Obituary
Brian Patrick Gilbertson
1943-2025
By Peter Thompson, co-author of The Big Fella: The Rise and Rise of BHP Billiton.
Brian Gilbertson, the South African mathematician, scientist and international industrialist who has died in South Africa aged 82, was for many years one of the world’s leading miners. A tall charismatic figure with a rough-hewn face and a boyish grin, he was also a nuclear physicist with a love of opera, squash and cycling, and an encyclopaedic knowledge of Greek and Roman classics. In a 50-year career, the Law of Unintended Consequences, in which he was a firm believer, took him from a tiny village near Bothaville in the heart of Afrikanerdom to the highest levels of the corporate world.
As one of mentor Derek Keys’ ‘young lions’ at the South African precious metals specialist Gencor, Gilbertson knew all about gold and platinum but on a trip to Brazil in 1990 he saw gigantic shovels scooping tonnes of high-grade hematite iron ore from the Carajás open-cut mine in the state of Pará and realised that Gencor would have to diversify into base metals like iron ore, nickel and bauxite if it were to join the major league of miners.
The 1990s had ushered in what has been called the Magnetic Age in which the producers of natural resources were drawn together in voluntary alliances or were swallowed up by even bigger predators, leading to the formation of the mega-mining companies BHP, Rio Tinto and Anglo American. Gilbertson’s first coup was the purchase of Billiton, founded as a tin-mining company on the Indonesian island of Belitung, from Royal Dutch Shell in 1994. Billiton would lead the breakout from the collapsing apartheid barriers of South Africa in the 1990s and bring Gencor’s principal mineral assets to the world markets.
On 1 July 2001, Gilbertson curated Billiton’s merger at a premium for its shareholders with BHP Ltd of Australia to create the dual-listed colossus BHP Billiton, the biggest diversified miner the world had ever seen. Appointed Chief Executive in Melbourne on 1 July 2002, his first move was to approach Sir Robert Wilson, Chairman of Rio Tinto, with ‘Project 6’ (a reference to Rio’s headquarters at 6 St James’s Square) to merge the two mining titans. When presented with the agreed headline terms, the BHP Billiton Chairman, Don Argus, riled by the idea that the combined group would be London-based (and therefore no longer ‘The Big
Australian’), objected to having been excluded from the talks and, on 4 January 2003, Gilbertson resigned following a BHP Billiton board meeting from which he had been excluded. A joint media release cited “irreconcilable differences” and his sudden departure from the helm of BHP Billiton remains one of the most controversial incidents in Australia’s corporate history.
Brian Patrick Gilbertson was born in George on the ‘Garden Route’ of South Africa’s Western Cape on 15 August 1943 and was schooled in the Free State’s Bothaville. “My father went out to South Africa from London as part of a bomber squadron during the war but he was from an Irish background in Cork,” he told this obituarist in a 2008 interview. “He met my mother in South Africa.” The Gilbertsons moved to London when he was a child but his mother found the climate unpleasant so his father joined the Department of Water Affairs in the high plains of the Free State. “They were building a water supply scheme to supply water to the Free State goldfields which were just opening up,” he said. “I actually grew up in this tiny village – I don’t think there were 20 houses. Bothaville was a ‘big’ town: it had about 30 houses. My mother was Afrikaans but we actually spoke English at home; my father never learned Afrikaans but my schooling was in Afrikaans.”
The young Gilbertson was fortunate to have had a great mathematics teacher who spotted his aptitude for science. After matriculation, he studied physics and mathematics at Rhodes University on a bursary from the Council for Scientific and Industrial Research (CSIR). He did the fourth year – the honours year - in physics and then joined the CSIR to repay his bursary. “They posted me to the Institute for Rocket Research – great stuff for a young man,” he said.
At the time South Africa was under siege internationally for its apartheid policies. “Nobody would sell any weaponry to the country except the French. There was a joint project with the French Government to build a rapid reaction surface-to-air missile system. To my great good fortune, instead of being sent to the army I ended up in the team that was posted to Paris to work on this missile system. I had one of the best times of my life. Instead of marching up and down with a gun on my shoulder in South Africa in basic training, I was in Paris with the bright lights and they actually paid us a very generous salary. I was able to save enough to buy my first car. I was in Paris for not quite a year and then went back and worked with CSIR.”
