Developing the TM-REX with our partner TransAlta

In April 2023, Montem Resources sold 50% of the TM-REX to TransAlta Corporation. Montem and TransAlta have formed a partnership called the Tent Mountain Pumped Hydro Limited Partnership to jointly manage the project, with TransAlta acting as the Project Developer.

As a result, Montem is permanently closing the Tent Mountain Mine and has terminated the IAAC Impact Assessment and AER Environmental Impact Assessment for the Tent Mountain Mine Redevelopment Project.
