Krennerite is found in hydrothermal gold-tellurium deposits with other tellurides (Webmin, HOM). Associated minerals include
gold, pyrite and
At the South Kalgurli mine, Kalgoorlie-Boulder, Western Australia, krennerite has been found in association with calaverite (AJM 18.1.13).
At the Emperor Mine, Vatukoula, Vatukoula Gold Field, Viti Levu, Fiji, small sharp krennerite crystals occur in and on native gold (R&M 96.3.207).
At the type locality, Săcărâmb, Deva, Hunedoara, Romania, small specimens of gold associated with krennerite have been collected (R&M 96.3.207).
At the Cripple Creek mining district, Teller county, Colorado, USA, krennerite is sometimes intergrown with calaverite and embedded in celestine on pyritic quartz gangue (Minrec 36.2.173).
