Material Changes and Events
- Regulatory Action: The Federal Attorney General of Mexico (PGR) executed a search warrant at the Buenavista del Cobre mine on August 29, 2014, concluding on August 30. Certain offices were temporarily sealed but reopened; mining operations were not affected.
- Incident Background: The search stems from a criminal complaint by the Federal Attorney's Office for the Protection of the Environment (PROFEPA) regarding a copper sulfate acid spill into the Bacanuchi river on August 6, 2014.
- Clarification of Reporting Timeline: The Company disputes public claims that it notified authorities six days after the spill. It asserts immediate notification occurred on August 7, 2014, via telephone and email, followed by formal written notice on August 12, 2014.
- Cause of Accident: Initial assessments pointed to excess rainfall raising solution levels. Current information indicates a construction defect in the seal of a pipe in the Tinajas 1 system (part of a new plant construction subcontracted to TECOVIFESA) was a relevant cause, with rainfall acting as a contributing factor.
