readx;??? ps: Thank you for the great reward!

While helping the robot cat sort out the sleeping bag and food, the sparrow explained uneasily:

"You must come back tomorrow night, Maomao, the safety of the fifth brother will be left to you, although I know you...... But ......"

"I'm a card, your kid is the Jade King, who are you staring at when you're not here?"

Wu Di couldn't help it, kicked this kid, didn't the scissors be smashed by the hammer? Who told you not to win two out of three? I play this with your sister-in-law, it has always been a game to win or lose, change to three games and two wins, three games to two wins, and three games to lose five games and three wins, and even once made it a billiards World Championships...... Final!

The robot cat carried a large bag of food and water, looked at Wu Di, who was full of interest, and hesitated:

"Fifth brother, let's take these things to find mines?"

"Hehe, what can compare to your fifth brother's eyes? This is a real eye-catcher! ”

The robot cat nodded, if it weren't really incredible, I would definitely agree with others saying that you have clairvoyance! But what is it at this time, standing still with your eyes closed, if you stretch your arms towards the sky again, is it going to summon the great god?

Every few kilometers Wu Di walked, he had to use the book of heaven to absorb the aura, but this river valley was really not powerful, he had walked for more than three hours, and he didn't find anything!

Guatemala is located in the tropics, known as the land of forests, with more than half of the country being forested. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoBut this is an ancient river channel, except for the big stones are small stones, there is really nothing to see. Wu Di looked at the sky and asked:

"Robot cat, how far have you come? Where to spend the night? ”

The robot cat looked at the GPS in his hand and replied:

"Walked about sixteen or seven kilometers, or shall we rest?" At night, see if you can find a small cave on the riverbank, but it's really not good. Shall we go back? ”

"No, there should be jadeite in this river valley, otherwise there will be no sediment in that mine, let's walk a little more today, and then rest if we can't walk, this half of the river valley has nearly a hundred miles of land!"

The night in the valley was quiet, and both of them wore high-top rubber shoes, mainly for fear of snakes and insects, but this caused their feet to sweat heavily. In the middle of the night, Wu Di finally found a big rock and sat down.

"Grandma, find a place to rest, and if you go on, your feet will be cooked!"

"Okay, fifth brother, you can rest for a while, let me show you a hand."

The robot cat agreed as it removed two snakes more than half a meter long from the package.

"This thing, if you can catch a few when you survive in the wild, it's extremely delicious. It's a pity that we have lost all of our places! You think, there are troops at both ends of three days doing this. This snake breeds like a mouse, and it can't keep up with us! ”

When the sun showed that red face from the east, Wu Di woke up from his sleeping bag and looked at the energetic robot cat that was moving his hands and feet, a little embarrassed. Yesterday it was supposed to be a three-hour standby by one. As a result, he slept until dawn!

"It's okay, we didn't sleep for a few days when we were on a mission! Fifth brother, are you still walking along this river valley today? ”

"Let's go, there's not much left. Since you come here, you are always unwilling not to take a look, maybe the mine is in the mountains at the end. ”

Another morning of walking. Wu Di pointed to a hill on the left and said:

"Judging from the map, you should be able to see Li Dingqier's mine when you climb over this mountain, that guy claims to have hoarded more than 20,000 tons of gem-quality jadeite, or let's find a chance to rob him?"

The robot cat smiled and didn't speak, it's easy to grab it, but you can't carry this thing! More than 20,000 tons of stones, it is estimated that it is enough to build a cemetery, right?

"Hehe, it's good to build a tomb with jade, but I'm afraid that some people will be worried, but the third uncle has made many people have that dream......"

The river valley was rerouted in front of a big mountain, and then it was a really big river, Wu Di shook his head helplessly, it was so difficult that he really wanted to go into the mountain?

"Let's walk back along the side of the hill over there and see if there's anything in the mountain."

The robot cat nodded, although he didn't have any knowledge of prospecting, but he also knew that walking around like the two of them was pure child's play. However, since the fifth brother is willing, it is considered a long-distance training, but the things on his back are much lighter than at that time.

The scenery along the mountain side is much more beautiful than in the river valley, full of unknown wildflowers and shrubs, but the pace of progress is much slower than when you came. The robot cat looked at the distance and used a satellite phone to contact the sparrow, and it will definitely not be able to go back tonight.

Seeing that the moon had crept up the mountain, the forest on the mountain began to become quiet. The robot cat glanced at the dark mountain worriedly, and was about to propose to spend the night in the river valley, when he suddenly found Wu Di stopped and stood there in a daze, his eyes full of surprise.

"What's wrong? Fifth brother? ”

Wu Di shook his head and said:

"Let's go, walk another three or four kilometers, and find a place to spend the night."

