1 The metrics provided under the “2021 Technical Report” column are based on the Extended Case cited in the 2018 Technical Report, updated as discussed above. Years 1 to 5 average annual production commence on commercial production.

2 The 2021 Technical Report reflects higher cash costs and all-in sustaining costs (“AISC”), primarily due to an overall increase in estimated operating costs due to inflation, increased workforce costs, maintenance equipment costs and royalties (included in AISC) which vary with the gold price.

3 Sustaining and expansion capital variances between the 2018 Technical Report and the 2021 Technical Report primarily represent the reclassification of capitalized waste stripping from sustaining capital to expansion capital in accordance with World Gold Council guidelines and equipment leases relating to initial mining fleet.

History

IAMGOLD acquired Trelawney Mining and Exploration Inc. in 2012. Trelawney had carried out exploration activities at the Project site since 2009 prior to the acquisition.

Exploration activities have been ongoing in the area since the early 1900s by various companies and government agencies. More concentrated mineral exploration efforts were conducted in the early 1940s and from the early 1970s to about 1990.

Since its discovery in 2010, extensive diamond drilling activities have been undertaken to delineate the Côté Gold deposit.
