Page 6 shows Havieron North from last August

If you want to see the geochemistry results for Apollo see page 30 of this Artemis presentation

Also page 29 shows the granite perimeter within the Havieron licence on a NW trend through Havieron North, Zipa and towards Apollo
Could this be the diorite Dyke line?

I thought yesterday’s NCM presentation was very good.
Analysing it I am surprised he never talked about deeper levels. He wasn’t referring to much below 800m of ore.
What are the SE crescent ‘deeps’?
Well this seems to refer to depths below 650m of ore and at this point the high grade isn’t a crescent it’s a length along the SE side. The latest drills in that zone are between 650 and 850m.

The high grade zones in the Northern breccia he is suggesting they could be linked into 1 system but he’s looking at depths no lower than 800m. They are suggesting it’s coming from a diorite Dyke running NW trend forming a corridor from the SE extension towards the Northern crescent and hopefully beyond. That SE extension shown on the isometric is at deep levels, the drill data picks up this extension below 900m so theoretically that shouldn’t be on that isometric or have they found something else , I’m not sure on that.

The Eastern breccia is down deep below 900m of ore and they have only reported 2 drills in that zone but there are 4 more unreported which they have shown the intercepts already, one in the middle looks really good while the one in the north end only has 2 small ones. This drill might effect my assumptions that the Eastern could be joined with the northern extension.

There’s still a huge amount of work to do to prove the extent of any of Havieron’s boundaries all still open. Huge amount of unknowns still to find.

My calculations for 900m depth of ore is currently around 12-15m oz of gold + copper and the footprint below this is much larger and as Fraser says the grades are improving.
My calcs including to 1300m is between 25-30m oz + copper but I will have to adjust that if the ovoid doesn’t connect the Eastern to the northern extension.
My assumptions that the Eastern breccia intrusion have risen up and into the Northern Breccia and SE extension haven’t changed but from what I’ve heard in that presentation they’re coming from NW trending diorite Dyke somewhere under the Eastern breccia or maybe further NE

Hi WF
I’m still intrigued from that one slide showing the Havieron layout to the north side of the red zone , is the south side much deeper?
What is it?

Well I’ve been expecting a jv with Artemis on Apollo for sometime, Apollo looks to be straddling the border into one of our new targets.
That looks the same as the Parlay situation in the Blackhills, part of it goes into Antipa land and a tail from it goes into Scallywag, I suggested a jv there sometime back.
Drilling may spark something:))

We’re drilling around those to define the footprint of the higher-grade and also to see if we can get that corridor to link to one bigger zone of mineralisation,” MacCorquodale said.

This would prove up my lower ovoid theory but that one remark on one slide got me nervous
‘limit of calc-silicate alteration “ on the North side between the Eastern breccia and NW extension .
I’m not sure if that refers to shallower mineralisation but that one drill that hasn’t been reported yet only shows a couple of intercepts and that’s lower down.

Apart from that one word some good stuff especially the 3 new targets Meco to the south and the 2 to the north where we were suggesting they would be from Artemis presentation linking up with Apollo

Hi Trigga
I doubt you will be lucky with receiving anything from the company in relation to the modelling.
The software would be under licence and under NCM control but good luck with that.
To draw by hand is time consuming thinking of the perspective and how the drills were angled.
My 3D image of the first 14 holes I found 3 drills that went down at 70 degrees were positioned pointing away from me as if they were vertical , so very hard to comprehend.
If I were to draw it again I would start with an angle such as 22.5 degrees then all of the drills would show their angle and not to show too many of them.

Hi Trigga
I’m due to do a YouTube podcast with Bottle Rocket soon when some of my sketches will be shown good and bad :))
He’s just done a Brew podcast with someone on Telegram so that will be out first.

The initial extraction of 2,000,000 tons high grade ore will have a great impact of revenues.
The copper grade of this high grade ore will be the major factor in copper revenues, this could be somewhere between 0.2% and 0.6%.
2m x 0.2% = 4,000 x $8,000 = $32m x30%=$9.6m
2m x 0.6% = 12,000x$8,000 =$96mx30%= $28.8m
(Based on copper concentrate price of 4/5th of current price)
If the price rises to $11,500 end of next year copper concentrate price would be around $9,200

0.2% = $11m
0.6% = $33.1m
That’s annual initial gross revenue to Ggp just from the copper

Hac9101 and 9201 appear to be directly above the drill Had117W2 where it sticks out from the ore body by 83m.
117 is a couple of 100m lower but it does appear something is going on to the SW

Historical drills Hac9101 and 9201 appear to be using the same grid system as Had01.
They are vertical drills roughly 500m deep.
Both have found mineralisation below 420m.
They are roughly over the top of the Decline.

My quandary as to whether the coordinates system used is the same as Had01 makes me hesitate to write that these 2 are 100m outside the ore body.
Examples 1m @ 1.04g/t from 484m and 0.73m @ 1.45g/t from 580m.

NCM have drilled through this zone but probably won’t have recorded it due to the cut off requirements.

Hi Trigga
I’ve drawn some 3D images by hand, it’s very hard to input data this way but I’ve picked up on a few things doing them.
The intrusion causing the calcerite breccia or concreted breccia appears to have come from the Eastern Breccia side.
Had02,03,04 appears to have just missed the HGZ and found crackle breccia
Had06 appears to have gone down the outside edge of the HGZ close to the Dyke and just clips the Hgz.

