2015 PEA was based on -
Gabbs, Clino, Sulphides Chart below ( colored highlights added )
- Chart 1 actual resource
- Chart 2 - only mineralized tonnage
Main Focus ? Waste Ores -
let's play suppose. Several reports state peridotite encompasses the gabbs, clino, sulphides
Peridotite was not the focus for 2015 PEA
16 Yr mine life = Gabbs, Clino, Sulphides
8 / 9 Yrs = Peridotite stockpiles ( ( 1 - 10% ) that tagged along.
= 25 Yrs...
Could.... one could assume much of the waste ore is still peridotite ?
No other diff ore is mentioned outside the, gabbs, clino, sulph, dunite, serps, olivine.
Drill holes took on a different persona after 2012,
Upper + Lower come into play
Gabbs Sulphide, Clino
vs
Peridotite
2017 - press - majority ores are Peridotite.
In Johnson's drill hole image it provides a superb breakdown
of minerals in upper vs lower hole.
Peridotites hold their own....
just as good as lower intercepts.
Some reports state the Peridotites have significant plat metals
along with, Cu, Ni, Co.
Hypothetical - assuming waste is Peridotite
296,200,000 million tonnes ( waste ores )
x 80% ( my own reduction to eliminate other waste ore )
= 236,960,000 tonnes
x .26% Ni ( just nickel....i could also use an Eq )
= 616,096 Ni tonnes
x ( GT or Industry standard 55% recovery )
= 338852.8 Ni tonnes
x 2200 ( convert to lbs )
= 745,476,160 ( 3/4 billion pounds ) Ni
+ 1,700,000,000 billion pounds Ni ( Gabbs, clino,, sulphides ) 2015
= 2,445,476,160 total payable Ni metal
This junior has made peridotite an issue.
When GT met studies had no issue.
Why do a retake with xps when they used a course grind vs GT's fine grind ?
No of this nonsense is seen in, Timmins other than,
only extract ( skim ) half the resource.
Pardon the pun....wink.
Again,
If 2015 has a yearly 68 million lbs of Nickel payables x 25 yrs
= 1,700,000,000 billion Ni lbs ( this is factual payable Ni metals 2015 pea )
2023 has more tonnage
less payable nickel
624 million lbs Ni
Hence....
what the heck happened from, 2015 to 2023.
My beef is...
Other juniors have good extraction recoveries with,
dunite, serpentine, peridotite using XPS
Other juniors include an iron credit
NCP doesn't
We have plat exotics...
Not even accounted for.
Heck...
our iron + plats are higher grade than, timmins.

Great Read on Wellgreen - Skarn = Lime Carbonates
Massive sulphide lenses along the gabbro-
quartzite contact give way below this structure to mixed gabbro-skarn zones
containing erratic sulphide veins and segregations. The highest PGE grades
with respect to copper and nickel values from the 1987 reanalysis of available
underground drill core were obtained from this type of material. For example,
a reanalysis of remaining core from Hole U432 returned values o f 1.52% copper,
1.03% nickel, 0.056 oz/ton platinum and 0.053 oz/ton palladium over a true
width of 10.6 m.

When i was reading 2015 pea....
couldn't help but notice a few pages outlined Quill zone.
I said to myself.... i never saw that before...lol
Date...on image from eng firm said, 2012.
lol
Here's a corp fact sheet page from, 2016
Main wellgreen runs into the new quill.
Why am i hung up on this ?
because defining a resource constraint to just main, central, far east
could chop considerable tonnage off...if the deposit down plunges
into the quill.
If i get around to it...
I'll reposition Johnson's holes - overlayed on new pit.
Put it this way....
If Johnson's holes are where the 2015 pea states...
Why the hell is out pit only 120m ?
Throw in 300m - 547m drill depths inside mine.
Where is the true tonnage under mine ?
Johnson's hole would provide an incredible stepout.
Lots more tonnage.
Cheers....
