The student will be required to carry out a project related to his/her subject/field of specialization. A course in report writing is included. The project is used to make the student apply the practical and theoretical knowledge obtained during the course. It will normally consist of either a review of a relevant topic or a practical project with data being generated from experiments performed by a student in industry or university and it will also incorporate student seminars in which the student is required to present papers on any mining related subject. Performance will be based on a formal report and an oral examination.
