With more than three decades of hands-on experience across exploration, mine development and operations, Thompson Mutezo stands out as one of Zimbabwe’s most accomplished mining professionals. A seasoned geologist by training, Mutezo has played a pivotal role in shaping some of the country’s most significant gold operations, successfully navigating volatile commodity cycles while delivering operational excellence.
In this interview, Mutezo shares insights into his professional journey, the strategic relationship between Pan African Mining and Ever Rising Resources, the technical innovations behind Muriel Mine’s landmark dump retreatment operation, and his vision for the future of mining in Zimbabwe.
Who is Thompson Mutezo?
I am a seasoned Geologist with over 30 years of experience. I’ve had the privilege of working with various mining companies in the region, exploring for gold and navigating complex business cycles. My journey with Pan African Mining began in 2013, rising to become the Group Exploration Manager. In 2021, I took on the role of Mine Manager at Muriel Mine, where I led a plant expansion program and drove engineering innovations to improve production efficiency. Later in 2024, I transitioned to Operations Executive at Ever Rising Resources, focusing on optimising production and managing costs.
Explain the relationship between Pan African Mining and Ever Rising Resources.
Pan African Mining established Ever Rising Resources as a special-purpose vehicle to raise capital for Muriel Mine’s dump retreatment project. This strategic partnership has enabled us to commission a state-of-the-art plant, optimising gold recovery and extending the mine’s life.
What are the key operational strategies you’ve implemented to optimise production efficiency while managing cost?
As the Operations Executive, my focus is on integrating technology, financial discipline, and people empowerment to drive sustainable growth. At Muriel Mine, I led initiatives to improve metallurgical efficiency, optimise reagent usage, and leverage data analytics. At Ever Rising, I’ve implemented production optimisation standards, driving efficiency and cost-effectiveness in the dump retreatment operation.
This is the largest dump retreatment operation in the country. Could you walk us through the technical processes involved and the innovations that make this project stand out?
Our dump retreatment operation is a testament to innovation and efficiency. We’ve implemented a high-volume, low-cost model, utilising hydrosluicing and CIL processes to maximise gold recovery. Our team has overcome complex metallurgical challenges, ensuring optimal recovery rates and minimal environmental impact.
What are the main metallurgical challenges associated with reclaiming and processing historical tailings, and how has your team addressed them to ensure optimal recovery rates?
Historical tailings present unique challenges, including ore variability and preg-robbing. We’ve addressed these through targeted interventions, such as converting to a full CIL plant and introducing pre-aeration stages. These innovations have improved leach kinetics and stabilised recovery.
From an exploration and resource evaluation perspective, how do you approach the assessment and classification of historical dumps compared to primary ore deposits?
We recognise historical dumps as known resources, focusing on understanding their composition, variability and metallurgical complexities. Our approach combines geological expertise with advanced data analytics, ensuring accurate assessment and optimal recovery.
Environmental sustainability is increasingly central to mining operations. What rehabilitation or environmental management frameworks has Muriel Mine adopted?
We’re committed to responsible mining practices, prioritising environmental sustainability and rehabilitation. Our frameworks include lined TSFs, cyanide detoxification, process water recycling and progressive rehabilitation, aligning with UN SDGs and industry best practices.
What is the future of Muriel Mine after the Dumps?
Muriel Mine is poised for a strategic return to run-of-mine operations, leveraging our extensive exploration program and expertise. We’re committed to extending the mine’s legacy while driving sustainable growth and community development.
What advice would you offer to young geologists and managers entering the industry today?
I advise young professionals to blend field expertise with digital tools, becoming versatile leaders in mining. Stay curious, innovative, and committed to sustainability, and you’ll drive the industry’s future success.
Your parting shots?
Exploration is the foundation of the mining industry. Without it, there are no new mines, no production, and no revenue. I urge industry leaders to prioritise exploration, investing in the future of mining and national economic growth.
