Mag Silver to expand Jose Manto at Cinco De Mayo

MAG Silver Corp., a mining company focused on district scale projects located within the Mexican Silver Belt, provides assay results for 10 recent diamond drill holes from its fully owned Cinco de Mayo property in northern Chihuahua State, Mexico.

Cinco de Mayo is a 15,000 hectare property straddling the same regionally-mappable structure that contains the largest Carbonate Replacement Deposits (CRDs) in Chihuahua.

The company is focusing its ongoing drill program on expanding the “Jose Manto” discovered with Hole 07-20 in late 2007 and subsequently intersected in Holes 22 through 28.

These holes extend the Jose Manto to an area of at least 300 metres by 400 metres and mineralisation in outlying Hole 08-32 may extend this an additional 600 metres to the southeast.

The best new intercept is Hole 08-39, which cut 3.46 metres of 612 grams per tonne (g/t) silver (17.8 ounces per ton (opt), 11.59% lead and 13.20% zinc: including 2.36 metres of 772 g/t silver (22.5 opt), 13.42% lead and 16.39% zinc.

All intercepts lie at about 400 to 550 metres vertical depth and appear to define a coherent massive sulphide sheet (“manto”) developed within a low-angle fault cutting strongly folded limestone.

Most of the holes have cut multiple, closely spaced, high grade massive sulphide intersections within limestones of the Finlay Formation, with the thickest and most persistent occurring near its upper and lower contacts.

Textural evidence for multiple mineralisation stages indicative of a large system is strong.
