Brad Rogers has tendered his resignation as managing director of manganese producer Jupiter Mines.
Mr Rogers, who has spent four years guiding Jupiter, will begin as company president and chief executive of Canada-based North American Construction Group on December 1.
Until then, he will remain as MD of Jupiter, and between December and February next year, will offer consultancy services to the Perth-based midcap on a non-salary basis.
Matthew Jarvis – a mining engineer by trade across both Australia and South Africa – has been appointed interim chief executive of Jupiter.
Johannesburg-based Mr Jarvis, who has been with company since 2022, has extensive manganese and mining experience, along with firsthand experience of its flagship Tshipi manganese mine asset.
Jupiter chair Ian Murray said the board rates Mr Jarvis highly.
“With Matt’s manganese industry experience and experience in operations, mine planning and business development, we have long considered Matt to be a strong successor to Brad.
“We are delighted that he will have this opportunity to step into the new role. I look forward to working closely with Matt as we continue to drive Jupiter’s stated strategy forward.”
Jupiter produced 3.48 million tonnes of manganese at Tshipi during FY26, up from 787,905kt in FY25, which is located in South Africa’s Kalahari manganese field.
FY26 output also beat the historical annual production average of 3.4 million tonnes at Tshipi, an asset of which Jupiter has a 49.9 per cent stake.
