A friend told me that he had played on a server that had a plugin or something that maintained a separate world he could teleport into, which was rich in minerals.
Every so often, that world was dropped, and thus recreated, and was ever-fresh every day with new minerals.
Does anyone know the name of that plugin, or how to set up this system?
We have bukkit on our server, but not much else other than "bukkit essentials".

That sounds a lot like the Mystcraft mod. It's not a Bukkit mod though; it's a Forge mod.
PS: I should warn you that moving your world from a Bukkit server to a Mojang server (which Forge runs on) can affect your world (not necessarily, but it's known to happen). I'd recommend you looking into Feed The Beast and their modpacks, all based on Forge, and some of them including Mystcraft (and lots more).
Good luck.
