Halloysite, Halloysite and Halloysite!!, page-643

Nice pick, Wayne.

Here's a quote from an old SPglobal.com article:

Belperio said researchers were excited by the prospect of what they could do with millions of tonnes of nanotubes available from the halloysite in the ground in South Australia, particularly given it is of superior quality to artificial carbon nanotubes, and Marsh said Andromeda has "all the significant known halloysite tied up."

Though there are other juniors in South Australia that claim to have halloysite and others with North American projects that have struggled, Marsh said retired Geological Survey of South Australia chief geologist John Keeling, who has published much work on halloysite, verified Andromeda has the "only genuine halloysite that he's aware of in South Australia."

Also Interesting to see Dragon have such a big surface area increase - I had them down as an also ran / wannabee, but that on the face of it is an interesting surface area increase. I will read the whole paper now - thanks for posting.
