Bankable Feasibility Study (BFS)
Typically a study of all aspects of a project (mine plans, infrastructure, environment & community etc), also including costs +/- 15%. Used to assess whether a project is viable or not.
More detailed than a Preliminary Feasibility Study (PFS).

Fairly important to get your head around these terms if you're investing in exploration/development stocks.
