$\begin{array}{l}\displaystyle \mbox{NPV} = - \mbox{I}_0 + \sum_{i=1}^n \frac{\mbox{FCF}_i}{(1+r)^i}\end{array}$

$\begin{array}{l}\displaystyle \mbox{PI} = \frac{1}{ \mbox{I}_0 } \cdot \sum_{i=1}^n \frac{\mbox{FCF}_i}{(1+r)^i}\end{array}$

$\begin{array}{l}\displaystyle \mbox{FCF}_i = \left( \mbox{REV}_i - \mbox{COST_i} \right) \cdot \left( 1 - \mbox{TAX}_{\mbox{income}} \right)\end{array}$

$\begin{array}{l}\displaystyle \mbox{REV}_i = \mbox{q}_i \cdot \mbox{INCOME_PRICE}\end{array}$

$\begin{array}{l}\displaystyle \mbox{INCOME_PRICE} = \mbox{MARKET_PRICE} \cdot \left( 1 - \mbox{MINING_TAX} \right)\end{array}$

$\begin{array}{l}\displaystyle \mbox{COST}_i = \mbox{COGS}_i + \mbox{OPEX}_i\end{array}$

$\begin{array}{l}\displaystyle \mbox{COGS}_i = \mbox{q}_{L,i}^{\uparrow} \cdot \mbox{COST/qL} + \mbox{q}_{O,i}^{\uparrow} \cdot \mbox{COST/qO}+ \mbox{q}_{G,i}^{\uparrow} \cdot \mbox{COST/qG} + \mbox{q}_{W,i}^{\uparrow} \cdot \mbox{COST/qW} + \mbox{q}_{WI,i}^{\downarrow} \cdot \mbox{COST/qWI}\end{array}$
