Feasibility Study (FS)
The highest-tier study — final engineering, supplier quotes, full permitting plan — at ±10–15% accuracy.
A Feasibility Study is the final tier of economic study before a construction decision. Engineering is at definitive or detailed level, supplier quotes are firm, permitting is mapped out. Accuracy is typically ±10–15%. The FS supports project financing and the Final Investment Decision. The conversion of Measured Resources to Proven Reserves typically requires FS-level confidence.
