IAMGOLD Defers Côté’s $500–750 Million Step-Up to Study a 70,000-tpd Build

IAMGOLD has changed the question at Côté Gold from whether the Ontario mine can reach nameplate throughput to how large it should ultimately become.

The company’s second-quarter results showed Côté operating near its 36,000-tonne-per-day nameplate rate in June after a conveyor replacement and commissioning of a second cone crusher. IAMGOLD produced 188,100 attributable ounces across the group in the quarter, generated $507.3 million of adjusted EBITDA and $368.9 million of mine-site free cash flow, while ending June with $1.35 billion of available liquidity and a modest net-cash position excluding leases and letters of credit.

That stronger financial footing is allowing management to rethink a costly intermediate expansion. IAMGOLD had previously been working toward a 50,000-55,000 tpd Côté configuration. It is now prioritising debottlenecking toward roughly 40,000 tpd and evaluating a much larger long-term case of about 70,000 tpd. The change defers an estimated $500 million-$750 million of spending associated with the former expansion concept.

The reason is geological scale. A June resource update combined Côté, Gosselin and the saddle area into one model containing 20.3 million ounces of measured and indicated gold resources on a 100% basis, plus 3.5 million inferred ounces. IAMGOLD owns 70% of Côté, with Sumitomo Metal Mining holding 30%. The revised resource used a $2,500 gold-price assumption and a 0.25 g/t cut-off, so not all of the headline increase represents new drilling; higher price assumptions and a broader pit shell contributed to the uplift.

The operational case still has to catch up with the resource case. Côté’s first-half attributable production was 119,600 ounces, against full-year guidance of 270,000-310,000 ounces. IAMGOLD expects a stronger second half as throughput improves and grades rise, but year-to-date Côté cash costs excluding royalties were $1,301 an ounce versus full-year guidance of $900-$1,050. The mine therefore needs sustained plant performance and lower unit costs before a much larger expansion can be underwritten with confidence.

Management has already improved the balance sheet ahead of that decision. In June, IAMGOLD increased its revolving credit facility to $850 million, extended maturity to 2030 and retained a $250 million accordion. The facility was undrawn at quarter-end. The company also bought back $147.9 million of shares during the second quarter and repaid the remaining $100 million drawn on its revolver.

Côté is not the whole company. Essakane in Burkina Faso remains IAMGOLD’s largest current producer, contributing 183,500 attributable ounces in the first half, while Westwood produced 68,600 ounces. That diversification helps fund Côté, but it also leaves IAMGOLD exposed to jurisdictional risk in Burkina Faso and to the challenge of allocating capital between a mature African cash generator, Westwood and a potentially much larger Canadian flagship.

The next major catalyst is the fourth-quarter Côté technical report and updated mine plan. Investors will be looking for three things: how much of the 20.3-million-ounce measured-and-indicated resource converts into reserves, whether the 70,000-tpd concept produces superior returns after infrastructure and permitting costs, and how quickly the existing plant can hold 40,000 tpd without sacrificing recovery or reliability.

For IAMGOLD, the strategic shift is important because it postpones a large cheque while preserving a bigger prize. But the value of that option now depends less on resource size than on proving that Côté can operate consistently, lower costs and generate enough cash to finance expansion without recreating the balance-sheet pressure that accompanied its original construction.
