Save Station Mines B is a small room in the Phazon Mines. It appears in Metroid Prime. This room contains a Save Station to the left of the entrance. Fish can be seen in several tanks behind the Save Station. It serves as the first Save Station in the mines after a long, difficult trek to the Central Dynamo, as well as the only one she finds until she reaches the source of mysterious energy fluxes, which is in the Dynamo.
- The internal file names of this room, Save Station Mines A and C are "savestation_mines_a", "00_mines_savestation_c", and "00_mines_savestation_d". This implies there was going to be a fourth Save Station in the Phazon Mines at one point.
