Chalcopyrite is a common mineral and is found in almost all sulfide deposits. Fine crystals of chalcopyrite have a unique character and can add to anyone's collection. As an ore of copper, the yield of chalcopyrite is rather low in terms of atoms per molecule.
Throughout human history, chalcopyrite has been our leading source of copper. This is despite having a relatively low copper yield (only 25% of its atoms are copper) compared to other copper minerals such as chalcocite and cuprite (both with 67% yields), or bornite and covellite (that have 50% yields).
