The Superheat Item spell allows faster mining of coal due to the reduced need for banking. Repeatedly mining four coal, casting Superheat Item on Mithril ore, and banking when needed yields decent profit and experience in Mining, as well as some Smithing and Magic experience.

At level 60 Mining, it's possible to produce about 88 mithril bars per hour with this method at the Mining Guild. Other places to mine coal include the West Lumbridge Swamp mine (where the Falador Teleport and Lumbridge Teleport spells can be used for fast banking and return), Barbarian Village mine (if the player uses the imbued skull sceptre for fast access), and the Dwarven Mine. Players not afraid of danger may also want to consider the South-west Wilderness mine.

After filling an inventory, they can also be taken to the anvil in the north-eastern part of the mine to smith mithril platebodies, so they can be converted into coins with High Level Alchemy. This allows for almost infinitely long trips only dependent on the number of nature runes. This method will take longer than banking the bars, and will net 1,510 per 5 mithril ores made into bars. This is profits −1,675 coins compared to just selling the 5 bars made.
