World Mine Cost Data Exchange

Minecost's models and data are used by analysts in mining companies, mining equipment and consumables suppliers, and by mining engineers for a wide range of purposes such as benchmarking, competitive analysis and general forecasting. Feedback from this group of very well-informed users helps to ensure model accuracy. Other users include banks and financial institutions with specialist mining industry expertise, minerals industry research businesses, government organizations and labor unions.

The models are based on the US Bureau of Mines' Cost Estimation System and the Bureau's Lotus spreadsheet version of CES. The models have also been checked against current mine operating cost estimates prepared by professional cost estimators for a wide range of hypothetical underground and surface operations, and against real mines where costs are disclosed by the operators.

Since the models are based on engineering concepts and an accurate understanding of the mine flowsheet, Minecost uses technical papers published in the major mining engineering journals and conference proceedings. For production data, company reports and documents filed with the SEC and other regulatory authorities are used.
