Notes:

(1) Mineral resources are not mineral reserves and do not have demonstrated economic viability. All figures rounded to reflect the relative accuracy of the estimates.

(2) Reported at a cut-off of 4.0 grams per tonne (g/t) gold equivalent using metal prices as follows: Gold $562/oz, Silver $10.40/oz, Lead $0.68/lb, Zinc $ 1.16/lb.

(3) Valdecañas resources reported in table above are attributable resources reflecting M. Juanicipio’s 100% ownership of the Juanicipio Joint Venture. MAG holds a 44% interest in M. Juanicipio.

SRK Consulting (Canada), Inc. (“SRK”) has been commissioned by MAG to prepare an updated technical report for the Valdecañas deposit.  The Company plans to file a report on the resources in accordance with Canadian National Instrument 43-101 within 45 days. National Instrument 43-101 is a rule developed by the Canadian Securities Administrators which established standards for certain public disclosure of scientific and technical information concerning mineral projects. The requirements of National Instrument 43-101 are not the same as those of the SEC.

Resource Estimation Detail

Mineral resources for the Valdecañas Vein have been estimated by Fresnillo personnel and audited by SRK. The mineral resource estimate for Valdecañas was prepared with Datamine Studio using a geostatistical block modeling approach. The resource model is based on drilling, sampling and assaying data that was acquired by competent personnel using industry best practices procedures (for information regarding Quality

Assurance and Control and Data Verification see previous press releases dated April 16, 2008 and December 20, 2007). At Valdecañas two vein structures were interpreted from 27 boreholes over a strike length of 1,600 metres on 200 metre sections. Capped metal grades were interpolated into a block model constrained by wireframes using an inverse distance algorithm with estimation parameters determined from experience in the district as there is insufficient data to model reliable variograms. The mineral resources were classified according to the JORC Code (2004 edition) primarily on the basis of distance from the nearest sample. SRK reviewed the methodology and procedures used by Fresnillo to estimate and classify the mineral resources for Valdecañas. The estimation procedures meet industry best practices. Visual sectional inspection by SRK of drill composite data compared against block model values for each metal type shows that block model values reflect input composite data.  SRK considers that all mineral resources at Valdecañas are appropriately classified as Inferred Mineral Resources. SRK also considers that infill drilling at Valdecañas on 100 metre sections will increase the confidence in the geological and grade continuity of the vein mineralization and allow better variography. The audited mineral resource statement for Valdecañas deposits as at 31 December 2007 is presented in the above table at a cut-off grade of 4.0 g/t of gold equivalent. The cut-off grade used to report mineral resources is considered by SRK to be appropriate.

Qualified Person

Mineral resources for the Valdecañas Silver Deposit have been estimated by Fresnillo personnel and audited by SRK under the supervision of Dr. Jean-Francois Couture, P.Geo (APGO#0197) and Mr. Glen Cole, P.Geo (APGO#1416). By virtue of their education and relevant experience Dr. Couture and Mr. Cole are Qualified Persons for the purpose of National Instrument 43-101. Dr. Couture and Mr. Cole are employees of SRK and are independent of MAG. The mineral resources have been classified in accordance to JORC (2004 edition). Under CIM Definition Standards for Mineral Resources and Mineral Reserves, (December 2005), the mineral resources for the Valdecañas deposit would be identical.

Information Concerning Estimates of Mineral Resources

This news release uses the term 'inferred resources’. MAG advises investors that although this term is recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), the U.S. Securities and Exchange Commission does not recognize this term. Investors are cautioned not to assume that any part or all of the mineral deposits in this category will ever be converted into reserves. In addition, 'inferred resources' have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for Preliminary Assessment as defined under Canadian National Instrument 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.

MAG Silver Reports Further

High Grade Silver on Valdecañas Vein

1,198 grams per tonne (g/t) (34.9 ounces per ton (opt)) silver, 0.24 g/t gold,

2.75% lead and 5.15% zinc over 4.70 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 Holes QE and QD (see the table below for details). Visual results are also provided for Holes GE and OF.  Holes GE, OF, QE and QD were not included within or are outside of the resource estimate recently reported for the Valdecañas Vein (see press release dated June 18, 2008).  Hole QE is important as it is the first hole to intersect the vein in the critical east central area which has limited drill information (see details below).

Hole QE intersected 1,198 g/t (34.9 opt) silver, 0.24 g/t gold, 2.75% lead and 5.15% zinc over 4.70 metres (true width).  This includes a higher grade intercept of 1,820 g/t (53.1 opt) silver, 0.16 g/t gold, 4.01% lead and 6.74% zinc over 2.82 metres (true width). Hole QE has now begun to fill in the central portion of the eastern half of the Valdecañas vein where there had previously been a significant gap between drill intercepts. This new hole pushes the high grade “bonanza” zone to almost 400 metres east of the discovery section “M” (see longitudinal section attached).

Hole QD reports an intersection of 200 g/t (5.8 opt) silver, 0.58 g/t gold, 0.03% lead and 0.01% zinc over 0.69 metres (true width).  Hole QD deviated dramatically and intersected the vein almost 250 metres west and 80 metres higher than its proposed target position (see longitudinal section attached). As a result, Hole QD intersected the Valdecañas Vein near or past the top of the “bonanza” zone as evidenced in part by the low base metal content.

“The high grade intersection of the Valdecañas Vein by Hole QE is a very important intercept for the Juanicipio Joint Venture”, said Dan MacInnis, President and CEO of MAG Silver, “It fills in a major gap of almost 500 metres between previous intercepts on sections M and S. Because of ground conditions, and access restrictions, we have had difficulty drilling in this area.  With the completion of Holes QE and OF (see below) we are beginning to define the eastern portion of the Valdecañas Vein”.

In addition to the above, Holes GE and OF have now been completed and await assay results. Hole GE intersected 14.9 metres (core length) of the Valdecañas Vein in two separate veins. The upper vein is 7.0 metres wide and the second vein is 7.9 metres wide. The two veins are separated by 3.5 metres of sedimentary host rock containing abundant quartz veinlets.  This hole is located on section “G” on the west end of the Valdecañas Vein and is 45 metres deeper than the intersection reported in Hole GD.

Hole OF also intersected the critical east central part of the Valdecañas Vein. The hole is reported to have intercepted 5.0 metres of vein. True position of the hole is yet unknown pending actual survey data.

Hole #	From	To	Width	Silver	Silver	Gold	Lead	Zinc	True
			metres	g/t	opt	g/t	%	%	Width
JI-08-QE Valdecañas  Vein	579.15	584.15	5.00	1,198	34.9	0.24	2.75	5.15	4.70

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

Drilling continues with four drills currently operating.  The results reported above 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.

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.

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 Peñoles. 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.