This place is about seven or eight kilometers away from the place where Wu Di last used the Book of Heaven to absorb aura, so he habitually verified it with the Book of Heaven again, originally thought that he would continue to trek after trying, but he didn't expect that this time he had a harvest!

Just when he had just let go of the Book of Heaven, thinking that he had nothing to gain and was about to call it a day, in front of the left, about four kilometers away, on the edge of the Book of Heaven's induction, a huge torrent of spiritual energy roared and poured into his body! In an instant, the book of heaven, which had not been noticed for a long time, suddenly came out from a corner of the body, as if it was like a tide-maker, flying up and down in this torrent excitedly, and having fun.

This torrent lasted for a whole minute, and Wu Di judged from the intermittent aura that it should be that the distance that Tianshu could sense was not enough, and this mine was not over yet!

A torrent that lasts a minute, and it's not over yet? How big should that be? And judging from the concentration of aura, this mine is likely to be not only large, but also seems to be of good quality.

Wu Diqiang suppressed the excitement in his heart and walked forward, if that place was not bought, Lan Meng would no longer have to worry about raw materials in the future, and he might even have the ability to hold a few Guatemalan jade public auctions in China!

After walking for more than an hour on the three-kilometer road, Wu Di's clairvoyant eyes could already see the place where he sensed the mineral deposits just now, but why didn't he see the jadeite? Could it be that the distance is wrong?

To his left was a small valley, and to the left of the valley was a small hill with dense forests, which at first glance should not look like a mine. Because according to that kind of aura strength, most of this small mountain bag will be jade ore, where else can any trees grow? It's nice to have grass!

Could it be the mountain behind this mountain? Or is it the underground of the valley?

Getting closer and closer, Wu Di gradually discovered that there is a mine here, but it is not a jade mine, but a gold mine! In the part of the valley near the top of the mountain, and in the lower part of the mountain, which is more than 20 meters deep, it is full of shiny gold-bearing ore! Some of these ores are the same as stones, but you can see a little golden light when you look through them, some of them are simply large golden crystal particles mixed with quartz grains, and some of them are simply a whole golden yellow piece!

Oh my God, this mountain is a mountain of gold! If all the yellow material you see is gold, how many tons of gold can be produced from this large gold mine that almost fills half of the mountain? 10,000 tons or 100,000 tons? How much is that? I don't think the calculator has enough digits......

Calm down, you must be calm, there will not be such a high level of gold in the world, it is absolutely impossible to have all gold here.

The grade of gold in the general industrial value of gold mines is 2-3 g/t, the bonanza is 5-50 g/t, and the extra-rich ore is 50-500 g/t. The Ryoche mine in Kagoshima, Japan, has a gold content of only about 50 grams of gold ore per ton, which is the highest quality gold mine in the world, and it is conceivable that the gold content in the gold mine is very low.

It's hard to know the exact amount of gold by visual inspection, but this place is more than 50 grams in Kagoshima, so there should be no problem, right?

The gold deposits formed by the changes of nature can be roughly divided into three categories: rock gold deposits, sand gold deposits and associated deposits. In the world, the ratio of reserves of rock gold, associated gold and sand gold is approximately 70:15:15. This is a standard rock gold mine.

Gold is sulfur-philic and often closely symbiotic with sulfides such as pyrite, arsenite, galena, stibnite, etc. At the same time, it is also copper-philic, it occupies the edge position between copper-philic and iron-philic elements in the periodic table, and belongs to the same subgroup as copper and silver.

Chalcopyrite is also golden yellow, similar in appearance to gold. Then, the gold in this place should be chalcopyrite as the main carrier mineral.

Wu Di looked at it carefully for a while, and found that the situation did not seem to be as optimistic as when he first saw it, so he must have been dazzled. However, this should also be about 30 grams? Or 50 grams? It's really not good, even 5 grams is fine!

With the current level of metallurgical technology, more than 0.5 g/t has industrial mining value! Wu Di glanced at the veins that were deeply rooted in the mountain, like a wild dragon with earthy brown spots dotted with gold, as if he couldn't see the end at a glance!

No, no! There is pyrite in the carrier mineral of gold, and it seems that pyrite is mostly earthy brown, could it be that most of the earth-brown is gold-containing pyrite? So how to calculate this gold content?

The robot cat saw Wu Di standing there in a daze, with an incomparably rich expression on his face, and couldn't help but cry out worriedly:

"Fifth brother, the cool air on the side of this mountain is too heavy, why don't we go back first and spend the night in the river valley......"

Haha, by the way, go back first, go back first to win the mining rights of this mountain range, and then find professionals to explore the reserves, even if you mistake the chalcopyrite for a gold mine, looking at this vein that is deeply rooted in the mountains, you will not lose money, right?
