This program is targeted for completion by the end of the year and a second drill rig has been moved onto the site with two more drill holes currently underway.

We are pleased to see Penoles moving aggressively ahead with the drill program" said MAG Silver President, Dan MacInnis.


Industrias Penoles is the largest silver producer in the world and owns and operates the world's largest silver Mine at Fresnillo. The Juanicipio Joint Venture property is located adjacent to the Fresnillo Mine and boarders Penoles newest gold silver discovery at El Saucito. The El Saucito vein runs for more than 1.4 kilometres, averages 2 metres in width and hosts 11 g/t Au equivalent. Drilling at this discovery continues to extend the deposit in an east west direction.

  

The principal features of the agreement are:
