First Mining Gold Corp Submits NI 43‑101 Pre‑Feasibility Study for Springpole Project
On 23 December 2025, First Mining Gold Corp. (TSX: FF) announced that it has filed an independent technical report and pre‑feasibility study (PFS) for its wholly owned Springpole gold project in Ontario, Canada. The submission, titled “Springpole Gold Project NI 43‑101 Technical Report and Pre‑Feasibility Study, Ontario, Canada,” was lodged with SEDAR+ and is available to the public.
The report was prepared by Ausenco Engineering Canada ULC of Vancouver, a company experienced in mining engineering and environmental consulting. It conforms to the Canadian Association of Mining, Metallurgical, and Petroleum Technology (CAMPT) standards for NI 43‑101 disclosures, providing detailed mineral resource estimates, preliminary metallurgical data, and a high‑level cost framework for the project.
Key Highlights of the Springpole PFS
