Course Description
GRM 2102
The course introduces mineral mineral exploration and mining methods. It focuses on the exploration of ore deposits from desk studies studies up to harnessing harnessing of the mineral mineral deposit. The various various methods of exploration exploration are treated treated in detail. detail. Methods of sampling of ore, grade and tonnage calculations are also tackled, culminating into the various mining methods and examples of classic ore deposits world-over.

Duration o( Course
The course is taught to the second &ear students students in one 1+-week 1+-week semester. semester. It is a 3 credit unit course. It involves 2 hours of lectures and 1 contact hour for practicals per week.
Mode o( )nstruction •
& lectures and use of wall charts for the various ore minerals.
•
)itation of case studies of exploration of some classical mineral deposits.
•
ecturer asks *uestions or for students opinion during the lectures in order to incite them into active participation.
•
/fter the preliminar& lectures, the students start em%arking on the practicals during the third week. These involve the various ore mineral collections in the 0epartment.
•
"tudents are taken out of the lecture rooms to demonstrate the various stages of mineral exploration.
•
Time is spent in the geochemistr& la%orator& to learn the assa& methods.
•
The practicals and assa& results are assessed.
•
"tudents are given assignments after ever& maor topic.
•
"tudents sit a course test after the eighth and fifteenth weeks.
•
The students spend 212 weeks in the field during the recess term.
