LAST ANALYSIS LET'S SUPPOSE IT IS - ( schist, chard pyrite, mica - or some sort of species of pyrite )
that is leaching = PINK + GREEN
And if... the other report i posted - nickel in " solution " was not detectable by, XRF,
And if... Nickel in solution is intolerable to - high heat - assaying - anything over 100 degree C.
And if... Nickel can come in several species of - pyrites -
And if... Nickel is now identified as a new species in - serprentine + chlorite ( former posts )
Then... Let's then see how other's labelled the Scadding ores...
PAGE - 13 - of the 622 page PDF - Mineralization on the Scadding mine site seems for the most part, to be confined to the
chloritic matrix in the unit logged as chlorite breccia. Fragments within the
chlorite breccia are composed of quartzite from the
Serpent formation. Gold grades are often greater when there is
pyrite present in the chloritic matrix. Visible gold has been observed in core in areas with
significant sulphide mineralization. It has been suggested that the gold mineralization is mesothermal in character and can be classified with quartz-carbonate vein subtype of gold mineralization, although and
IOCG style of mineralization has also been proposed. The breccias likely acted as both mechanical and chemical traps for the hydrothermal fluids.
The transition from green to pink rocks is likely to represent a redox boundary which envelopes volumes of higher sulphide and gold content.
Gold mineralization is hosted within the chlorite/sulphide rich central part of the zone. Chloritic wallrocks tend to be coarse,
dark green coloured breccia containing 70% chlorite and generally greater than 5% sulphide. IF I COULD OPENLY COMMENT - 1 - The mineralization whether gold or other, is associated to - irons, and pyrites.
2 - Breccia is too loose of a term. ( specific geology is needed )
3 - Breccia is obviously a fractured rock - but what kind.
4 - in my opinion it's not a redox, it's two minerals leaching - green + pink - in solution
5 - the schist or charred pyrite and other pyrites need accurate identification
6 - there is pyrite and iron in the breccia
7 - there is green + pink solution colors.
8 - 5 % sulphides in the breccia / other report - chlorite acted like iron in survey -
9 - if water, salt, calcium are present - it would coach / leach out other minerals into solution
10 - breccia - fractured rocks would have that space and allottment to allow causticfluids in.
11 - IRONS - PYRITES - GOLD - and i would make that bet... copper, cobalt, nickel.
12 - Just piss poor assaying.
NOW LOOK AT THIS PHOTO AGAIN... - Heavy green solution right in the schist or pyrites that look chard.
- Green solution gradually lightesd away from source - charrded pyrite or schist.
- Pink - same thing... the heavy pink color is eminating from the chard schist or pyrite
- Pink fases to lighter as it is away from it's source.
- Even the dark flecks and specs are some sort of schist / mica, purite ( chard )
- they too contribute to the pinks and greens.
Could it be chlorite ?
Could very well be... but with iron presence and no other minerals - we would see dark borwn and rusty colors... In my opinion, it appears as if other minerals are with in the - mica schist, hiding, and came in contact of something caustic like lime - leached out - and their colors are now seen.
Again... there's been a new species of nickel found.
In serpentines and chlorite.
Now ask... why do gem stone have so many names ?
I'm leaning heavily in the direction of, all gem stones and colorations are a causative from, minerals going into solution -
GOOD TEST -
weigh cores with heavy green colorization with other cores that are with diff colors.
If the heavily colored green cores weigh more.. .it could point to - minerals in solution, accounting for the extra wegiht. They won't be as heavy as, actual metal species, but evenstill...
I'd like to see how an XRF detection reacts to the - schist mica pyrite - and colored solutions.
In the one report that studied nickel in solution - they said - it went undetected.
Giving a project a fair shake.
Looking for all minerals.
With diff assaying methods - is good to do.
And... veering from the carbonate quartz - since - Sudbury Mines - have nickel, copper, gold, cobalt, in the various multi species of - pyrites from irons.
There... i'll leave it at that.
