The Book of Appreciation

The mine in front of Wu Di is about 15 meters deep, and it is a mixed mine of gravel and sand.The proportion of the rough jadeite seems to be pretty good. When walking down the slope by the side of the pit, you can even see the woolen material directly on the side of the pit.

"This should be the first layer. After comparing multiple mine pits and sampling, we determined that the location of this layer is ten meters from the ground, and the thickness is more than half a meter. According to the scope of sampling, the area is very wide. In this case, it is only There should be thousands of tons of rough jadeite in this layer."

The engineer introduced as he walked.

"Actually, for this emerald mine, the price of 5000 million yuan is low, because the value of the proven reserves is more than [-] million U.S. dollars. In Guatemala, the history of emerald formation is even longer than that of Myanmar, so the ore layer should be More, some mines have detected even close to ten floors!"

Wu Di didn't speak all the time. He was on the top of the mine just now, and he had already seen through it with his clairvoyant eyes. The emeralds in this mine were not even close to ten layers, not even two layers!In other words, except for the half-meter-thick layer of emerald ore exposed here, no matter how deep the other places are dug, there will be muck!

He searched in the mine for a while, but couldn't find the reason, so he looked directly into the distance.

That's right, there is only one layer in the vicinity of nearly a thousand meters, and the thickness is uneven, and the proportion of jadeite rough is relatively low.However, this should obviously be a secondary mine formed by alluvial deposits, how could there be only one layer?

Emerald mines are generally divided into primary mines and secondary mines.The primary ore is due to the high pressure and low temperature physical and chemical conditions caused by the strong subduction of the oceanic plate on the continental plate, which makes the mixed deposits melt and crystallize, forming various minerals or rocks, and then undergoes strong tectonic action (mainly fracture) The original rock is strongly broken, mixed with cr, fe, mn and other color-causing elements to dye and mix with the finely ground jadeite, and finally the finely ground jadeite is re-cemented and crystallized to form emeralds of various colors.

Secondary ore is mainly the ore deposit formed after the primary ore deposit was eroded, transported and deposited by rivers.Therefore, there are generally layers, and the characteristics of the original stones between layers are more obvious.For example, the old Pagan mining area has now been excavated to the fifth floor, and the external characteristics of each layer of jadeite rough are different.

Since this is a river valley, it should be a typical alluvial secondary mine, but why is there only one layer?

He took a look. There were three pits dug in this mine, each of which was about a kilometer apart. The selection of points was very reasonable. From the situation of the pits, it should be possible to make a rough assessment of the level of the mining area.

He greeted the accompanying engineer and walked to another pit more than 1000 meters away.

"This is a sampling hole. A total of 36 holes have been drilled in the mining area. This mark is a sampling hole for taking out emerald ore. This is based on the geological conditions to judge that there may be ore, but this is not."

The engineer walked all the way and pointed to some bucket-thick round holes passing by.Wu Di took a careful look at each of them. The more he looked, the more confused he became. Could it be that this mine is an emerald mine with only one layer of emerald deposits?

The same is true for the second mine pit, and the same is true for the third mine pit. After Wu Di walked through the three mine pits, he has seen through the entire mine area. This is a pseudo-alluvial mine with little development value and only a layer of emerald deposits in some places. .

"Excuse me, have you ever dug emeralds in deeper places?"

The engineer nodded,

"The deepest sampling point here reached 60 meters, the shallowest one was five meters, and most of the rest were between ten meters and 20 meters. The deepest sampling point found emerald ore at about 40 meters, and the remaining There are more than a dozen sampling points that have found rough stones, but they are all between 20 and [-] meters. So we judge that this is a rich emerald deposit, and you need to know the sampling hole..."

Wu Di waved his hand to stop his nagging, and said:

"Take me to the deepest sampling point."

The engineer led Wu Di for about a thousand meters, and came to the edge of the valley, where there was a bucket-like round hole with different markings from other places, so dark that the bottom could not be seen.

There is only one layer of emerald here, but this sampling point can actually take out the rough stone from a distance of more than 40 meters. Could it be that there is something wrong with his perspective eye?

He looked carefully and shook his head. The situation here is similar to other places, but for some unknown reason, a piece of ore was buried at a depth of 40 meters, and one of them might just be at the sampling position. The engineer who took the sample got it. I really don't know if it was his luck or misfortune.

This is an emerald mine, but unlike other alluvial mines, it is an ultra-thin mine that is only formed by alluvial deposits.

In other words, in the upper reaches of the river, there may be a place where there is a primary emerald mine. After years of river erosion, some emeralds were brought here along with the water flow and deposited.If this process lasts for many years, it is very likely that the emerald ore will be covered layer by layer, but this is obviously unlucky. After not washing for many years, the river will dry up or be diverted, so it is left behind. Such a thin layer.

