NICKEL CARBONATES - calcite type symmetryAnd i ask,
How would a programmed spectrometry scope ever distinguish between a nickel calcium carbonate or nickel carbonate if... if... it's optical eye " might " have preprogrammed parameters
that only identify calcium crystal structures ?
Especially if,
carbonate nickel does exist and it has the same calcite type symmetry.
Driftwood, has the irons, chromium, titanium and nickel values.
But... in former " bulk test " reports some of the impurities were removed.
Which could suggest - these impurities could be rather important if oe was seeking a secondary
mineral credit over and above - magnesite.
Another important apsect are the calcium carbonate values in Driftwood,
There's the higher purity magnesite with a good 43% magnesium.
And... there are dolomites outside the core ore body.
Dolomites would harbor far more calcium percentages thus... increasing the " odds " of a potential
nickel carbonate.
Why nickel carbonate ?
In, the 2001 assay report -
nickel, chromium and titanium, all 3 minerals are related to - nickel.
If nickel was detected in 2001, though small values - it should trigger one to ask,
could other nickel values have converted to - carbonate with a a calicte, clacium carbonate bond ?

Others juniors in B.C. are finding nickel in magnesite depoists.
This is a good example that - nicke does run in magnesite and dolomites.
I decided to research the relationship of,
magnesium and calcium carbonates and thier relatioship to - nickel -
Yes... looking for hidden, multibond or undetectable nickel -

Very good read....
Do zero in on the subject of,
crystal structures
Summary. Nickel carbonate occurs in nature as a hexahydrate (hellyerite) and as a hydroxyhydrate (zaratite), but the anhydrous species is only known as an artificial product. All of the compounds show anomalous properties that have led to confusion in the literature.
Only the calcite structure was found for NiCO3 ; hydrothermal conditions appear to be essential for its synthesis, and a variation in cell size was found with changes in duration or temperature of synthesis, or both. Hellyerite probably is [Ni(H~O)61 CO3, which would explain its ease of decomposition and rarity in nature.
Zaratite is not a single mineral, but a composite of amorphous and fibrous components. The conditions under which NiCO3 might be expected to occur are discussed. Nickel bicarbonate formed in the reactions to produce NiCO3 ; its X-ray diffraction pattern, indicating cubic symmetry, analysis, and optical properties are given. The behaviour of nickel in these compounds is best explained in terms of crystal field theory.
the crystal structure is of the calcite type. A prominent exception is nickel, which, although NiCO3 has been made synthetically, has never been found as a natural mineral in the form of an anhydrous carbonate. Yet nickel is moderately abundant in the crust of the earth, and its ionic radius falls within the limits for a calcite~type carbonate.
Where nickel has been observed in association with calcite or dolomite, there are found distinct nickel minerals, which have a composition dependent upon the impurities in the host rock and the compositions of the solutions, rather than a solid solution of nickel in the carbonate.
A calcite containing 0.65% Ni has been reported (Maksimovi6 and Stupar, 1953) and also one conta;ining 0.83% Ni (Maksimovi6, 1952). The mineral, zeyringite, has been classed as a calcareous sinter (probably aragonite) containing nickel, but has recently been shown to be aragonite coloured by inclusions of aurichalcite (Meixner, 1962).

Again,
bulk samples years ago had impirities removed prior to - magnesite grade testing.
Cheers....
