Mining: A little help?Follow

Your markers will automatically change when you reach higher level areas, this prevents higher level charafters from running around in low level areas with little to no fear of death while making mounds upon mounds of money. Generally you will see an increase in higher level nodes when you change areas, I believe you will start finding Tin in areas that about level 18ish from what I remember from my first character.

I found tin around level 15, the gold markers don't change they stay the same. But yes, you can't skill up on a copper Vien at like 100 Mining(sumwhere around there) i have 107 Mining, and dont get skill ups from Copper. I have to find Tin, and Silver.
