After hanging up the phone, Xu Xin saw that there was a missed call reminder on his phone, probably from the time he was on the phone with Bai Yifei just now.

He clicked on the missed call and dialed it.

"Xu Xin, Lao Xu asked me to inform you that the drill hole drilled the day before yesterday in Milong Valley has already been mineed." Jiang Yehu's voice.

For this result, Xu Xin was not surprised or surprised at all.

On the other end of the phone, it seemed that he was waiting for Xu Xin's emotional outburst, but unfortunately Xu Xin's reaction disappointed him.

"Have you laid out the drill?" His voice was flat.

"Uh...... Doesn't your voice sound very happy, this is your mining right, aren't you happy to see the mine? ”

"I'm so happy, should I laugh a few times to be more appropriate, or chant a poem?"

Xu Xin said, and really pretended to laugh a few times.

Sounds perfunctory.

"You're really calm, so calm!"

Jiang Yehu admired Xu Xin's mentality, "Lao Xu will be here in a while, do you want to come over?" ”

"To come, such an important moment, I must witness!"

After hanging up Jiang Yehu's phone, Xu Xin suddenly became difficult.

I made an appointment with Zhao Tianni yesterday, and today I went to the playground, bungee jumping and roller coaster, etc., which can scare heart disease, and they all have to try it today.

For this kind of amusement, Xu Xin has always been very spittening.

There was no way, I promised Zhao Tianni to watch "No Acting" before, but I broke my promise and wanted to accept punishment.

From childhood to adulthood, Xu Xin's hobbies were often quiet things, such as sleeping, playing games, and being in a daze.

The courage is still very small, and when I see a kitten and a dog, I have to take a detour.

Zhao Tianni's temperament is just the opposite, she pursues excitement, knowing that Xu Xin is afraid of dogs, and instigating her parents to raise two fierce mastiffs.

Until now, Xu Xin still firmly believes that Zhao Tianni raised mastiffs purely to scare him out of heart disease and murder him.

Today is even more excessive, she wants to go bungee jumping, and she also said that she will push Xu Xin off the cliff with her own hands!

This tiger girl, when she was a child, she always had two snots under her nose, and the sound of eating noodles was like a pig eating, and she kept long nails just for the convenience of picking her teeth and buttoning her nose......

It's full of shortcomings!

Such a girl, why do so many people criticize her for writing love letters?

On second thought, there is something serious today, and you don't have to be pushed off the cliff!

He hurriedly dialed Zhao Tianni's phone.

"Xu Xin!"

The shrill sound is like a pair of scissors stuck in the eardrum.

"Be quiet."

"I'm waiting for you at home, come and pick me up!"

From this excited voice, she could hear that she couldn't wait to push Xu Xin off the cliff.

"I have something to do today, and I can't go play."

"You coward, aren't you a man?"

"I'm not a man, I'm just a coward. I really have a job today, I'm going to go to the mine soon, if you don't believe me, you can come with me. ”

"Really?"

"Of course it's true, lie to you I'm a dog."

"Then you come and pick me up, I want to climb the mountain with you, too."

"I ......"

When Xu Xin heard the word "climbing the mountain", he suddenly regretted it.

Bungee jumping is good to have a rope to pull, it may scare out a heart attack, but you can't die.

After climbing the cliff, you will be crushed when you go down.

Picking up Zhao Tianni in the car, Xu Xin drove the car and went straight to Milong Valley.

When I arrived at the village, there was a mountain road of about three kilometers to the Milong Valley, which could not be reached by car.

Zhao Tianni is from the city, and she is like a wild horse on the mountain, jumping and jumping, so unhappy, and surprised at everything.

In order to catch a butterfly, she jumped into the nettle grass, and the bare skin of her hands and feet instantly turned red, as if countless caterpillars were crawling past.

This pain will be remembered by her for the rest of her life.

Xu Xin was very happy and couldn't wait to laugh out of the pig cry.

But he had a strong survival instinct, and he kept frowning, as if he felt empathy, and blew on her stinging spots.

When I arrived at the entrance of Milong Valley, I came to the bottom of the tarpaulin of the drilling rig, and sure enough, I saw Xu Hengqiang, Jiang Yehu and others were there.

"Here we are."

Xu Hengqiang beckoned to them.

He was also very surprised when he saw Zhao Tianni coming, and then saw that her hands and feet were red like boiled crab claws, and he frowned and asked, "What's the matter?" ”

"Dad Xu, my hands and feet hurt so much!" Zhao Tianni called.

Xu Hengqiang glared at Xu Xin, "What's the matter, you let Tianni suffer so much, I'll clean you up when I go back!" ”

He could tell at a glance that it must have been stained with nettle grass.

"She jumped in by herself, I can't pull it, you can't blame me!" Xu Xin is speechless.

Zhao Tianni glared at Xu Xin, regretting that she didn't bring the mastiff over.

"It's okay, it's okay, it'll be fine in a while."

Xu Hengqiang handed Xu Xin a bottle of water and winked.

Xu Xin took the water and poured it on Zhao Tianni's hands and feet, and the cold water could slightly relieve the stinging sensation.

Da Da Da ......

Next to the drilling rig, core boxes are lined up, and in each core box, cylindrical cores are neatly stacked.

Jiang Yehu is hammering the core with geological technicians and drilling rig workers.

After seeing the mine today, I quickly hit the bedrock of the bottom plate of the ore layer.

As a placer gold deposit, if you see a normal rock formation, you can basically conclude that it is the bottom plate of the ore layer.

After receiving Xu Hengqiang's instructions, Jiang Yehu asked the drilling rig to drill an additional 50 meters before notifying the final hole, and came over to take core samples for chemical analysis.

Because the mountain road was difficult to walk, they didn't bring in the sampler, so they had to tap the core by hand.

Select the ore layer, as well as the upper and lower layers of the ore layer, split the core in half, and take half of it as a sample.

After measuring the seam using a trace element analyzer, the ore was well intersected with a gold content of 3 g/t to 6 g/t gold in the seam.

The recoverable thickness of the ore layer has reached 2 meters!

Even if it is based on the standard of rock gold, it has already reached the standard of industrial mining.

From the point of view of the geological exploration specifications for placer gold, this is an excellent ore situation!

On the core of nearly 150 meters in the upper layer of the ore layer, it is all a semi-condensed layer of sediment, as long as it is struck with a hammer, the core is easily broken into sand, which is mainly composed of quartz, siliceous rock and so on.

The floor of the ore layer is limestone, in which there is breccia, and there is no occurrence.

From these geological phenomena, many conclusions can be drawn.

For one, it's really an old riverbed.

Second, below the riverbed, it's really a structure.

The hard evidence fully proves all the previous speculations.

This is the old Huangjiang River.

Before Xu Hengqiang came to Milong Valley just now, he had communicated with Jiang Yehu, is there a possibility that the bedrock at the bottom of the riverbed is the primary ore occurrence stratum of the Huangjiang Gold Mine?

But the breccia-bearing limestone at the bottom was measured with a microanalyzer, and the gold content was not high, or even almost none.

It seems that the bottom of the riverbed is not a primary deposit, and the real primary ore is still in the upper reaches of the Laohuang River.

The gold placer here is brought by the river and deposited.

There was no point in continuing to drill, so it was decided to end the hole.
