| Mining & The
Resource |
| |
| The sand at Sunstate's
Coonarr Creek, Bundaberg mine is pure white, high
grade silica sand of about 99.8% silicon dioxide.
The Sunstate Sands resource is unusual in that
it can deliver material from below 250 microns
up to 5mm.
The company has graded the resource
into three major products. These in fact occur
as layers upon each other commencing with the
superfine at the top and finishing with very coarse
material at or below the water table.
The resource varies from mining
lease to mining lease and within each lease, analysis
has shown the resource can be broadly identified
into.

| The Production
Process |
| |
| Raw material
is extracted from the selected mine area, processed
through a wet plant, stored, then selectively
processed through a drying plant, then supplied
either in bulk tankers, bulk tippers, bulk bagged
or 20kg bagged on pallets. |
| |
| |
| |
| |
| The Wet Plant |
| |
| The raw material
is transported direct from the mine and loaded
into hoppers, which feed the wet plant. The purpose
of the wet plant is to remove all foreign debris,
and produce an initial cut into the following
sizes. |

| |
| The Dry Plant |
| |
| The sand is
shifted from the wet storage to the dry plant.
It then passes through a rotary dryer and then
across various screens and then sized to produce
the range of product to meet individual customer
specifications. |
