MAG Silver Provides Exploration Update for Salemex and Four Other Mexican Properties

June 5, 2009

Salemex: 2 metres of 4.77 g/t (0.14 opt) gold and 55 g/t (1.6 opt) silver and 0.5 metres of 10 g/t (0.29 opt) gold and 1,735 g/t (50.4 opt) silver

Vancouver, BC...MAG Silver Corp. (TSX: MAG; NYSE-A: MVG) ("MAG"), announces assay and geological results from initial and ongoing drill programs on five of its 100% owned properties in Mexico. Salemex, Lagartos SE and Lorena are epithermal vein systems, while Sierra Ramirez and Nuevo Mundo are Carbonate Replacement Deposits. Significant results are presented in the tables below. Both Salemex and Lagartos SE will require further drilling to follow up on encouraging gold and silver results.

SALEMEX, CHIHUAHUA: The property is cut by three major quartz veins ranging from 1 to over 25 metres wide that have seen minor historic mining and prospecting, but no significant drilling. Eight initial holes were drilled along 2 kilometres of bold vein outcrops at Salemex. The southernmost hole, SM-02, reported 10 grams per tonne (g/t) (0.29 ounces per ton (opt)) gold; 1,735 g/t (50 opt) silver; 3% lead and 1.6% zinc over 0.5 metre vein width. Hole SM-08, drilled 240 metres north of SM-02 reported 4.7 g/t (0.14 opt) gold; 55 g/t (1.6 opt) silver; 0.75% lead and 1% zinc over 2 metres. Significantly both of these intercepts are high-grade sulphide zones within a quartz-filled vein and breccia zone that ranges from 8 to over 25 metres wide. The remaining holes were drilled farther to the north or west and show a northward and downward progression into narrower overall vein width with diminishing gold and silver values contrasted by increasing lead and zinc values in skarn associated with an intrusive body. The Salemex Project lies about 35 kilometres northwest of Chihuahua City, just west of the Chihuahua-El Paso highway.

"We are pleased to see such a strong southward-increasing trend of precious metals values emerging from the first drill holes along this impressive looking vein system" said Dan MacInnis, President of MAG Silver. "The vein disappears under cover just to the southeast of Hole 2, but we can follow vein fragments for another 2 kilometres southward and will focus our next exploration phase in that direction."

SIERRA RAMIREZ: Sixteen holes have been drilled on a combination of geological and geophysical targets in the San Acacio and El Pavo areas where the bulk of historic high-grade silver production occurred at Sierra Ramirez, Durango. Drilling was primarily focused on seeking feeders to the historic limestone-hosted mantos and possible intrusions. Hole SRPV-05 cut 4,530 g/t (130 opt) silver with 0.86% copper over 1.5 metres at 150 metres depth along the contact between the district's principal limestone host unit and underlying Jurassic volcanic rocks. Minor additional silver, lead and zinc intercepts were made, but surprisingly fresh and unbroken volcanic rocks were found to underlie the projections of strong, well-mineralized high-angle structures that cut the surface limestones. Magnetic anomalies were found to correspond to the volcanic rocks and no intrusions were cut. Results are pending from the final 3 holes.

Geological and assay results indicate the Sierra Ramirez mantos were not fed directly from depth and currently potential lateral sources for the extensive high-grade historically mined orebodies are being evaluated.

LAGARTOS SE: Twenty eight holes have been drilled in four principal areas within, and along the projections of major vein systems in the historic Zacatecas District, which has produced over 1 billion ounces of silver. The major vein systems of the Zacatecas District are comprised by multiple (up to 40) parallel and braided veins many of which experienced multiple stages of mineralization. Many of the vein systems lie within major regional faults that slice across the district from southeast to northwest. Targeting has used a combination of surface mapping and airborne magnetic-electro-magnetic (AEM) geophysics to project major veins under cover into areas flanking the zones of historic mining, with the goal of finding entire new stretches of virgin mineralized vein. The Las Majadas-Pajarito Hill zone lies along the southeastern extension of the important northwest-trending Malanoche Vein System, which includes Capstone's San Roberto Mine. The La Luz, Predelicta and Veta Grande SE target areas lies along the important northwest-trending Veta Grande (Big Vein) which parallels the Malanoche Vein System some 3 kilometres to the north.

Las Majadas-Pajarito Hill Veins: To date, 19 holes have been drilled across a zone approximately 400 metres wide along nearly 1.5 kilometres of strike length to date. Overall results show a progressive northwest thickening of the veins and an increase in lead and zinc sulphide content. Silver and gold values are highest in the shallower vein intercepts, indicating that further drilling will target the veins at shallow levels.

