IAMGOLD Pre-Announces Q3 Côté Output of 64,400 oz; 2026 Guidance to Land at Low End

summarizeSummary

Côté produced 64,400 attributable ounces in Q3 2026, leaving full-year output tracking to the low end of the 270,000-310,000 oz range. Record mining volumes and above-nameplate September throughput offset the softer guidance, with an expanded mine plan and reserve estimate due in Q4.

The headline is that Côté's ramp-up is tracking at the bottom of the guided band rather than the middle. Q3 attributable production came in at 64,400 ounces (92,000 oz on a 100% basis), leaving year-to-date output at 184,000 attributable ounces against a 270,000-310,000 oz full-year range, so management now expects the low end. The offset is operational. This was the first full quarter without contractor crushing, and the mine set a quarterly mining record of 12.4 Mt while averaging a record 37,100 tpd in September, above the 36,000 tpd nameplate. Recoveries slipped to 90% on Vertimill downtime, and a third Vertimill is due in early 2027. The bigger item is the updated Côté mine plan and reserve estimate due in Q4 2026, which management says will show a significant reserve and life-of-mine expansion and support sustained throughput near 40,000 tpd. Because Côté is the company's growth engine, both the low-end guidance and the pending reserve study drive the story.
