Gordon Stothart, President and CEO of IAMGOLD commented, "The second quarter of 2021 was challenging primarily because production from our Rosebel mine was unexpectedly adversely affected by unusually heavy rains and an increase in COVID-19 cases in Suriname, in addition to difficult industrial relations. Essakane continued to perform strongly and we were able to finalize a new three-year collective labour agreement with our unionized employees. Westwood underground mining recommenced in the East Zone, albeit at a more tempered pace in order to accommodate enhanced safety measures in keeping with our safety-first culture. We also disclosed an increase in estimated project costs at Côté Gold, which remains on track for commercial production in the second half of 2023. As noted in our updated guidance, previously disclosed on July 22, 2021, we expect continued strong performance from Essakane in the second half of the year, while we work to recover from the headwinds at Rosebel and Westwood. We expect to disclose an initial resource at Gosselin in the fourth quarter of 2021."
