Humans can smell hydrogen sulfide gas, the smell of rotten cabbage, in the parts per trillion range.
The sulfur caused microstructural changes and the presence of sulfide particles, which acted as preferential fatigue initiation sites.
Widely scattered massive sulfide intersections, however, demonstrate considerable exploration potential.
Most economic deposits of non-ferrous metals occur as sulfide minerals e.g. galena, PbS; sphalerite, ZnS; chalcopyrite, CuFeS 2.
The deposit also contains minor molybdenum occurring locally as the sulfide, molybdenite (not found here ).
