Daeyalt ore

Daeyalt ore is a rare ore that 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. Currently, it cannot be smelted into a bar using the Smithing skill. 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. According to Jagex, this ore was created by the presence of the Stone of Jas, when it was currently being hidden in the Meiyerditch mine.

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.

Speculation
The similarity between the spelling of Daeyalt and the pronunciation of 'day out' and the anagram 'late day' has led to speculation that this ore may prove to be dangerous or beneficial to vampyres. This speculation was fueled by Master Smith Thurgo's reply in the Postbag from the Hedge (issue twenty-two) claiming that the ore had "some magical hoobery-joobery on it" and that "those vampire types are after the hoobery-joobery". During Branches of Darkmeyer, it is learned that Daeyalt ore may be used in haemalchemy which may be a word meld of the Greek root haemo- meaning "pertaining to blood", and alchemy. It is not the only use of it though, as Lord Drakan obsesses over it after trying to cover up this use.

Future Purpose
According to the Live Q&A- Lore, Jagex is planning to make a spin off quest from the Myreque quest series dealing with Daeyalt ore, but will not have to do with the main series itself, instead hinting at the ore's formation from exposure to the Stone of Jas, just as its lingering energies created the Fist of Guthix and permeates the Glacor Cave.
