Seems like a good guess, but really need more information. Like, a single 'clunk', more than one, or a periodic knocking like engine knock or loose suspension arm etc...

I would rev the engine in neutral, with hood open, so someone else can watch how much it moves. The mount would have to be completely broken to bounce more than once and make a noise like metal on metal. If the engine is bouncing around like that, it will be easy to find by inspection from under the car or on the lift.
