The Treasure Hunt of an Antique Dealer

Two special stainless steel boxes were opened one after another. The larger one is closed and wrapped with a soft gasket material and soft leather, just like a closed plaster mold, so that it will not damage the precious natural gold nugget inside. .

Seeing it clearly, Zhang Nan said: "I'm interested, Mr. Glasswar."

Sir, let the gold mine manager feel a little flattered, and hurriedly said: "I just ran into it, good luck, boss, no trouble, no trouble!"

Kotou gold is not a meteor. It is generally formed under gold-rich groundwater and bio-enrichment near gold mines. It is formed by enrichment and sedimentation under suitable conditions nowadays, and it can only be found in gold mines.

Its purity is not particularly high, and generally contains a lot of stones and various impurities, most of which look pitted.

Because the environment produced by Kotou gold is mostly surrounded by sand grains rich in groundwater, the potholes on the surface are inlaid with sand and stones.

The sand stone fell off in the later stage of the formation of the gold nugget, leaving pits in the shape of sand stone on the surface. And some of the so-called nugget gold, or even gold attached to a large stone, at first glance is more appropriate than a piece of ultra-highly enriched gold ore.

Kotou gold is produced almost all over the world. Basically, the existence of gold mines means that there may be a difference in size and frequency of Kotou gold.

There is a mining company in Zhang Nan's collection. There are a lot of dog head gold in Zhang Nan's collection. Some of them are displayed in the manor, and some are in the gold mines of the Star Mining Group's continents, the exhibition rooms of the headquarters of the gold mining companies, or the vaults.

No matter where it is placed, it is a good thing for him anyway.

To ordinary people, this kotold gold seems to be very rare. In fact, the absolute amount is quite large, and the smaller ones are uncountable. Some organizations have done statistics and calculations when they are idle. There is 8000~10000 yuan!

Australia has the largest number of kombu gold, which accounts for 80% of the total. The largest piece weighs 235.87 kg, ranking first in the world!

I have many gold mines in Australia, and I always find some big and small kowloon gold every year, but because of large-scale industrial mining, when many are discovered, this appearance has become less than Zhang Nan's viewing requirements.

Many of them either flowed into the kowloon gold collection market, or simply melted and refined into ordinary commodity gold. Only a handful of them are privately collected by Zhang Nan, a crazy collector.

There are quite a few of them, and there are countless other treasures, but I can still thank you for saying "you have a heart", because the two nuggets in front of you are really beautiful!

The big one is a triangle, similar to a triangular plate with a 60-degree angle, placed upright, this is a golden mountain!

The old saying goes that there are seven greens, eight yellows, nine reds, and the big gold nugget in front of you is golden in color, and the purity is definitely above 80%, even 90%.

Purity is secondary, and more important is the shape and its own characteristics-this is a natural spongy gold nugget!

Precious, rare, supernatural craftsmanship of nature!

Sponge is more complicated than burnt coke and the most complicated coral structure. There are very few natural gold nuggets in this form. Even if there are, many of them are either wrapped with large stones that cannot be taken out, or gold is attached with a sponge structure. On the cornerstone.

Beautiful, this Jinshan is really indescribably beautiful!

Zhang Nan got up and approached Gootoujin and took a closer look. In the hole that is n orders of magnitude more complex than the spider web, there is actually no small pebbles or sand in the hole.

It has been an old habit for many years, even if the light conditions in the living room are excellent, Zhang Nan still asked the waiter for a flashlight, and opened it to look at the details.

Nowadays, there is less time to plug the flashlight into his pocket, but naturally someone will help him with it when he goes out.

Under the light of the flashlight, you can see the inner structure of Jinshan, and finally you can see that there are very few small sand particles stuck in it-this is clean enough and difficult enough!

This is Jinshan artificially impossible to make, only magical nature can do it. And it has not experienced any erosion by natural water, whether it has not been within hundreds of years or hundreds of millions of years, otherwise these complex spongy structures will collapse.

As soon as it collapses, it becomes a golden sand, a small golden nugget, a small golden nugget, rather than a whole golden mountain!

Zhang Nan, who put down the flashlight, did not go to get the second piece of gold, but said to Monte Bolivar: "This gold mountain was dug from our own mine?"

"Yes, boss." Monte hurriedly said, "It's in the northern mining area, very close, less than 30 kilometers from the State Guest Hotel. In the col, there are both surface mines and underground mines. It was found more than one meter above the surface.

The quality of the gold mines in that mining area is very good, with an average taste of almost 70 grams per ton, and even more than 500 grams per ton in some areas! "

"So rich? This is rare!" Zhang Nan said, "I remember that in general industrial mining, there are two or three grams per ton that has mining value. Of course, it must be in a place with convenient transportation. This is obviously not feasible.

In South Africa, there are generally more than ten to twenty grams per ton. The company looked for diamonds in Canada, but it has drilled an average of nearly 150 grams, and some of them are a special case of a ton of 9 kilograms of gold.

The average here is 70 grams, which is pretty good.

Since it is not far away, I will go to the mine to see the day after tomorrow.

By the way, does the mine implement an hourly wage system or an output system? "

Different recording systems have something to do with this "Golden Mountain." Zhang Nan asked casually.

Hearing what the boss said about this, Monte Bolivar showed a slightly embarrassed expression. Hearing to ask him a question, he quickly answered: "It is a production system, and all local miners are used. Only the weight of the ore that is dug out, the more you do, the higher the salary here.

There were three miners who discovered this piece of natural gold. According to the mining regulations, there is no need to give other rewards, but we still gave some money as a bonus.

It's too special to justify not giving extra rewards.

But boss, the road conditions of the mine are OK, ordinary off-road vehicles can pass through, but it is considered to be a relatively high altitude in the dozens of company mines under my control, and the air above is not so good. "

"How high is that?"

"About 4800 meters." Monte Bolivar said.

"4800?" Zhang Nan was taken aback, glanced at Christopher Bell, and then said to the mine manager: "I remember Kerry told me that almost all mountain gold mines here are semi-manual and semi-mechanized operations.

Do you guys do the same above 4800 meters? "

The boss actually wants to go to the top to see, the slightest embarrassment of Monte-Bolivia just now comes from this altitude. Upon hearing the question, he replied: "Yes, boss.

Many of our mines here have high altitudes, around 4000 is considered a good place, 4800 is not the highest, so no matter what kind of mine, the taste must be high to have mining value, otherwise it is not economical.

The miners are harder, and the aboriginal miners here can adapt, but like me, it’s okay to go up without work, and you will not be able to breathe after working hard. "

Zhang Nan smiled bitterly after hearing it~www.readwn.com~ and asked: "How much oxygen is in the upper part?"

"I can't tell you the specifics. It may be half of the eastern jungle. No one has ever measured it, boss."

Half of the jungle, Monte obviously meant the concept of "compared to sea level". Zhang Nan thought about it and said, "Then it depends on the situation. After a couple of days, my head doesn't hurt, so I will go up. It hasn't been that high for many years.

As soon as the day gets better, the courage becomes smaller. I used to be 4800 trivial, and I can spend the night at that height without any problem! "

Is this bragging?

I didn't say, I have been to Tibetan areas several times in my previous life. Zhang Nan has really stayed in a hotel at such a high place. As for passing by, it is more than 5000 meters many times.

In this life, I am rich and younger, but my courage has become smaller.

Isn’t it just being on a plateau? Bringing oxygen cylinders is afraid of getting a hairy, and it’s not about living on it!
