Regin is unable to make sense of the runes in the mining records you found. Strangely enough, they appear to be written in an Elvish script.
'I can't ken these runes at all! Why, unless I miss my mark entirely, I think these are some kind of Elf-writing.
'Now, how could directions to a dwarf-mine have ever been written in some Elvish script? Do you think anyone in these parts could understand this language?'
Dwarves can be found all over Othrikar.
Surely one of them can translate the Elvish mining records.
Regin is at Othrikar in the North Downs.
The old records have been translated, but apparently a map is required before the directions will make sense. You should return to Regin with the deciphered records.
