Round 1

Reviewer 1 Report

1) A very well prepared paper and a great contribution to the extractive metallurgy community.

2) The NPV enhancements are quite applicable and offer the opportunity to improve both efficiency, yield  and reduce operating cost.

3) The case example nicely defines the enhancements and improves the confidence in the spatial distributions. 

4) It is suggested that additional core samples be in the plan. The additional sampling should be reflected in the cumulative NPV calculation throughout the life of the mine. Certainly, this could be a focus in another paper.

5) The positive impact on the carbon footprint should be emphasized in the paper quantitatively, if possible.

6) Note spelling error on line nos. 174  "Strategic Plan"

7)  Hopefully this work will stimulate other researchers to test the new method for their specific mining operation.

Reviewer 2 Report

In this study, a simultaneous optimization of a system composed of the mine planning and the metallurgy plant was proposed. It incorporates different types of ore and geological uncertainty and is successfully applied to a case study. More experiments should be conduct to expand the usable range under different ore types and grade. The contents were well arranged and presented; this work can be published in the present form.
