IAMGOLD Announces Sponsorship of Key Community Initiatives

Toronto, Ontario--(Newsfile Corp. - April 29, 2021) - IAMGOLD Corporation (TSX: IMG) (NYSE: IAG) ("IAMGOLD" or the "Company") is pleased to announce the following initiatives, in reflection of the Company's Zero Harm® vision and commitment to Diversity:

UNICEF International ACT-A / COVAX Emergency Response

In response to the urgent need for COVID-19 vaccinations globally, IAMGOLD contributed $250,000 to UNICEF to support the ACT-A / COVAX Emergency Response in West and Central Africa. ACT-A (Access to COVID-19 Tools Accelerator) is a global collaboration to accelerate the distribution of COVID-19 vaccines, to strengthen core health systems, to assist low and middle income countries beyond the pandemic and to mitigate the public health and economic impact of COVID-19. This donation is a continuation of the Company's contributions to support host countries and local communities in response to the global COVID-19 pandemic. IAMGOLD operates the Essakane Gold Mine in Burkina Faso, the Boto Gold development project in Senegal as well as exploration projects Diakha-Siribaya in Mali and Karita in Guinea.

"UNICEF is proud to be leading the global delivery of COVID-19 vaccines along with corporate partners like IAMGOLD. IAMGOLD's generous contribution will play a key role in helping us ensure safe, fast and equitable access to vaccines, tests and treatments, across West and Central Africa," said David Morley, President and CEO of UNICEF Canada. "Together, we are investing in strong health systems that ultimately train frontline health and social workers around the world to support the children and their families left ever more vulnerable by the pandemic."

Giants of Africa

In partnership with Giants of Africa (GOA), IAMGOLD is investing $1,000,000 in a 4-year program starting in Summer 2021, aimed at encouraging the development of youth through the power of sport. The program includes: the construction of basketball courts in IAMGOLD's host communities of Burkina Faso, Senegal and Mali, multi-day basketball and life-skills camps in each region as well as two-day mentorship camps, and a women's empowerment career workshop in Senegal. Through this strategic partnership, GOA and IAMGOLD hold a shared belief that Africa's vibrant youth possibilities are endless if they are given the tools to be inspired and visualize opportunities for their future.

"We are appreciative of IAMGOLD's commitment to the next generation of African leaders. With this long-term partnership we're excited to reach even more youth across the continent through education and sport and encourage them to dream big," said Masai Ujiri, Toronto Raptors President & Giants of Africa Founder.
