Adam Treger is 16. A website he launched last year,, has interviewed some of the most media-shy figures in the mining industry. Adam's father is Julian Treger, the formidable fund manager behind royalty group Anglo Pacific. He is also a large investor in Firestone Diamonds, which is due to bring its 1m carat per annum Liqhobong mine in Lesotho into production this year. When Adam sits down with executives and politicians linked to mining, what are their views on the industry?

Tom Albanese

Tom Albanese was CEO of Rio Tinto until 2013. Q. What is your outlook on India? A. My outlook for India is continued GDP growth averaging 7% or more per year, for the next ten years or so. This GDP growth will lead to a doubling of the Indian economy sometime between 2025 and 2030. It will require more infrastructure and will certainly put a strain on all of the services. In my view, India will not follow the same path of development as China, first and foremost, because it does not have the solidarity of the Chinese Communist Party and the control and determination that comes with that central party. India’s growth will, in my view, be consumption led, whereas China’s growth was investment led. In India, people will begin to consume first. They will begin to construct buildings, and then the government will scramble to add roads, whereas in China, they built the roads first, and then everyone followed with buildings. India will always take a different path of development to China. India will not have the same speed of growth, and it may never grow as large as the Chinese economy. Q. Which commodities are you most positive about? A. I would be most optimistic in the next 12-18 months about the prospects for zinc, as many of the world’s largest mines are exhausting as we speak. I’m probably least optimistic about the prospects for aluminium, because the Chinese continue to develop new aluminium capacities, and although aluminium demand is strong globally, the supply seems to keep growing in excess of that demand growth. I would put copper, iron ore and oil somewhere in the middle of those extremes. Q. If you were starting your career today as a 16 year old, would you go into mining? A. When I was your age, I wasn’t thinking about what career I wanted to go into. I wanted to go to Alaska. So I packed a duffel bag of camping and climbing gear, and went to Alaska. My love of the outdoors led me to geology... Don’t plan it too hard, but make sure that whatever you do, you enjoy it, because that way you’re more likely to do well. FULL INTERVIEW >

Alan Winde

Alan Winde is Provincial Minister of Economic Opportunities for the Western Cape. Q. Do you think Jacob Zuma’s failures in the last six months have increased your chances in the regional elections? A. I think they absolutely have. Zuma’s failure from day one has really given us the growth we’ve been looking for over time. But lately, we’ve seen him mess up more and more often, and he has now gone past a tipping point. FULL INTERVIEW >

FW de Klerk

Frederik Willem de Klerk was the President of South Africa from 1989 to 1994. Q. Are you still positive about South Africa and its future? A. I am still positive about South Africa and its future. I think we’re facing a few rough years, but the recent judgment by the Constitutional Court has firmly reinstated South Africa’s position as a constitutional state and it found President Zuma and Parliament guilty of transgression of the constitution. This gives me a lot of hope. I expect a realignment in South African politics. The ANC alliance has started to break up, and we need it to happen. We need to move away from racially based politics towards policy driven politics, from old divisions to new formations. And I think that’s going to happen in the next 4 or 5 years. FULL INTERVIEW >

Lord Renwick

Lord Renwick was Britain's ambassador to South Africa until 1991. Q. How have you found the transition from politics to business. A. I was an ambassador. But I did work closely for ten years with Margaret Thatcher, so I was regarded as a Thatcherite. And I am an unrepentant Thatcherite, because she provided real leadership. She changed this country and its economy in dramatic ways: we are a much more prosperous and efficient economy than we were before. She was also a major figure in foreign policy; she had a huge impact on the world. I was involved with her in Rhodesia, in the Falklands, in getting our money back from Brussels and the single European act to try to complete the single market, and in South Africa. She made an enormous impact in Russia through her support for Gorbachev. When I left the Foreign Service, many things had been privatised, so I had to privatise myself. I was contacted by Flemings, the bank, and they said they’d like me to join, and I said that’s absolutely fine, but I don’t want just a door opening job, I want a real job. And they said fine, you can be part of a big capital markets team, helping to raise money for mining companies and listed companies in London. So I worked hand in glove with Ian Hannam, who is very well known in the capital markets business. We brought Billiton to London and then merged it with BHP, the world’s largest mining company. We helped build up Xstrata, and so on. It was very interesting, and my experience was relevant because some of it was based in South Africa and I had a lot of friends there. But you’ve just got to do it wholeheartedly, it’s no use looking back on what you were doing, you’ve got to throw yourself into what you’re doing now. FULL INTERVIEW >

Mmusi Maimane

Mmusi Maimane is the leader of the opposition party in South Africa. Q. Do you believe Jacob Zuma has abused his office for personal gain? A. Absolutely. The ANC is a patronage party and it is focused on benefitting its own network, its own friends, and the President is the kingpin of that. His key focus is in benefiting himself and his friends. FULL INTERVIEW >

Sir Mick Davis

Mick Davis was CEO of Xstrata, which merged with Glencore in 2013. Q. Is there a commodity that interests you at the moment? A. I will invest in any commodity where I think I will make decent returns. Base metals, like copper and zinc, are better to own than aluminium, simply because of the scarcity of the resources base. Bauxite, the key ingredient for alumina, which in turn is the key ingredient for aluminium, is in plenty of supply. If you’ve got availability of power you can produce aluminium relatively easily, so generally speaking, structural surpluses in aluminium are possible. Iron ore, a bulk commodity with high margins for the low cost producers is, not a commodity I would be keen to be exposed to. The three major producers have an enormous amount of capacity to produce more than they’re producing right now. They tend to produce as much they can to actually take out competitors. So if I had to choose the commodities which I like, I’d be in copper and zinc. Q. What are your thoughts about South Africa? A. It’s a very sad situation. It’s a country overcome by massive amounts of corruption, which is basically eating at the lifeblood of the economy. There’s enormous potential in the country, but I think the risks are very high. FULL INTERVIEW >
