GOLD REEF

A small sample of quartz 'reef'
from a gold mine


2.9 billion years old

Witwatersrand,
Johannesburg, South Africa


In the world of mining, the word 'reef' is used to describe an ancient sedimentary rock consisting mostly of quartz fragments and containing a relatively high concentration of gold.  Quartz reefs in South Africa account for nearly 50% of all the gold ever mined on Earth.  

This item is from an old collection and was obtained from the mine several decades ago. It is a typical example of a gold reef, obtained from a great depth underground.

The gold, which is in the form of minute particles, is not uniformly distributed throughout these reefs and therefore there is no guarantee that an individual piece contains any gold.  Golden pyrite crystals are, however, present.
