MAG Silver Exploration Update in Batopilas Project


MAG Silver Corp. (TSX-V: MAG) reports that it has completed rehabilitation of the Porfirio Diaz Tunnel at its 100% owned Don Fippi Claims in the Batopilas District, Chihuahua, Mexico. The Batopilas district produced some 250,000,000 ounces of silver from shallow-level native silver-rich ores prior to 1865 and the 2.2 kilometre long Porfirio Diaz Tunnel was driven between 1882 and 1912 by the Batopilas Mining Company to provide deep level access beneath these old workings. Large amounts of native silver ores were produced through the tunnel and the company's plan was to extend crosscuts up to 3 kilometres in several directions from the tunnel to undercut numerous additional high-grade veins lying farther away. However, the Mexican Revolution intervened in 1913 and advance on the tunnel ceased abruptly, leaving more than 80% of the shallow level workings untested at depth. Numerous targets amenable to modern exploration concepts and techniques therefore remain and MAG has consolidated the district for the first time since the revolution to test them.

MAG's rehabilitated Porfirio Diaz Tunnel will allow direct underground search for new native silver oreshoots on, or adjacent to, former producing structures. Work included reconditioning over 500 metres of the tunnel, including timbering and removal of accumulated debris. Airflow has been restored and a secondary egress through the upper levels is being installed. The rehabilitated tunnel provides excellent underground drilling access as well as over 2.2 kilometres of access for testing the same sophisticated NSAMT geophysical technique MAG successfully applied at its Juanicipio Project in the Fresnillo Silver Camp of Zacatecas (See Press Release of November 21, 2003). MAG expects that the highly conductive native silver mineralization typical of Batopilas should respond well to this electrical technique and a combined NSAMT and TM orientation survey is planned for May. The last activity in the tunnel was small-scale work in the mid-1970s, which partially exploited a native silver body in the "Contrapozo Caliente" in the extreme end of the tunnel. MAG expects that the response of remnant mineralization in the Contrapozo Caliente orebody should serve as a "thumbprint" to apply throughout the district.

Surface and underground mapping and sampling are on-going and will be combined with detailed structural analysis for surface and underground drill target delineation. Permitting, road construction and site preparation are slated for 3Q-04 with drilling to begin in 4Q-04.
Qualified Person and Quality Assurance and Control

About MAG Silver Corp.
MAG Silver is focussed on exploration targets in the Mexican Silver Belt that are of interest at any conceivable silver price, in districts with known large-scale production. In addition to Batopilas, current projects include: 1) The Juanicipio and Lagartos Projects in the Fresnillo Mining District of Zacatecas...the world's premier silver producer; 2) The Guigui Project in the Santa Eulalia District, the world's largest known Carbonate Replacement Deposit (CRD); 3) The Adargas Project, one of the most gold-rich CRDs in Mexico; 4) Cinco de Mayo, a largely covered district-scale exploration play in the center of the Chihuahua CRD Belt; and 5) Sierra Ramirez, an exceptionally silver-rich CRD in eastern Durango near the famous Concepcion del Oro District.
