The Calculation of Recoverable Reserves

2013-4-16  calculation. This section is dedicated to the different approaches for reserves calculation. A mining operation can never recover all of the in-situ resources. Some portion of the deposit will be inaccessible or unprofitable to mine. Recoverable reserves are a subset of the resources that can be economically and technically mined.
