No it isn't.

The BFS is a snapshot of the economics of a given set of mineral deposits and an estimate of the costs associated with developing and mining that set of minerals.

We know that the BFS due this month will not accurately reflect the mineral set that actually exists.

Everybody known this, including TECK.

What the required POSITIVE BFS does is validate that there is sufficient mineral and mining capability in this area, based on results at the time of the BFS, to warrant a go-ahead, based on the sheer economics of the data as evaluated by a recognized authority in the field.

It is related to value, but is a snapshot of the data at a recognized point in time.

No one is naive enough to think the valuation process stops at th BFS cutoff.

The price will continue to evolve, hopefully up.
