The CEO Message on the Copper Fox website states that:

"Since 2013, Teck Resources Limited; the operator of the Schaft Creek Joint Venture has funded approximately $20 million on field programs, desktop studies, reviewed the major components of the 2013 Schaft Creek Feasibility Study and collected additional technical information from the project.

Over the past year, the project has been included in Teck's Project Satellite initiative and the status of the 2013 Feasibility Study demonstrate the advanced nature of the project. The 2018 Schaft Creek work program has the objective of evaluating a number of scenarios to identify value enhancing opportunities for the Schaft Creek project. This work needs to be completed in order to determine the next steps for the Schaft Creek project"

Therefore, Teck has spent $20+ million of its own cash (Teck funds 100% of development costs) on Schaft Creek since 2013 and, as a result, has now included Schaft Creek in its Project Satellite Initiative.

Would appear that Teck is taking the Schaft Creek opportunity pretty seriously!

In which case, forecasts of declining supply and increasing price of copper should, logically, accelerate the timing of mine development. Do not forget that a positive decision generates a payment of $20 million from Teck to Copper Fox.

As regards timing "work needs to be completed in order to determine the next steps for the Schaft Creek project" i.e. nothing to tell us until there is something to tell.