Judging from the current situation, such a large river valley, let alone worth 200 million US dollars, even if it was sold to him for [-] million US dollars, he would not want it!

Wu Di verified it with the heavenly book, and the meager aura proved that the ore here is not only small in quantity, but also not high in quality, in other words, it has no mining value!

"Fifth brother, the mines here seem to be different from those in Myanmar. It seems that there are no semi-weathered belts..."

The robot cat has been running around with Wu Di, and seeing Wu Di's frowning, he couldn't help expressing his opinion.

"Hehe, of course it's different. In Myanmar, the secondary mines we see have been mined for a long time, and we can't see the characteristics. Only in the primary mines in the mountainous areas can we see mines that have not been mined, but the primary mines The characteristics are different from the secondary ore. The secondary ore in the valley is generally alluvial. It is a new mineral that is re-formed after the weathering of the primary mineral, so there will be no obvious semi-weathering of the primary ore. Bring it."

"Oh, this is a secondary mine formed by alluvial deposits."

"It's a pity, this alluvial deposit is not that alluvial deposit!"

Seeing that Doraemon and Sparrow are confused, Wu Di further explained:

"Alluvium, as the name suggests, is a mineral deposit deposited after being washed and weathered by river water, strong winds, etc. It is usually laid in layers in the river bed, and the most can reach more than five layers. But for some reason, there is only one Layers are gone, so there is no mining value."

"Oh, that means that woman lost her bet on the mine. Fifth brother, do you think she wanted to sell it because she knew about this situation?"

The sparrow also understood and made his own judgment.

"It's possible, but it doesn't look like it. You can see that her investment here is obviously intended to be mined by herself. It may be that there is a problem with capital turnover, so she wants to transfer it."

"We've all seen it clearly, only fools will buy it! I don't think there is any need to waste time here, let's go and find mines by ourselves."

Wu Di shook his head. No one can tell whether there are mines in such a short period of time. Judging the mines in a place requires a comprehensive judgment of various factors, and a conclusion can only be drawn by drilling and sampling.If they made a hasty judgment like this, they might offend that woman to death.Think about it too, if you don't have clairvoyant eyes, you can just look at it casually for an hour, and reject other people's hard work that took two to three years, or even more than ten years, and you won't be considered a talent trick!

Wu Di found the engineer just now and asked:

"Can the sampling machine here still work?"

"No problem, we specially arranged a few workers here, but we can only drill three holes for you for free."

"Oh?"

"If we drill a lot of sampling holes, the price may not be [-] million US dollars, but [-] million, [-] million or even more."

Wu Di laughed and said:

"It may also become 5000 million, 2000 million, or even worthless, isn't it?"

"Yes, yes, this is the charm of gambling mines, hahahaha."

This engineer is a pure technician, much cuter than Ivanova who hid in the office as soon as she came.

"I don't ask you to re-select places to take samples. How about digging deeper in the sampling hole where you found the emerald, and taking samples at 20 meters, 30 meters, and 40 meters?"

"No problem, but this is sampling after all. The area is too small. Even if nothing is taken, it cannot prove that there is no mine here. After all, one-third of the sampling holes here have taken out emeralds, and those few mines have all been dug out. Only emerald, this is the most convincing."

Wu Di nodded. What he said is very reasonable. If you can determine whether there is a mine based on the sampling hole, then there is no such thing as gambling on the mine. I heard that there are unlucky people who drilled hundreds of sampling holes in the rich mine. The rough stones that can prove the existence of mines have not been taken yet!

The next thing is to wait in boredom. Wu Di has already used the heavenly book to explore. Although he has not been able to accurately estimate the area covered by the heavenly book, at least three or four kilometers is no problem. That is to say, the surrounding area of ​​the mine is close to five kilometers. There is nothing to do inside.

Seeing such an obvious bonanza, Wu Di actually wanted to take a sample, Ivanova couldn't help stabbing him a few more times, and directly summoned a helicopter to go back to the city to rest.Anyway, you all brought your luggage, so stay at the mine for two full days, and then I will pick you up again.

Seeing the helicopter take off, Sparrow raised his eyebrows,

"Fifth brother, I asked. It takes at least 20 minutes to drill one meter down. There are few of them, so they come one by one. The three sampling holes will take at least two days. How about..."

"Hehe, why don't you leave someone here to watch? Or can they fool us casually? Besides, if you want to buy mines, but you don't watch from the side, isn't there a problem when you look at it?"

The sparrow looked at the doraemon and then at himself, stretched out a fist,

"Come on, divergent terminal!" (To be continued.)
