111 Overview Principal Producing Development  Highlighted Evaluation  Evaluation/Exploration  Mineral Resources and Reserves Côté Gold The Côté Gold Project is an open-pit development project owned 92.5% by a joint venture between IAMGOLD Corporation (“IAMGOLD”) and Sumitomo Metal Mining Co., and 7.5% by a third party. The project is operated by a wholly owned subsidiary of IAMGOLD. The project is located in the Chester and Yeo Townships, in the District of Sudbury in northeastern Ontario, approximately 125 kilometers southwest of Timmins and 175 kilometers north of Sudbury. Development Update The operation will employ conventional open-pit truck and loader methods. The process circuit will include primary crushing, secondary crushing, high pressure grinding rolls (HPGR), ball milling, vertical milling, gravity concentration and cyanide leaching, followed by gold recovery by carbon-in- pulp (CIP), stripping and electrowinning (EW). As at the end of December 2023, project construction at the Côté Gold Project had reached approximately 98% completion. 1 Royal Gold’s Royalty Interest Royal Gold holds a 1.0% net smelter return (NSR) royalty on all metals produced from the Chester 3 mining claims, which Royal Gold estimates to contain approximately 70% of the current reserves of the Côté Gold Project, as well as other areas outside of the current project area. Royal Gold acquired this royalty interest on June 7, 2021, from a third party.

This assumes that following initial gold production, operations ramp up early in the second quarter 2024 and commercial production is achieved in the third quarter 2024. 2 For more information, please visit: www.iamgold.com .
