The Saturnite alloy research facility is a location in the southwest of the Big MT in the Fallout: New Vegas add-on Old World Blues. It is located southeast of the Z-43 innovative toxins plant, and is a factory based on top of a cave system where there is an exposed lava flow. As Saturnite is shown in-game to retain heat to the point where a blade forged from it can be used to melt away metal, the use of lava for testing this property makes sense. The building is full of crazed Mister Handy robots, along with one unique Mister Handy by the name of Sparks.
