Chalcopyrite name come from greek χαλκóσ (chalkos) or cooper and pyros or fire; Pyrite Cooper. It's a copper iron sulfide mineral that crystallises in the tetragonal system. It has a brassy to golden yellow colour and a hardness of 3.5 to 4 on the Mohs scale. Chalcopyrite is the most important copper ore. Chalcopyrite ore occurs in a variety of ore types, from huge masses as at Timmins, Ontario, to irregular veins and disseminations associated with granitic to dioritic intrusives as in the porphyry copper deposits of Broken Hill, the American cordillera and the Andes. The largest deposit of nearly pure chalcopyrite ever discovered in Canada was at the southern end of the Temagami Greenstone Belt where Copperfields Mine extracted the high-grade copper.
