Camp Colliery.
Camp Colliery (below) is on the Transvaal side of the Vaal River and was sunk during the years 1912 and 1913. A tunnel was driven under the river to connect with the Orange Free State Coalfield. Owing to the unsettled conditions caused by the War, operations at this Colliery were temporarily suspended in 1914. The Colliery is equipped with headgear, permanent winding engine, compressed air and rock drilling and boiler plant, with native quarters, etc.
