Canasil Resources Inc. announces that Pan American Silver Corp. has elected to terminate the option agreement on Canasil’s Carina silver-gold project in Durango State, Mexico. At the time of entering into the agreement, Pan American was required to assign the agreement to the La Preciosa joint venture between Pan American and Orko Silver Corp. As previously announced by Orko on April 5, 2012, Pan American has relinquished its right to earn a 55% interest in the La Preciosa project and the Carina option will not be continued by the La Preciosa joint venture company. As a result Canasil now retains 100% interest in the Carina project.
