Chapter 509 Gold Mine

Both Chen Ran and Yang Shijie had imagined this cave as a place of mysterious treasures before this, especially Chen Ran had read the letters left by the man in the dark room, in which the man in the dark room had been emphasizing this mystery There are some shocking secrets hidden in the land, and the mysterious stone in his pocket, so that Chen Ran imagined that this place either hides a large treasure, or hides a cave like Guixiongling. Dangerous place, in short, the imagination is a bit fantasy or fantasy, and although Yang Shijie's imagination is different from Chen Ran's, it is also an interest. Although he doesn't know what the man in the black room said, but from the way Seeing the skeletons of the Japanese army, they also guessed that this place is a dangerous place. When they arrived in this rock cave, they saw densely packed caves of various sizes around the cave. The suspense left by the owner who dug the cave. At that time, the two were stunned because of this. However, after seeing the sundries piled on the ground, they suddenly reacted...

There is no suspense here, it is clearly...

a mine.

Yes, this rock cave is an abandoned mine at all.

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

Don't you know, there are more or less black ores in the baskets.

This result made both Chen Ran and Yang Shijie startled, obviously they did not expect this place to be an abandoned mine, and the cave they entered just now was just a passage dug in the mine for mining ore. And it is obvious that this mine is not a modern product, and it has been mined for at least 60 years.

Knowing that this cave in the rock is a mine, Chen Ran was quite surprised. After all, this is his hometown. Although he didn’t live in his hometown for a long time, most of his childhood memories are still there, especially the people in the village. This "back mountain", even if he has never been to this place, then his grandfather and people in the village must have been to this place or passed by here, but after so many years, no one has discovered that there is a place under this mountain range. There is still such a mine, this feeling is like suddenly discovering a place that I don't know in the most familiar territory.

Of course, Chen Ran just sighed with emotion, and then he was relieved. Thinking about the earliest discovered mine site of the Tang Dynasty in Shangrao, Shanxi, wasn't it also discovered the year before last?Mining ore in ancient times was not as grand as it is now.

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

When he was in a daze, Chen Ran had already bent down and picked up a piece of ore that had fallen by his feet. Although it was more convenient and accurate for him to directly release the energy aperture to detect it without bending down, he could actually see it with his eyes. When he was young, he still liked to see with his own eyes, for no other reason, just getting used to it.

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

The ore in Chen Ran's hand is black on the surface, it looks a bit like a coal mine, but it is not as smooth as a coal mine or an iron ore. It feels a bit rough to the touch, like a small pimple. land.

Chen Ran looked over and over through the lights in his own hand and Yang Shijie's, but the ore was so dark that nothing could be seen from the surface.

Unable to see it, Chen Ran thought about using the energy aperture to probe in and check it out, but before he released the energy aperture, he suddenly noticed a golden thread.

"Is this still a gold mine?"

Chen Ran's heart moved suddenly, he was startled for a moment, and then quickly looked over, this time he really saw a golden thread, this golden thread is not very eye-catching, if you don't look carefully, you really can't find it.

Chen Ran saw the golden thread, and Yang Shijie obviously saw it too. He was startled, and suddenly became surprised: "Gold mine?"

Chen Ran didn't answer Yang Shijie's question, because at this moment, he had released the energy halo without hesitation to penetrate into the ore.

"It's really a gold mine!"

A little bit of gold caught his eye, which immediately made Chen Ran laugh happily. Although even if a gold mine is discovered, it may be just a waste mine, or it may be a small mine with a small amount that is not worth mining, or even a gold mine. Even if he discovers a gold mine, it is not his own, but the feeling of unexpected joy is incomparable.

This point, I am afraid that every Chinese will feel this way when they meet, even if he is a multi-millionaire, or even a billionaire, of course, I don’t know how he will behave after he is happy.

Yang Shijie was obviously no exception, but he also showed a little excitement at this time, and was surprised to shine on the other ores on the ground with a high incandescent lamp.

Although Chen Ran was happy for a while, he didn't get carried away with joy. He was just the instinctive joy of discovering the gold mine. After he was happy, he began to observe the gold mine with curiosity.

To be honest, whether it is a jade mine or a gold mine, Chen Ran has a wealth of theoretical knowledge, but he has never seen it, not to mention a gold mine, even a jade mine. He has not been to the mine site to investigate.

“The taste is so high!!!”

Chen Ran also took a searchlight and looked around, but it was obvious that nothing could be seen on the surface of the mine. Therefore, after looking at it, he released an energy aperture to investigate, and he The first thing to explore was the underground of the rock cave. When the energy aperture probed into the ground for more than one meter, nothing was found, but when it was almost two meters deep, it suddenly lit up, and it seemed that it had entered the gold' As if in a sea of ​​color, I just feel as if my eyes are staring at Venus, and my eyes are full of gold.

After being surprised for a while, Chen Ran quickly used the energy aperture to detect the rock hole carefully, and the result of the detection really surprised and delighted him.

