This site is a one-stop source of mine cost spreadsheet models and operating cost information based on verifiable engineering and production data and peer review by mining industry analysts from around the world. Operating cost data is verified against publicly available information and our own sources and then used to construct detailed engineering-based mine cost models of all of the world's major metals mines. These models are available for download by registered minecost.com users. The models are in Microsoft Excel spreadsheets with embedded cost curve charts. Each downloadable spreadsheet model contains detailed production data and mine economics for historical years back in many cases to 1991 and projections for future years to 2006. All models have cost curves showing the operation's comparative cost ranking against all other mines in the industry. The models have been extensively road-tested by minecost.com users. We do not make up data simply to produce a result. We only model mine costs when we have good data. We only model mine costs when we understand the flowsheet. The models come in two versions. For all mines we have a "hard-wired" model without formulas. We also have "editable" versions of the models that contain all the necessary formulas to allow users to change most of the operating inputs and assumptions and make projections out to 2010. Contributors and users who are able to provide valuable feedback and corrections to our models are entitled to download credits from this site. See more on how we construct our cost models.
