This is a mining enguneering question:The following cost information has been provided for pit optimization for Rocktype $1$ and Rocktype $2,$ but should be reviewed as it may not all be associated with pit optimization. A flotation processing plant with the annual mill capacity of $8M\frac{t}{?}$ year exists and the operation is mill limited$.$

Calculate the following cost items for pit optimization purposes in Whittle:

I. Reference mining cost

II$.$ Rock type mining cost adjustment factors

III. Ore mining costs for RT$1$ and RT$2$

IV$.$ Time costs

V$.$ Ore processing costs for RT$1$ and RT$2$
