MAG SILVER SHAREHOLDER’S APPROVE CONTINUATION OF SHAREHOLDER RIGHTS PLAN

Vancouver, BC -- MAG Silver Corp. (TSX:MAG; NYSE-A: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 ident ify, 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.

Neither the Toronto Stock Exchange nor the American Stock Exchange has reviewed or accepted responsibility for the accuracy or adequacy of this news release, which has been prepared by management.

This release includes certain statements that may be deemed to be “forward-looking statements” within the meaning of the US Private Securities Litigation Reform Act of 1995. All statements in this release, other than statements of historical facts are forward looking statements including statements, including statements that address future mineral production, reserve potential, exploration drilling, exploitation activities and events or developments. Forward-looking statements are often, but not always, identified by the use of words such as "seek", "anticipate", "plan", "continue", "estimate", "expect", "may", "will", "project", "predict", "potential", "targeting", "intend", "could", "might", "should", "believe" and similar express ions. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements. Although MAG believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include, but are not limited to, changes in commodities prices, changes in mineral production performance, exploitation and exploration successes, continued availability of capital and financing, and general economic, market or business conditions, political risk, currency risk and capital cost inflation. In addition, forward-looking statements are subject to various risks, including that data is in complete and considerable additional work will be required to complete further evaluation, including but not limited to drilling, engineering and socio-economic studies and investment. The reader is referred to the Company’s filings with the SEC and Canadian securities regulators for disclosure regarding these and other risk factors. There is no certainty that any forward looking statement will come to pass and investors should not place undue reliance upon forward-looking statements.

Cautionary Note to U.S. Investors: The U.S. Securities and Exchange Commission permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We use certain terms in this press release, such as “Inferred resources,” that the SEC guidelines prohibit U.S. registered companies from including in their filings with the SEC.

Please Note: Investors are urged to consider closely the disclosures in MAG's annual and quarterly reports and other public filings, accessible through the Internet at www.sedar.com and www.sec.gov/edgar/searchedgar/companysearch.html.

ARTICLE 5
ELIGIBILITY, GRANT AND TERMS OF OPTIONS

5.1

Eligible Persons

Subject to the provisions of the Plan, Options may only be granted to Eligible Persons.

5.2

General

Subject to the other provisions of this Article 5, the Committee shall determine the number of Shares subject to each Option, the Option Price, the expiry date, the extent to which each Option is exercisable from time to time during the term of the Option and other terms and conditions relating to each such Option; provided, however, that if no specific determination is made by the Committee with respect to the expiry date, the period during which an Option shall be exercisable shall be five years from the date the Option is granted to the Option Holder. Without limiting the generality of the foregoing, Options may be granted by the Committee from time to time in accordance with this Article 5 during a Blackout Period, provided that in no event shall such Options be exercisable until after the Option Price applicable to such Options is fixed by the Committee in accordance with Section 5.3.

5.3

Option Price

The Option Price shall in no circumstances be lower than the Market Price of the Shares at the Grant Date.  If the Committee grants Options to an Option Holder during a Blackout Period applicable to such Option Holder, the Option Price fixed by the Committee on Shares which are the subject of such Options shall be equal to the greater of (i) the Market Price of the Shares at the date of the grant of the Options, and (ii) the Post-Blackout Period Price following the end of such Blackout Period.

- 10 -

5.4

Term of Option

Subject only to Section 5.5, in no event may the term of an Option exceed five years from the Grant Date.

5.5

Extension of Term for Options Expiring During Blackout Periods

Notwithstanding anything else contained herein, if the term of an Option held by an Option Holder expires during or within 10 Business Days of the expiration of an Blackout Period applicable to such Option Holder, then the term of such Option or the unexercised portion thereof, as applicable, shall be extended to the close of business on the tenth Business Day following the expiration of the Blackout Period.

5.6

Exercise Period

Options will vest and be exercisable in the manner determined by the Committee and specified in the applicable Option Document. Once an Option becomes exercisable, it remains exercisable until expiration or termination of the Option, unless otherwise specified by the Committee in connection with the grant of such Option or at the time of an accelerated vesting.  Each Option may be exercised at any time or from time to time, in whole or in part, for up to the total number of Shares with respect to which it is then exercisable.  Notwithstanding anything else contained herein, Options may not be exercised during a Blackout Period unless the Committee determines otherwise.

The Committee may elect, at any time, to accelerate the vesting schedule of one or more Options and such acceleration will not be considered an amendment to the Option in question requiring the consent of the Option Holder under Section 10.2 of this Plan.  

