Cost/benefits analysis of restocking a gold mine
Does anyone know of a way to calculate whether buying gold ore in the Trade Office is worth it? For example, I’ve built a gold mine that will eventually be exhausted unless I purchase (or am awarded) more gold ore to deposit there. But at some point, it’s not worth paying the price that a seller is offering because once it’s mined, smelted and turned into coins, the coins that are produced will be less than what I paid for it originally. Is there a way to determine the price point at which buying ore doesn’t make sense? How much ore produces each gold coin?
Obviously, you have figure in the cost of constructing a new mine once one becomes depleted vs. buying more ore to refill an active mine. There’s also the issue of buffing, which if done consistently, will allow me to extract more ore than is actually there.
Am I missing something?
