Gold in upper manifold 2001 s10?

I took off my throttle body and noticed a lot of gold colored build up in my 2001 4.3 vortec. I saw a post that this is a sign of a fuel leak. Can anyone confirm this? If yes would it be most likely the injectors?

These engines often have issues with the fuel injection “spider”.
