yep they did us a huge favour finding iron sulphides that's were gold is usually found and gold is all 100% ours


Gold-Pyrite ores

Gold has varying modes of occurrence in sulphide ores ranging from being disseminated and interstitial in minerals such as lead and copper, in oxide ores particularly as disseminated particles, and as free milling gold or association with tellurides. Where the gold is intimately associated with various sulphide minerals, especially iron sulphides which include pyrite, arsenopyrite and pyrrhotite, flotation recovery of the gold is dependent on recovery of the associated minerals. In this case gold follows the associated sulphide mineral recovery.
