Hi Strudel
I’m thinking about it, long way , put me down as a maybe.
Do I need a passport and a translator:))))

Hi Stu
The ore body is vertical, the best shape for bulk caving , less dilution , weak grades become economical, gravity does the work after initial costs.
One fly in the ointment maybe the incline of the Dyke , huge overhang which may be causing the planners headaches in how to keep it up. Which could be the reason to stope and backfill the other side

Hi Stu
I’ve not taken copper or anything else other than gold.
There’s a lot of weak crackle at the top of the ovoid and down the sides of the northern corridor.
There is possibility that the average grade might go to 1g/t with the increase in volume of sulphides in the crescent and high grade breccia in the corridor but I’ve also reflected on the bismuth content which has a detrimental effect.
I would expect the companies average grade of 0.55 to increase to .75 over time.
Lower down though the average grade of 1g/t looks very realistic

Hi Bellers
I presume you mean the SE deeps.
The SW boundary has remained static all through this journey.
The SE deeps though are coming from the south and expanding lower down to the W,S and SE and May expand further.
The name refers to the crescent

Summarising my recalcs
Taken mainly from the isometric view on page 7
https://greatlandgold.com/wp-content/uploads/2022/03/20220310-GGP-Havieron-Exploration-Update-with-images.pdf

The top ovoid has been described as having a length of 650 and width 350m, the shape of this has not been static and is not a perfect oval shape.
The latest sections show it thinning in the centre, to explain this if you hold a plastic cup upside and press your thumb in on one side that would describe what is happening.
The calc silicate boundary or edge of breccia has expanded dramatically and is more prominent on the NW end a lot further away from the northern pod than first assumed. These calc silicates are very weak and progressively weaker towards the boundary.
I’ve seen no reason to change the overall dimensions of the top ovoid at this time or my assumption of 0.75g/t average grade throughout, using the high grade to counteract the weaker crackle.

The lower ovoid is what’s changing my assumptions.
Each progressive results have enhanced my theory of a lower ovoid, this time and January’s have grown this ovoid.
The incline of the Dyke is following the intrusions eastwards expanding the length.
The sulphide intrusion in the south is inclining southwards expanding the length and width.
The star of the show has to be the eastern breccia, expanding E,N and NW. It’s trend Northwestwards is expanding to the length and its boundary is still open.

What we don’t know at present is how weak those calc silicates are but they will more than likely go down with the rest of the ore while bulk mining.
I would put these in the same category as the Telfer extensions at the moment. These were discounted at an early stage as being uneconomic but now being considered due to price rises.

We don’t yet know if the breccia pipe keeps going down vertically or stems from the Dyke area but it looks vertical at the moment especially with the diorites in the centre.

Overall I would say a realistic sum is 25-30m oz plus copper plus a hopeful depth below what we have

I never thought I would see this 6,000 posts, so I think my recalculations from the latest drawings is probably an appropriate post.
I’ve taken into account the Dyke volume.
I’ve taken the high grade out to compensate for the weaker crackle breccia so a 0.75g/t I believe is reasonable.
The calc silicate widths across the ore body are greater than the top ovoid widths by at least 50%.
My lower ovoid assumptions are based on my progressive theories that have gradually become a reality.
As the bulk mining progresses the weaker grade are at the top so the average grades at the top will diminish over time.
Weak grades will collapse down when bulk mining into the drawbells, tests will be carried out some will go to the waste rock dumps not to tailings.
I’ve not taken out the recovery factors as their will be different % for different grades and bismuth content,
So my totals will need to be reduced by 10-25% depending at what time and grades they are processing.

Top ovoid
Area 176,000sqm
900m deep
Sg 2.7
Grade 0.75
= 10.3m oz

Lower ovoid
Area 1200x800m = 754,000sqm
Sg 2.7
Grade 0.75
= 19.6m oz
Total 10.3m + 19.6m = 29.9m oz

Lower Ovoid
At 1g/t
=26.9m oz
Total 10.3+ 26.9 = 37.2m oz

Possibility of achieving another 600m depth
= additional 29.4m oz @ 0.75g/t
Or
= additional 39.3m oz @ 1g/t

CONAKRY, March 11 (Reuters) - Guinea's ruling junta has ordered the cessation of all activities at the massive Simandou iron ore deposit, which is being developed by Rio Tinto and other companies, it said in a statement late on Thursday.

Hi Strudel
I have said I was nervous of Zipa I was unsure of the geology. I knew it wasn’t the same as Hav north and Artemis drill 7.
Geologists have told me it should be mineralised as it goes into Havieron.
Zipa 01 is about 750m from Artemis pad1 or drill 06.
They drilled east and I said to Paddy why have they drilled east away from the target, I couldn’t understand that, they must have some information for where they drilled.
We will have to wait for Artemis now which should be soon but if it hits it will have a beneficial impact the other side of the border aka Scallywag :))

Look at the plan on page 8
The striking thing here are the blue drills still in assays.
I’ve talked about 152
93A is targeting the same high grade zone as 152.
What about 153,154 and 155 where are they off to, nowhere near the ore body.
Are they wild cat exploration drills or are they testing for underground infrastructure?
Great stuff!

Hi Dillon
It’s not deep they hit the basement at Meadows with RC drilling.
The geology is Archean so it’s a lot older than Havieron.

