The Farmine Mines are only accessible after completing a certain mission of The New Frontier Quest. It can be reached by entering a teleporter in Farmine, here. It is one of the larger Stone Golem spawns, and therefore a good place to do the Stone Golem Mission of the Killing in the Name of... Quest.
The first level down has Gargoyles and Stone Golems close to the teleport and Gozzlers at the ends of each tunnel.
The second floor down has all three creatures near the entrance and throughout each tunnel.
