The mines are located in Sector 2 of the facility. The location is found after the protagonist successfully survives his first encounter with a long-haired creature; he must then leave his submersible on the shoreline before the entrance to the mines.
The mines are all connected to a vast chamber with mining equipment, worker albinos, and seismometers. An elevator may be used to reach other levels of the initial complex. A large sealed door separates the first area of the mines from the pulse; a pressure plate with the weight of 20 individuals must be activated in order to open the door.
- The lever-activated shields used for protection against the pulse can be seen again in Sector 4 of the facility; however, their purpose is unknown as there does not appear to be anything equivalent to the pulse in that area.
