Mole mines were a type of mine utilized by the Nihil, a pirate organization, during the period known as the High Republic Era. Their method of operation involved tunneling beneath the surface, advancing towards their intended objective. Upon reaching the target area, they would breach the ground, rising to the approximate height of a person's torso before detonating. In the year 232 BBY, a number of these mole mines were deployed in an assault against Jedi including Bell Zettifar, Loden Greatstorm, and Porter Engle. This attack occurred at the Blythe homestead following the kidnapping of the residents by the aforementioned pirate group.
