The geology around the town of Norseman is actually very good, with a large amount of metallic minerals in the rock formations in this area, which geologists have also named the Kambalda-Norsman Gold Mine. The area is famous for its abundance of gold, not only in the vicinity of the town of Northman, but also in the famous Kalgoorlie.

The 'Golden Mile' in Kalgoorlie's super gold mine refers to the fact that more than 1,300 tons of gold have been mined in that gold mine of about a square mile or so in more than 100 years!

Located in the southwestern part of the famous Norseman-Veluna Belt, the Kabardino-Norsman Goldfields are dominated by komatiite and magnesiatic to labial basalts, which are interbedded with beds of homologous magma, graphite or sulphide-bearing shales, mafic and ultramafic formations, overlain rhyolite volcanic rocks and semi-epigenetic feldspar-bearing sedimentary rocks.

In the process of crustal change, the rock layer with this characteristic is very easy to form mineralized gold deposits due to the participation of small intrusions, which is why this area has become one of the world's most famous gold mining areas.

Of course, in addition to the extremely valuable gold mines, like other minerals, this area is also very high. Just like the land bought by the fat mine owner, in addition to an open-pit gold mine that has been exhausted, there is also a hematite with a reserve of not very large, but the grade is as high as 56.

According to common sense, it is not easy to find two metal deposits in such a land of about ten square kilometers, and the gold mine has long been exhausted, this hematite has been mined for five years, and many places have mined pyrite with high sulfur content, so for this survey, the very experienced Tang Feng has no hope.

In general, other associated minerals, such as pyrite that has already been mined from this deposit, are found on the margins of high-grade hematite deposits. In the event of a decline in grade and other associated ores, the deposit has been largely exhausted. Just like the iron ore mine of the fat man, pyrite has appeared at the end of the three tunnels, so the death sentence of this deposit has basically been pronounced.

Of course, those pyrite is not impossible to mine, but the sulfur content of pyrite is far more than hematite, and the cost of refining is much more than hematite, so unless the grade of pyrite is very high or the miner insists on mining regardless of the cost, the general mine owner will not tinker with those pyrite.

In the past half a month, Tang Feng and the others have gone down the mine three times, carefully analyzing the mined pyrite, and today is the fourth and last time to go down the mine. If there is no major change in the data obtained from this underground survey, then the leader can tell the fat mine owner that this mine no longer makes sense to be mined.

As for other mineral deposits, although there are also under this land, none of them have formed deposits, and there is no mining value at all. At this point, in the past half a month, Tang Feng's colleagues have come to a conclusion.

In other words, the good luck of the fat mine owner has run out, and this land of about ten square kilometers can find a next home! It is estimated that it can also sell for three or four hundred thousand Australian dollars!

Because today is the last time to go down the mine, and it is also an underground survey to draw the final conclusion, both the head and the fat mine owner came to the mine early, waiting for Tang Feng and them to get the final data.

"Hey, Arnold, do you think there's any minerals in the ground that can be mined?" Fat Mine Owner York. The expression on Edmonds' face was not very good, he had seen the survey results for this period of time, and the situation was not very good, but as the owner of this land, the fat mine owner still had a little hope in his heart.

Although he spent more than a million Australian dollars to buy this land and made a fortune relying on that hematite track, who doesn't want to have more deposits in his land? In these days, as long as there are mineral deposits suitable for mining, it means a lot of money! No one likes to get along with money.

The leader shook his head with a wry smile and said, "Man, although I would love to find a suitable deposit again, I think it's almost impossible. There are a lot of metals underneath this land, but as far as the data is concerned, they do not form high-grade deposits and cannot be mined. ”

It seemed that he felt that this was a bit heavy, and the head patted the fat mine owner on the shoulder, and said with a smile: "Man, that hematite has also made you a lot of money, if it really doesn't work, this land can change hands, and I will find you a good place again, you can buy it, and you can still be your comfortable mine owner!" ”

The fat mine owner squeezed out a smile, did not squeak, but looked at the more than ten people who were about to go down the mine in the distance.

Suddenly, there was a commotion in the distance, and the head and the fat mine owner frowned in unison, and walked down from the top of the hill together.

"Hey, boss, if this ventilation equipment is not activated, it is dangerous to go down the well!" Seeing the boss and the fat mine owner coming over together, Sam, who is the legal adviser, said to the boss with a very solemn expression.

"What's going on?" The leader was also a little puzzled, and asked with a frown.

"Boss, when we went down the mine the day before yesterday, these ventilation equipment were still working, but today these ventilation equipment are not working, it seems that there is a problem with the electricity. Boss, you know, if the ventilation is not running, going down the well is not fun! Clarke, the demoman on the side, said.

The head didn't speak, but turned his head to look at the fat mine owner, who showed a trace of embarrassment on his face, hesitated and said: "This morning, the notice from the street town that there is something wrong with the high-voltage transmission line leading to the town, so it needs to be blacked out for maintenance during the day today, and even the ventilation equipment in the mining area cannot be operated." ”

Tang Feng interjected and asked, "You should still have a spare oil engine here, right?" Could it be that the diesel generator can't be used either? ”

The fat mine owner pursed his lips in embarrassment and said: "The oil engine is ready to use, but you know, my mine has been stopped for more than a month, so I took this opportunity to pull the two oil engines to the town for maintenance, and it is estimated that the maintenance has not been completed yet." Arnold, you see"

The leader thought for a moment and asked Tim, "Tim, if there is no ventilation today, is there a problem going down the well?" ”

Tim. Stanton is the number two person in Explorer, and is responsible for specific surveys.

Hearing the boss ask, Tim thought for a while and said, "We just went down the shaft the day before yesterday, and the situation in the underground is not bad, after all, this is just an iron mine that is not very deep, I don't think it should be a big problem." ”

Compared with coal mines, the safety factor of iron ore is much higher, generally common in coal mines gas, carbon monoxide and other dangerous gases, although there are also exists in iron mines, but it is definitely not as serious as coal mines, and this iron mine has not been produced for more than a month, according to common sense, it should not produce any dangerous gases, not to mention that they have just gone down the mine a day in advance.

The fat mine owner on the side also said: "Arnold, there should be no danger, I am familiar with this place, there has been no accident caused by dangerous gases in this mine over the years!" Although the ventilation equipment won't be turned on today, I can guarantee that there will be no accidents! ”

The leader nodded and said, "Take your respective equipment, bring a small oxygen cylinder, and bring a dangerous gas detector, be careful!" ”
