*NOTE this is my first guide so if it isn't the best written guide out their I'm sorry.*
This is a guide to get 1-375 mining quick and easily. This is a smelting guide however, it will require you to mine three times in total.
This is a simple chart I put together. It will allow you to do whatever you want if you don't feel like follow me. It doesn't have all smiting in it, just what I use in my guide. Please note the ammounts I give you will change from person to person so please don't flame saying "you told me to buy 100 ore and I used 200!!! doesn't work. Smelting changes from person to person depending on luck, especially when smelting green items.
1-65 smelt copper, I suggest buying about 100 ore to start and see what happens. You will need at least 65 ore.
65-75 smelt Tin. It took me about 24 bars to hit 75.
75-115 smelt Bronze it will take about 230 smelts to hit 115. If you have a good amount of cash you may want to simply skip this and move onto Silver right away.
115-125 smelt Silver. It took about 17 ore to hit 125 for me. Or you can do 75-125 which could take around 60 ore but may vary.
125-155 smelt Iron this took me about 62 ore.
155-175 smelt Gold this took me about 25 ore.
175-230 smelt Mithril This can be rather expensive depending on your server. It took me 230 ore.
230-250 smelt Truesilver this took me 50 ore.
250-290 smelt Thorium it took me 220 ore however, you will have to mine 10 levels because you cannot smith anything else till 300.
300-315 smelt Fel Iron this took me 50 ore. Once you hit 315 go mine untill 325.
325-340 smelt Adamantite this took me 80 ore. Go mine from 340-350.
350-375 smelt Colbalt this will take around 36 ore. This is the fastest way to get to 375 although you could use Eternium and Felsteel.
350-365 (alternative) smelt Eternium this will take about 50 ore.
365-375 smelt Felsteel this takes about 34 ore.
Congratulations you are now 375 mining and no longer gain sufficient levels from smelting.
Heres what I do to to hit 450. 375-400 mine Cobalt I usually go to Zul'Drak although Howling Fjord isn't too bad.
400-450 Mine Sraonite in Icecrown or Sholazar Basin.
Congratz you're maxed mining.
