Sounds real promising.

Disappointing as they seem to be taking a very longtime to release results on just two holes. The market is still in the lurch so the sooner that further verification comes through, the better. Ditau is a sideshow but a very important one. Still all to play for.Cash

Skiboy,

Thanks.

From the recent RNS

"An 80m dolerite sill was intersected at 281m."

Unpacking the secrets of South Africa’s dolerite sills



Excerpt from the article. I found this pretty interesting.

Two very different potentially economically important aspects of these sills are worthy of explanation. The first relates to gas preservation. Many analogies have been drawn between the gas-bearing shales in sedimentary formations around the world with the Karoo rocks in South Africa and the well-known issues about economics versus environment are vigorously debated.

However, the Karoo is the only example that has abundant dolerite sills. There are two potentially opposing effects of the dolerite sills. Gas formed from decomposing organic plant material that was buried under thick layers of sand and clay. Gas would normally leak upward very slowly through small pores and spaces in the rocks until it was trapped beneath a layer of rock that has no pores. We call that layer impermeable.

The dolerite sills form such impermeable layers and so may have acted as good trap rocks for the gas. Thus the rocks beneath a dolerite sill might provide a good exploration target.

But there is also an opposing process. The magma intruded at 1200 degrees Celsius. As it cooled it heated the surrounding rocks. The width of this heating zone depended on the thickness of the dolerite sill. The highest temperature at which gas can survive is about 250 degrees Celsius, above that temperature it will be burnt. That temperature will be exceeded for all the surrounding rocks that are within half the thickness of the dolerite itself (both above and below).

Any gas present in the sedimentary rocks at 180 million years ago within that distance of the sill would have been destroyed. Thus, a 30m-thick sill would burn all the gas within 15m above and below. At a number of surface localities the sedimentary rocks have been found to display a very unusual structure.

The rocks have been broken and re-cemented, and extensively altered. These features have been attributed to the release of high temperature fluids and gases from depth. Are they evidence that the intrusion of the dolerites liberated gases that streamed upward? If so, there may be less gas than anticipated. So we do not know what to expect the effect of the dolerite might be in terms of gas preservation.

Hidden nickel and copper deposits

The second potential economic aspect relates to nickel-copper sulphide mineralisation. A considerable proportion of the World’s nickel is mined from dolerites. The best example is in Siberia, Russia. In South Africa there was one small mine for nickel-copper sulphide mineralisation at Insizwa, near Kokstad, in KwaZulu-Natal. The intrusion is 1000m thick.

Although negligible amounts of ore were ever mined, there is chemical evidence that much larger deposits ought to occur at its base. The logic is that if an immiscible sulphur-rich liquid separated from the magma (like oil separating from water, or grease droplets forming on a cooling bowl of washing-up water) a considerable proportion of the nickel and copper would be extracted into the sulphide liquid, which then forms an ore deposit.

The remaining magma would then be depleted in nickel and copper compared to its original composition. Based on the difference between “normal” basalt and the Insizwa rocks it is possible to calculate that enormous masses of nickel-copper-rich sulphide ought to be hidden below the intrusion.

I know of four other dolerite intrusions in the Karoo that have this characteristic nickel-copper depletion with the implication that they too could host valuable metal resources at their bases. Would their exploration and beneficiation create national opposition analogous to that generated around fracking?

True, they may have gone to intertek who did the initial prep work. An endless list but as they will all be following the same test procedures to comply with international standards it will be a case of either who they know or who can turn the samples round quickly .... Of course it could also be the favoured farm in partners preference.

Jone,

This company is a likely candidate from what I gleaned from their web site. There are many more too.

You would also want to know when they were sent. They may have paid for a 'fast' turnaround. If they are only testing for certain metals the time will also reduce.. Let's say 3 weeks to test (first assays were stated as 4 weeks) and they have had them a week. Add another week for KAV review, RNS prep and review so it could be mid August. .I will still check for the RNS daily!

D220,

What I would like to know an I am sure all investors do is the estimated time to get the completed check on the Ditau assays at an independent laboratory in South Africa. Kavango have instigated this check imo to satisfy potential farm in partners interest.

ATB,
GD

[d220] 23/7/2019 09:20

GD Lol! Nothing serious I hope?
You are right of course, we are just in a waiting game. I am confident that it will be worth the wait!

[greatfull dead] 23/7/2019 09:09

D220,

Thanks. My excuse was I had just had a call from my GP...

[d220] 23/7/2019 08:54

For medical trials????

Arc Minerals 17 July 2019 RNS:

"Initial assay results for Hole 4 have shown some significantly higher Cu grades which are in the process of being further verified. These results will be released as soon as practicable."

My Comment:
A recent case of re-assaying as similar to KAV*s request for re-assaying.

Tried that. Fail. I'll have a look on a proper computer later Thanks

It's a screenshot and they don't display correctly on the phone app sometimes. If you're on the app you have to click on view full message.

Was that meant to be a blank post?.... It could be an issue my end

[jone06] 19/7/2019 15:37

Good volume for us today and the spread is reasonable

[mpls] 18/7/2019 16:51

Not long now IMO.


Genalysis carried out 12 duplicate check assays...

Kavango is currently undertaking its own program of checks and duplicates at an independent laboratory


The independent lab is only checking the high grade stuff, results next week me thinks.

[greatfull dead] 18/7/2019 16:25

Good finish on the cards. Nice.

People waking and reading the rns properly.

[mpls] 18/7/2019 14:39

A few more buys and we could be testing new highs
