The Praxis class advanced mining station is a much more efficient resource gathering Klingon station which has an efficiency of 100%.
History and specifications[]
The increased mining rate is done so through the use of specialist mining equipment. Its larger size requires a more powerful, and efficiency, power generator which in turns enhances the structural integrity and deflector system. This allows this advanced mining station to survive attacks that would destroy its predecessor within the Klingon Empire. (ST video game: New Worlds)
