RE:RE:Is FCU's R780 east mineable?thanks for that link. After reading that, I wouldn't buy FCU with your money. Here is my takeaway from the article:
The key issue with simply tossing rocks in a lake to make a dam is the fact that the water will flow under the dam through the sediments and this water will then require treatment since it is now in the pit. Water treatment was the nail in the coffin of Areva’s Midwest Lake pit proposal based upon those I talked to.
So I suspect the dams at Paterson Lake will need to include a frozen core achieved through drilling vertical holes through the core of the dam into the basement rock and using a freeze plant and thermosiphons to create an impermeable core. The rock core is replaced by slurry wall prior to drilling and freezing. Doable but likely $200-$300M required before all is said and done.
