On November 16 and 18, 2015, E-Tech International presented technical models of the impacts of a tailings dam failure downstream of the Chinese Ecuacorriente Mirador Mine in the Cordillera del Condor of Ecuador.  A tailings failure would impact the Rio Santiago that enters Peru and subsequently the Maranon River, main tributary in the region to the Amazon.    The studies by Dr. Steven Emerman were a component of seminars at the Universidad Tecnica de Loja in the Cordillera del Condor as well as the Escuela Politecnica Nacional in Quito.    Recent tailings and other mine waste failures at the Polley Mine in British Columbia, Cananea Sonora, Silverton Colorado and Mina Gerais, Brasil have made such models as instruments to prevent disaster very important.
