Soon, Shuichi Minamino took a closer look through the eyes of perspective, and after some observation, he found that the width of this kimberlite rock is about 1.6 meters, and the length is about 0 kilometers!

"This is already a medium-to-large diamond rough! Such a medium to large vein should bring me a lot of money! During this time, he read a lot of books about mineral resources, and he knew that a vein of this size was indeed a large and medium-sized diamond vein.

The thickness of the kimberlite rock wall is small, generally less than a meter, but the length is large, up to 65 kilometers, and the appearance of groups constitutes a group of rock walls, and a few are ring rock walls. Kimberlite beds, kimberlite craters, crater lakes, and volcanic deposits are rare. The geological age of kimberlite formation, from the continuation to, as far as the world is concerned, is mainly formed in the late period, but in a considerable size of the kimberlite belt or area is often multi-aged.

That's what makes rough diamond rock special, it's not like iron ore, gold or silver ore and so on. Its width is small, often less than two meters, but its length is very long, the longest being tens of kilometers long.

Shuichi Minamino estimates that the veins that caused this strange ore are mainly caused by the compression of the strata.

You think, diamonds are all hard, they are all compressed by the formation. That's why the diamond vein is very long, tens of kilometers long, but its width is less than two meters wide, which is probably the reason for such a small width caused by stratum compression.

"This diamond vein should allow me to mine for twenty or thirty years." Shuichi Minamino said secretly in his heart. Diamond veins are very difficult to mine, after all, diamonds are hidden in kimberlite, and you have to mine these rocks and break them to get a powerful diamond, which is a diamond.

He remembers that there is a world-famous diamond vein in South Africa, "Premir", which was discovered in 190, and since the rock tube was put into production in 190, 78 million carats of diamond have been mined by the end of the 70s of the last century. The tube has also produced many famous large diamonds, such as the largest gem diamond, the "Cullinan". There are also more than 1,000 kinds of diamonds in the rock tube, and the quality of the diamonds is very good, with gem-quality diamonds accounting for about 55%. Since the middle of the 19th century, South Africa has replaced Brazil as the world's main source of diamonds.

It can be said that this famous diamond vein is absolutely rare in the world. Because the diamonds it produces are of good quality!

Not all rough diamonds are jewelry-quality diamonds. On average, only 0% of the diamonds mined are gem-quality, while the other 80% can only be used in industry. To get a rough 1 carat diamond, you need 50 tons of kimberlite, and you can only end up polishing a diamond with about 0 to 50 points.

That is to say, only 0% of the diamonds produced by the general diamond veins can be used as raw materials for jewelry, and 80% of the diamonds can only be used for industrial materials, such as for cutting glass, for cutting machines, etc.

"I'll give you a name, it's the Sierra Diamond Vein!"

After recording the marks on the map, Shuichi Minamino hurried back to the capital of Nigeria non-stop, because he was in a hurry to buy the land. In the future, he can develop whenever he wants!

On this day, Abbala was drinking coffee in his office, but his secretary called and said that Shuichi Minamino had come to him. He immediately refreshed himself when he heard it. In the past two months, Minamino Shuichi has asked him to buy land three or four times, and he himself has also obtained a lot of 'personal' income. Now Lin Lin has received a total income of 500,000 US dollars, and at the same time, the other party has also given two customized versions of cars produced by Nanye Automobile. Anyway, his current good impression of Shuichi Minamino is very good.

"Mr. Abubarah, we meet again. I'm sorry to take the liberty of bothering you. Minamino said with a smile when he saw Abbara.

The last time he discovered two new oil fields, he also asked Abu Bala to buy land, and the process went smoothly.

"I'm here to buy a new piece of land." Shuichi Minamino said what he meant.

"Really, where has Mr. Minamino been taking a fancy to lately?" Abu Bara Dao.

At present, Nigeria is still very welcoming to foreign investment in mining mineral resources, so there will be no more restrictive things like in the coming decades. At least for now, it's still very rich.

Besides, Nigeria still relied on mineral resources to develop in the future, although in the middle of the year because of the fear that the mineral resources will be occupied by others too much, began to implement a restrictive policy, but in the end in the later stage still chose to open up to attract investment. Because Nigeria finally found that they still have to rely on foreign capital to develop their economy!

So now that Minamino Shuichi is coming, it actually brings a lot of economic impetus to the local area.

After all, he first taxed, bought land, hired local labor, drove related industries, etc., all of which belonged to the economy and played a certain role.

"I've got my eye on it." Shuichi Minamino pointed on the map.

Abu Bala saw that the place belonged to the wilderness. It's really not a hassle to buy a place like this. Soon, the deal was done.

Shuichi Minamino gave Abu Bala some benefit money again, and then invited him to a big meal, and then went back to their respective homes to find their own mothers. Anyway, the 'benefit fee' is a good thing to use everywhere.

South Bay Oilfield.

"Minamino, why are you so happy lately?" Loki asked Minamino quizzesically.

"It's just a good mood." Minamino Xiu smiled and said, would he tell the other party that he had discovered two new oil fields and a diamond vein?

Shuichi Minamino has already planned that the two new oil fields, namely the Ohno Oilfield and the Masano Oilfield and the Sierra Diamond Vein, are going to be mined by himself. Because in the future, he will discover more and more oil fields and other mineral resources. He plans to open his own mining company when he goes back this time!

"Why haven't you returned to Tokyo yet? You're here and you have nothing to do. Loki asked, puzzled. The main reason why he stayed here was because the South Bay oil field was just getting started, and he needed to stay and direct the work.

"It's okay, I'll just stay here and talk about it!" Minamino Shuichi. In fact, he stayed here to continue to look for various mineral resources such as oil fields, gold mines, diamond veins, etc.! Wait until he's found a certain level before going back. Now he has set a small goal - to find enough mineral resources worth 10 billion yuan here first!