Note: NSV = no significant value

La Luz Area: The La Luz lies along the alluvium covered north-western projection of the Veta Gande Vein system. There are no outcrops in the area, so drilling was targeted of projection of the vein system, a linear magnetic anomaly and geomorphological interpretation. Five holes were drilled, cutting between 100 and 250 metres of alluvium before reaching bedrock. Hole LL08-01 cut a 15 metre wide structure with pyrite-bearing calcite veinlets that were strongly anomalous in barium and weakly anomalous in copper and zinc. No significant structures were cut in the remaining holes. The depth of the alluvium is prohibitive of additional work in this area.

Predelicta: The Predelicta claim lies approximately 4 kilometres southeast of La Luz. The area covers about 500 metres of strike length within the northwestern historically mined portion of the Veta Grande Vein System. Three to five braided veins marked by workings and dumps cross the claim and 8 holes were drilled beneath the old workings. All holes cut sulphide-bearing quartz and calcite veins between 0.25 and 2.5 metres wide. Hole PR09-01 reported the best results with 1.77 g/t gold; 137 g/t (4 opt) silver, 0.12% copper; 2.4% lead and 2.2% zinc over 0.45 metres. The results indicate that the Bonanza zone was eroded away here and no immediate additional work is proposed here.

Veta Grande SE: The Veta Grande SE target area lies along the alluvium covered south-eastern projection of the Veta Grande Vein System. Like La Luz, there are no outcrops so drilling was targeted on a south-eastern projection of the principal Veta Grande vein and a coincident linear color anomaly. Alluvium was found to be less than 75 metres thick. Hole VGSE-01 cut a 30 centimetres quartz-calcite vein that reported 24.3 g/t (0.71 opt) silver and VGSE-02 cut a 50 metre wide zone of profound shearing and brecciation with anomalous zinc values. Initial indications are that these holes cut the major fault and a stringer vein in the footwall of the principal Veta Grande Vein. Drilling is slated to begin soon to seek the principal vein slightly farther to the south.

La Lorena: Lies 35 kilometres north of the famous 1.3 billon ounce silver producing Guanajuato Distict, along the northwest projection of the eastern El Cubo-Villalpando Vein system. Surface alteration and geochemistry at Lorena bear considerable geological resemblance to the area flanking the Fresnillo District where MAG has made its Juanicipio discovery. Lorena is dominated by a large open pit where an estimated 150,000 tonnes of very pure kaolinite and alunite were produced prior to 1990. This alteration is developed along a strong NW structural system marked by pervasive silicification with silver-arsenic-mercury anomalies. Six initial holes drilled from the northeast side of the principal structure, where MAG had obtained surface access for drilling. All cut narrow veinlets and silicified zones with anomalous gold (50-200 ppb); silver (3-10 ppm); lead (100-300 ppm) and zinc (100-450 ppm) values, but overall results indicate that the principal structure dips southwest and future drilling needs to be done from that side of the system. Negotiations to get surface access to test this are on-going.

Nuevo Mundo: Covers 11,762 hectares adjoining the eastern side of Canplats Camino Rojo discovery, southeast of the famous Concepcion del Oro-Penasquito District. Five short holes were drilled in isolated limestone exposures cut by strong gossan outcrops up to 8 metres wide and 200 metres long, reporting high mercury values. Three of the holes reported anomalous arsenic, mercury, antimony and zinc values. The majority of Nuevo Mundo is mantled by cover and work is on-going to develop targets in the more poorly exposed parts of this well located property.

Quality Assurance and Control: The Company has in place a quality control program to ensure best practices in sampling and analysis. Samples were collected by employees of consulting firm Minera Cascabel S.A. de C.V. on behalf of MAG Silver Corp. The surface rock samples are shipped directly in security sealed bags to ALS-Chemex Laboratories preparation facilities in Hermosillo, Sonora or Chihuahua City (Certification ISO 9001). Sample pulps are shipped from there to ALS-Chemex Laboratories in North Vancouver, Canada for analysis. All samples were assayed for gold by standard fire assay-ICP finish with a 50 gram charge. Gold values in excess of 3.00 g/t were re-analyzed by fire assay with gravimetric finish for greater accuracy. Silver, zinc, copper and lead values in excess of 100 ppm, 1%, 1% and 1% respectively are also repeated by fire assay.