In 1970, Gilbertson married his fiancée, Rensche Fouché, and the couple had two sons, Sean (b. 1972) and Quinton (b. 1974). New opportunities enabled him to combine his scientific expertise with a growing understanding of the mining industry, firstly with the South African mining group JCI, which hired him to find new mineral deposits. “I became a minor expert in a field of mathematics called pattern recognition,” he said. He was soon flying around the wilds of South Africa with an exploration unit searching for mineral deposits using multi-spectral remote sensing. “We were trying to identify whether particular vegetation or rocks had signatures which would indicate gossans, for example, which would indicate there was copper down below. This was becoming a very topical area of research and NASA launched what was called the Earth Resources Technology Satellite No 1 which flew around with scanners imaging like a television set but in very narrow parts of the spectrum.” Gilbertson was appointed one of 70 NASA investigators around the world and his little laboratory in South Africa received the first data transmitted from the new satellite. “We got the first pictures of the Great Dyke and I took them along to a symposium in Washington,” he said. “The geologists were gobsmacked – they’d never seen anything like this from space – it was very exciting.”
After 16 years with JCI, Gilbertson joined Derek Keys, a 55-year-old accountant who had been drafted in as chairman and chief executive of Gencor in 1986 to give the great sprawling conglomerate a new image and a new direction. Keys and Gilbertson created General Mining – Genmin – to house the mining arm, which included 14 gold mines, the base metals group Samancor, the platinum producer Impala, the coal group Trans-Natal (later called ‘Ingwe’) and a big minerals division. Two years later Gilbertson was appointed chairman of Genmin.
Keys decided Gencor should seek new opportunities offshore, even though it would have to operate covertly through third parties, usually Australian or British, because of his country’s pariah status. So Gilbertson and other key executives were sent abroad to study new technologies and to seek out possible mining prospects in South America and Australia.
On 2 February 1990, F. W. de Klerk announced the epochal decisions to lift the ban on the African National Congress and other proscribed organisations, end the state of emergency and release Nelson Mandela from prison, thus signalling the end of apartheid and opening the way for a new constitution based on the principle of one person, one vote. Keys was appointed to the crucial role of Finance Minister and, to his surprise, Gilbertson was chosen as Keys’ successor at Gencor. In the goldfish bowl of South African mining, he was still regarded among his more conservative rivals at Anglo American and De Beers as something of an upstart, whom they nicknamed “The Big G”. According to the Economist, ‘staff would greet Gilbertson’s arrival by helicopter by declaring that “the ego has landed”’. But the helicopter pad had been on Gencor’s roof in the heart of Johannesburg for the previous 40 years and Gilbertson was simply continuing a company tradition by using it. The difference was that the helicopter now had twin Messerschmitt engines and state-of-the-art avionics.
While his sudden resignation from BHP Billiton in 2003 would attract huge headlines in the business world, it also opened up enticing new avenues. From May that year Gilbertson was an adviser to the board of Lonmin Plc, a UK-listed South African platinum producer undertaking major strategic changes. Consequently, he initiated the formation, in September 2004, of Incwala Resources, a pioneering Black Economic Empowerment platinum initiative in South Africa, and was its first Chairman until March 2006.
In late 2003, he also led the mining group Vedanta Resources Plc to the first primary listing of an Indian company on the London Stock Exchange in the second-largest IPO of that year (at USD 876 million). He served as Chairman of Vedanta until July 2004 and the following month he joined SUAL, the smaller of Russia’s two aluminium producers, as President. In March 2007, he led the company into a merger with RUSAL, the larger Russian aluminium producer, and the Glencore alumina arm, creating the world’s foremost aluminium company.
Meanwhile, in 2006, Gilbertson had established Pallinghurst Resources, a specialist investment vehicle in the natural resources sector named after a tree-lined street near his former home in Westcliff, Johannesburg. Operating from 54 Jermyn Street, London, Pallinghurst made three principal investments: in Sedibelo, a platinum deposit north of Pilanesberg, South Africa; the Tshipi manganese mine in South Africa’s Northern Cape (via Jupiter Mines Ltd of Australia); and Gemfields/Fabergé which became the world’s largest miner of emeralds and rubies. He stepped down as Chairman of Pallinghurst in March 2021.
Over the years Brian Gilbertson won many awards: he was named Communicator of the Year in 1991; the Business Times’s Businessman of the Year in 1994; the Witwatersrand Business School Management Excellence Award in 1996 for “consistently demonstrating high levels of leadership”; and, in 1997, the Frans du Toit Medal from the South African Academy for Science and Art for his “creative contribution to the South African economy”; and the Business Day’s Business Achievement Award “acknowledging Gencor’s single-minded strategy under (his) chairmanship to become a world-class natural resources group”.
