You aren’t welcome in the mine, but the orcs won’t do anything to get you out of the mine. I found 42 ebony ore and some iron ore as well as some diamonds and other gemstones. The best location I found is Gloombound Mine which is part of an orc camp south-east of Windhelm: Gloombound Mine Location.Skyrim: Finding Ebony Ore to make Ebony Ingots You’ll probably see the Orc Stronghold first it’s attached to that. As I noted, it’s slightly southeast of Windhelm, in the mountains. Edit: realized you already mentioned Gloombound. Gloombound Mine E/SE of Windhelm is the best source.
