Located about thirty kilometers south of Iquique, Diego. Alaxena Airport is the second largest airport in Chile and has the longest take-off and landing strip in Chile, and it is precisely because of this airport that the huge Sofia Sweetheart can take off and land here with great conditions.

At two o'clock in the afternoon of this day, Tang Feng, who flew over from Houston, came out of the VIP passage under the protection of more than a dozen bodyguards. At Alaxena Airport, a group of more than a dozen people took four full-size SUVs from the Chevrolet Saabban and began to head north along the road.

The location chosen by Tang Feng this time is located in the northern region of the Atacama Desert. There are two reasons why this place was chosen, one is that according to Tang Feng's understanding, although some people have surveyed this area, they have not found a world-class copper ore vein with large reserves; The second reason is that this position can be a good sweep of Anglo American's five major copper mines in Chile.

Of course, in this area of 780,000 square kilometers, even if other mining companies have surveyed it, this area is too large, and the copper mine can stretch for tens or even hundreds of kilometers like iron ore. A copper mine with an area of more than ten kilometers long and several kilometers wide is enough to be called a world-class copper mine.

And if you want to find a copper mine with only a dozen square kilometers in this seventy or eighty thousand square kilometers of land, for ordinary people, it is not ordinarily difficult, but for Tang Feng, it is just to consume some star core energy.

At this time, Tang Feng, who was sitting in the car, had quietly turned on the survey function of the star core, and in terms of the survey radius of 56 square kilometers of the star core, the widest part of the northern Chilean territory was no more than 200 kilometers. Just walk around and you'll find a suitable spot.

Tang Feng opened the survey function of the star core not to survey for copper mines, but to observe the existence of those areas where there are no exploration wells.

The whole world knows that Chile is a big mining country, so almost all of the world's top mining companies have their own mines in this country. And those mining companies that can't find mines will naturally spend a lot of money. Careful surveying of areas where no large veins have been identified. The focus of this is the 300-kilometre-long and 200-kilometre-wide stretch from Iquique north to the border between Chile and Peru.

In this area, there are many small copper mines, but no world-class copper mines have been discovered, so there are many unbelieving mining companies, have carried out careful surveys in this area, and there are no less than 100 exploration wells alone, but they have not been found. Gradually. There are no major mining companies in this area.

Tang Feng wanted to use the survey function of the star core to avoid the areas that had been surveyed by other mining companies, and then use this area as his base camp, and finally let a world-class copper mine appear here.

Of course, for the sake of mining costs, Tang would not consider the area from Maminia to the north to Kaminia to the east of the line from Codepa. Because these three small cities were built at the western foot of the Andes Mountains, and further east from these three cities is the Andes Mountains with an altitude of more than 3,500 meters. If you want to build a copper mine in that area. Whether it is transportation or mining, the cost will increase significantly.

Tang Feng himself doesn't like base metal mines very much. If this copper mine is turned into a mine with relatively high mining and transportation costs, it will really bury the ability of the star core. Therefore, in the mountainous area east of those three small cities, Tang Feng would not consider it.

In this way, the area that Tang Feng needs to survey is much smaller. Because the area east of the three small cities is only about 100 kilometers wide at its widest point. Tang Feng and the others drove on Highway 5, which was enough to survey this area at one time.

Along the way, looking east from Route 5, the tall and majestic Andes Mountains are in the distance, and between the Andes Mountains and this road. It is an alluvial wasteland. Meltwater from the snow-capped mountains of the Andes Mountains rushes down the slopes of several thousand meters along a river channel hundreds of meters or even kilometers wide, washing the desert into one alluvial wasteland after another.

But very few of these meltwater break through the Atacama Desert, which is only 100 kilometers wide, and in most cases, it is quickly swallowed up by the dry desert, with only a few meltwater flowing down a few rivers and eventually into the Pacific Ocean.

Don't forget, the Atacama Desert is known as the "dry pole of the world", this desert is the driest desert in the world, not even the famous Sahara Desert, much better than here. At the very least, the Sahara Desert can still see rain every year, and in this desert, let alone a year, sometimes it is not uncommon to have no rain for more than ten years or even decades.

This situation has also affected cities located in the desert or on the edges, such as Arica, the capital of the Chilean province of Arica and the northernmost port of Chile, where one of Tang's destinations this time is drought.

Sandwiched between the Pacific Ocean and the Atacama Desert, the northernmost port in Chile, Arica, a city of less than 200,000 people, once had a record of not falling a drop of rain for ten consecutive years.

However, this city in the northwest corner of the Atacama Desert is not as hot as other desert cities, on the contrary, this city is not high latitude, and it is also located on the edge of the desert, the climate is quite good, and it can definitely be called spring all year round.

Aside from the lack of rainfall, the city really can't fault anything else.

Located just on the eastern shore of the Pacific Ocean, the city is the driest city in the world. However, although God closed the door to the rain in the city, it opened another window for the city to obtain fresh water, that is, the foggy weather that reaches more than 200 days a year.

On the city's seashore, it is common to see special "fishing nets" placed high above the sea, which look like fishing nets, but in fact these nets are not used for fishing, but for catching fresh water.

Because Arica is a city full of fog, this fog trap is erected every time there is a foggy day. In fog, this special net can turn the fog in the air into fresh water. A fog trapping net of more than 20 square meters can harvest 170 liters of fresh water a day, which is definitely an environmentally friendly and efficient pure natural pollution-free fresh water collection equipment.

Of course, this kind of fog trapping net can only be used on the seaside, and the entire Arica still relies on the 240-kilometre-long pipeline for its fresh water supply. The pipeline runs all the way to Lake Jongara in the Andes Mountains to the east, providing the city with vital freshwater resources.

Of course, the San José River in Rio will provide some fresh water to the city, but very little. (To be continued.) )
