Group of 7 stereoviews depicting gold mining operations around Johannesburg, South Africa, focusing on the large industrial complexes associated with the Witwatersrand gold fields. The images show miners sorting quartz ore, workers gathered around machinery, and underground scenes where laborers drill and extract ore from narrow tunnels supported by timber beams.

Additional views present extensive processing facilities including concentrating pans, stamping mills, and large mechanical plants used to crush and refine gold-bearing rock. Several scenes show groups of miners and laborers working in confined underground passages illuminated only by limited light, emphasizing the difficult conditions of early industrial mining.

Produced primarily by the Keystone View Company, these stereographs were widely circulated as part of educational series illustrating major industries around the world. The photographs provide a detailed visual record of early twentieth-century gold mining technology and labor practices in one of the most important gold-producing regions in history.
