Lane developed the theory that a relationship exists between cut-off grade and NPV. According to the theory there is a cut-off grade (that may vary over the life of the mine) for which the Net Present Value is optimised. Lane's theory is clarified by the function defining ( F_ {n} ), the cash flow in period n.

The open pit mine optimization problem is concerned with the scheduling of mining activities over the life of an open pit mining project. Two variants of the problem commonly solved are (i) the ultimate pit limit problem and (ii) the open pit phase design problem. A closely related problem is the open pit production scheduling problem.
