MAG Silver Reports Discovery of New High Grade Encino Vein at Juanicipio

1,843 g/t (53.7 opt) silver, 4.43 g/t gold, 3.54% lead and 5.96% zinc over 3.41 metres

Vancouver, B.C...MAG Silver Corp. (TSX:MAG) (NYSE-A:MVG) ("MAG") has been advised by the operator of the Juanicipio Joint Venture that a new high grade vein appears to have been discovered as a result of detailed drilling in the vicinity of the Valdecañas Vein. Re-interpretation of a previously reported intersection of high grade gold and silver in Hole JI-06-IE, (1,843 grams per tonne (g/t)) (53.7 ounces per ton (opt)) silver, 4.43 g/t gold, 3.54% lead and 5.96% zinc over a true width of 3.41 metres (see press release dated June 12, 2007) shows that this is a new and separate north-dipping vein named the "Encino". The Encino Vein lies in the hanging wall about 200 metres above the south dipping Valdecañas Vein and dips back towards it (see section attached and for diagram).

The Encino Vein was not previously recognized because initial drilling in the area, directed at the Valdecañas Vein, was either parallel to and/or in front of this structure. Earlier interpretations concluded that the intersection in Hole JI-06-IE was the down-dip extension of the Valdecañas Vein, but subsequent nearby intercepts of the Valdecañas Vein show that such geometry is improbable. In addition this new interpretation indicates that JI-06-IE did not intersect the Valdecañas Vein, so the Valdecañas Vein at this time remains open down-dip on section I.

Similar, closely-spaced vein sets with opposing dips are common in the overall Fresnillo Silver district. The Encino Vein appears open along strike in both directions and its intercept with the Valdecañas Vein provides an excellent exploration target.

The Encino Vein features prominently in the 2009 proposed exploration program presented at a recent Minera Juanicipio SA Technical Committee by Fresnillo plc, the operator of the Juanicipio Joint Venture. In order to test and assess this preliminary interpretation of the "Encino Vein", the project operator has allocated 8,000 metres of drilling from a proposed 25,000 metre program for 2009. The objective of the 2009 drill program will be to confirm and follow up on the Encino Vein as well as to further explore the Valdecañas Vein, Juanicipio Vein, and other drill targets. The 2009 preliminary budgeted program is subject to approval by the board of Minera Juanicipio, the 56%/44% Fresnillo / MAG Joint Venture Company. A full board meeting is scheduled for late January.

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.
