Union Corporation Limited is a South African mining house founded on 29 December 1897 as A Goerz & Co Ltd. It took over the interests of the British registered company founded by Adolf Goerz in 1893. The company was renamed Union Corporation in 1918.
The company owned the East Geduld and Modderfontein Deep Levels mines. In the 1950s, it opened four mines in Evander and the St Helena mine in the Orange Free State.
Key personalities included Henry Strakosch, who was appointed Managing Director in London in 1902 and Peter Maltitz Anderson, who joined the company in 1911 and became Manager of UCL in 1921.
In 1980 the group merged with General Mining and Finance Corporation to form Gencor, which was in turn amalgamated with Gold Fields in 1998.
