MAG Silver Shareholder's Approve Continuation of Shareholder Rights Plan

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 06/23/10 -- MAG Silver Corp. (TSX: MAG) (NYSE Amex: MVG) (\"MAG\" or the \"Company\") announced today that at its annual general and special meeting (the \"Meeting\") held on June 22, 2010, MAG\'s shareholders approved the continuation of the Company\'s shareholder rights plan (the \"Rights Plan\") dated August 3, 2007 (and as amended on March 24, 2009). The vote by shareholders was 65.13% in favour of the continuation. The purpose of the Rights Plan is to encourage the fair treatment of shareholders in connection with any take-over bid for the Company. The Rights Plan provides shareholders with adequate time to properly assess a take-over bid without undue pressure. It is also intended to provide the board of directors with more time to fully consider an unsolicited take-over bid and, if considered appropriate, to identify, develop and negotiate other alternatives to maximize shareholder value. A copy of the Rights Plan is available under MAG's profile on SEDAR at www.sedar.com and on EDGAR at www.sec.gov.

At the Meeting, the number of directors serving on the board was increased from seven to eight, with all previous seven directors being re-elected and the election of Frank Hallam. Mr. Hallam has been the Company\'s Chief Financial Officer since its qualifying transaction in 2003 and has in-depth knowledge of the Company and its operations. Mr. Hallam is a director and co-founder of Platinum Group Metals Ltd., West Kirkland Mining Inc. and Nextraction Energy Corp. He was also a co-founder and director of West Timmins Mining Inc. and now serves as a director of Lake Shore Gold Corp. after its business combination with West Timmins in 2009. With his election to the board, Mr. Hallam will not be continuing as the Company\'s CFO.

The board of directors has appointed Mr. Larry Taddei as its new CFO. Mr. Taddei obtained his Chartered Accountant designation in 1990 and has held senior accounting and finance roles in the natural resource sector for the past 20 years. Most recently, he was the CFO of West Timmins Mining Inc. up until its business combination with Lake Shore Gold Corp., a transaction valued at over $420 million. Previous to this, he held the position of CFO with a Vancouver-based precious metals producer with operations in South America, where he was instrumental in the completion of both debt and equity financings and oversaw the transition of the Company from an explorer to a producer.

Also at the Meeting, Deloitte & Touche LLP was re-appointed as the Company\'s auditor and an amendment to the Company\'s stock option plan was approved.
