There hasn't been much activity obvious at Aileron for the last few Sentinel satellite passes. Could have posted after the last pass but not really enough. Lack of obvious aircore over the last 10 days led to the comment below.
I suspect the aircore rig is either suspended or, more likely, off site with this the interpreted status for holes drilled and reported.

Reported targets not drilled highlighted in red. I have checked these locations over the last few passes and seen no activity. Any drill access is highly likely to be readily visible.
The average depth for reported RC holes has been ~83m. Since then I suspect some of the drilling has been relatively shallow so the overall average has probably reduce. No idea what the average depth might be, or exactly how many holes drilled so gave a range of depths. Probably 40 Kms or so drilled this season which, if near correct, doubles the original plan and covers large areas on a first pass basis.
[As part of the search I spotted 3 probable sites on WA1 ground west/SW of P1.]
Since the presumed exit of the aircore rig the visible changes have been at Emily and the Hurley to Crean gap with my guess being there is a dedicated RC rig on site.
Emily.
I like, but don't fully understand why, the recent two lines of aircore drilling west of EAL098 have had nearly every site revisited to produce an expanded visual disturbance pattern.
One possibility is extending existing A/C holes well into fresh rock - one or two rods? Not done for hole 225 but perhaps 260 so all this may be a figment of my imagination.
The sequence
Emily aircore and beginnings of WA1's wide spaced access and site prep (320 spaced fences X 150 spaced holes)
Gap
Then the majority of recent aircore sites suddenly blossom. WA1 work continues with the last new site (magenta diamond) just SSW of the ENR aircore.
On google earth
I like this activity because it hints at the possible 400m westerly extension of mineralisation in 98, 225 and 260.
Though why not complete the 200m infill to the west which suggest the thin red outline given for mineralisation might be close to reality.
===================
Crean to Hurley Gap.
Two sites - magenta diamonds - drilled ~800m west of holes 442 and 552.
Most previous aircore and RC (87 88 2023) drilling in this immediate area failed to reach bedrock.
Time lapse
Most activity happens between 26-31st of August.
=========================
Do not expect vast areas of carbonatite to be discovered with the widespread aircore drilling. Possible but unlikely. Certainly hope there are some good hits.
Most obvious locations for high grade blanket extensions are the 4 extension lines west of Crean high grade - potential for 600+m more goodies.
Likely 200m west extension from EAL98 at Emily and maybe another 200m though suspect the lack of an easily drilled A/C line or two to the west suggest mineralisation may be closed off to the west. Not to the south, yet, onto our neighbour's ground.
Other sites (Joyce, Shackleton, McIlroy etc) are IMO largely "stratigraphic" holes to suck and see what is there. Some geophysical and geological justification which hopefully will tag some targets.
Mawson and Perce? Lack of announcement perhaps implies not great for carbonatite or IOCG mineralisation. Avalon drilling and perhaps Caird suggest mantle related mafic intrusives +- syenite/carbonatite/lamprophyre as sources for mag/gravity targets.
Musings only, DYOR and keep fingers and toes crossed for better results at Green and elsewhere.
There hasn't been much activity obvious at Aileron for the last...
