South Africa has a very long 'earth
history' Many of the Rocks have
yielded rich in mineral deposits
and unique discoveries of Early Life.
Minerals are the building blocks of the
different types of rocks. There are about
3000 different types of minerals and they
are very important to us as they are used
to make things we use everyday.
South Africa has a large wealth in
minerals. Our minerals contribute to a
large portion of our revenue.
