Michael Nunn

Nickname: 'Mike'

Leading South African Mining Entrepreneur

Mike Nunn is a South African mining entrepreneur, investor and philanthropist. His formative youth was spent in orphanages in England. He immigrated to South Africa at the age of 19. He has no formal education or qualification. Nunn has 25 years hands-on mining industry experience and has founded and developed various businesses and charitable initiatives, primarily in the mining and resources sector in Africa.

Nunn's mining industry career began in Zambia in the early 1990's, where he developed an emerald business, followed by tourmalines in Namibia in the mid 1990's and then moved to Tanzania and tanzanite. From 1998 to 2005 Nunn built up effective control of the world market for both rough and polished tanzanite through his company, TanzaniteOne. Although he is on record denying he ever achieved actual control, at one point it was estimated that as much as 70% of the worlds tanzanite was either produced from his mines or traded and marketed through his company, Nunn has become widely recognized as being the pioneer of the global tanzanite market. He founded and subsequently listed TanzaniteOne on to the AIM market of the London Stock Exchange. During Nunn's stewardship TanzaniteOne became one of the largest taxpayers in the Tanzanian mining sector and the highest dividend payer in the mining and resources sector of the London AIM.
Nunn also established the Tanzanite Foundation, a non-profit organization intended to be the industry's so called 'guardian'. The Tanzanite Foundation assured both the trade and consumers of tanzanite's ethical route to market through the proper payment of royalties and taxes at origin, and by channelling funds from the sales of tanzanite back into the communities at its source. Community initiatives of the Tanzanite Foundation included the electrification of rural villages in the tanzanite mining region, construction of a primary and secondary school for 600 pupils, equipping community infrastructure, medical facilities, and construction of a place of worship and maintaining critical village access roads, positively impacting the lives of many Tanzanians.

In 2005 Nunn left TanzaniteOne and the tanzanite industry to concentrate on the development of Amari, a company with various mining interests which included diamonds, gold, nickel, platinum, coal, manganese and mining engineering services. Amari had operations in various sub-Saharan African countries, in particular Angola, Central African Republic, DRC, South Africa and Zimbabwe. By 2013 Amari had developed and either sold or listed most of its assets.

In 2012 Nunn emigrated from South Africa and now resides in London, from where he established Kropz International SARL, an explorer, mine developer and miner of fertilizer feed minerals, primarily phosphates, in west and sub-Saharan Africa.

In 2014, Nunn and his wife established Jeluka4Good, a family philanthropic initiative. Jeluka4Good supports various charitable initiatives, mainly within the sub-Saharan African region, with an emphasis towards assisting deprived children.

In 2016 Nunn co-founded Greenheart Foundation together with Umbunto-Botho and The Motsepe Foundation. Greenheart Foundation is a non-profit entity through which community, socio-economic, charitable and environmental initiatives, particularly substance abuse rehabilitation, is being undertaken.

Nunn is married and has 3 children.
