MAG Silver Reports Deep Intersection of High Grade
      Silver on Valdeca�as 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%)) is pleased to announce assay results from the
Valdeca�as Vein for Hole GE. This hole was not included within the
resource estimate recently reported for the Valdeca�as 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 Valdeca�as 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 Valdeca�as 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 Valdeca�as Vein with the aim
of producing a 43-101 compliant resource report later in the year.

(See longitudinal section attached and 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 Pe�oles 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.

About the Joint Venture
The 8,000 hectare Juanicipio property is located in Zacatecas State,
Mexico just outside the mining town of Fresnillo. The Fresnillo mine
area has been in continuous production since the 1500's and today is
host to the worlds' largest producing primary silver mine operated by
Fresnillo plc Pe�oles. The Fresnillo/MAG Juanicipio Joint Venture lies
5 kilometres west from the principal production head-frame of the
Fresnillo Mine and 1.5 kilometres west from the Saucito Vein, currently
undergoing preproduction development with construction of a 600 metre
shaft and a 2,200 metre decline. MAG and Fresnillo are now operating
the delineation and exploration program through their joint venture
company, Minera Juanicipio S.A. DE C.V.

About MAG Silver Corp. ( )
MAG is focused on district scale projects located within the Mexican
Silver Belt. Our mission is to become one of the premier companies in
the Silver Mining Industry. MAG and its partner Fresnillo plc are

silver, lead and zinc discovery at its 100% owned Cinco de Mayo
property. MAG is based in Vancouver, British Columbia, Canada. Its
common shares trade on the TSX under the symbol MAG and on AMEX under
the symbol MVG.
