It doesn't make sense that they would delay the Feasibility until January and then set about preparing a new RE when they can wait a mere two to three months and have an updated RE2 incorporated into the BFS.
Prospekt, doing the RE before the Feasibility would put us out in June....
To do the RE they must wait for all pending Paramount Assays...then it would take 2 months to complete the RE, then another 30-60 days to incorporate the info in the Feasibility. And at that point the 120 days start....
Now they decided to complete the Feasibility = start the Teck clock asap.
And while they wait for Teck they complete the Resource Estimate.
When it's time for Teck to elect thay have in 1 hand a BFS to prove it's economic and in the other hand a superior Resource Estimate to prove the value.
All this including the Teck 120 days should be over by April....