Regarding the Northern Pod look at the cross section on page 10
https://greatlandgold.com/wp-content/uploads/2022/03/20220310-GGP-Havieron-Exploration-Update-with-images.pdf

The 2 hatched areas on the left is the pod, I’ve been watching it develop over the last 2 years and it’s been changing continually and it’s still not defined but could contain 1m oz in my opinion because of its size.
Check out the section above on page 9, drill 152 still in assay. It’s going through a cemented breccia zone with a high grade zone within. It measures roughly 350m long within those breccia, the drill itself carries on below the section shown for another 300m.
Nearly our deepest drill, this could be a stunner of an intercept

Look at the forecasts , it’s changed over the last few days. It’s been forecasted to be 4.13 by the end of the quarter on a downward trend, well it’s turned they are now forecasting a rise to 5.01 and 5.32 in 12 months $11,725 per ton.
This is down to inventories they are just not producing enough.
Bloomberg reporting the copper price could rise by 50% to $15,000

I wound Liam up last night asking where’s the best place to drill, I said Wishbone.
No not the company it’s on EG best MMI results were at Wishbone in the top NW. A licence we reapplied for.
Ernest Giles has a strike length similar to 2/3rds the length of the M25, reportedly having 2 areas containing 5m oz targets and some 1m camp type targets.
Would be daft to give this away. More likely to be gold and nickel there.

I was nudging Liam last night to talk about the Decline.
Progress is slow I was expecting it and mentioned it quite a few times.
According to SD it’s still on time and budget.
To prevent it collapsing they are having to drill a few holes then pump in a Sika resin, this sets very quickly and then the rock bolts can be installed.
With the Decline new route going across the contours and not following them down, the more firmer ground will gradually rise up the sides and the soft layer will be in or above the roof.
This will reduce the need for resin initially to the sides and gradually fade out from the roof which will accelerate progress.
When it gets passed the first ring of the spiral further machines can be brought in on other sections of the Decline infrastructure.
When it gets passed the 4th ring further machines can start on further infrastructure but these will be mining infrastructure yet to be announced or approved.
This is what the FS is for , to tie in the infrastructure plans and approvals besides valuing up the asset and Decision to Mine.

To me everything is tying in with the end of the year.
NCM are focussed on achieving the FS on time .
They are a large conglomerate with set ways of working they will not alter their way of working to suit our needs.
To me NCM provide a good news coverage with quarterly results.
If you don’t believe me go try and find anything to do with Winu on Rio website, took me ages.
If we were joint ventured with them we wouldn’t have had such news coverage.
Winu, try and find Budgiedown it’s not there

“Anglo-Australian miner Rio Tinto PLC announced Thursday it would sever all business ties with Russia following the invasion of Ukraine.

The company said in a statement that it "is in the process of terminating all commercial relationships it has with any Russian business".

No timeline has been announced for the severance, which may be a complex disentanglement given the miner's ties with Russia.

In Australia, Rio Tinto co-owns one of the world's largest alumina refineries – Queensland Alumina Ltd – with aluminium giant Rusal, which controls a 20% stake of the company.

Rusal, which was founded by Russian oligarch Oleg Deripaska, weathered sanctions from the US in 2018 – which were lifted the following year – but the company has since avoided any additional penalties during the recent wave of sanctions sparked by Russia's war on Ukraine.

Deripaska, who still owns a stake in Rusal through its parent company, remains under US sanctions, although he has spoken out about the Ukraine war “

I’ve no idea how they will separate from this joint venture

Hard to say much about the results without the drill logs.
Drill 145 passed through the NW pod , northern breccia and the top of the SE crescent zone according to NCM quarterly results in Jan.
Vertical depth reported today of 145 were :-
700m depth of ore in northern breccia
1,000m depth in Eastern breccia

700m is within the mining plan 4th level (NCM)
1,000m is skimming the top of the Eastern breccia.

From previous drill logs in the Eastern breccia namely 84, it shows the Eastern breccia starting within the sulphide.
My assumptions at the moment are these results are inside the sulphide ring and still testing the northern end of the crescent.

The NW pod has changed considerably over the last 2 years and I still don’t believe it’s shape has been defined but has always looked very interesting, I still feel it could hold 1m oz imo

The completion of the PFS triggered the completion of the Farm In so that NCM had the right of 70% of the Joint Venture and Ggp 30%.
The Farm In included (at Ggp request) for a 6 weekly update instead of NCM Quarterly updates.

Regarding Nickel
“Due to the highly skewed nature of the grade distribution, a grade capping strategy has been applied for variables including Au, Cu, Co, Bi, As, Pb, Zn and Ni.
Caps are typically around the value at a 99th percentile of distributions. 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.“

I would rather meet up with Hydro than a few on this Board

Get your facts straight Kevin I met Hydro at one of those 2 stag does

Is that a sly dig Sir loin

Last night door4left had a tee-shirt made with Havieron printed on it and his favourite drill
HAD117W6
That’s the one with 120m @ 10g/t

That’s an astounding drill.
Their are some very intercepts within that length
1.7m @ 130g/t
1.2m @ 311g/t
These have the effect of lifting on the whole average.

My personal favourite has to be HAD5 but HAD84 is such a contender @ 342m @2g/t consistent throughout that length in the eastern breccia.

The SE deeps increase in grades is a zone to keep an eye on
