Endeavour Silver (TSX:EDR,NYSE:EXK) announced that it has received the final tailings permit for its Mexico-based Terronera silver-gold mine.

The company plans to complete a final improved prefeasibility study for the asset in the third quarter of this year.

As quoted in the press release:

The ETJ permit, or “Authorization to Change Soil Use on Forest Land”, was issued by SEMARNAT, the Mexican Ministry of Environment. It gives Endeavour Silver the right to store tailings from the proposed Terronera high grade, underground, silver-gold mine in a secure, filtered dry stack tailings facility adjacent to the proposed plant site.
Filtered dry stack tailings are considered to represent best practice in the mining sector because the tailings are filtered to recycle the water back to the plant prior to stacking them behind a storage dam. Dry stack tailings facilities cost more to build and operate than conventional wet tailings facilities but they are safer and “greener” and represent the future of tailings storage.
