with so many bots, i wouldn't see much point in attempting to mine unless you plan to bot aswell since you'll be there for a very long time to make decent profit.
There are many better places to mine rune. Everytime I go to wildy, I can see rune ores. Mainly due to the new dungeoneering update, people don't mine in wildy anymore. You can also join them in your dungeon if you like.
get 45 dungoneering so you can go to the mining guild place as their are 3 rocks in their that are rune also most rune miners are newbs lv 3 so they wont be able to get in so its mostly free : )
