How much is mine at least?

It depends on the source of the mine. If it is an "open pit mine", the investment is relatively small. The main inputs are workers' wages and transportation road construction costs. The ore is deeply buried and needs investment. In addition, the acquisition of mining license is also part of the investment, and this is the main part. Without a mining license, everything else is empty.

To sum up, the investment expenses are mainly as follows

1, workers' wages

2. Mechanical equipment

3, transportation road construction and maintenance fees

4, for mining license fees

5. Other expenses.
