Abstract Gold is an important constituent of many carbonate-hosted massive sulfide ores of the Colorado mineral belt. Within the Leadville district of the Colorado mineral belt gold has been recovered in substantial amounts from such ores. A detailed petrographic and electron mi-croprobe study of one such Leadville orebody, the Black Cloud 3, was undertaken in order to characterize the gold occurrence. Three styles of gold occurrence, including a complex Au-Ag-Bi-Te mineral assemblage, are documented. Gold occurs in the massive sulfide ore as native grains contained predominantly in pyrite, as electrum grains contained within cross-cutting sulfide veinlets, and as electrum and Au-Ag tellurides included in a bismuth-tellurium mineral assemblage also containing hessite (Ag 2 Te), tellurobismuthite (Bi 2 Tes), volynskite (AgBiTe 2 ), chalcopyrite, galena, quartz, matildite (AgBiS 2 ), and coloradoite (HgTe).
