The capital structure used is 60% own capital 40% loan capital and the discount factor used comes from the WACC calculation of 18%. The results of the analysis conducted by NPV of Rp.93,669,293,085, IRR 98% and PBP 1.07 years. Sensitivity analysis of both operations and income at a decrease of 5% to an increase of 10% shows the lowest value of NPV and IRR is Rp. 67,415,665,068 and 77% in the condition of cost of income -10% with PBP 1.34 years. This value is still above the discounted rate of 18% so it can be concluded that economically the limestone mining of PT. Semen Bosowa in the period 2022-2026 is able to continue.
