VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 15, 2012) - MAG Silver Corp. (News - Market indicators)(NYSE Amex:MVG) ("MAG" or the "Company") announces the Company's unaudited financial results for the three months ended March 31, 2012. For complete details of the first quarter unaudited Condensed Interim Consolidated Financial Statements and related Management's Discussion and Analysis, please see the Company's filings on SEDAR (www.sedar.com) or on EDGAR (www.sec.gov). All amounts herein are reported in United States dollars unless otherwise specified.

At March 31, 2012, the Company had working capital of $20,244,060, including cash on hand of $21,776,226. The primary use of cash during the three months ended March 31, 2012 was for exploration and evaluation expenditures totaling $2,145,769 (March 31, 2011: $2,066,449), and the Company also expended on its own account and through advances to Minera Juanicipio, S.A. de C.V. ("Minera Juanicipio") $1,127,156 (March 31, 2011: $160,775) on the Juanicipio property.

The Company's net loss for the three months ended March 31, 2012 amounted to $754,371 (2011: $1,451,582). The decreased net loss compared to the first quarter of 2011 is primarily due to a deferred income tax recovery of $840,052 in the current quarter (March 31, 2011: Nil). During the quarter the Company recorded $375,856 (March 31, 2011: $501,005) of share based payment expense relating to stock options vesting to employees and consultants in the period. No stock options were granted during the period (March 31, 2011: nil). Shareholder relations expenses during the quarter amounted to $209,691 (2011: $57,733). The increase over 2011 was the result of increased local and foreign marketing activities. Interest income earned in the current quarter decreased to $71,180 (2011: $107,370), reflecting lower cash balances on hand during the current period.

OUTLOOK

Minera Juanicipio

In the three months ended March 31, 2012, Minera Juanicipio completed 8,330 metres of drilling on the property representing approximately 23% of the drilling budget proposed for the year. Currently, eight drills continue in operation on the property.

A technical study commissioned by Minera Juanicipio for the development of a 'standalone' underground silver mine on the Juanicipio property is being prepared by AMC Mining Consultants (Canada) Ltd. (the "AMC Study"). The AMC Study is in the final review stages and is expected to be released during the second quarter of 2012. The AMC Study will comply with Canadian NI 43-101 standards and will be issued as an Updated Preliminary Economic Assessment based on both Indicated and Inferred Resources. This high level economic assessment will provide an important catalyst for MAG and open a pathway for the next step in the development of the Valdecañas Vein and the Juanicipio property. It is anticipated that the 2012 Minera Juanicipio budget will be reviewed and amended to reflect the recommendations in the final AMC Study.

Cinco de Mayo

The Company originally planned to expend $3.5 million in 2012 at Cinco de Mayo (including Pozo Seco and Jose Manto) to complete 15,000 metres of drilling to delineate the mineralized corridor in the 'Bridge Zone' between the Jose Manto and Cinco Ridge. As current results continue to demonstrate strong continuity of massive sulphide mineralization in the Bridge Zone, the Company has increased its planned expenditures by a further $2 million for the 2012 year (total of $5.5 million) to accelerate the determination of width and continuity for the mineralized zone and to pin point where mineralization in the manto is thickest. This work will be utilized towards the completion of an initial silver, lead and zinc resource estimate, expected by the end of the third quarter of 2012, and the initiation of a Preliminary Economic Assessment for this property.
