VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 4, 2012) - Canasil Resources Inc. (News - Market indicators)(FRANKFURT:3CC) ("Canasil") announces that MAG Silver Corp. (TSX:MAG)(NYSE MKT:MVG) ("MAG") has mobilized crews to prepare for the start of the Phase 2 drill program in early October 2012 at Canasil's La Esperanza silver-zinc-lead project in Durango and Zacatecas States, Mexico. Plans include up to 3,500 metres of Diamond drilling to test three silver-lead-zinc veins in the northwest of the project area. This drill program will be part of the CAD$1,500,000 exploration expenditures required between September 2012 and September 2013 under the option agreement for MAG to earn a 60% interest in the La Esperanza project.

Surface sampling by MAG at these veins has returned consistent silver values. Samples returning higher than 100 g/t silver are listed in the table below, with a significant number of samples returning over 300 g/t silver:

Quality Assurance and Control: MAG Silver has in place a quality control program to ensure best practices in sampling and analysis. Samples were collected by employees of consulting firm Minera Cascabel S.A. de C.V. on behalf of MAG Silver Corp. One blank and standard sample are each inserted into each batch of 20 total samples. The samples are then shipped directly in security sealed bags to ALS-Chemex Laboratories preparation facilities in Zacatecas City (Certification ISO 9001). Sample pulps are shipped from there to ALS-Chemex Laboratories in North Vancouver, Canada for analysis. Silver, zinc, copper and lead values are determined by Atomic Absorption Spectrometry and where in excess of 100 ppm, 1%, 1% and 1% respectively are also repeated by fire assay. Gold assays were by standard fire assay-ICP finish and those in excess of 3.00 g/t are re-analyzed by fire assay with gravimetric finish.

About La Esperanza:

The La Esperanza project covers 68,954 hectares, located in 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 where the results of an airborne geophysical survey conducted by MAG indicate potential for hosting a very large mineralized system.

Drilling conducted by Canasil and MAG on the La Esperanza vein has confirmed a high-grade silver-zinc-lead mineralized panel along a strike distance of over 250 metres and to a depth of 300 metres, which is open in all directions, with mineralized vein intercepts of up to 10.30 metres. Recent drilling by MAG intersected a 10.15 metre intercept carrying 98 g/t (2.86 opt) silver, 2.42% zinc and 1.16% lead, including 2.42 metres with 278 g/t (8.10 opt) silver, 5.82% zinc and 2.84% lead. The La Esperanza 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 a 60% interest by completing CAD$5,000,000 in cumulative exploration expenditures by September 1, 2014, (CAD$1,624,393 completed to June 30, 2012) and making a further CAD$200,000 cash payment to Canasil by September 1, 2013.
