Cauldron Energy Boosts Uranium Resources and Wins WA Government Grants

Significant Resource Growth at Yanrey Uranium Project

Cauldron Energy (ASX:CXU) has reported a substantial expansion of its uranium resource base at the Yanrey Uranium Project in Western Australia, with a maiden Mineral Resource Estimate (MRE) for Manyingee North of 9.8 million pounds of uranium oxide and an upgraded Manyingee South MRE of 14.9 million pounds. These additions bring Cauldron’s total uranium oxide resources across three deposits to 55.6 million pounds, marking an approximate 80% increase since exploration recommenced in 2024 and a 32% uplift from the 2025 drill program.

The Manyingee North discovery, supported by 24 aircore holes drilled in 2025, lies about 8 kilometres northeast of Manyingee South and remains open in all directions, with airborne electromagnetic (AEM) surveys indicating the main palaeochannel extends over 8 kilometres further north. Meanwhile, Manyingee South, upgraded after 124 aircore holes drilled over two years, also remains open in three directions and will be a major focus for upcoming drilling.

Cauldron’s resource growth underscores the Yanrey Uranium Province as a globally significant uranium region, hosting approximately 100 million pounds of uranium oxide when including adjacent deposits held by Paladin Energy and Energy Metals. The company’s discovery of mineralisation at the Cosgrove prospect adds a fifth known uranium deposit within a 22-kilometre stretch of Early Cretaceous palaeocoastline, highlighting the extensive untapped potential of the region.

Government Grants Back Advanced Exploration Techniques

In a first for Cauldron, the Western Australian Government awarded the company two co-funding grants totaling up to $217,750 under Round 33 of the Exploration Incentive Scheme (EIS). The grants support a $157,000 passive seismic geophysics project and a $178,500 drilling program focused on the Ashburton East palaeochannel, both 50% co-funded by the government. An additional $50,000 was made available to offset international cost pressures.

Passive seismic surveying, proven effective in 2025 for defining complex palaeochannel networks at Manyingee South and North, will be expanded with a further 200 line kilometres of surveying planned between Cauldron’s Bennet Well and Manyingee North deposits. This technique enhances targeting precision ahead of drilling, reducing the risk of unproductive holes.

Cauldron’s success in securing these grants reflects recognition of uranium exploration’s strategic importance to Western Australia’s economic future. The company’s ongoing advocacy for lifting the state’s uranium mining ban aligns with this view, highlighting uranium’s potential to generate jobs and royalties while contributing to global decarbonisation efforts.

ETF Inclusions Signal Growing Market Recognition

Further boosting Cauldron’s market profile, the company was included in two prominent uranium-focused exchange-traded funds (ETFs): the Sprott Uranium Miners UCITS ETF (LSE: URNM) and the BetaShares Global Uranium ETF (ASX:URNM). Combined, these ETFs hold over 110 million Cauldron shares, representing 5.46% of the company’s issued capital.

Inclusion in these ETFs is a milestone for Cauldron, likely to enhance global investor awareness and broaden access to institutional and passive capital flows. This development supports liquidity and trading volumes, reinforcing Cauldron’s positioning within the nuclear energy thematic, which is experiencing strong momentum worldwide. The growing interest in uranium ETFs reflects the sector’s rising prominence amid expectations of a structural supply deficit and expanding nuclear power demand.

Strong Cash Position and Planned 2026 Drilling Campaign

Cauldron ended the quarter with a robust cash balance of approximately $3.9 million, down slightly from $4.5 million at the end of 2025 but with no immediate plans for further capital raising. The company realised around $450,000 from the sale of ASX-listed equity investments during the quarter, retaining investments valued at about $250,000.

Preparations for the 2026 drilling program are underway, with a heritage survey scheduled for May and drilling expected to commence in late May or early June, contingent on weather and passive seismic survey results. The program will prioritise Manyingee North and South, with the Cosgrove prospect also targeted given its early-stage mineralisation indications.

Groundwater analyses from Manyingee South, Manyingee North, and Cosgrove palaeochannels returned low levels of chlorine and sulphate, indicating suitability for in-situ recovery (ISR) mining methods. These findings, supported by testing from ANSTO Minerals, bolster the technical case for low-impact uranium extraction at Yanrey.

Strategic Partnerships and Advocacy for Uranium Mining

CEO Jonathan Fisher visited Cauldron’s partners Navoiyuran in Uzbekistan, pioneers in ISR uranium mining, to advance development planning and explore potential funding arrangements. The collaboration aims to leverage technical expertise as Cauldron progresses its project development.

Cauldron continues to advocate for lifting Western Australia’s uranium mining ban, emphasizing uranium’s role in energy security and global decarbonisation. The company submitted an extensive 104-page document to a WA parliamentary inquiry on the state’s role in global decarbonisation, highlighting uranium mining as a high-impact activity for economic and environmental benefit.

With uranium spot prices firming near US$87 per pound and global nuclear power investment accelerating, Cauldron’s integrated approach of resource growth, government support, market recognition, and strategic partnerships positions it well to capitalise on the sector’s momentum.

These developments build on Cauldron’s recent success in securing two EIS grants, as detailed in its $217K WA grants, and its inclusion in major uranium ETFs, which has been shown to enhance institutional visibility as noted in the BetaShares uranium ETF inclusion. Together, these factors suggest a company gearing up for an active and potentially transformative year ahead.
