"MAG SILVER ANNOUNCES DRILL PROGRAM TO TEST SILVER INTERSECTIONS AT GUIGUI PROPERTY"


Vancouver, B.C... MAG Silver Corporation (TSXV: MAG) announces a diamond drill rig has been mobilized to their 4,553 ha Guigui property in the Santa Eulalia Mining District in Chihuahua State in north-central Mexico. The 2005 drill program will consist of 3 to 4 holes totalling approximately 2,000 metres designed to follow up on the intersections of extensive alteration, structure and mineralization encountered in MAG's 2004 program (c.f. 131 ppm Ag over 8.30m or 4.2 opt Ag over 27 feet) (See Press Release of April 30, 2004). The drill area is located about 1.2km south of Grupo Mexico's recently reopened San Antonio Mine and about 650m south of their nearest underground infrastructure. The target area lies within the San Antonio Graben (SAG), a prominent N-S structural feature that hosts and controls the mineralization at the San Antonio Mine. Drilling of two holes into the West Fault of the SAG last year by MAG Silver confirmed that San Antonio style mineralization and alteration extends into the Guigui property. Grupo Mexico is presently developing a new zone discovered in the footwall of this fault about 850m along-structure from MAG's target area.


MAG's 2004 intercepts are interpreted to be a high-level halo reflecting significant mineralization at depth, so the 2005 drilling will be focused along strike and to depth below these intersections. Mineralization in the San Antonio Mine is more laterally extensive when intersected below 1,250 metres elevation, so MAG intends to drill to and below this level in their current program. One hole is also planned to test the East Fault of the SAG because mineralization also occurs in this structure in the San Antonio Mine, and there are several old mines and prospects along it within the Guigui target area. Road and drill pad building have already been completed, and drilling should commence over the weekend.


The Guigui land package and exploration program in the Santa Eulalia Mining District are in keeping with MAG's commitment to district-scale exploration in districts with large-scale historic mining of high-grade silver ores. Santa Eulalia is the largest Carbonate Replacement Deposit in the world (50 million tonnes at 350 g/t Ag (11.3 opt), 8.2% lead and 7.8 % zinc). Historical silver production is over 500 million ounces in tandem with roughly 4 million tonnes each of lead and zinc. The San Antonio Mine in the district's East Camp accounts for almost 40% of the total production and has recently been reactivated. The West Camp of the district encompasses the largest manto and chimney system known, and MAG controls a large and highly prospective land package immediately to the south, where the intrusive-related source of this mineralization is believed to lie. MAG Silver continues to develop drill targets in this area.

MAG SILVER ACCELERATES PURCHASE OF

THE DON FIPPI AND GUIGUI PROPERTIES



Vancouver, B.C... MAG Silver Corporation (TSXV:MAG; OTCBB:MSLRF) announces the accelerated buyout of the Don Fippi (Batopilas) and Guigui (Santa Eulalia) Properties both located in Chihuahua State, Mexico. With this purchase MAG Silver eliminates exposure to further cash payments of US$900,000, work expenditure commitments of US$5.25M, and issues 1,200,000 shares less than that anticipated under the original option agreement. The properties will remain subject to royalties and other terms of the original option agreement.


Under the terms of the buyout agreement MAG will issue the underlying agreement holders a total of 1,500,000 common shares of MAG Silver Corporation disbursed at 750,000 shares per property. This purchase gives MAG Silver Corporation an undivided 100% interest in the properties. The terms of the deal are subject to approval from the TSXV.


The MAG Silver management team has determined that the properties are integral to MAG's commitment to district scale exploration and owning them outright will be a strong benefit to the Company's future.


MAG originally optioned the two properties in 2003 and has conducted exploration work on both properties from 2003 through 2005. MAG has recently announced the commencement of a diamond drill program at Guigui (see MAG news release of June 2, 2005) to follow up the silver and base metal intersections from last years phase one drill program.


The underlying property/agreement holders are owners and partners of Minera IMDEX/Cascabel, the largest mineral exploration consulting group in Mexico. IMDEX/Cascabel will continue to provide geotechnical consulting services to MAG Silver as required. Dr. Peter Megaw, president of IMDEX, says "We are pleased that MAG has chosen to exercise these options early; reflecting MAG's confidence in the importance of these projects. This makes us major shareholders in MAG and we look forward to focusing our efforts on adding value to MAG through well integrated exploration of all MAG's holdings."


Dan MacInnis, President and CEO of MAG comments "MAG's exploration programs have validated IMDEX/Cascabel's original exploration concepts that were in place at the time MAG became involved in these projects. With this outright purchase we now control these properties and the districts to the long term benefit of MAG Silver".

MAG's property inventory includes the Don Fippi (Batopilas) Property, the Guigui Property and the Juanicipio/Lagartos properties in the Fresnillo trend. The scale of these projects confirms MAG as the most active district scale explorer in Mexico. We now have four major silver district programs where MAG Silver controls the entire district and/or are the largest landholder.
