Deep Yellow’s new Managing Director and Chief Executive Officer, Greg Field, comes at a critical time when the uranium developer is preparing to convert years of study work into real mines and assert its place among the next generation of global producers.
Field, a seasoned mining executive with nearly three decades of experience, will take up the role no later than 1 May 2026, stepping into the leadership seat as Deep Yellow advances towards the long-awaited final investment decision on the Tumas Project in Namibia and the expansion of its Australian portfolio.
His appointment follows an extensive leadership search driven by the company’s desire for a chief capable of execution.
The Board emphasised the need for someone who not only understood complex multi-continent resource developments but could also steer two “execution-ready” uranium assets into production. Field fits that profile.
A qualified mining engineer, he previously served as Managing Director – Project Development at Rio Tinto, where he helped deliver some of the world’s largest and most technically demanding projects.
His track record includes involvement in the US$7 billion Oyu Tolgoi underground mine in Mongolia, the US$400 million Rincon lithium operation in Argentina, and the US$1.3 billion AP60 aluminium smelter in Quebec.
Field began his professional life in South Africa and spent periods working in Namibia, a country now central to Deep Yellow’s long-term strategy.
His international experience across Western Australia, Mongolia, the United States, Canada, Argentina and South Africa gives him familiarity with the regulatory and operating environments shaping modern uranium development.
Accepting the appointment, he said he was honoured to join Deep Yellow at a decisive moment for both the company and the global nuclear 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 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.”
Executive Chair Chris Salisbury welcomed Field, noting that his arrival comes at the perfect moment, just as Deep Yellow prepares to move from planning to construction.
The company’s strategy, Salisbury said, remains unchanged: derisk Tumas in an orderly manner, monitor the uranium market closely, and ensure conditions are strong enough to support greenfield development before committing capital.
“The Board is delighted to have attracted Greg to own the near-term Tumas FID decision and then follow through with execution of this derisked growth project,” he said.
Field’s appointment is supported by an executive services agreement dated 2 December 2025, which outlines his remuneration and short- and long-term incentives.
His leadership also intersects with a broader transition underway at Deep Yellow, which has been operating under interim stewardship since the October 2025 announcement that Chief Financial Officer Craig Barnes would act as CEO during the search process.
Barnes brings more than 20 years of experience in the resources sector, including 5 years as Paladin Energy’s CFO.
He is working alongside Executive Chair Salisbury to ensure stability during the handover period.
Field steps into a company describing itself as “proven uranium mine builders,” a claim underpinned by its asset base and strategic positioning.
According to the November 2025 corporate overview, Deep Yellow is the only ASX-listed uranium developer with two advanced projects—Tumas in Namibia and Mulga Rock in Western Australia—and one of the few globally with a genuine near-term pathway to multi-mine production.
The company holds a cash balance of A$203.5 million and no debt, a sign of financial strength as it advances engineering work and prepares for a greenfield build-out.
The Tumas Project, which sits within Namibia’s world-class uranium province bordering the Husab mine, has a 79.5 Mlb U₃O₈ reserve and a 30-year life of mine, with potential to extend to as much as 40 years.
Detailed engineering is progressing, with key plant areas around 50 per cent complete and procurement covering 92 per cent of direct capital costs already well advanced. An operational-readiness framework is underway to prepare for pre-production mining, plant commissioning and ramp-up towards an expected mid-2027 production start, subject to market conditions and Board approval. Deep Yellow has deferred the final investment decision until uranium prices move into a range that supports new greenfield supply, mirroring an industry-wide belief that, though tightening, the market is not yet fully incentivising new mines. Optimisation work delivered in 2025 has strengthened Tumas’s economics and confirmed its standing as a Tier-1 operation.
Mulga Rock, the company’s second major project, is also progressing, with feasibility revisions underway following successful resin-pilot work that confirmed the viability of producing uranium and critical minerals as separate streams.
Deep Yellow is now exploring the potential to convert Mulga Rock into a larger polymetallic operation, extending its life-of-mine beyond the current 15-year plan and elevating its strategic value at a time when nuclear fuel security is becoming a global priority.
Across both Namibia and Australia, the company positions itself within a global uranium market undergoing dramatic change.
Deep Yellow’s November 2025 brochure highlights booming nuclear demand driven by data centres, renewed US and European policy support, China’s sustained build-out and accelerating reactor plans in India and the Middle East.
At the same time, supply remains constrained after a decade of stagnation, with Kazatomprom signalling lower production and many formerly operating mines still mothballed.
The sector faces a talent drain and a shortage of shovel-ready projects, raising the question of where long-term, reliable supply will come from—a gap Deep Yellow hopes to fill with its dual-pillar strategy of organic development and targeted acquisitions.
With Field now stepping into leadership, Deep Yellow is effectively entering its most defining chapter yet. The company has spent years building a pipeline, strengthening its balance sheet and maturing its projects.
The next step—moving from developer to producer—will unfold under Field’s watch.
In a rising uranium market, with Namibia at the centre of a new wave of African supply, his appointment signals the company’s intent to transition into a Tier-1 global uranium producer capable of delivering more than ten million pounds annually across multiple mines.
