PT XYZ is a tin mining company which operates in Bangka Belitung Province. The mining operations will be carried out based on the ultimate pit limit optimization result conducted previously. The next step is mine scheduling. This mine scheduling is made can by considering production target that has been determined previously,and also several economic criteria such as, Net Present Value (NPV) and Internal Rate of Return (IRR). The study is focused in region B, which has two mining blocks called Block 1 and Block 3. The mine scheduling is simulated using a software, namely GEOVIA Minesched 9.0.0. There are three scheduling scenarios which consider on the tin production target, those are 1000 tons of tin/year, 2000 tons of tin/year, and 3000 tons of tin/year. The mining production will be fulfilled simultaneously from Block 1 and Block 3 for the three scenarios. Based on the simulation that has been done, the result shows that scenario 1 with a production target of 1000 tons of tin/year has the net present value of $ 3,511,477, an internal rate of return of 16%, and payback period of 7 years. Scenario 2 with a production target of 2000 tons of tin/year has the net present value of $ 3,377,308, an internal rate of return of 17%, and payback period of 6 years. Scenario 3 with a production target of 3000 tons of tin/year has the net present value of $ 1,755,162, an internal rate of return of 15%, and payback period of 5 years.
