Deep Yellow has appointed seasoned mining executive Greg Field as its new Managing Director and Chief Executive Officer, with his tenure set to begin no later than 1 May 2026.
The appointment follows a comprehensive leadership search undertaken as part of the company’s transition plan, with the Board prioritising a candidate with strong execution capability, a proven project-delivery record, and deep familiarity with jurisdictions in which the company operates, including Namibia.
Field, a qualified mining engineer, previously served as Managing Director – Project Development at Rio Tinto.
Over his 29-year career, he has built a reputation for delivering large-scale, technically complex resource projects across multiple continents and commodities.
His experience spans diamonds, copper, aluminium and lithium, with career highlights including major developments such as the US$7 billion Oyu Tolgoi underground project, the US$400 million Rincon direct-lithium-extraction plant in Argentina, and the US$1.3 billion AP60 aluminium smelter in Quebec.
Field began his career in South Africa and has prior exposure to Namibia, one of Deep Yellow’s most critical operating regions. He has lived and worked in Western Australia, Mongolia, the United States, Canada, Argentina and South Africa, bringing broad global operational insight into the role.
In accepting the appointment, Field said he was honoured to join Deep Yellow at a decisive moment for both the company and the broader uranium sector.
“I believe uranium has a key role to play in the global transition to clean energy, and Deep Yellow is uniquely positioned to contribute to that shift,” he said.
“I have been impressed by the depth of experience within the Deep Yellow team and the progress achieved on the Tumas Project. I am fully aligned with the Company’s strategy, and with two execution-ready projects in Tumas and Mulga Rock, the Company is well-positioned to capture the upside potential of the market and deliver long-term value to shareholders. I look forward to working with the Board and management team, with an immediate focus on progressing work on the Tumas Project.”
Executive Chair Chris Salisbury said Field’s arrival comes at exactly the right time as Deep Yellow prepares for a final investment decision on Tumas and the subsequent development phase.
“The Board is delighted to have attracted Greg to join Deep Yellow at the perfect time to own the near-term Tumas FID decision and then follow through with execution of this derisked growth project,” Salisbury said. “Greg brings considerable execution skills and extensive experience in delivering multiple large-scale resource projects which will further complement the existing expertise in the broader Deep Yellow team. The Company’s strategy remains unchanged, and we will continue the orderly derisking of the Tumas Project whilst also watching the uranium market develop the conditions necessary to support greenfield development.”
Field’s appointment is governed by an executive services agreement dated 2 December 2025, which outlines the terms of his employment, including short- and long-term incentive structures.
With uranium demand strengthening globally and Namibia at the centre of a new wave of supply potential, Deep Yellow is positioning itself to move from developer to producer under its new leadership.
