Not held does not imply lack of knowledge or a negative agenda. Though sometimes does. Welcome to the internet.....
Unfortunately for Aileron well put.
Like many companies ENR do have other irons in the fire that could help the SP in the longer term. Unless there is something special tucked away in the remaining A/C results the RC follow up is likely to change the extent of the known high grade Nbx areas in a material way. IMO
Hurley diamond drilling is IMO an example of this.
The diamond drilling does not appear to have expanded the narrow, nearer surface, supergene blanket AT HURLEY. The upper two intersections shown in 442 and 552 may be lateral but deeper extensions of EAL 283/4 zones. As is likely to be the case in larger carbonatite zones there is probably a vertical and lateral zonation of mineral zones (Nb, REE, Phosphate etc) as shown by the simplistic plot above for Nbx. Background values are commonly 0.2-0.3% Nbx using a 0.2% cutoff so probably 0.1% is normal in the Hurley carbonatite (= Crean?).
Emily. The latest assays contracted the likely extent of Emily (ENR side) relative to my previous estimate. The western lines limit extensions in that direction. Hole 261 probably is NSI at 0.2% Nbx cut off.
Revised area of possible mineralisation: This new shape roughly halves the previous area of ~200,000 sq m. BACK OF ENVELOPE TO BE TREATED as order of magnitude estimates ONLY. DYOR. With wide line spacings so much can happen though more likely on the downside unless some real surprises...they can happen. Based on WA1's MRE 200 Mt at 1% including 53 Mt at 2+% Say 12Mt at ~2% within 30-50 Mt at 1% for the 7 higher grade, known, zones of ENR.

[Note area used is essentially the vertical projection to surface of zones in drill holes. Thickness is assumed to be that of a sub horizontal supergene blanket with intersections roughly corrected for hole dip where necessary (-60 dip gives ~ 0.85 factor for vertical thickness)] ==================== Lack of urgency for Mawson and Perce showed up in the assay results. Joyce? Perhaps the same, but time will tell. Shallow cover in the east is seen as a positive which could make Steller, Crabeater and Leopard targets suitable for aircore testing. High gravity, low mag at Perce explained by mafic lithologies and some lamprophyres. The latter have been previously reported at Crean and, from memory, in the southern belt by CGN and RCR. Association exists with carbonatites so the eastern tenements in the NT (Aurora?) may have some potential.
================= Very distinct chance of over supply for the Nb market especially if the current round of world wide Nb exploration meets with more success. Many market forces at play such that only hind sight will be definitive IMO. Ask anyone invested in Li,[ Co, U historically anyway].
