The Côté Gold Project is located in the Chester and Yeo Townships, District of Sudbury, in northeastern Ontario. It is approximately 25 km southwest of Gogama, 125 km southwest of Timmins, and 175 km northwest of Sudbury, roughly 5 km west of Highway 144.

The Project area is characterized by gentle hills, forests, lakes and rivers. The Project area is located on two subwatersheds, the Mollie River system and the Mesomikenda River system. Additionally, the continental watershed divide is located south of the Project property, with the nearest boundary located southwest and more than 3.5 km from the proposed open pit location. Land use in the area consists of recreational activities by locals and tourists, including fishing, camping and hunting. It is also extensively used for sustainable harvesting of timber.


IAMGOLD acquired Trelawney Mining and Exploration Inc. in 2012. Trelawney had carried out exploration activities at the Project site since 2009.

Exploration activities have been ongoing in the area since the early 1900s by various companies and government agencies. More concentrated mineral exploration efforts were conducted in the early 1940s and from the early 1970s to about 1990.

Since its discovery in 2010, extensive diamond drilling activities have been undertaken to delineate the Côté Gold deposit.
