represents an

important step in unlocking value for Orex shareholders. By receiving equity in Silver Viper, Orex

maintains meaningful exposure to the continued advancement and exploration potential of the

presence in Mexico while providing our shareholders participation in the broader growth of Silver

Viper's Mexican asset portfolio."
