IAMGOLD Announces Closing of Northern Superior Acquisition
IAMGOLD Consolidates Chibougamau Gold Camp via Total Acquisition of Northern Superior Resources
On December 19, 2025, Northern Superior Resources Inc. ("Northern Superior") and IAMGOLD Corporation announced the successful closing of the previously announced plan of arrangement. IAMGOLD has acquired all issued and outstanding common shares of Northern Superior. Under the terms of the agreement, Northern Superior shareholders received CAD $0.19 in cash and 0.0991 of an IAMGOLD common share for each Northern Superior share held. Additionally, shareholders received a special distribution of approximately 0.1957 common shares of ONGold Resources Ltd. ("ONAU") for each Northern Superior share. Northern Superior is now a wholly-owned subsidiary of IAMGOLD, and its shares are being delisted from the TSX Venture Exchange.
This is a terminal event for Northern Superior as a standalone public entity. The impact is a "Game Changer" as it marks the successful exit of the company through a strategic buyout by a mid-tier producer. - Consolidation: The deal merges the Nelligan, Philibert, and Monster Lake projects into a single "Nelligan Mining Complex," creating one of the largest pre-production gold hubs in Canada. - Value Realization: The deal represented a significant premium (initially cited as 45% over the market price) and provided shareholders with immediate liquidity (cash), equity in a larger producer (IAMGOLD), and continued exploration exposure through the spin-out of ONGold Resources. - Operational Continuity: IAMGOLD intends to accelerate exploration at Philibert and Nelligan to feed a potential centralized mill, a strategy Northern Superior management had advocated for throughout 2025.
Northern Superior was a gold explorer focused on the Chibougamau Gold Camp in Quebec. Its flagship project was Philibert, located 9 km from IAMGOLD’s Nelligan project. During 2025, the company expanded Philibert through a 20,000-metre drill program, identifying new high-grade footwall and hanging wall zones (e.g., 11.99 g/t Au over 9.1m). The property was 75% owned by Northern Superior and 25% by SOQUEM (with an option for Northern Superior to buy the remaining 25%).
