MAG Silver Reports Deep Intersection of

High Grade Silver on Valdecañas Vein

1,179 grams per tonne (g/t) (34.4 ounces per ton (opt)) silver, 1.98 g/t gold,

3.01% lead and 2.21% zinc over 4.71 metres (true width)

Vancouver, B.C…MAG Silver Corp. (TSX: MAG) (AMEX: MVG) (“MAG”)on behalf of Minera Juanicipio SA (a joint venture between Fresnillo plc (56%) and MAG (44%)) ispleased to announce assay results from the Valdecañas Vein for Hole GE.  This hole was not included within the resource estimate recently reported for the Valdecañas Vein (see press release dated June 18, 2008).

Hole GE intersected two veins separated by 10 metres of altered and veined wall rock. The upper gold rich vein reports as 123 g/t (3.6 opt) silver, 4.89 g/t gold, 1.24% lead and 4.92% zinc over 7.38 metres (true width). This includes a higher grade intercept of 166 g/t (4.8 opt) silver, 5.89 g/t gold, 1.42% lead and 6.42% zinc over 3.0 metres (see longitudinal section attached). The lower silver rich vein has returned 1,179 g/t (34.4 opt) silver, 1.98 g/t gold, 3.01% lead and 2.21% zinc over 4.71 metres (true width). This also includes a high grade gold and silver intercept of 6,310 g/t (183.9 opt) silver, 10.05 g/t gold, 7.63% lead and 5.23% zinc over 1.0 metres.

Hole GE is one of the deepest holes to test the Valdecañas Vein to the west and this intersection remains open down dip

“We are extremely pleased with these results because they indicate the continuation of the high grade silver and gold to depth in the western part of the Valdecañas Vein”, said Dan MacInnis, President and CEO of MAG Silver.

The results reported here are part of a 25,000 metre drill program being carried out on the Juanicipio property in 2008. The bulk of the drilling is directed towards defining the Valdecañas Vein with the aim of producing a 43-101 compliant resource report later in the year.

(See longitudinal section attached and www.magsilver.com for diagrams).

Drilling continues with four drills currently operating.  MAG and Fresnillo operate the project at Juanicipio through their joint venture company, Minera Juanicipio S.A. DE C.V.  MAG holds a 44% interest in the Juanicipio Joint Venture. In a press release dated June 18, 2008 (investors should refer to this press release for disclaimer information regarding resources) the joint venture announced a total inferred resource estimate of 237.8 million ounces of silver of which MAG’s 44% interest equates to 104.5 million ounces and Fresnillo’s 56% interest equates to 133.2 million ounces. In addition to the silver the estimate reports the inferred resource also contains a total of 480,000 ounces of gold and almost 1 billion pounds of combined lead and zinc (457,700 tonnes).

Quality Assurance and Control: The samples are shipped directly in security sealed bags to ALS-Chemex Laboratories preparation facility in Guadalajara, Jalisco, Mexico (Certification ISO 9001). Samples shipped also include intermittent standards and blanks. Pulp samples are subsequently shipped to ALS-Chemex Laboratories in North Vancouver, Canada for analysis. Two extra pulp samples are also prepared and are analyzed (in progress) by SGS Laboratories (Certification ISO 9001) and Inspectorate Laboratories (Certification ISO 9001) (or other recognized lab). The bulk reject is subsequently sent to CIDT (Center for Investigation and Technical Development) of Peñoles in Torreon, Mexico for metallurgical testing where a fourth assay for each sample is analyzed and a calculated head grade is received on the basis of a concentrate balance. The CIDT also does a full microscopic, XRF and XRD mineralogical analysis.

Qualified Person: Dr. Peter Megaw, Ph.D., C.P.G., has acted as the qualified person as defined in National Instrument 43-101 for this disclosure and supervised the preparation of the technical information in this release. Dr. Megaw has a Ph.D. in geology and more than 20 years of relevant experience focussed on silver and gold mineralization, and exploration and drilling in Mexico. He is a certified Professional Geologist (CPG 10227) by the American Institute of Professional Geologists and an Arizona registered geologist (ARG 21613). Dr. Megaw is not independent as he is a Director and Shareholder of MAG and is a vendor of one project, other than Juanicipio, whereby he may receive additional shares. Dr. Megaw is satisfied that the results are verified based on an inspection of the core, a review of the sampling procedures, the credentials of the professionals completing the work and the visual nature of the silver and base metal sulphides within a district where he is familiar with the style and continuity of mineralization.
