"Is there really gold in this place? It looks no different from an ordinary riverbed..."

"What, I thought there was really gold everywhere here."

Cao Bianjiao's expedition team bends near the river bank in the north of Saramento, searching for gold on the shallows of the nearby riverbed.

They learned from the last time they were actively attacked by the indigenous people, and searched for a wide-open place on the riverside to build a solid camp with stones. After recapturing the supplies, they had more than 200 bullets. Unless they were forced to fight again by the indigenous people, they would not have the tragic situation that night.

"Do you think gold mines are full of gold ingots? Often 10,000 kilograms of rock gold can extract one or two gold. Gold is free. The gold originally located inside the rock may gradually move to the surface of the rock, and then erode through flowing water to erode into the river channel. Gold is deposited in the river channel to form gold sand. Because rivers often divert the route, there will also be gold sand on the river beach. If gold sand is found on nearby river beaches, it means that there are gold veins on the west side of the Sierra Nevada Mountains in the east."

"In the initial stage of gold rushing, we can use the water flow to wash away lighter sediments, and first collect gold sand from nearby streams and riversides. The second stage is to use high-pressure hoses to perform gold mining operations on the mountainside. The third stage is to dredge the larger rivers, and dredge the river channels to obtain gold sand at the bottom of the riverbed, and then send a large number of workers to dig underground mines to directly mine gold ore." Mineral experts have already made plans for gold mine development before leaving the capital.

"You said a lot of things, I didn't understand. You said there was gold sand here, but why didn't I see it?" a sailor complained.

Before leaving, they heard the rumors of gold everywhere, but they only found a place that was no different from ordinary river beaches.

"Be patient, I haven't complained yet, why are you all shouting?" Cao Bianjiao followed two surviving mineral experts to look for gold mines by the river beach, and had to wade from time to time.

"We can almost confirm that this area is rich in gold, but it is not easy to find a specific location, especially riverbeds with gold mines," said the mineral expert.

They still found nothing in the nearby tributaries and streams.

"Maybe we were in the wrong direction of exploration, we should head to the southern tributary river bank." The mineral experts were marking the nearby topography.

"Is it the southern tributary? It may take some time to get there." Cao Bianjiao said.

Their expedition took another time to come to the southern tributary of the American River and established strongholds there.

And this time they searched for golden sand on the gravel bed river bank and finally gained something.

"That's right, there's a lot of sand and gold here!" The mineral expert found a small piece of golden tough metal fragment on the river beach. The magnifying glass he carried with him made him identify that these were the gold they were looking for!

The sand gold on the edge of the riverbed is just the part where the ore veins are washed out by the river water and rain. There are also many at the bottom of the riverbed, and the most part is the rock gold in the mountains.

Two mineral experts were extremely excited. They found a small piece of sand gold here, which was already very close to their target!

Then the two found many tiny golden sand on the edge of the riverbed and gathered them together, which was quite impressive.

"Golden sand..." The sailors gathered together to look at the golden sand found by the mineral experts, and a bit of fanaticism appeared in their eyes.

When gold and silver become currency, owning gold and silver in human society means having power and status.

"How much gold do you expect in the mountains to be in the eastern region?" a mineral expert asked another companion.

"I estimate that gold mines of all sizes in the entire area can be mined into 10 million kilograms of gold together, and even dredging the river channels in this large area can obtain millions of kilograms of gold." The mineral expert asked answered.

"Hiss...10 million kilograms of gold!" Everyone took a breath of air conditioning.

For them, let alone ten million kilograms of gold, ten million copper coins are wealth that is as rich as a country!

"Of course, it takes hundreds of years of mining to dig out all the gold here, and a lot of manpower and material resources are also required," said the mineral expert.

"Since we have found the location, we should return to Jinshan Town, make more detailed plans and then send people to hunt for gold." Cao Bianjiao was not interested in gold.

This gold was decided by the military headquarters. They were not gold diggers, but soldiers who came to execute orders. It is a death sentence for privately hiding gold, and gold could hardly buy anything in Jinshan Town, which implemented the planned economic system.

"We collect more gold sand to go back as a sample to study, and we also need to look at the distribution of gold sand nearby and the source of the river to calculate the scope of the mining area." The two mineral experts were still unsatisfied.

It took them more than ten days to find a riverbed rich in gold. If they didn't conduct some research, they would always feel a little regretful.

"How much time do you need?" Cao Bianjiao asked.

"Two days...no, three days!" The two mineral experts looked at each other and said.

"I really can't do anything to you. Three days will be three days." Cao Bianjiao turned his head and said to others, "No one is allowed to hide gold privately. He will conduct body searches when returning to the mainland. If I find someone secretly hide gold privately, he will be punished the most severely. If this gold is to enter the treasury, you should know what this means!"

"We understand, Captain, you don't have to always have a bad face after that." The expedition members said.

After experiencing life and death together, they were closer to Cao Bianjiao, and they didn’t need to be so polite to speak.

Li Yizhu helped two Caucasian giant dogs wash the fur by the river and wash away the bloody smell on their bodies. The injured Caucasian dog Xiao Hui was able to move freely, but he walked a little bumpy.

"I didn't expect there was so much gold here. No wonder the military headquarters traveled thousands of miles to let us come here to build Jinshan Town. This is the real purpose of establishing the Jinshan Town stronghold, right?" Li Yizhu also heard the bold speculation made by two mineral experts, and at this time he understood the real purpose of coming to the military headquarters to organize the North American expedition team.

"You know the true intention of the military headquarters. Are you a little disappointed with it? We soldiers need to obey orders to explore, but you volunteered to participate in this expedition." Cao Bianjiao walked over and said.
