I'd like comments on the geology of Halloysite-Kaolin initially.

Is it always found at shallow levels ?

Please don't tell me how to make ceramics.

I just need a heads up on how to read announcements. Is shallow good or bad or maybe for deeper or just wider for starters.

This is also not a geography thread, nor perils of China, nor etc. I use duckduckgo for that.

How is a punter to read announcements as one would read announcements from a Golder.

Oblique to your specific questions but I was considering MEP and ADN just yesterday for their 25-75% Kaolin-Hallyosite jv in S.A. I thought this interview with the M.D of ADN easy watching and good value. I had no idea of its applications beyond porcelain (e.g electrical properties). I probably won't be buying either unless they tank a lot further.

Thanks @finicky .

Unfortunately this doesn't seem to answer my question.

When a Kaoliner hits shallow Hallyosite-Kaolin is it then looking wider in area to confirm a big find, that is laterally and anterior/posterior in 2 dimensions or does it need deeper deposits. I cannot find any answer to this and I only know Gold.

I've had a look at a few of these and concluded that if all the HPA Halloysite/ Kaolin deposits in WA were exploited, then it would be best to short the grain handlers, because there wouldn't be much wheat /sheep acreage left untouched.

That doesn't answer your question, I acknowledge, but it does seem to be widespread, diffuse and shallow. Weathering is a surface event. Sometimes the mineral will collect as a deposit and then be buried ...
Kaolin is a rock rich in kaolinite Al2Si2O5(OH)4 . Kaolinite clay occurs in abundance in soils that have formed from the chemical weathering of rocks. It is a layered silicate mineral.
Halloysite has the same chemical composition as kaolinite; Al2Si2O5(OH)4 . Halloysite naturally occurs as small cylinders (nanotubes); the outer surface is mostly composed of SiO2 and the inner surface of Al2O3, and hence those surfaces are oppositely charged.
HPA is a high-grade form of non-metallurgical alumina, with a purity level of 99.99% or above. The material is chemically inert in most environments, has a very high melting point, and does not conduct electricity.
Traditionally, bauxite has been used as feedstock for creating a refined aluminium metal, which is then processed further to create HPA. However, this costly and energy intensive method of manufacturing HPA has restricted its production. However, technological advancements have spawned several disruptive processes for producing HPA directly from other sources including kaolin or its purer, less common derivative halloysite, and industrial feedstock. Most of these newer processes bypass the aluminium metal stage
 
Thanks @Dona Ferentes

My impression is that it is a shallow mineral, a clay really, and it needs large areas for shallow open cut mining.

This will then involve for muppets such as I with a 2:1 and not a 1 in the classics to stop scribbling and burrow further.

The Kaoliner announcements are becoming clearer but still covered in other minerals and detritus for me.

In a nutshell:
Geology will be either primary or secondary. That is, either broken down in situ over time, or washed away to another site.
Buyer demand is based principally on brightness, level of impurities and particle size.
In situ deposits usually meet first two criteria, and secondary deposits provide finer particles, for obvious reasons.

From a mining perspective obviously the shallower the better (strip ratio factor), and the more the merrier.
The Wickepin deposit is a cracker!

My intention is in no way to highjack this thread but I found this site and wonder how accurate it might be, as a tool to quickly interpret drilling announcements.


All the best

Geological background here.

Drilling will tell you the extent (inc. total volume) of kaolin and quality. But the nature of finds is not difficult to decipher as it's a bit like mining coal (in that you mostly pull out coal).
 
May be of interest Mr @Garpal Gumnut ?

ASX Announcement
1 September 2021
EXCEPTIONAL HIGH GRADE HALLOYSITE
DISCOVERED AT GIBRALTAR HALLOYSITE PROJECT
HIGHLIGHTS:

 Exceptional high grade halloysite and kaolinite results returned from large zone of
bright and ultra-bright white kaolinite in drilling by Oar,

generating highest grade halloysite observed in any project in Australia:

o Highest grade composite sample of 53% halloysite
o Multiple composite samples grading in excess of 30%

 Results far exceed Oar expectations, and confirm discovery of a premium-grade
halloysite material with expected significant growing demand by global off-takers seeking supply of high grade halloysite for its nanotube properties

 Halloysite results from the southwest target area, which stretches over an area of
2.5km X 5.0km (defined by +70 ISO-B), have confirmed multiple coincident halloysite anomalies defined by +10% halloysite

 Three additional “Bullseye” anomalies with coincident high grade halloysite and high brightness kaolin also identified, demonstrating strong potential to define a large inventory of high-grade kaolin-halloysite at Gibraltar

 Systematic drill testing of the high-priority southwest target area and three bullseye targets to be undertaken under the Company’s existing drilling permits

 Next drilling already contracted, and expected to commence in early Q4

...another S3 promoted stock? These guys are unstoppable.....

Whats the point in trying to figure out juniors anymore? Just follow the S3 ones.

WAK is 82 ISO... So is +70 any good?
