Toronto, Ontario--(Newsfile Corp. - June 16, 2020) - IAMGOLD Corporation (TSX: IMG) (NYSE: IAG) ("IAMGOLD" or the "Company") advises that seven personnel at its Rosebel Gold Mine operation in Suriname ("Rosebel") have been diagnosed with COVID-19. The individuals have been quarantined and are receiving medical care as appropriate. Disinfection of their living quarters and work areas, along with contact tracing, is ongoing. This is the first time Rosebel has experienced positive cases.

IAMGOLD has taken extensive steps, at Rosebel and across its operations and offices, to protect the health and safety of employees, contractors and local communities in response to the global COVID-19 crisis. At Rosebel, these steps include: social distancing, implementation of all sanitary measures in close communication with health authorities, site access triage process, reduction of the on-site workforce to essential services only and additional busses and medical personnel.

The Company additionally advises that the Rosebel Union has unfortunately chosen to use one of these preventative measures, which would support social distancing by reducing the number of people sharing accommodations, as the basis for a work stoppage. Due to Union resistance to the implementation of COVID-19 control measures, we are suspending operations until the appropriate controls are in place to protect the safety of all employees.

Rosebel's management team was in regular communication with the Union until the work stoppage. The team has ongoing communications with employees, health authorities and the community regarding COVID-19 preventative measures and the work stoppage.

Rosebel's management team is actively taking steps to resolve the situation. Rosebel remains committed to ensuring the health and safety of its employees, contractors and communities.
