Hi
@ocka
It is both the high grade lithium content and the type of mineralisation identified in the samples.
I tried to explain this on my post #:

When we look at the anns released back on Jan.31 2018 "
Morabisi Final Analyses For Turesi Have Now Been Received"
we can see on the tables that they have found a lots spodumene in the grab samples.
Spodumene is the mineralization which has very high lithium content. So it is the most valuable economic type mineralisation.
Spodumene is not a concentrated form of mineralisation by outer effects, it can not be concentrated like lithium brines or clays (hectorite) but it speak for itself in terms of L2O content as it has a crystal structure and it is insoluble in water. However it could be weathered by acidic rain water of course.
So when you find spodumene it is an exact sample of mineralization which is evolved in a long time inside the rocks. You can get better grades by drilling inside the rocks.
Here is my old post;

we can see on the tables that they have found a lots spodumene in the grab samples.
And it was high grade and wide spread; "A total of
244 grab samples from Turesi have been collected of which 77 analysed greater than +1% Li2O and 14 greater than +2% Li2O."
See the assay result tables below.
Spodumene everywhere.
The assays were made and the report was prepared by a lab in canada.
It reports a lots of pegmatite, spodumene, spodumene in veins (which is now mentioned as "Pegmatite stringers" in GPP's anns.)
Where did so much spodumene came to that location?
First of all finding spodumene is showing that geologically the right conditions have had happened at the location, especially under the ground. Otherwise it is not possible a spodumene mineral cam to there from the sky.
You can find only lithium mineral in the clays, that could have been transported by the aquifers through the rocks and could be accumulated there. This is the characteristic of brine and even clay (hectorite) deposits.
However spodumene crystals won't be transported by the aquifers or by the other factors. They have to be part of the pegmatite system under the ground.
Also, lithium as a mineral could be concentrated on the surface after being transported by other factors, but spodumene is a crystal form of mineral, it wouldn't concentrate in anywhere other than in a pegmatite. This is what was said to me by a few geologists, I mean I got that confirmed by a few experts.
What I trying to say is; the spodumene in the Turesi belongs to the pegmatites in Turesi. Where are they then?
That's what this drilling campaign is trying to find. One of them has been already found (26m pegmatite) IMO. We will see the rest.
I believe that the pegmatites GPP will found under the ground should have high grade lithium in spodumene, polylithionite and other forms in my opinion. I am waiting patiently for the results.
