Daeyalt ore refinery

The daeyalt ore refinery underneath Castle Drakan.

Daeyalt ore is a rare ore created from the Stone of Jas.[1] It can only be mined by players with a Mining level of 20 during and after the Darkness of Hallowvale quest, gaining approximately 17.6 experience. It cannot be smelted into a bar. According to those working the Meiyerditch mine, the ore mined in Meiyerditch is taken to a massive underground refinery; however, the nature and purpose of this process is unknown.

During River of Blood, it is revealed that Daeyalt ore is used during the process of vampyrisation, serving as a catalyst for easing changes between states. Later, refined daeyalt is used as one of the ingredients used in making a serum to cure human-born vampyres.

Daeyalt ore is found only in the Meiyerditch mine in north-western Meiyerditch in the Sanguinesti region. A player gets 3 ores from each rock wall.

If players are sent to the mine by the Vyrewatch, they must mine 15 ores and place them in the mine cart, then ask to be released from the mine.

[FAQ] • [doc]


  • If you use the ore on a furnace it shows the message: "You're not sure what sort of effect you would get by putting this into the furnace." Trying to cast superheat item on it will display: "You're not sure what effect this would have."
  • Daeyalt ore was not stackable before the update on 20 July 2015.
  • Daeyalt was mentioned by Thurgo in a Postbag from the Hedge. The dwarf stated that the ore had "some magical hoobery-joobery on it" and that "those vampire[sic] types are after the hoobery-joobery."[2]
