In fact, Xuanyuan's dream of becoming a super-rich man did not wait for a year later, to be exact, after more than 20 days, his dream came true.

When Tang Feng told Tou'er the specific scope of the survey and promised to carry out the survey at any cost, the Tou'er immediately stopped all the commissions of other companies at hand, and summoned all the employees of the Explorer Company to the St. Lawrence Valley Forest Farm and began the tedious survey work.

Now there are more than 30 people in the Explorer Company, and it is actually very easy to deal with this 30 square kilometers of exploration area, and a week later, the team led by Clark found a large porphyry copper mineralization zone in the middle of the mountains on the west side of the St. Lawrence Valley, which immediately attracted the attention of the entire Explorer Company.

The leader decisively mobilized all the others to the mountains on the west side of the St. Lawrence Valley, and began to focus on the eastern foothills of the fifteen-kilometer-long mountain range, and the center of gravity of the survey was the eastern foothills of the mountain range and the valley floor of the St. Lawrence Valley.

Then, after more than a week, an extremely detailed survey data was placed in Tang Feng and Xuanyuan and Hugo. In front of Sigman.

Based on initial surveys, a zone of porphyry copper mineralisation has been identified in the western range of the St. Lawrence Valley and parts of the valley. The mineralized zone strikes north-south and the main metal minerals are bornite, chalcopyrite, chalcocite, arsenic chalcopyrite, chalcopyrite, sulphur arsenite and mirror ironite.

The ore body is divided into the upper leaching zone, the oxidation zone, the middle secondary enrichment zone and the lower primary sulfide ore zone. There are limonite in the leaching zone, malachite, water gallium and other minerals in the oxide ore belt, with a copper grade of about 1%, accounting for about 20% of the total ore reserves.

The secondary enrichment zone is bornite, chalcopyrite, chalcocite and a small amount of copper blue, containing 2%-8% copper, with an average copper content of 4%, of which bornite accounts for 70%, chalcopyrite accounts for 20%, chalcoccite accounts for 5%, and the rest is pyrite and copper blue. Primary sulphide ore has been controlled to a depth of 400 metres, with the main useful minerals being chalcopyrite and pyrite, with an average containment of 0.8% copper, but with small reserves.

With a total length of approximately 12 kilometres and a width of 1,500 metres, the entire orebody has an average contained content of 4.2% copper and 0.036% molybdenum at a cut-off grade of 350 metres, with reserves of more than 4% copper ore estimated at more than 1.2 billion tonnes. The copper reserves of the entire ore body are estimated to be more than 50 million tons!

Although these data are somewhat different from the copper mine that Tang Feng brought over, don't forget that this is only a preliminary survey result. In this world, there is no survey company that can compare the data measured by the star core.

But even so, this data still surprised everyone, and of course, after the surprise, it was laughter and a grand celebration.

What does a copper mine with 50 million tons of copper reserves mean? There was only one word in the minds of everyone present - the world's first!

That's right. If the results of this survey are correct, then the St. Lawrence copper mine can definitely surpass the current world's largest copper mine, the Eggundida copper mine in Chile.

You know, Chile's Esgundida copper mine has copper ore reserves of up to 4.16 billion tons, with an average grade of 0.76%, and the total copper reserves are as high as 31 million tons, which is already a stunning number, but the copper reserves of the Esgundida copper mine are compared with the St. Lawrence copper mine, both in terms of copper ore grade and total copper reserves. That's far from it.

With reserves of more than 4% copper, there are already more than 1.2 billion tonnes of copper ore, which means that the cost of mining at the St. Lawrence copper mine is much lower than that of the Eggundida copper mine.

You must know that the newly developed copper mines in the world are now rare to have copper mines containing more than 1% copper, and the copper mines that reach 4% are the kind of old copper mines that have been mined for decades or even hundreds of years. The average grade of the Eggundida copper mine is only 0.76%, but how much does it cost to mine? 60.8 cents/pound copper! This is currently the lowest cost copper mine in the world. And what are the costs of mining the St. Lawrence copper mine, which has a much higher copper ore grade than the Esgundida copper mine?

According to the initial survey of the St. Lawrence copper mine, this copper mine has leaching and oxidation zones in the upper layer. But these two layers of basically useless ore layer is not very thick, plus the upper layer of soil layer, the whole thickness is only more than 30 meters, so even if the upper layer of useless soil layer, leaching belt and oxidation zone are all removed, the cost required is evenly distributed to the mining cost of the whole mine, it is also very little.

And once the upper layer of useless ore layer and soil layer are all eliminated. Mining copper ore from the central secondary enrichment zone alone would be enough to reduce the mining cost of the entire copper mine to less than 50 cents/pound of copper, and if you add in processing fees and other expenses, the cost of pure copper from this copper mine will not exceed $2,000 per tonne! This cost is already more than 20% less than the cost of pure copper produced at the Esgundida copper mine!

You must know that a few years ago, when the copper price was maintained at 65,000 yuan per ton, the profit of a ton of pure copper by domestic copper processing enterprises in China could reach more than 30,000 yuan. Almost 100% profit!

Even if the international copper price now plummets to the level of US$5,600/ton in a few years, the cost of pure copper at US$2,000/ton is frighteningly low enough. If this cost is changed to the highest international copper price in 09, it is almost 300% of the net profit!

Even now, there is more than 150% net profit! This price is definitely the highest in the world!

And with 48 million tons of copper reserves, how valuable is this copper mine if calculated according to this ton of copper profit? Even if the net profit of a ton of pure copper is only $3,000, the net profit of this copper mine is more than $140 billion!

This figure definitely deserves a laugh from everyone in the scene, especially Hugo. Sigman, 8% of the copper mine's equity is also a net profit of more than 10 billion US dollars!

Invested 150 million US dollars, which is less than a month, and it has directly increased by more than 60 times, is there anything crazier in the world than this kind of investment? What to rob in comparison. Banks, Google, Facebook, all of them are weak! It's definitely a crazy investment.

(PS: This figure is not very accurate, but the data of the blister copper mining cost and pure copper cost of the Esgundida copper mine is true, and our mine must be lower than the Esgundida copper mine!) Data emperor or something, don't pursue it, let's this is a YY novel)

Hugo. It was only at this time that Sigman admitted that Tang Feng was really extraordinary, and as the richest man in Argentina, he was also deeply happy about his original choice. This is just a forest farm covering an area of 30 square kilometers, and there are thousands of square kilometers of land under its name, so how much should it be worth if mineral deposits are found on these lands?
