Dutch Central Bank Admits Preparing for a New Gold Standard .....

Help Support Gold Refining Forum:
Y'know, something I've wondered--in light of all the "I have XYZ precious metal from XXX deep fissure/vein/mineralization at insanity/ton"--what is the etiology of gold nuggets? Sure, they wear out of the face of exposed deposits, but where did the mostly pure gold come from? Gold (and the PGMs) are siderophilic, so what type of geological enrichment processes have to occur before you end up getting chunks of darn near pure gold?
Also, what's the deal with these meteorites that have these preposterous densities? Bad math?
https://phys.org/news/2023-10-periodic-table-superheavy-elements-ultradense.html
Gold is rather on the border of siderophile and chalcophile characteristics.
This follows from its position on the atomic volume curve. It is at the beginning of the ascending branch of the curve. Below gold on the curve are typical siderophile elements, and above gold are chalcophile elements.
Native gold is mainly crystalline in nature; it has no zoning (usually), but has uniform growth of crystallites (dendritic crystallization is very rare). Many paired and polysynthetic twins, usually in the octahedral plane. All this emphasizes the non-uniform and abrupt development of crystallization under natural conditions.
Although zoned nuggets do exist, one was found by a gold digger in North Carolina. One end of the nugget was of gold, and the other was of silver. And between them, apparently, there were all the transitions.

Interesting Information about meteorite
because sometimes in the desert of california and Arizona
You can find some pieces of meteorite
I have found very small pieces
Those pieces are
mostly Iron,very heavy and dense .

MIDAS ROCK
Hello?
NASA's interest seems to be a credible source of encouragement for the future of space mining in situ.
Peace and health,

Giant golden asteroid has enough heavy metals to make everyone billionaires – and Nasa is heading there in 2022

Unfortunately, if everyone is a billionaire....then no one is rich. The markets will just recalibrate and everything
(the divide between rich and poor) will continue as it is today.

Hmmm - really - so was this determined by proper random sampling & fire assays --- or - by XRF readout of another rock
Edit to add; - or as the guy near the end of the video said (after laughing) - "lets go explore it FIRST & see what it's made of"

They are unquestionable.
There is enough gold in the Earth to make everyone billionaires, if it could be found and extracted at low cost or free.
The metals in asteroids are probably not economical to mine for use on the Earth or possibly even the Moon. They might be useful if we make a massive colonization effort on Mars.

So you aren't wrong...but getting it back to the surface of the earth isn't as impossible as it may seem. When you don't have pesky people aboard a vessel, it doesn't need to be quite as soft of a ride. Keeping our blood circulating from the heart to the brain is the limiting factor right now.
From a technological standpoint, all we have worked on is getting the cargo there....not returning anything to earth except the people, data and light scientific instruments.
Supernova nucleosynthesis
https://en.wikipedia.org/wiki/Supernova_nucleosynthesisMy numbers only included the costs of transport. That's saying NOTHING about the cost of the equipment and actual mining costs. Plus the TIME it will take move so much material around in space over tens to hundreds of millions of miles.
THOSE costs I took a crack at trying to calculate at it was BILLIONS of dollars per ton. And again, that's assuming everything works perfectly every single time. It's simply unfeasible.
Mars almost certainly has its own metal deposits. And since its interior has cooled so much since it's such a small planet, we can drill much deeper into the crust without the issue.
And again, the heavy metals aren't going to be as important as construction metals such as iron, aluminum, titanium and even magnesium (used in many light-weight but strong alloys). Those are plentiful in all the rocky planets.
One planet that escapes attention is Mercury. It has a HUGE core of metal relative to its total size, almost no crust, a drastic day-night transition temperature that might make large heat engines a viable source of power, and permanently-dark polar craters with confirmed water ice deposits.
It would be a very valuable resource planet for massive space construction. Enough metal in its interior for a Dyson Sphere!

Energy..
A gold coin minted 1000 years ago is still going strong and can be said to be energy efficient.
A non noble coin can last 100s of years and is quite energy efficient.
A Banknote of paper last 10-15 years then it will be burned. not so energy efficient if not recover the energy
Any digital currency or crypto are depending of constant energy supply. If no energy then "Poff!"
Ps: Large space mining equals large energy needs and the earth will be covered by "valuable metals" with no space to live, acute energy deficit and the risk that a 12,5 Billion tons cargo ship, loaded with gold, crash land on your house. If it misses the house, and lands in the pool, the tsunami will kill us all.

I think its a highly realistic scenario that the gold standard comes back. The only thing needed is a distrust to currency and a wish for a stable resource based money system. Inflation is theft. Nothing else. When people understand this something will happened. In a gold based economy your gold gets more valuable by the time due to DEFLATION and there is not any major need to put it in the bank. Well, the banks hate this scenario and therefor oppose it.
... and that triggered the physicist in me.
The mass of Mercury is 3,30E+23 kg with roughly 70% metal and the rest silicates. We assume that it is in the form of a nickel - iron alloy and has a density about 8000 kg per cubic meter. This gives us about 2,9E+19 m3 of metal. If we spread it out as a Dyson sphere at the orbit of Mercury (5,75e+10 m mean) with an area of 4,15e+22 m2 we get a metal shell of 0,7 mm. If we build our shell at the orbit of the Earth then the shell would end up about 0,2 mm thick. That's just twice the thickness of an aluminium can.
I believe that the possibility of building a Dyson sphere from the material contained in the solar system is about as probably as one of the Euro zone countries going back to a gold standard backed currency before world war three begins.
For anyone that think I'm wrong, I have a 50 gram gold bar that I would trade for Euro, dollar or Swedish kronor at spot price. Offer valid until I move to a Dyson sphere.

The more updated ideas regarding Dyson spheres is that they wouldn't be solid shells, but more of a lattice structure with flexibility. That would tremendously decrease the amount of materials required, and negate the need to deal with the enormous heat and radiation build up inside if it was a sealed structure.... and that triggered the physicist in me.
