Abstract: The results of investigating natural samples of chalcopyrite mineral CuFeS$_2$ from massive oceanic sulfide ores of the Mid-Atlantic ridge by the $^{63}$Cu nuclear magnetic resonance (NMR $^{63}$Cu) in a local field at room temperature are presented. The significant width of the resonance lines found in the $^{63}$Cu NMR spectrum directly testifies to a wide distribution of local magnetic and electric fields in the investigated chalcopyrite samples. This distribution can be the consequence of an appreciable deviation of the structure of the investigated chalcopyrite samples from the stoichiometric one. The obtained results show that the pulsed $^{63}$Cu NMR can be an efficient method for studying the physical properties of deep-water polymetallic sulfides of the World Ocean.
