Ann: Quarterly Activities/Appendix 5B Cash Flow Report, page-27

Hi Chemist,
Thanks for raising this important question. I believe that you are doing due diligence.
I also found the below. So it looks like HAS has been onto this issue since at least 2017.
I now need to check on how my other REE miners are handling this issue.
Thanks for raising it.

“The Project will consist of a series of open cut mines, associated with discrete deposits, a common beneficiation facility and a hydrometallurgical processing facility. Tailings from the various processes will be directed to dedicated Tailings Storage Facilities (TSF’s).

The ore contains elevated naturally occurring uranium and thorium at reported average concentrations of 27ppm and 450ppm respectively. When combined, the total activity concentration of the ore is approximately 2Bq/g (heads of chain). The thorium concentration and the combined activity concentration of the ore meets the definition of a radioactive material (ARPANSA 2014). The majority of the radionuclides will report through to waste streams and be disposed in the TSFs.”
