ThreeDify OptimCut (OptimCut) is a GUI based interactive cut-off grade optimization tool. It uses a Dynamic Programming algorithm to determine the optimum yearly cut-off grades and production rates for either open-pit or underground mines. OptimCut features both standard and constrained optimization modes, and outputs N-best solutions in terms of Net Present Value (NPV). OptimCut's rich GUI interface will assist mine planners in exploring their own custom policies.

Determining mine-mill cutoff grades and production rates is a fundamental task for strategic mine planning. OptimCut is simple and cost effective. It is an ideal tool for mine planners who frequently need quick and reliable answers to "what if?" questions.

• Powerful: maximizes the Net Present Value (NPV) throughout your entire mine-mill life with N-best solutions.
