Mike Miller
CEO: Mantengu Mining
‘We’re still dealing with the back end of share manipulation and for us it’s clear we’ve been put in a position where we are sitting at a 90% discount’
MANTENGU’S focus is on mining investment with an aim to become a chrome and platinum group metals mining, mining services and energy company. But much of CEO Mike Miller’s energy has been consumed by his explosive allegations that the JSE has been involved in wrongdoing in the manipulation of Mantengu’s shares.
Miller claimed in May 2025 that his crusade on that front triggered a hit being placed on him by his opponents, alleging that mysterious drones flew over the company’s office and that he was being followed by shady characters with AK-47s. Such a scenario is not implausible in the crime-riddled gangsters’ paradise that is South Africa.
In November 2025, the Johannesburg High Court ordered Mantengu and Miller to stop publishing their allegations against the JSE. Mantengu said it would appeal the ruling and so more fireworks may get unleashed in 2026.
Meanwhile, Mantengu is continuing with its expansion projects. This includes its flagship Langpan chrome mine in South Africa’s Limpopo province where focus is also given to development of disadvantaged rural communities. Using a developed economy funding model, part of the company’s stated vision is to unlock capital, commodity and energy markets for small, black-owned businesses. In this regard, Miller and Mantengu see South Africa’s mineral endowment as key – a vision in sync with the dominant ANC and the feisty mining minister and ANC heavyweight Gwede Mantashe.
LIFE OF MIKE
A former game ranger, Miller these days tracks the spoor of mining finance opportunities when he’s not tracking skullduggery at the JSE. His passion for unlocking value from contested rural land is rooted in his time in the bush. Miller has a BCom and master’s degree from the University of Cape Town and was commercial manager at Dimension Data and founder of Disruption Capital – a varied and colourful background for a mining CEO. He has been CEO of Mantengu Mining since March 2023.
