More Silver/Lead/Zinc Sulphides In Bridge Zone Intersected

VANCOUVER, BC - MAG Silver Corp. reported 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. 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.

The best hole is CM12-390 which cut 274 grams per tonne ("g/t") (8.0 ounces per ton ("opt")) 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). 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.

The remaining holes have all cut massive sulphides ranging from 1.50 to 5.25 metres in thickness. As is typical of the Jose Manto, the percentage of massive sulphide ranges from roughly 50% to nearly 100% of the composite manto thickness. Sulphides are dominated by pyrite, argentiferous galena and dark coloured sphalerite. Barite is locally abundant.

This series of holes is the first full cross-section across the "Bridge Zone" between the Jose Manto and Cinco Ridge and shows manto width, thickness and composition comparable to the well constrained body of the Jose Manto. The similarity of manto dimensions, composition and textures strongly indicates that mineralization maintains these dimensions throughout the Bridge Zone and into the Jose Manto, which if confirmed will reveal continuous manto-style mineralization at least 4,000 metres long that plunges irregularly downwards to the northwest from 200 to 450 metres depth.

Drilling of progressive fences of holes along the Bridge Zone is underway with two drill rigs. Currently, the fence across Hole CM11-377 is in progress. (Hole 377 reported 5.25m grading 280 g/t (8.2 opt) silver with 6.1% lead and 6.2% zinc). A third rig is dedicated to exploration for the source of the manto.
