PERIDOTITE Green Silcous Rocks
Serpentine, Olivine, Peridotite.
https://en.wikipedia.org/wiki/Peridotite
Many believe the green is attributed to, Nickel.
Peridotite is formulated with, silica, iron, magnesium, nickel
What's not spoken of ?
Chlorite rocks are also green which contain chloide.
What does Nickel chloride look like ?
Reading up on former assay methods on Wellgreen,
and seeing " partial digestion " and veering from " rhodium or 4 exotics
= not too swift.
Assaying is the means of which quantifies the true metal worth.
If by chance Wellgreen has significant peridotite olivine ores,
and if - Iron Nickel swapped with a chloride and silicate ( which ocean waters )
do contain silica in salt water then...
Most probable end outcome ?
Nickel in solid soultion - bound in silica hard rock ( olivine, peridotite.
= Green colored rock.
EXAMPLE
Junior just spent millions drilling
Happy, excited to find out what their grades are
Sends peridotite core samples to assay lab
4 PART ACID DIGESTION - aqua regia
A four-acid digestion utilises a combination of nitric, perchloric,
and hydrofluoric acids with a final dissolution stage using hydrochloric acid.
When combined with a pXRF analyses to determine Si
(not reported by four acid) and other elements not fully recovered

Peaple actually eat and drink - silica. ( health suppliments )
Even present in oceans and great lakes.
Can nickel bond to silica ?
key silicate species generated from the ablation plasma that reacted with the
nickel cations to Ni-PS was silicic acid
Reread - 4 part acid and if silica values are reported ?
Silica not reported.
What if nickel is still in a potential - silica bond ? ( silicic acid )
Let's scope other acids used in 4 part acid digestion.
If you dissolve solid nickel chloride hexahydrate in acqueous HCl you'll obtain a solution of nickel chloride......... at most, some Ni2+ could hydrolise but its pKa is about 10, so in an HCl solution nothing would happen. How are hydrochloric acid and nickel related? HCl and Ni are not related in any way.

Having conducted an investigation involving multiple metals, I have found that nickel refuses to react with concentrated hydrochloric acid.

Others report this...
Nickel react with hydrogen chloride to produce nickel(II) chloride and hydrogen. Hydrogen chloride - diluted solution. This reaction takes place slowly. Nickel(II) chloride is produced by dissolving nickel or its oxide in hydrochloric acid.
Note - most likely nickel made into metal then reacted.
Big Diff when it comes to raw mineral ores already in other bonds.
As mentioned prior...
I've read a paper on, nickel chloride single bonds are difficult for optical
spectromtry machines to detect. Involving - light refoection and ability of machine.
Minerals disolved in DARKER acids are better read by the spectrometry light.
I've addressed this on other bullboards,,
When it comes to nickel silicates, nickel olivines, one should take
extra measures asking for the best assay method inwhich to include all
nickel values ( solid solution + chloride + oxide + sulphide )
So what would happen in a partial digestion ?
Partial results ( lol )
Add in nickel single chloride and perhaps nickel silicic acids bonds
= could go undetected
I would veer from ( hydrochloride, perichloride, hydrofluric )
If using spectrometry.
Nickel attached to a chloride ?
Australian Nuclear Science and Technology Organisation
Cl is not a cation and therefore one cannot analyse it using ICP-OES or ICP-MS.
By far the best method is ion chromatography
which can measure anions as well as cations.
As one can read,
chlorides can be - problematic.
if nickel silicate were ever a nickel chloride at Wellgreen,
one should use several assay methods and find the best
inwhich to test the - grades.
Hence - i wanted to know what hudson Bay used given their stellar grades.
Let's ask....
how does nickel become a metal product ?
- Furnace melt
- Electrolysis
Therefore... these two methods are best.
If peridotite nickel at wellgreen were in chloride bonds...
I'd dissolve in chloric acid and apply electrolysis.
= Precision accuracy.
Majors know all about olivine nickel.
wink
As for CO2 Seq ?
Ever wonder why many PEA PFS have not provided monetized values
and omitted these payable credits ?
- Co2 per tonne credit $$$$$ adds more profit makes project more valuble
- Juniors never mention what will happen to the magnesium oxide turned carbonate.
lol
Mega bucks using the MgCO3 as magnesium cements.
$$$$$$$$$$$$$$$$$ ( can't put those figures in a PFS )
the value of the deposit would rise - lol

And just so happens,
Strategic Metals who once owned - Wellgreen and has land aside of
Wellgreen - lol - is into CO2 sequestration.
Cheers....
