Capítulo 690: Chapter 309: Increasing Revenue and Reducing Expenditure_3

Moreover, the barbarians' mining technology is backward. If we use the more advanced mining technology of our Great Chu, the production of these eleven gold, silver, and copper mines can at least double and reach an annual output of 4 million silver taels.

Aside from this, there should be other undiscovered mineral resources in Qianzhong County. If we carefully search for them, there should be many gains.

As long as we discover one, it would be enough to annually increase the income of our Great Chu by hundreds of thousands of silver taels.

In my estimation, if we could reform the existing mining technology and simultaneously develop new veins, then before these mines are depleted, Great Chu can have an annual increase of 5 million silver taels.

If more mines are discovered later, this annual income would be even higher, reaching 10 million silver taels is not impossible.
