Are those screws exposed on the outside?
Also, if the bolt has an angle facing outward and there is no anti-shim protection you might be able to shim it.
I was unable to find your exact lock but most of the similar modern mortise style locks with lever mechanisms have pretty secure bolt designs and if yours requires the key to actually be in the lock before the bolt can be withdrawn or the handle turned then you are probably screwed. Only a locksmith adept at picking lever locks (and not all are), can help. Better pictures of the bolt. (on another door of course) might help.
