Not quite sure I follow thiese annualised revenue estimate 
of $ 138.5m Most here estimated sales revenue of around
$ 20m for the last  quarter.....So 20 x 4 = $80m annualised
sales. That's quite a difference.

Rvr are only selling zinc concentrate tonnage at around
55% zinc not pure zinc, nor pure lead etc.

One other comment for clarity, the development of Far 
West is not nearly completed and will continue 
indefinitely on incline development. Far West has
only reached the first  level of ore which still Is in the
developement drivage stage. It will be sometime
before ore stoping begins hence minimal additional
production ore from Far West.
