Investment in the mining sector carries a high risk, so a comprehensive financial evaluation is required to ensure project feasibility. This study assesses the financial feasibility of gold mining investment in Pit A, PT XYZ, for the period 2025 to 2036. The purpose of this study is to evaluate the feasibility of the project through the analysis of key financial indicators such as Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PBP) using the Discounted Cash Flow (DCF) method. The DCF method was chosen due to its ability to project future cash flows and incorporate them into a comprehensive assessment of the potential benefits and risks of the project. In addition, sensitivity analysis was conducted to see the effect of changes in important variables such as revenue, cost of goods sold (COGS), and capital expenditure (capex) on the financial results of the project. The results show that the project is financially viable, with a positive NPV of US$404.16 million, an IRR of 52.10%, and a PBP of 3.32 years, all of which indicate a strong return on investment. Further sensitivity analysis shows that the project remains robust under various scenarios of changes in key variables. This study contributes to the investment evaluation literature in the mining sector by offering a more integrated approach to addressing investment uncertainty and risk through the combined use of the DCF method and sensitivity analysis.
