Intro: two sections - first on NE structure local to regional. Second some comments on tenement changes.

And what is that linear NE structure then?

Hadn't noticed that snippet before so with inimitable overkill here are some images to DYOR with some comments from me.



At this scale for the magnetic first vertical derivative there is a strong linear mag feature extending SW from Parklands in the Telfer direction HOWEVER it probably swings SE and follows the structure formed by the Wilki Dome. IMO it does not extend to Telfer some 2 -3 Kms to the SW. At least as a readily visible feature. [See below for a regional gravity perspective.]

Zooming in on Google Earth shows what I interpret as a sill up to 20m wide on the NW side of the Wilki Dome.

This is the largest of a series of bedding parallel features (sills?) that can be seen in this image and were (probably) mapped by the GSWA as such.


Dyke/Sill swarm: 1 highlighted on GE image above; 2 visible but appears more a composite of close spaced bodies; 3 relatively thin bodies mapped parallel to bedding.

Exactly what the black units are is not too clear to me. Not quartz, maybe a fault but looks more dyke like.
Whatever these units are there is some correspondence to magnetics. The NE red wiggle matches the mag high. SW one only partially.




Both they and the surrounding Wilki sediments are locally offset by minor faulting suggesting a different timing, if they are dykes, to other dolerite dykes (eg the one at Havieron). Beyond my pay grade with available data.
Options - Sills, sedimentary unit with local magnetic signatures; fault structure (unlikely): other.....

===========================
Fascinating geology in the Paterson looking further afield than Parklands with Geoview based imagery for weekend musings.



The strong magnetic feature at NW Wilki Dome is similar to many regional linear magnetic features. A magnetic unit within the Wilki formation? Vaguely recall such a beast being mentioned in the Citadel area.



The West and SW part of this image contains the western margin of the Paterson province and extends into the Pilbara Craton to the west.
Are the magnetic features at Pacman/Tetris related, in part or whole, to the Wilki "magnetics" units? IMO they seem broader and perhaps stronger given the depth of cover (>=1-400m).

1VD vs TMI? magnetics



Gravity



The low resolution Geoview gravity pixelates as you zoom in but gives some clarity in images like this.
Red line is a linear NNE/SSW feature that gets interrupted in the Telfer area - apparently.
Black outline is for a fairly distinct gravity "domain" around Telfer. Different survey with more close spaced readings or a real feature.

Maybe the red line is the feature mentioned in announcements?

====================
Tenement activity pops out from Geoview.
Some statutory surrenders have led to pegging overlaps that the Warden will have to sort out. Most new applications came in last year so may already have been mentioned in some threads. Believe the partial Surrender by Rio just west/NW of Havieron was such a case with AZY and NCM (still in Geoview) sharing some.
One thing I noticed was some very large miscellaneous licenses applied for by AZY and Rio in the Minyari and Winu areas respectively.




Winu/Citadel

Multiple misc licenses around Winu including the one shown that extends to cover Rimfire! Not Calibre?
Blue are pending, Green granted ground.

===========
A search for AZY + JV partners yielded 94 tenements with a widespread scattering off to the west in the Pilbara area. Perhaps consistent with the mission statement to keep looking, acquiring, exploring.
