How to Use This Calculator
- Enter waste tonnage (t) and ore tonnage (t) from the mine plan or block model.
- Set ore value per ton ($/t) and total mining cost per ton ($/t).
- Enter processing cost per ton ($/t) to calculate break-even stripping ratio.
- Review Stripping Ratio (waste:ore) and compare against Break-Even SR to assess project economics.
- Use Economically Viable (Yes/No) to make go/no-go decisions for open-pit mining phases.
