GOSSELIN (1.35% NSR)

On October 15, 2024, IAMGOLD announced diamond drill results outlining the successful extension of mineralization outside of the Gosselin December 31, 2023 mineral resource pit shell. Key extensions have been intersected south and west of the Gosselin West Breccia, and at depth between the Côté and Gosselin West Breccia in an attempt to connect the two zones. Highlights of the Gosselin drill program include:

• 0.96 g/t gold over 368.8 meters

• 1.1 g/t gold over 357 meters
• 1.19 g/t gold over 201 meters

Renaud Adams, President and Chief Executive Officer of IAMGOLD, commented: “We believe that Côté is just the start of what will be a mining district. The exploration results today from Gosselin continue to demonstrate the potential for the Côté and Gosselin Zones to connect, in addition to highlighting that the overall size and scope of these zones have yet to be defined – as both Côté and Gosselin remain open at depth in all directions.”

On February 15, 2024, IAMGOLD announced the updated Gosselin mineral resource estimate of 4.4 M Indicated gold ounces at 0.85 g/t and 3.0 M Inferred gold ounces at 0.75 g/t. Exploration drilling for the remainder of 2024 will continue to target mineralization beneath both Gosselin and Côté.
