""Just talked with one of the mine supervisors.... he confirmed:

- they are about 550 feet from the hinge zone ore now, and the shaft is progressing about 20 feet per day. Once they get there, then the development work will begin. Then, at least, they will be extracting devlopment ore in the process rather than waste rock.""

North Lion,, I thought they were driving decline, not sinking shaft. If indeed they are driving decline It would seem that they should be doing more than 20 feet per day.

It has been a while since I have worked underground, 1958 to be excact, when we drove a 20 by20 tunnel through mission mountain at Shalath BC. We always pulled 2 12 foot
rounds a shift except when we had to lay track. So we averaged about 60 feet per 24 hour period.

I thought mining methods and equipment had improved in the last 50 years.
