Hey Goldworm, I didn't have time to reply earlier but good to see a different viewpoint on the mineralization at depth. We'll have to wait and see what the intercepts say but one thing i'm looking for is if the host rocks have changed. If we're still in carbonate rich material and have more granitic intrusions, the Sn-W becomes more plausible. My big question about that then becomes, what is the relative timing to Havieron? Because my understanding is that Sn-W often forms late in the orogenesis whilst intrusion related Cu-Au is a bit earlier. If however we are out of the lamil group, we might be hitting the Rudall basement at which point these are metabasic rocks which may be a good host for things like Nickel. Otherwise to get nickel, we need ultramafics. I really enjoy these type of discussions. I don't know if you have my email but seeing as you are someone with 40yrs or so experience in economic geology, i'd love to chat theory with you at some point?
CT hey, you are very welcome :-))))

Cheers Tom. Tomorrow it is.
Bamps/Paddy/Goldworm/Hydro - your enlightening discussions below represent everything good that we should see on this board, especially for non-geo's like me. Long may it continue!
Welcome back hydro.
Regards
CF
CT hey, think you will find its tomorrow night / Thurs morning :-)
Tonight's results will add value to GGP.
Nice thread on the above subject, someone recently posted - yesterday or day - what previous assays we are awaiting - 21 holes excluding anything since? Do we know how many are outstanding from Eastern Breccia?
This is indeed an exciting possibility and interesting comments from Goldworm. Waiting with anticipation
Would be interested in your take on the direction of travel so far in the ggp narrative goldworm.
I don't expect Nickel hydro but if there is a more mafic gabbroic intrusive associated with the havieron diorite then yes - its a possibility. Havieron has affinities with Skarn deposits where an intrusive has been emplaced into carbonate-rich sediments and hyrothermal fluids react with the carbonate. If the intrusive is a diorite, as at Havieron, then the Skarns are copper and gold-rich. If the intrusive is a granite, maybe fractioned from the diorite, then the Skarn will be Tin and Tungsten-rich. I would expect a range of different intrusive types to be found at Havieron but that is for the PhD student in Tasmania to find out or for Shaun to tell us.
Hi Goldworm
The drill logs suggest that the Eastern Breccia is feeding the Northern Corridor there’s no break it’s continuous.
The drills have only entered the top of the EB
Only Had90AW1 has gone slightly deeper if there’s any differing minerals to what we know at present it might be from this drill in tomorrow night’s announcement.
The copper grades are weakening in the EB.
Surely tin and tungsten would be from a younger intrusion and possibly different granites
@Goldworm - I'm sure you are right about the subtle and not so subtle hints that Shaun has been increasingly dropping over the past weeks. It's completely evident in his demeanour and the emphasis that he puts on the new geochemical signature found is telling IMO. I just hope we start to see this emerge in the results tomorrow night.
If this is a completely new pipe which sits alongside the main Havieron pipe then what's the possibility of that being repeated again further North at Hav North - thru Zippa and on to Apollo??
Exciting times for sure - Paddy
No lunch or insider info. hydrogen but when you have worked for over 40 years in economic/ exploration geology you get a second sense of how things are going to develop - especially the little clues that Shaun is giving. My gut feeling it is a completely different breccia pipe with different ore mineralogy. Hopefully no Uranium and Thorium.
Just a hunch Paddy but the indication from Shaun about a different to the Eastern Breccia was a good clue. Is the geochemistry of host rock or the ore mineralogy different. I expect both and that this is a different breccia pipe nested up against Havieron. HAD0084 is the deepest hole so far and is into the Eastern Breccia. As you go deeper into an intrusive hydrothermal system expect higher concentrations of metals like Tin and Tungsten especially if the source rock is more granitic. If it is a separate breccia pipe it could be bigger than Havieron. Fingers crossed but very exciting
Hi Hydro. What was the reason for your absence? You do not have to answer if you do not want to. I am just interested to find out what was it you said that caused the grief. Did you get too close to the truth? ATB Speedy
Second all these welcome backs- was worried hydro might have walked.
Welcome back Hydro!
Great to see you back. :-)
BTB
Agree with that sentiment
Good to have you back Hydro ;-)
Good to see you back posting Hydro. Hope you had a good break :-))

Welcome back Hydro..... ATB
Interesting theory Goldworm. Any particular reason why you have that hunch - is it purely down to Shaun's description that there is a different geochemical signature from the Eastern breccia?
I must admit that I am rather looking forward to seeing exactly what is lurking at the depths in these step-outs at the Eastern breccia and then on up to the proximal targets of Havieron North & Zippa.
I can see on the satellite image from planet.com that there appears to be activity on the most North-westerly Zippa pad which is the closest one to the Apollo target on the Artemis ground.
Things really seem to be hotting up out there (and that not just the summer season coming in).
ATB - Paddy
Nice to see you back H..
Looks like the Eastern Breccia is a separate discrete pipe which will have a different intrusive source for the mineralising fluids. The intrusive source for Havieron is a diorite so Cu-Au mineralisation. My hunch is that the Eastern Breccia "pipe" is sourced by a more granitic intrusive so expect to see metals like Tin, Tungsten, Molybdenum at depth as well as gold and copper
L-A When you read that again, you know its going be great, a new CEO of a company that got a 30% share of an already fantastic find would never risk his career to ‘ramp a new find.’.
Its as plain as day this is going to very significant
