Researchers found autunite inside the Daybreak Mine on [[Mount Kit Carson]], [[Spokane]], [[Washington (state)|Washington]] (or sometimes referred to as "near [[Mount Spokane]]"), in "[[Vug|vugs]], [[Fracture (geology)|fractures]], and [[Shear (geology)|shear zones]] in [[Granite|granitic rock]]". These areas showed signs of another phosphate, [[apatite]], which may have helped lead to the formation of autunite, by providing a source of [[phosphate]] and [[Lime (material)|lime]]. The formation may have occurred with the interaction of uranium leached from a separate deposit.<ref>{{Cite book|title=Autunite from Mt. Spokane, Washington|last=G. W.

90,000&nbsp;lbs of [[Triuranium octoxide|U<sub>3</sub>O<sub>8</sub>]] were produced from nine properties, although most of the ore came from the Daybreak Mine.<ref>[http://pubs.usgs.gov/of/1998/of98-503/of98-503.pdf USGS]</ref>

=== Other locations ===
One of the other locations of autunite includes Autun, France, the type locality and namesake of the mineral. The mineral was formed there as an [[Mineral alteration|alteration]] of [[uraninite]] and other [[uranium]] bearing minerals.<ref>{{Cite book|url=https://books.google.com/books?id=BmcirNqupXcC&pg=PA149|title=Nature Guide: Rocks and Minerals|last=Publishing|first=D.
