Chapter 512 Gold Mine

Both Chen Ran and Yang Shijie imagined this cave as a mysterious treasure place before, especially when Chen Ran had read the letter left by the man in the black room. In the letter, the man in the black room has been emphasizing that there is some shocking secret hidden in this mysterious place, plus the mysterious stone in his pocket, so that Chen Ran also Imagine this place as either hiding a large amount of treasure or a cave hiding a dangerous place like Ghost Bear Ridge. In short, the imagination is a little fantasy or fantasy. Although Yang Shijie's imagination is different from Chen Ran, it is also an interest. Although he doesn't know what the man in the black room said, The Japanese bones seen along the way also guessed that this place was a thrilling place. When they arrived at this rock cave, they saw the dense caves surrounded by large and small caves. At that time, they imagined that so many holes were likely to be the suspense left by the owner of the cave. At that time, the two were stunned. That's why, however, after seeing the debris piled up on the ground, they suddenly reacted...

What is this suspense? It is clearly...

A mine.

Yes, this rock cave is simply an abandoned mine.

This can be seen from the environment in the rock cave in front of us and the messy baskets on the ground and some simple tools.

I don't know that there are more or less black ores in several baskets.

This result stunned both Chen Ran and Yang Shijie. Obviously, they didn't expect this place to be an abandoned mine, and the cave they just entered was just a channel for mining stones from the mine, and it was obvious that this mine was not a modern product. At least for more than 60 years.

Knowing that this cave is a mine, Chen Ran is quite strange. After all, this is his fellow villager. Although he has not lived in his hometown for a long time, most of his childhood memories are still there, especially this "back mountain" in the village. Even if he has never been to this place, his grandfather and the people in the village are willing to I have decided to go to this place or pass by here, but for so many years, no one has found that there is such a mine under this mountain. This feeling is like suddenly found something that I don't know in my most familiar territory.

Of course, Chen Ran just sighed for a moment, and then was relieved. Think about the earliest Tang Dynasty mine site in Shangrao, Shanxi Province, was also discovered the year before last? In ancient times, mining was not as much as it is now.

I just don't know what mine this mine is?

When he was stunned, Chen Ran had bent down and picked up a piece of ore that fell at his feet. Although it was more convenient and accurate for him to directly release energy aperture detection without bending down at all, in fact, he still liked to see it with his own eyes when he could see it with his eyes. For no other reason, he was just used to it.

When Chen Ran picked up a piece of ore and observed it, Yang Shijie also reacted and quickly focused the high-blazing light on the ore in Chen Ran's hand.

The ore in Chen Ran's hand is dark on the surface and looks a little like a coal mine, but it is not as smooth as a coal mine or iron ore. It feels a little astringent, like a small pimple and a small pimple.

Chen Ran looked over and over with the light in his hand and Yang Shijie's hand, but the ore was black and could not be seen from the surface.

Unable to see it, Chen Ran also wanted to detect it with the energy aperture, but before he released the energy aperture, he suddenly noticed a flash of gold wire.

"Is this still a gold mine?"

Chen Ran's heart suddenly moved, stunned for a moment, and quickly looked over. At this glance, he really saw a gold wire. This gold wire is not very eye-catching. If you don't look carefully, you really can't find it.

Chen Ran saw this gold wire, and Yang Shijie obviously saw it. He was stunned and suddenly became surprised: "Gold mine?"

Chen Ran did not answer Yang Shijie's question, because at this time, he had not hesitated to release the energy aperture into the interior of the ore.

"What a gold mine!"

A little gold in his eyes suddenly made Chen Ran laugh happily. Although even if a gold mine is found, this gold mine may be just a waste mine, or it may be a small mine that is not worth mining at all. Even if a gold mine is found, it is not his own, but this kind of unexpected joy But it is incomparable.

I'm afraid every Chinese will feel this way when he meets it. Even if he is a multimillionaire or even a billionaire, of course, he doesn't know how he will behave after being happy.

Yang Shijie was obviously no exception. At this time, he also showed a trace of excitement and was surprised to shine other ores on the ground with a high-blazing lamp.

Although Chen Ran was happy for a moment, he was not happy. He was only happy to find the instinctive joy of the gold mine. After being happy, he observed the gold mine with curiosity.

To be honest, whether it is a jade mine or a gold mine, Chen Ran has rich theoretical knowledge, but he has never seen it. Not to mention the gold mine or the jade mine, he has never been to the mine site to explore.

"The taste is so high!!!"

Chen Ran also took a searchlight and shined around, but obviously couldn't see anything from the surface of the mine. Therefore, after looking at it, he released an energy aperture to explore, but what he first explored was the underground of the rock hole. When the energy aperture was detected more than one meter into the ground, there was nothing. Now, but when it was almost two meters deep, my eyes suddenly lit up, and then I felt as if I had entered the golden ocean, only as if my eyes were shining on Venus, and my eyes were full of gold.

