Previous studies of the area found sixteen preserved trunks of cypress trees from one of the oldest known fossil forests, estimated to be between seven to eight million years old. Archaeologists have been conducting ongoing excavations over the past decade to rescue any archaeological material under threat from extensive lignite mining operations in the area. The team recently discovered a cemetery containing 34 graves dating from the Copper Age around the 4th millennium BC. Within the cemetery, archaeologists excavated the tombs containing the remains of three women who were buried with various gold objects, consisting of hoops and conical plate pendants that may have been part of a ceremonial headdress. Researchers believe that the pendants symbolise the stylised female figure, with the embossment of punctured bumps to embody a feminine form. Another burial containing the remains of a high-status male was also excavated with associated grave goods, consisting of a cracked stone blade, a polished stone axe, and a copper pick.

The word copper comes from the name of the Mediterranean island Cyprus that was a primary source of the metal. Dating back more than 10, years, copper is the oldest metal used by humans. From the Pyramid of Cheops in Egypt, archeologists recovered a portion of a water plumbing system that had copper tubing in serviceable condition after more than 5, years. Copper is one of the most widely used industrial metals because it is an excellent conductor of electricity, has strong corrosion-resistance properties, and is very ductile. It is also used to produce the alloys of brass a copper-zinc alloy and bronze a copper-tin alloy , both of which are far harder and stronger than pure copper. Copper is biostatic, meaning that bacteria will not grow on its surface, and it is therefore used in air-conditioning systems, food processing surfaces, and doorknobs to prevent the spread of disease.
