MAG Silver Options Salamandra Project From Canasil

VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 05/28/13 -- MAG Silver Corp. (TSX: MAG) (NYSE MKT: MVG) ("MAG" or the "Company") announces that the company has entered into an option agreement with Canasil Resources Inc. ("Canasil") whereby the Company can earn up to a 70% interest in Canasil's 14,719 hectare Salamandra property located in Durango State, Mexico. The project is strategically located along the overlap between the "Mexican Carbonate Replacement Belt" and the "Fresnillo Silver Trend" often referred to as Mexico's Premier Silver-Gold district. Salamandra lies on trend with a number of important operating mines and recent new discoveries. Salamandra is only 80 kilometres northwest of the San Martin-Sabinas Mining District, the largest underground silver-copper-zinc deposit in Mexico (owned by Grupo Mexico and Penoles) and Salamandra boasts remarkably similar geology although exposed at a slightly higher stratigraphic level.

"Salamandra is exceptionally well located geologically and shows more of the hallmark features of a major CRD system than our Cinco de Mayo property did when we started there," said Dan MacInnis, President and CEO of MAG Silver. "We've had our eyes on Salamandra for nearly four years and are pleased that Canasil has finally given us the opportunity to bring our expertise on CRD systems to bear on this exciting project. Building on Canasil's technical foundation should allow us to bring Salamandra to drill-readiness quickly."

To complete the initial earn-in of a 55% interest in the Salamandra project, MAG must complete CAD$5,500,000 in exploration expenditures on the property and CAD$750,000 in cash payments to Canasil over a period of four years. An initial payment of CAD$150,000 was paid upon signature of the binding letter agreement and a first year work expenditure of CAD$1,000,000, including a minimum of 3,000 metres of drilling, is a firm commitment. All other work commitments escalate annually and are optional as are the cash payments. At MAG's option it can earn an initial 55% interest and form a 55 / 45 joint venture with Canasil, or earn a cumulative interest of 70% (an additional 15%) by producing either a feasibility study or spending an additional CAD$20M over another four year period. At that point a 70 / 30 joint venture would be formed, subject to normal dilution provisions whereby a subsequent 15% interest by either party will convert to a 2.5% net smelter royalty.

About Salamandra:

The Salamandra project covers 14,719 hectares (36,371.44 acres) and is located 35 kilometres northeast of the city of Durango in the El Guadiana valley in Durango State. Access is excellent from the city of Durango via paved and gravel roads. Exploration results to date at the Salamandra project indicate the potential for a large intrusive-related, carbonate-hosted massive sulphide skarn/manto replacement system (CRD). The mineralized system is centered on a domal structure related to an intrusive complex that occupies the center of the property. Widespread silver-copper-antimony-arsenic surface anomalies with peripheral lead and zinc anomalies are found over a very large area. Extensive skarn and hornfels, intrusive and mineralized breccia dikes, and well mineralized fracture/veins represent a few of the hallmark CRD features that are present. Prior drilling cut high-grade zinc and silver mineralization within hornfels which is believed to overlie the same thick limestone host rock section that hosts the nearby San Martin-Sabinas, La Parilla and La Colorada CRD mines.

Canasil previously drilled 12 diamond drill holes in a limited part of the property for a total of 3,595 metres.
