Hi Learner
As far as I was aware the loan covered Greatland's share of the Decline, exploration and infrastructure and surely the new road is part of the infrastructure .
There's a lot of infrastructure along the road including drainage, turning circles,passing bays, petrol interceptors.
Ggp surely will have 30% of the cost of all this.

Should have said 40-50 road trains a day!

Looking at the Hannam note where they are saying 2m tons of High grade from late 2023, this they say is truckable.
2m tons divided by say 300 days a year allowing for breakdowns, servicing and time off is around 40-50 road trains varying from 125 tons to 160 tons.
I still believe some of the waste rock needs to be dealt with at Havieron.
I haven't seen any plans yet for additional waste rock tips apart from the Decline waste.
The mining licence trackway through Scallywag doesn't go as far as Blackbeard/ Kraken.
Is this due to the fact that they are waiting for exploration results so the trackway route can be finalised?

Hi Darby
Telegram keeps crashing my phone so I've given up with it.
What this board needs is the owner of the thread to have the ability to delete or obstruct users.
I've made some nice virtual friends on here and other boards and hopefully meet up this summer.
If I can find a new phone with a starting handle I might join Telegram :))

It's the copper supply that will dictate whether EV cars become the norm.
The copper price is already rising rapidly on supply issues.
To change to all EV vehicles would to take 2 large mines to come on stream every year to at least 2030 or 2035. This would be of 500,000 ton size, only one of this size has come on stream in the last 3 years globally.
The copper alliance web site seems blind to this shortage quoting recycled copper and undersea sources, I can't see either of those covering shortages and undersea is too problematic.
There's around 183lb in an EV car up from 20-45lb in a petrol car.
The copper price has risen from $3.60lb to $4.30lb in a week
Changing China's cars to EV would swallow the supply

Hi Ben
Glad you still busy.
It surprises me how bad some posters can get on their keyboards when share prices drop. I doubt it they would say it to their faces.
My nephew still working for Bovis around the Gloucester area, seems to be well liked.
He's got one their 3 storey houses, they are not my favourite design especially on green field sites, fair enough in town centres.
I am nervous what's happening with the economy, we are building on debt and what they're talking about on the other board with the silver market likely to break some banks is concerning me.
I'm still holding here at the moment but will keep reviewing my holding
ATB :))

I have to say I am embarrassed to be part of this Board.
The language and abusive posts were appalling yesterday.
You should hang your heads in shame.
For once you've left me speechless :((

Hi Tmt
Forgot to post the link

Hi Amateur
This is just the start, chronic shortage looming just when Newcrest start getting it out of the ground :))

Hi Tmt
Take a look at the BHP charts on this presentation
Tier 1 world class mine greater than $250m NPV(2006)
Look at what Hannam are saying and then see where you can put Havieron on those charts.
Havieron:-
World class Tier 1 asset looming.

Then have a look at how many were discovered of any real size between 1950-2006 (2000 to 2006 nil)
ATB:))

There is tremendous amount of information in that note and I believe they realise that there is still a lot more to come.
They have calculated a tonnage of 472m tons which is very close to mine at 484m tons. Now that doesn't include the bulge at the 900-1200 depth as that is below their assessment. My calculations take the tonnage up to 590m tons with the bulge.
They haven't taken any extensions either that are not defined but do admit this could be 600m deeper than their assessments .
They've used a $1950 gold price and a $1700 copper price, the gold price is a bit lower now but the copper price is way higher.
I am a bit confused by the start of the SLC production and not starting the block caving till 2028.
They have acknowledged this date may come forward.

At least they've reduced their gold grades from 6.4g/t to 3.8 which I felt was way over the top
Overall a better assessment than the last one in my opinion apart from the start dates

Hi Matt
Havieron to Kraken I doubt that would happen not that 6kms or so is that far but ventilation and escape tunnels are easily positioned down a spiral rather than a long run.
Nimitz though is a lot closer but it's deep around 900m .
The drilling logs results were said to be in the Havieron alteration so it may or may not be economical anyway.
Would be very interesting though joint venture wise how it would work .
The diagram on the Artemis Presentation showing an isometric drawing of their 3 drills and Havieron drills in the distance shows how close they are and imagine the spiral Decline in between

Hi Panama
Blue blood then
Royalty :))

Hi Nedd
Low grade will be leached and this loses a lot of minerals into the tailings.
As I've mentioned the crushed gold ore goes into the cyanide circuit and residual sent for copper concentrate this is where the cobalt will be found and sent to the refinery.
High copper ore goes into the copper concentrate.
Low grade will be leached and other minerals lost to the tailings.

