I've come into this from the ATC forum at Bally's invitation.
Without looking at the plates and AIP one thought immediately comes to mind. If the min safe alt for the area is 1400ft, does the mention of 1400ft on the go-around suggest that you should climb at best rate to this level (at which point you'll be terrain safe) and then at a lower rate - if you wish - to the hold/fix?
On the question of separation... Sorry but no instrument approach procedure provides separation - this is achieved by issuing the appropriate clearances. In an ideal world no controller will put another aircraft in the hold at the missed approach level (or if it's absolutely unavoidable, he/she will issue alternative missed approach instructions). Unfortunately I accept we don't live in an ideal world and some airport systems kind of force you into doing so.
