RE:RE:RE:RE:Old Post Re-Hash - Due Dilligence on the PLCCement paste backfilling is becoming more of a " best practises" in Australia, Canada and a few other countries. It takes less if a footprint and is more environmentally friendly. It is more costly and requires much engineering work. There is lots of info online. Much of it goes above my head. How tailings are managed is also site specific. They have had accidents with tailings ponds recently so the environmental concerns have become a big deal. I posted some of this info previously but it was labelled as fake news. A quick search on google will show that i am correct and that poster has biases buolt into everything he posts.

Hey teevee,
If you took the time to read my "Key to the PLC" web post linked in this thread you would of seen my extensive write up detailing the development of the previous mining camps at Rabbit and McClean Lake mill sites in the Athabasca Basin that utilized in-pit tailings facilities from previously mined out shallow open pits.
I was originally of the opinion that NXE would have to utilize an above ground open pit and had pointed out that it was a direct risk. Hey! Maybe they read some of my posts and were inspired to seek alternative tailings disposal strategy? I still cannot find much info regarding this strategy. Perhaps you have come across some material?
Regardless, FCU would not have to use an above ground tailings facility in the future if they mine out and retrofit one of the multiple on land, shallow, open pits. And if you curious to know how, take the time to read the "Key to the PLC" post and make sure you watch the linked Youtube Vid to review the McClean Lake Mill Tailings Facilities Operations (Which by the way, was recently permitted to raise above the initial below ground open pit surface level, which flies in the face of your original comments of hearsay that it is unlikely that Sakskatchewan would permit above ground facilities)
View Thread, and Happy Reading.
Heres to a good week
