At the door of the hotel, Xu Xin waved his hand at everyone and got into the car.

Today's work is over, and he is going back to his home in Xingfu City, after all, the journey is not too far.

As for He Xi, Song Lejia and others, they don't need him to worry about it, they have He Penghui's own arrangement.

As soon as I started the car, the passenger door suddenly opened, and in the dim light, I could vaguely tell that it was a girl.

"Zhong Manman?" Xu Xinle was happy, "Do you have bad eyes and always get in the wrong car?" ”

"Hmmm......"

Zhong Manman's mouth suddenly rang like a mobile phone that was adjusted to vibrate, and after a long time, he squirmed and said, "Editor Shu scolded me just now." ”

"She is the leader, and she scolds you for valuing you." Xu Xin smiled.

"She asked me to follow you all the time, not to leave an inch, to sleep, to go to the toilet."

"Are you serious?"

"If I can't complete the task, I won't be able to find a job if I don't pass the internship assessment!"

After Zhong Manman finished speaking, he lowered his head, as if he was sad or sulking.

Just when Xu Xin thought she was going to cry aggrievedly, she suddenly raised her head and clenched her fists to cheer herself up, "I can do it, come on!" ”

Then, she fastened her seatbelt, turned her head sideways, and said in a normal tone, "You drive." ”

It's a silly girl.

Xu Xin's shoulders shook with laughter, "Are you sure that one person will follow me without a cameraman?" ”

"I'll just take a picture of you with my phone."

Zhong Manman said, took out his mobile phone, turned on the camera function, and shot at Xu Xin, "It's so dark, I can't see clearly, forget it." ”

"Are you sure to come back to Happiness City with me?"

"Uh-huh!"

"You're not afraid of danger?"

"You're not a bad person, I can see people accurately, and I can see the thieves and villains on the street at a glance."

……

Xu Xin took Zhong Manman back to Happiness City.

Zhong Manman didn't really stick to Xu Xin, but had already booked a hotel, and after Xu Xin sent her to the location, he returned home.

According to his own plan, Xu Xin drove to the mining office building in Shushu early in the morning.

Well, the horn honked, and while waiting for the electronic door to open, the window sounded a banging sound.

Zhong Manman stood by the car door, smiling all over his face, his mouth moving, because the door was well insulated, and he couldn't hear what she was saying at all.

I saw her holding a selfie stick in her left hand and two plastic bags in her right hand, which contained soy milk and meat buns, which could be seen to be double servings.

Xu Xin knew that Zhong Manman was turning on the mobile phone recording function, and waved his hand out of the window, just as the electronic door was fully opened, he tapped the accelerator and came directly to the door of the office building.

Outside the gate, Zhong Manman stomped his feet, carrying two bags of breakfast, and was about to catch up with the back of the car.

Wangwang......

Uncle Ge led the wolf dog and blocked in front of Zhong Manman.

An old man and a young man stared at each other with big eyes, and the tip of the needle was on the wheat mang, and they looked familiar.

"I know your boss!" Zhong Manman stared at a pair of big black eyes.

"Liar, our little boss didn't pay attention to you." The scene just now, Uncle Ge saw it in his eyes.

"Humph!" Zhong Manman wanted to flip through the electronic door with his bare hands, but looking at the big wolf dog with bared teeth and grinning, he finally dispelled the idea.

……

Xu Xin came to the second floor to take a look at Bai Yifei's office, and found that no one was there, so he asked the office and learned that Bai Yifei had been supervising the work in the area of Milong Valley recently.

He found a computer, sat down and got to work.

Within the stratigraphic analysis horizon, seven recently automatically drawn profiles are suspended on the front page.

There are three sections of the Kimberlite mass.

Each kimberlite rock mass is marked with dots of red dots, and each red dot represents that the diamond content in the corresponding area has reached the boundary taste, and even reached the industrial grade.

However, these scattered red dots cannot be connected into a piece to form a mineral belt.

However, on the first section, there is a certain pattern of diamond particles, the top of the kimberlite rock mass diamond particles are relatively sparse, the deeper you go, the larger the diameter of the kimberlite tube, the higher the density of diamond particles.

Even at a depth of 500 meters, the red dots representing the diamond ore are densely packed, and even the red patches can be seen when the map is reduced.

Xu Xin's job is to draw three cross-sectional drawings of the Kimberlite rock mass on the computer, and mark the diamond content of each red dot.

The last step is to make a table and count the ore situation.

It's not hard to draw a profile, it's hard to look at the diamond content data for each red dot, as well as summarize the work.

It wasn't until it was dark and someone came over to call for dinner, Xu Xin saved his work, and after eating in the canteen on the first floor, he chose to go home.

As soon as he got out of the gate, he opened the car window and waved his hand to the security booth to express his gratitude to Uncle Ge.

In addition to seeing Uncle Ge with a kind smile on his face, he also saw Zhong Manman sitting on the steps next to the security booth, carrying a plastic bag, gnawing on cold meat buns in his mouth, and his mouth was stuffed to the brim.

