TERTIARY
70% of the kaolin produced from the Nyora kaolin deposit is used in the paper industry, mostly as coating clay. The remaining 30% is |
used in the paint and plastics industry. |
Two pits are currently operating (November 1999). The Winter's pit in ML 5685 and the Nyora pit in ML 50071. The Nyora pit kaolin |
has lower grit and higher brightness than the kaolin from Winter's pit, and is used as a filler grade. |
Nyora pit kaolin is overlain by silcrete, overlain by basalt. Here the kaolin is underlain by Tarong beds and coal. At Winter's pit the |
bedrock is sandstone with granite below. |
