Westwood mine’s transformation
Through rigorous geotechnical science, operational discipline and a culture of continuous improvement, Iamgold has overcome the challenge of severe seismicity
The story of Iamgold’s Westwood gold mine in Quebec is ultimately one of resilience, disciplined decision making and long-term vision.
A few years ago, the mine, located in the Abitibi gold belt, faced significant challenges related to ground control that severely disrupted operations. Repeated seismic events, including a major one in 2020, forced the suspension of large portions of the underground mine. The operation shifted into survival mode, with constrained production capacity and limited visibility on the future.
At that point, the key question became clear: how could Iamgold regain control and build a sustainable path forward for Westwood?
The answer did not come from a single initiative, but from a deliberate pause to reassess the operation as a whole. The mine was effectively put on hold while teams reflected, challenged existing assumptions and worked collaboratively to define a new approach. This period of reset proved critical in establishing a viable long-term strategy.
The outcome was not just a technical adjustment, but a complete transformation of how the operation is managed. Iamgold developed a repeatable approach to better control Westwood’s mining environment, enabling safer and more predictable operations. Since implementing this new “recipe” in 2021, the mine has progressively regained stability and, more importantly, the company has regained confidence in the mine’s future.
Today, all areas of the mine are accessible, including zones that were previously avoided. The operation is no longer defined by its constraints, but by its ability to manage them.
This regain of control has had a direct impact on performance. Production has steadily increased, reaching nearly 114,000 ounces in 2025, supported by strong grades and improved operational consistency. In April 2026, Iamgold achieved a major milestone with the production of Westwood’s one-millionth ounce of gold since start-up—without significant disruption from seismicity in six years.
Equally important has been the cultural shift within the organization. During the difficult years, the focus was understandably on managing crises. Today, the mindset has evolved toward continuous improvement and proactive management. Teams are no longer reacting to issues; they are anticipating them and continuously refining their practices.
This transformation is clearly reflected in health and safety results. Over the past five years, the site has significantly improved its safety performance, reducing its annual Total Recordable Incident Rate from over 5 to below 1. This progress demonstrates not only improved conditions, but also stronger discipline and engagement across the workforce.
With stability restored, Iamgold has been able to refocus on building for Westwood’s future.
A major effort is under way to modernize the mine’s infrastructure and equipment. The introduction of more mechanized and automated equipment has improved productivity, efficiency and safety. At the same time, the mine is investing in digital systems, including enhanced communication networks, equipment tracking and ventilation optimization, positioning the operation for long-term performance.
Perhaps one of the clearest signs of renewed confidence is the return to exploration. A US$20 million program is currently under way to better define mineralization to the west, east and at depth. The objective is to expand resources and extend mine life, building on the now stable operating platform.
Westwood is no longer operating with a short-term survival mindset—it is planning for the next 10 to 20 years.
Beyond operational improvements, the turnaround has also translated into stronger community engagement. As the mine regained its footing, it increased its contributions locally, reinforcing its role as a responsible and committed partner in the region.
Westwood’s journey offers an important lesson for the mining industry. Complex challenges can be overcome—not through isolated technical fixes, but through a combination of strategic reset, disciplined execution and cultural alignment.
The mine’s transformation is not simply about solving past challenges—it is about establishing a foundation for sustainable growth. With improved visibility, ongoing innovation and a clear long-term perspective, Westwood is now well positioned for the future.
