After weighing taxation against growth, the campaign turns to gold and silver mines as sources of revenue. Gold is treated as a fungible asset that can finance other parts of the state rather than a resource useful only where it is extracted. The same region also produces trade income and contains an important university, so its defence protects both current revenue and future development. The game compresses the speed at which mines become spendable funds, but productive assets enlarge military capacity only when the state can hold them.

Gold mines as a fiscal base worth defending
Fungible mineral wealth finances the wider state, making mines, trade income, and a university valuable enough to justify a stronger garrison.
