Protests in Mendoza, Argentina, are escalating against the San Jorge copper mining project, approved in December 2025 by the provincial parliament. The project, involving a joint venture between Switzerland's Zonda Metals and Argentina's Grupo Alberdi, aims to extract copper using potentially harmful chemicals.

Local activists, led by lawyer Alejandra Pariani, argue that mining threatens vital water resources in a region reliant on Andean glacier meltwater. Concerns also arise from recent legal changes weakening environmental protections, particularly the 7722 law which previously restricted toxic substances in mining. Proponents claim the project will bring economic benefits, but dissenters highlight the environmental risks and potential harm to local communities.
