At this time, the huge camera was already aimed at everyone, recording their conversation into an image.

Xu Xin's attention had to be attracted by these news devices again.

He Xi saw Xu Xin's gaze and hurriedly asked, "They are the staff of the Black Gold Satellite TV News Center, do you mind if they record this matter?" ”

The camera focused on Xu Xin and gave him a long close-up.

Among these people here, He Xi has the highest rank and Song Lejia has the highest rank, but the two of them just gathered next to Xu Xin.

He Penghui, Shi Lei and others even stood half a position back.

Others formed a circle around them.

Unconsciously, Xu Xin stood in the center.

The videographer easily found the focus of the shot.

Xu Xin didn't like the camera to be aimed at him, looking at the flashing red light on the camera, he had a sense of oppression aimed at by a sniper rifle.

"How can there be media workers here?"

"They are interested in the historical project of finding diamonds in our province, and they plan to make a long documentary and follow us throughout the whole process."

Song Lejia said, pointing to a middle-aged woman with a fortune next to the camera, "Her name is Shu Linfang, she is the deputy editor-in-chief of Black Gold Satellite TV, and she is in charge of all the columns of the news center." ”

The middle-aged woman named Shu Linfang smiled at Xu Xin, "I've heard your name for a long time, and I've been looking for an opportunity to give you an exclusive interview." ”

She pointed to the young female reporter holding a microphone on the other side of the camera, "Her name is Zhong Manman, and she will follow you to do the filming work in the future, please take care of it." ”

The young female reporter named Zhong Manman has a round face, a pair of round eyes, and a pair of small hands holding the microphone constantly rubbing back and forth, looking nervous.

Xu Xin glanced at He Xi and Song Lejia, and didn't know how these news media could appear here.

He has always wanted to do his own thing quietly, and he didn't want to be exposed to the public eye and accept everyone's judgment.

He doesn't have a crush on cameras.

It's best if these people are just on a whim and come over today and take a casual picture.

Later, I found out that the prospecting work was boring, and there were no events, conflicts, contradictions, etc. worth attracting the attention of most people, and then left.

"He Lao, why don't we go over and see the scene directly?" Xu Xin didn't want to pay attention to these media people.

"Okay."

Just after a cigarette was smoked, He Xi did not specifically greet these newsmakers.

Starting from Donkey Ping Village, they followed a valley and kept moving forward.

The local villagers were very enthusiastic and even walked like a fly in front of them to show them the way.

Everyone here knows where the diamond primary mine is located.

They came to a gentle slope that stretched for two or three hundred meters, with a height difference of only more than ten meters.

At a glance, all I could see was a patch of weeds, and loose dirt at the bottom of the weeds.

"This is the first diamond primary ore discovered in our Huaxia Kingdom!"

He Xi pointed to this gentle slope that he had encountered countless times, his eyes were full of melancholy, like seeing a lover whose face was not there.

With his fingers, everyone's eyes looked at the hillside with a small slope.

The camera also moved up.

Most people don't see anything at all.

The famous Donkey Ping No. 1 diamond is such an inconspicuous hillside?

Before Xu Xin came, he had done some work, but he was still confused when he looked at the overgrown hillside.

If it weren't for the clear coordinates, let him come and look for ore alone, I'm afraid he wouldn't be able to find this place.

"In the past, a lot of trenches were dug in the mountains, and some trenches ran from the bottom of the slope to the top of the slope."

While walking up the hillside, He Xi introduced, and pointed to a slightly concave soil pit at his feet and said, "There is a trench here." ”

After decades of exposure to wind and sun, these trenches have gradually been buried, with only shallow traces.

Walking up along the trench, I finally saw a relatively well-preserved trench at the top of the slope.

He Xi was in his seventies, but he still climbed into the deep pit, dug a small pit at the bottom with a geological hammer, and reached out to grab a handful of fresh soil.

Xu Xin also jumped down.

"Look at this thing, can you recognize it?"

He Xi held a handful of loose soil in his hand, gray-green with earthy yellow, and the texture was soft.

Xu Xin picked up a little dirt from his palm, looked at it carefully, and said in confusion: "Isn't it ordinary fourth-series soil?" ”

"This is no ordinary dirt."

He Xi smiled and shook his head, "This is what kimberlite looks like after serious weathering, at the beginning, everyone characterized this rock as potassium magnesium porphyry, and in recent years, everyone has redefined it as mica kimberlite, which is different from the kimberlite found in large diamond mines abroad." ”

As he spoke, he stacked his palms covered with age spots and rubbed the weathered kimberlite in his palms vigorously.

The palm of the hand is open, and after a few strokes in the middle of the loose dirt, a small particle of a certain hardness is picked up from the middle.

The small grains resemble a green bean, with a dull green color.

He twisted the "mung bean" and said with a smile: "This is chrome pyrope garnet, which was originally supposed to be purple-red, a very easy to identify color, but because of alteration, it has become what it is now." ”

Xu Xin stretched out his hand to catch the "mung bean" and looked at it carefully.

"Spessartine garnet is a marker for finding kimberlite, and it's often set right in the middle of kimberlite."

"What do you mean, that's what we're going to do next is to look for diamonds through this mark?"

Xu Xin knew that if he found kimberlite, he would hope to find diamond.

He Xi shook his head, "This method has been used for decades, and the corresponding kimberlite has been found in places where chrome-magnesia garnet can be seen on the surface, but many kimberlite bodies have not been found to contain diamond. ”

The content of their conversations, which contains a lot of technical vocabulary.

Rao did some preparations, but Xu Xin still had a hard time listening to it, trying to digest He Xi's words.

At the end of the day, he still doesn't have enough knowledge.

They crawled out of the trench.

He Xi patted off the soil on his hands while looking at the surrounding grass and trees, "Taking you here to see, on the one hand, is to let you see the heritage of our black gold province for more than 70 years of diamond prospecting, or the historical accumulation."

On the other hand, I would like to explain to you that this land, the so-called diamond prospecting hope. ”

Following his fingers and gaze, everyone present only saw the vast mountains.

On the mountain, there is a blue sky and white clouds.

Beneath the mountain are invisible layers of rocks.

Where is the hope?

"Prospecting hope, prospecting potential, these words, I have seen countless times in many diamond mineral materials in Heijin Province."

Xu Xin has read a lot of papers in this area, but he has not systematically learned this knowledge, and he has not formed a clear knowledge structure in his mind.

"To be honest, I have seen a lot of analysis of metallogenic theory on the Internet, but after I read it, I really don't understand it thoroughly. ”

Not only Xu Xin, except for Song Lejia and He Penghui, two old geologists, everyone else may not know much about this knowledge.
