Quarterly Report Dated 30 July 2026

Berkeley's June 2026 Quarterly Report covers continued exploration at its Conchas project in Spain and a maiden mineral resource estimate announced after quarter end. The estimate is 11.8 million tonnes at 0.41% Li2O and 0.21% Rb2O, containing about 49,000 tonnes of Li2O and 25,200 tonnes of Rb2O, with 100% in the Inferred category.

Mineralisation occurs in shallow, thick zones within a muscovitic leucogranite, from surface and open at depth, with accessory tin, caesium, beryllium, niobium and tantalum. The company says the resource suits bulk-tonnage open-pit Mining and that preliminary metallurgical testing showed good lithium and rubidium recoveries using flotation and magnetic separation.

Board Appointment and Spanish Nuclear Context

After the quarter, a former chief executive of Endesa, who has over 40 years of experience in the Spanish and EU nuclear and electricity sector, was appointed a non-executive director. The report also describes a request by the owners of the Almaraz nuclear plant to extend operations until June 2030 instead of closing in November 2027, which has been referred to Spain's Nuclear Safety Council.

The report describes metallurgical testing results as showing very good recoveries of lithium and rubidium at acceptable grades using flotation and magnetic separation, and notes that mineralisation from surface remains open at depth. The Almaraz extension request, submitted in October 2025 by Iberdrola, Endesa and Naturgy, was referred by the ministry to the Nuclear Safety Council for its report.

About Berkeley Energia

Berkeley Energia's report describes lithium as a critical and strategic material for the European Union and rubidium as classified as a critical mineral by the United States, Japan and New Zealand. It states that the Conchas resource hosts a globally significant rubidium resource.

The report states that the director's appointment strengthens the company's position and influence in Spain.

Risks and Catalysts on Watch

The resource is entirely Inferred, and metallurgical testing is preliminary. The company points to resource growth potential at depth as an exploration objective.
