History
Deep Yellow grew from a small Australian uranium explorer into a Namibia-focused developer, merged with Vimy in 2022, and has built Tumas to the brink of a funding decision that is now undated.
2006-2010: Uranium explorer finds its feet
Deep Yellow began 2006 chasing uranium in Australia, signing earn-in deals at Mt Isa and in South Australia. An entitlement issue raised $11.83 million at 7.5 cents, and drilling at Napperby in the Northern Territory followed. In October 2006 it agreed to buy Raptor Minerals, whose Namibian licences sat near Langer Heinrich, funded by a 1-for-5 entitlement issue at 12 cents. The deal completed in December 2006, with 955,433,697 shares quoted. A 2007 issue at 50 cents raised about $42 million, helped by a shortfall placement to Paladin Resources.
Namibia became the main focus. Drilling grew from one rig to five, and Tubas, Tumas, Inca and Aussinanis all received resource estimates. In December 2008 the company cut spending and retrenched staff, holding over A$50 million in cash with no debt. Toro Energy declined its Napperby option in 2010, returning the project to Deep Yellow. By October 2010, resources exceeded 100 million pounds of uranium oxide.
2011-2015: Resources grow, money runs short
The Omahola project in Namibia grew as Ongolo and MS7 resources were added, and the company lodged mining licence applications for Inca and Tubas Red Sand. Patrick Mutz resigned as managing director in January 2011 and Greg Cochran took over. Shiyela iron won a mining licence in February 2013, but no partner was announced.
Funding became harder. In June 2012 the company cut its drill rigs from seven to two and reduced staff. A 2-for-9 issue at 4.2 cents raised A$5.84 million, well short of the A$10.5 million maximum, and Laurium L.P. took a further placement for A$6.5 million. It also issued 129.33 million shares to end the Raptor earn-out. Later raisings were small: a A$965,900 share purchase plan in 2013 and a placement of about A$3 million in 2014. In 2014 the managing director called uranium prices unattractive.
2016-2019: Borshoff returns and Tumas takes shape
In October 2016 John Borshoff, who founded Paladin Energy, replaced Cochran as CEO. A Sprott affiliate paid A$1.415 million for 321.6 million shares at 0.44 cents. A 1-for-20 consolidation was proposed in January 2017, and a A$15.1 million raising at 25 cents followed, leaving 190.0 million shares on issue.
Drilling then found the Tumas 3 deposit, whose maiden resource was 23.5 million pounds in September 2017 and later rose to 31.2 million. By March 2019 the Tumas 1, 2 and 3 resources reached 67.4 million pounds. A June 2019 placement and share purchase plan raised A$11.29 million. A licence from Marenica gave access to its U-pgrade process, though the beats do not report how that testwork ended.
2020-2022: From study to merger
COVID-19 forced a cut in the work program in April 2020, with about A$13 million in cash. A scoping study that January led to a pre-feasibility study in February 2021, with a maiden Probable Ore Reserve of 31.0 million pounds. The company raised about A$40.8 million at A$0.65 per share. Chris Salisbury became chairman in May 2021, the Tumas ore reserve rose to 68.4 million pounds that October, and a mining licence application was lodged.
A Vimy Resources merger proposal lapsed in November 2021, but a new scheme was agreed in March 2022 and completed on 5 August 2022. It brought Mulga Rock in Western Australia and the Alligator River project in the Northern Territory. In December 2022 Deep Yellow agreed to end a royalty on Mulga Rock in exchange for A$14 million of new shares.
2023-2024: Licence granted, big raising
The Tumas feasibility study was released in February 2023, with capex of US$372 million and NPV (value of future cash flows) of US$341 million. Namibia granted the 20-year mining licence ML 237 in December 2023, and a re-costing put NPV at US$570 million at US$75 per pound. In March 2024 the company raised A$220 million at A$1.225 a share, with a share purchase plan also planned. Nedbank was appointed lead arranger for project financing, and Craig Barnes became CFO. In December 2024 the Tumas Ore Reserve rose to 79.3 million pounds, supporting a 30-year mine life.
2025-2026: Deferred decisions
The final investment decision on Tumas slipped repeatedly. In April 2025 the company chose a staged approach, with updated capex of US$474 million. A High Court review challenging the mining licence was filed in February 2025. Borshoff left in October 2025, and Greg Field became CEO from 2 February 2026. Paradice, the largest shareholder, was reported to be acting toward a board-composition meeting.
In 2026 the company agreed to buy ERA's 50% of the Cooper Creek joint venture for A$648,000, signed a NamWater water agreement, and gave Core Energy a path to 51% of the Nova joint venture. About A$34 million of Tumas civil contracts were awarded in July. On 16 October 2026, citing weak equity markets, it withdrew its Q4 2026 decision target. Civil works were funded from cash, and an updated value case was nearing completion. At 30 June 2026 it held net cash of A$160.0 million and no debt.
