4 OPTIMIZATION ( potentials )- Course Gravels -----> crush, mill -----> potential uranium bearing ore
- REE's other elements are present in deposit
- Uranium rich waters ( mentioned in press ) brine extraction
- Capping was used in resource grading - lower grades applied vs keeping higher grade
4 Optimizer i'd be working on vs seeking new claims.
#1
Course gravels ( pea press ) stockpiled ( interesting ) 75% mass tonnage parked (
refer to my prior post )
75% of the mill feed mass from which most of the original uranium and vanadium has been stripped) will be dewatered, and either stockpiled on surface (during the first three years of operations) or backhauled by the mine fleet for backfill into containment cells within mined out sections of the pit. https://blueskyuranium.com/news-releases/blue-sky-uranium-announces-a-positive-new-preliminary-economic-assessment-for-the-ivana-uranium-vanadium-deposit-amarillo/ #2
REE's no assay values
by default ree's would respond just as well as uranium - dissolve into pregnant leach
Geostatistical analysis has been carried out on the geochemical exploration data from Ivana North. Elements which show positive correlation with anomalous uranium values include cobalt, copper, lanthanum, molybdenum, rhenium, selenium, and yttrium. Molybdenum and selenium display the best positive correlation with higher uranium values, a relationship also observed at the Ivana deposit (see Figure 2a-c). https://blueskyuranium.com/news-releases/blue-sky-uranium-provides-drilling-activity-update-for-amarillo-grande-uranium-project-argentina/ #3
Uranium Rich Waters testing sub aquifers or surficial water bodies for uranium + ree presence
= smart
= could exponentially increase resource size
The presence of lanthanum and yttrium is currently interpreted to be related to a process prior to mineralization where acidic water generated secondary porosity and prepared the host rock for the entrance of the uranium-rich underground waters from the regional mineralizing system. https://blueskyuranium.com/news-releases/blue-sky-uranium-provides-drilling-activity-update-for-amarillo-grande-uranium-project-argentina/ Resource Grade Capping PEA - Higer grades saw lessor grades applied
If minerals have undergone natural leaching sub surface by natural conditions
chances are -----> oxides or other mineral leach formats form richer grade
concentrate strata = resulting in higher grade values to settle / creating higher grade basement.
PEA does distinguish between upper / lower strata upper - 0.014% U
lower - 0.042% U
https://blueskyuranium.com/news-releases/blue-sky-uranium-announces-a-positive-new-preliminary-economic-assessment-for-the-ivana-uranium-vanadium-deposit-amarillo/ VERSUS - what i'm referring to are the 3 categories course gravels, red sands, sands
which contain far higher grades seen in chart below ( 2012 )
If 350 new holes were performed to establish Invana's new resource est
How many of the 300 new holes correlated with 2012's higher grade stats ?
PEA essentially reduced higher grades to lower grade capping.
2012 Grades Metallurgy Sands - 0.748% U
R Sands - 1.626% U
Gravels - 1.264% U
Catch it ?
2012 grades in metallurgy report ( chart below )
have no ( 0 ) right side of decimal
= wayyyyy higher grades
PEA grades have the additional ( 0 ) right side of decimal point.
Tweaking these 4 subjects above...
Does make me wonder just how much better Ivana could be.
Not investment advice.
Just pointing out what stands out when comparing historical vs current.
Cheers....
