Optimising Open Pit to Underground Cut

Given that underground mining profits are less dependent on depth there will likely be a point where the marginal profit of the underground exceeds that of the open pit. Using this method the cut-over point is the depth at which the marginal profit from the open-pit is equal to the marginal profit from the underground.
