On August 6, 2026, IAMGOLD announced that expansion capital expenditures are expected to total approximately $120 million in 2026, of which $85 million is budgeted for the Côté gold mine. IAMGOLD indicated the expansion capital at Côté is to de-risk the contemplated Côté expansion, early works include basic mill infrastructure and a significant pushback to expand the operating area of the pit. IAMGOLD also stated that ore tonnes mined at Côté were 3.1 million tonnes, or 3% lower than the prior year period, due to a slightly higher strip ratio of 2.8:1 as mining activities progressed in pushback areas. IAMGOLD reported that the 2026 Gosselin zone exploration program includes approximately 10,000 metres of diamond drilling to test the north and north-east extensions of the Gosselin zone. Approximately 4,400 metres were drilled YTD with none completed in the second quarter and drilling will resume in the third quarter using the most recent drilling results obtained. IAMGOLD also stated that an infill drilling program of 20,000 metres is ongoing on the Côté zone. Approximately 6,200 metres of surface diamond drilling were completed in the second quarter 2026. The infill drilling program was planned to improve resource confidence within the northeastern extension of the Côté deposit and convert Inferred Resources into the Indicated Resources category.
