Purple potassic rocks redoxing to
Green.
Heavy green bloom.
Follow Bluffs near Ivana - head south westerly along rim of bluffs.

The purple coloured potassium permanganate reacts with KOH to form green coloured potassium manganate. ( manganese )
Potassium permanganate is purple in colour.
On adding KOH, it turns green. Argentina type uranium - phosphate, potassium, coffinite - redox tertiary
BSK furthest extension ( Baja )
Is aside of massive Mountain ( most likely former volcano that errupted - broken rocks )
Watershed ( massive ) moved the small broken rocks ( green, purple ) towards Picos.
Theory.
What attracts me most about 12 km target ? These putple rocks are reactive with watershed also ( sm river at rim of bluff )
vs
Chihuidos purple rock bluffs have not changed to green
Chihuidos only manganese ?
Or... potassic shale rocks ?
What i like about S America... Phosphates and Potassium have higher % of uranium content vs other world regions.
Though... still low grade - rocks at surface can off set costs.
Keep in mind, organics, wood, vegatation, algae have a high affinity to absorbing uranium.
Besides volcano blowing out sm rocks, there is natural veining assoc to purple rocks.
And since i'm only seeing tops 70m bluff depths ( transition ) i can't dismiss
reef typology. Macro scale - lots of open arrid flat lands similar to long ago ocean floor.
All surface rocks with larger rock formations throughout.
Being at surface - crushing milling costs wouldn't be that high ?
Argentine peso vs cad is very favorable.
If Argentine's work for 200 or so pesos per hour....( wage )
200 pesos = $ 0.28 cents Canadian.
I'd be testing this 12 km target asap.
See if it harbors elevated uranium values.
Cheers....
