Maximizing Project Value using a Multi-Scenario Deterministic Economic Model – A Case study of Silver-Lead-Zinc Project in Peru

In the current difficult financial markets, only the best projects will advance to the next phases of development due to limited funding. Projects are consistently being evaluated by their initial Capital Expenditure (CapEx), Net Present Value (NPV), and Internal Rate of Return (IRR). Optimizing these parameters is the best way to gain market interest. Global Resource Engineering LTD (GRE) completed an optimization study for a silver-lead-zinc project in Peru. In this sense, the objective of the study was to minimize the project initial Capital Expenditure while maximizing the Net Present Value and Internal Rate of Return. GRE accomplished this goal by completing a series of tradeoff studies for the project and combining them through the use of a multi-scenario deterministic model to find the most economic scenario.
