I was looking at my toons profession tab and seen that I haven't learned this recipe yet for mining. It takes a skill level of 600 and is learned from a book. Couldn't get any other info out of it and I was wondering if this was in the beta, or just something that wasn't (and probably won't be) implemented?
Their are a number of enchanting and blacksmithing patterns that exist according to blizzard but never got added to the game. I would assume the same.
