And, yes, I forgot to take into account that the Deeper Mine has a better success rate. That changes things considerably. If I my arithmetic right, that means there is a (0.9)^5 = 59% chance that the Meal will be spent without producing a (e.g.) Coal. So, each Coal will require 1/0.41 = 2.44 Meals on average. That isn't nearly as dire as what I had imagined, and a Deeper Mine is definitely better than a Mine when depleted, but the point is well taken: A depleted mine is still way more expensive than a well-resourced one.

I frorgot to mention that the numbewr of attempts differ between different mine types as well. E.g. a coal mine has more attempts as a ironmine. I just wanted to make the point that you can't make any assumptions about costs from the information how fast at max a site can produce, if fully stocked. Edit: regarding your arithmetic. the attempts are not dependent on each other, so I believe it you need 10 attempts on average to get a coal resulting in 2 meals per coal on average.

I guess I haven't paid enough attention, but I just spent a while watching mines and I see you are right. All this time, I thought one coal, etc., required one ration, etc. Thanks for clearing it up for me.

This is interesting. Where do we get these numbers?

Where do we get these numbers? currently only fromm the lua files of the mines. However you might guess the number from the number of minerals produced shown in the in-game encyclopedia. Top Quote
