At each of our tailings 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 facilities 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 at Efemçukuru, Stratoni, Olympias and Vila Nova.
