A critical part of Great Panther’s commitment to sustainable mining is managing tailings and other waste in a safe and environmentally responsible manner, in line with local regulations and evolving industry standards.
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.
We construct tailings storage facilities – highly engineered structures that consist of one or more tailings dams – with embankments designed to permanently store the tailings in a safe, sustainable, and environmentally responsible manner. We currently have eight TSFs across our locations, three of them inactive.
Each dam is designed, built and operated to specifications that are customized to the physical nature of the tailings material, site-specific conditions, applicable laws and regulations. Our operating and closed sites each meet or exceed regulatory requirements, and we are continually improving the management of our facilities by developing and incorporating best practices. A number of proactive safety measures are in place that include regular inspections by local officials and government authorities as well as our staff. We also arrange regular independent design and operational reviews by suitably qualified experts who are not involved in the design or construction of the facility.
