Deep Yellow said incoming chief executive Greg Field will start on 2 February 2026, earlier than planned, as the company enters a decisive phase for the Tumas uranium project in Namibia.
The earlier commencement brings forward a leadership transition first announced on 2 December 2025, when the ASX-listed uranium developer confirmed Field’s appointment as managing director and chief executive.
At the time, Deep Yellow indicated that Field would assume the role no later than May 2026, following the departure of long-serving chief executive John Borshoff.
Deep Yellow executive chair Chris Salisbury said the board was pleased to have Field start earlier, noting that the timing aligns with a period of critical decision-making for Tumas and other projects within the company’s development portfolio.
Salisbury said the board was looking forward to Field’s leadership as Deep Yellow moves closer to key strategic and execution decisions.
Field replaces Borshoff, who led Deep Yellow through its evolution from a junior uranium explorer into an advanced development company.
During his tenure, Borshoff oversaw the consolidation of the Tumas uranium project, the completion of feasibility and engineering studies, and the early stages of development planning.
He stepped aside from the chief executive role as market conditions delayed a final investment decision, remaining involved at the board level during the transition.
A qualified mining engineer, Field joins Deep Yellow after a long international career with Rio Tinto, where he most recently served as managing director for project development.
His experience spans nearly three decades across large-scale mining operations and capital project delivery, a background the board has highlighted as particularly relevant as Tumas moves beyond technical derisking toward execution-focused decisions.
The leadership transition has been overseen by Craig Barnes, who served as acting chief executive following Borshoff’s departure.
Salisbury thanked Barnes for his role during the interim period and confirmed that he will return to his substantive position as chief financial officer once Field formally assumes office.
With engineering work substantially advanced, major equipment packages largely tendered and infrastructure agreements progressing, Field’s early arrival places a permanent chief executive at the helm as Deep Yellow assesses development timing, capital sequencing and readiness for construction at Tumas.
The move underscores the company’s intent to ensure leadership continuity and execution capability as it approaches one of the most consequential phases of the project’s development.
