Non-magnetic Concentrate

No appreciable levels of potentially valuable by-product minerals have been encountered in the silexite bulk sample from the Mt Everard workings. However, the minor amounts of certain mineral species present do report to the non-magnetic concentrate fraction as follows:

Element Metal or oxide reported in assay Assay in %
Bismuth Bi 6.45
Cerium CeO2 4.75
Lanthanum La2O3 1.56
Phosphorus P2O5 3.94
Tin Sn 0.60
Tungsten* WO3 3.13
* The tungsten content may reduce once magnetic separation is optimized.
