This study analyzes the first phase of management, applied practices and the requirements of a mining project, by interviews at 8 managers and/or directors of mining projects. The aims of the study were: to collect information on mining project management provided by managers / directors; to compare the experiences of each project with the PM BOK guide; document in the management processes the technical, environmental-permissive, political, social, and economic risks that generate delayes on the projects; identify the management approach in each of the stages of a mining project; know how the project management is developed, and contrast with the Guide to the Project Management Body of Knowledge (PMBOK® Guide) of the Project Management Institute. Each item has been contrasted with the results of an prepared interview according to the processes defined in the PMBOK®. Among the main results, it has been evidenced that managers/ directors often cannot dispose of an adequate professional team or the expert team is not enough, or that their service supply companies do not comply with the scheduled work. In addition, some technical studies such as: geotechnical, metallurgical and geological are not fully verified. Costs are often over estimates, not budgeted properly, or there are unforeseen changes that increase costs. Among the main socio-environmental characteristics, the permits do not become effective due to the strong opposition of the communities involved, being necessary to open dialogue meeting to find a conciliation between the State, the comunity and the private company. Finally, Peruvian regulations, as reported by some managers/directors, contain long and tedious processes that delay, and even extend, the approval time of a Mining Project.
