Well you did say free, so I would have to say RiD's Powerminer (link in my sig)
Powermines in all the best locations (doesn't do Rimmington however)
I have gone from 50-85, 1-85, and 1-50 on 3 different accounts and no ban.
note: Not even a single user has ever been banned using RiD's Powerminer. So that's a plus![]()
Mining iron in varrock mines?
