The independent mineral resource estimate for Nuevo Milenio continues to be advanced. Challenges encountered in providing data to the consultant in a timely manner have impacted progress on the mineral resource estimate. Given the large amount of data involved including over 32,000 metres of drilling, a significant volume of surface samples, trench samples, underground channel samples as well as properly identified location coordinates for all but the drilling data combined with reviews and fact checks were significantly more time consuming than anticipated. The Company anticipates the release of the mineral resource by May month end 2012.

Canasil Resources Inc. announces that MAG Silver Corp. has completed 8 additional drill holes on the Esperanza Vein at Canasil’s La Esperanza silver-zinc-lead project in Durango and Zacatecas States, Mexico. These holes were blind step-outs on projection of the vein located 400 metres northwest, 350 metres southeast and 1,000 metres southeast of the previously drilled high-grade ore shoot, which returned very encouraging silver, zinc and lead intercepts in MAG’s initial 3 drill holes, previously reported on February 22, 2012, as well as in previous drilling by Canasil. The latest holes did not intercept the vein, most probably due to apparent post-mineral faulting that has displaced the vein, which will be investigated in future exploration and drilling. MAG interprets the large aeromagnetic anomaly observed in the Esperanza vein zone, measuring approximately 5 kilometres by 3 kilometres, as a possible signature of a significant mineralized system which will continue to be explored.
