Study Notes
Main Features of Mining Industry
- Mining deals with finite non-renewable resources, necessitating optimized plans to maximize net present value (NPV) over the mine's lifecycle.
- NPV is a crucial evaluation measure; a positive NPV indicates that investing in a project will enhance company value.
- NPV is calculated by discounting all cash flows to a common time, with the formula: Project NPV = SCF0 + CF1(1+i)-1 + CF2(1+i)-2 + … + CFn(1+i)-n.
- Economic acceptability of a project occurs when discounted receipts surpass discounted expenditures.
- Projects generally have a complex mineral resource, modeled using scattered samples, leading to uncertainties in deposit characteristics.
- Ore body orientations include flat, medium, and steeply dipping veins, each presenting unique extraction challenges.
- Mine locations are often remote, requiring negotiations with local authorities, adding political risks.
- The market for mining products is free and open, characterized by high transportation costs, volatile pricing, and poor market structure.
Mine Planning Stages
- Mine planning is categorized by detail: conceptual, feasibility, and operational levels.
- Timeframes in mine planning include long-term, medium-term, and short-term plans.
- Categorization by scope of actions includes strategic planning, which determines business value, and tactical planning, which focuses on execution.
- Strategic mine planning involves significant decisions affecting overall business value, while tactical planning deals with operational tasks.
- Technical decisions include mining method selection, processing routes, operation scales, mining sequences, and selective cut-offs.
Feasibility Studies
- Feasibility studies analyze all project factors to determine viability, guiding go/no-go decisions and assisting in securing financial backing.
- Phases of feasibility studies include Scoping Study, Pre-Feasibility Study, and Final Feasibility Study.
- Feasibility relates to both physical project aspects and economics, requiring justification of increasing financial commitments through the project stages.
Operations Research
- Operations research is a scientific methodology for analyzing complex problems to improve decision-making.
- Optimization seeks to find the most effective way to carry out activities, originating from Latin terms implying excellence.
- The process of optimization addresses limitations and conditions imposed by limited resources and selection criteria in decision-making.
- Solutions to optimization problems can be approached through trial and error or mathematical techniques.
