1. Remobilisation of ore deposits As many ore deposits formed many hundreds to thousands of millions of years ago, many have experienced numerous episodes of deformation and metamorphism which left them with few characteristics of their original form.

2. Classification and types of mineral deposits: Geologists classify mineral deposits in many different ways, according to the: • commodity being mined • tectonic setting in which the deposit occurs • geological setting of the mineral deposit • genetic model for the origin of the ore deposit

3. Finding ore deposits:Geologists are always searching for more ore deposits to meet constant demand.

4. Oxidised zones of ore deposits: The region above the water-table in an ore deposit is known as the oxidised zone as it is the zone of oxidation of the primary ore minerals. This oxidised zone is primarily composed of mixtures of iron oxides/hydroxides and quartz which we call gossan.
