- Area: 20,380 m²
- Product: COLETANCHE ES3
The Dolores Mine is a large gold and silver mine located in northern Chihuahua, Mexico. The Dolores Mine is one of the largest silver reserves in Mexico and in the world. This expansion had a number of constraints that made COLETANCHE the best solution. COLETANCHE was placed on the new leachate backfill liner.
COLETANCHE geomembrane’s advantages for this project are:
- High friction angle (34 degrees)
- Puncture resistance
- Protection of cash reserves
- Quick installation
- Installation possible in extreme weather conditions (precipitation, wind, hot temperature of 35°C/95°F).
