Happy Tycoon

"**, do we want to go down? The ground sent me an inquiry, asking about our destination." Adrian turned his head and asked Yang Jing.

Although Papua New Guinea is poor, except for the regular airport towers in several major cities, most airports in other places are airstrips, and there is not even a tower. Therefore, if you rent a helicopter in Papua New Guinea, you hardly need to contact the local air traffic control department. Filing and application.

　　 There is also only an airstrip here in Porghera, but after all, it is the location of a gold mine, and Rio Tinto and BHP Billiton, the two mining giants, jointly control this, so there is still an air traffic control here.

　　 Yang Jing thought for a while and turned his head and said to Guo Xiaoxiang: "Why don't you go down and take a look? I have never seen how this kind of open-pit mine is mined."

　　 Guo Xiaoxiang shrugged his shoulders and said indifferently: "Whatever I want."

　　 So Yang Jing nodded at Adrian, motioning them to fly down and stop.

　　 Looking down from the air, the entire Borghera is divided into two parts, one is a residential area, and the other is a mining area with a larger area. It is worth mentioning that the mining area has an altitude of more than 2,300 meters, but the huge main pit is more than 600 meters deep. That is to say, because of the pit, the average altitude of the mining area has been stretched. A lot lower.

　　 And to the west of the mining area is a mountain with an altitude of more than 3,000 meters. In addition, the largest mine pit has been dug down to six or seven hundred meters, making the mining area look extremely dangerous.

The residential area is to the east of the mining area, on both sides of a simple road that stretches for several kilometers. There are a large number of scattered houses. Most of these houses are where the miners live. As for the center of the residential area, a small town.

　　In the beginning, Chris asked to land in the mining area so that they could directly visit the mining area. As a result, the air traffic control did not agree, and Yang Jing and the others could only land in the north of the small town of Borghera.

　　 At this time, the rain in the sky has stopped, and the air is full of dense moisture, which makes people feel very slimy and uncomfortable. But fortunately, the altitude of this place is relatively high, and the sun cannot be seen in the gloomy sky, so the temperature is still relatively low, unlike the sauna days in most areas below that are unbearable.

　　 The town is very quiet. A road winding from the east has turned several bends and stretched into the depths of the town.

　　 As a mining expert hired by the company, Liu Zhaoming is very familiar with PNG, especially the major mining areas in PNG, he has visited.

"Dong Yang and Mr. Guo, this small town and the surrounding houses are a town developed on the basis of the Borghera mining area. It has a population of about 20,000, most of which are workers and their families in the mining area. This road was built from Mount Hagen and is the main national highway of Papua New Guinea."

　　 "Ms. Liu, why are you so familiar with this place?" Yang Jing was also curious about how this gentle middle-aged man was so familiar with this place.

Liu Zhaoming said: "In fact, the year before last, I visited this mining area for a period of time with an investigation group organized by a certain department in China. At that time, I lived here for more than 20 days, so it is still a comparison here. Familiar. But now it's been two years, the town doesn't seem to have changed much."

　　 "Yeah, Teacher Liu, have you ever inspected here?" Yang Jing was quite surprised, "Then Teacher Liu, what do you think about this place?"

"Views? Hehe, what can you think of?" Liu Zhaoming smiled and shook his head as he walked. "If you have any views, then you can only say that God cares too much about this country. Just like this gold mine, Mr. Yang, you Guess what the average grade of gold ore in this mining area can reach?"

　　 Although Yang Jing doesn't understand very professional mining knowledge, he is now a major shareholder of Rongbao Mining, so he has also learned a lot of mining knowledge by himself in the past two years, and he still understands some basic terms.

　　 "Can it exceed 1 gram/ton?" Yang Jing thought for a while, guessing a higher number and said.

　　 This number is definitely high for the average grade of a gold mine.

　　 Generally speaking, the industrial grade of gold ore is generally 03-05 g/ton, which means that if the gold content in the ore reaches 03-05 g/ton, the ore can be mined and profit will be generated. With the development of dressing and smelting technology or the increase in the price of mineral products, the minimum industrial grade of ore will be lowered.

　　 At present, the average grade of many gold mines in China will only be able to reach the standard of 03 g/ton, while the average grade of some famous gold mines in the world is mostly below 1 g/ton. For example, the copper-gold mine with the largest gold reserves in the world, which is also located on Illian Island, is less than 700 kilometers away from the Bolghera gold mine. The average grade of its gold ore is not good. Only 0703 can/ton.

　　 The Olympic dam uranium-copper-gold mine in Australia, which ranks second in gold reserves in the world, has an average gold ore grade of only 0328 g/ton.

