Montage pours first gold at Koné: schedule, throughput and mine-life notes for engineers

30 Second Briefing
Montage Gold has poured first gold at the Koné mine in Côte d’Ivoire on 26 September, months ahead of its original Q2 2027 target, after processing over 400,000 tonnes of ore through the oxide circuit to produce about 1,140 oz. The oxide circuit is expected to reach commercial production by year-end, with a hard-rock comminution circuit due mid-2027, supporting a planned 16-year mine life and output of more than 300,000 oz per year over the first eight years. Koné now hosts 6.29 Moz measured and indicated at 0.80 g/t Au and 2.03 Moz inferred at 0.68 g/t Au, following 380,000 metres of drilling since the 2024 feasibility study.
Technical Brief
- Self-performed construction by Montage materially cut upfront capital and compressed the overall build schedule.
- Construction started in December 2024, with first gold pour achieved less than two years later.
- Initial pour on 26 September followed continuous oxide-circuit processing from 8 September.
- Koné’s build phase generated ~3,600 jobs, with over 95% of positions filled by Ivorian nationals.
- Owner-mining model enables direct transfer of construction personnel into the long-term operating workforce.
- Once ramped up, steady-state operations are expected to support about 1,500 permanent on-site roles.
- The 2026 exploration programme totals 130,000 m of drilling, targeting higher-grade satellite deposits near Koné.
- Resource upgrades since the 2024 feasibility basis include +1.42 Moz M&I and +1.62 Moz inferred, with notable grade uplift.
Our Take
Montage Gold’s appearance in the 2026 TSX30 with a 2,502% three‑year share‑price gain suggests that bringing Koné into production in Côte d’Ivoire is being watched as a test of whether that growth profile is sustainable once the company transitions from developer to producer.
The resource upgrades at Koné reported in June (notably the 27% and 36% grade improvements in measured/indicated and inferred categories) give the mine more flexibility to absorb potential cost inflation over its 16‑year life, which is material for a low‑grade gold operation in Africa.
