The Directors of Stellar Resources (ASX: SRZ, “Stellar” or the “Company”) are pleased to advise that a second round of ore sorting test work was successfully completed using slightly different technology and recently acquired diamond drill core samples from the Severn tin deposit.
200 samples of ¼ core ranging from highly mineralised to waste rock were processed using Steinert KSS technology (see Figure 1). The results show that the technology works well with Severn mineralisation and can achieve significant waste rejection and increased head grade with only moderate tin losses. Optimisation of the process using a larger sample would verify the results and potentially generate an improved outcome.
Managing Director Peter Blight said:
“Ore sorting technology is being implemented in older tin mines such as San Raphael in Peru and Renison in Tasmania. This validation of the technology is positive for Stellar’s Heemskirk Tin which is focused on opportunities to reduce unit cost. The technology can also provide savings in processing capital and reagent use which will be investigated following optimisation of the process using a large sample.”
