But he mentions doing enhancements then the BOD will decide the next steps.

Sounds like "...buy out is for sure going to happen, if , if , if, if and... if...everything changes and pigs suddenly fly"

IF enhancements are completed in a timely manner  -- yet they haven't in a decade

IF copper prices will be up it may be a "catalyst" -- yet this is to a for-ever-undefined level

IF the BOD decides on next steps -- yet the BOD has not taken steps in a decade

what about?

IF CUU management grows a pair and forces the issue, with a litigation threat if needed -- yet no sign of a pair so far
