“Today’s announcement marks the culmination of a shared vision between Northern Superior and IAMGOLD to create a truly unified and world-class gold camp near Chibougamau, Québec. I’m immensely proud of our team and what we’ve accomplished together in bringing this vision to life.
“I also want to thank our shareholders for their trust and support. I’m genuinely excited that they will now become shareholders of IAMGOLD, a company with extraordinary momentum, powered by a leadership team that has flawlessly executed the development of the now-iconic Côté Gold Mine, a highly strategic operation located in one of the world’s most sought-after mining jurisdictions. Backed by this unique, repeatedly proven, and Québec-rooted expertise, IAMGOLD will now be able to fully unlock the value of a unified camp and build it into Québec’s next major mining complex, with far-reaching economic and social repercussions across the province.
“Finally, this transaction enables our shareholders to benefit from the distribution of the shares of our spin-off company, ONGold Resources, which is rapidly advancing the Monument Bay and TPK projects, the latter being Northern Superior’s former flagship asset,” commented Simon Marcotte, President and Chief Executive Officer of Northern Superior.
“The addition of Northern Superior’s assets to IAMGOLD’s Nelligan Mining Complex in the Chibougamau region of Québec is extremely exciting for IAMGOLD, the region and our mutual shareholders,” said Renaud Adams, President and Chief Executive Officer of IAMGOLD. “This acquisition aligns with our strategy to become a leading Canadian-focused mid-tier gold producer, bolstering our organic pipeline in Québec where we have maintained a longstanding presence. Further, the combined assets begin to define a conceptual project that complements both the scale and timing of our Côté Gold Mine and its forthcoming expansion. We look forward to accelerating our exploration program in the region with a goal of further expansion and extension of the mineralization at Nelligan, Philibert and Monster Lake – making the Nelligan Mining Complex already near the top undeveloped projects in mining-friendly Québec and Canada.”
