MAG Silver Reports Silver/Lead/Zinc Intercepts at La Esperanza Project

278 g/t (8.1 opt) Silver, 2.8% Lead and 5.8% Zinc over 2.42 Metres

Vancouver, February 22, 2012 - Canasil Resources Inc. (Canasil, TSX-V: CLZ“Canasil”) announces that  MAG Silver Corp. (TSX: MAG, NYSE-A: MVG, “MAG”) has reported significant silver/lead/zinc vein intercepts in the first three diamond drill holes of MAG’s exploration program at the La Esperanza silver project in Durango and Zacatecas States, Mexico. MAG is earning a 60% interest in the project from Canasil. The holes were drilled on one section 100 metres North West along strike from previous drilling carried out by Canasil on the main La Esperanza vein system (see attached figure).

The best results are reported in the deepest hole ES12-03, which intersected a 10.28 metre (8.22 metres true width) section of quartz vein and breccia assaying 97 grams per tonne (“g/t”) silver (2.8 ounces per ton (“opt”)), 1.1% lead and 2.3% zinc. Within this zone there is a higher grade interval reporting 278 g/t (8.1 opt) silver, 2.8% lead and 5.8% zinc over 2.42 metres. Hole ES11-02, drilled above the previous hole, intercepted 12.53 metre (10.1 metres true width) wide breccia laced with intermittent veins that carried higher grade intervals of 87 g/t (2.5 opt) silver, 0.8% lead and 2.4% zinc over 4.01 metres, including 192 g/t (5.6 opt) silver, 1.8% lead and 5.7% zinc over 1.49 metres. Near-surface hole ES11-01 hit three narrow intercepts with appreciable silver values ranging from 43 g/t (1.3 opt)  to 74 g/t (2.2 opt), lead from 0.2% to 0.6%, and zinc values from 1.0% to 1.9% over 0.85 metres to 0.86 metres (see table below).

Bahman Yamini, President and CEO of Canasil commented: “We are very pleased with MAG’s active exploration program and progress on the La Esperanza project. Following the ZTEM airborne survey and surface sampling programs, and expansion of the project area with additional 50,000 hectares of claims, these initial positive drill intercepts are very encouraging. They confirm significant silver/lead/zinc mineralization over very favourable widths on a 100 metre step out from previous drilling on the La Esperanza vein structure, which has been traced on surface for almost 5 kilometres and is open in all directions. We look forward to further results from MAG’s currently planned 4,000 metre drill program at the project.”

About La Esperanza:

The La Esperanza project covers 68,954 hectares, located within the Mexican Silver Belt in northern Zacatecas and southern Durango States. This recognized world class silver belt hosts a number of active mines such as Pan American Silver’s La Colorada and First Majestic Silver’s La Parrilla mines. The project covers multiple vein occurrences and alteration zones over a 20 kilometre strike length along a prospective SE-NW trend.

Canasil previously drilled nine diamond drill holes on the project for a total of 1,432 metres. This program outlined a mineralized panel with a strike length of over 150 metres and depth of 100 metres, which is open in all directions, with vein widths of up to 10.30 metres carrying high grade silver mineralization. Seven drill holes intersected the main Esperanza vein and a hanging wall vein over significant widths. The weighted average grade of mineralization intersected in the Esperanza vein is 330 g/t (9.62 opt) silver, 0.93% (18.60 lbs/ton) zinc and 1.57% (31.40 lbs/ton) lead over an average width of 4.21 metres. This vein includes several intercepts with very high silver grades of up to 2,144 g/t (62.53 opt) silver over 0.75 metres. 

The project is under an option agreement whereby MAG can earn 60% interest by completing CAD$ 5,000,000 in cumulative exploration expenditures ($ 912,480 completed to December 31, 2011) by September 1, 2014, and making a further CAD$ 350,000 in cash payments to Canasil by September 1, 2013.
