In the past few days, Tongbai County, Nanyang, Henan Province, has caught fire on the Internet, because according to the experts of the Henan Geological and Mineral Bureau, they have found a very large gold mine there.
Geologists have discovered a total of 16 gold ore bodies in the area of Weishan City in Zhuzhuang Town, Tongbai County, roughly estimating that the gold reserves in this area are 31.55 tons, and when more detailed exploration results come out at the end of the year, the gold reserves will exceed 50 tons.
As soon as this news came out, the whole network began to inquire whether the villagers there had picked up dog head gold or golden sand, which is commonly known as gold knots or dog head gold, because there had been news that Henan villagers had picked up gold knots in the river near the gold mine, and some people in Hebei had even picked up dog head gold in the coal pile.
So far, however, no one seems to have actually found gold in the area of Weishan City in Zhuzhuang Town, and geologists have concluded that there are gold mines here, relying on rock sample analysis, rather than hearing that someone here has picked up dog head gold.
In fact, dog head gold or gold lumps, from the scientific analysis is the element of gold in nature, which may have some other impurities, but gold elements are definitely the majority.
In the eyes of astronomers, all the gold on the earth actually comes from the supernova explosion in the universe, because the universe only has hydrogen and helium at the beginning, only after they form stars, the high temperature and pressure inside the star will turn hydrogen into heavy elemental materials such as gold, silver, copper and iron, and finally spread these heavy elements into space through supernova explosions or neutron star mergers, and our solar system is a typical example.
After the birth of the sun from the nebula containing heavy elements 4.6 billion years ago, the remnants of the heavy elements formed the eight planets of the solar system as we know it, and even the heavy elements that make up our own human beings were born at the moment when the sun formed 4.6 billion years ago, so in essence, we are the children of the stars like the sun and the earth.
The gold hidden in the depths of the earth's strata is gradually rising to the near surface area in geological activities, so whether it is the newly discovered giant gold mine in Henan or the gold mine that has been mined in various countries before, in fact, each ton of gold mine can only extract a few grams of gold.
Internationally, if the weight of gold that can be extracted from a ton of gold ore exceeds 5 grams, then the gold mine is even if the output is very high, and the average gold mine can only extract 3 grams per ton, when a gold mine can only extract 1 to 2 grams of gold in a ton of ore, the mining cost of the mine will exceed the revenue, and the mine will be abandoned.
When the former Soviet Union drilled the Kola ultra-deep borehole, it was found that the gold storage density deep in the formation was much higher than the surface, but the mining there was too difficult, so it was later lost.

The surrounding villagers failed to pick up the dog head gold this time, probably because the formation time of this gold mine is not long enough, so the gold element that fell off from the gold mine has not yet had time to precipitate step by step to accumulate into a gold lump, but if there is a river or stream near the gold mine, it is very likely that there will be gold sand or gold grains in the river sand.
Through the geologists' research on dog head gold, this kind of natural gold lump distribution that can be clearly seen is extremely rare, often hundreds of thousands of years of precipitation can be shaped, so if someone finds that they have picked up dog head gold, the best result is still handed over, for scientists to use for research, rather than artificial smelting into gold jewelry, because the history of dog head gold precipitation for hundreds of thousands of years is far more valuable than gold itself.

Every planet in the universe is actually a treasure trove of rare metals of gold, and this little bit of metal resources on earth is still being grabbed, and when it comes to the era of space mining, the minerals on a random asteroid are worth tens of billions or even hundreds of billions of dollars.
Some of the large celestial bodies located in the asteroid belt, such as Residing, are worth as much as 10,000 trillion US dollars, because it is all on it is iron, nickel, gold, silver, platinum and other precious metals, if aliens buy it, all mankind can get 93 billion US dollars per person.
