Well, this is an interesting development.
What you have here, AUR geos (because clearly you gents have no clue and can't fess up to it publicly) is a Thduna lookalike.
Conisder the two core photos.
On the left, a massive bucky quartz vein with two stages of growth; earlier translucent white buck quartz and a later opaque quartz (carbonate?) infill, and possibly third stage of saccharoidal quartz. Within the interstices (gaps and corners for the laypeople) bornite has been deposited.
The vein has stylolytic textures running at a shallow angle to the core axis (probably vertical, bu the geo's should know since there's no ori line), which indicates that the veins predate at least one deformation event.
this is indicative of bornite being deposited within the vein system late in the hydrothermal event, and not as a consequence of volcanogenic massive sulphide systems. This, therefore, is not VHMS mineralisation.
The second photo is of a relatively weakly deformed green chlorite, carbonate altered basalt or volcaniclastic rock, with a late stage hydrothermal chalcopyrite-bornite veinlet, with some diseminated chalcopyrite in the matrix.
The blebby intergrowth of chalcopyrite and quartz-carbonate patches militates against this being VMS stringer veins, as any competent geologist conversaant with VMS alteration would be expecting to see intense silica-talc-smectite, sericite-silica or intense black chlorite alteration. The absence of strong pre-deformation textures in this veinlet really does it in for the VMS causation.
So what you have here is model-driven geology. The company and geologists look for VMS, and whatever they find, they find a VMS even if it is not.
In my opinion, this is a 1550 Ma associated hydrothermal copper mineralisation similar to Thaduna. If anyone has any doubt, then you should look up Ventnor Resources ltd's photos of the Thaduna mineralisation (I mean, I have seen the core, but obviously you dont have that luxury) and compare and contrast the textural and mineralogical similarities between these two occurrences.
Given the <1% for 165m of bornite, your best hope is an average grade of ~0.5-0.75% Cu for 165m, with of course a few sweet spots. This, if it persists for several hundred metres along strike, could be an attractive target for a very large low grade open cut operation. But remember, this is the best zone of the strike length, so it's likely all down hill from here in terms of grade and width.
Is this all bad? No. Thaduna is a middling-size, middling-worth epigenetic copper deposit which may or may not make it as an underground opportunity. But if Wodger is similar (early days) then you'd have to consider your potential economic returns more in terms of this than of DeGrussa or Monty.
