equiv.
233 g/t Ag) from 437.37 to 440.43.22 m, and,

--- 144 g/t Ag over 3.47 m with 5.11% Pb and 2.98% Zn (Ag+Ag Equiv.
373 g/t Ag) from 441.93 to 445.40 m.

-- 44 g/t Ag over 3.78 m with 1.25% Pb and 1.53% Zn (Ag+Ag Equiv. 125 g/t Ag) in hole SD-07-22 from 478.35 to 482.13 m.

-- 38 g/t Ag over 5.69 m with 1.46% Pb and 1.27% Zn (Ag+Ag Equiv. 116 g/t Ag) in hole SD-07-22 from 498.52 to 504.21 m.

David Rigg, CEO Golden Tag stated that "Phase 3 exploration drilling to date has confirmed the existence of broad zones of mineralization at depth on the property. The additional new discovery of a mineralized Green skarn environment as part of the system of mineralized veins and intrusion related zones provides additional support that the property hosts a strong and substantial mineralizing system related to the central Diorite and the Monzonite Sill. Several areas on the property have been confirmed to contain broad and continuous zones of mineralization and offer large upside potential to resources from the delineation of bulk tonnage zones laterally and at depth."

Holes SD-07-20 and -22:

SD-07-20 targeted the Montanez Vein at 150 m below surface whereas SD-07-22 targeted the vein 300 m below this, at a vertical depth of 450 m. Both holes failed to reach the Montanez Vein and the Hangingwall Zone due to technical drilling problems caused by fault zones. Holes -20 and -22 intersected a marble section hosting several isolated thin sulphide stringers bearing galena-sulfosalts mineralization. Assay grades as high as 4,420 g/t Ag over 0.58 m have been returned from this area. The silver-rich stringers are best developed in hole -20, where deformation is not as intense as in hole -22. The stringer system can be projected 100 to 150 metres to the west into the Diorite Stock in holes SD-06-09 and 06-10 respectively. This area also hosts the Cantarranas Vein recognized in previous drilling.

The new Green Skarn Zone is located down-hole of the stringer zone, and in the immediate footwall of the northwest-southeast trending Monzonite Sill. It consists of a broad interval of argillic-silica altered limestones with centimetric, massive sulphide stringers of pyrite-galena-sphalerite with associated chlorite-hematite alteration. Central to this zone and widening to depth is a second altered and mineralized monzonite sill. Visual indications and assay grades from the two holes confirm an increasing metal content to depth associated with more intense alteration and deformation. SD-07-22 cuts a 33-m long zone (11 metre estimated true width) of Green skarn wedged between the Central Diorite intrusive and the Monzonite Sills, the association of which may explain the increasing quality of the deformation-alteration and resulting mineralization at depth. This trend and the apparent greater complexity of the Monzonite and Diorite at depth, are very encouraging for future drilling and the deeper potential in the system.

The current budget will be increased to 8,000 m of drilling to complete three additional drill holes from a drill station to the south. Road construction in this area is well advanced. This drilling will further evaluate the Footwall zones and complete testing of the Hanging wall and principal Montanez Vein in this area.

Golden Tag Resources and ECU initiated the Phase 3 drilling program in October 2007 with the objective of expanding recently evaluated Mineral Resources on the property and improving resource quality in several areas of the Resource. To date, a total of 5,500 metres of drilling has been performed. Assay results have been returned from only 4 of the 15 holes completed.

Quality Control:

The drilling program is supervised by Ms. Kateri Marchand, P.Geo. and Qualified Person under National Instrument 43-101 guidelines and she 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. 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).

San Diego Mineral Resources

Mineral Resources on the San Diego property from Phase 1 and 2 drilling completed in May, 2007, were estimated to be 370,852 Tonnes grading 245 g/t Ag, 1.80% Pb, 1.33% Zn & 0.339 g/t Au for a total of 3,979,526 ounces silver equivalent in the Indicated category; and 4,976,461 Tonnes grading 167 g/t Ag, 1.25% Pb, 1.26% Zn & 0.163 g/t Au for a total of 38,403,639 ounces silver equivalent in the Inferred category (See Press Release Jan 28, 2008). The Resource Estimate was completed by Kateri Marchand, P.Geo, Exploration Manager on the San Diego Project, and independently audited and verified by William J. Lewis, P.Geo, MICON International Ltd., qualified persons as defined under NI 43-101 guidelines. Silver equivalency is calculated using the same commodity prices and metal recovery factors used in the San Diego 43-101 Resource Estimate Report: Details are provided in footnote to Table1. Readers are cautioned that until a pre-feasibility study is completed, there are no assurances that these mineralized zones will be economically viable.

Silver Equivalents were calculated using the same commodity prices and metal recovery factors used in the San Diego 43-101 Resource Estimate Report: 26.60 g/t Ag per 1% Pb, 31.21 g/t Ag per 1% Zn. Recovery factors were 76% for silver, 71% for gold, 75% for lead and 44% for Zn. Commodity prices of US$11.60/oz for silver,US$0.60/lb for lead and US$1.20lb for zinc were used. Gold content was not taken into account in the silver equivalent calculation. The true thickness of the intersections has not yet been determined; intervals in table are based on core lengths.
