Hi Robert,

Hi Patrick -

 

There was no release of effluent from the TCA in 2003.  During the period in question, the minewater was pumped into Cell 5.  This cell is bounded by a topographic high on the "environment" side, and by internal dams which isolate the water from the adjoining Ponds #1 and #2 and Cell 2.  Standard practice at Lupin over the past few years, come spring thaw, is to pump the water from Cell 5 into Cell #4, which serves as a primary polishing pond. In subsequent years, it is then allowed to flow into Pond #1, then Pond #2, before being released into the environment.

In short, that minewater won't see the environment for a number of years yet.

Hi Mike,

 

I have a question arising from a comment made by DIAND Water Resources staff.

 

During November and December 2003 approximately 4850 cu m of water was pumped from the underground workings into presumably the tailings compoundment area (TCA). 

 

Since no sampling at station 925-10 occurred, it is safe to presume that there was no discharge from the TCA due to management practices; or that everything is so thoroughly frozen so that movement of any water from the TCA is prevented (or perhaps a combination of the two).

 

Thanks,
