coolant leak from cast block mounting?

Hi.
My coolant leak seems to be coming form the casting that is mounted on the engine.
The one that then takes the PS pump and the coolant pump.
Has anyone else seen/had this and do you know which gasket(s) I need to reseal it?
Thanks in advance.

The seals in your coolant pump have failed. New pump and gaskets

As I am going to have to take it off anyway I was going to change it, but there is a circular seal in the mount, I have just discovered part ERR6711 (Thanks @PopPops ) that could also be the issue, so I'll be changing that too.
Have you seen many of these go and do they usually leak the same way?
Cheers!
