Handsome miner. L3 brow was 2800 yds from top to bottom. And don't forget they had a little face off to the left, L17. That went about 200 yds and was about 50 yds long trying to prove the ground towards suspected large faulting. I think it just closed up on them. I never went on there, it was just before I started in the pits.
L19 retreated back about 1150 yds so when it finished it would have been about 1750 yards from L1 Level.
