Mount Gee is located in the northern Flinders Ranges within the Arkaroola Wilderness Sanctuary, and is part of the Mount Painter inlier. It was named after a mining warden, Lionel Gee.

Recently Mount Gee came to prominence in 2008 - 2011 because of uranium exploration occurring in an area that was commonly (and mistakenly) believed at that time to be protected from all mineral exploration. This situation was altered in 2011 - 2012 when the Government of South Australia created the Arkaroola Protection Zone and passed the Arkaroola Protection Act (2012) which prohibits all mining activity in the Arkaroola Protection Zone.

With its peak rising 600 metres above sea level Mount Gee is one of several peaks located in the visually spectacular and geologically significant range north-east of the Gammon Ranges and south of the Mawson Plateau. Mount Gee was entered on the Register of the National Estate in 1982 due to its "spectacular mass of quartz crystal and vughular, lining the cavities of crush breccias".

Mineral exploration in the Mount Painter region began in the 1860s with the discovery of copper at a number of sites in the region, including the Yudnamutana copper field and the Lady Buxton mine, and numerous small diggings throughout the Mount Painter area. Professor Sir Douglas Mawson first identified samples of torbernite (a copper uranium phosphate mineral) in samples brought to him in 1910 by the Greenwood brothers from what is now called Radium Ridge. Various syndicates were formed in 1911–1935 to try to exploit the radium from Radium Ridge (immediately to the west and adjoining Mount Gee). During World War II investigations into the area of Mount Gee-Mount Painter were carried out by the Commonwealth Government, and the No.6 workings (see adjoining photo) was developed, as well as a number of workings in the East Painter Gorge (immediately to the north of Mount Gee-Mount Painter) and Yudnamutana Gorge. Sporadic exploration occurred during the 1950s adjacent to Mount Gee, culminating in the efforts of Exoil NL and Transoil NL during the late 1960s and early 1970s. It was during this exploration phase that the "Ridgetop" track was constructed. The numerous exploration tracks across the southern and north-eastern faces of Mt Gee were constructed by Exoil-Transoil at this time. Exploration ceased during the 1970s as a result of large uranium finds elsewhere and the "Three mine policy" introduced by the Federal Government in the early 1970s. CRA resumed exploration in the area during the early 1990s, focusing on the Streitberg Ridge and Armchair Basin areas, immediately to the north of Mount Gee, as well as other areas within the Arkaroola Sanctuary. Bonanza Gold Ltd pegged an exploration license over the Mt Gee area in the early 2000s. Several exploration holes were drilled into the Mount Gee-Mount Painter area before Marathon Resources took over the project and intensified the exploration efforts, focusing once again on the southern and northeastern sides of Mount Gee, by opening up many of the (still existing) Exoil-Transoil tracks. None of the uranium deposits have been proven to be economic, although Marathon Resources claim that the Mount Gee deposit complies with a JORC inferred and indicated resource of 31,400 tonnes of U₃O₈, potentially the sixth largest known uranium deposit in Australia.
