1. Go in naked. I don’t mean play the game naked, but have no equipment on, and carry only your pick axe.
2. You should always mined a full load, 28 ores for each run.
3. Raise your attack level so you can wield the highest possible pick axe.
Iron 1 140gp
Steel 6 500gp
Mithril 21 1,300gp
Adamantite 31 3,200gp
Rune 41 32,000gp
5. And if you are mining lower level ores, the more busy the world is, the better it is for you. Since the more players in the world, the faster the ores will respawn. For world 1, most of the time mining copper and tin ores’ camps are empty.
