Coal rock

A Coal rock is a rock that contains coal. Players with a Mining level of 30 can mine coal rocks with a pickaxe, granting 50 Mining experience. Coal rocks can be found in numerous mines throughout RuneScape, most abundantly in the Mining Guild.

On rare occasions the rock may give an uncut sapphire, emerald, ruby or diamond.

Coal is used in combination with ores such as iron, mithril, adamantite and runite to smelt bars in a furnace to create armour and weapons with Smithing.
