Abstract: The results of studying natural samples of CuFeS$_{2}$ chalcopyrite mineral from hydrothermal ore manifestations of island arcs of the Pacific Ocean by $^{63}$Cu nuclear magnetic resonance ($^{63}$Cu NMR) in a local field at room temperature are presented. The asymmetric shape of the detected resonance lines in the $^{63}$Cu NMR spectrum indicates the presence of at least two overlapping lines. The presence of two overlapping central components can be a consequence of the occurrence of regions with different types of structural distortion near the resonant nuclei. These results show that the pulsed $^{63}$Cu NMR method can be an effective method for studying the physical properties of deep-sea polymetallic sulfides of the global ocean.
