Well, I think you need to read the overall situation.....
I doubt Copper Fox decides to stay for Teck's PFS report as that could take 1-2years longer of waiting. The company clearly knows many investors are not happy about us waiting further for 2021 results.....so would they dare stay past that event? It would do more harm than good to the company's reputation and share price.
Clearly the directors of CUU feel a substantial amount of more value can be obtained waiting a few more months before declaring a sale process or completion deal. The idea of better recoveries, higher long-term metal pricing and reduced costs positively changes the npv in our favour greatly! Remember this current pea report factors changes from end of 2020, we nearing 2022!
Other things to consider before sale process:
1) Teck coal deal (Rumour is 8 billion tag. This means more money in the Teck treasury to develop their other copper assets? Or buyout out their Minority partner)
2) Copper Fox wanting Teck to announce a PFS report on SC (Higher level of development means more money in the industry- other majors will take notice)
3) Higher long term metal prices as copper stays above $4 American
4) Further into bull metal cycle (Other Majors have more in their treasury for M&A and reserve replacement)
5) Better recoveries & Reduced costs = higher NPV (Hence why the 2021 drilling data needed)
