The Founder

Aluizio Dutra has spent more than 25 years identifying, investing in and developing mineral opportunities across Brazil. Starting with private entrepreneurial capital, he built a track record of backing mining businesses from early development through operation and market access.

His investments in Piauí helped establish a new iron ore business in a region with no established iron ore mining industry at the time and contributed to the development of a new export corridor connecting the state to Atlantic markets.

Building the infrastructure around our investments

Lion Group takes an active approach to its investments, extending beyond capital into the infrastructure and logistics required to develop competitive mining businesses.

In Piauí, Lion Mining actively supported the development of the state’s new mineral export corridor, working alongside the State Government and Porto Piauí to advance a new maritime logistics solution. As an anchor participant in the emerging corridor, Lion Mining connects mineral production in the interior of Piauí directly to international markets through the state’s new port infrastructure.