It looks like she's eating buns that she hasn't finished in the morning.

"Uh-huh-hmm......"

Seeing Xu Xin driving out, Zhong Manman hurriedly stood up and shouted something indistinctly.

But looking at the butt of the car that was gone, and looking at the red tail lights that disappeared into the traffic, she grabbed half of the bun left in her hand, and after chasing for more than a hundred meters, she could only give up helplessly.

Two days later, Xu Xin also came to the office early and left very late.

In the security booth next to the gate, Zhong Manman can be seen squatting on the steps every day, looking like he has become good friends with the big wolf dog.

At work, the results were also obtained.

He set up several diamond ash content ranges by himself, and made a statistical table for each profile and a summary of the statistics.

Among them, there are 6 points where the diamond content is greater than 400 mg/cubic meter;

There are 26 points with content between 100 mg/m3 and 400 mg/m3;

Below 100 mg/m3, 279 were reached.

The content was greater than 100 mg/m3 at 32 points, all concentrated in the deepest part of the first profile, almost close to 500 meters.

Xu Xin didn't know how the system measured the local ore content, nor did he know what the 32 points with high diamond content meant.

Is there a single gem-quality diamond in one cubic meter of rock, or are there multiple diamonds?

Or is it the average amount of diamonds in a certain numerical volume of rock?

With the data currently available, it is not possible to determine how many gem-quality diamonds exist in the ground, nor can it determine the true economic value.

As with many mineral prospects, drilling is necessary to determine whether the reserves can be calculated or not.

But unlike conventional exploration work, Xu Xin at least knew that there was indeed kimberlite under the first prospecting target, and that kimberlite contained diamonds, and it was very likely that there were gem-quality diamonds!

From the profile, it can be found that the kimberlite tube in the first prospecting target area is higher the deeper you go, the higher the diamond content.

Looking at it this way, one can't help but wonder if the diamond grade is higher at a depth of more than 500 meters in the kimberlite pipe.

Are there high-quality extra-large gem-quality diamond grains in excess of ten carats?

In addition to the diamond content, the situation of the kimberlite mass is also clear at a glance.

The kimberlite rock tube in the first prospecting target area is narrow at the top and wide at the bottom, and the deeper it goes, the larger the diameter of the rock mass, and the diameter of the rock mass reaches almost 300 meters at a depth of 500 meters.

The other two kimberlite tubes in the prospecting target area are relatively small, with diameters ranging from tens of meters to tens of meters, and the ore occurrence situation is not optimistic

After repeatedly studying the information currently in his possession, Xu Xinzhong already has sufficient basis for making decisions.

glanced at his mobile phone, and when he was still at work, he directly dialed He Xi's phone.

"Xiao Xu!" He Xi's voice carried a hint of warmth in the vicissitudes of life.

"He Lao, I have some thoughts of my own here, and I want to discuss them with you."

"You say."

"I decided to invest in a diamond prospecting project."

"Really?" He Xi's laughter came from the voice, as if he had expected Xu Xin's decision.

"I thought about it for three days, whether from an economic point of view or from a humanistic point of view, I think this is a project worth investing in."

"I hope your input will pay off, but prospecting is full of uncertainties, and you really made a deliberate decision?"

"Of course, I'm very conscious now." Xu Xin couldn't explain the fact that he was able to see through the underground.

"Our current level of work can only confirm that the first prospecting target is a hidden kimberlite rock mass, and the other six prospecting targets have not yet been determined. The next step is to determine the presence of kimberlite in the other six prospecting targets. ”

"Okay." Xu Xin did not directly say where there is a kimberlite rock mass, and the explanation is not clear, "He Lao, I have to explain to you again, the mining industry in our book is currently unable to come up with a large amount of exploration fees, and we have to wait for a period of time for the Milong Valley mine to see the benefits before the project can be launched." ”

"It's okay, we can get the prospecting right down first, and it's valid for two years, so there's no hurry."

"Okay, listen to your arrangement."

"I directly informed 107 that the materials for applying for prospecting rights have begun."

"He Lao ......"

"Huh? If you have something to say, please speak. ”

"You said before that you would invest 2 million in this diamond prospecting project without asking for a return, but after we studied it here, we thought it was not appropriate."

"Any concerns?"

"I think so, since we are the mining rights in the book, this is a business investment, and we have to pay attention to business principles. No matter how much exploration fee is required to determine the final exploration implementation design plan, the mining industry in our book will pay this cost in full. ”

"Are you sure you don't want these two million?"

"Sure, no."

"You young man's mind, I can't understand this old man." He Xi said with a smile.

Xu Xin's idea is very simple, no matter what the final result of the diamond project is, it must not leave hidden dangers or various disputes because of the free donation of two million.

Confidently, it's not bad for this money.

After hanging up the phone, he fell into a dilemma again, and had a headache for a larger sum of money.
