At each of our facilities we have: ■ Conducted extensive studies to locate the facility away from sensitive environmental areas such as lakes, streams, wetlands and key biodiversity zones ■ Designed the extraction process so that tailings contain as few impurities as possible and are environmentally stable ■ Constructed the facilities to be able to withstand extreme weather and seismic events ■ Installed upstream and downstream monitoring facilities to measure water quality We also have comprehensive tailings management systems in place at each of our operations .
