This excursion will pass through the Transvaal Sequence floor rocks into the Bushveld Complex granites near Vergenoeg Fluorite Mine. After passing the town of Chuniespoort and the Mohlopitse fold belt, the tour proceeds to the northeastern limb of the Bushveld Complex to view the Lower and Lower Critical Zone rocks in the Olifants River Trough and along the Cameron Section.

The famous platinum orebody of the Merensky Reef will be inspected at the Maandagshoek type locality, close to Burgersfort. The exposures of the middle and upper group chromitite layers will be visited at the Tweefontein Mine and at the Dwars River
gorge, which is a national geological monument and is situated south of Steelpoort.

The discordant ultramafic pipes will also be viewed. The Main Magnetite Layer and related iron–vanadium–titanium mineralisations of the Upper Zone of the Bushveld Complex will be visited in Sekuhuneland.
