Gold facts/information Quote then add your facts

A cubic centimetre of gold weight 19.3 grams

A cubic inch weight is 10 ounces

Gold is Au and silver is Ag

Atomic n° of gold is 79 (Au79)

Silver is a better conductor of heat and electricity than gold but gold does not oxidize.

Gold is soft, dense, malleable, ductile

Gold is malleable enough for just 1 gram to be hammered into a sheet 1 square meter in size.

The melting point of Gold is 1,064.43°C (1,947.97°F).

100% of gold found naturally is isotope Au-197.

 187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons)

 gold is “diamagnetic”, meaning that it can be repelled by a magnetic field, but cannot form a permanent magnet.

United States. Tonnes: 8,133.5 in 2020

China. Tonnes: 1,948.3

The first Gold coins appeared around 700 BC.

An ounce  can be beaten out to 187 square feet (about 17 square metres)

 1870s until World War I the gold standard was the basis for the world’s currencies. 

Gold was the international monetary system, it came to an end by the 1970s

Gold occurs mostly in the native state, except with telluriumselenium, and bismuth

I think the above is what happened to this one.  Looks like a 3 oz'er to only come in at 1.3 ozt.  Still a momentous recovery for that area and the person who dug it.

Find a profitable way to concentrate that and get mighty rich! 🤑

Let's take the lower bound of GotAU's calculation since the 4-27 mircrograms of gold per cubic meter of seawater appears to be a range of measurements and we don't know the world average -- somewhere in that range presumably.  Now, divide that by the amount of gold recovered to date (estimate in Geof's post) and we find that there is at least 30 times as much gold in the Earth's oceans as has ever been recovered (from the land).

However, that's still a drop in the bucket compared to what is still deep in the earth -- at least 4x10^18 g, 4 followed by 18 zeroes or four quintillion grams.  That's 100,000 to a million times what GotAU's calculation says is in the oceans.  (Calculated based on the mass of the earth's mantle times the [conservative] fraction of gold in the earth's crust; thus I'm assuming mantle and crust have similar compositions which might not be true.)

It's a bit surprising to me that the Netherlands and Iran are ranked that high. I would have thought Canada, Mexico, Brazil, Australia,and South Africa would be higher.

Check this site out Gold In the world visualized

That page (and site) have fantastic graphics.  A few clarifications:

1) the gold depicted in the photo Steve posted is what governments hold.  According a later graphic on that page it's only between 17% an 18% of all the gold in possession.

2a) although it's true that in 1933 it was made illegal to own gold bullion (kept in the USA, see below) and each person was limited to $100 face value in gold coins, the possession of gold in jewelry form was allowed, and jewelers were excepted (presumably within limits) on owning bullion for the purposes of making jewelry.

2b) a loophole(?) was stepped through by owning gold kept offshore (mostly housed in Europe, especially Switzerland).  Recently much of that gold which was in the form of USA coins (especially $20 gold pieces) has been returning to the USA and is being sold to numismatic collectors.  If you've ever watched Rick Tomaska's cable TV show (on Rare Collectibles TV) you'll have seen many presentations where he discusses acquiring some of that and subsequently sells cherry picked high grade specimens to viewers.

2c) the USA government kept close records on how much gold (in the form of coins) they melted, broken down by denomination.  A graphic shown occasionally on the above mentioned show indicates that less than half of any single denomination ever minted by USA was melted, before and after the 1933 buyback.  (I think they melted all coins in their possession, including recovered from the so-called 'confiscation' buyback.)  So there is still quite a bit out there, somewhere....

A big question for detectorists is "how much has been lost/hidden awaiting our detectors to sound off over them?"  (That's not explcitly shown in the graphics Steve linked to.  😁)

So, that four quintillion grams of gold on Earth, divided by 7.7 billion people means that our shares are over 518 million grams each?!  Well come’on, lets go!! 🤪

We're gonna need more than plastic scoops to reach it.  (Sorry, Gerry, if I just killed a mad rush on sales.)  Even these Russians only got down a bit over 12 km of the 2900 km thickness (crust + mantle) and it took them 19 years to do that!

      From Kitco News.  www.kitco.com
      Perth Mint sees record demand first-quarter demand for gold bullion

       
       
       
       
       
       
      (Kitco News) - Mints worldwide are seeing unprecedented demand for physical bullion, with the Perth Mint the latest to announce record sales for the first quarter of 2021.
      In a blog post published Tuesday, the Perth Mint said 130,000 troy ounces of gold and almost 1.6 million troy ounces of silver shipped to clients worldwide in March.
      “These figures are 285% higher (gold) and 178% higher (silver) than average monthly sales dating back to 2012,” the mint said in the commentary.
      In the first quarter this year, the Perth Mint sold more than 330,000 ounces of gold and more than 4.5 million ounces of silver, said Jordan Eliseo, manager of listed products and investment research at the mint, in the report.
      “These figures represent the highest calendar quarter on record for gold and the fourth-highest calendar quarter on record for silver,” he said.
      General Manager Minted Products Neil Vance said that the most popular bullion coins at the Perth Mint are the one-ounce Kangaroo coins.
      “The market continues to take everything we can make at present,” he said.
      The historic demand for gold and silver comes as both precious metals saw sharp declines since the start of the year. The mint noted that gold prices fell 11% and silver prices dropped 9% in the first three months of 2021.
      “There have been multiple factors contributing to the sell-off, which has now seen the U.S. dollar gold price pullback by almost 20% since it hit all-time highs in August 2020,” the mint said.
      Resilient strength in the U.S. dollar, rising 10-year bond yields, growing competition from cryptocurrencies and record valuation in equity markets are all competing against the gold market, the Perth Mint said.
      The strong demand for bullion comes as the Perth Mint continues to battle it out with social media and Reddit users who are encouraging investors to run on the mint and create a physical short squeezing. Reddit users have accused the mint of not having enough physical silver.
      The Perth Mint said that it has plenty of supply, but it takes time to refine the metal into its popular products.
      “While we just about satisfied demand for gold this month, interest in silver is outstripping our capacity to convert plentiful supplies into finished goods,” said Vance.
      The data from the Perth Mint is also in line with global demand trend. Data from the U.S. Mint shows that it sold 412,000 ounces of gold in the first quarter of 2021, its best start since to the year since 1999.

      I'm having a discussion with an engineer friend about gold.  I am of the contention that there has been much more gold mined and found than what is reported.  Well ... what is my starting report?  Let's go with this one as I don't really know how to prove or disprove my assumption.  I don't want this to be 'consensus science' which is in vogue right now but I guess without true gold facts there has to be a certain amount of belief in known gold produced each year and reserves in conjunction with industrial and aesthetic uses over all time on earth.  I don't really care about how much is left or not mined or in reserves.
      I found this statement when I did a Google search:
      Between all of the gold sources in the world, current estimates suggest that roughly 2,500 to 3,000 tons of new gold is mined each year. At present, experts believe that the total amount of above ground gold in the world stands at just over 190,000 tons.   The source of this statement is Provident Metals.   Is this over or under?   If this topic has been done please point me to the thread and we can delete this one.

      This is the title of a book about producing gold in WA.  I've just read a review of the book and think the book would be a good read.  It appears now because a company is about to begin production.  I don't own any Australian gold stocks but maybe I should.

      Have you ever wondered about gold mining on the Russian/Chinese border?  This is quite a story.  Use your imagination and it is probably worse!  What men will do for gold.
