This is the issue. It's not that everyone needs a mine, it's not that most people should be able to trade away metal, it's that there's basically two sorts of people, those with metal and those without. A metal plow is so very much faster than a wooden one at the moment, once you've used metal it's hard to use wood without cringing a little. Same with metal cauldrons (no wait? yes please!), same with shovels and scythes (both only available with metal), same with cellars, extra keys, keyrings etc (why I can't use a strip of leather as a keyring is beyond me).
Rather than just keep adding mines, I'd alter the metal gathering process or bring other options in, like BWithey has mentioned.
A change I'd like to see would be small amounts of metal findable by methods other than owning a buttload of metal in a mine. Instead of rustroot+prospecting only finding a motherload or nothing at all, maybe each use of rustroot has a chance of giving a random type of nugget or ore as well as point out where mines are. That way you can introduce small amounts of metals (enough for hermits/isolated people to get the quality of life metal tools and be able to maintain them, with a bunch of work), doesn't have to be enough to equip every villager with . Perhaps it could be quality limited or some other thing to keep mines as valuable as they are, while still offering some options for do-it-yourselfers.
I've spent the last two days searching for mines, including every cave I find, random wilderness spawning and travelling the outer supergrids, still nothing. Half the mines I come across are in dead/virtually dead villages and claims, all undetectable by prospecting. I don't think mine decay or more mines would fix the issue, since you'd still just get people claiming them for the sake of controlling them. Sure you can trade for them, if you can get somewhere without getting killed/lost/completely-bored-of-travelling-supergrids-until-you-find-someone-who's-active-enough-to-trade.
TL;DR: Do not need more mines. Need more alternatives to metal or the ablilty to scrape together small amounts for the quality of life tools.
