Good question, here's the information released by Teck today for Schaft Creek in the AIF:

The results of the 2020 scoping study inform work planned for 2021, including drilling, geotechnical field investigations, baseline environmental studies and updated capital and operating cost estimates.

Planned spending in 2021 of $ 3.4 million on Schaft Creek, which will be included in growth capital expenditures within our copper business unit.

While Teck won't commit yet to a development program it does appear they are prepared to accomodate CUU in their efforts to sell by showing some level of activity.
