I only mine at about 3 in the morning, US time. And still, there's always someone, always, always someone who is too arrogant to share. Good mining locations, like Varrock east, are considered good for a reason and that's why it is mostly occupied. Try other locations and world hop. Anyways, I don't understand why people with higher levels should inconvenience themselves for a lower level, its not like they created their characters with those levels, they had to train just like you're gonna have to. I know when I was a lower level no high levels went out of there way to let me get ores, or logs or whatever. I know its not very nice but when you need something to complete a goal you don't want to unnecessarily slow yourself down.
