At approximately 12:28 p.m. local time on January 25, 2019, tailings dam B-I at Vale S.A.’s Córrego do Feijão Iron Ore Mine (“Dam I”), located 9 kilometers (km) north-east of Brumadinho, in the state of Minas Gerais, Brazil, suffered a sudden failure, resulting in a catastrophic mudflow that traveled rapidly downstream.

This technical memorandum was prepared in response to Groundwater Work Group Action Item WR-12 “Pull well records and other information for QV and model the impacts” to provide information to address Draft Environmental Impact Statement (DEIS) comments about potential impacts to Queen Valley, Arizona water supplies from proposed Resolution Copper mining activities.

This paper discusses reasons including seepage, foundation failure, overtopping, and earthquake for tailings dam failures and explores failure mechanisms by referring to the available literature.

This letter is in response to questions posed by BGC Engineering "Assessment of Surface Faulting Investigations at the Skunk Camp TSF Location".
