Chapter 565 Borghera Gold Mine
"Boss, do we want to go down? The ground sent a message asking about our destination." Adrian turned around and asked Yang Jing.

Although Papua New Guinea is poor, except for a few big cities that have regular airport towers, most of the airports in other places are airstrips without even a tower, so there is almost no need to report to the local air traffic control department when renting helicopters in Papua New Guinea. Registration and application.

There is also only one simple airport here in Borghera, but after all, this is where a gold mine is located, and it is jointly controlled by two mining behemoths, Rio Tinto and BHP Billiton, so there is still air traffic control here.

Yang Jing thought for a while, turned his head and said to Guo Xiaoxiang: "Why don't you go down and have 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, I can do whatever I want."

So Yang Jing nodded at Adrian, signaling them to fly down and dock.

Looking down from the air, the entire Porgera is divided into two parts, one part is the residential area, and the other is the mining area with a larger area.It is worth mentioning that the altitude of the mining area is more than 300 meters, but the depth of the huge main pit is more than 600 meters. few.

Moreover, to the west of the mining area is a mountain with an altitude of more than 3000 meters. In addition, the largest mine pit has been dug down to a depth of 700 meters, which makes the mining area look extremely steep.

The residential area is in 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 miners live. As for the center of the residential area, it forms a small town.

At first, Chris requested to land in the mining area, so that BOSS and the others could go directly to visit the mining area, but 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 had stopped, and the air was filled with thick humidity, which made people feel very sticky and uncomfortable.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 unbearable sauna days in most areas below.

The town is very quiet. A road that winds from the east makes several turns and stretches into the depths of the town.

As a mining expert hired by the company, Liu Zhaoming is very familiar with Papua New Guinea, especially the major mining areas in Papua New Guinea. He has visited all the major mining areas.

"Mr. Yang and Mr. Guo, this town and the surrounding houses are a town developed on the back of the Borghera mining area. It has a population of about [-], most of whom are workers and their families in the mining area. The first road was built from Mount Hagen, which is the national backbone road in Papua New Guinea."

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

Liu Zhaoming said: "Actually, the year before last, I visited this mining area with a delegation organized by a certain domestic department. At that time, I lived here for more than 20 days, so I am quite familiar with it. Yes. But it’s been two years now, and the town doesn’t look like it’s changed much.”

"Yo, Mr. Liu, have you visited here before?" Yang Jing was quite surprised, "Then what do you think of this place, Mr. Liu?"

"Opinion? Hehe, what's your opinion?" Liu Zhaoming shook his head with a smile as he walked, "If you have an opinion, it can only be said that God has favored this country too much. It's like this gold mine, Mr. Yang Guess what the average gold ore grade in this mining area can be?"

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

"Can it exceed 1 gram/ton?" Yang Jing thought for a while and guessed a relatively high number.

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

Generally speaking, the industrial grade of gold ore is generally 0.3-0.5 g/t, that is to say, if the gold content in the ore reaches 0.3-0.5 g/t, the ore can be mined and will generate profits.With the development of dressing and smelting technology or the increase of the price of mineral products, the minimum industrial grade of ore will be reduced.

At present, the average grade of many gold mines in China will only be able to reach the standard of 0.3 g/t, while the average grade of some famous large gold mines in the world is mostly below 1 g/t.For example, the copper-gold mine with the largest gold reserves in the world is the Grasberg copper-gold mine, which is also located on Irian Island and less than 0.703 kilometers away from the Borgera gold mine. Only [-] 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 0.328 g/t.

In addition, the world's third-ranked copper-gold mine, the Fibo mine in Alaska, USA, has an average gold ore grade of only 0.35 grams per ton.

However, these three world-ranked top three large mines are all associated mines of various metals, and gold ore is only one of them.Even if the gold reserves of these large mines are more than 2500 tons, gold is only a kind of output of these mines, and more mineral products of these mines include silver, copper, molybdenum and other associated minerals.

But even so, the average grade of gold ore in this associated ore can exceed 0.3 g/t, which is definitely very good.

So Yang Jing guessed a 1 gram/ton, and he already thought that the guess was not low. After all, the Borghera gold mine is a silver-gold associated mine. In addition to having more than [-] tons of gold reserves, there are also more than one Thousand tons of silver reserves.

Liu Zhaoming shook his head with a smile and said, "Director Yang, your guess is a bit low."

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

"That's right, the number you mentioned is really a bit low. I have a set of figures here. Listen to me. The Borghera Gold Mine was completed and put into production in 1990, and it has been in production for 28 years. From 1990 From the beginning of production in 2015 to 1936, this gold mine produced a total of 602 million ounces of gold, which is about 28 tons of gold. Now the gold mine mentioned outside still has 4.4 tons of gold reserves. The current remaining gold resource reserves of this gold mine. This gold mine has been in production for [-] years, and the average grade of gold ore in the entire gold mine is as high as [-] grams per ton.”

This figure made both Yang Jing and Guo Xiaoxiang gasp. Guo Xiaoxiang asked in disbelief, "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 inspect the year before last, I learned that the highest gold ore grade in this gold mine exceeded 72.6 grams per ton. I was also shocked at that time. Jump. But I have to admit that whether it is the Porgera gold mine or the Grasberg copper-gold mine to the west of this gold mine, they are all great wealth bestowed on this island by God.”

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. Even the Lihir Island copper-gold mine located in Lihir Island has an average gold ore grade As high as 2.732 g/t. That is to say, 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 definitely not be too low.”

Liu Zhaoming's words reminded Yang Jing of the flickering turquoise light he saw from the mountain range when he was about to arrive in Borghera just now.Although I just glanced at it and didn't observe it carefully, I felt that the turquoise light in that mountain range was no worse than the turquoise light revealed by the Borghera gold mine.

Could it be that there is also a gold mine in the same situation as this Porgera gold mine in that place?

Thinking of this, Yang Jing asked Liu Zhaoming: "Mr. Liu, tell me, if another gold mine can be found in the Mahler Mountains, will it be of high grade as well?"

Liu Zhaoming pondered for a while and said, "I'm not quite sure about this, but according to the reason for the formation of the Borghera gold mine, I'm [-]% sure. If it is a mine, its grade should be similar to that of the Porgera gold mine."

Liu Zhaoming pushed his glasses, pointed to the surrounding mountains and said: "The Porgera gold mine is located in the New Guinea orogenic belt. This orogenic belt is located on the northeastern edge of the Australian plate. It is the Indo-Australian 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, and experienced a series of arc-continent collisions in the Mesozoic and Cenozoic, forming the current form of the orogenic belt That is to say, Porgera is a typical epithermal deposit. In this area, once gold deposits can be found again, it will be almost the same low-temperature hydrothermal deposit as the Porgera gold deposit. .”

Liu Zhaoming babbled 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 was a real mining expert invited by Guo Dabao from Huaxia University of Mining and Technology after a lot of effort. Since he dared to say that, he was sure enough to prove that what he said was not groundless.

Since this is the case, after visiting this gold mine, turn around and go to the area that revealed the turquoise light that you just discovered!

If a gold mine of the same level as the Borghera gold mine is found, then Rongbao Mining can enter another precious metal deposit with huge benefits!