In 1998, he was awarded the Brigadier Stokes Memorial Award of the South African Institute of Mining and Metallurgy for his “outstanding and unique contribution to the South African Mining Industry over a long period” and the gold medal of the Institution of Mining and Metallurgy (London) for “distinguished services to the international minerals industry”. The University of the Free State conferred an honorary Doctor Commercii in 2001, and Rhodes University an honorary Doctor of Law in 2004.
After a long illness, Brian Patrick Gilbertson died at home in South Africa surrounded by his family on 17 December 2025.
Media Coverage
I interacted with him a lot during my 40-odd year career as a mining journalist and, not only did he deliver the goods on some huge and ground-breaking deals, but I found him a professional to deal with as a journo.
That’s because – unlike some of his peers – you could get to him. If you asked him a good question you invariably got a good answer. If you asked him a stupid question you would probably get handed your head on a plate.

Brian Gilbertson, former chairman of Gemfields, died aged 82 on December 17 after a long illness, the company said last week.
Gilbertson stepped down as chairman and director of the company in 2019. His son, Sean, joined the company in 2017 and became CEO in 2018.
As CEO of Billiton in 2002, Gilbertson helped merge the company with BHP to become the world’s largest mining company at the time. He worked for BHP Billiton and its preceding companies for over 32 years. In 2003, he resigned from the mining giant.
Gilbertson received the Brigadier Stokes Memorial Award in 1998 for his unique and outstanding contribution to the South African mining industry.
He died in his home in South Africa surrounded by family.
Gilbertson passed away at his home in South Africa on Wednesday after a long illness, his family said in a statement. He’s survived by his wife Rensche, sons Quinton and Sean, and five grandchildren.
The 2001 merger between Billiton and BHP created the world’s largest mining company. Gilbertson, who resigned in 2003 because of “irreconcilable differences” with the company’s directors, went on to hold several other leadership positions in the corporate world.

“Death devours all lovely things’, Millay.
BPG was a wonderful person, so very smart and one of the most thoughtful and kind people I have ever known.
One of the things he loved to do was throw curve balls to challenge people and he knew how to get the best out of them. When he asked you to complete a task, he did it with this subtle smirk. He taught me so much and believed in my ability and knowing that if he challenged me with any task, that I would succeed. He believed in people and their abilities to get a job done.
You always knew when he was coming as you would hear him whistling down the hallway. He always loved to get on his bike and ride, had a love for the opera and the arts and his favourite place was his beloved Plettenberg Bay.
BPG will be missed every day but will be forever in our hearts and never forgotten. May he rest in peace.
My deepest and heartfelt condolences to Rensché, Sean, Quinton and families.
My one lifelong memory of Brian is sharing a lift ride down with him and Sean at their apartment in London. Sean, myself, and Sabine had all studied at WITS together and had recently just founded globalCOAL - the online coal marketplace in the late 1990's. His advice was along the lines of: "Remember that money in, is better than money out. So if you're not making it, don't spend it."
His wry grin and humour, great intellect, and rock-firm support of his family will no doubt be sorely missed. May his soul now find ever more quests to enjoy, and may his family find peace in knowing they could share and love, and be loved by him for awhile. So mote it be.
Brian will always be one of the most influential people in my life. He taught me more than I think he ever realised. He remains my inspiration, role model, boss, mentor, coach and friend. I have no words to express my deep felt gratitude for every second I had the privilege of being in his presence. He will always live forever in the hearts, minds and souls of those he walked among, and whose careers he developed and made great. We have not lost him, he is eternal. Let’s celebrate him forever.
I met him on my first business trip as an investment banker at Goldman Sachs in 1993. He commanded respect from everybody - not by forcing it, but by earning it.
He will forever be remembered for how he turned Gencor into Billiton and then BHP-Billiton. This will go down in the history of the resources industry as one of the most value-accretive and strategically astute transformations, creating the world’s most complete and valuable mining company.
After that, he created the world’s largest aluminium producer as well at the largest Indian mining company. Always looking five moves ahead on the chessboard!
With that mentality at mind, it is hardly surprising that he became the mastermind behind the genesis of private equity contributions to the resources sector.
He saw it coming and wanted to be a pioneer on that front too. That lead to the birth of Pallinghurst. Together with his son Sean Gilbertson, Priyank Thapliyal, Andrew Willis and myself, we built one of the first private equity platforms for the mining sector. It has BPG who identified the Chinese steel boom, Platinum Group Metals, coloured gemstones and metals used in the “EV revolution” as sectors of focus. Fast forward, over the next almost 20 years, over $3bn of strategic equity capital was deployed into our investments, creating thousands of jobs and local upliftment in the process.
