Repair work will be carried out under the first phase of the two phase TSF project and is expected to take ten to 12 weeks to complete.

Completion of this phase will enable TSF to store mill tailing safely and allow the firm to restart operations of the Redstone Mill and the McWatters Mine.

Liberty Mines has contracted Leo Alarie & Sons Construction for the repair and upgrade construction work on the TSF.

Currently, site clearing and grubbing is being carried out at the site and the work on the dam is expected to start in the next week.
