Berkeley Energia is one of the few ASX-listed companies whose central asset has been halted by a regulator rather than by geology or the commodity cycle. The Perth-based group owns the Salamanca uranium project in western Spain, a development the company says had gathered more than 120 European and national permits before Spain's Nuclear Safety Council delivered an unfavourable report in July 2021 and the energy ministry, MITECO, refused the construction authorisation.

Almost five years on, Berkeley is fighting on two fronts. Inside Spain it is pursuing administrative appeals through the courts. Outside Spain it has lodged a treaty claim against the Kingdom of Spain at the World Bank's International Centre for Settlement of Investment Disputes, seeking compensation in the order of US$1.25 billion.

Latest announcement or development

The most recent price-sensitive disclosure was a maiden lithium and rubidium mineral resource estimate for the Conchas project, released on 21 July 2026.

A week later, on 28 July, Berkeley said a former chief executive of Endesa, one of Spain's largest electricity utilities, had joined its board. The appointment was not price sensitive, but it says something about strategy: a company in a protracted dispute with Spanish authorities recruiting from the Spanish power establishment. On 30 June it had issued an update headed International Arbitration Claim Against Spain.

Recent financial and operational performance

For the half year to 31 December 2025 Berkeley reported a net loss of A$3.446 million, against a A$831,000 profit a year earlier. The swing owed less to operations than to two items: arbitration expenses climbing to A$2.494 million from A$577,000, and a A$1.487 million foreign exchange loss where the earlier period produced a A$4.819 million gain. Net assets eased to A$76.056 million from A$81.368 million.

In the March 2026 quarter, operating cash outflows totalled A$2.815 million, of which arbitration absorbed A$1.835 million against A$759,000 on exploration and evaluation. Litigation, not drilling, is the largest single expense.

Business model and principal assets

Salamanca sits about three hours west of Madrid. Company disclosures put the total mineral resource at 82.6 million tonnes grading 514 parts per million U3O8 for 89.3 million pounds of contained uranium, across Retortillo at 14.5 million pounds, Zona 7 at 30.2 million pounds, Alameda at 21.1 million pounds and smaller satellites.

The definitive feasibility study drew only on measured and indicated categories, some 59.8 million pounds, leaving inferred material outside the mine plan. Berkeley has stated the project was designed to produce more than four million pounds of uranium a year, about a tenth of European consumption on its own reckoning. None of that is producible while the authorisation position is unresolved.

Growth opportunities

Three routes could change the picture, none fully within management's control. The first is the ICSID claim, where a favourable award would convert a stranded asset into cash, though quantum, timing and recoverability rest with the tribunal. The second is the domestic appeal: were the Audiencia Nacional to set aside MITECO's refusal, the permitting pathway would reopen rather than conclude.

The third is critical minerals. Conchas has moved from flotation test work, which the company reported returned 78 per cent lithium and 63 per cent rubidium recoveries, through geological modelling and pit optimisation to this month's maiden estimate. Berkeley notes rubidium is designated a critical mineral by United States and Japanese authorities.

Balance sheet, funding and cash flow

Berkeley closed the March 2026 quarter with A$63.996 million in cash and no debt, down from A$68.408 million three months earlier, the A$4.412 million reduction reflecting spending and currency movements. Management estimated funding available for more than ten quarters at the then-current rate of expenditure.

That is comfortable for a pre-revenue explorer and explains how Berkeley has funded a multi-year arbitration without returning to shareholders. It is not construction money: should authorisations ever be restored, substantial project finance would be needed, on terms that cannot be assessed today.

Principal risks

Jurisdiction risk dominates. Berkeley has had a construction authorisation refused and, in December 2023, saw the High Court of Justice of Castilla y Leon revoke land-use and urbanism permissions granted in 2017 and 2020. It withdrew cassation appeals to the Spanish Supreme Court to preserve its arbitration rights, a trade-off that narrowed its domestic options.

On the arbitration side, Spain has requested bifurcation so jurisdictional objections are heard separately, which can add considerable time before any hearing on the merits, and sovereign respondents have a history of contesting enforcement. Beyond the legal file sit the ordinary hazards: no revenue, unrealised exposure to a volatile uranium price, and, as the seven-share print shows, stretches of very thin trading.

Outlook

The near-term calendar is procedural rather than operational. Spain's response to the Memorial of Claim was due during July 2026, with scope to extend into October if the tribunal agrees to hear jurisdiction separately. The April 2023 appeal to the Audiencia Nacional remained undecided in the disclosures reviewed.

On the ground, work continues at Conchas and the company has signed a cooperation agreement with the Municipality of Retortillo covering water system renewal and a healthcare centre. The honest summary is that Salamanca is neither approved nor formally abandoned. It sits inside a legal process nobody can date, and a small move on seven shares says nothing about where that process is heading.
