The basic raw material for the making of cement is produced in the Limestone Quarry of the Vasiliko Cement Industries. The Limestone Quarry operates since the very first years of the Cement Industry's establishment, in an area west of Kalavasos.
Mavridia was the first mine in the Kalavasos area where modern mining began in 1937.
Historically, this area also saw intensive mining during ancient times, as proven by the large accumulations of rust found in the region.
Petra Mine, operational from 1953 to 1966, had one of the largest deposits in the region, with 290,000 tons extracted during its operation.
