IVANA ROCKS Here's a 2012 downhole image of Ivana's strata.
only 2 m ( but lots happening in photo )
no basement seen ( other ivana intercepts are much deeper )
gravel rock strata highest grades 2.74 % U ( proof gravel rocks = high grade ) V = 0.74 %
open in new window expand - 2012
Takeaways ?
First thing that comes to mind ?
Porosity.
Watery green concentrated silts ----------> seeping in from watershed / picos
Water also reacting with decayed hardrock ( suspended feldspar shelf ) no basement
Water ceeating carnotite
Water affecting existing loose rocks
Lots of loose rocks with green and purple / mauve colors
Loose rocks well over 100 um micron. Big rocks.
PEA only washes rocks and captures residues under 100 um micron.
Human hair is 70 micron.
PEA stock piles rocks for several years..... then back fill into open pits.
Or.... will they be milled - loose rocks and decayed shaley strata ?
Article from 2022 - same mine model as 2024
In the proposed setup, a simple wet scrubbing and screening process would wash away about 75% of the mass of an aggregate sample, leaving behind a concentrated mixture of uranium and vanadium. Alkaline leaching of the feed concentrate leads to projected overall process recoveries of 85% for uranium and 53% for vanadium.
Another version - 2019
The Ivana operation will consist of surface mining operation delivering mill feed to a nearby processing plant or stockpiles. The annual mining rate will be approximately 4.7 Mtpa (13,000 tpd) consisting of waste material and mill feed. The surface mine will be relatively shallow, with a maximum depth of 30 metres. The length of the mine will be approximately 3000 metres with widths ranging from 100 to 400 metres. The materials mined are unconsolidated gravels and sands and are free digging, therefore drill and blast operations will not be required.
Waste materials will be placed out of pit for the first few years. Waste will then be placed either into external dumps or used as in-pit backfill.
Feed material will first be processed through the leach feed preparation plant, a semi-mobile screening and scrubbing facility located at the proposed mining site. The leach feed preparation plant will liberate fine material (<100 µm) from the larger particles (>100 µm) and scrub away and recover fine uranium and vanadium mineral particles coating the large particles, into a leach feed slurry. The rejected coarse fraction (approx. 75% of the mill feed mass from which most of the original uranium and vanadium has been stripped) will be dewatered, stockpiled, and backhauled by the mine fleet to the dump sites or backfilled into the mine excavation.

What's so intruiging is....
Ivana is a U shaped deposit - same laydown as Picos watershed tail
BSK admits the Ivana extends beyond 1 km NE with upto 20 m depths
And.... Maria 1.5 km SW of Ivana has high grade pits. -----------> 69 pits were dug.
https://blueskyuranium.com/news-releases/trenching-completed-at-blue-skys-ivana-project/
Ivana's interior of U shaped deposit is granite hardrock - hump at surface.
1st Map
From Maria's pits to Ivana's NE constraint = 3 km
From Ivana's NW to SE = 3 km
Ivana's interior hump middle U shape fills the gap
3000 m x 3000 m x 2 m deep x 2.1 ore weight x .15% grade
= 56,700 t U ( estimate only 2 m ) even though bsk mentions 30 m deep
What so special about this number - 57, 700 tonne U ?
And 0.15% U grade ?
On March 13, 2012,
the Company announced preliminary results including a high grade pit
(1.40% U3O8 over 1.10 m including 2.74% U3O8 over 0.5 m – see Table below) that occurs within an interpreted paleochannel in areas of very high surface radiometric anomalies (+200 counts per second using a Georadis RS 125 scintillometer) that cover a large area of approximately 3 km2
The mineralization style and geological
setting at Ivana are similar to BHP Billiton's Yeelirrie uranium deposit in Western Australia*. Ivana, as with Yeelirrie, are both surficial uranium deposits that are situated in a paleo-channel directly overlying granitic basement rocks.
Pit From To Thickness meters % U3O8
I CAL 11- 35 0.00 1.13 1.13 0.20
I CAL 11- 36 1.10 1.82 0.72 0.11
I CAL 11- 37 0.62 1.72 1.10 1.40
I CAL 11- 38 0.48 1.37 0.99 0.43
* World Nuclear Association web site presents a resource estimate of 52,500 tonnes of contained U3O8 (174 million lbs.) at 0.15% U3O8 average grade in the Indicated category.

Why did i estimate 3000 m x 3000 m ?
Look above -------> 3 km 2 ( squared )
This would include Ivana's center hardrock - ha !
Grade avg of 0.15% % ?
Read the world nuclear caption.

POROSITY -
Seeing such dark green silts seep into the strata sands
Perhaps 2 water holes in strata with lots of decay in hardrock = easy water access
Very close to Picos
Ivana overlays Picos watershed tail exit
= Salar silt sediment concentrates seeping out entering Ivana ?
And annual watershed erroding hardrock and larger rocks - far larger than 100 um
More like several cm sized ( green and purple )
Again,
look at first image
where are the highest cps readings ( red line ) ?
Bingo ----------> gravels and dark green silts
Red Cloud's David Talbot is to interview BSK.
Dave just gave a rating for ------> Global Atomic ( uranium peer )
Look at what Dave earmarked Global Atomic's future price.
https://pbs.twimg.com/media/Gbe1Z7ObAAAaCqs?format=jpg&name=medium
What's Davey estimate for BSK ?
lol
Change Up
2012 ----------> bsk spoke about highgrade rocks and basement.
Somewhere along the way someone decided to just wash the rocks.
BSK's Reports say no blasting....first thing thst came to mind ?
Hammer drill rod on backhoe tearing up ivana decayed hardrock interior hump
( no blasting just hammer )
Storing waste rock for several years ?
Calling ore Millfeed ?
I see the word mill.
Add it all up ?
Loose rocks, ivana's interior hardrock,
3 km2 square -----> seen in MDA
World nuclear assoc estimate
MDA highgrade is there
Image beginning of post -----> reveals lots and where the highgrade is - rocks, slime silts
Maria's 1.5 km stepout and NE extrntion over 1 km strike 20 m depth.
Seeping heavy silty sediment greens = Picos watershed system.
Cheers.....
And here i thought i was done researching...
Happy i spent a few more hours gathering important pieces that bring clarity to
Ivana - Amarillo.
Post is not investment advice.
Perform your own DD.
What i've revealed ----------> backed by press releases and MDA.
Junior's website only offers recent press releases hmmmm.
If bsk was ever enlightened...
they'd work the angle reclamation - remove U from deposit and highgrade silts from salars.
clean water ways.
To think... Nickolaos in video says rocks aren't mineralized.
1 st image above speaks a different story. Gravels are also highgrade.
Me thinks.... helluva lot more U + V @ Ivana.
Those green slimey silts = just maybe my theory of U235 dropping out in salar is correct.
Aqueous bond to hydrogen then.... sinks to silts then carried out to ivana as
green highgrade sludge.
