Potential markets are being evaluated for the waste piles. It is believed that the material, upon crushing to a fine particle size, will have certain applications as an agricultural carrier, soil nutrient and sorbent for environmental remediation. The presence of ferrihydrite mixed with clays will have some use in remediation of contaminated sites, especially when mixed with halloysite, kaolinite and illite-smectite.

It is considered that the 4.5 million tons of waste pile material has an Inferred Resource status. Work is ongoing looking at potential markets.

  • Evaluation of clay fraction of five waste piles

For this study 185 samples were tested for their mineralogy by XRD and 133 samples for their chemistry by XRF. Clay was refined to <5 microns for all waste piles apart from WP3, which was processed to <45 microns. 500 tons of WP1 was wet processed at KaMin’s plant in Sandersville and some of this is being trialled by a potential customer at the present time with encouraging results. Given this encouragement WP1 is considered a Measured Resource with remaining waste piles an Indicated Resource status. There is a total of 757,880 tons of clay that can be processed from the five waste piles.
