Help me with miningFollow

Silver is a rare spawn of tin - keep mining all the tin sites you can find, and some of them will respawn as silver. I believe at 120 you should be able to mine iron - that will level you up as well.

I'm not sure where to find ores on the horde side, but if you type the name into the search box on the left, it will show you maps of all the sites where it has been found by region. Just pick a region you're familiar with or that is within your level to move around in, and go to it.
