Pegmatites

Hydrokenoelsmoreite was approved in 2003 as a new mineral and named "elsmoreite". In 2010 it was redefined and renamed "hydrokenoelsmoreite".

Localities

At the type locality, the Elsmore Tin Mine, Elsmore, Gough county, New South Wales, Australia, hydrokenoelsmoreite was formed as a result of the oxidation of ferberite in the oxidised zone of weakly mineralised granitic pegmatite dykes containing tin, tungsten, molybdenum and bismuth minerals (Webmin, AJM 13.1.51). Associated minerals include quartz, white mica, cassiterite, arsenopyrite, native bismuth, chalcopyrite, ferberite and molybdenite (HOM).

At the Drakelands Mine, Plympton, Plymouth, Devon, England, UK, hydrokenoelsmoreite is associated with wolframite and quartz (HOM).
