Above is a screenshot which I took of one of the stacked ore nodes, this one contains two separate ore nodes one being Obsidium Ore, and the other Elementium Ore. However on several separate occasions I have seen up to 4 separate notes stacked on top of each other.
It usually happens when its late at night or early in the morning, and there are few, if any other players around farming ores from Deepholme.
