The western extension of Crean had dropped back to a 150m spacing instead of regular 200m. A minor anomaly which raises some speculation as to why. Then back out to 200m.. Hence one possibility regarding width.
As Ozblue commented the Hoschke Crean system is open to the west as a fault with some carbonatite fill/dyking. Thinner at depth in EAL001 which is one reason the Aircore has focused on Crean where 100+-m intersections were present in 2023 drilling (Wider in the east but local??).
H-C is some 3.5 Kms along strike. Mineralised widths at the west end of Crean are probably less than 100m based on currently available data.
For interest sake only at this stage here is a volume tonnage calculation per 500m of strike. Reasonable data for such a length but extrapolating further fraught with variables. 3 sections available with this being the latest. Probably not significant but drilling south might be more appropriate given the northern dip interpreted here. Mineralisation in a horizontal blanket? Vs zonation in dyke?
500x100x 25 x 2(SG) gives 25 Mt. Expect width to be less but average thickness may be more SG high by comparison with that used in Luni MRE? If anywhere near real there may be some 10+Mt of material at 1%+ grade in this selected 500m zone. Extrapolate to 2 or 2.5 Kms overall with similar or slightly lower parameters Crean would be a good satellite deposit to Luni if not a standalone deposit. Similar potential indicated at Emily by today's assays. These figures to be treated as purely speculative. [Part of the possibilities for ENR @riglife}
The Luni MRE showed a zonation around a carbonatite core. Present here? Probably needs more drilling to define any detail or just simplified for convenience at this stage?
The end of EAL260 is probably very close to the WA1/ENR boundary. High likelihood mineralisation continues south onto WA1 ground. [As expected IMO}.
Good sign IMO to read Green had priority samples taken and sent. Fingers crossed for good results there.
==================
@ozblue I have spent some time trying to come to grips with the relationship of the Lake Mackay quartzite to known carbonatites. Certainly appears to be at least a superficial correlation. Exactly what the quartzite unit is is probably more complex than shown on the simplified geology interpretation.
Age wise Crean mineralisation is likely younger than the Elephant Island Fault (appears to be a fissure fill/dyke meaning later) which cuts the quartzite.
Fascinating regional geology in the West Arunta.