Traveling with BPG was always something special. Given his status, it was very much like being a U2 band member traveling with Bono. This was especially the case when we travelled to Australia. That continent’s fascination with BPG was something! Whenever we arrived in Sydney, Melbourne or Perth we were met by photographers and “journos” as the Australians call their journalists. After the long travel and the meeting with the press, Brian was always up for some exercise! Typically, that would involve 50km of cycling on bikes already prepared for our arrival. I have to admit that even though I am almost 25 years younger than Brian, I was the one following his wheels.
I will always be grateful for what BPG has given me, and the standards he created. Living up to those will be the goal for not only me, but everybody having had the privilege of working with BPG.
Lastly, my heart goes out to Rensché, Sean and Quinton. May time heal your pain and Brian’s achievements make you forever proud.
Arne Frandsen, Chairman, Pallinghurst
It was a sad day for all of us when he parted ways with BHP Billiton and I have often wondered what might have been had this not occurred....
RIP Brian.
Hazel and I extend our condolences to Rensche, Sean, Quinton and family.
Richard Pilcher
His success in his business life was stratospheric and is extremely admirable. His sharp mind and wit were evident, as was his pride in his family.
I had the great privilege of working for Brian at Rustenburg Platinum (now Valterra) and then indirectly at Gencor. Brian was a most dynamic, insightful person – never took “can’t do” as an
answer, always researched deeply, interrogated the outcomes, and made a decision.
He was a hard but fair task master, always asking, no – demanding, the best of everyone who worked with or for him, and generous in his support and recognition of a job well done. So Brian pushed us to full capacity, to realise our particular talents and to raise our games. Mediocre was not a word in his vocabulary.
My years at Rustenburg and subsequently at Gencor were amongst the most happy, exciting and fulfilling of my career. Without Brian’s input and guidance I would not have had such a wonderful and varied working life. Thank you BPG/OBL.
Vivienne Mennell
I will forever remember Brian as the spearhead of corporate action - M&A, unbundling Gencor, dual-listing Billiton and ultimately its emergence as BHP Billiton.
BPG's skillful contextualisation will be his legacy - be it seeing opportunity, reading the resource cycle, noting tension in the board room, or observing one's "cabalistic choice of tie'.
We also shared mutual appreciation of classical music, opera, African artists, and architectural restoration, amongst others, which led to his generous support of a plethora of causes.
After his accomplished and fulfilling life, it is heart warming that Brian's years ended with the open skies and blue seas of his beloved Plett, surrounded by his family.
MHDSRIP. My deepest sympathy and condolences to Rensche and the family.
With much love, Martina
Brian always struck me as a very kind, decent and understanding man, although I do recall telling one or two people that I thought he had a streak in him than might urge him to cross the street to get INTO a punchup if he spotted one going!
He had an eye for the theatrical too as witnessed by his launching of the Fabergé website at a press ceremony with the go-live point timed for 9 minutes and 9 seconds past 9am on 9th September 2009 to the background of Beethoven's 9th Symphony (Ode to Joy movement).
I know he touched a great number of people in a great number of industries and professions. The world is a better place for his time here.
My best wishes and heartfelt condolences go out to the family.
Kevin Mutch
Former Legal Director Fabergé/ Gemfields 2007-2017.
I had the privilege of meeting him in Johannesburg during the Annual Board Meeting October 2018, where his openness and clarity of thought were immediately evident.
Our discussion was insightful and intellectually engaging, reflecting his strategic depth and practical wisdom.
He encouraged constructive dialogue and listened with genuine respect.
He will be remembered with great admiration as a principled leader whose legacy will continue to inspire.
My sincere condolences to Rensche and the family. While I have numerous memories of him, my first was being nervous going to meet him as a 28 year old at the Billiton offices in Strand to discuss Founding Chairmanship of Vedanta. He immediately put me at ease and that kickstarted my association with him. I worked with him through much of my career and learned an enormous amount. Though I was fortunate to be exposed to many successful people, I have never encountered anyone quite like him — firm, fair, and generous in equal measure. He trusted people, allowed them to get on with the job, and stood firmly behind difficult decisions, regardless of opposition.
He lived his life fully and left a lasting mark. Few can truly claim that. He will be deeply missed and fondly remembered.
May he rest in peace.
