What is a tailings storage facility, and how will it work at Donlin Gold?
Tailings are the material left after gold is separated from mined rock. Donlin Gold’s proposed tailings storage facility will be designed to safely contain and manage that material over the long term. The facility will use a downstream rockfill dam built on bedrock, along with a synthetic liner and systems to collect and manage water. It is engineered to withstand a large-magnitude earthquake and will be regularly monitored and inspected throughout operations.
When mining is complete, water will be removed from the facility, and the tailings will be covered with rock and soil and revegetated.