　　 In addition, the world's third-ranked copper-gold mine, located in the Fibo Mine in Alaska, USA, has an average gold ore grade of only 035 grams/ton.

　　 However, these three top three largest mines in the world are all associated with multiple metals, and gold ore is just one of them. Even if the gold reserves of these large mines are more than 2500 tons, gold is only one kind of output of these mines, and more mineral products of these mines include other associated mines such as silver, copper, and molybdenum.

　　 But even so, the average grade of gold ore in this associated mine can exceed 03 g/ton, which is definitely very good.

So Yang Jing guessed a 1 gram/ton. He already thinks that the guess is not low. After all, the Borghera gold mine is a silver-gold associated mine. In addition to having more than 400 tons of gold reserves, there are more than one Thousand tons of silver reserves.

　　 Liu Zhaoming smiled and shook his head and said, "Dong Yang, you guessed it a bit low."

　　 "Huh? Is this still low?" Yang Jing couldn't believe it.

"Yes, the number you said is really a bit low. I have a set of numbers here, listen to it. The Polghera gold mine was built and put into operation in 1990, and it has been in production for 28 years. From 1990 From the beginning of production in 2015 to 2015, this gold mine produced a total of 19.36 million ounces of gold, which is about 602 tons of gold. Now the gold mine still has 400 tons of gold reserves. The remaining gold reserves of the gold mine currently remain. This gold mine has been in production for 28 years, and the average gold ore grade of the entire gold mine is as high as 44 grams/ton."

　　 This figure made Yang Jing and Guo Xiaoxiang take a breath. Guo Xiaoxiang asked incredulously, "Mr. Liu, does this gold mine really have such a high average grade?"

Liu Zhaoming nodded and pushed the glasses on the bridge of his nose. "When I came to investigate the year before, I learned that the highest grade of gold ore in this gold mine actually exceeded 726 grams/ton, which scared me. Jump. But I have to admit that whether it is the Porghera gold mine or the Glasberg copper-gold mine to the west of this gold mine, it is a huge wealth that God has bestowed on this island."

After a pause, Liu Zhaoming continued: “In fact, the average grade of gold ore in the two largest gold mines in Papua New Guinea is very high. It is as high as 2732 g/ton. In other words, if we can find another gold mine or an associated mine such as a copper-gold mine, then the gold ore grade in it will certainly not be too low."

　　 Liu Zhaoming's words reminded Yang Jing of the flash of bluish-green light that he saw from the mountain range when he was about to arrive in Borghera. Although just glanced at it without carefully observing it, but in the sense that the turquoise light that appeared in the mountain range did not seem to be any worse than the turquoise revealed by the Borghera gold mine.

　　 Could it be that there is also a gold mine that is similar to this Borghera gold mine?

　　 Thinking of this, Yang Jing asked Liu Zhaoming: "Teacher Liu, then you said, if another gold mine can be found in the Mahler Mountains, would it be of high grade?"

Liu Zhaoming groaned and said, “I’m not quite sure about this~www.readwn.com~ But according to the reason for the formation of the Porghera gold mine, I have a seven-point assurance that I can be sure if it can really be in MAHLE. If another gold mine is found in the mountains, its grade should be about the same as the Borghera gold mine."

Liu Zhaoming pushed his glasses and pointed to the surrounding mountains and said: "The Borghera gold mine is located in the New Guinea orogenic belt. The orogenic belt is located on the northeastern edge of the Australian plate, which is composed of the Indo-Australia plate, the Pacific plate and a series of other small plates. Such as the boundary between the Caroline plate and the Philippine plate. The orogenic belt began to form after the Triassic-Jurassic period, and experienced a series of arc-continent collisions in the Mesozoic and Cenozoic, forming the current form of the orogenic belt In other words, Borghera is a typical shallow-formed low-temperature hydrothermal deposit. In this area, once gold deposits can be found again, it will be almost the same low-temperature hydrothermal deposit as the Borghera gold deposit. "

　　 Liu Zhaoming said a lot of professional terms. Although Yang Jing didn't understand much, but looking at Liu Zhaoming's confident expression, Yang Jing knew that what he said was true.

　　 This Liu Zhaoming is a real mining expert invited by Guo Dabao from Huaxia University of Mining and Technology. Since he dares to say this, he is confident enough to prove that these things he said are not groundless.

　　 That is the case, after visiting this gold mine, I will go back to the area with turquoise light that I discovered just now!

　　 In case a gold mine of the same level as the Borghera gold mine is discovered, then Rongbao Mining can re-enter a precious metal mine with huge profits!

　　Ps: Bow to thank you for the reward of "Shaking the World" 500.
