Thanks for the response, but based on the reactive Silica being approx 6% average and the high grade content of the AI, wouldn’t this high grade and extra Silica cancel each out, to an extent? From what I can see from other grades the reactive Silica is around 4% with a lower AI content (44%) For sale at approx USD35 per metric tonne.

If you lose USD5 per metric tonne based on the Silica content wouldn’t this put the price at around USD40 per metric tonne - could also be higher based on the price of Bauxite at the time.

Re mining, makes sense that this resource is purchased buy the BHP mine down the road considering the infrastructure etc that is already in place and being utilised by them.
