Argonite ore

Argonite ore (Tier 7) is an ore that can only be obtained while Dungeoneering. It can either be bought from the Smuggler, received as a monster drop or mined from an Argonite rock. Argonite is the equivalent to dragon. It requires level 60 Mining.

A player may receive between 1 and 5 ores from each argonite rock, after which it is depleted and no further ore can be mined.

Smithing
A player can smelt argonite ore into an argonite bar through the Smithing skill by using it on a furnace; this requires level 60 Smithing. Argonite bars can then be used on anvils with a hammer to create Argonite equipment.
