The Gibraltar Mine is an open pit copper mine located in central British Columbia, north of Williams Lake. The mine is situated on the Traditional Territories of Xatsull and ?Esdilagh First Nations and is the fourth-largest open-pit mine in North America.
The mine has been unable to discharge effluent from their tailings storage facility in recent years due to high levels of nitrate, causing large volumes of untreated water to accumulate on site. Source currently provides support to ?Esdilagh First Nation during the permitting of a water treatment plant and biological treatment trial that aim to reduce nitrate levels in effluent and resume discharge of water off site.
Source has been providing technical support on the Gibraltar project on behalf of ?Esdilagh First Nation since 2014. Source’s expertise on the project includes mine water management, treatment, discharge planning and closure planning.
