An area with many different types of mineral localities.

Located in the southern part of what is called the Entia Valley. Photographs on Mindat show aquamarine, clear, smoky and amethyst quartz crystals and sceptres, and chrysoberyl. These photographs are mainly by Patrick Gundersen, who uncovered the specimens from un-named pegmatites, in remote areas in the district. The Carrara mica mines are about 9 kilometres north-west of the Harding Springs location, containing muscovite, beryl, garnet, ilmenite, epidote, microcline, and amazon stone. No access track could be seen into these locations.

There are several ways to access the Harding Springs locations. It should be remembered that Harding Springs is located on a cattle station and permission should be sought before accessing.

1. One way is to contact the Ambalindum Station, and book into their accommodation. The homestead is 58 kilometres by station tracks south-west of the location. Then book a fossicking tour, where participants drive their own 4 wheel drive to a prospectors shack near Mount George, and are taken to a couple of selected sites to fossick. Permission to wander across the countryside looking for undiscovered treasures may not be given.

2. Another is accessing from the Plenty Highway. At the time of writing (2017) travellers will come across signs from the station threatening to prosecute anyone with trespass. Just after the Entire Creek crossing on the Plenty Highway, head on a track south. Go 22.7 kilometres south to Inkamulla Well. Take the track east approximately 15 kilometres, then the right fork south. The track crosses the wide Huckitta Creek, turn briefly east, then south again, reaching the Quartz Hill cattle yards a total of 31.4 kilometres from Inkamulla Well. Go a further 3.7 kilometres south to Coggan Bore. Opposite the bore, take the track south-west, which then heads west to Harding Springs a total of 22.5 kilometres from Coggan Bore.

3. At Inkamulla Well above take the track west 12.1 kilometres to Spriggs Creek Bore. This will require a crossing of the creek just before the bore. Take the track south south-west 27 kilometres, until a track heading west to the homestead is reached. Remain on the track that turns east for another 16.7 kilometres.

Harding Springs is nothing more than a well and cattle yard. A house, possibly the prospectors shack mentioned above is 4.3 kilometres west of Harding Springs, and one kilometre north of the track along a fence line. Availability of water in the district is not guaranteed, as wells can remain on maps long after they become derelict. Neither is there a guarantee the shack will be occupied. The area is remote, mountainous, largely waterless, with no help nearby.
