The exploration team from Darwin University soon arrived in the town of Gelton in a geological exploration vehicle.

Leonardo, an associate professor in the Department of Mining of the School of Geology, is in his Chinese New Year's Eve and wears a pair of narrow-rimmed glasses made in Italy.

"Hello, Lin. ”

Lin Han shook hands with him and smiled, "Very welcome, Professor Leonardo." ”

Leonardo nodded: "Looks like this is your land, if I'm not mistaken, this should be an abandoned farm." ”

"Can you tell me a little bit about it?"

Lin Han pointed to the green behind him and said, "This area is about forty-five hectares, as you expected, it was indeed an abandoned farm before. ”

Leonardo looked around: "With all due respect, based on my work experience, this place doesn't look very like one of those places with high-quality gold mines. ”

There are countless mineralized zones containing gold elements, but due to the limitation of mining costs, gold mines with mining value should contain at least 0.3 grams of gold per ton of ore.

The grade of a few tenths of a gram per tonne is actually a very low-quality gold mine, and few people are willing to mine it.

In terms of the domestic situation in China, the grade of gold ore is generally 2-5, and the higher ones can reach double digits, and as for the hundreds, they belong to the best gold mines.

The value of a gold mine depends not only on the reserves, but also on the grade.

Leonardo continued: "...... If there is no gold mine here, or if the gold ore grade is too low, don't you lose a lot...... You know, our exploration team is not cheap. ”

In order to invite this exploration team, Lin Han spent several times more money than buying an entire abandoned farm.

After all, in theory, knowledge is much more expensive than land.

Lin Han said with a smile: "I have a buddy surnamed Ao in Huaxia, he is a geography major, and he once happened to do a little investigation work here, and I suspect that there may be a gold mine or something here." ”

"But he didn't have enough money to buy the land and explore it, so he told me the news, and I had just bought the land from someone else. ”

Leonardo laughed: "I hope that guy who sold you the land will regret it tomorrow." ”

Lin Han laughed: "I think so too...... Where are you going to mine it from?"

Leonardo pondered for a while, then pointed with his hand: "I think it's pretty good there, let's start there, what do you think?"

Lin Han looked at it and found that the land was not within the scope of the gold mine, but it was not far away, so he nodded: "Yes." ”

......

Over the next few days, the team carried out a comprehensive geological survey of the abandoned farm, with equipment running every day, machines roaring, and team members busy.

As for Lin Han, he took advantage of this free opportunity to drive an off-road vehicle around the neighborhood, look at the scenery, and go fishing in the Dali River or something.

Because the population here is sparser than the wild animals, and the Australian government's strict measures, the condition of the river grassland forest is much better than that in China, and all kinds of animals are also very prosperous.

For example, when Lin Han was fishing, he could often catch some live fatty fish and shrimp, barbecue them on the spot, and sprinkle cumin with them, which tasted great.

The days lasted for several days, until he caught a crocodile more than a meter long in the Daly River......

Although the crocodile did not attack him, it was definitely not a good feeling to watch a vicious-looking crocodile shake its head and tail to tear the fishing line in the churning waves.

Only then did Lin Han remember that there were indeed many crocodiles in the Dali River.

There was also a news before, saying that an Australian made a bet with a friend to cross the Daley River, but unfortunately encountered a crocodile in the water and died in Huangquan.

However, the crocodile that grows in the Daly River is not a rare species, and it has been rewarded by the local government for several injuries.

Since it is not a rare species, Lin Han is not polite, and before the crocodile jumps back into the water, he grabbed the tail and lifted it directly to the shore.

The predator can fight the lion and tiger, but this crocodile is only more than a meter long, and Lin Han can easily lift it with one hand, and he is not afraid that it will struggle to escape......

......

In Australia, these exploration experts can be said to be quite dedicated, even when it is dark, they are still busy with the work at hand, and the machine is roaring.

Lin Han lit a small bonfire not far away, and on top of the bonfire was the crocodile he had caught in the Daly River during the day.

The fire was burning, the firewood made a "popping" sound from time to time, and a burst of meat aroma mixed with cumin flavor gradually floated up, and Lin Han couldn't help but swallow his saliva.

At this time, Professor Leonardo came from not far away, following the same steps, and his expression was a little excited.

"Lin, I have good news for you!"

Lin Han's eyes lit up: "How is it?

Leonardo nodded: "Suffice it to say, the shallow area just explored today has discovered more than 0.3 grams per ton of gold – in other words, the exact gold deposit with mining value has been found." ”

"We are now undertaking deep sampling and in a little bit more we will have specific gold grade data. In the next few days, we will be surveying the reserves of the gold mine...... In no more than a week, the exploration of the gold mine will be completed, and I will give you a reliable value assessment. ”

Lin Han also smiled: "It's really hard for you." ”

"This is the crocodile I caught in the Daly River today, would you like to try it?"

Leonardo was stunned: "Caught?"

"Uh...... Yes. ”

Leonardo shook his head: "Still no, we have to complete the gold grade survey as soon as possible." ”

After saying that, he returned to the exploration team and continued to get busy.

Soon, the results of the preliminary survey on the gold grade were officially released: 20 grams per tonne of gold, high-quality gold!

Higher gold grades will undoubtedly greatly reduce the difficulty and cost of mining. Therefore, the value of the same gold reserves varies greatly due to different grades.

A grade of 20 grams per tonne will undoubtedly increase the value of this gold mine!

After receiving such results, the members of the exploration team were also extremely excited, and in the next few days, they worked overtime to complete a series of subsequent surveys.

The final result was a 12-hectare mine grading 20 grams per tonne gold with a reserve of around 7.7t.

According to Professor Leonardo's comprehensive assessment, the total value of this gold mine is approximately US$180 million, or A$230 million!

The abandoned farm bought for 18,000 Australian dollars, buried underneath, is a high-quality gold mine worth 180 million US dollars, Lin Han is definitely making a lot of money!
