OLIVINE NICKEL + CO2 = HIGH NICKEL RECOVERIES Let's divide the wellgreen ores into two geological domains
Lets deal with high grade gabbro extraction at aclater date
Let's just place the focus on, problematic silicate nickel
Let's cancel ( 86% ) of the inferred.
Let's avoid an iron credit.
Let's not include exotics.
Let's change the boundary zones - squeeze out drill holes.
Let's get rid of Johnson.... he's just too good.
Let's use an extraction that applies Practical Entitlement
Let's create well over 500 million tonnes of waste ores
Let's reduce the resource a further 100 million tonnes ( pfs )
Or.... one could read this extraction paper.
Converting, Olivine, Clinopyroxine etc... to carbonates.
Then leach with Nitric Acid.
High metal recoveries.
Typical Acids with fresh olivine Nickel,
" For fresh olivine these values are only 66% and 64%, respectively. "
Or, use the Carbonic Acid approach.
Convert the silicate Olivines to carbonate, then acid leach.
Excerpt -
This impact was even more apparent for the leaching of carbonated olivine with HCl and HNO3, where Mg, Fe, and Ni extractions increased from below 10% at 0.02 N to nearly 100% at 2.56 N. Most notably, the leaching of nickel from carbonated olivine is substantially better than from fresh olivine when using hydrochloric and nitric acids. A concentration of 2.56 N of either acid leaches, respectively, 100% and 91% of nickel from carbonated olivine.
Selective metal recovery of the olivine during carbonation might substantially enhance the leaching and reduce extractant consumption. During carbonation, the metals dissolve due to the acidic aqueous solution as a result of carbonic acid formation. The residual solids could then be separated at high temperatures and pressures prior to exiting the reactor, producing a purified silica stream and a concentrated metal liquor or metal precipitate.
Another option is to separate the final products (i.e., silica-rich clusters, carbonate crystals, and metallic particles) prior to leaching, and leach only the metal-rich fraction; this may reduce the amount of sequestered CO2 liberation. Lastly, re-use of any CO2 released during acidification can contribute to lowering processing costs associated with CO2 concentration from industrial emission sources. These processes are presently in development using the proprietary reactor technology of Innovation Concepts B.V. called the “CO2 Energy Reactor”

What promoted me to seek out this extraction model ?
Over the years i've come across " nickel carbonate " minerals.
Wellgreen has a good visual of carbonate presence ( topically ).
It's been on my mind the past few weeks ( wondering ) why no
reports have spoken of, Nickel carbonate, Mg carbonate, Fe Carbonate ( siderite )
Lot's of transition metals at Wellgreen, not once is carbonate minerals
spoken of, other than, calcium.
Surely, there must be nickel carbonates ?
Or...have oxides only been measured ?
I'd say this carbonation extraction is a,
Superb Find.
Image using such an extraction on, Wellgreen ?
All ores come into play.
Wink.
We could always petition, and ask the same for, Timmins nickel juniors
to erase their iron credits, erase 86% of their inferred, slap practical
entitlement on the remaining and if that's still not enough, take another
100 million ore tonnes off the total resource size.
Former post ( Johnson drill holes.
Is a guesstimate based on geology folations since there were no, GPS
coordinates in press.
Using this topo map with eastern FE boundary line.

Drills on Far East drilling into Quill.
Brilliant, squeezing in extra zone which reduced size of wellgreen east which
reduces extra tonnage + minerals for wellgreens - 2023 resource.

If i'm correct, it means,
Johnson holes are not included in resource.
If Johnsons holes are anywhere inside the FE....
Still not good.
Why ?
I measured the pfs conceptual pit depth in FE zone.
They used 10m benches.
Inside the mine mineralization goes - 545m below.
Johnson's holes upto 756m
Pit depth in Far East zone = 120m.
Our resources go much further down.
Our junior + extraction co - are allergic to, silicate nickel.
Too bad Wellgreen wasn't located in, Timmins.
( tease )
I've modified the pit image showing a few drill holes and
depth of pit vs actual drill depths.
Quite shocking.
Let me know if you want to see it.
Cheers.
