MAG Silver Intercepts More Silver / Lead / Zinc Sulphides in "Bridge Zone" at Cinco de Mayo

MAG Silver Corp.

announces significant massive sulphide intercepts in drilling in the "Bridge Zone" along the Jose Manto-Cinco Ridge corridor within its 100% owned Cinco de Mayo property in northern Chihuahua State, Mexico. Ten holes were drilled on a section to test the up- and down-dip continuity of hole CM11-380, the best of seven massive sulphide manto intercepts drilled late in 2011 (see press release dated November 28, 2011). The results clearly demonstrate the lateral and vertical continuity of the mineralization. The current holes were drilled on 50 metre centres and eight of the ten holes (including hole CM11-380 which cut 386 g/t silver with 14.0% zinc and 8.2% lead over 3.98 metres) intercepted massive sulphides (assays pending on two holes). The combined drilling shows continuous mineralization over a 400 metre dip length, with mineralization remaining open down dip and along strike. All reported intercepts appear to be near true widths (See Diagram One and Two). The best hole is CM12-390 which cut 274 grams per tonne ("g/t") (8.0 ounces per ton) silver with 5.5% lead and 17.2% zinc over 8.08 metres; including: 1.63 metres that grades 778 g/t (22.7 opt) (see Table 1). This intercept is actually the sulphide portion of a 14.1 metre thick manto zone where the top 6.0 metres is partially to completely oxidized and leached sulphide.
