A proper coat of arms was designed in the 1960s. It was registered with the Transvaal Provincial Administration in November 1965 and at the Bureau of Heraldry in January 1969. The arms were : "Per chevron ploye Azure and Or, dexter two mine hammers in saltire and sinister a cogwheel all Or, and in base the Paardekraal Monument Gules". In layman's terms, the shield was divided by a curved chevron-shaped line into blue and gold, displaying two crossed mine hammers and a cogwheel at the top, and the Paardekraal monument at the bottom. The crest was three horses' heads issuing from a golden mural crown; the supporters were an eland and a gemsbok; and the motto was "Labor omnia vincit improbus".
