IAG Boosts Westwood Mine Life & Cote Gold Stake: Is the Stock a Buy?

In This Article:

IAMGOLD IAG yesterday provided a Mineral Resource and Mineral Reserve ("MRMR") estimates and updated life of mine ("LOM") plan for its Westwood Complex located in Quebec, Canada. The life of the mine has been updated from 2025 to 2032.

On Monday, IAMGOLD announced that it has exercised the right to repurchase the 9.7% interest of the Côté Gold Mine from Sumitomo Metal Mining Co., Ltd. This takes IAG’s interest in the promising Côté Gold mine to 70%.

Let's dig deeper to analyze the significance and impact of these current developments on IAMGOLD’s prospects.

IAG Extends Westwood Life, Cuts Mineral Reserve Estimate

The Westwood Project consists of two property areas, Doyon-Westwood and Fayolle. Doyon-Westwood includes the Westwood underground mine, and Grand Duc open pit. The Westwood mine has been operating since 2014, and Grand Duc since October 2019. Open pit operations at the Fayolle deposit commenced in February 2023 and the deposit was mined out in June 2024. Grand Duc mine life is expected to conclude in 2025.

IAMGOLD has updated the life of the mine from 2025 to 2032, projecting overall average gold production at 925,000 ounces over the life of the mine, which came in lower than market expectations. However, IAG expects average gold production at an accelerated pace in the first three years, averaging 146,000 ounces.

The average estimated operating costs over Westwood’s life of mine (2025-2032) is estimated at $239.91 per ton processed. Total sustaining capital expenditures over the life of mine will be around $260.7 million. The company expects average recoveries of 95% from the processing plant with an annual capacity of 1 Mt.

The MRMR statement shows underground mineral reserves at Westwood at 2.6 million tons (Mt), averaging 11.45 grams per ton of gold containing 955,400 ounces. This is lower than the previous estimate of 3.36 MT, averaging 10.62 grams per ton of gold containing 1,149,000 ounces. While total tonnage and contained gold have fallen by 23% and 17%, respectively, the grade has slightly improved. Per the company, the updated reserves highlighted its redesigned approach to mining focusing on safety and efficiency, following the seismic activity in 2020.

Cote Gold Mine to be a Growth Driver for IAMGOLD

The Côté Gold mine started commercial production on Aug. 2, 2024. A shutdown was implemented in September to deploy operating improvements. Despite this, IAG affirmed that it remains on track to achieve the target of 90% throughput by the end of the year.

Côté Gold is operated as a joint venture between IAMGOLD (as the operator) and Sumitomo Metal Mining Co. The total gold production from Côté Gold (at 100%) is expected to be 220,000-290,000 ounces as improvements to mill availability are made during the ramp-up of operations.
