Trans Hex was established in 1965 by a number of entrepreneurial investors who wanted to explore a diamond-mining concession in the Namaqualand region of the Northern Cape. The Company was subsequently appointed as a contractor to the then Small Business Development Corporation of South Africa to prospect for diamonds on the State-owned Komaggas farm, which it went on to mine profitably for more than 20 years.
In the ensuing decades, Trans Hex’s assets and expertise grew rapidly through the acquisition of numerous diamond-mining companies in Southern Africa and further afield. Among these acquisitions were the projects which today comprise the Company’s Lower Orange River Operations – Baken Mine in 1972 and Bloeddrif Mine in 1984.
The Company was listed on the JSE Limited in 1981.
In 2010, the Company acquired a 33% stake in the Luana project (Somiluana Mine) in Angola.
In 2012, Trans Hex partnered with investors to form a new joint-venture company, West Coast Resources (Pty) Ltd (previously known as Emerald Panther Investments 78 [Pty] Ltd), which finalised its acquisition of Namaqualand Mines from De Beers in 2014. Mining operations commenced in 2015.
