Once again, real moons and satellites are made of rock and don’t reflect light all over creation like that. That thing is obviously metallic, obviously made of metallic strakes, and obviously artificial, some sort of a gigantic ancient space station.
Lots of things, including the terrestrial planets, have a lot of metal, including in the crust, which on Earth is mostly silicon and aluminum. IOW, uh, no. It’s an old speculation, and even Sagan suggested it (as his own idea?), but there’s literally zero evidence for it that isn’t also evidence for a prosaic, mundane origin.
My guess is that the shiny flowing looking streaks are molten glass which slopped over the sides.
