The Global Action on Tailings is a GMPA initiative, to engage and connect technical experts to advance discussions and solutions relating to tailings management, tailing reprocessing, repurposing and ultimately driving toward tailings elimination.
The increasing rate of tailings dam failures is directly related to the increasing number of tailings impoundment areas larger than 5 million cubic meter capacity. Losses of human life, as well economic and ecological impacts, either permanent or non-recoverable, are often immense. The average cost of these catastrophic tailings dam failures is $543 million. Mining companies cannot afford, nor financially secure the costs of catastrophic failures. In addition, the reputational impact of a dam failure is devastating.
To compound this, climate change and ageing mines have made the problem more pressing, with precipitation levels increasing in many parts of the world, and older dams with designed with out-dated specifications. Today, tailings management is the most pressing issue facing our sector.
Collectively the GPMA membership has tens of thousands of technical experts around the world with experience in all aspects of mine waste and tailings.
An international Taskforce of experts representing each GMPA association is working together to build awareness and knowledge of tailings management through information on design, operation, risk management and improvement opportunities, and education and professional development activities to enhance competencies in tailings management.
In addition, each GMPA organization has established specialist tailings committees providing guidance on conferences, online technical education, publications, as well as strategic input into industry reviews and consultations.
