MAG Silver and Penoles Initiate 2006 Drill Program at Juanicipio

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 15, 2006) - MAG Silver Corp. (TSX VENTURE:MAG) and Industrias Penoles S.A. de C.V. today announced that a permit has been received that will allow the 2006 diamond drill program to commence on the Juanicipio Joint Venture in Zacatecas State, Mexico. Initial road construction is expected to be completed shortly and for logistical reasons and ease of access start up drilling will probe an area 1,700 metres west along the projected strike of the new high grade Valdecanas silver / gold vein discovery reported in a press release dated January 23, 2006. The discovery (Hole 16) returned over 6.35 metres (20.8 feet) of 1,798 grams per tonne Silver (57.8 ounces), 2.91 grams per tonne Gold, 3.43% Lead and 5.51% Zinc.

"The new silver / gold vein discoveries at Juanicipio and El Saucito have expanded the Fresnillo Silver District significantly to the west," stated David Giles, Exploration Manager for Penoles in Mexico. "The 2006 program at Juanicipio will be focused on defining the extent of the high grade vein intercept in hole 16 and expanding the search for others on the Juanicipio property."

The Penoles-MAG Joint Venture on the Juanicipio Property lies 5 kilometres west from the principal production head-frame of the Fresnillo Mine, and 2.3 kilometres from its westernmost underground workings. The "El Saucito Vein", currently subject to extensive surface drilling and underground development from a new shaft, lies 1.3 kilometres from the eastern boundary of Juanicipio. Prior to the latest discovery MAG Silver had reported the discovery of several vein intercepts on the property including the Juanicipio Vein. In total these significant new mineral discoveries enlarge the mineral endowment of the Fresnillo mine district and highlight the significant potential for new and similar discoveries "under cover" in and along the Fresnillo trend.
