Item 4                                Summary of Material Change

Vancouver, B.C...MAG Silver Corp. (TSX:MAG, AMEX:MVG) (“MAG”) announces assay results from an ongoing drill program on MAG’s 100% owned Cinco de Mayo property in northern Chihuahua State, Mexico. This drill program is expanding the  “Jose Manto” discovered in Hole 07-20 which intersected 6.8 metres (estimated true thickness) of galena and sphalerite-rich massive sulphides grading 254 g/t (7.4 opt) silver, 6.4% lead and 7.0% zinc.  See press release dated February 7, 2008 for details.

Recent Holes 08-22 through 08-28 have now cut the Jose Manto over an area of approximately 250 by 250 metres.  Assays are presented below.  Highlights include Hole 08-28 reporting 4.00 metres of 192 g/t silver (5.6 opt), 4.22% lead and 11.65% zinc and Hole 08-22 which returned 2.78 metres of 209 g/t (6.1 opt) silver, 6.15% lead and 6.55% zinc. Intercepts are believed to be true widths.  Mineralization is open in all directions and two rigs are currently drilling systematic 25 to 50 metre offsets of these holes to define the axis of maximum thickness of the manto and trace it towards its source. Drill plan is attached and cross-sections can be found at www.magsilver.com.
