Summary:
Côté is one of Canada’s largest gold mines, with an expected average annual production of 495,000 ounces and a total all-in sustaining cost of US$760 per ounce over the first six years of operation. Commercial production was declared in August 2024, and IAMGOLD continues to ramp up toward nameplate capacity, targeted for the end of Q4 2025. Together, the Côté and Gosselin deposits host a Proven and Probable Mineral Reserve of 7.34 million ounces, a Measured and Indicated Resource of 16.21 million ounces, and an Inferred Resource of 4.16 million ounces, making the complex one of the largest gold resources in Canada.
IAMGOLD is advancing technical studies on Gosselin, including metallurgical testing and mining and infrastructure studies, to assess options for incorporating the Gosselin deposit into a future Côté Gold life-of-mine plan. An additional 45,000 meters of drilling is planned at Gosselin in 2025, with both deposits remaining open at depth.
On October 15, 2024, IAMGOLD announced positive diamond drill results from its 40,400-meter exploration program, successfully extending mineralization beyond the Gosselin December 31, 2023 Mineral Resource pit shell and highlighting the potential to connect the Côté and Gosselin deposits. Key intercepts include 0.96 g/t gold over 368.8 meters, 2.70 g/t gold over 235 meters, 1.10 g/t gold over 357 meters, and 1.19 g/t gold over 201 meters. Extensions have been identified to the south and west of the Gosselin West Breccia and at depth between the Côté and Gosselin West Breccia zones.
IAMGOLD disclosed on August 7, 2025 that it plans to drill a total of 45,000 meters at Gosselin in 2025 and expects results from the 2024 and 2025 Gosselin exploration programs to be incorporated into an updated Mineral Reserve and Resource estimate in 2026, as well as an updated technical report, considering a larger-scale operation with a conceptual plan targeting both the Côté and Gosselin zones. IAMGOLD expects the updated technical report to be completed by year-end 2026.
