maybe for you .. and others as well ... go to... https://ceo.ca/xmg .... read some of what 
"geomean" has to say about intersecting multiple acquifers ... 

I had started doing research on my own when I read about there being sinter involved 
in samples ... I feel much much better now after reviewing the information ... and that they 
have drilled through some of these more difficult mineral compositions ... 

I would go with 100% that there is lithium brine and lots of it , but I don't have a significant 
enough background ... the only other place I could find anywhere involving sinter is in 
Yellowstone where there are ancient underground mineral formations ...

when it is clear they have a path to the brine... it will then be known some of
the immense enormity of abudance of this find !!!
given some of these layers of minerals stated in the release it can now be seen as a 
massive ancient cave of brine minerals and more than likely to be lithium in high grades
note even discussed as of yet !!!

cheers !
