My take on all this is that everyone was prepared to proceed on the promised BFS and Tetra Tech muffed it, and have acknowledged that

So when you are given lemons, you make lemonade

It was always a given that the CUU negotiating position would be enhanced if all of the completed drilling results could have been folded into the BFS

Everybody took the pain of the slippage, but some of us are looking forward to the fact of a revised RE, with substantial improvements in all areas of the resource definition, now being folded into the discussions

I don't think anyone is prepared for any more slippage in getting this transaction under way

Neither Teck nor Copper Fox have any desire for more delay, IMO
