Yes.  You should take a look in /var/backups, you may find a backup of
the partition table from the failed drive.  Assuming you remove the
failed drive first, you can safely `gpart restore -l` this backup onto
the replacement drive, which will recreate the labels (but not UUIDs).

You can try to use recoverdisk to copy undamaged portions of the failed
drive onto the replacement, but it's likely to take longer than
resilvering.
