Tailings Dam Management

What are tailings?

Tailings are the materials left over following the processing of mined ore that separates the valuable metals or minerals from the host rock. Tailings are not the same as waste rock, the latter being soil or rock or other material that covers or surrounds an orebody and that is displaced during mining but is not processed.

What is a tailings storage facility?

Tailings storage facilities (TSF) play a major role in many mining operations around the world. A TSF is a highly engineered structure which consists of one or more tailings dams, with embankments designed to permanently store the tailings in a safe, sustainable, and environmentally responsible manner.  Every individual dam is unique and is designed, built and operated to specifications that are tailored to the physical nature of the tailings material itself, and a number of other factors.  Our tailings facilities are managed taking into account a combination of site-specific conditions, applicable laws and regulations, and annual dam safety inspections and reviews, as required. Please refer to the following summary for more details regarding Great Panther’s tailings storage facilities in Mexico, Peru and Brazil.
