I think that "pounds per copper" is something that only works when working backwards, not looking forwards. It's the economics of the pounds that matter more than the pounds itself.

Having 10 billion pounds of copper for "free" or "getting paid to mine copper" when extracting is a lot more valuable than 100billion pounds that costs $3 a pound to extract (as an extreme example).

You are right though that until the BFS is released, we really don't know the economics of the project and guessing what we might be bought out for is difficult since our PFS really is rather old and the story has changed quite a bit since then as well as the industry and markets at large.

The only thing we do know is that, unless something extrodinary happens, we're worth more than we're currently being valued at.
