The Eva Copper project will employ conventional open-cast mining methods, including drilling, blasting, loading and hauling. A construction period of two years is envisaged, including one year of pre-production mining. Mining activities would be based on open pit mining of the Little Eva deposit at a rate of 31,200 t/d of ore.
