Henan Provincial Bureau of Geology and Mineral Resources came good news, China Henan Nanyang Tongbai County Zhuzhuang Town Weishan City area found a very large gold mine, a total of 16 gold ore bodies found, the preliminary estimate of gold reserves should be 31.55 tons, by the end of the year is expected to exceed 50 tons.
In fact, Henan actually stores a lot of gold mines, and there were once villagers in the creek near the gold mine to pick up the "dog head gold", dog head gold is also called natural gold, although it is not pure gold, but more expensive than the price of pure gold, once a Hebei man bought a pile of coal for winter heating, it turned out that there was an unusually hard stone in his coal, which could not be smashed by a hammer. After testing, it was found that this was dog head gold, although the weight was only 1.045 kg, but the estimated value reached tens of millions of yuan.
Henan villagers once picked up a dog head gold in the area of Funiu Mountain, although the dog head gold was only 964.5 grams, but the pure gold content reached 93%, which is a very rare and precious type of dog head gold.
According to experts, if you explore the place where the dog head gold is found, you can generally find gold mines. So the question is, now that a very large gold mine has been found in the area of Weishan City in Zhuzhuang Town, Tongbai County, Henan Province, can dog head gold be found near this gold mine?

We know that gold is an element, and that the conditions for its formation are very harsh, requiring supernova explosions or neutron star mergers to occur, and fortunately there was such a phenomenon near the Earth before the formation of the Earth.
At the beginning of the formation of the earth, although gold already exists, but the density of gold is larger, and the beginning of the formation of the earth is also called the molten state, so that a large amount of gold sinks into the interior of the earth, so the gold reserves inside the earth are very rich, and the gold reserves on the surface of the earth are not much.
However, the Earth's plate movements are very active, and some of these geological movements are able to bring large amounts of gold to the Earth's surface, so gold deposits will form here.
Of course, not all gold mines have mining value, and some gold mines have a low gold content, for example: 1 ton of ore has only 1 gram of gold content, there is no mining value. In fact, there is also a gold mine with reserves of 5 tons in the Funiu Mountain area of Henan, but it is not mined because the gold content is low and does not have mining value.
In fact, most of the gold mines with mining value are also very low in gold content, such as: the Gray Jiabao Gold Mine in Zhenfeng County, Qianxian Prefecture, can only extract 3-5 grams of gold per ton of gold ore. Each ton of ore contains more than 5 grams of gold is enough to be called rich ore. Of course, the way to obtain shajin is relatively easy, so in ancient times, people mainly mined shajin.

In fact, not all gold mines will have dog head gold nearby, which is mainly related to the formation of dog head gold.
Dog head gold is generally found in the downstream section of the gold mine, the gold in the gold mine, when it is processed by flowing water, will be separated from the stone, and then brought into the downstream river, this part of the gold is also called "sand gold", which in the flow of water drop is small, gradually open and gentle area, sand gold will usually gather here, forming a sand gold enrichment area, which is usually the place where gold prospectors pan for gold. (In areas with large drops, the water flow is too fast, and it is difficult for sand gold to gather, so it is difficult to pan for gold here.)
Under a specific pH and a specific temperature, the gold in the water will continue to precipitate together, and the surrounding quartz, natural silver, natural copper, etc. will gather and form, and more and more, and eventually form "dog head gold".
In fact, the formation of dog head gold is very slow, and the longer the larger the dog head gold is formed, the general dog head gold needs hundreds of thousands of years or even tens of millions of years of accumulation to be able to form. Therefore, the larger the head, the higher the purity of the dog head gold is more expensive.
In fact, the value of dog head gold can not be measured only by the value of gold, because it is pure natural and can not be copied, so the value of dog head gold is much more expensive than the same quality of gold, so picking up dog head gold and melting it into gold is actually the behavior of "buying and returning pearls".
Seeing the formation process of dog head gold, you will find that the formation conditions of dog head gold are very harsh, both nearby gold mines and water need to flow through the gold mining area, but even so, it does not mean that dog head gold will be formed, so there is no dog head gold near the super large gold mine found in Zhuzhuang Town, Tongbai County, Henan Province, and no one dares to pack tickets.

Although dog head gold will be found near the gold mine, this does not mean that dog head gold will inevitably form near the gold mine. The formation conditions of dog head gold are very harsh, but it is precisely because of this that dog head gold is so rare, lower than the probability of winning the lottery.
Another value of dog head gold is scientific research value, in addition to having gold properties, it can also help scientists study local gold mines, as well as other associated mines, etc., so in many geological museums, there will be dog head gold exhibits.
