The pit in front of Wu Di is about 15 meters deep and belongs to a mixed pit of gravel and sand. The proportion of the jadeite rough seems to be quite good, and when you go down the slope of the pit, you can even see the wool directly on the wall of the pit next to it.

"This is supposed to be the first layer, and we have determined that this layer is located 10 meters above the surface and more than half a meter thick after comparing multiple pits and sampling. According to the sampling range, the area is very large, so that there should be thousands of tons of jadeite rough in this layer alone. ”

The engineer introduced as he walked.

"In fact, for this jadeite mine, the price of 200 million is on the low side, because the value of the proven reserves is more than 50 million US dollars. In Guatemala, jadeite has a longer history of formation than in Myanmar, so there should be more ore layers, and some mines have detected even close to ten layers! ”

Wu Di didn't speak, just now he was on the top of the mine, he had already seen through with his perspective eyes, the jade in this pit is not close to ten layers, not even two layers! In other words, except for the half-meter-thick layer of jade ore exposed here, no matter how deep the other places are dug are muck!

He searched the pit for a while, but couldn't find a reason, so he looked straight into the distance.

That's right, there is only one layer in the vicinity of nearly a kilometer, and the thickness is uneven, and the proportion of jadeite rough is relatively low. However, this is obviously a secondary ore formed by alluvium, how can it be only one layer?

Jadeite ore is generally divided into two types: primary ore and secondary ore. Primary ore is due to the strong subduction of the oceanic plate on the continental plate caused by the high pressure, low temperature physical and chemical conditions, so that the mixed deposits are mixed and crystallized to form various minerals or rocks, and then through strong tectonic action (mainly fracture) to make the original rock strongly broken, mixed with Cr, Fe, Mn and other chromogenic elements dyed and mixed with finely ground jadeite rock, and finally re-cemented and crystallized by the finely ground jadeite rock to form various colors of jadeite.

Secondary ores are mainly deposits formed after primary deposits are washed and transported by rivers. So there are generally stratifications. The characteristics of the rough stone are distinct between the layers. For example, the old Hpakant mining area has now been excavated to the fifth layer, and the external characteristics of each layer of jadeite rough are different.

Since this is a river valley, it should also be a typical alluvial secondary mineral, 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, and the location was very reasonable, and from the situation of the pit, he should be able to make a rough assessment of the level of this mining area.

He beckoned to the engineer who accompanied him and walked to another pit more than a kilometer away.

"This is the sampling hole. There are a total of 36 in the mining area, and this mark is a sampling hole for taking out jadeite ore, this one is judged to be a possible mine according to geological conditions, and this one is not. ”

The engineer walked along the way, pointing to some round holes the size of buckets passing by. Wu Di looked at each one carefully, and the more he looked at it, the more he wondered, could it be that this mine was a jadeite mine with only one layer of jadeite deposits?

This is true of the second pit, and the same is true of the third pit, and Wu Di walked through three pits. The entire mining area has been viewed by him, and this is a pseudo-alluvial ore with no development value, only a layer of jadeite deposits in some places.

"Excuse me, have you ever dug for jadeite at a deeper point?"

The Engineer nodded.

"The deepest part of the sampling here reached 60 meters, the shallowest one was 5 meters, and most of the rest were between 10 and 20 meters. The deepest of these was found at around forty meters of jadeite ore, and a dozen more than a dozen remaining sampling sites found rough. But it's between ten and twenty meters. So we judged that this is a rich jadeite deposit, and we need to know the sampling holes......"

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

"Take me to the deepest sampling point."

The engineer led Wu Di for nearly a kilometer. At the edge of the valley, there was a round hole of the thickness of a bucket marked with a mark different from the rest of the place, and the bottom was so black that there was no bottom in sight.

There is only one layer of jadeite here, but this sampling point can actually take out the rough stone from more than forty meters away, is there something wrong with his perspective eye?

He took a closer look and shook his head, the situation here is similar to that of other places, but for some reason, a piece of ore was buried at a depth of forty meters, and one of them may be in the location of the sampling, and it was obtained by the engineer who made the hole and took the sample, I really don't know if it was his luck or misfortune.

This is a jadeite mine, but unlike other alluvial ores, it is a super-thin ore formed only by alluvial deposits.

In other words, in the upper reaches of this river, there may be a place where there is a primary jadeite mine, and after years of river washing, some jadeite has been brought here with the current and deposited. If this process continues for many years, it is very likely that this place will also be covered with jade ore layer by layer, but this one is obviously unlucky, and after not many years of washing, the river dried up or diverted, so such a thin layer was left.

