Goldcorp's Chilean project delayed.

CONSULTATION CONCERNS

The permit was ruled invalid on the grounds that Chile's environmental permitting authority had not adequately consulted with the indigenous people affected by the project.

The Huasco Altinos indigenous group that has opposed the El Morro project has argued the mine would harm livestock-rearing, restrict scarce water supply and infringe on sacred and ancestral lands.

Consuelo Labra, a lawyer for Huasco Altinos, cheered the court's ruling.

"This validates the rights of indigenous people. It's a very positive decision ... against a huge project," she said, noting that the country lacks a standardized consultation process.
