The dwarf mines were converted into the Dark Dungeon to hold Rumple. It only took a few hours at the most to reach Lake Nostos from the Dark Dungeon in 2x09, and the lake is located in Maidas' kingdom as said by Abigail. So, the Dark Dungeon is within Midas' kingdom. The fact that Snow asked the dwarfs to build the dungeon has nothing to do with where it's located.
