Mining in wild is out of the question, red spiders can attack you out there. I also think the other alternatives require somewhat of a combat level. Your best bet is to do lower level ore. Also rune ores aren't that great, you often have to concentrate and plan a lot of what you are doing. This includes timing ore, banking, figuring out the best ways to run back and forth, logging in with revs on you and various other stuff. (Also to answer your question I have seen low level revs out there that will att you.)
There is many equal ways of getting gp at the same rate that don't require as much work. good luck bro.
