The Mines and Works Amendment Act No. 25 of 1926, also known as the Colour Bar Act, revised the 1911 Mines and Works Act and reinforced the color bar in the mining industry. The result of the 1922 Rand Revolt, when mine owners attempted to replace white workers with lower paid Blacks (they earned about one tenth of the amount). This act also excluded Indian miners from skilled jobs.
Repealed by the Mines and Works Amendment Act No 27 of 1956
