Mines are loved by proponents and governments, seen as beacons of prosperity and often fast-tracked through the very assessment, regulation and monitoring procedures that would have improved them. But eventually all mines become orphans, because while humanity is great at digging holes, we have a growing legacy of abandoned, troublesome and downright dangerous sites.
This page includes a report for the UNEP on tailings dams disasters and articles/reports from MPI’s long-term focus on mining legacies. An approach used to more honestly evaluate old and new mines.
Mine Tailings Storage: Safety Is No Accident
Editors: Roche, C., Thygesen, K., Baker, E.
Preface: Mining companies, communities and governments recognize that mine waste, contaminated water and land pollution damage lives and livelihoods but also threaten the development of the mining sector. For this reason, they are committed to
Despite many good intentions and investments in improved practices, large storage facilities, built to contain mine tailings can leak or collapse. These incidents are even more probable due to climate change effects. When they occur, they can destroy entire communities and livelihoods and remain the biggest environmental disaster threat related to mining.
The mining industry has acknowledged that preventing catastrophic tailings dam incidents with zero fatalities and environmental protection is fundamental and achievable. For decades, companies, industry bodies and regulators have been continually improving best practice guidelines for the construction and management of tailings dams. However, eliminating all catastrophic incidents remains a challenge.
The United Nations Environment Rapid Response Assessment on mine tailings looks at why existing engineering and technical knowhow to build and maintain safe tailings storage facilities is insufficient to meet the target of zero catastrophic incidents. It examines the ways in which the established best practice solutions in international collaborative governance, enhanced regulations, more resource efficient approaches and innovation could help to ensure the elimination of tailings dam failures. It uses case studies from different parts of the world to highlight the efforts of industry to reduce mine waste and stimulate new activities while suggesting how these could be accelerated through regulatory or financial incentives.
It is hoped that this report will encourage targeted action at the policy and technical level to make zero catastrophic incidents become a reality and ensure that economic prosperity is fully compatible with community health and safety.

Mining Legacies – Underestimating Life-of-Mine Across Time and Space
Authors: Pepper., Roche., C., Mudd, G
This paper commences with an exploration of mining legacies as an umbrella term for previously mined, abandoned, orphan, derelict or neglected sites. This is followed by a discussion of the current status of mining legacies as an Australia-wide issue, contrasting the Australian response with overseas examples. Common themes from past workshops are explored recognising that mining legacies are a growing public policy issue and identifying key ingredients for a successful response. Supporting this, and based on national data which re-enforces the need for action, is the changing scale and intensity of mining in Australia that, while lowering costs for mine operators, increases the liability that may eventually fall to the state if mine sites are not rehabilitated effectively. Though a national issue, mining is a state and territory responsibility, so the current approach to mining legacies is then examined state-by-state. Given the widespread application and recent changes to bonds and levies in Western Australia (WA) and the Northern Territory (
