The chip-out doesn't quite reach the wall of the counterbore.

One might try repairing the chip with one of those aluminum weldng rods, but would need to have a fair amount of experience with that type of work and be able to make some sort of coppper dams to keep the repair material out of either bore. even then, it might need some delicate grinding with a Dremel to dress the repair.

The average DIYer might do better to look for a good used casting.

I should add that it's not unsual to find pitting damage in the casting, which requires attention/repair, but I've never seen a chip like that in a BTV before.
