Trahaearn mine is a mine located underneath Prifddinas. It is the only place where players can mine soft clay without the need of a bracelet of clay. However, a player will mine 2 soft clay per action while wearing a bracelet of clay. Players can find crystal shards while mining rocks in this mine.
Its entrance is found southwest of the entrance to Zalcano's prison.
This mine is one of nine in RuneScape where three iron rocks can be mined without moving, thus ideal for power levelling, with the other eight being the Mining Guild, Legends' Guild mine, Al Kharid Mine, Piscatoris mine, Lovakengj mine, Verdant Valley on Fossil Island, Mount Karuulm mine and Wilderness Resource Area.
Some of the rocks in this mine take a little while longer to re-spawn, so the conventional power levelling method for iron ore might prove a little slower. Players can, however, utilize tick manipulation techniques on 4 iron rocks within walking distance of each other to achieve the same experience rate with the added benefit of crystal shards.
Located on the southeastern wall is a mine cart which acts as a deposit box.