Although the other places he detected were not as high-grade as the gold ore underground in the rock cave, they were still considered high, and the average grade was estimated to be seventy or eighty.

The grade refers to the gold content of a ton of gold ore, usually expressed in grams per ton of gt, and 1 gt is generally used as the cut-off grade.

Ore deposit scale, ore mining, dressing and smelting difficulty and other factors vary depending on the type of ore, and the cost is also different. Ore bodies larger than 1 gt can be used as industrial ore bodies, and their development costs are equivalent to profits. However, with the price of gold over the years Now, even gold mines with a grade of 0.5gt or even 0.3gt or 0.25gt can be mined. Of course, depending on the location, it depends on how high the purification technique can reach.

Generally speaking, a gold ore whose grade can reach 3gt or above is considered a medium-grade gold mine, and a gold mine that reaches 10gt or above is a high-grade gold mine.

Of course, this is just a relative statement, and there is no hard and fast rule.

Because the gold mines in our country are generally low-grade, there are very few high-grade gold mines. The general gold mines can reach between 1gt and 3gt, which is not bad, and most of them are of this grade.

The reason why Chen Ran’s detection is so high is because he only detected this piece of gold ore. Naturally, the grade of a gold mine has a high place and a low place. Generally speaking, the gold mine grade refers to the entire gold mine. The average grade of the gold mine, as for how high the grade of this gold mine is, it depends on other places.

However, judging from Chen Ran's exploration situation, the grade of the ore body he explored should definitely not be low, and after his and Yang Shijie's observations, it was found that this mine has not been mined much, it should have just passed the investigation That's all, as for why large-scale mining was not carried out after the survey, I don't know the reason. Maybe something happened suddenly and they withdrew before they could mine. After all, in ancient times, the information was not as developed as it is now. Perhaps it was because they encountered the same experience as the Japanese, and the entire army was wiped out here.

As for what kind of experiences these Japanese soldiers encountered and what kind of shocking secrets they discovered, Chen Ran hadn't found any clues yet, and he hadn't noticed the aura emanating from that black stone either.

The reason why he chose to investigate this mysterious place at this time is that Chen Ran thought that even if there were no big secrets buried in this place, there might be a batch of treasures buried there, but he never thought that the treasures were missing. Mine did see one.

Although the gold mine is considered a treasure, even if he finds it, it is not his own, but the country's. It is obviously impossible to mine it secretly, and it is not impossible, but it is just that the secret mining cannot satisfy him. If there is less mining, it is worth it. The money is not enough for him to trouble, if there is too much, something will happen.

It is undoubtedly very troublesome to obtain a license for mining. Not to mention that it is difficult to obtain a license, and the cost of mining is also extremely high. It can only be said that everything depends on the size of the gold mine.

Of course, since this gold mine has been discovered, it can't be thrown away for nothing. Even if you don't mine it yourself, you must first get the right to survey it.

After investigating in the first mine, Chen Ran thought wildly for a while, and seeing Yang Shijie fiddling with two rifles, he went over to have a look curiously, but he was really interested in this If you don't know much, you can only watch the excitement.

These little good things were not left behind, but there were quite a few weapons left, at least a few hundred, even if they were all rusty, I don’t know if they could be used. If they could be used, it would be good to use them as shotguns.

The echo in the mine was too loud, and Chen Ran and Yang Shijie were still wearing gas masks. Therefore, the two of them could not talk without talking. Seeing Chen Ran approaching, Yang Shijie handed the rifle in his hand to Chen Ran One, and specifically pointed to the bayonet in front of the rifle, which meant that the bayonet could be used.

Chen Ran took the rifle over, pointed to the hole on the left where there was a faint light, and motioned to go out and have a look through the hole.

Yang Shijie nodded, and walked over with a searchlight in one hand and a rifle with a bayonet in the other, and Chen Ran followed.

This hole is the most spacious one, enough for five or six people to pass through side by side. At first glance, it is the exit of the mine, but the hole is a bit low. When Chen Ran and Yang Shijie pass through, they have to bend over. , and there are also a lot of bones in this mine, the bones here are a bit 'messy', not as complete as the hole they passed through before, which made Chen Ran and Yang Shijie vigilant.

After walking forward for tens of meters, the rock cave suddenly turned in one direction, and the air blowing in at this time became more and more fresh. Chen Ran took off the gas mask.

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

"It's over."

Seeing this, Yang Shijie turned his head and reminded Chen Ran. Seeing that Chen Ran took off the gas mask, he took it off too.

Chen Ran nodded, and then sniffed again. He didn't know where it was in front of him, but there was a faint smell of 'medicine' and a scent, and it gave him a very comfortable feeling. , this feeling seems to be the exact opposite of what the black stone in his pocket gave him.

Both Yang Shijie and Chen Ran were obviously a little curious about where the front was, so they sped up their walking speed a bit, and after passing through about 30 meters away, the two finally reached the end smoothly .

When Chen Ran got out of the rock hole and saw the panorama, he was stunned.
