Runescape gold guide, the first.
Put on your golden helmet and talk to Dondakan. He'll fire you into the mine. Mine 27-28 gold ore. Unequip your helmet or disconnect and log back in to leave (Disconnecting allows you to keep your helmet on and mine 28 gold ore, but may be slower).
Head east across the footbridge to a dwarf standing by a boat (called "Dwarven Boatman" in game, though I call him the "Banking Dwarf" in this guide). Hand over your gold ore, which he'll bank for you. Repeat 1-5 until you have all the gold you want.
This dwarf takes one ore off the top and one more for every 5 gold ore you give him (rounded down).
The maximum number of ore you can mine per trip is 28, although it is recommended that you only mine 27. If you mine 28 ores, you must leave the area by logging out and back in, which can be time consuming, but if you leave one empty slot, you can simply unequip your helmet when you want to leave.
Some players recommend you bring a chisel and glory ammy. You can cut and drop gems you mine for a little extra crafting experience and get a little runescape gold, but it costs you an inventory space.
