Kim is such a wonderful thing, and whoever has it becomes the master of everything he wants. With gold, even the soul ascends to heaven. —Christopher Columbus

According to the United States Geological Survey (USGS), the world's current available recoverable reserves of gold in the Earth's lithosphere are estimated to be only about 37,300 tons.

Since ancient times, human beings have mined and refined 90,000 tons of gold, of which about 10,000 tons have been made into various gold tools that have been scattered in all corners of the earth, and only about 80,000 tons exist, and the unmined and smelted gold accounts for less than half of the existing amount.

It can be seen that gold has become a rare resource on the earth.

According to the modern mining rate, gold is likely to be mined and depleted on the earth within 100 years, and it will be almost impossible for humans to find gold from the earth at that time.

The scarcity of this vein has led directly to the boom in the global gold market.

After all, there is so much gold, it will be gone after mining, buy a little now, or a little tun, the future will be a rare metal, gold can be passed on endlessly, not changed by war or government, as long as human beings can not invent the element change, then the value of gold will always exist.

Before Jiang Yin inspected the world's ore veins in the Great Song Dynasty, he also specially investigated the amount of modern gold mining.

In modern times, most of the unmined gold is distributed in natural gold mines at home and abroad, South Africa accounts for 60~65%, Russia accounts for 20%, and the United States and Canada account for 10%.

Gold deposits are divided into two categories: mountain gold and placer gold. Mountain gold is the primary gold, South Africa, Canada, the United States and other countries are mined from hard stone and processed and beneficiated.

Placer gold is mostly found in the sediment of rivers. The world's largest natural gold ore was recently discovered in central Brazil, where it weighs about 1t, surpassing the 272kg "mountain" nugget found earlier in Australia.

In the modern world, the annual production of gold is about 4000t. The main foreign gold producing countries are: South Africa, the former Soviet Union, Canada, Brazil, the United States, Ghana, Papua New Guinea, Zimbabwe, the Philippines, Austria, Colombia, etc.

South Africa and Russia account for about 55% and 30% of the world's total gold production each year, with South Africa mainly producing gold in the Waal River basin, a tributary of the Orange River. There are more than 60 gold mines here, with mines up to 3,000m deep and temperatures above 40°C, which, together with foul air and stagnant water, make the work of gold miners arduous and dangerous.

Once the ore arrives at the factory, it has to be crushed, screened, melted, and refined to obtain pure gold. Johannesburg is the centre of South Africa's gold mining industry, and the Rand Refinery is the world's largest gold processing plant, producing 280 tonnes of gold per year. More than 10% of the gold used in the entire Western world is smelted from this factory.

Over time, more and more gold mines have been depleted in modern times, and countries have begun to focus on gold reserves, and the American economist John Maynard Keynes once said that "gold plays an important role in our system." It serves as a last guard and reserve in times of urgent need, and nothing else can replace it. ”

Therefore, some people also evaluate that gold is the last credit support for a country's currency, and the last guarantee against the collapse of the national currency.

This last barrier is enough to see the importance of gold to various countries.

Therefore, when there is an opportunity to buy gold at the market price, the government also hopes to store more gold, after all, gold can be used to balance the balance of payments, maintain or affect the exchange rate level, and at the same time, it has a special role in stabilizing the national economy, curbing inflation, and improving international credit.

The gold market is a real supermarket.

Melbourne's mine production is stable at around 150 tonnes a year, which is already a considerable output, but it is still not enough to be satisfied with the expansion of Tianchen Group.

After all, all the capital created by Tianchen Group will eventually serve the New Song Dynasty, and any thing that spends money will be a huge expenditure once it rises to the level of the country, no matter how small the country is.

And the new Song Kingdom, is in need of large-scale modernization and expansion, the capital required is very huge, Jiang Yin budgeted, now the large ore veins in his hands are only enough for two cities to renovate, if you want to renovate the city, you must mine new mines.

But to mine new mines, there is simply not enough manpower, if you recruit miners from modern times, then the profits of gold and silver mines will make everyone crazy, if modern people because of these interests, quietly Jiang Yin's news of crossing, or evidence revealed, Jiang Yin believes that the next day he may lie on the operating table of the national dissection room and be studied like a guinea pig.

Despite the ability to teleport, Jiang Yin is also an invincible existence in the mind space, but more is better than less, and Jiang Yin doesn't want anything to happen.

Therefore, regarding the mining of rare metal veins, there are not many modern people he uses, and all the people who mine are the Great Song people, and those Song people who sent troops to attack him and were captured are the most assured miners he uses.

Mining is untechnical, but it is indispensable for Tianchen Company and the New Song Dynasty, and without using modern people, you can only choose to use people from the Song Dynasty to mine.

However, the Song people have been used to surrender the army, and the mining capacity is still too weak, and Jiang Yin needs more labor to achieve the great rejuvenation of the new Song Kingdom.

Thinking about it this way, Jiang Yin had a super bold idea......

........

"White Slave Trade" Cai Changyi saw the plan handed to him by Jiang Yin, and the expression on his face was very exciting.

"Jiang Shao, I've only heard of the black slave trade, what the hell is this white slave trade?" Cai Changyi swallowed and asked.

"Lao Cai, the new Song Kingdom is going to develop, and Tianchen Company is also going to grow, don't you say?" Jiang Yin didn't answer directly, but asked a completely irrelevant question.

"Yes," Cai Changyi nodded honestly.

"The modern gold market is booming, and the price of gold has risen to $60 a gram, right?" Jiang Yin asked again.

"Yes, our domestic price is now stable in the range of 365 yuan to 390 yuan, I am more optimistic about the gold market, now the diamond business is not good, with the increase in the mining of Melbourne gold mines, we can transfer the main business to the gold business."

"That's exactly what I meant." Jiang Yin clapped his hands and said, "But not only do I continue to mine in Melbourne, the progress of gold mining there is already saturated." ”

"Hmm...."Cai Changyi immediately understood what Jiang Yin meant, "Jiang Shao, what do you mean, go catch some white people and go to the deserted new mines?" ”

"Bingo" Jiang Yin snapped his fingers, "Don't those white people in Europe like to enslave blacks, this time, let's try to replace them with enslavement....."