Judging from the current situation, such a large river valley, let alone worth 200 million US dollars, he will not ask for 2 million US dollars to sell him!

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

"Fifth brother, the mines here don't seem to be the same as those in Myanmar, and they don't seem to see any semi-weathered zones and other characteristics......"

The robot cat kept running around with Wu Di, and when he saw Wu Di frowning, he couldn't help but express his opinion.

"Hehe, of course it's different, the secondary minerals we see in Myanmar have been mined for a long time, and we can't see the characteristics. Only in the primary mines in the mountains can we see the mines that have not been mined, but the characteristics of the primary mines are different from the secondary mines, and the secondary ores in the river valleys are generally alluvial secondary ores, which are new minerals formed by the weathering of the primary minerals, so there will be no obvious semi-weathering zone like the primary ore. ”

"Oh, this is a secondary ore formed by alluvium."

"It's a pity, this alluvial is not the other's alluvial!"

Seeing that the robot cat and the sparrow were confused, Wu Di further explained:

"Alluvium, as the name suggests, is a deposit deposited after being washed and weathered by river water, strong winds, etc., and is generally paved in the riverbed layer by layer, and the maximum can reach more than five layers. But for some reason, there is only one floor left, so there is no value in mining. ”

"Oh, so that woman is gambling and gambling is broken. Fifth brother, do you think she knew about this situation and thought about changing hands? ”

The sparrow also understood and made its own judgment.

"It's possible, but it's not quite like it, you see her investment here, obviously she is going to mine it herself, maybe it's really a problem with capital turnover, so she thinks about transferring."

"We all see it clearly, and a fool will buy it! I don't think there's any need to waste time here, let's go and find my own mines. ”

Wu Di shook his head, no one can see whether there are mines in such a short period of time, judging the mineral deposits of a place is based on the comprehensive judgment of various factors, and it is necessary to rely on punching and sampling to draw conclusions. If they make a hasty judgment like this, they are afraid that they will offend that woman to death. Think about it, if you don't have a clairway eye, you can look at it so casually for an hour, and you will veto the efforts that others have spent two or three years, or even more than ten years, and you won't be considered a trick!

Wu Di found the engineer just now and asked:

"Is the machine you are sampling here still operating?"

"No problem, we have arranged for a few workers to be here, but we can only make three holes for you to sample for free."

"Oh?"

"If we had done a lot of sampling holes, the price might not be $200 million, but $300 million, $400 million, or even more."

Wu Di smiled and said:

"It could be fifty million, twenty million, or even worthless, isn't it?"

"That's right, that's right, that's the charm of gambling mines, hahahaha."

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

"I don't ask you to choose a new place to take samples, just give me a deeper spot in the sampling hole where you found the jadeite, and take samples at 20 meters, 30 meters, and 40 meters respectively?"

"No problem, but after all, this is sampling, the area is too small, even if nothing is taken, it does not prove that there is no mine here, after all, one-third of the sampling holes here have taken out jadeite, and those pits have dug up jadeite, which is the most convincing."

Wu Di nodded, what he said is very reasonable, if there is no mine according to the sampling holes, then there is no such thing as gambling mines, I heard that there are hundreds of sampling holes in the rich mine, and a piece of rough stone that can prove the existence of the mine has not been taken!

The next thing is a boring wait, Wu Di has already used the Book of Heaven to probe just now, although he has not been able to accurately estimate the extent of the scope covered by the Book of Heaven, but at least three or four kilometers is no problem, that is to say, there is nothing to do within five kilometers around this mine.

Seeing that Wu Di still wanted to take samples for such an obvious bonanza, Ivanova couldn't help but stab him twice, and directly summoned the helicopter back to the city to rest. Anyway, you've all brought your luggage, so stay in the mine for two days, and I'll pick you up when the time comes.

Seeing the helicopter take off, the sparrow raised his eyebrows,

"Fifth brother, I asked, it will take at least more than 20 minutes to hit one meter down, there are few of them, come one by one, these three sampling holes will take at least two days, it is better to ......"

"Hehe, then you have to leave someone here to watch? Otherwise, wouldn't they be able to fool us casually? Besides, if you want to buy a mine, and you don't stare at it from the side, isn't there a problem when you look at it? ”

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

"Come on, Divergent Terminal!" (To be continued.) )
