In this paper, a new non-linear heuristic approach has been developed to model variable slope angles in the open pit optimization algorithms that are based on a simple inverse distance formulation. In the primary approaches, a fixed value of slope angle is considered, and it is usually based on special block configurations such as 1:5, 1:9 and 1:5:9 patterns that suffer from creating the higher or lower angles than desired. The cone template based methods that were employed later, considered variable slope angles and improved the solution quality a little but also suffer from modeling just in non-cardinal directions. Implementation of the proposed approach on a hypothetical block model showed its capability in generating accurate and smooth pit shapes using any number of regions with different mechanical behaviors.
