MAG Silver Corp. (TSX:MAG)(NYSE Alternext US:MVG) ("MAG") reports assay results received from the Juanicipio property operator, Fresnillo plc, from recent definition drilling along the Valdecanas Vein. The three holes reported here were started in early 2009 and completed in February, 2009. The best result from this latest drilling is a high grade gold and silver intercept recorded in Hole PD which returned 2.72 metres (true width) of 1,578 grams per tonne (g/t) (46 ounces per ton (opt)) silver, 5.65 g/t gold, 5.94% lead and 6.67% zinc. This is part of a wider intercept which recorded 1,021 g/t (29.7 opt) silver, 3.32 g/t gold, 4.79% lead and 7.20% zinc over 4.71 metres (true width). Hole PD intersected the Valdecanas Vein almost 40 metres west of Hole QF and confirms the continuity of high grade silver and gold in this area on the eastern half of the Valdecanas Vein.

Hole RC was drilled to test the up dip potential along the eastern segment of the Valdecanas Vein where the top of the Bonanza Zone remains poorly defined by earlier drilling. Hole RC returned 660 g/t (19.2 opt) silver, 2.45 g/t gold, 0.24% lead and 0.42% zinc over 4.15 metres (true width). This included a higher grade gold and silver zone of 1,348 g/t (39.3 opt) silver, 5.14 g/t gold, 0.46% lead and 0.71% zinc over 1.93 metres (true width). At 450 metres below surface this intercept is the shallowest well mineralized vein intercept in the 600 metres stretch between section "Q" and the eastern property boundary (Section "T"). The low base metals are in keeping with expectations for the upper part of the vein. The excellent width and high grade gold and silver grades indicate that the top of the Bonanza Zone is still open up dip. More drilling will be required to fully define the top of the Bonanza Zone along the eastern half of the Valdecanas Vein.

Hole KF intersected the Valdecanas Vein deep in the central part of the vein. This hole returned low values and is within expectations for the deeper portions of the vein. This hole also helps to define the lower limitations of the Bonanza Zone in this segment of the Valdecanas Vein.

The three holes reported here were drilled as part of the ongoing 2009 drilling program which calls for a minimum of 25,000 metres of drilling on the Juanicipio property.
