Appointment of Chief Operating Officer
Hochschild Mining PLC ("Hochschild" or "the Company") (LSE: HOC) (OTCQX: HCHDF) is pleased to announce the appointment of Cassio Diedrich as Chief Operating Officer from 15 September 2025.
An experienced Mining Engineer, Cassio began his career at Vale, where he held a number of senior responsibilities including technical, operational and business roles over 15 years, latterly as Global Head of Mining & Technical Services for the Vale Base Metals business. Recently, Cassio then held the role of Head of Business Planning and Mining at Glencore for two years before becoming Kinterra Capital's Global Head of Strategy & Portfolio Companies.
With considerable local experience, Cassio is a Brazilian national whose local expertise will prove invaluable, with Brazil being a key market for Hochschild as it completes an operational reorganisation of its Mara Rosa mine and continues to progress Monte Do Carmo, a gold project in the next-door state to Mara Rosa. This follows the recent appointment of Ediney Drummond as Country Manager for Brazil, as the Company evolves its Senior Management team and implements a new governance structure.
Eduardo Landin, Chief Executive Officer commented:
"I'm pleased to welcome Cassio to Hochschild. His extensive industry knowledge and strong local experience made him the clear choice for this role. We're 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."