Hi Trigga
Can I ask how have you made a 3D model, have a software package or drawing it by hand.
Australian coordinates are a thing of mystery to me and trying to plot the original 5 Newcrest drill holes:-
9101,9201,9501,9502,9503 the last 3 coordinates don’t match the first 2.
There wasn’t a national survey company like our Ordinance Survey and different systems were being used by each State until 1966 when some form of an organised system was tried. There were changes in 1984 and 1996 which made the grid system 1.8m out of sync , the Australian Mapping Grid was changed in 2020 to conform to satellite imagery.
Australia is still split into coordinate zones of roughly 6 degrees longitude. Havieron is in zone 51.
The equator is not at 0 it has a false latitude of 10,000 and latitudes decrease going southwards.

Added complication is Australia is still moving NE at 40mm per year due to tectonic plate movements.
Yes in the 3 years since Had01 it’s moved 120mm.

All this and I still couldn’t work out why those 5 holes had different coordinate systems

I’ve always been intrigued by Ggp first drill at Havieron not really what was in it although the results were stunning.
It’s the first 78m?
I’ve plotted the first 9 holes and Had01 really surprised me how close to the Dyke it was.
The top zone is described as a biotite rich rock.
Biotite is a black mica described as rich suggests it has a large iron content.
From the top of the ore the Dyke slopes towards the SE lower down.
I’m now of the opinion there isn’t a weak zone at the top of the ovoid, I believe Had01 entered the Dyke vertically for 78m and soon as it came out was hitting high grade ore.
These results though however stunning and being the start of this incredible journey if it had been an NCM drill result it wouldn’t have looked so impressive.
NCM cut off grades for 1g/t has to have an average of 1g/t over a 10m length with 5m continuous run within it.
A lot of this drill would not have made the cut off criteria.
Had01 was NCM inspiration to invest though, it was also Ggp’s to drill Had05 into the top of it and Had07 to go below both angled drills from either side.
Had05 is another story :))

A statement from Alistair Clayton in June re their drilling campaign around the perimeter of Havieron

“ At the Paterson Central project, we have a significant number of drill-ready targets, that with a
single successful hole have the ability to transform the outlook of the Company. Our team is applying every resource required to achieve final ground-based heritage clearances to allow for drilling to start in the shortest possible time. We will update the market as these final approvals are met. Upon programme commencement, we will drill for the entire remainder of 2021, and as of today, we are completely funded to do so and more”

This is from an Artemis announcement in April
“ During Q1 this year, a total of 496x 1m intervals of half or quarter HQ3 and NQ2 core were sampled from the 3 diamond holes drilled at Nimitz in late 2020 (see ARV announcement to the ASX dated
17 December 2020). These core samples were assayed by ALS Laboratory in Perth, with standard samples and duplicate samples added for a total of 546x samples submitted for assaying.
Assay results were recently received, and some anomalous zones of low-level Au (10ppb) were reported over narrow to broad intervals, with only 5x 1m core samples returning Au concentrations above 50ppb or 0.05g/t (Table 1). Of these 5 samples, 1 was in a dolerite host rock (sample ID 89223) and the rest were in hydrothermally altered quartz sandstone, with all of these anomalous samples containing thin quartz-carbonate-chlorite veins and weak hematite staining.
These low-level Au assay results indicate that the Proterozoic Lamil Group meta-sediments and mafic rocks at Nimitz are only very weakly mineralised, and this drilled part of the prospect area likely represents a weakly altered distant halo to the Havieron gold deposit, located 3km to the West”

Hi Bamps :))
This is for you from the Commentary
“ All drillhole samples were composited to 2 metre intervals downhole and honouring the domain boundary. Ordinary Kriging (OK) of gold, copper, , bismuth, arsenic, lead, zinc and nickel were undertaken into 10 m x 10 m x 10 m blocks in a single pass run using a discretisation of 4 x 4 x 4. Sulphur, iron and cobalt were estimated by Co-Kriging (CK).The minimum and maximum number of informing composites were 10 and 20 to 24 respectively, depending on the domain and variable being estimated. Due to highly skewed nature of the grade distribution, a grade capping strategy has been applied for all variables including Au, Cu, S, Fe, Co, Bi, As, Pb, Zn and Ni. Caps are typically around the value at a 99th percentile of distributions. Restricted projection was also used in some domain / variable combinations to further reduce over projection of outlier grades. The model grades were estimated in Isatis software. Gold and copper were the only revenue generating elements, no recovery of by-products has been assumed. Variables were estimated independently. The block size was chosen on the basis of estimation quality and likely scale of mining.”

They use a Kriging method to put boundaries between minerals and they have been too variable to achieve so cut offs for these other minerals apart from Gold and copper have not passed the cut off grades.
It doesn’t mean that there not there only sample testing the ore will confirm this.
Note there is no silver

From the Commentary again
“
Further work

Infill drilling is underway on the top 350 vertical metres of the South Eastern Crescent within the existing resource outline, looking to upgrade the resource category to Indicated.

Growth drilling is planned to extend the limits of the mineralised system and infill drilling in the existing defined breccias looking to establish new Inferred Resources outside those stated in this announcement.”

That really tells us what to expect
350m depth of Indicated from the 650m of Inferred last time plus additional inferred from growth drilling.
The Indicated then maybe lower or equal to the last one but the Inferred in December will be larger

Hi Hydrogen
This is also in the Commentary
“ Metallurgical amenability is derived from preliminary testwork on 10 composite samples based around the current operating Telfer Plant process. Initial results suggest gold recoveries of 94% (Crescent Zone) and 84% (Breccia Zones), and copper recoveries of 92% (Crescent Zone) and 82% (Breccia Zones).”
