Some of you may or may not remember me, but I haven't played this game for around a year, a year and a half. I'm F2P (big surprise right?). Anyway, I'm slightly interested in getting my mining up a bit. I know rune pick is the best but I'm assuming that powermining iron is still the best? If so, where is the best place for this at? Thanks in advance!

Depends. Best place for xp is the three iron rocks in the dwarven mines, and you can bank the iron in the resource dungeon right next to it in less time then it takes to drop. Might be hard to find a world with no other people / bots using the rocks, though. Next best would be 4 iron rocks at rimmington mine, but you would have to drop, or lose about a minute when banking (daemonheim tele + clan vexilium tele). Make sure you use urns no matter what, raise xp/hr by like 5K :)

Where would I go about getting these urns (I've seen several people mention them)?

G.e.

 

You have to activate the urn. I believe mining is an earth rune. Just use the highest level urn you can.

You can buy them from the grand exchange (overpriced), and then you add an earth rune onto it to activate it. Or, you can make them, only takes a few minutes and I usually find a it's a good distraction from whatever skill I am doing. The best place would be in the crafting guild, everything you need to make them from scratch is there. You will still need to put an earth rune on them when you are done, though.

just buy them.. please.