Priyank and Priyanka Thapliyal
Brian Gilbertson was, quite simply, a titan of mining — a leader whose vision, discipline, and sheer force of intellect reshaped companies, markets, and careers across continents. Over several decades, he stood at the helm of some of the world’s most significant mining enterprises, leaving an indelible imprint on the industry and on all who had the privilege of working with or learning from him.
Renowned for his uncompromising standards, strategic clarity, and deep operational understanding, Brian possessed a rare ability to see both the detail and the bigger picture. He was decisive yet analytical, demanding yet fair, and relentlessly focused on value creation. His leadership helped transform complex, capital-intensive businesses into globally competitive and resilient organisations.
Beyond balance sheets and production metrics, Brian was a builder of institutions and people. He mentored generations of executives, challenged boards to think more boldly, and never shied away from difficult conversations in pursuit of long-term sustainability and excellence. His influence extended far beyond the companies he led — shaping governance norms, capital markets confidence, and the professional standards of modern mining leadership.
Those who knew him will remember not only his formidable presence and intellect, but also his wit, candour, and deep commitment to the industry he loved. He believed in mining as a force for development, opportunity, and progress — and he dedicated his life to ensuring it was led with rigour, responsibility, and ambition.
Brian Gilbertson leaves behind a legacy measured not only in corporate milestones and shareholder value, but in the countless leaders he inspired and the enduring institutions he helped build.
He will be deeply missed, but his impact will endure for generations.
May his legacy continue to shape the industry he so profoundly influenced.
Our sincere condolences to the Gilbertson family and friends.
Kwape and Pinky Mmela
Despite his stature and achievements, he was known for his humility and willingness to listen, ensuring that every voice was heard. He fostered a culture in which ideas were encouraged and respected. His wisdom and inclusive leadership will be remembered with deep respect and gratitude.
He leaves behind a legacy of integrity, principled leadership, and lasting influence that will continue to inspire all who had the privilege of working with and knowing him.

Be comforted by the memories of a singular human being, a great South African and a titan of the mining industry as you mourn your great loss.
My deepest condolences to you and your family.
But Brian was never only about work.
Those of us on the fourth floor of the BHP Billiton building at 6 Holland Street will remember how he arrived early, often before the day had properly begun. Long before you saw him, you heard him. From down the corridor came the sound of Brian whistling Chopin or any other great classical piece, light and unhurried, as the office slowly came to life.
It was a small thing, perhaps, but it captured so much of who he was — thoughtful, disciplined, quietly joyful, and deeply human. I feel privileged to have worked alongside him and to carry these lessons with me.
Ulandi Langhein
We were shocked and saddened to hear today of Brian’s passing. We are so sorry and are thinking and praying for you and the whole family.
We will remember him with every fondness. He was a great man and we are very lucky to have known him.
It is hard to understate what a significant impact he has had on us all. We will treasure all the memories we had with him.
One such treasured memory is one of the earliest photos on my iPhone, of the Christmas Day we shared in Plettenberg Bay in 2011.
Please accepted our deepest condolences from Sacha and I.
Andrew
I will always remember a quiet one-on-one conversation I shared with him in a boardroom shortly after a board meeting. Canapés were being passed around, champagne poured and amid the formality he leaned over and asked me, quite seriously, how long it would take to create a piece of high jewellery.
I replied, “Around six months, Mr Gilbertson.”
Under his breath, with unmistakable dry humour, he responded, “I can build a smelting facility in the middle of f*****g nowhere in less time than that.”
He followed this with a wry smile and just as quickly the boardroom formality returned. It was a small moment, but one I'll never forget and to this day, I still don't know how to respond.
Antony Lindsay
CEO
FABERGÉ
I was fortunate to be his Chief Financial Officer and together with his extraordinarily talented team was privileged to work on many of these ventures. Our partnership in the building of Billiton was one of the most satisfying periods of my career and he taught me many valuable lessons that I put to good effect when I was building Xstrata. I like to think that in combination we created value for shareholders, employees, communities and customers. We also shared a passion for opera and South African art.
He leaves a considerable legacy of remarkable achievements. There is an African saying that marks the death of people who have had great impact during their lives: A baobab has fallen! So it is with Brian.
Barbara and I pass on our deep sympathy and condolences to Rensche, Sean, Quinton, Ruth and Daniella and his grandchildren.
In Memory
The family respectfully request no flowers, please.
Should you wish to honour Brian's legacy, in lieu of flowers, the Gilbertson family welcomes any charitable donations to The PlettAid Foundation.
