Once the plan has been confirmed, the real work can begin. This is the longest stage of the process so far, and can take anywhere from 10-20 years before the mine is ready for production, depending on the site size. Does a mines size affect the amount of ore produced? Measuring mine productivity can be difficult given how unique each operation is.
