There are five operational surface mines at Evia. The mines have modern surface earthmoving equipment, two ore grinding units, two ore beneficiation units, separation using heavy media and one magnetic seperator, a homogenization yard and ship loading installations.

Transportation of ore from the grinding unit to the enrichment and homogenization installations is by an integral 7.5km conveyor belt system, which also takes advantage of the altitude difference to produce electrical energy. Annual production is 1.2 to 1.5 million tonnes of ore. Average nickel concentration is 1%-1.03%.
