Try fsck after this step, before you mount it:

fsck /dev/md0c.eli

mdconfig -a -t vnode -f /home/staff/mikej/image md0
geli attach -k /etc/gli/image.key /dev/md0c
mount /dev/md0c.eli /private
(root at firewall) /home/staff/mikej/bin# mdconfig -a -t vnode -f
/home/staff/mikej/image md0
(root at firewall) /home/staff/mikej/bin# geli attach -k /etc/gli/image.key
Enter passphrase:
(root at firewall) /home/staff/mikej/bin# fsck /dev/md0c.eli

fsck: Could not determine filesystem type

(root at firewall) /home/staff/mikej/bin#
