I think it is made from the same material as the precursor bases, which are also in generally good shape, and made by an unkown "ultra-hard, non-reactive metal amalgam, synthesized from offworld materials. There is no indication that it can be damaged or destroyed by any means."

And since we know that the aliens that put the planet on quarantine died/left 1000 years ago, well..... hundreds of years. 1000 = 10 hundred. multiple hundred, so hundreds. :P
