Likely to be some issue with the reported grades IMO.
LUDD23035 53.5 119 65.5 3.33 1 LUDD23035 incl 53.5 77.1 23.6 10.3
I do like to check residual grades with data sets like this. However, for the numbers reported above the math gives an odd ball result.
65.5 3.33 218.115 to get 0 residual 1 23.6 10.3 243.08 3.71 % bulk 65.5m 2 41.9 -24.965
The high grade exceeds the m% for the overall section. Suggests an error somewhere. Not uncommon with large data sets.
Mathematically to get 0 residual the bulk grade needs to increase, 0% will not be the residual which is commonly 0.3-0.5% from past calculations I have done. Sometimes higher and with this dataset I suspect that may be the case for some.
Another MATHEMATICAL example
LUDD23007 66 101 35 2.22 1 LUDD23007 incl 66 90 24 3.22
35 2.22 77.7 1 24 3.22 77.28 2 11 0.04 0.42
11m 0.04% Nb2O5 residual???
It is not unusual for residuals to be sub ore grade. A Halo of lower grade can be useful for minimizing dilution though the two examples above would not IMO give that benefit. Errors? Mine or WA1?
=================
Satellite pass yesterday.
Perhaps two more sites added south of the X for 50m infill. Hint that most previously reported sites have been visited by a rig (sonic and/or DD).
The rest of the activity is impacted by a sudden change in "brightness" for the last pass on 2 June which makes picking 'activity' challenging.
Might have rained just before the satellite pass resulting in some changes.
Time lapse images last 5 days.
Highly optimised colour
Rain? Moisture index based image
The two new sites SW of the X show up well on this. Most of the other sites are as reported in my last sentinel post.
Surprisingly the western half of Luni is very different. No idea why.
The drill(?) sites are vague at best except for the one line in the east.
===================
DD and final RC assays from 2023 took some 6+- months to come back! Worth the wait though.
Location work I had done has been adequate with only a few DD sites missed. Accuracy generally within my hoped for +-25m range.
Spatial distribution of deeper mineralisation is going to be a tough one which will be left to a more appropriate time down the track. Something is there at depth but probably best left until later.
[LYC didn't drill below ~200m until a few years back when they stuck in an inclined hole to 1000m. Top ~600m gave low percentage REEs (1-2% from memory) which means more drilling down the track...perhaps.]
Will leave the crunching of data to others and look forward to the MRE.
