IAMGOLD Corporation announced the retirement of Mr. Ian Ashby, who has served on the company's board of directors (the board) since February 2022, and the appointment of Ms. Anne Marie Toutant as an independent director to the board. These changes are effective as of November 9, 2023. Anne Marie Toutant, who previously served on the board from December 2020 to May 2023, brings her extensive experience and expertise to the company.

Anne Marie has a profound technical background which will prove to be a significant asset as the company prepares to ramp up production at Côté Gold early next year, bringing online one of Canada's largest gold mines which will be a model for modern mining in the industry for many years to come. Ms. Toutant has a proven track record as an executive in the mining industry for over 35 years. In her career, Ms. Toutant held executive roles at Suncor Energy overseeing the initial start-up and operations of the $18 billion Fort Hills project in northern Alberta, which included the deployment and accelerated implementation of Suncor's autonomous haulage system, developing a multi-year digital transformation strategy for mining and the final reclamation of Wapisiw Lookout - the first reclaimed oil sands tailings pond in Canada.

Prior to this, Ms. Toutant held operational and technical management positions at metallurgical and thermal coal mines for Luscar Ltd. and Cardinal River Coals Ltd. and was highlighted as one of Canada's early female mine managers in 1998. These experiences contributed to her passions around safety, mentoring, sustainability, and technology. Ms. Toutant is contributing as a Non-Executive Director in the public and Non-Profit sectors.

She served on charitable and industry related boards including the Suncor Energy Foundation and the Mining Association of Canada (MAC). She is currently the Past-President of the Canadian Institute of Mining and Metallurgy (CIM) and a founding member of Women in Mining Calgary branch (WIM YYC). Ms. Toutant holds a Bachelor of Science degree in Mining Engineering from the University of Alberta and is registered as a Professional Engineer in the province of Alberta.
