IAMGOLD (TSX: IAG) is making major moves this morning to consolidate an entire mining district. The company has announced the acquisition of both Northern Superior Resources (TSXV: SUP) and Mines D’Or Orbec (TSXV: BLUE) as part of an effort to secure the entire Chibougamau region of Quebec.
Northern Superior is the key to the consolidation of the region, with its Philibert, Chevrier and Croteau properties essential in establishing what is being referred to as the Nelligan Mining Complex. The Complex, which will also include IAMGOLD’s own Nelligan and Monster Lake projects, is to be one of the largest pre-production gold camps in the country, with measured and indicated mineral resources of 3.75 million ounces of gold and further inferred resources of 8.65 million ounces of gold.
The acquisition of Mines D’Or Orbec will also add the Muus Project into the mix.
Collectively, IAMGOLD will have added Northern Superior’s 70,636 hectares of claims and Mines D’Or Orbec’s 24,979 hectares of claims to their own 38,403 hectares, establishing a massive footprint within the district.
Under the terms of the arrangements, Northern Superior shareholders are to receive total consideration of $2.05 per share, valuing the company at $375 million, a 45% premium to Friday’s closing price. Consideration is to be a mix of cash and shares, consisting of 0.0991 of a share of IAMGOLD and $0.19 in cash for each share of Northern Superior.
Northern Superior shareholders meanwhile as part of the arrangement will see all common shares of ONGold Resources (TSXV: ONAU) held by Northern Superior distributed to shareholders on a pro-rata basis.

“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,” commented Simon Marcotte, CEO of Northern Superior.
“The addition of Northern Superior’s assets to IAMGOLD’s Nelligan Mining Complex in the Chibougamau region of Quebec is extremely exciting for IAMGOLD, the region and our mutual shareholders,” commented Renaud Adams, CEO of IAMGOLD.
“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 Quebec and Canada.”

Mines D’Or Orbec shareholders meanwhile receive consideration of $0.125 per share, amounting to $0.0625 in cash and 0.003466 shares of IAMGOLD for each share of Mines D’Or Orbec held. The figure represents a price tage of $17.2 million, and a premium of roughly 25% to Friday’s close.
The transactions are expected to close in the fourth quarter of 2025, or in the first quarter of 2026.
IAMGOLD last traded at $18.76 on the TSX.
