This is my view on Antipa's results at Minyari deposit-

Mineralised intrusion inclined about 45 degrees rising from the SE to NW
about 600x200m
3 dolorite dykes running through it
A higher zone within the intrusion about 50m wide.
About 200m cover
The weaker zone grades look uneconomic.
When looking at the logs ignore the inclusions, the average grade in the intercepts is what to look for and how much gap(uneconomical material) between.

There are a lot of comparisons to Havieron on their web site but Havieron's weaker zones are very economical but Minyari don't look it.

I would suggest there is a lot more drilling required to assess what's there even though there is a lot already done.

The exciting thing about it, it's on the same SE -NW trend line from Havieron-Winu including Scallywag and Blackhills

Hi Tom
No confusion
GH and CB were both issued 9m @ 2.5p and 9m @ 3p
Nov 2020 Annual Results page 60, note 17

It was definitely GH and good luck to him :))

Getting 6m tons out of the mine from SLC operation is going to be a big task.
Hannams say that 2m tons is just about truckable using the existing Decline design.
A conveyor is no good round that spiral.
SLC operations about 800m deep a new conveyor Decline at about 10 degrees incline would give a straight length of 4.5km away or 4km horizontal.
Roughly where the end of the road application finishes maybe?

Hi EDM
All mining processing has nasties.
Gold goes through the cyanide flotation circuit.
Sulphuric acid is a by product and then used in the copper concentrate circuit.
Then there is the arsenic out of the rocks to be dealt with.
There's nothing inadversely nasty processing REM minerals , that chemically can't be dealt with.
In Australia they wouldn't be allowed to dispose of contaminated waste which would cause environmental damage.
Most of the waste goes into the tailing ponds

Hi ProfQ, Hydrogen
There's drainage works to go in yet on the shelf before the shot crete.
I'm expecting the floor to be concreted first before works to side or portal entrance.
Roads being built around batching plant area.
This has got to be there for maybe 40 years so they won't leave it unconcreted

Read the last Scallywag RNS and the listen to this lecture on alteration
https://m.youtube.com/watch?v=jC_plOvBwlE
Detective work on finding the hot zone using minerals.
Scallywag has hematite, monzanite so pay attention at the end for the magnetite alteration to hematite.
New techniques to discover ore bodies undercover

Should be an exciting few months to come
From the web site

The 2021 Work Programme for the Juri JV will include the following activities as agreed by the Juri JV partners:
? Drill testing of several high-priority targets across the Paterson Range East licence, including Goliath, Outamind and Los Diablos.
? Drill testing of the Parlay target, a discrete magnetic anomaly with coincident gravity response in the south-west of the Black Hills licence.
? Ground EM surveys to better locate and prioritise multiple additional targets through Paterson Range East and Black Hills licences.
All heritage clearances and government approvals have been received for these initial drilling activities. Field activities for the Juri JV are scheduled to commence in the coming weeks with field camps and infrastructure being established ahead of drill rig arrival.
Currently, the first drill rig is due to commence by early April 2021. Supporting heritage surveys will be completed over new targets ahead of ground geophysical work and additional drilling.

Hi Djf
At the time they produced the modelling there were no historical drills and no AEM survey.
It's only those 3 drills pointing them towards Teach.
A37 and A38 have been more defined now by the AEM survey.
There is still something around A37 don't write it off, you have to remember every intersect had copper, bismuth and zinc .
The hot zone is either close or down deep.
No one knows at this moment in time , lot of research still to do.
ATB:))

In the appendices on the Scallywag jorc report they have said there were 1495 samples assayed but only 46 reported .
I'm not sure if that means for the first 3 or all of the 7 drill holes.
That's a lot of sampling

They're going to have to redo their modelling it's out of date with this information and fit the next 4 drill holes into it.

From what Paddy just showed me about the A37 new target which is Kraken,London and north end of Blackbeard this is my post from 13 Dec

"Just reviewing my calculations on Scallywag, starting afresh I've been looking at the IP chargeability plan where they show a few cross sections.
These cross sections are a bit on the small side but it clearly shows Blackbeard and London continuously linked.
Moving round with the cross sections hinged at London, the one towards Kraken is hit and miss.
Unfortunately they haven't provided one from Kraken to Blackbeard but when you look at the 2d magnetic cross sections the anomalies at Kraken and Blackbeard widen out considerably as they go down.

I might not be right here but all 3 of these targets look linked.

