Mining Terminology Twin Metals

MINING Mining begins with the mineral bearing ore (material with positive economic value) removed from the earth. In reaching the ore, developmental rock is also removed and used for barricading areas or to fill voids underground. Mining at the TMM project would occur below the ground surface from hundreds to several thousand feet.
