The asteroid contained one of the most important sources of dilithium ore in the Klingon Empire. To mine the precious material, a penal colony for both Klingon and alien prisoners was established there, providing sufficient labor force for the extensive exploitation of the asteroid's resources.

The surface temperature of Rura Penthe was extremely low, and the landscape was dominated by glaciers. Without proper clothing, no humanoid lifeform was able to survive for very long on the surface, so most of the mining and prison facility was located underground. A magnetic shield encased the mining facility and a vast area surrounding it in order to prevent prisoners from being beamed away. The prison complex was patrolled by armed guards. Other security measures were minimal, as they were deemed largely unnecessary due to the harsh surface climate. (Star Trek VI: The Undiscovered Country)
