"FNQ engaged CDE Global Ltd (CDE) to undertake a sand classification study and produce a flowsheet for
processing the Sandbox ore and for the purpose of identifying its suitability and potential to be beneficiated to
make a Sellable Glass Grade product.
CDE are very experienced in materials handling and processing and have a high profile in the sand industry

The attrition process stage showed virtually no change in assay results except for TiO2 and Al2O3 which both
experienced modest reductions. The final processing stage tested was high intensity magnetic separation. In
this test the sized and attritioned float sand is passed over a dry magnetic separator at increasing intensities,
to see if iron bearing or magnetic minerals can be separated to improve silica grade.

Based on the testing results, 99.5% SiO2, 190ppm Fe2O3, 3100ppm Al2O3, achieved there is likely merit in
pursuing this resource as feed material for the production of glass. The resultant sand product is in accordance
with the specifications required for Float and Container Glass.

CDE then subjected the processed product to a Hot Acid Leach (HAL) process and was able to reduce the
Fe2O3 content to below 100ppm. The Al2O3 altered by a small amount and the SiO2 content was improved to
99.6%, sufficient for the Float Glass market."