5.7

No Repricing

In no event may outstanding Options granted under this Plan be repriced.  

5.8

Additional Limits

Notwithstanding any other provision of this Plan or any agreement relating to Options, no Options shall be granted under this Plan if, together with any other Share Compensation Arrangement established or maintained by the Company, such grant of Options could result, at any time, in the aggregate number of Shares (i) issued to insiders, within any one-year period and (ii) issuable to insiders, at any time, exceeding 10% of the issued and outstanding Shares.

5.9

Option Documents

All grants of Options will be evidenced by Option Documents.  Such Option Documents will be subject to the applicable provisions of this Plan and will contain such provisions as are required by this Plan and any other provisions that the Committee may direct.  By accepting an Option granted hereunder, the Option Holder has expressly agreed with the Company to be bound by the terms of this Plan.  In the event of conflict between the terms of an Option Document and the terms of this Plan, the terms of this Plan shall prevail and the Option Document shall be deemed to have been amended accordingly.

- 11 -

5.10

ISOs

ISOs shall be granted only to an individual who is an Employee of the Company or a Subsidiary or related company and shall be subject to the following special limitations required by Section 422 of the Code, and any contrary provisions of this Plan shall be disregarded:

(a)

Limitation on Amount of Grants.  As to all ISOs granted under the terms of this Plan, to the extent that the aggregate fair market value of the Shares (determined at the time the ISO is granted) with respect to which ISOs are exercisable for the first time by the Option Holder during any calendar year (under this Plan and all other ISO plans of the Company, a related corporation or a predecessor corporation) exceeds US$100,000, such options shall be treated as NSOs.  The previous sentence shall not apply if the Internal Revenue Service issues a public rule, issues a private ruling to the Company, any Option Holder or any legatee, personal representative or distributee of an Option Holder or issues regulations changing or eliminating such annual limit.  No such limitation shall apply to NSOs.

(b)

Grants to Ten Percent Shareholders.  ISOs may be granted to a person owning more than 10% of the total combined voting power of all classes of shares of the Company and any Parent or Subsidiary only if (i) the exercise price is at least 110% of the fair market value (determined in accordance with section 422 of the Code) of the stock at the time of grant, and (ii) the option is not exercisable after the expiration of five years from the date of grant.

(c)

Notice of Disposition.  The Committee may require an Option Holder to give the Company prompt notice of any disposition of Shares acquired by exercise of an ISO prior to the expiration of two years after the date of the grant of the option and one year from the date of exercise.

(d)

Shareholder Approval.  No Options granted under this Plan will be considered ISOs unless this Plan has been approved by the shareholders of the Company within twelve months before or after the date such Plan has been adopted by the Committee.

ARTICLE 6
TRANSFERABILITY

6.1

Transferability

An Option is personal to the Option Holder and is non-assignable and non-transferable.  No Option granted hereunder shall be pledged, hypothecated, charged, transferred, assigned or otherwise encumbered or disposed of by the Option Holder, whether voluntarily or by operation of law, otherwise than by testate succession, will or the laws of descent and distribution, and any attempt to do so will cause such Option to terminate and be null and void.  During the lifetime of the Option Holder, an Option shall be exercisable only by the Option Holder and, upon the death of an Option Holder, the person to whom the rights shall have passed by testate succession or by the laws of descent and distribution may exercise any Option in accordance with the provisions of Section 7.2(b) or 7.4(b), as applicable.  

- 12 -

ARTICLE 7
TERMINATION OF EMPLOYMENT OR SERVICES; DEATH AND DISABILITY

7.1

General

An Option, and all rights to purchase Shares pursuant thereto, granted to an Eligible Person shall expire and terminate immediately upon the Option Holder ceasing to be an Eligible Person, other than in the circumstances referred to in Sections 7.2, 7.3 and 7.4.

7.2

Termination of Employment or Term of Office

If, before the expiry of an Option in accordance with its terms, the employment or term of office of an Option Holder that is an Employee or Executive terminates for any reason whatsoever other than termination by the Company or the Subsidiary for cause (for this purpose, as determined by the Committee in its discretion), but including (i) the termination by the Company or Subsidiary without cause; or (ii) the voluntary resignation by the Option Holder; or (iii) the termination of employment or term of office by reason of the death or Disability of the Option Holder, the Options held by such former Employee or Executive that are exercisable at the Termination Date continue to be exercisable by the Option Holder as follows:
