Saléeite is a secondary mineral occurring in the oxidised zone of uranium-bearing polymetallic hydrothermal and sedimentary mineral deposits, associated with torbernite, autunite, zeunerite, bassetite, dewindtite, sabugalite, phosphuranylite and dumontite (Mindat,HOM).

At Tom's quarry, Kapunda, Mount Lofty Ranges, South Australia, saléeite is associated with fluellite, aldermanite, wavellite, cacoxenite, apatite and minyulite (AJM 17.1.25).

At the type locality, the Shinkolobwe Mine, Kambove District, Democratic Republic of the Congo, saléeite is found intergrown with torbernite and associated with dewindtite and other uranium phosphates (AM 19.36, Mindat, Dana).

At Schneeberg, Saxony, Germany saléeite occurs in a limonite-rich rock with uranophane and zeunerite (Dana, AM 35.525-530).

At Gull mill, Fall River county, South Dakota, USA, saléeite is found disseminated in carnotite-bearing sandstone (Dana).

At Cave Hills and Slim Buttes, Harding county, South Dakota, USA, saléeite occurs in lignite (Dana).
