Deep Yellow Limited (DYLLF) Adds to Alligator River Project With Stake in Cooper Creek JV Acquisition

On June 29, 2026, Deep Yellow Limited announced a binding agreement to acquire Energy Resources of Australia’s 50% stake in the Cooper Creek Joint Venture for $648,000 in cash. The transaction adds 810km² of exploration tenure to Deep Yellow’s portfolio within the Alligator Rivers Uranium Province (ARUP), situated contiguous to the company’s existing tenements.

The development serves as a minor sector update regarding greenfields exploration activity in a historically significant but currently non-producing uranium province.

Cameco Corporation (CCO) completed the acquisition of Deep Yellow, a transaction characterized as routine that does not alter the company’s valuation, production profile, cost structure, or risk matrix. The market’s reaction, marked by price consolidation between $140 and $155 in June, reflects the lack of material impact from the deal.

The stock has pulled back approximately 19% from its January peak, a decline that prices in near-term operational risks including Key Lake maintenance and flood recovery efforts, as well as tariff uncertainties. This movement also coincides with the market digesting the transformative $80 billion Westinghouse partnership. There is no change to the investment thesis or rating based on this release.

Cameco Corporation is a leading global uranium producer and nuclear fuel services provider. Its flagship assets include the tier-one, high-grade Cigar Lake mine, the McArthur River and Key Lake operations in Saskatchewan, Canada, and the JV Inkai project in Namibia. The company also provides fuel services through its Port Hope conversion plant and participates in uranium enrichment via a stake in Westinghouse. Cameco owns 49% of Westinghouse, which is benefiting from a US government partnership for the deployment of the AP1000 reactor.
