Ann: Clay Hosted Rare Earths Discovered At Surface, page-24

of the announced results, the thickness, depth and grade therein puts it in the possibility of being economic.

I haven't looked into how widespread they are so as to estimate a potential resource but you usually will need 100-200mT so have a look there.

the prospective ionic clay project, like most, will live and die on the determination as to how much is ionic/colloidal. integral to understanding of its economical will be the met work. leach tests for extractibility rate need to be performed at ph3/4 and then ph1-2. acid consumption rates need to be called out in those.

if you can recover a decent percentage under sighter test work using neutral or low ph without an excessive acid consumption rate it begins to look economic. if the deposit has little ionic or colloidal REO's present then it's curtains.

I'll continue to watch and wait for met work but decent results based on what's known so far. more than others can say.