After being surprised, Chen Ran quickly explored the rock hole carefully with an energy aperture. The results of the detection really surprised him and pleased him.

Although the other places he detected are not as high as the gold ore underground as the rock hole, it is also high, and on average, it is estimated to have 70 or 80 grades.

pin wei refers to the gold content of a gold ore, usually expressed in g/t per ton, and generally 1g/t is commonly used as the boundary grade.

The scale of ore deposits, ore mining, difficulty of beneficiation and other factors vary according to different types of ores, and the cost is also different. A ore body larger than 1g/t can be used as an industrial ore body, and its development cost is comparable to profit. However, over the years, with the continuous rise of gold prices, now even 0.5g/t or even Gold mines of 0.3g/t or 0.25g/t grade can also be mined. Of course, it depends on the location and how high the purification technique can reach.

Generally speaking, a gold mine with a grade of more than 3g/t is a medium-grade gold mine, while a gold mine with a grade of more than 10g/t is a high-grade gold mine.

Of course, this is only a relative statement, and there is no mandatory regulation.

Because gold mines in China are generally of low grade, there are few high-grade gold mines. General gold mines can reach between 1g/t and 3g/t, which is good, and most of them are of this grade.

Why Chen Ran detected so high is because he only explored this piece of gold ore. Naturally, the grade of a gold mine has high and bottom. Generally speaking, the gold mine grade is the average grade of the whole gold mine. As for how high the grade of this gold mine is, it depends on other places. .

However, judging from the situation of Chen Ran's exploration, the grade of the ore body he explored should never be low, and after his and Yang Shijie's observation, it was found that the mine had not been mined much. It should have just been surveyed. As for why there was no large-scale mining after the survey, it is unknown. The reason is that something suddenly happened and they withdrew before they could mine it. After all, in ancient times, it was not as developed as the current information. Or maybe they encountered the same experience as the Japanese, and the whole army was destroyed here.

As for what kind of experience these Japanese troops encountered and what kind of shocking secrets they found, Chen Ran has not found any clues, and he has not noticed the breath of the black stone.

The reason why he chose to explore this mysterious place at this time is that Chen Ran thought that even if this place was not buried with some big secret, it might be a batch of treasures buried, but he never thought that the treasure was not seen, but the gold mine saw one.

Although the gold mine is also a treasure, even if he finds it, it is not his, but the country's. It's obviously not impossible to secretly mine, but it can't satisfy him. If there is less mining, it's not enough money. If there are more, something will definitely happen to him.

* Mining is undoubtedly also very troublesome. * It is not easy to do, and the cost of mining is also extremely high. It can only be said that everything depends on the storage capacity of this gold mine now.

Of course, since this gold mine has been found, it can't be thrown away in vain. Even if you don't mine it yourself, you have to get the right of survey first.

After exploring the * mine, Chen Ran thought nonsense for a while. When he saw Yang Shijie fiddling with two rifles, he looked at it curiously, but he really didn't know much about this, so he could only watch the fun.

These little Japanese good things have not been left, but there are a lot of weapons left, at least hundreds, but they are all rusty and don't know if they can be used. If they can be used, it's good to use them as shotguns.

The echo in the mine was too big, and Chen Ran and Yang Shijie were still wearing gas masks. Therefore, the two could not talk without talking. Seeing Chen Ran coming over, Yang Shijie handed the rifle in his hand to Chen Ran and deliberately pointed to the bayonet in front of the rifle, which means that the bayonet could be used.

Chen Ran took the rifle and pointed to the hole with a faint light on the left, signaling to go out of the hole to have a look.

Yang Shijie nodded and walked over with a probe lamp in one hand and a rifle with a bayonet in the other. Chen Ran also followed.

This hole is the most spacious hole, which is enough to allow five or six people to pass side by side. At first glance, it is the exit of this mine, but the hole is a little low. Chen Ran and Yang Shijie have to bend down when they pass through, and there are also many skeletons in this mine. The skeletons here are a little messy, unlike The hole they passed before was so intact, which made Chen Ran and Yang Shijie wary.

After walking about dozens of meters, the rock hole suddenly turned in a direction, and the air blowing at this time became fresher and fresher. Chen Ran took off his gas mask.

After turning this corner, the light suddenly lit up, but the cave became lower and lower.

"It's over."

Seeing this, Yang Shijie turned around and reminded Chen Ran. Seeing that Chen Ran took off the gas mask, he also took it off.

Chen Ran nodded, and then sucked his nose. He didn't know where it was in front of him. There was a faint smell of medicine and a fragrance, and it also gave him a very comfortable feeling. This feeling seemed to be the opposite of the black stone in his pocket.

Both Yang Shijie and Chen Ran were obviously a little curious about where the front was. Therefore, they accelerated the speed of moving forward a little, and after crossing about 30 meters away, the two finally reached the end smoothly.

When Chen Ran followed Yang Shijie out of the rock hole to see the scene in front of him, he was stunned.
