Historically, this area also saw intensive mining during ancient times, as proven by the large accumulations of rust found in the region.
Located about 3 kilometres west of the Asgata village. The large accumulations of rust in the region prove the intense mining activity that occurred during ancient times. The deposit had a volume of about 250.000 tones and its content in copper was 1% and 30% in sulphur. The modern mining activities started in 1955. After a five-year recess (1959-1963) the activities continued until 1965, when they were terminated definitely. A total of 45,000 tones of ore were dug out of the mine.
Mavridia was the first mine in the Kalavasos area where modern mining began in 1937.
Petra Mine, operational from 1953 to 1966, had one of the largest deposits in the region, with 290,000 tons extracted during its operation.
