Halloysite, Halloysite and Halloysite!!, page-362

There is a conference call from last year where a process for separating the Halloysite was described.

Multiple shareholders took notes.

• To purify Halloysite
  • particle-size cut (2 micron)
  • centrifuge (standard kaolin industry equipment)
  • for small samples achieved 92% Halloysite
  • for large scale - a large centrifuge

• Of interest to me was the -2um particle cut potential with centrifuge bolt-on to the wet processing plant to allow for preparation of up the 85-90% high purity halloysite (HPH).

Furthermore from the last quarterly they are designing the plant so they can integrate upgrades for product variations. I think this means essentially making allowances in the location of equipment and I guess future interconnection of other equipment they could use for adding upgrades later. Initially I think they are thinking plant upgrades later for the Paints & Coatings applications and the Concrete Rheology Modifier.

They have other studies in background that will feed separate feasibility studies for the Paints & Coatings applications and the Concrete Rheology Modifier.

For paints & coatings they would be using the part of the resource that is low Halloysite content.
