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:
* The tungsten content may reduce once magnetic separation is optimized.
||Metal or oxide reported in assay
||Assay in %
