Gu Qi, she just wants to farm

Chapter 648 Mining

Three days later, a group of people changed into ordinary clothes and walked into the mountain from the mountain road behind a warehouse. The old man Han was too old to be included in this trip. This time, the Han family followed Han Si and the old man beside him. One guard, while Gu Qi brought Li Changshun, Zhang Peiwu and three masons.

Mineral prospecting technology in this era is limited, because it is impossible to use metal instruments for actual surveying, so the stone workers in charge of prospecting have a formula of experience for prospecting:

"On a mountain, there is ocher on top, and iron below it; on top of lead, there is silver below; on top of cinnabar, there is gold below; on top of a stone of kindness, there is copper and gold below, and on top of mausoleum stone. , there are lead, tin, and red copper below." This formula is also known as the six arts of Guanzi.

The ocher that villagers picked up on Dazhu Mountain before is hematite, which is associated with iron ore during the metallogenic period. The more ocher exposed on the surface of the mountain, the size of the iron ore below the mountain can be almost determined.

Two hours later, several people walked to a place with few vegetation. Zhang Peiwu and three masons removed the sand and miscellaneous rocks on the surface, and soon everyone saw a red rock formation.

"It's ocher!" Zhang Peiwu's face showed joy. Although he was not a mason, but in order to forge famous swords, he traveled all over the mountains with his master when he was young, and he was no stranger to mining.

Soon several masons cleaned up the grass, trees, and rocks within a hundred steps, and a large red rock formation was exposed in front of everyone. The faces of the three masons were flushed: "Boss, this hematite mine occupies a lot of land."

"Speak down." Zhang Peiwu reminded.

When going up the mountain, the masons brought prospecting tools and used the most basic excavation method. Several people worked together to strip off the topsoil and thin rock layers, and after digging a few feet, they found iron ore.

"How is it?" Gu Qi turned around and asked Zhang Peiwu.

"The iron content is at least [-] percent."

In fact, a lot of red mines have been discovered in Dakang, but most of them are low-to-medium minerals. Nearly half of the mines can extract less than half of the iron sand from the iron ore. Among the medium-sized iron mines mined, the iron content can reach more than [-]%, and there are only two places, most of which are between [-]% and [-]%.

If the iron content of the ore on Dazhu Mountain can reach more than [-]%, this quality is already very rare in private mines, and this business is sure to make a profit.

With the expansion of the guard camp, what the Four Seas Club lacks most now is a large number of weapons, and these weapons can no longer meet the daily supply of the guard camp through the purchase of these weapons from the outside. The possible high price gathers the liquid iron ore in the market.

Of course, the imperial court has very strict control over metal ores, and the amount of iron ore that can be obtained privately is limited after all. The appearance of Xia Dazhu Mountain is undoubtedly a timely rain for the Universal Society.

Even if the iron ore content in Mount Zhu is less than [-]%, in the current situation where the Four Seas Society is besieged on all sides, it is still necessary to eat up Mount Zhu, even if it is mining at a loss.

Fortunately, there is no need to worry about this problem now, with [-]% of the content, the area occupied by Dazhu Mountain is enough to supply the supply of the Four Seas Guards, and there is even a surplus profit.

"Master Zhang, you can arrange how many masonry we need to prepare here. Shunzi, fully cooperate with Master Zhang in the follow-up matters, and how much money is needed will be directly taken from the public account." The rebellious army in Yubei is about to move, and the mining of Dazhu Mountain is the current priority The most important thing is that the initial construction can even be done regardless of the cost.

Zhang Peiwu reminded: "Boss, this area is an open-pit mine. As long as there are enough people, it can be mined immediately. However, if the rock layer of the ore vein is hard, it may be necessary to use the explosive method."
