Cridwell, certainly Caladay is a promising development project but it is not the only stong card that USA is holding at the Galena complex.   If USA were to try to work the lead deposit from the Caladay shaft, which is only a narrow exploratory shaft, then yes I would agree that such a plan would require a large capital investment, potentially of the scale you suggest. However that is not the plan, the plan is to access the lead deposit from existing underground infrastructure at the Galena mine which reduces not only certain risks but also the development costs very significantly.  I think that the cost to get caladay to commercial production may be in the $30mm-$50mm range, 1/10 of the number you throw out there. I think your statement about the shafts at the galena mine being too small to support mechanization is false.  CDE mechanized the 72 stopes at Galena and the dimensions of the #3 and galena shafts did not hinder CDE from getting the proper mining equipment underground. It is very common for large equipment to be delivered to a mine site disassembled and then mechanics on site put it together.  Certainly as part of the mine plan for Caladay, USA will identify equipment of the proper scale for the job.  It is not like USA has to get a 400 ton capacity CAT 797F dump truck down the #3 shaft.   Your comment about HL producing more silver due to 'large shafts' made me laugh, thanks.  HL management has given certain folk a 'large shaft' recently, particulary the hourly workforce at Lucky Friday.  Right now HL is only producing silver because they have Greens Creek and the deposit at Greens Creek is accessed from a decline not a shaft so it appears to me that USA certainly has more shaft and a bigger shaft than HL.
