Water and the Mining Industry
Unfortunately, existing tools, while useful for a general comparison of companies and locations, are inadequate for detailed, asset-level risk assessment and management.
The Columbia Water Center has received a 3-year grant from Norges Bank to develop a modeling platform to quantitatively assess mining-related water and environmental risks and their financial implications. For the initial phase of the project, the Center’s research team will focus on water-related exposure for the mining of copper and gold.
The new modeling platform will allow investors access to a targeted analysis of water-related mining risk, with a high level of specificity related to type of mining operation, geophysical and socio-political setting, remediation and mitigation needs, financial implications of particular asset risks on the broader company portfolio, and causal connections between risk factors and financial performance. A comprehensive database will be developed as part of the project to support these analyses. Norges Bank has initiated and actively supports this academic research project to increase understanding of environmental risks and their financial implications as part of its responsible investment strategy.
The project will use modeling tools to address elements of specific risks as well, including: meeting water requirements for mineral processing, energy production and community needs; treatment, disposal and re-use of wastewater; flooding and mine dewatering operations; and addressing accidents and spills. The role of rights, regulations and related governance issues as it poses financial risks to mining operations is also considered.
The model will be developed using the relatively data-rich settings in the USA, Canada, Chile and Australia. The research team plans to cross-validate model performance to test the application of the models to settings where data is less abundant. Applications will then be tested and in other regions such as South Africa and Peru, where geophysical and mining conditions are similar but where data might not be as readily available and where there may be differences in economics, governance and other site factors. Portfolio risk analysis tools are being developed for the analysis of financial risk at the asset, company and regional levels.
The data and models being developed are open source, and–subject to restrictions from the data providers– will be available to mining companies seeking to assess, manage and mitigate a broad range of environmentally induced financial risks. Other targeted users include financial analysts, mining companies, government regulators, NGOs and academics.

“While a new administration in Washington has shifted toward deregulation of the mining industry, an opposing trend is taking root in jurisdictions around the world. A number of national and local governments are tightening environmental regulations and shutting down specific mining projects, or in some cases the entire industry, due to environmental risks, including those related to water use and pollution.”

“Across the nation, thousands of abandoned mines remain nearly as they were left when they ceased to be operational. In many cases these mine sites continue to pollute the environment for decades as acid mine drainage flows into rivers and streams. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) was enacted in 1980 to enable the federal government to manage such industrial pollution. But through lack of funding and enforcement, the public has been stuck with the cleanup bills.”

“The Columbia Water Center submitted a letter in support of the proposed changes to the rules and encouraged disclosure on many factors related to water risk, including a mine’s capacity to maintain its social license to operate, its risk of tailings dam failure in the light of increasing extreme weather events, and its ability to live up to its own predictions of water quality during the mine’s operation and closure.”

“Under the proposed rules, mining companies must submit a “technical report summary” for each mineral resource or reserve that is significant enough of an asset to be considered material. The SEC outlined specific requirements for the contents of the technical reports, including, most relevantly: ‘the final identification and detailed analysis of environmental compliance and permitting requirements, including the finalized interests of agencies, NGOs, communities and other stakeholders, together with the completion of baseline studies and finalized plans for tailings disposal, reclamation and mitigation.’”

“Rule 10b of the Securities Exchange Act gives shareholders the right to bring a lawsuit to recover economic loss sustained as a result of fraud related to the trading of their investments in stocks or bonds. This fraud can come in many forms, including insider trading, price fixing or corporate misrepresentations to its investors. This last type of fraud has seen increased attention (primarily at the state level) from those who want to see corporate statements regarding future environmental liabilities, including climate change impacts.
In the past year, lawsuits against three different foreign-owned mining companies operating in South America were brought in U.S. courts regarding mismanagement and lack of disclosure of environmental risk.”

“Early this year, a federal court agreed with environmental advocates that the Environmental Protection Agency (EPA) must take steps to ensure that mining companies pay for their own harmful environmental impacts so the taxpayer is not stuck with the bill. The Court of Appeals for the D.C. Circuit affirmed a settlement agreement between the EPA and several environmental groups that establishes a timeline for the creation of financial assurance requirements for certain hazardous industries, starting with hardrock mining.”

“The Columbia Water Center is undertaking a three-year project to quantitatively assess mining-related water and environmental risks and their financial implications. This research is generously supported by Norges Bank Investment Management.”

“The mining industry accounts for 12 percent of the Peruvian economy and 60 percent of Peru’s total exports. The government of Peru faces significant pressure to encourage growth and investment in this sector, especially in the face of falling commodity prices. But this has also put pressure on the government’s ability to properly assess environmental impacts.”
