‚ÄčThe cold climate at our Raglan Mine site, with an average temperature of -10 degrees Celsius, allows for our mine tailings to be stored in a process that freezes and stabilizes the tailings in permafrost, preventing acid-mine drainage. However, any increase in the ambient temperature due to climate change requires us to identify ways to ensure that our tailings remain frozen. Currently, we are using third-party expertise to provide recommendations for potential long-term solutions to confirm our tailings management process. This is a key topic of discussion with the Raglan Steering Committee.

It is important to note that our current concept is effective and will be for many years. However, since the original concept for tailings storage was developed before the effects of accelerated climate change were known, some adjustments are required to ensure our tailings process remains fully effective over time.
