Commonly, cost estimates for mining and infrastructure are much less reliable than process plants. To improve the performance of feasibility studies, they should be scrutinised through peer review and audit.

Several strategies can be used to realize the earliest positive ROI for startup open-pit mines. One of the most important strategies is to optimize the production plan by ensuring an uninterrupted ore feed and maximizing the net present value.

From estimation through to execution, all construction resources (manpower, equipment and materials) are accounted for, and project management shifts to complying with the Project Development Plan.

You should establish a realistic budget and guaranteed completion date, identify all potential risks, and do your homework before starting.
