The boundary is some 700m SE at the closest point but the geophysics (gravity/mag) shows the trend is probably not useful for nearology.
The white line is the southern margin of the main gravity anomaly in this area. The red the localised gravity high which P3 drilled into and indicates 216m of Carbonatite (less overburden) for the down hole length - ~~170m vertical.
The gravity outlines above are schematic and taken from this image.
COLOURS- GRAVITY,

Carbonatites have an SG that is often higher than gneissic/granitic rocks - enough to give sufficient contrast to create a gravity anomaly - Works for Mt Weld, Cummins Range. Olympic Dam is hematite rich as well as having sulphides so also has a gravity signature.
Hole EA1 of ENR is more like the OD than carbonatite judging from geology logs.
Either are acceptable if grades and size keep coming.
BHP and Rio (among others) have been searching mainly for OD style mineralisation with some teases. Top Up Rise (TUR) was drilled by CZN in 2013/4 with only technical success. Details of work by the majors has probably disappeared into their archives other than statutory requirements which may be available.
Top up rise may have similarities to ENR's first hole in terms of Cu grade and geophysics, but the REE component may be higher (or not analysed at TUR).
At last year's AGM there was a bit of a buzz about Aileron and the serendipity of the first hole. [ paraphrasing comments at the meeting: Jon Hronsky was apparently, probably still is, a real fan of Aileron based to the geophysics and his vast experience. ] This didn't translate into much activity over the last year.
The cat has got amongst the pigeons with the WA1 hole and the ENR airborne survey is a great start. Airborne gravity would be good too but probably needs magnetic/radiometrics to refine the area.
The stars are rough locations of other WA1 drilling with assays pending.
Only tenuous magnetic correlation to the east of WA1's hole. None probably other than a broad trend which is mostly on WA1 ground for the first 8 Kms or so towards EA1 20Kms away. The Shackleton chip sample is closer on ENR ground.
Definitely a poorman's nearology play on this basis.
Looks like an earlier moderate to high resolution magnetic survey has been done over much of the ENR tenements. Some strong fault in the east as well as folding.
======================
Jon Hronsky's modelling led, in part, to discoveries at Nebo/Babel, Tropicana, and Karlawinda. Follow the major structures and try to predict the large scale plumbing systems that might create a mineral system. I don't know how how many failures or technical success the WMC team had but the 3 above more than paid for their salaries. N/B soon to add to it hopefully.
