Good pickup, did find it odd they used 2um when they've always used 45um

Does seem to be a correlation when you compare drillholes (consistently higher halloysite % in the finer particles).

2um % vs 45um% results for each drillhole

cw5 29% vs 6%
cw7 66% vs 20%
cw8 24% vs 9%

tw1 60-65% vs 23%
tw5 45-49% vs 8%

te1 52-63% vs 28%
te3 76% vs 28%

cd1 62% vs 10%
cd5 55-91% vs 27%

average 59% vs 18% (careys well)

Certainly not a bad announcement (speculating - easy to purify at 2um?, higher % at Condooringie is why they are smashing the drilling there?).
But maybe not as exciting as I thought on reading 59%* halloysite this morning (but I could be talking rubbish, I'm still not sure?).
