OK I'm going out on a limb here but this is what I am reading into this Halloysite grade Ann.

The minus 45 micron sample is split via centrifuge into

[ note : It is commonly assumed that -45 micron is predominately the Kaolin ( most of sand removed) ]

-2 micron and
2 to 45 micron samples

The particle size distribution { PSD } of -2 micron is approx 68%

Thrn taking the Ave Halloysite grade of 59% in the -2 micron fraction

would translate to a grade of approx 40% in the -45 micron fraction ??? assuming as well that there is no sample loss of Halloysite in the seperated -2 to 45 micron

Keeping in mind that

The current JORC resource has Halloysite calculated in the -45 micron fraction and we are looking at 18% .. already way above Ave

are we looking at bonanza Halloysite grades ?

Happy to be corrected
