Asset Retirement Obligations

 

As at December 31, 2024, the estimated cost of closure is $3,323. The Company maintains a surety bond for $3,450 as financial assurance based on the October 2021 closure plan.

 

The full estimated closure cost in the new closure plan incorporated a number of new disturbances that have yet to take place, such as new roadways, new chemicals on site, and a new tailings area. The new closure plan also included cost updates relating to remediating disturbances that existed at December 31, 2024. The following assumptions were used to calculate the asset retirement obligation:

 

 

Discounted cash flows of $2,842 ( December 31, 2023 - $3,126)

 

Closure activities date of 2073 ( December 31, 2023 – 2037)

 

Risk-free discount rate of 3.33% ( December 31, 2023 – 3.98%)

 

Long-term inflation rate of 3.0% ( December 31, 2023 – 3.0%)
