I'm 99.9% sure it's made of aluminium...

I would recommend TIG welding it, but I dunno how feasible it is in-situ without dropping the sump...

The sump would have to be removed as it won't weld when full of oil.
I've welded a few aluminium sumps at work, if its cast it will depend on what else is in the alloy, some contain magnesium and other crap which won't weld. If its a good quality aluminium then it should TIG weld ok, just make sure its pre heated and allowed to cool very slowly.
