This may have been posted on this forum before, but it's my first time seeing it...very detailed and simply organized. 

Once TDC takes off, many of the past producing mines and associated claims may be snapped up for small players, like VGC has done, and will be players queing on the success of TDC.

May be worth your while to take a read and point out any key facts you find.

I'm finding interest in the history and future of the blue-fish hydro plant, as well as bond/cleam-up obligations. 

Starting at page 6, Miramar Con Mine, there are details of past production and that the resources is "exhausted".  This had been a question for me, would the Con Mine ever re-open? Evidently not.

What can be learned about the remediation of the site, to be factored into the environmental management of the future TDC mine?

Giant Mine (Starting at page 9).  Again, environmental clean-up is an important issue, as the bankruptcy of the owners left a mess for DIAND to clean up.  They are probably very concerned about not having such a mess again in the future.  ALso interesting, the extension of the life of this mine was along the theme of seeking additional reserves to make use of the same infrastructure.  This has been reflected in Dr. Webb's interview from 2006, where he talked about the efficiencies of expanding the resource within range of the infrastructure for the TDC mine.  This helps me now to understand why they have to jump around a bit, to confirm that there is potential in the 4 or 5 exploration areas, with a long-term view of how to make long life use of the infrastructure.

 With those two mines exhausted, perhaps the thing of value they continue to produce are lessons learned (by Dr. Webb) to be applied in mine design, but also lessons learned by DIAND and NWT / regulatory and community concerns which TDC is right to place a large emphasis on in their mine design.
