London-listed Hochschild Mining has appointed Cassio Diedrich as its new chief operating officer (COO), effective September 15.

Diedrich, a Brazilian mining engineer, brings more than 15 years of experience from Vale, where he held senior technical, operational and business roles, including serving as global head of mining and technical services for the group’s base metals business. He subsequently joined Glencore as head of business planning and mining and later served as global head of strategy and portfolio companies at Kinterra Capital.

Hochschild highlighted Diedrich’s extensive local expertise, noting its importance as the company completes an operational reorganisation of its Mara Rosa mine in Brazil and advances the Monte do Carmo gold project in the neighbouring state.

His appointment follows the recent naming of Ediney Drummond as country manager for Brazil, part of the company’s efforts to strengthen its senior management team and governance structure.

“I’m pleased to welcome Cassio to Hochschild. His extensive industry knowledge and strong local experience made him the clear choice for this role,” said CEO Eduardo Landin. “We are excited to have him on board and look forward to his contributions he will bring in the years ahead. This is an important time for Hochschild as we focus on maximising the performance of our existing operations while advancing our key growth opportunities.”
