The World Conservation Union (IUCN), voted in its international assembly in Barcelona, October 5-14, 2008, that current mineral exploration and open pit metal mining permits be cancelled throughout Central America, and that strategic environmental assessments and other relevant instruments for environmental management be implemented and conducted in a rigorous manner, particularly in the Meso-American Biological Corridor. The measure would affect several proposed mines including the Petaquilla project in Panama and the Crucitas project in Costa Rica.
