Brian Gilbertson

Non-executive Chairman

BSc (Hons), MSc, MBL, PMD45

In 1960, the Council for Scientific and Industrial Research (CSIR) awarded him a bursary to study at Rhodes University where, in 1963, he obtained a BSc degree, majoring in Mathematics and Physics. The following year he earned a BSc (Hons) in Physics. Following further study (part-time), he was awarded an MSc in Physics by Rhodes University in 1969 and an MBL by the University of South Africa in 1973. In 1983 he attended PMD45 at Harvard University.

From 1992, Mr. Gilbertson led the transformation of the South African conglomerate Gencor into a focused mining company. The industrial and financial interests were “unbundled” to shareholders, and large new capital investments (including Columbus Stainless Steel and the Hillside Aluminium Smelter) were successfully implemented. Gencor entered the international arena in 1994 via the US$1.2 billion purchase of the mining interests (the Billiton assets) of the Royal Dutch/Shell group. In July 1997, Gencor sold its non-precious metals interests to a new London-domiciled corporation, Billiton Plc. Billiton’s investments and acquisitions in the ensuing years (the Mozal aluminium smelter, the Worsley alumina plant, and the take-over of Rio Algom) culminated in the merger with BHP Ltd of Australia, on July 1, 2001, to create BHP Billiton plc. Mr. Gilbertson has also had active roles in the merger of the gold operations of Gencor and Gold Fields of South Africa, creating Gold Fields, a leader in the world gold mining industry, as well as the formation of Incwala Resources, a pioneering Black Economic Empowerment initiative in South Africa. He has also played a leading role in the October 2006 merger between Russian aluminum producers SUAL and RUSAL, and the alumina assets of Glencore, to form the world’s premier aluminium company. Mr. Gilbertson is currently the Chairman of Pallinghurst Resources LLP and a non-executive director of ASX-listed Jupiter Mines Limited, for which he has temporarily assumed the position of non-executive Chairman. Mr. Gilbertson has been a board member since December 2008.