For Kraken I have scaled measurements at about 1,000m depth by 750m radius
so volume of a cone is
Py x r2 x h/3
3.142 x 562,500 x 333 = 588,459,874 cube
x3sg = 1.765bn ton

Bamptastic:)))"

The AEM survey seems to be suggesting what I was saying back in December those 3 targets look linked but at depth
Really Bamptastic :))

Hi Dillon
That's not a daft question.
If you look at Appendix 3 in the Scallywag RNS it shows the 7 drills coordinate positions , the reduced level it started from , the dip or angle and then the azimuth.
The dip on Bld001 was 90 degrees from horizontal so that's vertical straight down
Krd001&2 were 70 degrees
Krd 003 55
Lon001 70
Lon002 65
Lon003 70

The Azimuth is a bearing 0degrees is north , 90 degrees is east
This indicates which direction they drilled

The depths are shown on that appendix

ATB:))

Looking on the RNS of the Juri jv I was quite astonished how many historical drills have been carried over 2,100.
However when analysing these drills :-
Air core drills
Average depth around 20m
Majority = 75%

RC rotary circulation about 20%
Average depth 80m

Diamond Drill About 10-20
Average depth about 130m

A few drills were unrecorded

My conclusion from this is air core drills are cheap but will not reach mineralisation under cover
RC drills do not penetrate deep enough to mineralisation where there is a cover but do allow a cheaper option to drop a diamond core in afterwards.
It's no wonder historical drills did not find mineralisation when they didn't drill deep enough

interesting piece on assaying gold, simply explained

Hi Panama
Big distance hugs :))

NE drill pads
Most of these drill pads from this side have been aiming for the SW side at depth or the centre of the Northern breccias like No48.
In the March results shorter drills were targeting the top of the SE crescent on that side.

The SW drill pads target the centre or the eastern breccias at depth 101 being one of the longest they've undertaken.

The latest step out drill pads to the NE , I would assume they are entering the ore body halfway down and carrying on to test the connection between the northern /eastern breccias.
I doubt very much they will reach the far side

Hi Lam
Thanks for the encouragement, I am very critical of myself. I asked Bottle if there was any chance of putting up screen shots I think I would have been more fluent but I am a slow thinker which probably came across.
It was only suppose to be about 15 minutes and lasted an hour , only touching some subjects.
Stick a map/plan in front of me and I could carry on for longer.
More like Fred Dibna thanks Mr B :))

While there's no one about and I can chat to myself I've been wondering how Havieron got there in the first place.
Magic said don't go there it's an academic question but I will air my thoughts and be shot down afterwards.
I asked Magic what came first the sulphides or the breccias, answer as above.
I noticed a hand sketch by Hydrogen of the volcanic pipes showing the centre breccias and sulphides joining over at the top and then weathered and recovered with the 420m of Permian cover.
This is the picture I had in my head but I've started to question it with new results.
From the sections just looking at the breccias it looks like the crackle breccias came first shown in yellow containing a lower grade of gold.
The concreted breccias look as though there was a second intrusion forcing or changing the crackle to concreted.
Was this caused by the sulphides, possibly.
The crackle breccias don't seem to extend to the top of the ore body apart from round the orebody perimeter. There is a maffic intrusion about 50-70m at the top that breccias didn't get through .
My theory is as the breccias were forming it couldn't get passed the intrusion and when cooling formed a shrinkage crack around the perimeter allowing the sulphide ring to intrude through the crackle breccias changing them to cemented.
These sulphides hit the intrusion and widened outside of it and around it to the now top of the ore body.
I'm unsure now whether the top was weathered down or not I'm starting to believe it wasn't.
You can see why Magic said don't go there it's puzzling Academics!
I've got that out of my head now :))

When you look at the drilling RNS, the slice plans don't really show what's happening at the Northern breccias.
Northern breccias are concreted breccias the grades are fairly consistent 1-2g/t, they don't reach the 4700 slice and shouldn't be shown there.

What's happening
The concreted breccias look to me as they're intruding into the crackle breccia, they are coming up from the Eastern Breccia. This 'plume' of concreted breccia is all interconnected.

Bit of speculation from me but I reckon the Eastern, northern and the NW extension are all connected feeding the northern breccias HGZ.
Question is how will they extract the pockets of HGZ. My guess would be another Decline tunnel to the North crescent for extraction before the bulk mining starts
