For investors and financial institutions, water risks in the mining sector are difficult to track.
This summer, while Americans focused on the BP oil spill, disaster struck at a copper mine in southeastern China. The mine, owned by China’s largest gold producer, Zijin Mining Group, leaked 2.4 million gallons of waste water laced with acidic copper into the Ting River, killing 2,000 metric tons of fish – enough to feed 72,000 residents for a full year.
Just as the Deepwater Horizon disaster reminds us of the underlying risks of offshore oil drilling, the Zijin disaster demonstrates the environmental risks associated with the thousands of hardrock mineral mines in operation around the world. And, as a new paper from WRI concludes, current reporting practices mean that investors and financial institutions may not be fully aware of these risks, even though they may suffer the consequences.
