Location
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. The project is accessible year round via Highway 144 which runs north-south 5 km to the east. The Côté Gold properties were assembled through staking and option agreements covering a total area of about 596 km2.
Côté Gold is located on Treaty 9 Territory, on the traditional lands of Mattagami First Nation and Flying Post First Nation, and within the traditional harvesting area of the Métis Nation of Ontario, Region 3.
Project Status
As of March 31, 2023, overall, the project was estimated to be 79.8% complete. Please refer to the May 11, 2023 news release
and 2022 Technical Report for more detail.

1 Costs to complete, NPV5%, IRR and payback period are on a go forward basis and exclude
sunk costs up to May 1, 2022.
2 This is a non-GAAP financial measure. Please refer to “Non-GAAP Financial Measures” at the end of the news release dated August 3, 2022.
3 Project costs incurred until May 1, 2022 at 1.27 CADUSD and project costs from May 1, 2022 and operating costs at 1.25
CADUSD.
4 The updated metrics are based on what was previously known as the Base Case (203 Mt) plus the Extended Case (30 Mt). The Extended Case mine plan, supported by exploitation of the total Mineral Reserves estimate, includes 233 million tonnes compared to the Base Case of 203 million tonnes over the LOM and adds two additional years to the Base Case mine life without expanding the footprint of the Project. Years 1 to 6 average annual production commence on commercial production.

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