Harmony Gold Mine Welkom Contact Details
Harmony does not run a single “Welkom branch”: each of its Free State mines near Welkom has its own line, for example Tshepong North on 057 907 2113, Tshepong South on 057 916 7244 and Masimong on 057 910 5650. Harmony Gold Mining Company Limited’s Free State goldfields operations are Joel, Masimong, Target 1, Tshepong North and Tshepong South underground, plus the Central Plant Reclamation and Phoenix surface operations, while the head office is in Randfontein.
This page lists the Welkom area mine lines only. For Harmony’s company-wide numbers, see the main Harmony Gold Mine contact details page. Harmony is not the same company as Harmony SEA, which uses a different, unrelated website.

Services at this location
These are working gold mines, not customer service branches. Tshepong North mines the Basal Reef, with the B Reef as a secondary reef, and its ore is processed at the Harmony One plant. The phone lines above are the operations’ own numbers, so use them for matters that concern a specific mine.
