It does have some features that make it look cast (soft details, what looks like some casting bubbles in fields), but some ancient imitations were cast. The patina looks a little off, like the effect when you use something like Jax to repatinate, but maybe it was repatinated after a harsh cleaning or the lighting is just giving that look.
It is hard to say for certain without having it in hand; and even then, it might be hard to say for certain.
