Côté Gold will be an open-pit mine near Gogama, Ontario, in an established mining region with access to stable infrastructure and strong connections to local communities.
To achieve consistent and efficient operations, we are implementing autonomous haul trucks and drills as the first pieces in our technological foundation. By leveraging data and advanced analytics, we will further improve precision and operational excellence.
Côté Gold is located on Treaty 9 territory, on the traditional lands of Mattagami First Nation and Flying Post First Nation. We are also located within the traditional harvesting area of the Métis Nation of Ontario, Region 3.
