FIGURED IT OUT ?Have to considers a few more variables...
Lines on NCP's graphic Chart are representing
Years 6 - 10
Ore Stratigraphy places magnetites atop the serpentines.
As one mines the ore body....
Eventually the miner will encounter the serpentine
geology.
STRATEGRAPHY

1 - Select composite ores were chosen
Who chose these ores ?
2 - 1100 kg composite ores were sent to " Sudbury "
100 kg over the 1 metric tonne
3 - Bulk Concentrate is shown prior to entering extraction
What was performed prior to label it = bulk concentrate ?
Seen left side on image.

4 - Did the original 1100 kg have any wastes ores removed ?
Silica etc...?
5 - Even if, portion of waste ores were removed - grades of ore,
would remain same - right ?
6 - What would constitue a more than doubling of, Mg ?
should still be, 16.4% right ?
7 - other waste ores like ( silica ) removed = would be replaced with, Mg ?
Magnesium Nickel.
8 - Keep in mind this is a preconcentrate phase.
It would take the removing of over 16% silica inorder to
replace the 16% waste mass with over 16% Mg.
This would definitly - explain the more than double Mg values.
9 - Yet....what if....
solid solution Nickel were in the silicates ?
50/50%
Nickel found that in the serpentinized rock about
one - half of the total nickel occurs as visible native nickel-iron;
the rest apparently is in the silicate structure of the serpentine. In the
fresh olivine and pyroxene, all the nickel appears to be in the silicate.

Serpentine Nickel.... two kinds of nickel.
As i've mentioned before - solid solution Nickel
Green ColoredSilicates.
10 - Let's just assume the model of,
Silicates removed.
Replaced with.... Mg.
Bulk Concentrate now has....more than double the Mg.
More difficult than silicate Nickel.
11 - If there were any Nickel present in the Silicate would you
remove the silicate ?
If no Nickel in the silicate and replaced with Mg that has Nickel
Then.... would a 0.26% Nickel be seen in a bulk con or should
there be an ( increase % ) of all the more nickel ?
If original Mg percentages are 16.4% and supposing this is
where all the Nickel resides - then....
16.4% Mg = 0.26% Nickel
35% Mg = All the more Nickel right ?
What does the nickel ( reference head grade ) say ( nickel % )
0.31% grade
https://live.staticflickr.com/65535/53241269688_14fbe29879_z.jpg
Should'nt Nickel be....
over 0.52%+ grade due to a more than doubling Mg ?
12 - What about the other minerals too ?
Should not the Bulk Con have increased, Pd, Pt, Au, Co, Cu ?
13 - Here is the mineral grades in which was used by XSP.
Compare these 2 charts.

14 - As for the sulphur in former post ?
Maybe the 23.22% Sulphur is a recapture to use again ?
( cleaner con )
Open Thoughts...
Show me 1 Tonne ore
Tell me exactly what happened to the 1 Tonne to make Bulk Con.
If Mg is more than double and supposing this is where Nickel resides
Then...shoildn't nickel grade increase by more than double ?
If only 0.31% what was the purpose of, making the Bulk Con ?
0.26% original grade to 0.31% nickrl.
And more than double the Mg to deal with.
And if Mg is considered waste ores. ( they shouldn't be )
And if only 1/2 recoveries are achievable
Then....1/2 nickel would still be in the Mg ?
Whose getting the Mg ?
lol
And what if Silicate does contain nickel - no mention of
where the silica ends up ?
Iron credits
Silica nickel
Mg credit with potential nickel
If 50% extraction achieved
does this not match the 50% or so extraction achieved ?
Sounds like two concentrates ?
lol
I actually came across another nickel junior with
1/2 recovered nickel.
Same thought came to mind.
Waste ores are similar to extraction recoveries.
Near 50/50
Place this in the context of,
Concentrates do contain wastes ores...
Could waste ores be precieved as.... another concentrate ?
Ohhhhhhh.... the nickel markets.
