Several experts gathered around the drawings, bowing their heads and carefully analyzing.

"It's a pity, these two boreholes are less than ten kilometers below the Lost Dragon Valley, a little off." Some experts sighed.

Zhu Yanxi continued to introduce the old information: "In the past, the geological team also took a lot of rock samples in the Milong Valley and sent them for analysis, but it was found that the surface gold content of the Milong Valley was not high, so there was no in-depth exploration work. ”

One error in judgment and one missed a whole gold deposit!

Many people can't help but feel sorry for the geological team.

So the question is, how did the mining company in the book find that there are gold deposits beneath the Lost Dragon Valley?

Everyone's eyes turned to Xu Xin, whose face was slightly green.

He Xi smiled warmly and asked Xu Xin beside him, "Why did you choose to set up a gold exploration project here in the first place, and is there any basis for judgment?" ”

In the face of many pairs of curious eyes, everyone around is an experienced expert in their field.

Xu Xin couldn't help but get nervous.

There are some things that really can't be explained.

But there are some things, even if they can't be explained clearly, they have to be explained head-on.

After polishing his thoughts a little, he slowly spoke: "Speaking of this, I have to thank my senior, Senior Yan Peng!" ”

As he spoke, he bent down ninety degrees and bowed to Yan Peng, with a very respectful attitude.

Yan Peng took this bow, stretched out his hand and patted Xu Xin's shoulder, "I just showed you the old information from the past, you can find placer gold deposits, it is your own efforts that account for the vast majority." ”

On the way here just now, He Xi took a car with Yan Peng, just to discuss the content of hydrology.

Regarding the diversion of the Huangjiang River, He Xi already knew about Yan Peng's mouth.

He still has a lot of questions to figure out, "According to Yan Peng's previous research, the runoff before the diversion of the Lao Huang River was more than 1,000 kilometers long, why did you choose to set up a project in Milong Valley?" ”

It is possible to grasp one of the points from the vast expanse of land at a glance, and there are abundant minerals underground.

This is not a geology expert, but a feng shui master!

Looking around, there is a sense of scrutiny in both eyes.

Xu Xin was under a lot of pressure, and carefully considered his words, "When I first came to Lost Dragon Valley, I came with Chief Engineer Song. ”

Song Yizong was originally standing at the back of the crowd, and when he heard Xu Xin mention his name, he hurriedly raised his hand, "Yes, I came to this cliff with Xu Xin, and I stood in my current position at that time, and made an analysis of the topography of the Lost Dragon Valley. ”

Following Song Yizong's words, Xu Xin nodded thoughtfully, "What Chief Engineer Song said at that time gave me a lot of inspiration. ”

He walked closer to the edge of the cliff and pointed to the open valley and the mountains to the north, "Chief Engineer Song said that the ancients summed up a lot of experience worth learning from in gold exploration.

Among them, there is the content in the "Pipe and the Ground", and if I remember correctly, it is called "Those who have dansha on it, and there is gold under it".

I have checked on the Internet, the so-called dansha is actually a mineralization of mercury sulfide, red in color, which has a very obvious indicative effect on the search for gold deposits. ”

"You're right, mercury and gold have proven a high probability of co-occurrence in many mines, and finding gold through mercury is really one way to do it." Some experts agreed.

"With this analysis, you can see that you have put a lot of thought into it." He Xi also nodded in appreciation.

Some experts also questioned, "As far as my eyes can see, I haven't seen any distinct mercury sulfide ore in Milong Valley, where did you see it?" ”

Another conundrum.

Xu Xin felt like he was about to go bald.

Dealing with these experienced experts, saying a little wrong word, immediately showing the original form, and accidentally ending up by yourself.

His mind was spinning rapidly, and he remembered his perfunctory father's words before, and said slowly: "The analysis of rock samples on the old data has done an analysis of the content of mercury elements, and this area is generally high, including here in Milong Valley.

However, red mercury can be seen everywhere else, but not here, which makes me suspicious. ”

The reasons are far-fetched, but there is nothing to find fault with.

Previous data on the chemical analysis of rock samples covered a large area, and the mercury content was not limited to here.

This is not enough to support the argument for in-depth exploration here.

"Hmm." He Xi nodded, "Go on." ”

Xu Xin felt that he was really running out of words, there was no way, let's fool.

"Chief Engineer Song also said that many predecessors summed up the sayings of 'three mountains' and 'four non-exposed' in order to find gold mines."

This is a folk saying, an empirical one.

Geologists here, who have worked on gold projects, have probably heard some of this argument, but in the rigorous geological industry, they generally do not follow this kind of experience to guide their work.

As an adjunct, it is feasible.

Song Yizong stood in the back row, full of question marks, why did he mention me again?

"Do you see something different about this valley?" He Xi smiled, looking into the distance with a pair of cloudy eyes.

Xu Xin stood on a raised stone on the edge of the cliff and pointed into the distance, "Let's look at the overall framework of this valley, does it look like a net bag?" ”

No expert agreed with this statement, and they all looked at the valley in silence.

has been nonsense to this point, Xu Xin is already riding a tiger, and continues to talk nonsense: "The lower is wide and the upper is narrow, the river flows here, the flow rate is slow, the gold sand is precipitated, and it has been like this for many years, and it has naturally formed placer gold deposits.

Also, you can see that the exit of the Lost Dragon Valley has narrowed from a wide area in an instant, forming a small opening, a natural rock barrier, like a threshold, preventing the golden sand from continuing to flow downstream. ”

Sounds like that.

An expert held his chin and muttered: "Don't say it, the entire Lost Dragon Valley is indeed a bit like a fishing basket, there are in and out. ”

Other experts were silent.

He Xi shook his head, "This statement can't be the basis for drilling. No geological metallogenic conditions have been found on the surface, and I don't think it's advisable to judge by the topography alone. ”

As soon as he heard this, Xu Xin hurriedly accepted his posture of pointing at the country.

What needs to be said has already been said, and as for whether the experts believe it or not, or how to deal with it, it is not up to them to decide.

He Xi turned his head and asked Xu Hengqiang: "As the chief technical engineer of the surveyor, on what basis do you arrange the drilling rig?" ”

Xu Hengqiang's black face didn't see too many subtle expressions.

Since paying off the bank loan, no matter what he faces, he can be relaxed and indifferent, and he is not so forward-looking.

Moreover, the results of the Milong Valley gold exploration project proved to be excellent, which can mask any irrational processes.

"This is the old riverbed, and topographically, there are indeed conditions for gold placer deposits. At the beginning, drilling a hole was purely to test it, and if there was no mine, forget it.

As a result, the mine situation was so-so, and it was passable, so it was directly rolled out and drilled. ”

Although his statement does not conform to the standard steps, it is not uncommon in the geological prospecting industry.

Many times, prospecting work is at a dead end, and it is a good idea to drill down to see what is going on underground.

It is also the most direct and effective method.
