Montana Resources’ Mark Thompson tells The Montanan Standard the mining pit is still frozen over. Construction on the pit has also slowed. The project to treat and discharge the water isn’t expected to begin until June.
The EPA originally set 2023 as the target date to begin pumping and treating before the water in the pit reaches a critical level.
Montana Resources wants to start early with a pilot project that was originally slated for the end of last year, but has now been delayed twice.
