The Horizon North Mine Expansion Project is a long‑term oil sands mining growth option at Canadian Natural Resources Limited’s (CNRL) Horizon operation that is intended to add roughly 90,000 bbl/d of incremental bitumen production capacity, with an indicated capital range of about $4.5–$5.5 billion. CNRL has framed the project as an integration of two previously advanced concepts—an In‑Pit Extraction Plant (IPEP) and a high‑temperature paraffinic froth treatment (PFT) facility—into a single expansion package aimed at improving recovery and processing efficiency at the mine. The company has indicated a multi‑year development horizon (about seven years) and noted that new provincial regulatory approvals would be required, with FEED activity contemplated in 2026 as part of its longer‑dated oil sands expansion pipeline.
