News today from the Daily Mail about the USA Wheatland/Wyoming explorations JORC- claiming 2.3 BILLLION tones of RE deposits - Nd Pr easily accessible leach extractable with little radionuclide (U and Th) issues:
https://www.dailymail.co.uk/sciencetech/article-13062273/rare-earth-minerals-wyoming-green-energy-material.html
Wildest dreams doesn't quite cover the scale of this - it's 53 timesbigger than the total RE reserves of China (44 million tons).
Here's the JORC pdf if you want details:
https://app.sharelinktechnologies.com/announcement/asx/99e2b33b2d8382c24ed859bbd35d1dbf
• February 2024 JORC Resource is 2.34 billion tonnes
• 1.42 billion tonnes of measured and indicated resources were estimated at a grade of 3,296 ppm TREO using a
1,000ppm TREO cut-off
• Economic and technical evaluation supports cut-off grade at 1,000ppm TREO based on the net-smelter return
• Successfully preconcentrated TREO at a 12:1 upgrade ratio, representing a ~200% increase from existing flowsheet
design using low cost, conventional Dense Medium Separation
• Deposit remains open at depth and along strike
• In-Situ Resources of 419 million tonnes with a TREO grade of 3,349 ppm exists within ARR controlled Wyoming state
mineral leases.
• Close to infrastructure and a highly skilled workforce.
• Potential for remarkable scalability, with 75% of mineralised zones yet to be drilled and deposit remaining open at
depth.
• Deposit is from surface with consistent grades throughout making it ideal for large scale, low-cost open pit mining.
• Breakthrough metallurgy and mineralogy results reduce capital and operating costs opening the path to early
production.
• Environmentally and socially responsible with low penalty elements.
Wow.
Hogsnipe, A word of warning ~ ARR are either dreamers or pork pie sellers, they pumped hell out of La Paz and it has turned out to be a flop. ! A quick reality check :- According to their latest "News" release they have drilled a total of 9031 metres over both of their Wyoming "Project" areas. If we are very generous and assume an area of influence of 100m x 100m (10,000 BCM) for each metre of depth of drill hole and use an SG of 2.3 you end up with 207 Million tonnes and that's all. SO what are they basing the other 2.1 Billion tonnes of Indicated and Inferred resource on ????
Now any self respecting Geologist or Mining Engineer will tell you that it is stretching the friendship to classify a RE Resource higher than "Indicated" based on a 100m drill spacing and yet ARR are saying that this is Measured @ 200m spacing !!!! And if IT IS all Measured where on earth are they getting the other 2 Billion Tons from !!!!
FYI. The majority of Longonjo was drilled out at around 50m x 100 intervals; and 50 down to 25m with an average depth of 30m in the proposed Pit area. The drilling is still open on at least two sides and at depth, but Management are being honest enough not to speculate any Resource estimates beyond the drilling envelope.
A simple comparison of Longonjo:, and Halleck Creek at a 1,000ppm cutoff ~
LJ has a Total mineral Resource (measured, indicated and inferred) of 313Mt grading 14,300ppm REO. which contains 990,000t of NdPr; They drilled roughly 9,130 m in 300 holes to give an average depth of 30metres. ( Mostly the free dig shallow & weathered material )
Yet for roughly the SAME AMOUNT of drilling at Halleck Creek, ARR claim to have 207Mt grading 3720ppm; which they say contains just 187,000t of Magnetic RE's ! No comparison to LJ's is there really ?
Then , ARR have drilled down to 320metrs (which is probably one factor in calculating the large Inferred resource). Do you know how long it would take to mine down to that depth ? You might as well forget about anything below 120m when calculating a NPV(10) !
Lastly verbose cross promoting is considered bad form, a simple heads up and http reference would do..
China - thanks for a detailed (unlike you, I'll not say verbose) response and analysis.
I don't cross-promote and posting this information elsewhere would deny the silent majority of LSE PRE visitors a first look at a significant "Pensana parallel" development. I'll take your point though and cut the length in future.
Not that I'm cross-promoting, but I see ARR is up 18% today, so there seems to be support coming out of their recent news....