Panorama geology from the web site

"Government geological mapping confirms the presence of coarse grained Archean sedimentary rocks
striking over 18km from north to south throughout the Panorama project area.
Geology of the area is predominantly greenstone and granite of the Archean Pilbara Craton in northern Western Australia.
The definitive source of the cobalt is not yet known
however it is likely to be localised in folding and faulting of the bedrock sequences
similar to other known styles of mineralisation in Archean greenstones elsewhere in the Pilbara displaying drill intercepts with high cobalt of up to 0.99%.
Historically the Pilbara Region is recognised for its gold and base metal mineralisation
but apart from the work by Anglo American in the early 1970s very little subsequent exploration work has been carried out within the Panorama project area leaving the cobalt mineralisation untested.
The large area of the cobalt in streams anomaly suggests a significant mineralising event has occurred.
The Mount Roe Basalt sits at the base of the Fortescue Group stratigraphy that is widespread throughout the Pilbara region of Western Australia.
There is considerable geological discussion as to the origin of palaeo-placer gold in the Pilbara.
It is known to occur in the Hardy Formation Conglomerate immediately overlying the Mount Roe basalt
and
it is also known to occur in a stratigraphically lower conglomerate horizon occurring at the base of the Mt Roe Basalt.
These palaeo-placer deposits are different to gold associated with other styles of mineralisation such as lode or epithermal types.

Hi Tig
I keep putting Panama too :))
Yes Panorama could be the largest cobalt field in WA or even Australia.
Cobalt doesn't come on its own either with Nickel or copper.
It's in the same geological zone as Carlow Castle of Artemis
ATB:))

Hi Oilmonkey
Cobalt will be a credit coming back from the refiners.
Cobalt is found in the copper concentrate, during electrolysis the copper in the copper anode migrates to the copper cathode, all the other minerals gold,silver, cobalt,arsenic , iron, lead etc fall to the bottom.
They are recovered and made into a cobalt anode and by electrolysis a cobalt cathode is made and rest of the minerals recovered again.

Before the copper concentrate process gold ore is sent through the cyanide circuit and gold dores are made about 70% gold and silver the rest mainly iron.

A bit more complicated than that but that's the general process.

In hole 006 cobalt peaked at 4104ppm that's 4.1% that's extremely high.
Holes 006-009 are the only ones where it is mentioned but looking at the logs it's right the way through them.
It can't have disappeared it's just not being reported by NCM who took over drilling from hole 009.

Highest cobalt ppm has been recorded in the Congo at over 6000 no where else is anywhere near so 4104 is extremely good.

in that same hole 006 copper peaked at 12.4% that again is extremely high

ATB:))

The first mention I can find of cobalt at Havieron is on the results for Had006,007,008,009
These were drilled vertically except 007 which was 70degrees to between 750-900m depth.

"Analytical results for HAD006 through HAD009 have now been received and are reported in this announcement.
Overall, every hole intersected mineralisation with broad intercepts reported in several holes. HAD006, HAD007 and HAD009 all ended in mineralisation highlighting the depth potential of the system. HAD006 intersected more than 367.1m of mineralisation at 2.0g/t gold equivalent, including 150.5m at 3.5g/t gold equivalent. HAD008 returned 89m at 3.6g/t gold equivalent. In HAD007 gold peaked at 21.75g/t and indicated additional mineralisation several hundred metres further east. HAD009 tested the deeper parts of the system returning significant copper intercepts from approximately 765m downhole to end of hole.
Cobalt grades have been consistently elevated throughout the mineralised system and it has been deemed prudent to add cobalt (along with copper) to the gold equivalent calculations. "

These calculations added 1g/t in places but generally 0.2g/t to the gold equivalent value.

"HAD006 was collared 50m south of HAD001 and drilled vertical to track mineralisation as seen in HAD001 and HAD005. HAD006 intersected desert sands and calcrete to 3m then Permian sediments to 424m before entering the Proterozoic target sequence. From 424m to 475m a barren mafic intrusive was intersected. From 475m the hole intersected mineralised brecciated calcareous sandstones to end of hole at 838m. Results included broad intercept of 367.1m at 1.15g/t gold, 0.44% copper and 176ppm cobalt from 471m to 838.1m (eoh), including 150.5m at 2.25g/t gold, 0.67% copper and 224ppm cobalt from 471.5m. Peak gold in HAD006 was 101g/t, peak copper 12.4% and peak cobalt 4,104ppm. Further intercepts are presented in Table 2.
HAD007 was sited 250m east of HAD001, angled at 70 degrees toward grid west, and designed to collect structural information on the host rock sequence. HAD007 intersected desert sands and calcrete to 4m then Permian sediments to 467m before entering the Proterozoic target sequence. From 467m to 550m variably silica altered calcareous sandstones were apparent; concentration of visible mineralisation increasing with depth. A barren mafic intrusive was present from 550m to 601m and then from 601m to 754.5m (eoh) silica altered calcareous sandstones were intersected with visible laminated mineralisation interspersed.

The cobalt is there at Havieron but NCM don't seem to publish anything other than gold and copper part from molybdenum at Cadia.

0.2g/t doesn't sound a lot but with the tonnage at Havieron @1,000m depth would give an additional 3.1m oz gold equivalent.

There's only 1 Havieron:))

Hi Texlax
Well we might have a lot of it.
Where molybdenum pushed the Cadia AISC into negative, cobalt maybe Havieron's negative
ATB:))

Copper price now $4.32lb
Cobalt $51,800
